Render time at DVinfo.net

Hi,
Probably an old question.. but its late at night here and I have a deadline (!)

I have a 40 minute file, no effects, just the addition of two title frames at the start for ID.

To render this to MPEG2 at 8Mbps Vegas states 1hr 58 min required.
(It rendered the entire thing to an .avi file in six mins..)

Trash emptied, defragged, files on separate hard drive to Vegas and OS (XP)
chip is a 3.2Ghz, 2Gb RAM and loads of hard drive. Two screens in use.

Any ideas?

Ben

My guess is that the estimate is probably fairly close, especially with a 3.2Ghz machine.
Vegas will always render to AVI much faster than any other format as that's what it's native format is.
Anytime you have to transcode to a different format, it'll take time to do the necessary math.
I had a 10 min. project take 3 hr. (lots of tracks and FX) on a P4 3.4 GHz machine.
That same project took 27 min. on a quad core.

Mike's correct, of course. For any significant speed increase you will need a newer processor. You could double your speed with a new $500 low-end desktop.

u won't wanna hear this but i'm thinking to myself "that sounds pretty good".
i use a 1.8Ghz dualcore (about to be replaced) at work and it averages:

7 minutes render = 1 minute finished

Drives: (3) OS / data / renders
Output: m2v, CBR (6.8av / 7.5max), 2-pass, 29.97, best (some still images)
Filters: cc > black restore > unsharp mask

caveat: almost all my source is square-pixel of varying image-sizes... rescaling on output adds to the render time; especially if the source was significantly larger.

side-note: i find the time estimate for mpeg rendering stays fairly close-to-true once it passes about 3%.

You are pretty right there!

I was using a laptop with an 800Mhz chip, 256K of RAM and a 10Gb disc up until three years ago, and I was pretty amazed at its performance which outshone the latest and greatest at work.

Seven mins render for one minute final vision was about what I was getting... let alone the number of freezes. An overnight render was literally that; overnight, with it usually finishing in the early hours.

Funny how we forget such things.....
