ProRes 422 is a DCT-based intra-frame-only codec and is therefore simpler to decode than distribution-oriented formats like H.264. ![]() It is comparable to Avid’s DNxHD codec or CineForm which offer similar bitrates which are also intended to be used as intermediate codecs. The benefit of an intermediate codec is that it retains higher quality than end-user codecs while still requiring much less expensive disk systems compared to uncompressed video.
