Lossless H.264 video: ffmpeg -hide_banner \ The capture file will be largish (around 20MB per minute), and will require some further encoding once the capture/editing is completed to reduce the file sizes. It is also one of the best supported codecs for compatibility. Of the lossless codecs tested it had the best combination of file size (way smaller than HuffYUV) and speed (can mostly keep up with the capture even on my old laptop). Some quick testing suggests H.264 in lossless mode seems to be the the best option. The aim here is to capture at the highest quality possible with minimal CPU usage (so that the capture can keep up without dropping frames, and to leave some head room for other processes). Verify that the compressed versions are good, and if so, delete the original captures to save some disk space.These files can be uploaded to echo360 if needed - they accept these formats.
