I am experiencing the same instability with constant crashes. I"M not sure how to account for it. Unlike you though Roger I've really enjoyed VP19 build 532 to such an extent I saw no need to upgrade to 550. It was exceptional compared to previous iterations. But now I"m in the same camp as you. It seemingly occurred after a double windows update. I don't believe I"ve installed any VST's or VFX plugins anytime recently .

So not sure what to tell you, build 532 and I assume 550 can be amazingly stable, but at this time, i'm unsure if I can regain that stability

- Which drivers for the Intell and Nvidia GPu's are installed?
_ Which sources are used? Give the MediaInfo.

All the GPU's drivers are updated.

I can't give the media info trough the "Give the MediaInfo" link because this is for media (video) and my problem is for the whole software.

That make none sense to have those crashes and lags in a poroject that just have a slow motion applied.

I think you don't have the solution to fix that.

My computer is pretty new, I play video games with no problems and everything work perfect less Sony Vegas

Sorry...I'm really disapointed...I'm not asking for nothing special. Just be able to do simple video edits

I can't give the media info trough the "Give the MediaInfo" link because this is for media (video) and my problem is for the whole software.

Yes, that link is to get the information on the type(s) of video you have on the timeline. That can make a HUGE difference and that information is needed if you want help.

Also, Vegas Pro 19 is NOT Sony... It's Magix since version 14.

Yes yes ok, I'm using Vegas Pro 19.0. Not Sony, sorry...

The problem is that the issues are not only ina certain media, the issues are in the WHOLE software. Is not normal to work with an 1050Ti GPU, 64 gb ram and a i5 processor with 6 cores and have problems editing so simple edit.

@Roger-Trigo, so with NO media on the timeline, VEGAS is laggy?

Seriously, what is the media? When I use my 4K footage from my Osmo Pocket camera, I can get 30 frames per second on playback.

When I use the HD GoPro footage, it often will not reach 30 frames per second.

When I lower the playback rate and I use Optical, it will really struggle to keep up.

So, yes, more information is needed. Unless VEGAS is struggling to do anything with NOTHING on the timeline.

Here is the media that makes it lag.

anyway,I could send you almost all the medias I worked because they also lag, only with a fade in transition , it lags. I can imagine what will happen if I add some effects or I just mix it with another video. It's not normal

@Roger-Trigo,
Thanks for the MediaInfo.
It tells me that you work with pretty heavy sources.
I asked you another question about needed drivers.
You working with Vegas 19, you can read that in Help/Check for Drivers Updates. Give us a screenshot of the picture after clicking that option.

Sorry, I don't understand wich screenshot you need, and I can't find the Help/Check for drivers link.

Thanks for your help

Look:

Thanks, I see you are using the latest drivers, those can't be the problem.
For the Nvidia and the use at video editting it is better to use the s.c. Studio driver , for you with nr 512,59
At editting set the preview at preview auto or use proxyfiles for no lag and be patient.

Have you experimented with other settings in x264?

Thanks, Yes, I have this configs as it shown on the video

sorry, don't know how to change that setting

Thanks, Yes, I have this configs as it shown on the video

I''m almost out of hints.
For maybe the latest I need pictures from you showing Options/Preferences/ Video and Options/Preferences/File I/O

Have you experimented with other settings in x264?

sorry, don't know how to change that setting

How did you create this file? It was encoded by x264.

Checked your mediainfo.

"Overall bit rate mode                    : Variable"

I have had similar issues when processing variable bit rate videoclips from my cameras or Vegas video hub. Converting them to constant frame rate videos (for example using hand brake). Trying creating proxy via Vegas UI could help too.

@Erkki

Don't confuse ""Overall bit rate mode                    : Variable"", then offer a solution to convert the media to constant frame rate.

@Roger-Trigo

What camera, recording device and/or software produced your media?

Are you so concerned about file size or compression efficiency that you don't want to drop an I frame ever (keyint=infinite)?

Could you share a sample of your media on a cloud drive and post the link here for others to test?
