Can anyone provide me a screenshot or picture of what it looks like when the RPU doesn't match the HDR10(+) stream?
I'm both curious and looking for a reference as I think I'm having trouble lining up an RPU with the HDR10+ stream.
I'm in the process of adding Dolby Vision to an existing HDR10+ stream (Ford v Ferrari by WilDCAT). Assuming both would be the same, I got the following message:
Warning: mismatched lengths. video 219511, RPU 219471
Metadata will be duplicated at the end to match video length
I let the process finish and watched with my C2s internal player (M2TS, DV logo triggers) and saw nothing out of the ordinary.
After a bit of comparing between the files, it turns out the HDR10+ starts 40 black frames earlier than the RPU I have.
I delayed the RPU by 40 frames with this JSON:
Code: Select all
{
"duplicate": [
{
"source": 1,
"offset": 1,
"length": 40
}
]
}
However, when playing it with my C2s internal player, I'm not seeing any difference between this and the previous file when it was 100% misaligned by 40 frames. Did my version of Dovi Tools (2.0.2) automatically align the two the first time I injected the RPU or am I doing something wrong?
P.S.: I do not have Windows (I have Linux) so I'm using the old-skool method of manually creating a JSON and injecting that into the RPU instead of working with the more user friendly DoVi Scripts workflow.
