I need your help, again :)
I have a noisy SD capture in MPEG-2, about 42 mins, about 2.5 GB.
Then I use Xvid 1.2.-127, Dec 8, 2006 (as supplied with AutoGK 2.40) with VirtualDubMod 1.5.10.2, build 2542, Xvid all settings default, target quantizer=2, threads=2, single pass. The trouble is, the capture is noisy. So I play with DegrainMedian here and there and the result with TQ2 is about 1350 MB, resolution 720x576, 25 fps. Sometimes when the captures are not noisy, I'll get about 800 MB, which is okay for me.
I am willing to go down to 640x480, 25 fps, about 700-800 MB, single pass, but I do want to get it also from the 1350 MB AVI, not only from the original MPEG-2 file. I know that each recompression is not good quality wise, but they were noisy, so I can accept this.
The trouble is:
1) I would like to perform a quick check of the target Q2 size before doing the whole 42 mins MPEG; I know it is SelectRange (?) but don't know exactly what else I need to put into AviSynth and how long does the range have to be for it to be accurate.
2) I would like to redo the 1350 MB as described above, when messed up, into something 800 MB sized, so I would like to ask for some denoiser suggestions enabling me to do this conversion
720x576x25->640x480x25 (42 mins) (1350 MB->800 MB)
Thank you for pointers.
