Conference Video Guidelines
All authors of talks for the CWL Conference are required to upload a pre-recorded video presentation and a short summary (aka blurb) describing their talk (<150 words).
Please contact conference@commonwl.org if you have any questions or issues with the submission process.
Since the presentations will be uploaded to YouTube, we need your talk recording format to match the requirements for YouTube.
- Container: MP4
- Frame Rate: Content should be encoded and uploaded in the same frame rate it was recorded. Common frame rates include: 24, 25, 30, 48, 50, 60 frames per second (other frame rates are also acceptable).
- Aspect Ratio: The standard aspect ratio for YouTube on a computer is 16:9.
- BitRate:
- For Frame rate of (24, 25, 30) the suggested Video Bitrate is 35-45 Mbps (2160p / "4K"), 16 Mbps (1440p / "2K"), or 8 Mbps (1080p)
- For Frame rate of (48, 50, 60) the suggested Video Bitrate is 53-68 Mbps (2160p / "4K"), 24 Mbps (1440p / "2K"), or 12 Mbps (1080p).
- Resolution: Ideally, we want the talks in high resolution. For the default 16:9 aspect ratio, we suggest encoding at 1080p: 1920x1080 (see more here)
Listed are several tools available to record your presentation with additional links on getting started with these tools. You can show your face via webcam (if you'd like) and display your slides as you talk. Please use whatever tool you find most convenient. Do not feel you have to use one from this list if you have a favorite you are already using.

The easiest way to provide captions for your talk is to use the auto-generation of captions via YouTube and then correct them.
To do this you will need to upload your talk to YouTube (note: your talk automatically will be considered private).
Guide to uploading your video to YouTube and generating/editing captions:
After uploading to YouTube you can review the automatic captions and make changes, if needed:
- Sign in to YouTube Studio.
- From the left menu, select Subtitles.
- Click the video you want to add captions or subtitles to.
- Click EDIT next to the subtitles you want to edit.
- Review automatic captions and edit or remove any parts that haven't been properly transcribed.
Then you will need to export your captions to a .srt file for submission:
- Sign in to YouTube Studio.
- From the left menu, select Subtitles.
- Click the video you want to download captions or subtitles from.
- Under "Subtitles", click More
next to download subtitles you want to edit.
- Note: You will need to publish them if they have not already been published by clicking PUBLISH
- Choose "Download" (using the arrow; you can choose which format you want to download, .srt is best)
Please open the captions file in a plain text editor, and fix any mistakes from the voice transcriber. Anything that will help the readability of the captions is appreciated; don't stress about it :-)
Naming Conventions for Submitted Talk Materials:
For submission, please name the files with your Family Name and the title of the talk.

- If you can not access this directory (i.e. can't access Google Drive in your location), please let us know and we can work out another option for your submission
- We will give edit permissions to those who have registered for giving a talk using the e-mail that they listed. If you need access, please contact us.
