Full Version: How to remove the "original frame rate" tag?
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Some episodes of the Simpsons have a tag for "original frame rate" in the DVD file which is carried over into the Hybrid output file.
This is causing issues on my Roku when the actual frame rate is different than the original frame rate.

Is there an option in Hybrid to not include the tag for original frame rate in mkv?

It looks like this in MediaInfo
Code:
Frame rate                               : 29.970 (30000/1001) FPS
Original frame rate                      : 23.976 (24000/1001) FPS
Original frame rate is the frame rate in the video stream.
(MediaInfo: 'Frame rate' <> frame rate signaled by the container, 'Original frame rate' <> frame rate signaled by the stream itself)
To get rid of it (by changing it to the container fps, while keeping the container fps) one would have to change the bit stream.
Hybrid does not support changing the bit stream on remuxing.
You could remux the file using ffmpeg and use it's bitstream filter (https://ffmpeg.org/ffmpeg-bitstream-filters.html).

So when I apply the setting 'scale output frame rate' under speed settings to 29.97 it's not actually changing the video frame rate, it's just a container flag?

No, that only works when reencoding, and then the frame rate of the stream should change.
If it does not that's a bug.

Since you didn't really share any details on what you are doing I'm just guessing what is happening.
-> share proper details if you want a better assessment. Smile

Actually this might have been fixed. 

The problem file was processed on Hybrid 2021.12.10.1

I just ran it again on Hybrid 2022.03.20.1 and the flag is no longer there.
Okay, so I consider the problem 'solved by updating'. Big Grin
