Frequent hangs on a fresh Windows 10 install (Movie Studio 15 Platinum

Paul-Ortiz wrote on 1/20/2019, 7:37 PM

Hey everyone. Just reposting this as I'd originally put it in the wrong forum. So, new Windows 10 install on an i7 4700 MQ, 12GB RAM and a GeForce GT740m. Latest version of Movie Studio 15. I'm doing screen captures from OBS, using the h264 encoder in an MP4 with two audio streams; one for voiceover, and one for audio captured from another source.

The problem is that Vegas is using absurd amounts of CPU while previewing, even in draft half or quarter; up to 100%. The playback also alternates wildly between smooth and less than 1fps, and the program frequently hangs while doing things like starting playback, resizing or moving events, etc. It's not a full crash...I just have to walk away and do something for like a minute and then it comes back.

Something's definitely amiss here. I did think at first that it was due to me recording using the streaming codec from OBS, but I've since changed it to NVENC and there's no improvement. I've got GPU acceleration on, and I've tried switching the actual app between the nVidia and Intel HD graphics. Nothing seems to help. I'm not sure where the fault lies. It might be some video setting I'm unaware of (it's not my forte) or it might be something else. Any help at all would be amazing! Thank you.

Try these OBS settings instead and let us know if it makes a a difference:

At the least, they should give you better quality.

What are your projectproperties, if they are different from your sourcefiles your CPU has a lot more work to do to show the files in the other projecttype, mostly due to other framerate or other dimensions.
When your program is allowed to play the file as they are, the CPU has only to unpack the AVC codec and some other minor things.

Hi! Sorry for returning to this thread so late - I just wanted to say a HUGE thank you to Musicvid for sharing that article. It 100% fixed my problem. I'm able to edit quickly and smoothly without any hangs or crashes, and you've *totally* saved my bacon with this particular job. I know it's always good netiquette to inform others if a solution has worked, and yours has. So a huge thank you from me!

Just to add a tiny bit more detail to this; MusicVid your suggestion definitely improved things however I was still getting the hangs every now and then, with preview performance dipping from time to time. I narrowed it down to two things;

Resizing the video lane so no thumbnails are visible fixed all preview issues. I think the redrawing of the thumbs when jumping around the project was causing some issues for me.

Also, Vegas doesn’t like me deleting clips while the project is playing. Since I stopped doing this, no more hangs.
