NLE: Vegas 8,
Camera: Sony FX1
Video Specs: hdv 1440x1080 60i 29.97fps mpeg2
*Disclaimer*: I have scaled this same source to 1280x720 and encoded it with otherwise identical avs and x264 settings, bobbed etc, and it replays perfectly on the same machine that the 1920x1088 freezes on.


Video data is sent to Megui through Avisynth and gets encoded with x264.



Here are the x264 encoding setting:
===
--crf 26 --ref 16 --mixed-refs --no-fast-pskip --bframes 16 --b-pyramid --b-rdo --bime --weightb --direct auto --filter -2,-1 --subme 7 --trellis 2 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --me esa --threads auto --thread-input --progress --no-dct-decimate --no-psnr --no-ssim --output "output" "input"
===



Here is the avs file:
===
AVISource("C:\_VIDEO WORK\6444\frameserve\6444.avi", audio = false)
LeakKernelBob(order=1, threshold=10)
lanczos4resize(1920,1088)
FFT3DFilter (sigma=1.9,sigma2=2.55, sigma3=2.95,sigma4=3.90,bw=16, bh=16, ow=8, oh=8, sharpen=.8)
ConvertToYV12()

After encoding this 9:24min long video for 23 hours (!!) as 1920x1088 bobbed it will play for 3 seconds in VLC Player and then freeze and intermittently every 20 seconds or so display the video in a corrupted fashion again for a few seconds and freeze again, continually behaving this way. I am playing this on a intel C2D 3ghz 2gb machine. My cpu usage never goes above 50%.

When checking View> 'Stream and Media info', then the 'Statistics' tab in VLC player, the 1920x1088 video freezes more at times of higher stream bitrate, ie over 6000kb/s. However, the smaller encoding scaled to 1280x720, bobbed, and encoded with identical x264 settings will never freeze even when stream bitrate gets near such kb/s.

Is my issue an encoding problem? Or is it a replay problem (again, which I find unlikely given my machine specs and minimal cpu usage)?
Why does the 1280x720 encoding replay flawlessly, yet the 1920x1088 freezes?

TIA.
