some videos are choppy, some are not
Hello SV users! I hope someone can help me in this. I started a little project – a big music video combined by many videos. When I started it, everything was perfectly smooth. Then I saved the file so I can continue later. Then, some video were extrmely choppy and some are still smooth. Why? I also hope someone can tell me how to fix this problem. Thanks!

Hi,
Where do you see it choppy? On the preview, or in the rendered file?

In the preview. I didn’t try to render it, because I will need those vids smooth in preview as well. You know, there is a smooth scene, after it is for example 1 second choppy scene, so she doesn’t even jump in the preview and I need to see it…

Just select the part of the timeline that shows bad prview and go to the menu: TOOLS-SELECTIVELY PRERENDER VIDEO (make sure that RENSER LOOP REGION ONLY is selected!)

I’m not allowed to select RENDER LOOP REGION ONLY…

Why are you not allowed to select RENDER LOOP REGION ONLY? Could it be that you didn’t make a selection yet on the timeline?
Another way to improve your poor preview is to select this region on the timeline and select on the menu bar TOOLS-BUILD DYNAMIC RAM PREVIEW.

That was it, I actually just clicked it first, my bad.
Anyway, after the prerendering was done, the preview of the vid was smooth again. A tried to build dynamic RAM preview on different choppy vid and it did smooth it a bit, but not totally. But don’t tell me that I’ll have to do this everytime I save the project and then open it again? -
A RAM preview is temporaly, until you empty your RAM memory. However, it is supposed to be faster then a PRERENDER. But the PRERENDER is saved on your harddisk and is still there whene you open Vegas againn. The Prerendered file remains valid until you change something on this region….
A real permanent issue would be the option RENDER TO A NEW TRACK (Ctrl M).Theo

My advice is DON’T WORRY ABOUT IT. Let it play choppy! If you need to see it smooth, RAM render it and look at it. Once you’re done, render the whole thing out and it will ALL be smooth then.
