This seems to have helped.

Other symptoms. Usually before this happens, the playback and scrolling get laggy. Sometimes it recovers, then other times it does the above. After moving to draft, it still does that, but not as bad. (Important to note, it isn't the clips as it won't do it consistantly for the same clip and will 100% be different between application restarts). But after switching to draft, it seems have helped. When the lag starts, its less, and so far for the last 30 minutes of working on it, it hasn't locked up once.

FYI - system resources were never even close to max when this issue happens.

@joshua-noesser I had no issues with a few VP22 build versions back half a year or so, but I just experianced the same issue with VP22 b250: a few clips on timeline, no editing done yet on them, just playing them and I see the memory go up to 5 GB (out of my 64GB) until the end of last clip, memory leak?

Anyway, I had several no responding hangs, even after restarting. This should not happen, not if you haven't even started with the real editing (cutting/ pan crop, zoom, plug ins, audio and video enhancement, text etc...)

Yup same

FYI - I am still getting lagging, just not the full unresponsive. Hopefully someone knows what's going on here as it seems to be only v250

I'm not experiencing slow playback or hazy screens but when moving clips it takes about 2sec to grab the clip and start moving. It moves OK when it starts to move. Just loaded the same clips into V21 and dragging clips is instant, so it looks like there is an issue with V22 250 that needs looking at?

I find when loading a few clips everything is fast no lag but after editing for a while - adding FX levels/stabilisation/fades etc the lag appears.

I would be grateful for some advice on this. The issue I am having is as above, as I edit a project - only using a few FX and fades I get increasing lag when moving clips on the time line. My current project is about 17 min in length. The media is Sony AX700 XAVCS 4K. I have about 15 clips to do (all on the timeline) and the lag is now about 3 sec for the clip to move after grabbing it with the mouse. Everything else is fine - play back, opening FX, grabbing the timeline bar to expand/contact/move the timeline. Media and Vegas are on different gen 4 NVMe drives at 7000mb/s, RAM is 96GB. This is not a V22 250 issue as I can copy and paste the project into both V21 and V20 with the same lag issue. I have a couple of other recent projects which show the same lag and also a very recent one 9 min in length, same media, same FX where there is no lag - very strange. I need to somehow bottom out why this is and what is the reason. Many thanks.

I think I found the culprit - RX10 Spectral Denoise. When removing this sound Fx (I had about 10 or so clips where I used this to remove wind noise) the lag got less and when all removed the lag has gone.

When you say "removed", do you mean deleting the RX10 or just unchecking the box. I'll use FX, playback (or even render) the clip, and if it is what I want, disable the FX until I am finished editing. But for the most part, my computer has enough "horsepower" to get really decent playback frame rates with different Preview settings.

Your computer should also have no issues. Is the RX10 Denoise optimized in any way to make use of your GPU?

I find this: above 13 clips the lag is 3 sec or more, above 5 clips the lag is 1.5 sec, 3 clips it is 0.5sec, 1 clip is no lag.

If you just deselect the FX the lag remains, it must be removed and project saved.

It does not seem to use the GPU and looking at settings there is no option for it. It has a setting to enable multicore which I have enabled. The documentation indicates that spectral denoise uses a lot of memory and cpu power while voice denoise is much less intensive (and less effective in my experience).

Reyfox do you have RX10 Spectral denoise to try?

In Vegas, besides the timeline lag, saves take longer and cut takes longer. the lag is only on timeline clip movement and not in preview playback.

@andyrpsmith sorry, I don't have RX10 Spectral. I rarely have to do anything to the sound of what I record. I also use a lot of music, so while I might have "ambient" sound from clips, Smartsound or the Hub music is what is in my videos.

As for fx, I'll use a combination of Boris Continuum, NBFX TotalFX and Vegas native. I constantly monitor hardware usage with Task Manage open on my second monitor. I do a lot of incremental saves using the keyboard shortcut, and saving is quick. But my projects are not usually longer than 10 minutes. Everything is 4K and a lot of images with pan/zoom from @jetdv's Montage and Event Pan/Crop. The footage is from my Panasonic cameras, which are easy for Vegas to handle.

Many thanks for your replies. At least I now know the reason for the lag.

No problem! I know that there are some plugins that cause Vegas to crawl on it's knees begging for relief.
