MPEG-1 Improvements....Suggestions?

[oscdude]

I encoded a video in MPEG-1, 1600kbits/sec.
I used avisynth:
AVISource("C:\Captures\cap.05-06-03_08-44.00-CDV.avi")
ConvertToYV12()
LanczosResize(352,240)
MSmooth(threshold=5,strength=3,debug=true)
ConvertToRGB()

Here is a sample of the video:
http://shakirafan.isurf.ca/sample.mpg (7mb) - right click & save

During playback the video looks still a bit blocky and blurred when camera zooms out. Any suggestions as to how to better my video. Anyone know of any filters (avisynth or virtualdub) that can improve the visual quality and controls the blockage better? Or is there no hope at this bitrate level.

Thanks in advance

Any reason why you chose Mpeg1 over Mpeg2 ?

Is the source AVI free of artifacts ?

If it is a VCD you're trying to make, I believe your bit rate is too high to be standard.

Which Mpeg encoder are you using ? Try Quenc 2 pass.

Use DGmpgdec as an AVISynth plugin. Even if you don't have an MPEG source file, it still has a very good deblocking function in it (borrowed from h264). http://neuron2.net/dgmpgdec/dgmpgdec140b2.zip

Also, use Undot http://mywebpages.comcast.net/trbarry/UnDot.zip


loadplugin("undot.dll")
loadplugin("DGDecode.dll")
AVISource("C:\Captures\cap.05-06-03_08-44.00-CDV.avi")
ConvertToYV12()
Lanczos4Resize(352,240)
Deblock()
Undot()

If you're still not happy with that, check out FFT3Dfilter. That's a great AviSynth cleaner, but I'm too lazy to go into it. http://bag.hotmail.ru/

Read the whole page. There is an additional dll you'll need to download to make it work.

Try this for starters

FFT3dFilter(sigma=2.0, plane=0, bt=2, bh=40 ,bw=40, measure=false)
FFT3dFilter(sigma=3.0, plane=1, bt=2, bh=40 ,bw=40, measure=false)
FFT3dFilter(sigma=3.0, plane=2, bt=2, bh=40 ,bw=40, measure=false)

If for a VCD, use VCD encoder defaults.

If for a DVD, up to 1.856 Mbps (1856 kbps) MPEG1 can be used but audio needs to be 48k MP2.

I do prefer mpeg-2 but I am working on mpeg-1 in this one. Yeah the mpeg-1 I am working on is not standard. I'ts a xvcd, I guess you can call it that.
