Very Slow X3 on 64bit Win7

[ladyluckmedia]

I've just been testing out the new X3 Video Studio and I was wondering if I have missed some settings somwhere.

It's running horribly slow, I was kind of expecting it to be lighting fast on my machine, which is a 8 CORE processor with 12GB ram on Windows7 Ultimate.

Is it me, or have other people experienced this slowness on their systems as well?
Very very slow.

Welcome to the forums,

First are you talking about the Advanced Editor, which is VS Pro X3? The Easy Editor is an entirely different program called VideoStudio Express 2010. This along with DVD Factory 2010 are going to be sluggish due to the background cataloging, especially so if you have hundreds if not thousands of videos, images, and audio files on your system. VS Pro X3 however does not seem to run slow on my antiquated WinXP machine.

One other thing we need to consider is what type(s) of video files are you attempting to work with? DV or some other Standard Def, or some Hi-Def files like AVCHD?

Hi and thanks Ron

Yes, I'm using the Advanced editor the Pro version.
I'm importing HD files from a samsung camcorder.

Unfortunately ProX3 doesn't read the mp4 files created by the Samsung, so I have to use the Samsung software to first convert the files into either a WMA format for the highest quality, 1920x1080, or there are lower resolution mp4 conversions at 1280x720.

Once converted, ProX3 can read them ok. However working with these files is like watching paint dry, it's sluggish and slow and just doesn't seem to like it. Perhaps I'm missing a setting? It can't be the computer, it's powerful enough to handle it (at least I would hope so).

thanks in advance.

When you say "However working with these files is like watching paint dry, it's sluggish and slow and just doesn't seem to like it." What exactly are you trying to do? Inserting transitions, using the PIP feature in the overlay track? How many clips of what duration have you loaded to the timeline? Also it would be helpful if you right click on one of the clips in the timeline and click "Properties" and post the full details here.

Ok, sorry I should be more technical in my explanations.

Ok, so the files I'm dealing with are MPEG-4 files, H.264 Baseline Profile Video, 24bits, 1280x720 16:9, 50 fps, 9729kbps with MPEG AAC Audio at 48khz 16bit stereo, 128kbps.

It's slow doing everything. It's slow when I preview a clip, it's not an instant start. It doesn't immiediately track mouse clicks when I'm trying to manipulate clips and moving the front and end markers to get a perfect edit.
It's slow to render. It can barely manage project preview when I'm cutting and editing 8-9 clips together to make a 6 minute presentation video with a few transition and video effects, and background music. The Project preview is really slow and it is jerky so I don't really even get a low res "preview" of what I'm trying to achieve.

It's just all a bit frustrating as you can expect when I'm running such a high end PC, I'm expect no delays in anything else.

Is is something I'm not doing right?

thanks in advance.

I also forgot the mention, I've also got a ATI FirePro V8700 FireGL graphics card which has 1GB graphics memory!

Is Smart proxy turned on or off in your settings?
Try turning it on.

Under Preference (F6) -> Performance.
Turn on Smart Proxy, Auto Generation and Hard Decoder Acceleration.

Disable Hyperthreading helps.

Video Studio is still a 32bit program and will not use any more than 3.2gb of ram.

Processor is what will make it appear to run faster.

I have done numerous test on attempting to get VS to run faster.

Results are posted in another thread.

Having a half decent video card with a couple of gb of ram seems to help as well.

I think I know what's happening -we have a fix coming out shortly for MP4 file support and what you're describing is a symptom of the problem.

I want to share recent findings related to performance. I have a cpu intensive application I developed. I compared this app running in an old laptop with a fast but single core chip and with 1 GB of main memory running XP, with a very recent Dell pc with i7 cpu and 12GB of main memory running Win 7. This app shows cpu run times in the laptop almost half the run times in the "fast" pc.

After much experimenting (turning Hyper-threading off, assigning cpus to the app, etc), the highest CPU utilization on the "fast" i7 pc is 25% (exactly one of the four cpus this chip has). On the laptop, this app shows 99% cpu utilization. Thus 100% cpu utilization of the same speed chip works better when the app has the entire chip working, vs 25% of the same speed chip.

I think these new multi-core chips can actually perform slower in high cpu intensive applications, like when rendering a project in VS... Al

Try this
Start
msconfig
Boot
Advanced options
Numbers of processors
Change it 4 or 8 depending on cores
Restart

That's a new suggestion to me and I was looking forward to doing it. Thanks for posting it. However, I have not observed any change. What exactly is your suggestion supposed to do? I can't imagine may users knowing about your suggestion... Al

Normally the PC is set to boot with single core. Other cores "kick in" once the demand on processor increase. By starting all cores at the same time makes PC run faster

I am having the same issue. Slow to preview files. choppy video, audio. Using a HP dv7 8 gigs of ram. I know its not due to low memory or slow processor. Did we find a fix for this issue? Thanks.

Please start a new thread and give details of your project, and maybe we can help.
