To ensure a smooth uploading process and the best possible playback quality on your videos, refer to these recommended settings:
- Videos should be recorded at 1080p. 4K is highly recommended as it will give you more space to reframe and zoom in on your footage when editing.
- 16:9 aspect ratio (horizontal) for slides and video.
- Frame rate should be either 24 or 30 frames per second (fps).
- Videos must include an audio track.
- Video bit rate of at least 300 kbits/second (3000-5000 kbits/second is ideal).
- Videos cannot be greater than 2GB in size.
- While the platform accepts .mp4, .mov, and .avi files, we recommend .mp4 for the fastest upload speed without compromising quality.
- Video compression format: H.264
- Audio codec: AAC-LC
If the bitrate on your videos is too low (less than 300 kbits/second) you may run into issues uploading them to your class. To check your video’s bitrate, you can use a free tool like MediaInfo (Mac, Windows) and if you’re using Quicktime, open your file and hit command-I to see a consolidated bitrate. Both programs will give you detailed information about your video's encoded properties.
We recommend re-exporting your videos with a target bit rate of 3000–5000 kbits/second. If you’re unable to re-export your original videos with a higher bit rate, you can also try to re-encode your videos using a free, open-source software called HandBrake. Here’s how:
- Once you have the software installed and open on your computer, select your video via the Source button (or click and drag into HandBrake).
- Then, select and name the Destination for where you’d like the new video to be saved to. You can leave most of the settings on their default.
