  Sony Vegas Pro 13 – Preview Lagging

  Posted by Farhan Ali on June 9, 2014 at 2:53 pm

  Hello everyone hope you’re well, for some reason when it comes to previewing my projects it seems to lag at some point or at times lags from the beginning.

  I have the following specs:-
  OS – Windows 7 Ultimate 64-bit SP1
  CPU – Intel Core i7 4770K @ 3.50GHz
  RAM – 16.0GB Dual-Channel DDR3
  Motherboard – ASUS Z87-PRO
  Graphics – NVIDIA GeForce GTX 780 3071MB

  The videos that are being added onto my projects are:-
  1920 x 1080
  29 fps

  Surely my desktop pc spec are high enough to be lag-free?

  Thanks

  System specs should be fine. What type of drive is the video footage residing on, and is it a physically different drive than the system drive?

  The more filters/effects you place on your events (mostly on HD)
  on the timeline, the more it lags during Previews… Nothing is
  wrong, that’s just the way Vegas functions.
  The Dynamic Ram preview function comes in handy here however.

  Hello Dave & Steve thanks for your response.
  @Dave, All my project files are on SATA HD’s they also get rendered on the same HD.
  @Steve. To be honest I don’t use any filters/effects I only “Disable Resample” the videos and at times add audio commentary. What should the Dynamic RAM Preview be set on?

  Thanks

  dynamic ram preview renders the looped section of the timeline to your RAM…. so you set it based on how much RAM you have and how much your machine uses for other tasks.

  It will playback smooth even if you add a ton of filters since it is pre-rendered. This is where having 32gb – 64gb of RAM is a huge benefit.

  If your not adding overlays, effects or transitions than I am not sure what is going on here.

  Try disabling your GPU in the options and only use the CPU and see if it improves.

  If it does, make sure your drivers are updated and try it again.

  I have seen a poor quality PSU cause the GPU to be under powered therefore throttle the card and decrease gaming/rendering performance without the user knowing

  Also is your media on the SD card, Hard drive or SSD? that could be your bottleneck….
