  Component bottleneck for real-time preview in Premiere Pro CC?

  Posted by Dylan Mann on February 2, 2016 at 9:59 am

  Hi there,

  My specs are as follows:

  i5 2500k @ 4.8Ghz
  4 x 4gb = 16Gb DDR3 Ram in dual-channel
  GTX660Ti 2Gb VRAM
  1TB Samsung 850 Evo SSD x 2 (1 media, 1 OS)
  Premiere Pro CC 2015

  Sometimes when editing 1080p videos from my GH2 or 4k videos from my smartphone (S6), it lags a little initially and I have to pause it before it plays back smoothly all the way. This happens regardless of the playback resolution (whether it’s 1/4 or Full, doesn’t matter).

  What is causing that initial lag and shouldn’t the lag be resolved by itself instead of me having to pause it first for it to go on smoothly later?

  This happens to simply trimmed videos with 0 VFX/SFX too.

  If you don’t want to buy a faster processor you might want to try and transcode these to DNxHR.

  is this really a processor issue? I’m asking because there is just the initial pause/hesitation, and it can handle the previews nicely thereafter.

  My off-the-top of my head guess is that it takes a second to decode the h264 and put it into ram or some sort of cache or preview, which is why a cold start on a clip may take a second but giving it a moment to load it may not.
