This means that each frame of a video is compressed individually, and this compressed frame is sent to the display unit during the playback or for the post-production process.
Because of this, unlike the latter two compression types that give overhead to the GPU during playback and editing, ProRes clips allow maximum utilization of hardware resources as no processing is required to decompress the videos when they are opened in a post-production tool or media player. ProRes significantly compressed the RAW footages while retaining the detailed information they contained, thus keeping the picture quality intact.Īlthough ProRes compresses the RAW videos, these files are still larger than those compressed with other codecs like H.264 or H.265. The reason why Apple ProRes was developed was the flaws and delays that post-production processes caused. Post its inception, the codec has been available in all the versions of the application that Apple rolled out. ProRes was first released in the year 2007 by Apple along with Final Cut Studio 2. 10 Important Things about ProRes You Should Know using high compression codec mentioned above.Īt the time of this writing, the members of the Apple ProRes family (in ascending order) are ProRes 422 Proxy, ProRes 422 LT, ProRes 422, ProRes 422 HQ, ProRes 4444, and ProRes 4444 XQ. After they are fine-tuned as required, the final videos are exported back to a globally recognizable format such as MP4, M4V, etc. Therefore, to make things work smoothly, these clips are transcoded to ProRes. However, such clips might put overhead on the GPU and the processor during playback or editing using any post-production tool like Final Cut Pro X, Adobe Premiere Pro, etc. If a video has been recorded using any other compression-oriented codec such as H.264, H.265, etc., the file size maybe even lesser. ProRes is a codec that compresses RAW footages in a way that the file size is significantly reduced, but the picture quality remains nearly lossless.
That said, here are ten important things about ProRes that you may not be aware of, but you should if you are looking forward to making a career in film editing. Your computer meets the minimum, if not recommended, hardware requirements. Although the footages compressed using Apple ProRes are large and occupy more disk space, they allow flawless video editing experience as long as the program you are using is good enough. ProRes is one of the most preferred and used codecs in post-production environments.
