Anyone else? Playback issues?

MUTTLEY wrote on 5/11/2009, 10:29 PM

So just seeing if I'm alone and unique over here. After a while of working the video starts playing back slower than the audio. It's a gradual thing but once it starts happening it gets pretty ugly and is becomes pretty much unworkable. I'm using the 32 bit at the mo as I need some plugins that arent yet 64, on Vista.

I just played back about a 10 min piece with no problems except some of media coming off my trusty little Z750 Casio camera has problems. I had the right codec to solve this problem in 8.0c but looks like it will be no go in 9.0 -- may have to convert the media to standard avi. No big deal. Not noticing any lose of sync or audio slow down. --- Weird that it would do that.

Hm, I'm having that issue and then also, on some parts it will refuse to show the vid. Really quirky stuff here. At points it'll show the clip in "Preview Auto" but if I change to something else it it will either show all red or all black, or show the video but without the effects even though the effects are toggled on.

V9 performance on AVCHD files is poor compare to V8. Video is very choppy no matter what the preview setting is. Expecially during a transistion or if an fx is applyed.

Not sure, these are mxf flies. HD 1080-24p

Kinda stuck now, almost impossible to edit and can't open the veg back up in 8.

Not my experience. Better playback than with V8c for me...

I'm finding that the audio is a little behind the picture. I don't know if it gets worse as you play the timeline or not. It was far enough behind that I can't work that way and so I am back on version 8 for now.

You can always go back to a previous version of Vegas by saving the project as a Vegas EDL and loading the EDL in the previous version of Vegas.
MUTTLEY wrote on 5/12/2009, 4:03 PM

Unless I'm mistaken EDL will only do cuts/fades and not all the effects and this particular project is pretty far along. My bad for not saving over the original version when I opened this one up in V9 but it grovels none the less.

Yes, I noticed the sync problem with pic and sound. I have to close out and open back up when the problem starts. I rendered a project last night and the rendered MP4 was out of sync as well. Will try again tonight.

Using the Demo,..got allot of the old "red screen" in the preview last night. I havent seen that in quiet a while. Editing tons of AVCHD + HDV.

Got a render crash too. I'm going to install Windows 7 64bit tonight and try out V9 64 demo.

I wonder if I'll crash. Wish me luck.

I created a video again tonight and it was out of sync again. I went in and turned off the optimal playback option and the video & sound renders in sync now. Although I need to do some more tests to know that it is perfect. Hard to tell with the video I am working on.

>>...video & sound renders in sync now...

Are you saying that video and audio rendered out of synch before? An actual *render*, not just a preview issue?
Harold Brown wrote on 5/12/2009, 8:09 PM
Yes, the render was just like the preview. It was out of sync. It seems to be related to the amount of demand you are placing on Vegas. I had overlays and music and titles and the preview was out of sync in that area but later in the video it was ok. When I rendered it out the sound was out of sync exactly as it was in the preview.

From a quick analysis (needs more testing) it appears that the optimal playback is impacting sound sync in both preview and render. At least for me it is.

The first clip had DeShake applied so I don't know if that had anything to do with it. Will test more tomorrow.

Playback or preview? My previews aren't as smooth as in V8c. I'm finding V9 a little on the herky jerky side (even in Preview mode). Even when I was pan/scanning large images in V8 (pre crash because of big files) I never had an actual problem with previews. Something needs a tweak.
MUTTLEY wrote on 5/12/2009, 11:09 PM

I haven't even got to the stage where I can render yet, grrrr ...

But now I have something else to worry about if I'm ever able to successfully make the changes I need to make! Thanks for that!

So is this like a memory leak or something?

Try going to options/preferences/audio device and check the "automatically detect and offset for hardware recording latency" tab and see if that helps.
MUTTLEY wrote on 5/12/2009, 11:20 PM

That "may" have done it, if so I'll kiss you but still to early to tell so keep the ChapStick in your pocket! You did make me look at my V8 settings and both that and "Enable Track Buffering" are enabled on that version. Are these even necessary with a decent computer?

Anyway, will plug along and report back. Crossing my fingers.

Still kinda there, no kiss for you.

Literally its like the video is not only out of sync but starts going in slo-motion.

I am getting V9 to freeze with cpu usage jumping to 100%. Restart V9 to cure.

m2t files on timeline captured from Sony HC3 using Vegas capture. No effects. Just bunch of files dragged from explorer.
Happened about 3 times yesterday.

Win XP pro SP2 on core 2 duo. Upgrading to SP3 at the mo.

This morning, working ok !!
Will try and do some editing later.

Trying like heck to push through this project but no easy task, if it isn't playing back out of sync or the video going in slo-mo it's the red and black frames where I can't see the video at all.

They have clearly done some work on playback, and it goes a lot deeper than just the auto quality adjust.

If you look in the INTERNAL preferences you'll see some additional playbackoptions that weren't there before:

Playback first slow count
Playback additional slow count
playback post average count
Playback percent switchback
Playback additional after switchback

I can't however for the life of me decide if this makes it better or worse. It certainly reacts differently than 8. With avchd playback sort of skips and jumps to life until full frame rate is reached. A bit irritating because I have to start palyback at an earlier point on the time line to allow for frame rate to be reached. But then when it reaches full frame rate it plays well until a transition or something at which point it does this tremendous skip/jump thing again. However once a particular part of the time line has been played then repeated playback over that area seems to be much more stable. In other words the buffering into memory seems to be more solid.

I still haven't made up my mind whether I like or dislike this new behavior.... better in one instance... worse in another. I did get quite used to using dynamic ram in V8 so I don't think it's a killer issue either way.
MUTTLEY wrote on 5/13/2009, 12:00 PM


I'd be ever grateful is someone could figure out if some of those new settings could be causing these issues and if not, what could. Though there seems to be some differences in symptoms this doesn't appear to be isolated to just me. It's just nary impossible to edit with the wonky playback and video going to red/black frames.

not that I have a lot of help to offer, but has anyone submitted this as a bug report to Sony yet?

MUTTLEY wrote on 5/13/2009, 1:50 PM

I had not but just submitted the following:


A link to the thread in the Sony Forums about this is below. I'm getting weird playback issues. At times it becomes out of sync, where the video actually appears to be moving in slo-mo and not at all with the sound. It appears to get worse over time, almost like a memory leak or something. Additionally it may show red or black frames for portions of the video for entire clips or sections. At times it will also not show effects even though effects are toggled on. Magic bullet may be an aggravating factor but hard to tell.

The project is 1080p, source files are mxf from a Sony EX1. I originally worked on this project in Vegas 8 without issue.

I am running Vista 64-bit. Intel Core2 Extreme CPU X9640@3.00GHz with 8 gigs of ram. I am using the 32 bit version of Vegas as I require Magic Bullet which is not yet compatible with 9 64bit.

Thanks;

only other thing I can even kinda think of is that V9 now has multithreded render for playback enabled by default, so you might want to see if disabling that in the hidden "internal prefs" tab does anything to help.
