Sony Vegas 9 pro HUGE files (wmv 720p)
So I’m having trouble with rendering a movie. It’s a little under 4mins, recorded with Fraps at 60fps. Here are the settings I’m using to render it; https://img227.imageshack.us/f/rendersettings.jpg/
I rendered it over night and it was like 2.3gb, I’ve been having huge files forever and it hasn’t bothered me till now. Some clips i have made are 10-15 seconds and are around 100mb+. It also takes a REDICULOUS time to render, somewhere close to 5hours+ (For this particular 4min video)
I don’t know if this matters but I’m running Win7 64bit with 4gigs of ram, and nothing else is running in the background when I’m rendering.
Thanks in advance.

What are you doing to the FRAPS files? With a lot of FX especially CPU hogs it could take many hours to render that 4 min file.
.WMV is a pretty slow render in the first place. Do you NEED .wmv? For posting to Youtube or the like the Sony AVC will be faster. For the project properties you want to match your input file spec. If it is 60 FPS the 29.97 Project property will eat up some CPU as the computer tries to convert this on the fly. Better yet just capture the FRAPS at 29.97
As for your output file size it does not match what you should be getting with the rendering specs you provided. Are you actually outputting Uncompressed?

Rendering time is the sum of the different times involved. If you’re on a fast computer, rendering to something like Cineform or MPEG-2 is probably at or near realtime (eg, 4min render takes 4min), probably less if you’re output format is SD.
But what else is in there. Right now, I’m rendering a special effect on a 5min segment of video…. a BCC7 temporal blur effect. Each frame that’s rendered is based on effects applied across ten HD frames… that’s never going to happen fast. In fact, for that five minutes, its run over an hour and 45min, and expects to go another hour and a half. You can take about 5min out of that for rendering (I’m rendering to 50Mb/s MXF MPEG-2… I’d normally use Cineform, but it’s broken in Vegas 10… yeah, even with the latest version of NeoScene). The rest is due to the effect plug-in. And this is on a 6-core AMD at 3.2GHz… not the slowest PC on the planet.
As for size… what’s your bitrate? That’s what determines size, and pretty much, quality as well. If you want smaller files, change the details on your rendering. WMV9/VC-1 can be nearly as small as H.264 at the same quality. If I wanted high quality WMV9 for upload to YouTube in 1080p HD, I’d probably choose something around 15-20Mb/s, half of that for 720p, as a minimum (knowing full well YouTube will transcode it). A 4min video at 20Mb/s will take up about 600MB. If you rendered for easy internet play, say 1.5Mb/s (and lower resolution, or it’ll look BAD), that’s 45MB for the 4min video.
