When editing AVCHD 1920x1080 60i no filters, no transitions, preview window skips frames and plays back choppy. Here's what I have tried. I match my media setting automatically in project properties. I tried changing preview window from best, good, preview and draft and also changing from half, full and auto in all four settings. No difference. I have (simulate device aspect ratio) plus (scale video to fit preview window) unchecked. The preview window frame rate stays locked on 29.970 regardless of any of the settings I tried. If I start using filters or transitions then I will drop in frame rate which we know is normal.
This problem of choppy preview playback also happens with sd mp2 footage but not as bad. I also tried pre rendering the avchd clip as .avi NTSC DV widescreen it's much better but still has some frame skipping in preview with out losing frame rate.
Playing back my avchd & sd clips in windows media player and Cyber Link Power DVD-10 both clips played back smooth. In VLC media player the avchd clip played back choppy and was about 25% worse then my Vegas preview. The sd clip plays back fine in VLC.
With Vegas loaded in pause mode my CPU usage is "0" when playing my avchd clip the cpu usage is between 15 and 20% and only 4 treads of the 8 are being used.
I have tried setting dynamic RAM preview to 0, 256, 1000, 2000, 3000, 4000, and back to normal 256 no difference in preview. I also Played around with maximum number of rendering threads no help. I also went into the internal settings or some people might call it secret menu or factory settings. I checked to make sure (multi-core render for playback) was set to enable or true it was.
I updated my Nvidia GeForce GTX470 video card driver from 331.65 to 331.82 no difference.
Two weeks ago I update my M/B bios no difference.
Here's my system info.
Windows Version:7 64-bit
RAM: 24 GB
Processor: Intel i7-950 3.08GHz
Video Card: EVGA GTX470
M/B Asus Sabertooth X58
Monitor #1 View Sonic VX2235 for timeline.
Monitor #2 Lenovo with IPS screen 1920x1080 for preview.
Video Capture: Card Reader USB & IEEE1394
CD Burner: Lg DVD-CD Burner
DVD Burner: Lg Blu-ray burner
My question is with my system should I be getting a clean smooth preview when the frame rate is locked in and not dropping?
Does anyone on this forum have any recommendation on how to improve my preview or is this the best I should expect from my system with vegas pro-10?
