I already tried that. I tried in a project with a very long clip which I splitted many dozens of times while playbacking, then back to start, playbacking again while clicking and deleting events. And I did same for a project with many shorter clips in it. When splitting or deleting there are occasional hick-ups where the preview freezes for one or several seconds but then it just goes on. It did not yet find the missing link yet. But often that's the way it is, most issues are not reproducable on all systems and for all kind of projects. That can make it so hard to find the fix.

Try again in a row.
30 clips and delete. If you can delete them all, try another 60 clips. Even more. The more, the faster the error appears.

If you do it twice and you're lucky, it's not a test.

Thanks a lot

Use different files. Not just the one you cut.

I already tried this so often in many variations in the last few years …

Just accept it may not be reproducable on every system and I meanwhile only have one to use.

If maybe the use of certain media could cause the issue it would be very helpful if one could share a sample project with the media included.

I understand.
I'm trying it out right now and it's working. Damn!

Update:

I used a combination of MTS 50fps and DJI 50fps
It freezes every time.

The events in the Timeline reach a total length of 33 minutes.

I have this issue a LOT. Don't even have to delete clips - just splitting while playing causes it. I never had this issue in VP 14 or earlier ( I have been using since VP8 ) Only after I upgraded to 17 last year, and it happens on all my PCs with completely different hardware.

I now have my auto save set to every 30 seconds now because of this. It hangs, and it hangs. I have let it sit a few hours one time hoping it would recover while I ran some errands.

It crashes, or fades out and crashes. Windows asks me to end the task so I do. An error reporting window NEVER shows up for this.

I am still working out my own bugs with VP18 so far and have not tried to reproduce it, but not thrilled to see this is still a problem.

To those who can repro this bug: Have you tried setting the video event's thumbnail view to either "None" or "Head & Tail" only in Options/Preferences/Video? Best would be to set it to "None" for some tests.

Now I'm doing a test - I turn everything I can on and off.
Now I'm at the thumbnail view, and if I disable them, Vegas will freeze immediately when the event is first deleted.

Hold on, people. I'm testing!

It seems that the only thing that really works is this ....


Change the settings and restart Vegas

the problem will probably be in the thumbnail display area.
Try it and let me know.

Update:
Nothing works.
It works great for 10 minutes and later Vegas starts to freeze. The next few freezes occur and then rest for 10 minutes.

The guys on the team have to test this mistake at least all day. It cannot be specified further.

Sorry.

Just to clarify. This is a video recorded from OBS. No effects added whatsoever.

Thanks, I wish I had known this was such a common issue.

pierre-k

Thanks again. I have tried all the obvious and known fixes. My repro is with a basic video and no effects and I normally work with only head and tail thumbnails. Thanks for all your effort. Much appreciated.

Alex-Pitel

Correct it seems nothing as changed, as I was able to repro within minutes of installing V18 trial. And also the fact the official support are obviously just fobbing me off.

Marco

Thanks for trying.

Unfortunately the application does not "crash." I have sent a full report to support but there can be no crash log when it does not crash. It freezes / becomes unresponsive for between 1 - 5 minutes.

I have sent details to official support. (See above). They suggested I change my graphics card. So I bought a new one. Same issue.

Just fyi: Ripple ON. Split lots. PLAY. Delete sections when cursor is over the section you delete. Sometimes it will take 5 - 10 minutes before the issue appears. Sometimes 10 - 20 seconds. It helps to repro if you zoom in quite a lot too.

I do agree the type of media may well be the issue. This really hit me after watching your video. There is a big obvious difference in performance. When I do splits and delete, Vegas performance seems to struggle more and more until the major issue happens. On your video it looks smooth. I have, as mentioned, a pretty powerful machine here. I have no issues with normal editing, rendering or playback when using effects and external monitor etc.

I will test with different media here.

Meanwhile, here is  a link to my exact media file used to show the issue (it is 146Mb). This is a very rough narration walkthrough so please do not scrutinize it. There are lots of mistakes, hence my need to edit a lot. :-) Would be grateful if you can try with this and perhaps also attach a link to a video that does not show this behaviour, (like the one in your demo).:

Thanks again everyone.

Do the minutes it is unresponsive for perfectly match the remaining video on the timeline?

So if after delete you knew there was 1min of timeline video to right of play head would the unresponsiveness be 1 min, and it can be assumed and known by looking at gpu decode that vegas continues to play the timeline only for you it's frozen, but internally it still plays.

Hi lenard-p,

I am not 100% sure what you mean. But let us assume the video is 10 minutes long.

When the issue happens, the whole screen freezes as you have hopefully seen in my demo.

Audio does continue in the background. (This is also mentioned). There is no activity on the GPU.

So if the freeze happens when the play head cursor is at 1 minute and lasts for 1min:30sec. When control returns the cursor will be at 2min:30sec.

So yes, playback is continuing but not relevant to length of video.

@hambonio, does the problem persist if you disable thumbnails in preferences>video?

@pierre-k, does the problem persist if you disable thumbnails in preferences>video? My guess is VEGAS gets overwhelmed trying to generate new thumbs on the fly while also processing video playback... though I'm no programmer.

We have tested this, please read above. Thanks for the idea though. Also please check my video demo. It happens within 10 seconds. There is no overwhelming going on from thumbs.

Also, would you want to use a video editor that does not show thumbnails of the video you are working on?

No, thumbs work just fine on my system... and I don't think the above would help your issue, I actually tagged the wrong person initially, I was responding to hambonio's post. It's possible that on slower hardware, thumbnail generation might tax the system a bit too much when splitting video, which is why I recommended that as a possible workaround. It may be their system doesn't meet minimum spec.

when I turned off the thumbnail display during testing, the failure increased by 100%. after several restarts vegas calmed down. and after a while it returned again. That mistake is coming in waves. A moment of calm. Hell for a while.

it is illogical. I know.

If you want to reproduce the mistake you have to make time. There's no other thing. Just half an hour. delete and delete on the fly. And for example, after 20 minutes, hell comes.

today I will publish a video about what is happening with Vegas in 30 minutes.

Also try using the video I attached in my post above as we are trying to find out if it is certain types of media that are affected.

Remember, zoom in, play, split, delete under play head.

Thanks. :-)

Here I can repro in 30 seconds. Using that media and the procedure I posted originally. I have already published a video on this. It makes no difference.

Does the crash report dialogue pop up when you do this? If so, enter your e-mail address into the field along with a description of what you did to make it crash. This will help the dev team isolate the problem, and they can reach out to you if they need to follow up for more info.
