Copy metadata to new file

[Valdiralita]

Hey everyone!

Im re-encoding a H265 10bit HDR clip.
After encoding it seems that in the generated file there is missing some metadata.
Is it possible to copy that from the original file to the new one?

Do you want it copied even if it isn't applicable to the destination file?

Unfortunately ffmpeg with the

Code: Select all

map_metadata

does not produce the expected result, even with the flag

Code: Select all

-movflags use_metadata_tags

the missing tags are not in the output file.

Why do you think its not applicable?

That would be for you to compare the MediaInfo for the original and the encode. Metadata is generated fresh for every encode, and obscures old metadata, although not its collateral.

So things like whitepoint and min/max luminance change during encode and are not needed?

You can set it manually in the "additional options" textfield (can't remember the exact syntax). The main issue is that HandBrake pipeline is 8bit, so the video will lose a lot of precision when transcoding it with HandBrake.

Oh, actually that explains a lot! Thanks for the info.
