Vegas Pro 12 – Preview Lag
I know that this question is asked too often as it is a common issue within Sony Vegas, but it is really bugging me now. I have a good desktop primarily for HD video editing. Here are my specs:
– Intel i7 3770k @3.40GHZ
– 16GB DDR3 Ram
– Nvidia GeForce 560ti (1GB)
– 2TB 7200rpm hard drive
I have been working on Vegas for a number of years now and I have just about had it with the preview lag which completely slows down my workflow. I have begun editing with Cineform in an .avi container to see if it would make a difference – it did help slightly, there was less lag. Does the issue lie with my graphics card – it’s not top of the range? Or is it something else? As soon as I even add a fade or any other effects to clips the preview begins to constantly skip frames. It would be great to hear your thoughts. PS: I usually work with 1080p footage. Cheers. -

You list one hard drive. Is your media on that same drive?

That’s how Vegas is Scott, once you add multiple effects/filters
you are gonna experience playback lag. What you can use is the
Dynamic Ram Preview feature.Steve Rhoden

Hi Graham, thanks for your reply. Yes, I have all of my programs installed on this drive along with my media. Would it be a better option to invest in an SSD primarily for the programs and use the 2TB drive just for the media? Thanks

Hi Steve, you are right with this but I am literally adding one effect to a clip and the framerate drops completely. I started working with the NewBlue Titler Pro plugin and the preview window is literally showing freeze-frames – 1 every few seconds, which makes editing very hard. I’m constantly having to pre-render parts of the timeline to see an edit which completely slows down my workflow. Is my PC at a high enough spec? Or is this a Vegas problem? Cheers

If you’re using a GoPro, the mp4 files it produces will gag with vegas11.
Also, do you have your preview set for “auto”?Roger Bansemer – PaintingAndTravel.com

Hi Roger, No it depends on what project I’m working on – sometimes it’s Canon 600d (T3i) footage and other times it’s footage that’s already been provided in various formats, but I haven’t worked with GoPro footage before but instead use their Cineform codec to transcode other media to .avi. I’m working on Pro 12 at the moment and I’m virtually always on preview (auto) or even draft for some projects still with consistent preview lag! Have you had similar issues? Cheers

Experiment with lower quality/size in the Preview window, and also do not use “auto” for the window size. That eats up CPU. I know it is frustrating to not see sharp detail in the preview window; when you need that do a bit of Dynamic RAM preview
Run Process Explorer to see where your bottleneck is – CPU or GPU.
Good luck,
Steve

Multiple drives are essential.
I use external drive bays (such as Nexstar) for SATA drives that hold the source media, and an internal Seagate SSD/platter Hybrid drive for Vegas temp files (set this location in Vegas). This way, Vegas is never writing different files to the same drive at the same time.
Try an SSD for your OS and the drive where Vegas runs. Buy something like a Corsair Neutron GTX for Windows. That will free up your 2 TB drive for the temp files.
These little babies are lifesavers – let you buy cheap bare SATA drives and swap them at will:

Back in the Day (!) I used to edit on a DELL Schlaptop. Sure, it has a fair-sized drive, but as soon as I liberated its single System drive by adding 3 additional drives via something like this PCMCIA Multiple F/W adaptor. I was able to run external drives AWAY from my system drive, Vegas just flew! But then I got my first Tower PC with 5 internal drives . . . . I’m now on my 2nd Tower PC and Vegas is like running Microsoft WORD – mostly!.
