help for bad video (captured from tv)

[byme]

in first, sorry for my english

is a time that I'm stuck
I have videos of 720x576 by resizing to 1024x576
and, even after filtering, the quality is always very poor

I only have the videos already deinterlaced

I have so many similar videos
put this as an example

you have any suggestions or a spell to Do?

Start by deblocking. Deinterlacing that video was exactly the wrong thing to do -- it was progressive video with fields out of phase. You just need to get the fields back in phase with TFM(). Too late now.

@jagabo, how would one correct that 50fps AVI and restore the original frame structure? Or...would one have to revert back to the original, unprocessed recording as the only alternative?

BTW, in the AVI the highlights are blown out in the chroma planes and gamma is too high. IMHO. Looks a little washed out. It just might have originated that way.

@jagabo, how would one correct that 50fps AVI and restore the original frame structure?

It depends on exactly how it was deinterlaced. Something like:

SeparateFields()
SelectEvery(4,0,3)
Weave()

would work if the deinterlacer started with one field then interpolated the other.

Or...would one have to revert back to the original, unprocessed recording as the only alternative?

That would be best.

I figured. Thank you.

Screwy levels always bug me. The following helped keep me awake for an hour during a rainstorm here today. Couldn't figure why the AVI images are so bright and thinned out. A little COlorYUV and ColorMill made the gals look much better (and I forgot about the rain for a while).

Frame 32, original. Too blue. Gamma and black levels too high.

Frame 122, original. Too Green. Gamma and black levels too high, brights clipped (some of them still are. See gal on the right). The "After" shot still needs work on the upper midtones.

All looks a little...mmm, grimy. Needs more denoising before hitting it with NeatVideo.
