Re: DGNV HDR preview doesn't match DGHDR2SDR results

As a side note, a manual conversion as I wrote in OP didn't give me the same color either, so I might have done it wrong.

Re: 2:3 pulldown – or not?

Can you please clarify this aspect? It's something bit obscure to me. In order to fit anything into a DVD, you have to fake a few things. For example, since video resolution can only be 720x480 for NTSC contents, you have to either resize 848x480 to 720x480 and set DAR back to 16:9, or add black bo...

Re: 2:3 pulldown – or not?

DVD specs only allow 720x480@29.97fps and 720x576@25.0fps (among a few other uncommon options). If the movie is 848x480@23.976fps, it must be converted or flagged to 29.97fps interlace and resize or letterbox to 720x480 to be able to fit into a DVD disc. No exception as long as it's a valid DVD vide...

Re: 7 extra frames on 1 source

Yea occasionally they insert IDRs at some commercials or between programs, it's kinda random. Sometimes it's just full CRAs across multiple programs.

Re: 7 extra frames on 1 source

Yea it happened to TV caps a lot. They use CRAs instead of IDRs as many as possible, so the program can only be cut on CRAs. It's wise to make it work like AVC leading B frames and keep the rest of the video in sync and seek accurate.

Thanks for all the work guys!

Re: DGNV HDR preview doesn't match DGHDR2SDR results

Just a reminder: I could be wrong though. I'm very new to the 4K/8K/2020/HLG world, so I'm still exploring and trial and error.
