Hey guys, based on this:
it seems there is some way to set the compression level when using
pngenc (-vcodec png). I can't seem to figure out how to do it though.
I tried -compression_level, but that doesn't seem to be doing what I
expect. It has an effect on the result but its always far larger than
My source is 84 frames of uncompressed tiffs which are 222 MB in size
altogether. With compression level 0 my mov file is 534 MB, and with
level 9 it is 275 MB. In either case it's much larger than the
uncompressed frames! Something not right...
Thanks for the help!
