RE: different frame counts in the source and in the destination file - kingcrimsonster - 01.03.2024

Not for all files this bug.
Please download the source file from my first post

RE: different frame counts in the source and in the destination file - Selur - 01.03.2024

I did and I used that as source for all the encodes,....
"C:\Users\Selur\Desktop\source.avi" is where I downloaded it too,...
by the partial output of mediainfo you posted:

Frame count : 448
Source frame count : 445

it seems like the container somehow indicates more frames,...
Does this also happen, if you ignore the audio?

RE: different frame counts in the source and in the destination file - Selur - 01.03.2024

My guess this is a mess-up of mediainfo.

Same result...

RE: different frame counts in the source and in the destination file - Selur - 01.03.2024

Since you didn't post the whole mediainfo output: You didn't mix up Video&Audio frames, right?
