Anyone have any ideas or setting suggestions that may help preview performance?

Thanks!

I'm having similar issues. It's a bit odd that 8 Pro was fine, but 9 Pro is stuttering a bit. Megapixel images (panning files that are only approx 2400x1800).

Bug?

I get the same playback performance problems with 'Draft - Auto' or 'Best - Auto'.

No difference at all. I sure hope this is a bug. 9 Pro is unusable for me.

Yes,
Even with one video track and audio track the choppiness is the same in Best and Draft. Even when the size is half in draft.

Is there a setting that can minimize the latency and choppiness in draft mode?

Thanks!

OK I've tried the render to memory it works but that just takes to long...
BUT...
I've found a workaround (maybe) :

In File Properties I've reduced my frame rate to 15fps. This has significantly improved the preview play back to where it is very usable.

Now my question to the Experts: If I import and edit my 30fps video at 20, 15 10fps, then change the frame rate back to 30fps when I do the final render, will all my clips that I've imported maintain their original 30 fps upon final render or will Vegas trunk my videos down to 15fps because I was editing at 15fps?

In other words if my original clip was 30fps, I edit at 15fps and render back at 30fps will the video play back only 15frames (play each frame twice) at 30fps?

Is Vegas smart enough to re-insert the omitted frames when changing the frame rate in Properties back to 30fps? I suspect that it should maintain my 30fps upon final render because it's "non destructive" editing but just need some confirmation if this is a valid work around.

Thanks in advance for any much needed advice on this!

I'm having the same choppy playback issues. I've also had some odd display issues too. After I perform a selective render my secondary display is distorted within Vegas. If I exit the software and reload it behaves fine. I like many of the new features, but right now I don't think I can edit a major project on this. The latency is way too severe.

I have the same issue. Made the upgrade from VMS Plat Pro 9, where my Canons HG10 .mts files worked pretty good, to Pro 9. Believing that things can only get better. Not so.

The preview is extremely choppy and laggy and there is no difference between using draft or best. I'll try Byrons workaround and see if that works.

Byron,
If you make a change in Project Properties, that doesn't affect the original files at all. So to answer your question, if you set the Project Properties to 15 fps and then change to 30 fps, Vegas will render them at 30 fps. But if you're not sure about something like this, it's a good idea to just render a minute or two from the timeline to see what you get.

I have no issues playing back avchd (from the sr11) at full framerate (except transitions...effects...etc) in preview mode. Are you sure your settings are correct?

Using the same clip in both Pro 8 and Pro 9 - Pro8 is smooth as butter on full screen (1980x1050) at Best quality, while Pro 9 choppy in playback in any mode. This is hardly a step forwards.

Let me amend my last statement.
Pro 9 runs the same clip smoothly in preview - as long as there are no other tracks other than the video and it's associated sound track on the timeline.

As soon as any other track (music, Fx, etc.) is added to the timeline the choppy playback starts, even if the video is soloed.

So it is not the video track causing the choppiness in Pro 9, because Pro 8 runs smoothly WITH all the extra tracks enabled.

My preview is Choppy also. V9 64 bit seems the worse. Preview runs smooth in V8 in all cases I have tested. I've tried to narrow this down but can't find anything to cause it. All I'm doing is a simple "pan" on a 1310 x 960 PNG file. Nothing else. No other video. No audio. You can tell something is wrong. Even the "crop" in pan-crop window is jerky!

Can't get a smooth preview on this simple action in V9 64 bit. V9 32bit runs it smooth until you start adding other elements. At some point, it goes bad too.

I see I am not alone on this problem. I'm running 64 bit Vista. 4 gigs ram on a Q6600. Hoping for a solution soon!

Agreed. A single video track will run smoothly. Once FX are added or additional tracks are added the preview is very choppy. Either way, though, selective rendering corrupts my secondary monitor output until I restart the program.

"Agreed. A single video track will run smoothly. Once FX are added or additional tracks are added the preview is very choppy."

Then use SHIFT-B.
That's what it was created for.

I'm not an expert but it feels to me like memory problems in V9 because I've noticed that closing V9 (64 bit especially) and restarting it seems to solve some problems where things do not display or where simple features like pan-crop seem to totally freeze up.

My first thought is that my system has the problem. But after running V9 since it came out, I'm starting to think otherwise. I'd like to be proven wrong.

Have you tried turning off the option "Adjust Size and Quality for Optimal Playback"? Right click the preview window and you will see it.

Hi guys,

I'm not one to complain but I am experiencing the same problem with V9 64. V9 32 I do not have this issue- so a bit of an anomaly. I did a pan & scan of some pictures I took while in Africa with 1 audio track. Playback was horrendous in 64. I also attempted to use some panoramics I stitched together in Photoshop CS3. They showed correctly on the timeline and while playing through the image's keyframes (although it did stutter badly). When I clicked on the pan & crop icon they showed almost as negatives of the pictures. When I rendered it out it showed the same way on the finished product. However, playback displayed the pictures with the correct colors.

I took the same veg file and opened it in V9 32 and all was well. No issues and it even handled the extremely large panoramics without issue.

I may make a new thread for this later complete with one of the panoramics and screenshots. I just got to get a few things done.

Shit+B is not the solution. I don't have to do that with Vegas Pro 8 so why should I have to do that with Pro 9?
The choppiness is something peculiar to the Pro 9.0 version and needs to be fixed.

I agree with hoteldelta. I'd like to be wrong on this and find a way to adjust my Quad system or adjust V9 to run as smoothly as V8 -- but I'm not hearing anything like a simple fix. Perhaps V9 runs smoothly with certain media on certain systems but it seems like V8 ran smoothly with a wider variety of media and systems (including mine!). -- Anyway you cut it -- something is up with V9. Too many of us having problems on the exact same files and media that run smoothly in V8. Of course we were all running 8.0C -- and it took some time to get to "C". I'll be patient and keep trying to find out what works, what doesn't and why.

Sorry guys I haven't been keeping up with this thread because I had 5 projects to do for a family member this week.

Anyway, I spoke to soon about the 15fps work around. Initially I thought it was all good but as I continued to work on the project (2 video 2 audio tracks) the latency and choppiness increased and I reverted back to Platinum 9.

I submitted a question to the tech support and this is the response:

/Quote
First of all, please be sure that your project properties match your media properties. Next, please try increasing the Preview quality. Does this make a difference?

Also, please right-click within the Preview window and uncheck the option to Adjust size and quality for optimal playback. Does this help at all?

Finally, please update this incident with the following information:

--What types of file(s) are being used in your project (please be as specific as possible).
--What the properties of your project are.
/End Quote

Maybe this can help others who are having this issue. Though these suggestions did improve the playback initially, as I continued editing the project the choppiness increases and audio goes way out of synch. This was with my smallest 5 minute project of 2 video 1 audio track. The problem goes away after restarting Vegas 9 but comes back as I continue to edit and preview the project in Good, Best, Preview and Draft. (Why play back would be smoother in Good or Best rather than Draft is beyond me...)

I have a respondedse to the tech support and am awaiting an answer.

I made a quick video of what I'm talking about here:

First clip: Vegas 9 very choppy preview Good, Half.
2nd clip: Platinum 9 Very smooth w/ transistions and effects Draft, Full.

Thanks for all your responses. I'll keep you posted on the results w/ tech support. Until then I'm continuing to use Platinum 9.

FYI.. The other 4 projects were done and completed in Platinum 9 no problems.

Then use SHIFT-B.
That's what it was created for.

I do, which then corrupts the Windows Secondary Display until I restart the application. I've tried this on two different computers I own with slightly different NVIDIA cards, with the same result.

Have you tried turning off the option "Adjust Size and Quality for Optimal Playback"? Right click the preview window and you will see it.

Thanks for the suggestion. I tried it and it had no impact on either of the display issues.
