I often do QuickTime screen recordings of slideshow presentations (e.g. Keynote).
These videos are 1080p 60fps and mostly text. They can go for minutes at a time with the same exact frame on-screen (static slide) yet have 60fps transitions between slides.
What are some compression tools or techniques that work best for this kind of video? I’m looking for something that keeps the text sharp while maintaining the 60fps animation transitions, without the file size being insane.
I’m not looking for answers like “use the Export for 1080p menu in QuickTime”. The best answer will have a solution that’s customized for the specific needs of a slideshow presentation video, perhaps using variable frame rate compression techniques.
-tune stillimageis, strictly speaking, meant for one static image for the span of the video, and will impact the slide turnover parts if those aren't simple cuts. And in my experience, I've gotten smaller files without it.
