YV12 input hevc encoding also no hdr flag
Staxrip question
When i select the h265 Nvidia encoder the input color space is always yv12. I am new to this and if someone would be kind enough to let me know if this is ok for my use. It appears to signify 4:2:0 in what i can find online. I am encoding my blu rays and my uhd blurays with a turing nvidia card into h265 hevc. From what I can tell everything appears ok on the finished product. AVS automatic changed to ffvideosource once i load my media. Should i be on the look out for anything particular on my media when using this input yv12? Also I have updated staxrip and there is no longer a hdr flag in the h265 nvidia selections, is this an issue? Thank you for any wisdom shared |

Yet it appears to be a 10 bit input to 10 bit out, is this correct? AS I know little of the source filters I have been unsure on which one to select so it has been left on automatic. |
