Preview Stutter and Crash when starting

Mick-Black wrote on 11/27/2023, 2:37 PM

Hello all, i'm new, but learning. Hope i can find some help after days of Googling hasn't fixed my issue.

I'm putting together a family video of our recent holiday. Recorded on a GoPro10 4k. Using Vegas Pro 21. When i preview my work in progress it stutters really bad and has become pointless. I've dropped right down to Draft/half and still the same results.

Project settings are 3840x2160 60fps as those are what i recorded in so tried to keep it same. Files being imported are MP4 (data rate 98964kbps 3840x2160).

PC Specs

CPU AMD R7 5800x

GPU 3080

32GB Corsair Dominator RAM

All drivers up to date.

*Edit Full details in comments below

Project seems to buffer alot next to the frame rate under the preview screen (dots......). Quite oftern the project crashes when i open it, it loads to 100%, but when loading media it freezes, black square over half the app and states not reponding, then asks if i want to close or wait for program, i've left it 2hrs and was still frozen

Any and all help welcomed, futher info on request as unsure what to pass over and so much to list.

Many thanks Mick

@Mick-Black
If your delivery destination is DVD why do you use such a high and heavy projectformat?
For DVD 720x480 is enough

@j-v when i convert and burn to DVD (Wondershare) it will reduce quality. I wanted to keep it as native as possible for render. I could look to drop to 2k and see if that helps. Assume you are suggesting the resolution could be the problem with stuttering? Monitoring CPU/RAM/GPU nothing is struggling or maxing out. I set max RAM usage to 30%, but never really reaches that. Thanks again

Of course is a switch from 4K >>DVD a quality loss.
But sorry I have no experience in keeping the high quality on a DVD, so sorry I cannot help you further.
BTW.: about max RAM usage, that is only being used when you use "Build Dynamic RAM Preview" (Shift-B) for previewing a selected small part of the project. Your selected amount cannot be used for other tasks (as previewing). If you don't use that option you have to set the Dyn RAM Preview Max to default or 0

Agreed, but i used Vegas many years ago using an older action cam. Rendered in 1080 then converted to DVD, it looked like a GIF lol. Wanted to keep the quality as high as poss whilst in the render phase so the drop at final draft isn't too low.

Try the link Vkmast shared. It should still look clear as a DVD.

For better preview performance with HEVC try right clicking on media and "create video proxy".

Set your project frame rate to 29.97 and you can use the GoPro footage for regular or 2x slow motion. Render to 29.97fps.
