Render crawl
I’ve noticed that anytime I render a video in the length of 15 minutes or up, Vegas blasts through the first 1900 frames or so and then slows to an absolute crawl.
Anyone have an idea why this is? Those first few seconds of rendering make me thing things will be over quick, and then I realize I’m in for a long nap before I can deliver the file.

Elvis,
Just for grins, go into Options|Preferences|Video and reduce the “Dynamic RAM preview max (MB)” to 0 and see if that changes how fast it renders after the first few hundred frames. It always works for me.

Elvis, you didn’t give your computer specs, say what kind of material is on your timeline or what format you’re rendering to so any answers can only be very generic.
If your computer is underpowered, renders will take longer.
HD files and/or extremely large images will take longer to render.
Adding any kind of FX to your events will increase render times.
Certain formats will take longer to render. -
Jeff, setting that value to ‘0’ is never recommended.
Instead, set it to a low number such as 16 or 32. -
Mike,
When I use RAM preview I set it to 8192, I only turn it off when rendering.

That’s the thing- it happens on everything from my old Athlon laptop to my i7 920 with 12gbs of ram. It doesn’t seem to be a hardware specific issue, but something in the software that’s causing a chug.
I’ll give a try to the 0 memory thing. I often have my desktop set to that, as that’s what Raylight recommends but I’d just changed it to 8192 for a non-Raylight project.

Elvis,
Yes, do try the 0 memory thing and please, please let me know your results.
I set mine at 8GB because I have 24GB (33% of total) Your setting of 8GB of 12GB (75%) may be a bit much.
Just my opinion.Jeff
