How can use this code to encode video?

When 407 and 709 are uploaded to Youtube they have the same (wrong) contrast.

Download the videos from Youtube and play them locally. I think you'll find the contrast is fine.

I check the contrast from the downloaded videos.

If your wish is to use a different color space for h.264 then x264 VUI need to be also modified - replace 709 by bt470bg i.e. colorprim=bt470bg:transfer=bt470bg:colormatrix=bt4 70bg , side to this you may wish to disable VUI signalization for full quantization range - currently this is: fullrange=on where it can be: fullrange=off for 16-235 luma sample values and 16 - 240 chroma sample values.

This worked !

Same contrast and colours when it's upload to Youtube !
