Hi all
I'll try to be concise as possible with this post but there are a few variables so bear with me. Here are my specs & installed programs:
quad cpu @ 3.78ghz
2gb RAM
ATI 5850
Windows 7 pro
ffdshow rev 3342
mpc-hc rev 1774
Standalone filters registered: Matroska muxer; Matroska source; Matroska splitter; MPC - Mpeg source (gabest); MPC - Mpeg splitter (gabest); MPC - Mpeg-2 video decoder (gabest); MPC - Video decoder
Sources: blu-ray VC-1 m2ts files
I am having a problem trying to encode VC-1 video sources with avisynth & MeGUI inside Windows 7. Basically, regardless of encoding settings, the result is always slow, choppy video (as if frames are missing- sample below). I say that the problem is related to W7 because in XP I never had any such problems with the same settings/sources.
I can load the vc-1 source in avisynth script creator in MeGUI perfectly fine. I save it, then I see what the result is when I play the .avs file with mpc-hc. The choppy playback resumes, regardless of the decoder used: have tried it with libavcodec or wmv9 with ffdshow; or with mpc-hc's internal transform filters. So, having played around and tested this, I can safely say this is a encoding problem with the vc-1 source and avisynth in W7.
Doing a bit of net searching, some people believe that there is indeed a problem with vc-1 & avisynth in W7 but there appears to be no apparent solution (as far as I can see).
So, attempting to sum up the problem: can't properly encode vc-1 sources without slow/choppy playback (via avisynth & megui); no errors whatsoever when making avisynth script or during encoding; all other video encodes (avc, x264 etc) turn out fine.
Here is a sample of an vc-1 encode, it's only 18mb:

It might just be better to take a look to see what I mean. This is basically what all my vc-1 encodes turn out like.
Any help appreciated! :thanks:
PS- My simple avisynth script for *most* encodes (depends on aspect ratio):
DirectShowSource("E:\Blu-Ray Rips\tbe.m2ts", fps=23.976, audio=false, convertfps=true)
#deinterlace
#crop
#resize
#denoise
My x264 encoding settings:
program --profile high --pass 2 --bitrate 10000 --stats ".stats" --thread-input --keyint 240 --min-keyint 24 --bframes 5 --ref 6 --me umh --direct auto --partitions all --output "output" "input"
