I've got a series of videos that I'm looking to drastically reduce in size. The video content is very simple: text animating on white background with a voice track on top. The text is mostly just subtitles and occasionally an image pops up, sort of like a PowerPoint/Keynote presentation, and it needs to play on iPad at Retina resolution.
In terms of size, here's an example of one of the video files:
- Size: 20 MB
- Dimensions: 1920 x 1080
- Duration: 5 minutes, 18 seconds
- Codecs: H.264, AAC
- Color profile: HD (1-1-1)
- Audio channels: 2
- FPS: 25
If there were a video format with variable frame rate, that would be ideal because so much of the video holds a constant frame for a second or so (like a PowerPoint/Keynote presentation).
The reason is to reduce download size of a video-intensive app.
