![]() The 4444 codecs additionally have dynamic range limits (see Notes). The 422 codecs are differentiated primarily by data rate limits, expected file size ranges and software version support. The Apple ProRes codecs, both the 4 families, support both interlaced and progressive scanned images and preserve the scanning method used in the source material. While ProRes is a 10-bit native codec, it can be used with either 8- or 10-bit sources and 8-bit sources (such as DVCProHD) would need to be upsampled to a 10-bit file. any frame size (including SD, HD, 2K, 4K, and 5K) at full resolution,.4:2:2 source material (as well as 4:2:1 and 4:2:0 source material if the chroma is upsampled to 4:2:2 prior to encoding),.The key character traits that define the ProRes 422 family are support for: ProRes was designed to be a high quality intermediate codec that keeps post-production workflow data at 10-bit quality, with a bandwidth low enough to be usable for the majority of FCP users. See Uncompressed YCbCr Video Picture Stream Family (4:2:2) for more information on 4:2:2 data. b: number of (additional) chrominance samples (Cr, Cb) in the second row of J pixels.a: number of chrominance samples (Cr, Cb) in the first row of J pixels.J: horizontal sampling reference (width of the conceptual region).As explained in the Wikipedia article Chroma subsampling, the ratio describes the number of luma and chroma samples "in a conceptual region that is J pixels wide, and 2 pixels high." The three key parts of the ratio are as follows, omitting the alpha channel: Chroma subsampling is usually expressed as a three-part ratio (4:2:2 in the case of ProRes422) although it may also include a fourth part (e.g., 4:4:4:4), when alpha or transparency data is part of the stream as is the case for ProRes4444. The three digits in the name represent the chroma values. There are two main branches of Apple ProRes: the Apple ProRes 422 Codec Family (described here) and the Apple ProRes 4444 Codec Family. Short name: Apple_ProRes_422_Codec_FamilyĪpple ProRes is a family of proprietary, lossy compressed, high quality video intermediate codecs primarily supported by the Final Cut Pro (FCP) suite of post-production and editing software programs.If you just want to shoot great-looking video straight from the phone and don't intend to play around with color grading in post-production software, then you likely won't see much benefit from using ProRes. Keep in mind, though, that file sizes are immense - a 1-minute ProRes 4K video file is 6GB, while a 1-minute video in regular 4K is around 200MB.Īpple has limited ProRes recording to only 1080p instead of 4K on the lowest capacity iPhone models, but even if you have lots of room it's worth using it only when needed to avoid filling up your storage too quickly. If you really want to squeeze every ounce of quality from the iPhone's video and plan on doing a lot of post-production, then you might benefit from ProRes. Simply press Record and you'll be shooting video in ProRes format. ![]() ![]() Tapping it will activate ProRes and the white line will be removed. If it has a white line through it, then ProRes is turned off. Now when you go into your camera and select video, you'll see a new icon saying ProRes. Tap it so that the toggle shows as green. In that section, tap Formats and in that subfolder you'll find an option to turn on Apple ProRes video capture. If you're running iOS 15.1, head into Settings and scroll down to go into your camera settings. To do so, head to Settings > General > Software Update to ensure you have the latest version. Apple brought ProRes to the iPhone 13 Pro with software version 15.1, so make sure you've updated your phone to this version. ProRes is frequently used in professional video productions, but Apple has now made it available on the most recent iPhone.įirst of all, make sure you have the latest version of iOS installed. ProRes is Apple's own video codec that allows the camera to capture more information when shooting and thereby allowing for greater control in post-production in software like Adobe Premiere, Final Cut or DaVinci Resolve. But the arrival of ProRes video can help take that even further. Apple's iPhone 13 Pro can already shoot superb-looking video with rich colors and tons of detail, thanks to its 4K resolution.
