Is 9.0a slow slow slow?

I've switched from 6 to 9a. Is it me or is 9a really slow?

I used to be able to play at 29fps all the time. Now, even one track with no fx runs at 15fps or even as low as 7 to 8.

It is very difficult to sync audio to the video as the slow playback gives the false impression that the audio is not sync'd.

Is it me? (Pentium 4, 2.8 ghz, 2g ram) Or 9a?

There are significant differences between 6 and 9a, and also differences between 9.0 and 9.0a.

Vegas Pro 9.0b is due by next Thursday. One more week.

Hopefully it will sort out your situation

But there is always the possibility of system issues ...

I think some more details would be in order e.g. what is on the timeline. Also there's more features in V9 than V6 that could be using more CPU and/or RAM on an older machine. It'd be worth checking the impact of things like Auto Adjust Preview Quality (or whatever it's called).

I'm running 9a on a P4HT 2Gig system also. I have to do most of my editing in preview / half resolution most of the time. Good or Best is really choppy but it's just the limitations of my processor. If I need to see exactly how the transitions and effects look in higher resolution I render that part to RAM to view it. This method is a little tedious but works until I get a faster machine.

9a, at least for me, has made playback so much better but I've noticed as I continue to edit playback gets more and more slow and choppy and I have to change the resolution on the Preview window and it works OK for a few minutes then starts to get choppy again until I change resolutions then it's OK for a while etc. It's kind of a pain but I'm at least able to work w/ Vegas9 now.

This thing of changing resolutions, getting good playback for a bit, then having to change it again...

This probably has to do with your preview RAM settings. Vegas caches frames into this RAM pool as you work (Not just when you do a RAM preview) and this will fill up the RAM Preview memory. This can become a problem if your RAM setting is set very high because it will eventually force your computer to start using the page file. When this happens *everything* slows down.

Some changes to the preview resolution setting will make Vegas throw out the old cached frames and start saving new ones, and then you start the cycle over again.

Look at your preview RAM setting and if its high, reduce it.
