How to determine how many bits are in the original video 8 or 10?

BDRip 1920x1080 x264 hi10p FLAC Here’s what’s written on the source. If it’s 10 bits, then the old Shotcut, which is installed on Windows 7, will be able to export in 10 bits? I haven’t seen such a signature anywhere in it, but who mentioned here that the ProRes codec only exports in 10 bits.

Properties > Video > Format
There can be a lot of different values as seen in FFmpeg API docs.

But the most common 10-bit format is yuv420p10le, and ProRes is typically yuv422p10le or yuv444p10le. In fact, if you choose an Export Preset in the ten_bit category and look in the Other tab, you can see them being used.

I didn’t understand anything in the documentation. I have yuv420p10le, do I need to select a codec that exports in this format or do I need to register the setting? Or is there no difference, can I choose any codec that supports 10 bits?

I do not know what you need. It is not necessary to export 10-bit if the input is 8-bit. You can mix 8- and 10-bit video in a project and export in either. Keep in mind that 10-bit H.264 is not very compatible with devices, but it is very common in HEVC and AV1 (where available).

There is no need to do this at all, as it will simply append zeros to the number. The information will remain the same, but it will take up more space. I wanted to understand is this part “yuv420” important when choosing codecs? Or should I only pay attention to this “p10le”? I want to export in the highest possible quality. Based on your previous answer, I assume that I just need to choose any codec that supports 10 bits. In the old version of shortcut, it is only ProRes?

Why have they started mentioning this AV1 codec lately? What is the point of it? If you had agreed with YouTube that with certain settings nothing was recoded there, but everything was left as is, then there would have been some point.

I exported with ProRes codec. Color rendering “НД”. What will “НД” affect? ​​I installed gop 4. Shortcut is an old version.
