What is a bulb? 

A bulb is an interactive video created in PlayPosit. Transform any video into an active experience for students by embedding questions, images, audio, and other media elements. To start creating a new bulb, click Add New Bulb from the dashboard.

Insert a video 

The PlayPosit Designer supports adding videos from a multitude of sources. However, only institutional account holders will be able to access videos from premium video hosts like Kaltura, Panopto, Wistia, Zoom, and Mediasite. All users, however, can use unlisted or public YouTube or Vimeo videos in their bulbs, and all users will be able to see videos they have previously built into bulbs when they click the My Videos button.

If you have a specific YouTube or Vimeo video URL that you'd like to use, click Input URL and paste the link into the given field.

Add multiple video clips to a bulb

When you add multiple video clips to a single bulb, your students will experience a seamless video storyline experience. To add multiple videos within a bulb, follow these instructions:

  1. Click the Video Segments tab header and then click Add Video.
  2. Repeat the same steps as in the above section to finish setting up this video segment.
  3. You will see multiple videos in the list, and you will be able to scrub between the different videos on a single sidebar.

Upload or fetch captions

The PlayPosit 3.0 designer supports uploading .vtt and .srt caption files, as well as fetching caption files that are already attached to video streams from other media hosts like YouTube, Kaltura, and MediaSite.

Note: If you are part of an institutional license, all captions will be auto-fetched eliminating the need to click fetch. To enable live transcripts for Youtube videos, you must fetch captions.

  • Switch to the Video Segments tab.
  • Click the triple dots icon for the video you want to caption and select Edit Video Segment.
  • Click Customize.
  • From here, you can either drag and drop caption files directly over the dialog menu, or click Fetch YouTube Captions to retrieve existing caption files for that stream.
  • To learn more about how to set your captions to autoplay in your Bulb, click here

    Note: We recommend checking all .srt and .vtt files with a srt checker before upload so any formatting errors can be caught that could affect playback. A recommended online checker is

    5. Once captions are automatically fetched or uploaded, you may use in them in the player. When previewing a bulb in the player, select the captions you would like to use by clicking the Settings Gear.

    6. Select the captions you would like displayed from the dropdown.

    Note: Captions that are uploaded from a .vtt or .srt files will show up in the drop down labeled as the chosen file name and will display for the bulb viewer.

    Edit captions

    If you need to edit a caption file to fix a typo or alignment, you can follow these directions.

    1. Inside the designer, click the Video Segments tab and select the video. 
    2. Click Captions then the caption you would like to edit. Then, select the link icon
    3. The captions will open in a separate tab. Right click on the screen and select Save As...
    4. Name the caption file and then open it up in a text editor.
    5. Once you have made the edits, save the file, then upload it by following the directions above.  

    Trimming and cropping video

    If your video is too long or covers topics that aren't relevant to you, you can either trim the beginning and end of the video, or add internal crop segments.

    1. Switch to the Video Segments tab.
    2. Click the triple dots icon for the video you want to caption and select Edit Video Segment.
    3. Click the Trim & Crop tab.
    4. To trim video from the beginning and end, drag the first set of red and green handles, or click Advanced and type in the exact timestamps you want to trim the video to.
    5. To add internal crops, click Advanced > Add Internal Crop. You can then drag the new sets of red and green handles that appear, or type in the exact timestamps you want to trim the video to.
    6. Click Done to save your changes and close the dialog.

    Changing a video source

    If you want to replace a video segment that you have already added:

    1. Click on the thumbnail of the video segment you want to replace.
    2. Click the dropdown menu above the video preview. (It may read something like "Current YouTube video)
    3. Choose your new video source.

    All interactions which you have already added will be preserved when you change the underlying video source.

    Change a video name

    Change the name of a video in a bulb to organize different sections of the bulb.

    1. In the designer, select the video in the Video Segments tab. 
    2. Under the Video Source tab, edit the Title section to change the video's name. 
    3. The video title will appear in the designer and on the player in the Review tab. 

    Note: When the title of the video is changed, it will not impact other bulbs using the same video.

    Insert interactions

    To insert a single interaction, switch to the Interactions tab, and click Add an Interaction.

    Before you can save the interaction and close the dialog, you may need to:
    • Add text to the question prompt
    • designate a correct answer

    Otherwise, the dialog will not allow you to save and close.

    Types of interactions

    PlayPosit offers 8 different types of interactions, each of which can be customized in a variety of ways:

    Multiple choice: Present students with a series of options to choose from in response to a question. This question type has one correct answer and is auto-graded.
    Check all: Present students with a series of options to choose from in response to a question. This question type can have multiple correct answers, but students will only receive full credit if they select  all of the correct answers. This question is auto-graded. 
    Free response: Allow students to demonstrate understanding with a text response and/or use the rich text editor to include images, audio, equations and tables. This question type is manually graded.     
    Fill-in-the-blank: Present students with a phrase that is missing one or more words. Questions can have multiple blanks and multiple correct answers. Learners can receive partial credit for their answers, and this question is auto-graded.
    Reflective pause: Give students the opportunity to pause and reflect on video content. Alternatively, use this question type to supplement information that is not covered in the video, or make connections between the video content and other course material. This interaction is not graded by default, but you can change the point value if desired.
    Web embed: Allow students to explore a website without leaving the video lesson. Use this to provide supplemental information to students or have them complete an online simulation. This interaction is not graded by default, but you can change the point value if desired. 
    Polling survey: Present students with a series of options to choose from in response to a question. Student can only choose one option, and there is no right or wrong answer. This interaction is not graded by default, but you can change the point value if desired.
    Discussion forum: Simulate an interactive discussion with this question type. Students can post responses in real time and/or reply to comments posted by other students. This interaction is not graded by default, but you can change the point value if desired. 
    Table of contents: Creates an outline of your bulb in the sidebar. This table includes all video clips and interactions which can be clicked to jump to the time each occurs in the bulb.
    Note: The Table of contents interaction type is only available to school users at this time. Free and Pro users cannot use this type of interaction. Please contact your account manager for more information.      

    Interaction templates

    Interaction templates are a quick and easy way to add pre-formatted interactions to your bulb. They can be found by clicking Add An Interaction and scrolling down to the bottom of the menu. Please see the Interaction templates article here for more details.

    Template gallery

    The template gallery contains bulb templates that apply either multiple interactions at the beginning, middle, or end of your bulb, or durational interactions over the entire length of your bulb. It can be accessed in two different ways:

    1. After adding a video segment, select Apply Template.
    2. Selecting the Interactions tab and clicking Open Template Gallery.

    See this article for more details.

    Adding feedback

    To add feedback to individual answer choices for multiple choice, check all, or polling survey interactions:

    1. Click the gear icon next to the answer choice and select Add Feedback.
    2. Type out your feedback.
    3. Click Done to close the dialog.

    Embed images, audio, attachments, equations, and tables

    You can use the rich text editor to add images, audio, equations, tables, links, and more to any interaction, with the exception of web embeds.

    Clicking in any editable text area will bring up the rich text editor toolbar. Click the triple dots icon on the toolbar to expand it and show even more options for formatting your interaction.

    It is also possible to directly edit the HTML of an interaction. Click here for more information on what HTML tags are allowed and how to edit them.

    Note: Attachments can be added to an interaction if you are part of an institution with this feature. Admins for institutional licenses should contact their account manager for more information.

    Attachments can be added by clicking the paper clip icon in the rich text editor and then selecting a file from your computer's browser to upload. All file types are supported except for audio, video and images. After uploading the attachment you will see a chip with the name of the file you have uploaded appear in a new section below the rich text editor under Attachments. If you need to delete the attachment click the x button on the chip.

    Attachments can be placed in an interaction description, answer or feedback options.

    When a learner takes the bulb, they will see the attachment appear in the interaction. They can click the attachment icon to download the file directly to their computer.

    Change the point value of a question

    By default, when you create new interactions, the Designer will automatically set them to be worth the same number of points as is specified in your profile. However, if you want to change the point value of an individual interaction, you should:

    1. Click on the triple dots icon for the interaction you want to edit.
    2. Click and drag the slider next to the point value (10 points maximum)

    Advanced interaction settings

    Certain interactions have more advanced features available to them, all accessible by clicking Advanced underneath the interaction.

    Partial credit

    When you check " Learners can earn partial credit" on a fill-in-the-blank question, learners will receive points for each blank they get correct.

    When you click Done, the interaction will update to reflect the exact points that each correct answer is worth.


    If a learner selects a specific answer, or if they get a question right or wrong, you can jump the learner to a different point of the video.

    To add a jump to specific answer options (multiple choice, polling survey):

    1. Click the gear icon next to the specific answer option and select Add Jump.
    2. Drag the slider or type in a specific timestamp.
    3. Click Done to save and exit the interaction dialog

    Otherwise, to add a jump if the learner answers a question correctly or incorrectly (fill-in-the-blank, check-all):

    1. Click Advanced at the bottom of the interaction dialog
    2. Check one or both of Jump if the user answers this question correctly and Jump if the user answers this question incorrectly.
    3. Drag the slider or type in a specific timestamp.
    4. Click Done to save and exit the interaction dialog.

    If you want to jump the learner forward in a bulb, you must enable fast-forwarding in Bulb Settings, and all intermediate interactions (i.e. between the original interaction and the jump destination) must be set to not required. Similarly, if you want to jump the learner backward in a bulb, you must enable rewinding in Bulb Settings. Click here for more information.


    You can set all interaction types to appear in either the sidebar or a video overlay, more commonly referred to as a "hotspot." This is supported for all interaction types.

    To change the way an interaction displays, you can either open the interaction editor and click Customize, or click on the position information on an interaction, directly underneath the blue timestamp.

    This will open the interaction editor to the Placement tab, where you can select whether this interaction will appear in the sidebar or a video overlay, aka "hotspot."

    Finally, if you select a hotspot location and then click Advanced, you will have many more options for customizing your interaction's hotspot, including size and opacity.

    This section contains settings for nudging your video content from the left and top. In addition, the width or height of the content may be edited from this menu. Transparent may be selected to show or hide the position for your content in the "Placement" window. Epandable can be selected to add the ability to shrink and expand your content in the viewer. Collapsible can be selected to add the ability to collapse the content in the viewer.


    By default, when you add an individual interaction, that interaction will appear and disappear at a specific time in the video. However, you can set it to be visible for however long you want if, for example, you want to show an annotation over the video for a while, or let your students use the video as a resource to answer a question. This is enabled for all interaction types.

    To adjust a question's timing, open the interaction and click Customize twice, or click on the timestamp to the left of the interaction's triple dot icon.

    Next, click Advanced to expand the start and end times, and edit them however you'd like.


    By default, students can only attempt each interaction once, but teachers can set individual interactions to have up to ten retries, or unlimited retries. This is supported for multiple choice, check all, polling surveys, free response, and fill-in-the-blank interactions.

    To enable them, open up an interaction, click Advanced, and then check the box next to Allow more than one attempt

    Finally, drag the slider to the number of attempts that you wish to enable for that interaction. 

    Manually graded discussion forums

    Note: This feature is currently only available for certain institutional users. 

    By default, when a learner submits a comment to a discussion forum that is worth points, they will automatically receive full credit. However, it is possible for instructors to configure discussion forum interactions such that they are manually graded instead, i.e. learners will not receive credit until the instructor views their response in the bulb gradebook and manually assigns a point value.

    1. Click the triple dots icon on the discussion forum for which you would like to enable manual grading.
    2. Select Edit.
    3. Click Advanced.
    4. To enable manually-graded discussion forums, uncheck the checkbox labeled Learners automatically earn full points on submission of comments.
    5. Click Done.

    For more information on how to grade manually graded discussion forums, click here.

    Randomized answer order

    To prevent cheating on certain interaction types, you can set answer options to display in randomized order each time. This is supported for multiple choice, check all, and polling survey

    Show feedback for unselected correct answers

    Note: This feature is available for all institutional users.

    When you add a check all interaction, you can choose to show feedback for unselected correct answers.

    1. Add an interaction with multiple correct answer choices and feedback.

    2. Click Advanced and then check Learners see feedback for unselected correct answers.

    3. When a learner takes the bulb they will see other correct answers displayed with custom feedback if they do not select all the possible correct answers.

    Only show feedback on last attempt

    Note: This feature is available for all institutional users.

    You can configure a multiple choice or check all interaction to only show answer feedback when the learner has no remaining attempts on the interaction, or show feedback after every single attempt.

    1. Create an interaction with feedback in the answer choices.

    2. Click Advanced, check Allow more than one attempt and Only show feedback on last attempt.

    3. When a learner answers an interaction, they will see feedback displayed after their last remaining attempt if they answer incorrectly. If Only show feedback on last attempt  is unchecked, then the learner will see feedback displayed after every attempt.

    Never show correct answer

    Note: This feature is available for all institutional users.

    You can configure a multiple choice, check all, or fill in the blank interaction to never show answer highlighting. This means the learner will not be informed of whether a response is correct or incorrect. 

    1. Create an interaction and select the correct answer choice(s).
    2. For Check All and Fill in the Blank, under the Advanced options, select Only show answer highlighting on last attempt and select Never show answer highlighting. Choose any other options then click Done Learner view: 
    3. For Multiple choice, under the Advanced options, select Hide correct answer if not selected and choose to Never show answer highlighting or keep it unselected. Determine any other options then click Done

    Learner view: 

    Note: If Never show answer highlighting is selected, learners will not see highlighting for correct, incorrect, or missed answer selections. They will also not see the points earned or points available. Learners will only see a pop up notification that confirms their answer has been submitted.

    Dark Mode

    Note: This is only available for specific institutional partners. If this feature is something your institution is interested in, please reach out to your Account Manager or

    In the designer, create a Multiple choice or Check all interaction. 

    Select Placement

    Place the interaction in the video frame. Once you do this, the Advanced Settings will appear. 

    Select Advanced and toggle on Dark mode. Adjust the Opacity slider or type in the percentage. When finished, click Done. 

    Chain and stack questions together

    When you add an interaction, it usually appears as a stand-alone interaction. However, it is possible to set interactions to display in a group, so that your students need to answer a series of questions at a time before they can continue watching the video.

    On any interaction (depending on whether or not it's already in a group), you can click the triple dots icon to:

    • Add Interaction Before or Add Interaction After - Add a new interaction before or after the selected interaction, effectively creating a group of interactions.
    • Separate From Group - Remove the selected interaction from an existing group so that you can edit it individually
    • Move Interaction Back or Move Interaction Forward - Move the selected interaction earlier or later in the group so it displays sooner or later.

    Bulb settings

    If you click the Review tab, you will see a number of bulb settings you can change that will affect the way your bulb plays back and displays to both your fellow teachers and to the students taking your bulb.

    Change bulb thumbnail

    Edit the bulb thumbnail by clicking on the picture in the Bulb settings. This thumbnail will display in the My Bulbs library, on student dashboards (if they log in to PlayPosit), in Premade Bulbs (in certain cases), in the Designer, and in the Player.


    Tags allow you to sort and manage your bulbs by custom keywords, audience, and subject area. For example, if you have five bulbs for a unit on Geometry, and four bulbs for a unit on Algebra, you can tag your content to easily organize and share them.

    1. From the Review tab of the Designer, click Tags to expand that section.
    2. Next, either type or select the tags that you want to apply to this bulb and click Save.
      1. Keywords/Tags are user-generated content. You can type any keyword you want to use in this field.
      2. Target Audience is a PlayPosit-generated list of options that you can choose from. Click here to request new entries.
      3. Subject is a PlayPosit-generated list of options that you can choose from. Click here to request new entries.

    Playback options

    Click Playback Options to expand that section and check the desired boxes.

    • Allow learners to rewind after an interaction appears - Learners can rewind as far as the beginning of the video while they are answering an interaction. (Learners can always rewind as far as the beginning of the video after answering an interaction)
    • Allow learners to skip interactions - Learners can choose not to answer interactions and keep watching the video.
    • Allow viewers to fast forward - Viewers can fast-forward up to the next required interaction.
    • Allow learners to retake the bulb upon completion - Learners can retry an entire bulb when they are done watching the video, but doing so will set their score back to zero until they finish watching the entire bulb again.
    • Allow learners to view their printable report - Learners can download a printable worksheet of their answers once the bulb has been completed. Instructors may enable this option as a way for students to have a certificate of completion. Students may use this report to review and study at a later date. *NOTE: This option is for institutional clients only.
    • Allow learners to increase playback speed - This option will automatically be enabled for all bulbs. Instructors can now have the option of disabling playback speed so their students are unable to speed up videos. *NOTE: This option is for institutional clients only.


    Click Privacy to expand that section and select the desired privacy setting for your bulb. These settings will override your profile defaults, which you can read more about in this help article.

    Previewing a bulb

    It is possible to preview a bulb as either an instructor or a learner from the PlayPosit Designer. Previewing a bulb as an instructor will allow the viewer to fast-forward to any point in the bulb, as well as to skip questions. Previewing the bulb as a learner will restrict the viewer to viewing the bulb as a learner would, essentially defaulting to the bulb's built-in playback settings. It is possible to switch between the two previews at any point in time.

    On first launch

    In the  Review tab of the designer, click the Preview button. This will open a new tab containing a player preview.

    When the player first loads a bulb preview, a toast will appear in the top right corner of the screen. 

    Selecting "Toggle Playback Mode" will open the settings gear menu, which will allow you to choose your preview mode

    Instructor preview

    In the Review tab of the designer, click the Preview button. This will open a new tab containing a player preview. By default, clicking Preview will open an instructor preview of the bulb, but the following instructions will show how to switch back to an instructor preview.

    1. Click the Settings Gear in the bottom right. 
    2. Then, next to Playback Mode, select Instructor from the dropdown menu.

    You will now be able to skip to any part of the bulb and skip any questions that arise.

    Learner preview

    1. Click the Settings Gear icon in the bottom right corner.
    2. Select Learner from the dropdown menu labeled Playback Mode.

    You will now see the bulb the same way a learner would, which is determined by the bulb's playback settings. 

    Note: If you are switching from an instructor preview to a learner preview, and had previously skipped any required questions, the player will jump you back to the first unanswered question, regardless of your progress in the video.
