![]() ProRes is a DCT scalar 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 and are also intended to be used as intermediate codecs. The benefit of an intermediate codec is that it offers excellent random access performance in post-production applications, and retains higher quality than end-user codecs while still requiring much less expensive disk systems compared to uncompressed video. ![]() This is achieved by only using intra-frame compression, where each frame is stored independently and can be decoded with no dependencies on other frames. ProRes is a line of intermediate codecs, which means they are intended for use during video editing, and not for practical end-user viewing.
