Add SelectEven() or SelectOdd() at the end of your script.

[thetoof]

Adding selecteven/odd won't change the playback speed... only the amount of frames displayed in 1 second(59.94-->29.97).

and radar, what you are describing isn't possible with mcbob(), as it only bobs the video to 60p, which has no influence on lenght nor playback speed. What is the codec of the encoded stream? If you did a lossless rendering pass in uncompressed YV12 or Lagarith, it's possible that your computer can't read it fast enough... Try changing the process priority of your media player to "high".

[radar]

hi thetoof
i tried changing the process priority of the player,didnt work.how can i find what codec i used???

my system is:

intel core 2 duo E6850
4 gigs of ram
nvidia geforce 8800 gts 512

[thetoof]

Well, what did you use to encode your file after processing it with mcbob?
Also, could you upload a small 5mb sample to see if we can reproduce your issue?

[radar]

im using dvd rb and cce 270.
i will upload a clip.

what upload host should i use.thanks

[Didée]

No need to upload anything. CCE expects input that is DVD compliant. After bobbing, you have 50fps (PAL) or 59.94fps (NTSC), which is NOT compliant with DVD specs (only 23.976 / 25 / 29.97 fps are allowed). CCE silently assumes a compliant framerate, which is why the video then is running at half speed.

In this case you either have to use SelectEven() after MCBob, or you could just use a simple same-rate deinterlacer instead.

hi Didée
ok i will try SelectEven()


this is the clip:http://rapidshare.com/files/119202564/VTS_01_1.VOB

i tried SelectEven() and it corrected the slow vid.thank you very much Didée.
can i now sharpen the image.this is the clip after the mcbob.

Off topic. Look here.

[radar]

can i incorperate the sharpening in with mcbob script.
how would you write the script

[thetoof]

whateversource("yourfile")
mcbob()
any other filter you want() #like limitedsharpenfaster()

[radar]

ok i got this script,looks good but slow.
dose the script look ok.

radar,

If you are encoding for DVD, why are you deinterlacing?

Cheers,
David.

[radar]

its an old fight tape and it has interlacing.this gets gid of it.
im not sure if thats what you are asking.

[2Bdecided]

I assumed the source was interlaced, because you are using mcbob - not much point using it otherwise!

However, you can encode interlaced content onto DVD just fine - if you deinterlace it, you will remove half the temporal resolution, creating a stuttery look, like the "fake-film" effect used on some TV shows.

If that's what you want, fine. However, if you just want to make a good DVD of an interlaced source, you are wasting your time deinterlacing.

Cheers,
David.

[radar]

how can i make a good dvd copy with out deinterlacing.could you explain it to me ,thanks

[Revgen]

The only way you can make a DVD without deinterlacing is to make it 29.97fps or 23.976fps. DVD's don't support any framerate over 29.97.

[radar]

hi Revgen
how would you do that?

[2Bdecided]

radar,

If you want to do certain processing of your footage (e.g. denoising, sharpening, etc) then you do need to deinterlace, but you need to keep that at double rate, and then re-interlace at the end.

You can use this line of code to reinterlace double rate footage:

separatefields().selectevery(4,0,3).weave()

If it doesn't work, your field order is set incorrectly. In your script, you don't have an AVISOURCE statement, and you don't set your field order at all - maybe you're using it with someone that inserts these automatically, or maybe you cut them out of the part you pasted. Anyway, your previous script would change to this:

loadplugin("C:\Program Files\AviSynth 2.5\mcbob\RepairSSE2.dll")
loadplugin("C:\Program Files\AviSynth 2.5\mcbob\mvtools.dll")
loadplugin("C:\Program Files\AviSynth 2.5\mcbob\RemoveGrainSSE2.dll")
loadplugin("C:\Program Files\AviSynth 2.5\mcbob\EEDI2.dll")
loadplugin("C:\Program Files\AviSynth 2.5\mcbob\mt_masktools-25.dll")
import("C:\Program Files\AviSynth 2.5\mcbob\MCBob_v03c.avsi")
MCBob()

loadplugin("C:\Program Files\AviSynth 2.5\seesaw\degrainmedian.dll")
import("C:\Program Files\AviSynth 2.5\seesaw\SeeSaw.avsi")
backward_vec2 = last.MVAnalyse(isb = true, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec2 = last.MVAnalyse(isb = false, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
a=last.MVDegrain1(backward_vec2,forward_vec2,thSAD=400,idx=1)

b = a.DeGrainMedian(mode=1)
SeeSaw(a,b, NRlimit=5, NRlimit2=6,Sstr=1.5, Slimit=9, Spower=9, Szp=16)

separatefields().selectevery(4,0,3).weave()

Hope this helps.

Looking at your clip, it looks pretty good as it is - maybe I'm not so critical after all!

Cheers,
David.

i changed my script with yours and ran it in dvd rb with cce.the clip played alright,but it seems to be interlaced.the script that i posted deinterlaced the clip.

[2Bdecided]

If you really want to deinterlace, you do that. It's pointless for DVD, but don't let me stop you. I was just showing you how to process interlaced content through progressive-only filters, and get back to interlaced at the end. If that's not what you want, don't worry.

Cheers,
David.
