I often create long screen-recordings of myself explaining code.

When scrolling text, the movement must be smooth enough. When static, the edges of text must be crisp for legibility.

I tried using CRF (Constant Rate Factor) but the trade-off space does not get me the size compression I believe is possible.

I'd be particularly interested in an encoder that could be "motion-aware". e.g. if the video is static, don't store any information. But if there is movement in the video, start storing frames etc. There is a freeze filter in the new version, but it looks like its for notifications only.

Does anyone have any good encoders (or settings) they can recommend?

Thanks

    maybe turn up the detail and turn down the frame rate, using variable bit rate for the video would help too. I don't know which options that is. – Jasen Jul 31 '19 at 05:38

    See duplicate, particularly the part about CRF encoding. Use a higher CRF to save space. About the stillimage tune, it would usually be used to reduce deblocking filtering, but for screencasts you may actually not want to use that. You have to experiment a bit. – slhck Jul 31 '19 at 10:48
