Split + Delete (While Playing) Causing Huge Hangs

OK I have moved the video to WeTransfer. There are 3 files. Download is valid for 7 days.

  1. Instructions to repro text file
  2. Demo video that shows and explains what happens
  3. A video titled "use this" that I use to get the repro


I would greatly appreciate folks quickly skim through the thread to see what we have tried already and try the repro with the linked files.

Thanks. :-)

Thank you, this will be helpful. I'll make sure the team sees it.

COMPLETE PRESENTATION OF THE PROBLEM WITH AUTO RIPPLE IN 26 MINUTES AND BONUS VIDEO WITH EVENTS FROM THE MEDIA GENERATOR




FACTS:
- An error message is NEVER displayed
- video formats do not matter. The error can also be reproduced with events from the Vegas Media generator
- the length of freezing is almost always the same - 1:50
- The CPU GPU HDD is idle during the error. No fluctuations or extremes.
- the repetition of the error is unpredictable.
- Thumbnails can be visible or hidden. It does not matter.
- The problem occurs even when the GPU is turned off.
- I had about 13 freezes in 26 minutes.
- If you close the video preview window, the error does not occur.


And if someone tells me now to send a bug report, then ..... 😹

PAP, thanks for sharing this media. I now tried several times with your source clip and according to your description to repro, but I can't. Sorry, but it seems I can't help in this particular case.

What makes me curious, though, is that I only use a rather low end notebook since most of the stuff I edit is either broadcast or educational video which both doesn't take more than a few of standarized HD media types for input and output. My system is even below the officially recommended system specs (it's an Intel i7 6500U with Intel HD Graphics 520). I would have expected this issue would be even easier to repro if you use such a low end system. But it does not seem to be related to CPU und GPU power. It's a tough one.

Here also not possible to repro on laptop from signature, not with big 4K DJI files and not with your downloaded file.
I hope I tried as you intended, look ( in the view of the taskmanager is also visible the extra use for making that screenvideo with Screenpresso)

You mean Camtasia? There are things in my Task Manager of course for the purposes of recording this demo. I don't usually record myself editing a video. :-) Thanks for trying anyway.

nb. Windows here so only really 2 options, OBS or Camstasia. There are smaller applications for making animated GIFs but we cannot use/upload GIFs here. Anyway this off topic. What I have in TM is there for the purpose of showing everyone here and is not part of the problem I assure you.

Next thing wee need t look at is the GPU itself I guess.

Hi Marco,

That is interesting. A low spec machine does not have the issue. I mentioned above about GPU. I am on nVidia here as mentioned. I wonder if the other guys can mention which GPU they use and if they have the issue?

Thanks again. :-)

No when I say Screenpresso I also mean that easy little prog , a tool I use already a very long time as Founder and Moderator of the Dutch Vegas forum for making Pictures and Instruction videos. On this website you can find it, a free version and a (little) payed version: https://www.screenpresso.com/

Hi j-v Ok got you. We use Screen to GIF generally and Camtasia also Snagit, all very useful for beta testing. :-)

Phil_P wrote on 8/5/2020, 1:55 PM

Slightly breaking news: The video file I sent is indeed not required to repro this. I am able to repro just using Vegas media generator files. Exactly as Pierre mentioned. It took me 30 seconds to repro.

What makes the issue even stranger.

Could you test something really nuts? How about if you use Empty Media only (which you'd create via a video track right-click option). Same issue then?

pierre-k wrote on 8/5/2020, 2:08 PM

I've been devoting all day to this problem. without success. I think the problem is with the CPU load.

I have a 4 core intel Xeon 3.4Ghz. And you?

Wow! I was able to repro instantly with empty media as you suggested. I don't know what conclusion we draw form this though... :-)

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

I have not thoroughly tried this in VP18 yet, currently working on setting up my 2nd PC from fresh Windows install. This will be tested extensively this weekend for sure as I have other issues from my other install I am still looking to resolve. It was pure frustration in VP17, having to train myself to pause the video every time I needed to split a clip just to avoid a crash. And yet, I still failed at that move. I would love to just split in real time. This PC has an RX480 in it, the other one a Radeon VII. I never had an issue in VP14.

i7 (12 core), 64GB RAM, all SSDs. Also mentioned above is that Marco is not getting the issue on a "low end laptop"... This is not a CPU power issue. I have stated from the start, it happens with one video track, no effects. And just now was able to repro with empty blank media created within Vegas.

I have no problem running multiple tracks with t9ons of heavy effects. It is just this ripple / split / delete that causes the hang. :-)

Full kit list is in my signature btw.

Yes I get you. I have been struggling to find a workaround here.

Disabling thumbs helps a bit (for a a short while) but I need them. And there is no Key Command to turn them on and off.
Using F to post ripple historically is a possibility but leaves a lot of guess work.

btw. I was able to repro with empty media in both 17 and 18 (18 is Trial). :-/

btw guys I have directed support to this thread with my support ticket.

"I was able to repro instantly with empty media as you suggested. I don't know what conclusion we draw form this though... :-)"

This together with Pierre's info that it also happens without having the preview window opened tells me it has zero to do with video processing. I think this is valuable information for tracking the issue because this excludes tons of cases.

Marco. wrote on 8/5/2020, 3:31 PM

@pierre-k @Phil_P

Maybe I just found the cause.

I never ever used the Windows text scaling, mine is always set to 100 %. After we now found the issue isn't based on video processing my assumption was it either has to do with meta data management or it may be just a GUI conflict.
And while thinking about what may cause a GUI conflict I tried to set my Windows scaling to 150 %. Retried the test and after 20 seconds deleting events I had a repro (with using Empty Events). The first one ever.

So could you check how you have set your Windows text scaling? If it is not set to 100 %, try setting it to 100 %.

Maybe it's a translation error, but I'm saying something else .....

If you close the video preview window, the error does not occur.
In other words - it works perfectly if you close the preview window.

sorry for the misunderstanding.

Assuming setting monitor scaling to 100% will fix it, on a 4K monitor - the text is now microscopic and almost impossible to read. Hopefully this is something that can be fixed within VP.

Having found the cause (if so) does not yet mean having found the solution. But it would be an important step.

Do you mean this?




I have 100% on all monitors and an error occurs.

Marco. wrote on 8/5/2020, 4:09 PM

Yes, that's what I meant. Strange again and a pity. I did many tests in the last 30 minutes. Each time I set the Windows text scaling to 150 % I can repro the issue within a short time. And each time I set it back to 100 % I cannot repro the issue no more.

Maybe there are totally different causes.

Still curious what PAP means.
