Hi Chris,
Here there is some specific information about H264 enoding:
https://trac.ffmpeg.org/wiki/Encode/H.264#LosslessH.264
Essentially you can try with something like -crf 18 or even lower... As
explained the scale is from 0 (best) to 51 (worst)
Hope this helps.
Lorenzo.
Can you clarify with numbers? Small in
resolution or just small in size?
Small in size. At te moment its images only (no
audio). For 125 images,
making 125 frames, played at an fps of 25 per second (i.e. 5 seconds)
the video is 420K. OK, if ffmpeg does a good encoding job, in the way
you describe, the quality could be just as good as the images allow.
