32 bit runs more smoothly than 64

jwcgc629 wrote on 8/1/2012, 4:39 PM
I have the latest builds of both 11 32 bit and 11 64 bit, but recently, the 64 bit version has become so unstable that I can barely use it to edit. Seems when the program is first opened, the timeline plays fine, but after about 30 to 60 seconds of playback, it begins to stutter to the point it becomes a series of stills....Even a low playback resolution and quality, the problem seems to get worse the longer I use it.

As a test, I started running the 32 bit version and it seems far more stable than 64...just wondering if I am alone, of if others are experiencing the same issue....and why ? Thanks

Chances are you are in a crowded room with thousands of users - BUT FIRST - state your case -
Version of VegasPro including build number?
YOur PC platform specs?
What's on your timeline?
Are you connected to Wacom tablet?
Are you using GPU or CPU?
Are you using Win7-64? OS?
Compatibliity MOde for Win 7 turned-on?

Same conclusion here. I get better stability with certain plugins with the 32 bit version over 64 bit.

Y'all got separate TEMP file locations (and maybe even duplicate project folders) for V11 32 and 64 bit versions ?

I won't contest the idea that VP32 might be more stable, but I'm not seeing what you're describing. At least not with a basic test.

I took about 240 DVCProHD 720p/23.976 fps quicktime clips (it's what I had) and dropped them on the timeline. I had set Vegas' prefs to make 2 second crossfades between each clip. I set vegas to play it and then started typing here. 5 minutes later and it's still churning along.

This isn't demanding footage, nor is it a demanding timeline. Just crossfades.

My system setup here is:
VP11-64 b683
Core2 Duo 8400 (3.0GHz)
6 GB RAM
--Preview RAM is set to 500MB so subtract that from the total RAM since Vegas can't use it for processing.
No GFX acceleration
No Wacom tablet has ever touched this PC
Preview setting was Best/Half for 9 minutes. I just switched to Best/Full and continued for another 4 minutes.

To me, it sounds like you're running out of memory after 30-60 seconds. How much RAM do you have and what's your RAM Preview setting?

....As I stated in my post....the latest build of both 32 and 64....
Dell Studio XPS i7 2.6 ghz, 24 gb ram
SD footage.....preview set on good/half...
Dont know what a Wacom tablet is...
Have been using GPU accel....cant see any difference with it on or off...
64 bit version of 7
Not sure about compatibility mode...how do I check ?

Pro 11 is by far the most troublesome version of Vegas I have used to date...and Sony customer support is non-existent for all intents and purposes...

Rob,

I have RAM preview set on 5000 mb...then again, I have 24 gb of RAM....and it seems it would run out more quickly in the 32b version since I would assume it cant access the entire 19 gb of remaining ram......

I did recently run a system optimization with Iolo System Mechanic and the issues seem to start after that....Im wondering if it changed something that is affecting the 64b version of Vegas...

Yeah, you'd think that there's more than enough RAM available for Vegas' operations + the 5000 MB sequestered for RAM preview. And yet you play the timeline for 30-60 seconds and Vegas 64 starts to slow to a crawl.

What I should have done was to set my own preview RAM to 5000MB. I could just manage that on the home PC which has 8GB installed, but I'm leaving for a few days and wouldn't be able to follow up here. However, I predict that I wouldn't have the same problem and that's probably because of my choice of media. The DVCProHD files I'm using aren't long GOP. If they were then I'd probably need to be able to decompress 15 frames into RAM to see any one frame. 15 times the memory usage. Assuming a 15 frame GOP. Vegas would be stashing a lot of frames in the preview RAM.

Several people here have computers with 24GB installed. I can't remember anyone every saying that Vegas had used all that RAM. I'm guessing it can't, and I'd probably try reducing your preview RAM even though you have oodles of RAM installed.

As for Vegas 32 performing better...it's been around a lot longer, the parts might have been better debugged, the 64bit code might have been built starting with the 32-bit code... and so on. Also, you're probably running 32-bit Vegas on 64-bit windows. Maybe the fact that its forced to stay within 2GB of memory helps rather than hinders. Or maybe 64-bit Vegas is still relying on a 32-bit library or codec for what you're doing.

Last point before I go. SCS tech support for Vegas is non existent. You're right about that.

Wow, 32GB of ram...

I use V9 on my 32 bit system with 2GB of ram. RamPage shows Vegas never uses more than ~300MB during a render. And that's with no paging file on the system, just ram.

I must be doing something wrong. System runs great, has run great for years that way. /snark off/

Take care - in many cases it has been seen that more Preview RAM than some 5-600 MB - even more than 75-100 Mb in special cases - will slow rendering significantly.

Wow. I could almost cry tears of joy.

I have been plagued with V11 crashes, choppy, playback, freezing, etc, since I bought it a few weeks after release. It has been so bad that I have had to resort to using Movie Studio 11, to do my edits, and then port to Vegas Pro to do the things not available in Movie Studio. Naturally, running a high spec Win7 -64bit machine with 16gb RAM, I figured the 64bit version of V11 was the way to go. Apparently, this is not the case.

I installed the 32bit V11 and everything is running like a dream...Oh the pain and frustration I could have avoided...

Just wanted to post this for others that may find their way here suffering the same problems I have.

I know exactly how everyone feels about this. I've spent a good deal of time recently trying to get smooth playback in Vegas 11 64. Problems solved with 32.

Strike me that in 64 bit Vegas Sony are marketing a substandard, redundant package. Unless they really don't test the software before it goes out the door then they must be aware that it fundamentally doesn't work.

How can you be expected to edit footage without playback?!

But 32 bit works like a dream :)

Thanks.,.....I feel a bit better, guess....at any rate, I keep trying 64 thinking something will have magically corrected itself each day when I go into the studio and re start my NLE system....but NOOOOO....64 runs as badly as ever, appearing to be "clogging up" as playback progresses. This isnt really a rendering speed issue (most of my work is 30 and 60 second broadcast spots)....it is the choppy playback that degrades into what looks like a spastic slide show.....32 seems to work fine.
Now, if I could figure out the odd black lines that appear (in both versions) when using zoom and similar transitions....If I play with the zoom speed, I can sometimes eliminate them, but this has been going on since I "upgraded" to 11.....
