We have a source that produces groups of JPEG images that are 352x240 and ~10K in size. There are pretty close to 3000 for a 10 minute interval.
When I encode as follows: ffmpeg -framerate 5 -i %05d-capture.jpg -codec copy output.mp4 I get a video that works as expected, its ~10 minutes long and the images transition like they should. With some of my attempts to encode with compression, the output becomes composed of segments which simply stall as if it were skipping frames, whereas the following seems like a start: ffmpeg -framerate 5 -i %05d-capture.jpg -c:v libx264 -preset veryfast output.mp4 however it takes too long. I have over a dozen groups of images appearing every 10 minutes and I already use a message passing cluster to offload encoding onto multiple hosts. Is there a more applicable scheme for use with JPEG images of this size or a better route to take in general?
