Thanks alot for your help to do in shadow files. I will do that in the 80% stoppage projects to see whether it helps or solve the problem. will report it here.
Observation. when I do upload and work on the 100 fukles| project at the same time, it is very slow. Stoppage all the way 10%, 20% etc. Dont have other program running while you work on large project. Memory check from Task manager seems ok, about 4GB used out of 16GB. available.
If you haven't done so already, please submit a technical support ticket for your issue and then respond with your ticket number so we can pass it on to CL customer service. This will help they duplicate this issue in the lab and then fix.
Hank123: You were asked a few times to generate your DXDiag file. You can find the info here to generate it. CL customer service will require it.
Elfgren: Tack så mycket for the excellent video. We passed it on to CS customer service.
That's really something! I see the same behavior on an Overlap transition when the two clips are part of a long chain, and the problem occurs when I drag the either the starting or trailing edge left or right. In other words, any attempt at changing the transition's length by dragging an edge will cause the long delay.
That tool will let you set any value without triggering the delay.
I've also found that the farther to the right on the timeline the transition is, the less it is affected by the delay. Since the delay is also affected by changing which track the clips are on, this strongly suggests that the number of clips that need to be shifted in that track is a big factor.
Near the end of the timeline, only a few clips would be affected by changing the length of an Overlap transition, but near the beginning, almost all the clips are affected so the delay is many times longer. Putting a single clip 5 hours out on the timeline doesn't seem to affect the delay, so the number of clips that are affected seems to be the main factor when the delay occurs.
