Since the typical human eye is more sensitive to luminosity than color, the two color channels U and V can be given reduced bandwidth compared to the luminosity channel Y while maintaining a certain level of overall quality.

Rgb uncompressed is 8 bits per color, r, g, and b for a total of bits per pixel. Lossless codec. It's complicated, but getting better. Realistically, raw from a camera comes in many different formats - Alexa, red, Canon, etc etc. Most movie companies keep the original for archiving. They usually ingest into the video editor and have everything converted into 1 standard can vary depending on the company. Then edit from there until final output. For home users, the very minor compression of any consumer lossless codec vs dnxhd is nearly insignificant and undetectable, so the better compression, editability, and long term compatibility is worth it.
That said, if you're not going to be around , no point worrying too much about the codec - as long as you have 1 Windows 10 pc working, you can convert from what you use now to any other more modern format before the codec support disappears.
I'd still convert to dnxhd, but really up to you. If you were keeping everything in the original yuv source and adding all edits, stabilization, effects in 1 video editing program, no need to worry because it'll only apply everything at once during the final render. But pushing video through many programs, always best to use In any case, if you use anything less, it'll still be upsampled to internally by most top video editing programs. So I made a compression of a similar file as the one mentioned in the first post this time it's the most recent export of the completed movie with libxrgb, all else being equal, and the size of the resulting file is about three times as high as that of the YUV compressions : 6.
While the encoding time was about twice as high : 0. Is this to be expected? And why would it be so much slower to encode? Rgb bigger than yuv Without knowing exactly what's the conversion process and command into each format, who knows why one is much bigger. Avid not only does broadcast tv, but major films, too, so it needs a solution for all that footage. Not rocket science, but everyone runs to Avid in Hollywood because it just works. If you wanted to benefit from far faster h.
The slower encodes suggest two things - cpu and drive are bottlenecks. If you're using a basic , p h. Higher cards go faster. Hardware encoding acceleration has been around forever. Since Quicksync landed in Intel cpu's 8 generations ago, nvidia since at least the series from Nothing new.
People use them for many things besides games - ai, image recognition, bitcoin mining, etc - because the gpu cards are good at doing lots of repetitive calculations quick. It's all about time vs money. You want to wait, you can even program a scientific calculator to do encodes that take a year. It's possible to max out a hard drive using gpu encoding.
Let's say a 50GB bluray using gpu encodes 4x faster than real time, 30 minutes. No idea about the time differences. Would just chalk it up to the different encoders. As for file size, crf is the factor - it's letting the computer pick a bitrate by magic.
The way to test encoder performance would be to lock the bitrate based on the chroma encoding. So let's say you assign a fixed video bitrate of 10, kbps for those encodes. Encode and time. There's plenty of misinformation in the discussion Originally Posted by abolibibelot.
