Couple of examples:
Rnd 2 @ 10:07.
First pattern is 4 bars on beat 1 but if I hit my spacebar to pause on the 1 the beat meter is consistently stopping on and of 1.

Unfortunately, my music theory knowledge is almost equal to 0, and it's hard for me to understand what you mean, figroll :(diglet wrote: Sat Oct 07, 2023 7:31 pm I checked in OFS with the audio waveform feature, and it does look like the beatbar is 50ms (3 frames) early, consistently over the entire file.

- Are you able to play 4k 60fps video on youtube?
- What device are you playing this on?
- What video player are you using?
It may be possible that 4k version may be too much for your device, i used codec that can be unplayable on older devices but allows me to cut the file size in half. I would suggest trying 1080p version i just added

You don't notice because the human brain is used to compensate sound coming in later than light. It's always better to have sound come a little after the associated light, but the opposite makes our brains bug.diglet wrote: Sat Oct 07, 2023 7:31 pm I checked in OFS with the audio waveform feature, and it does look like the beatbar is 50ms (3 frames) early, consistently over the entire file.

ffmpeg -i 'Fap Hero - Fantasy Play.mp4' -pix_fmt yuv420p -c:a copy fixed.mp4Normal mode is 2 minutes longer than hard mode? What extra footage does normal have that hard mode doesn't?

Thanks!BlueM00 wrote: Sun Oct 08, 2023 7:53 pm This has incredible production quality. After a few minutes I had to go back and re-read the yellow/blue/purple to understand it properly, but after that it was great.
If I had one critique, it would be that the rhythm-changes were a bit too frequent, so I felt I was spending time watching the beat-bar rather than enjoying the show.
This should keep the audio tracks and will allow you to adjust the quality (-crf - the lower the better. I reccomend setting it to 18). Also you can use libx264 if you want older codec (better performance but lower quality)diglet wrote: Sun Oct 08, 2023 9:24 pm I wasn't able to play this with DeoVR because the pixel format (yuv420p10le) isn't supported. I was able to fix it with this command:
This does slightly degrade video quality and strips the extra audio channels.Code: Select all
