Hi guys, not sure if I'm in the right forum, move me if I'm not.

 

I've got this problem going on for a couple of months now, and now finally it's starting to annoy me so hard, I asking for help.

The problem I have is, when I'm making Rocksmith 2014 Playthroughs, I record the same song 3 times, (every arrangement) and then I sync up those 3 to have the splitscreen video

Like this: 

This worked for like years, and now lately something is fucking up.

I'm not sure it's Rocksmith or Vegas Pro or my computer or my graphics card or ...

 

Here is the actual problem with screenshots:

1)  Syncing with video frames

This is to get the best sync possible for the video frames, the audio can get synced up better later on

2) Syncing with video frames

Here you see the smallest step I can drag the middle video track, it goes per frame, the audio is still locked to the video track

3) Syncing the audio

Here I ungrouped the audio and video, (they turn red then) I zoom way in and then sync up the audio waves with a ruler

4) Song goes out of sync

This screenshot is a little bit further into the song, and check out the third bass track, the beat is out of sync for some reason

 

So somehow the third track got 0,001s out of sync, problem with graphics card? audio card? Fraps?

It's very annoying, cause those little differences in soundwaves create reverb effects and change alot in sound and volume, believe me

 

Anyone knows what is happening and how I can fix it?

Here is a screenshot of the end result, around 15 cuts and resyncs needed to make it sound good again.

As you cant just stretch out audio tracks, it makes it sound weird.

So I gotta cut them up, at the point where it 'shifts', this is clearly hearable, from where it is perfect sync to where it is somewhat 0,001s delayed.

I cut it up and then resync all 3 parts again. But if I cut it wrong, a bit to early or to late, then you can hear a very short missounding part.

So if I can fix this any other way that would be nice.

Maybe it's a setting in Fraps? will reinstall help?

 

Oh maybe some techical info helps?

I have recently moved to Windows10 and my laptop only has an SSD-card of 256GB, which is most of the time 200GB full
