Please help me to learn about deinterlacing

[saint-francis]

I have managed to get by for several years now without really understanding how to dinterlace. I have relied on MeGUI for all of that. Well, now I'm dealing with BD material and I can't get MeGUI's script creator to open any of it so I need to do it the old fashioned way. And this is something I really should know about anyway. I recently got an animated TV series which is interlaced and also one other TV show that is interlaced. I have read all of the guides on the main site and I think I have an understanding of what interlacing and telecine are but I'm just not sure what to do about it. There are so many tools for the job. I don't really know which to use and how. So could someone/some people walk me through this and help put me on the right path to figuring it all out?

Here are some samples.

This is the first one. It's the Show I previously mentioned.

Here is the script I tossed together to deal with it:

LoadCplugin ("C:\Program Files (x86)\megui\tools\yadif\yadif.dll")
setMTmode (3,0)
Directshowsource ("F:\GEORGE_CARLIN\gc.grf", audio=false)
setMTmode (2,0)
Yadif (mode =0, order=0)
spline36resize (1280,720)
MCTemporalDenoise(settings="medium")


How does this look? I chose mode=0 for yadif because AVSP told me it was bottom field first. I don't know if it really is. I don't know how to tell. Could someone help me here?

Here is a sample of the animated series.

I haven't tried that one yet. As I understand it animation is often messed up in all kinds of ways. So I figured I'd use animeIVTC but I don't understand how to determine what mode to use. Again this is because I don't quite understand how to determine things like field order and so on.
Please, any help would be much appreciated.

Please post original material, not MKV files.

Please post original material, not MKV files.

Can you suggest a good way for me to cut segments of a BD .m2ts file that are small enough to upload and download?
And the .mkv's I uploaded are taken from an other .mkv made by eac3to (which is what I almost always work with whan dealing with HD disks).

You can use DGSplit in segment mode to make splits of your legitimately obtained M2TS material. If you have the DG*IndexNV tools, you can set a project range and then hit F1 to make a cut of the M2TS stream corresponding to the project.

Here is a section taken from the animation with DGSplit . Great tool BTW. I didn't know about it. And since I don't have an NVidia graphics card I don't have DGNV tools. Pity, I know but I sunk a bunch of cash recently into my ATI video card and (stupidly) a full cover water block for it.

A replacement for sample 1 is uploading now.

It's already ruined, as it is 3:2 telecine that has been blend deinterlaced. There's nothing you can do with it.

Just out of curiosity, what is the title and region of the DVD. I'd like to see if this crappy product is already known about.

Here's some help with your question about how to analyze source. See questions 1 and 2:

Damn! Maybe I'll return it and wait for them to re-author it. I'm sure the DVD is no better so there isn't much point in getting them instead.

Here is the new sample of test 1:

Your test 1 clip is pure interlaced video. Use the deinterlacer of your choice if you require a progressive encode.

It's TFF.

...if you require a progressive encode...Not sure saint-francis what your intent is with the video but if you are converting with x264 you CAN leave it interlaced with the --tff or --bff options.

I recorded a TV program a while back that I was not able to de-interlace satisfactorily, so I just left it the way it was. At least it looked as good as the original...!

The video is salvageable by deblending with srestore, although some small artifacts and aliasing may remain. There is more discussion about the issue here: http://forum.doom9.org/showthread.php?t=145623 (it's a different thread than the one neuron2 linked to).
