When I convert a video with ffmpeg, and use mediaInfo to review the metadata, I see the followings for the video codec:

Format : AVC 
Format/Info : Advanced Video Codec 
Format profile : Baseline@L3.1 
Format settings : 1 Ref Frames

Whereas for some other videos, mediaInfo shows this:

Format : AVC 
Format/Info : Advanced Video Codec 
Format profile : High@L4.2 
Format settings : CABAC / 4 Ref Frames

What are the differences between these two profiles and settings? Do they have any effects on the compression ratio/file sizes? Any pros/cons? My goal is to reduce the video file sizes at much as possible with negligible quality degradation.

    More ref frames = better compression. Higher profile = better compression.

    How about quality? Encoding execution time?
