Wondering where the bottle kneck is on my system?

Ive been a Vegas user for about 3 years and just recently added Magic Bullet Looks. I love it, but when I add the effect, the sound and video never sync up and is jittery. This happens when I add a New Blue effect as well. I thought this was a RAM issue, so I upgraded from 8 GB to 32 GB. Yet, I still get the same effect.


All of the footage is from my 7D. No conversion.

Here is my setup


Intel Core i7-2600K unlocked 4.6
ASUS P8P67 Pro B3 Motherboard
windows 7 64 bit
corsair dominator 32gb ram ddr3
nvidia card 1gb geforce 5 series ( i know, old)
A couple of standard segate 5400rpm hard drives


Do you think I need a faster HD or a more capable video card? It only doesnt this when I add effects.
 
Wow, from 8GB to 32GB with the same result? And you've got a screaming fast CPU in there as well.

Hate to say it, man, but I highly doubt there's anything you can do, except maybe upgrade those Seagates to 7,200. But that wouldn't fix your issue.

Frankly, I have no idea how well optimized Magic Bullet is under Vegas. I do know that it won't use your GPU to accelerate itself (doesn't even do that under Premiere with CUDA). You might get a bit better performance from a video card, but I wouldn't go much higher than a 280GTX, which you should be able to snag for around $100 or less.

Will Vegas give you an intermediate render when you apply effects? It's been so long since I worked in Vegas.
 
What codec is you material?
If you use AVCHD or something similar complicated, the whole power goes to encoding.
Try to render something in Cineform, motion JPEG or DNXHD and see if that makes a difference.

Magic Bullet does a lot of really intense calculations. Are you expecting real time playback after dropping the effects in? No matter how beefy your system gets, 1/24 of a second isn't very long for the computer to calculate all of the changes it needs, especially when it already has to calculate how to interpret the heavily encoded files from your 7D. Your best option is to render before preview.
 
I get realtime preview, as long as I don´t stack too much effects, but colorista and Looks work.
But only on intraframe codecs - on long GOP or interframe stuff it doesn't work, though I have a macho workstation.

.mov/straight from the 7D. Ill try some of your suggestions yall. I appreciate it
 
Its def is that Vegas 10 that has the issue. I just loaded the same file with the same look in Premier on my computer and it played back instantly.I'm tempted to upgrade to 11 to see if it works better with MB..
 
Premiere has the Mercury engine which has a different type of playback. In Vegas were you watching using Preview/Good/Draft...?? Upgrading to 11 MIGHT help, but it also might not. Try the demo! If your video card is supported then 11 might improve your performance dramatically. Just remember that the Mercury playback engine in Premiere isn't a 'raw' playback. You'll see blocks in parts depending on your footage and settings. Preview might have been smooth but did it 'look good'...?

5400rpm is your first problem. You need 7200rpm harddrives for video. I have a very similar Dell core i7 system, and I edit alot of high-end hacked GH2 footage. Lots of interviews, concerts, so forth. I can't view any footage with Looks on regardless of how light I stack the plugin.

Everyone has his/her own preference... Personally I edit all my footage, grade, then render. I don't need to see my grade in order to edit.

One note... The next workstation I build will have a nice RAID setup with dual sata drives, tons of RAM, and the most impressive Nvidea card I can fit in my machine (considering the power supply). A high end Core i7 is assumed on my part, but if there is something better by summer I will jump on that as well.
 
When you talk about building your next work station, will it predominantly be built for Vegas? I'm trying to order a sufficiently fast computer in the next couple days and need some input as far as processor speed, graphics card and ram go. I shoot on the Panasonic Ag-AC 130 in the AVCHD codec. I know this codec is pretty hard on processing power so what is the minimum that I should look to get? 3.4ghz quad-core?

2nd biggie... when it comes to Vegas which is the most essential ingredient as far as rendering goes, ram or graphics card? Im not doing much (if at all) graphics work with AF and would mostly be used to edit and burn weddings. I don't need this thing to run NASA just an adequate computer that will handle AVCHD and Vegas. I don't have the cash for all the high-end parts so I would like to skimp where I can and splurge where I should.

Please and thank you in advance.

Vegas can optimize render times (and some playback) based on your card. See details here. Quote off that page...

NVIDIA
Requires a CUDA-enabled GPU and driver 270.xx or later. GeForce GPUs:
GeForce GTX 4xx Series or higher (or GeForce GT 2xx Series or higher with driver 285.62 or later).
Quadro GPUs: Quadro 600 or higher (or Quadro FX 1700 or higher with driver 285.62 or later).
NVIDIA recommends NVIDIA Quadro for professional applications and recommends use of the latest boards based on the Fermi architecture.

AMD/ATI
Requires an OpenCL-enabled GPU and Catalyst driver 11.7 or later with a Radeon HD 57xx or higher GPU. If using a FirePro GPU, FirePro unified driver 8.85 or later is required.


Those cards will improve your entire experience in Vegas, but you need to have a power source in your workstation capable of handle the cards. RAM makes a considerable difference (especially the speed over the amount). Your graphics card, due to the new GPU integration, DOES make a considerable difference, especially in rendering.

As to dealing with the codec... AC130 is a solid camera but the codec is not insane. I'd say most of the hacked GH2 stuff is of insane bitrates in comparison. 16gb gone in 20 minutes... Thats a heavy codec. Right now I'm running a Core i7 at 2.8GHz, 16gb ram, decent ATI card with dual monitors. It runs great for most projects but with the heavier codecs it drags a bit on multi-cam (4) editing. Which is why I am upgrading this coming month.

In terms of NLE I am using Vegas for most of my work but will be migrating to CS6 by the end of the year... Slowly adding in AE right now. The Mercury engine in CS5 is very impressive. Works with more cards than Vegas' current GPU implementation.
