1. Video resolution, aspect ratio & format

It is not possible to change the video resolution, aspect ratio, or format of your video.

Here are the default values:

  • Video resolution: Full HD 1080p resolution (1920×1080 pixels)

  • Video format: MP4.


2. Video & script length

Video length

The maximum length of your video depends on your Synthesia STUDIO plan.

  • Personal plan (10 video credits/6 slides)

    Video length: The maximum length of your video is 10 minutes. Each slide can be up to 5 minutes in length. This means that, for example, you can choose to create a video with 2x slides of 5 minutes each, or 5x slides of 2 minutes each, etc.

    Slides: The maximum amount of slides you get is 6. It is not possible to buy additional slides or create one-off videos with a custom amount of slides.

  • Corporate plan:

    Video length: The maximum length of your video is 2.5h. Each slide can be up to 5 minutes in length.

    Slides: The maximum amount of slides you get is 50.

Script length

For the majority of languages, the maximum length of the script is 3500 characters per slide.


Exceptions:

  • Mandarin: 1200 characters max.

  • Cantonese: 750 characters max.

  • Japanese: 1250 characters max.

  • Korean: 1600 characters max.

Please note that if the script doesn’t exceed the character limit, it may still fail to generate if the final slide would exceed 5 minutes. This can happen if you use a lot of <break> tags in your script.


3. Image upload size & format

  • Upload size: maximum 300MB

  • Supported formats: jpeg, png, svg.


4. Video upload size & format

  • Upload size: maximum 300MB

  • Supported formats: .mp4, .webm.


5. PowerPoint upload size & format

Please note that on a personal plan, you can upload a maximum of 6 slides, and on our corporate plan - 50+ slides.

  • Upload size: maximum 300MB

  • Supported formats: .ppt, pptx.


6. Supported browsers

For the best experience, please use Google Chrome. We have limited support for other browsers (Firefox, Safari). You can close your browser while the video is rendering - your video will not be lost.

We do not have a desktop application.


7. Multiple avatars on a slide

Currently, it is not possible to have two avatars on one slide "having a conversation", but you can use our Modelling a Dialogue - Learning Template for similar capabilities.


8. Avatar appearance

It is not possible to change the avatar's appearance or clothing. You can create a custom avatar with your preferred appearance/clothing.


9. Video stats

Currently, we do not support video analytics. We are working on adding this capability in the future.


10. Closed captions

You can add or download closed captions.
