The target data rate of Apple ProRes is approximately Mbps at x and Sure enough, ProRes HQ is the most popular ProRes flavor with widespread adoption across the video post-production industry as it supports full-width, video sources at bit pixel depths, while remaining visually lossless through many generations of decoding and reencoding. This is the ideal format to use with the GH4 , for instance, as it supports bit color subsampling. ProRes features full-resolution, mastering quality RGBA color and visual fidelity that is perceptually indistinguishable from the original material as it provides a colour sample for each pixel.
Apple ProRes is a high-quality solution for storing and exchanging motion graphics and composites, lossless alpha channel up to 16 bits. The target data rate of ProRes is approximately Mbps for sources at x and Was your footage shot on a DSLR with no need for alpha transparency?
Apple has posted an excellent white paper PDF link which is what I referred back to when writing this blog post. On top of that, BMCUser has a very helpful chart to show you anticipated recording times in ProRes depending on your frame rate and resolution.
It's worth noting that nearly every external recorder on the market currently allows you to choose not only ProRes as your codec, but the specific type to use for recording. I doubt anyone working outside of very large theatrical or television productions would need this, but it is nice to know it's in the hands of consumers. The most obvious types of footage to use in this circumstance would be anything shot against a green screen.
ProRes HQ — Same as above basically without the alpha channel. Your camera's internal codec will have a compressed data rate of anywhere from 20Mbps to 70mbps usually variable. ProRes LT aims for Mbps, which still looks great if you're getting a sensor readout over HDMI and will serve you much better in post, especially while color grading. ProRes Proxy — I would never shoot directly to this format as it's for cutting dailies or doing offline editing—it's something you generate in your NLE or before the edit to make life easier.
Definitely not recommended as a start-to-finish solution. The target data rate is approximately Mbps at x and Apple ProRes is a high-quality compressed codec offering nearly all the benefits of Apple ProRes HQ, but at 66 percent of the data rate for even better multistream, real-time editing performance.
Apple ProRes LT is a more highly compressed codec than Apple ProRes , with roughly 70 percent of the data rate and 30 percent smaller file sizes. This codec is perfect for environments where storage capacity and data rate are at a premium. Apple ProRes Proxy is an even more highly compressed codec than Apple ProRes LT, intended for use in offline workflows that require low data rates but full-resolution video.
The target data rate is approximately 45 Mbps at x and They are also the only Apple ProRes codecs that support alpha channels. About Apple ProRes Apple ProRes codecs provide an unparalleled combination of multistream, real-time editing performance, impressive image quality, and reduced storage rates. Apple ProRes Apple ProRes is a high-quality compressed codec offering nearly all the benefits of Apple ProRes HQ, but at 66 percent of the data rate for even better multistream, real-time editing performance.
