AkBKukU - Running a DOOM Server on Windows NT Server 4.0 [Part 2]
1,693AkBKukU returns with part 2 of the DOOM server series.
This episode has crazy audio sync issues. Why didn't we fix it? AkBKukU explains below (if you're curious):
I was trying to reduce the screen flicker from the CRT as some people were reporting the video was uncomfortable or painful to watch, so I recorded any clip that had a CRT taking up the whole screen at 30fps to reduce flicker on the final video.
This is the result of the true fix for the 30fps video clips. These are the same shots encoded at different framerates. I had spent some time looking at some of my other projects and some of the video files and I learned a couple things:
- My camera records in 59.94fps not 60fps
- My camera also records in 29.97fps not 30fps
- All of my other videos were correctly set at 59.94fps for the project. (I probably knew the true framerates before but forgot them)
- I had converted the 29.97fps CRT clips into actual 60fps so there was a ~1% difference in speed between those and the native 59.94fps shots.
So taking all that into account, I took the original 29.97fps shot of the CD falling out and re-encoded it to 59.94fps. low and behold, there were no audio sync issues. So now I know in the future I can do mixed framerates. I just have to convert them correctly.
Here is the difference in action: https://www.youtube.com/watch?v=9YGRTFKvDX8
Unfortunately, this changes the number of frames in the video files. I believe that means I can't just swap out the source files in the edited video to fix it. I'd have to re-edit all the "30"fps parts again. Additionally, I would still have to re-encode all of the shots into 59.94fps. All 13GB of it.
There just isn't enough time to do hours of editing and re-encoding since there are other things I need to do. Hope you guys can still enjoy it.
