For the .mp4 use the h.264 codec – Details
For the .webm format there’s 2 codecs to choose from VP8 and VP9. The most promising results have come from dropping the quality from 50 down to 15.
And as far choosing which codec, each has proven itself in different situations. The VP8 provides a smaller file size but does appear to be the first one that looks slightly degraded. It was ideal for the drone footage as the VP9 one was very jittery.
Optimal .webm render settings: 1280×720, 15 Quality, VP8 codec, no audio
