Content change from 60FPS to 58FPS after convertion - Orion3000 - 08.01.2023
Hey bro I have an issue and I hope you can help me with it. So I have multiple 1920X1080 16:9 videos that are AV1 and they are 60FPS. I use NVENC and set constant bit rate HQ and set the bit rate to 10000k and use h265 or even h264 or even leave it AV1 but no matter what the result is 58FPS instead of 60FPS.
Interlace is disabled and I'm not using any filters or anything simply changing the codec and reducing the bit rate. Everything else is default options from when I installed the program. My question is is there anything I need to disable or change to fix this? Thank you in advance.

Without a debug output (read the sticky) and any real details, I can only suspect what is happening.
So my guess is that your source if vfr input and the time codes get either ignored in the process or they are not ignored but the first or a few entries in them get fixed and that causes the average frame rate to change.
-> share a debug output, then I can look at that and see what's happening.

Here is a zip file containing the debug as you requested.

....Time codes jump per frame between 16ms and 17ms per frame, so the frame rate is between 1000/16=62.5 and 58,82.. fps.
1000/60 is 16.66.. ms per frame, which would fit, Hybrid did calculate the average frame rate and reported:
[quote]Current frame rate: 59.944 differs from average time code frame rate: 23.976.
This will be ignored since 'Check average fps of mkv/mp4 files' is disabled.[/code]
If 'Config->Automation->Matroska Settings->Adjust fps to average fps' were enabled, Hybrid would have changed the fps to 59.944fps.
So not 60fps. (Side note: you might to work over your process to create these files, so that they are not vfr and are flagged properly.)
To fix the fps indicated in the video stream, you could:
- enabled 'Filtering->Speed Change->Speed Settings->Change speed' and set it to 60 fps
Since the time codes seem to match, 60fps with not 'bumps', you could also:
- enable 'Filtering->Internals->Handling->Ignore all input time codes', this will cause Hybrid to ignore the time codes and simply detect the source as 23.976 fps as indicated by the video streams and then,
- enabled 'Filtering->Speed Change->Speed Settings->Change speed' and set it to 60 fps

RE: Content change from 60FPS to 58FPS after convertion - Orion3000 - 08.01.2023
I will do as you suggested. Yes I did upload the correct video debug. I notice the mediainfo report the same thing on mine which is strange because the video is really 1920x1080 and it is 60FPS. I will use the options mentioned by you and will let you know how it will turn out. Thank you so much for getting back to me with a possible fix.
