Which apple prores should i use
This codec is perfect for environments where storage capacity and data rate are most important. Apple ProRes Proxy's target data rate is approximately 45 Mbps at x and The chart below shows how the Apple ProRes' data rate compares to uncompressed Full HD resolution x bit and bit image sequences at According to the chart, even adopting the highest-quality ProRes formats— Apple ProRes XQ and Apple ProRes , offers significantly lower data usage than that of uncompressed images.
Login Language. Technical Knowledge. The advantages of using Apple ProRes codec in post-production are: Reduced computer workload, thanks to image compression ProRes slightly compresses each frame of the captured video, reducing video data.
Therefore frames are not stored in RGB, in which each letter stands for the intensity of red, green or blue. Frames are stored in YCbCr. Y stands for the luminance and Cb and Cr for the color. It uses the full range of luminance information but compresses the color values. It throws away color information which our eyes hardly notice and retains the luminance information which our eyes are more sensitive too. However the loss of color information is a trade off between size and quality.
This is especially noticeable in color grading. As a signal has more color information to work with than a The ProRes and versions have another key difference.
The maximum amount of bits available to be used. The bit depth is the range of the colors the video is able to use to assign a color per pixel. An 8-bit camera can assign a value up to to Red, Green and Blue.
Until recently 8-bit was the standard for consumer grade cameras, but recent cameras like the GH5 support bit. Going from 8-bit with 16,, possible colors to bit with 1,,, possible colors gives more headroom in post-production and a better dynamic range. So the ProRes Family is divided into 2 sub groups. So if you have to color grade or do VFX work on your shots while re-exporting the footage.
Choosing a HQ version of ProRes will retain the quality better over multiple generations. Your choice for the right ProRes version for you will depend on two things. The balance between the quality you need and the amount of storage. Accept settings Hide notification only Settings. Cookie and Privacy Settings. How we use cookies. Essential Website Cookies.

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 As-a-rule-of-thumb, ProRes is the best choice for video that originates on the computer such as screen captures, Motion projects, After Effects projects, Photoshop sequences or video that requires an alpha channel.
It is a very specialized, high-quality format that is designed for high-end post production workflows and facilities.
