Hi folks Just to throw a further spanner in the works, this may be well known, but it's worth saying anyway. There's a pretty large difference between compiling "ffmpeg" and the "ffmpeg" that you will get from, say, a website that offers a binary. The very basic core of ffmpeg is probably not

The ProRes implementation is not likely to be perfect in terms of Apple's internal spec. They do not publish the spec so we don't know. In general, it has been shown to be reasonably reliable when used with most software decoders. It has had problems in the past (I haven't checked for years)
