Treating captured video

[MarcN]

Hello!

I’m regularly capturing from TV (PAL) with VVCR. The video is compressed with PICVideo MJEPG. So far I did use Vdub for postprocessing but now I want to switch to AVIsynth. However I ran into two problems.

1) Most deinterlacer filters (like LeakKernelDeint) I tried produced noticeable artefacts in high contrast (horizontal) areas. See below:

What filter would you recommend for this?

2) The capture guide says in its postproscessing section for Vdub:

In general, one should apply a temporal denoiser first, followed by a spatial denoiser (with low settings) which cleans the remaining artefacts.

In the same section for AviSynth I found this example:

…
VagueDenoiser(threshold=4, method=1, nsteps=6, chroma=true)
TemporalCleaner(6, 12)

But that’s the reverse order of what is recommended in the Vdub section, isn’t it? So which filters should I use and in what order?

Thanks a lot, Marc.

Try TomsMoComp() for your deinterlacing.

Regarding filter order, it did say "in general". You'll soon find out that there are few, if any, hard and fast rules. Try things, and if you like the result, stick with them. Different people like different things, and all filtering involves tradeoffs.
