Hi there
I have a anlaloge capture card on my Pentium4 WinXP SP1 system and i am usually using AviSynth to process it (deinterlacing, denoising, cropping, resizing) and then encode it in VDMod or Helix producer.
Now i wanted to test ffdshows filters for processing the clip to see how fast they got thanks to Andys asm tunings. But i have problems deinterlacing the captured clip properly.
Latest ffdshow-20040701b_SSE2.exe is used.
The clip to be processed is a capture that I have already encoded with AviSynth and VDMod. So i know that i have to swap the filds and then set buttom fild first to get nice looking progressiv frames.
However when using ffdshow, i will not get rid of the combs or get a nice looking frame.
I load the captured, interlaced clip into VDMod and choose fast recompress. Under compression ffdshow is seleced. In the input section i can assume interlaced material or not, that does not change anything.
I enable image processing an then choose configure:
1. Move deinterlacing to the top. Processing whole image, swap fields, choosing median or kerneldeinter in all combinations gives bad resuts
2. Blur & NR: denois3d & HQ
3. Crop: cropping even numbers on left, top, bottom, right
4. Resize & Aspect: Spezify size (Modolo 16, e.g. 640x356), Resize always, No aspect ration correction.
Any hint what i am doing wrong here?
The output will show some diagonal lines like stairs, others are OK, round holes in the backround will always get those stairs.
