WebM or MP4?
WebM uses open codecs and is great for web pages. MP4 with H.264 is more widely supported by software and hardware, so it's the safer choice for sharing and editing.
Expect a larger file
VP9 and AV1, the codecs inside most WebM files, compress better than H.264, so the MP4 can come out bigger. Use Compress Video afterwards if you need it smaller.
