MPEG TS is slow in Vegas pro 8

[John Rofrano]

What camcorder did you get? How powerful is your PC? (CPU, Memory, Number and size of hard drives) Is your footage on your C: drive with your swap file? All of these things affect performance.

I am using a Sony HDR-UX3

My computer has 2.0Ghz, 1.5GB of ram and i’m using my hard drive

What is the swap file?

Thanks

I have a Sony HDR-UX3

I have 1 250GB hard drive, 1.5GB ram, 2.0Ghz AMD Athlon processor.

Yes the footage is on C: and what is a swap file?

Thanks

The Sony HDR-UX3 is an AVCHD camcorder which requires a Dual or Quad Core computer. Even the Sony requirements for Vegas say this. A single core 2.0GHz computer is inadequate to handle this cameras’ output. You should seriously consider upgrading to a QuadCore computer, or shooting in SD MPEG2 mode.

As for the swap file… this is file that windows uses when it runs out of real memory. If at all possible, you should not keep your projects and media on the C: drive because as Vegas needs more memory to read your HD file, Windows swaps memory out to the same hard drive that Vegas is trying to read the file from. This results in the hard drive trashing between reading your HD file and writing to the swap file. It can only do one or the other but not both at the same time. Having your media on a second hard drive allows Windows to do both at the same time and greatly improves editing performance.

The good news is that your camera also shoots SD DVD quality MPEG2. If you want to edit on your current computer you might consider forgetting about HD for now and recording in SD mode. Otherwise you really need a new computer to handle HD.

Ok thanks

He could also shoot in HD, but capture in SD, until such time as he can upgrade the machine to handle HD editing. I did that for almost a year, when media and machines to handle HD were outside my budget, and at a time when there were very few demands at all for HD output. That is if that camera will allow it. Even now I pretty much expect my next big project to be downrendered from 1080-60i HDV to DVD as has been everything I’ve done that’s not streaming 720p.

My Canon XLH1 did allow for either HD or SD capture from HDV source tapes, though it took some reading of the manuals to make the transition to HD capture once I did have a QuadCore machine and enough RAM to make rendering something other than 7+ hours of constant prayer.
