video slowing down in timeline

studioLord wrote on 10/24/2013, 3:18 PM
I have a quad computer w 32 G of RAM (just built)

When I add a text over the video clip in MS Platinum the video slows down. Otherwise the video plays fine. I just bought a JVC GC PX100 HD cam to do HD and I have version 12.0 of MS Platinum

I just added 16 G of Ram today bringing it up to capacity for this computer.

Is there something I can do about this? or do I have to wait and see what the results are after the render?

I would also like to know how to turn on the feature that shows a colored line appearing when you match up clips or transitions in the timeline. They used to appear when I lined things up but for some reason they are not showing now.

You can try a RAM pre-render. Select a small section of the timeline surrounding that part you want to see and press Shift-B. Vegas renders that section to a RAM buffer and will then play it back at full frame rate.

wow! That was fast... (reply)... I was editing the post as you were writing your answer... I'll try it and respond... thanks...

I highlighted a section and pressed "Shift B" ... it just sent the cursor back to the beginning of the hightlight...

You may not have a pre-render buffer set up. Under Options / Preferences / Video, look for "dynamic ram preview max". Generally you can set this to be around half of your available RAM up to about 1GB. This is the temporary storage space that Vegas will use for the prerendering feature.

Okay...When I hit "shift B" it made the highlighted section smaller but it did play back... only without audio...

Try increasing the Dynamic RAM further. VMS will only render to a max of the RAM you specified. In a high def project, it gets eaten up pretty quickly.

If after increasing the Dynamic RAM buffer you still have problems, try reducing the preview quality gradually until you get a smooth preview playback. I always use 'Preview Half' which, on my system gives me several seconds of smooth playback. The length of RAM preview you can initiate depends upon a number of things, mainly the complexity of any FXs added to the events.

After all rendering some part to file and viewing that file is not that bad idea. For cases like lossless source I use preview in Vegas only for effects set up, not counting on real-time playback.
After preparation of some significant part, I render it and review the result in player. Some mistakes in project or render settings just can't be catched effectively without it.

Render your preview file or a segment to MPEG-2 720p, that is fast and looks good.
