MOV to Mpeg4 using Avisynth and MainConcept

[RazorHolt]

Hello everyone,

I'm trying to encode a MOV file to mpeg-4/H.264 using Avisynth and Mainconcept Mpeg4. I use Avisynth to add a logo and also to resize the video.
I've tried many AviSynth filters to improve the quality of the encoded file but I'm still not very impressed.

File Input: MOV, 44MB
File Output: Mpeg4, 17MB (size desired)


Avisynth script:

LoadVFAPIPlugin("C:\Program Files\AviSynth 2.5\plugins\QTReader.vfp","QTReader")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\ColorMatrix\Release\ColorMatrix.dll")

video = QTReader("C:\movie\mymovie.mov")
video = video.FlipVertical
video = video.BilinearResize(800,450)
video = video.colormatrix()

logo = ImageSource("C:\movie\watermark\logo.png")
logomask = ImageSource("C:\movie\watermark\logo-mask.png")
Overlay(video, logo, mask=logomask)

My questions are:

1. Is there any other filters I should add to pre-process the input file?
2. Is my MainConcept software properly configured?


Thank you very much for your help .

tests with some filters in post #4.

avisynth 2.5 have "auto load" and when the filter is inside the AviSynth 2.5 plugins folder,is not needed to load any filter with command lines like:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\ColorMatrix\Release\ColorMatrix.dll")
only put all filters needed inside that folder.

and if needed,read in the faq "Q1.15: How do I use a plugin compiled for v2.0x in v2.5x ?"

Thanks Jeo for your reply.

I spent the whole week-end trying the filters that you recommended but the results were the same. I think that Mainconcept is not really appropriate for the encoding in high rates.

In fact, I get a better image quality result with WME. The fade in/out are horribly handled by Mainconcept, in high rates at least.

So, is wmv the best container for streaming in high quality?

i never did a single wvm encode and don't know the quality but mainconcept is not good.
i'm sure that tmpgenc is really better(or CCE).

i'm not expert in avis or wmv files(or other).

hint: read the LT. Columbo guides,he have extreme knowledge and will help you more than i.
