MCBob

[rec]

Hi, This is my first post - hope I'm in the right place.

I want to use MCBob, but I can't figure out how to apply it to a given clip. Could somebody gently take me through the steps?

I work daily with simple AVISynth scripts, but nothing as complex as MCBob.

Thanks!

[Adub]

save the script as extension ".avsi"

put it in your plugins folder. Then call like so:

MCBob()

OR

MCBob().SelectEven()

Thanks, got it working.

Next question: As the filter stands, it deinterlaces 60i to 30P. Is it possible to change it to go from 60i to 60P?

Also, can you use it with multi core processors?

MCBob()

Deinterlaces it to 60P.

As long as you have the latest versions of mvtools and MT avisynth, yes.

what is the speedup using mcbob on dualcore machines?
and what about 4core?

[rec]

I'm running mcbob on a quad core 6600 overclocked to 3.2ghz.
Unfortunately, only one core gets utilized. I'm using avisynth 2.5.7.0 and mvtools 1.8.4.2. Deinterlacing a 60i HDV picture @ 1440 x 1080 takes 2 seconds per frame. And looks great, btw.

Sure would like to use all four cores. If anybody has any ideas, please speak up!

Make sure to put threads=4 in the NNEDI() section of the script. Also make sure you have the latest MT and SetMT version of Avisynth. And lastly make sure you have the latest multi-threading enabled version of MVTools. Make sure that SetMT is above the source line too. For example:

SetMT(mode=2, threads=4)
Avisource("Mydrive:\Myfolder\mysourcevideo.avi")

If that doesn't work, then you'll just have to use trim() and process 4 separate segments of the video and assign each segment to one core via taskmanager. Make sure all 4 segments are encoded losslessly so you can encode them to xvid, H.264 or another codec later.

Are there any suggested parameters or modifications to mcbob that will improve speed, but not damage quality on a noisy (S-VHS) source?

Cheers,
David.

mcbob is amazing but I have some issues on horizontal lines: they shutter
If I put selecteven it is fine but I would like to keep all the 50 fps.
I am using mcbob() without further configuration is there an option that could work for me?

[foxyshadis]

Can you post an example of the video? MCBob should bob less than other bobbers (if that's the case, that's probably the best you can hope for), if it doesn't it could make for a good test case.

[g_aleph_r]

it's a little difficult for me to post a part of the file. Anyway the problem is mainly the watermark of the channel and the graphic of the show.
I solved (almost) using tdeint and mcbobbed stream as clip2, it doesn't like flash but it is not so ugly.

[some dude]

I don't know about getting rid of the watermark, but to keep your 50 fps without using selecteven you could try

complementparity
MCBob()

I'm not sure if this would fix your "shuttering" lines, but I'm not sure what you ment by that in the first place.

[badshah]

MCBob_v03u is giving me speed of 0.5fps on my c2d with 1gb ram. can anyone help me ?

[themostestultimategenius]

^ Try using MT AviSynth.

[Adub]

Just make sure you are using the most up to date versions of Masktools and MVtools, as they used to have problem when using MT in Avisynth.

Oh, and even if you do use MT, your fps still wont be stellar.

i'm trying to deinterlace an old anime ntsc r1 (usa) dvd.dgindex reports it as interlaced.here is a sample:
http://rapidshare.com/files/97003811...muxed.m2v.html
i'm trying different deinterlacer,am i right using mcbob like that

DGDecode_Mpeg2Source("H:\Kimagure Orange Road Movie 1\VTS_01_1.d2v",info=3)
colormatrix(hints=true,interlaced=true)
mcbob().selecteven.tdecimate(mode=1,hybrid=1)

to convert it to 24p?
should i use a different deinterlacer?

If you're interested in trying something other than mcbob you could look at this thread: http://forum.doom9.org/showthread.php?t=135688

Is there a way to use mcbob just in a section of the encode? Because I'm getting "Framerate doesn't match" error when using trim...

And another question... I know that mcbob doubles the framerate, but how can I get original framerate (29.97fps) back?

Maybe you're getting that error, because you need to discard half of the frames mcbob creates?

To get the original rate, use either selecteven() or selectevery(2,0) after mcbob.
