Weird Pulldowns and DeInterlacing

[ez-dvd]

ok, so I have Space 1999 on ntsc dvd. The show was originally broadcast in .uk, so what I want to do is convert it back to PAL @ 25fps for the xvids.



ConvertToYUY2
Bob()
ConvertFPS(50)
SeparateFields.SelectEvery(2,0)
Weave

does a wonderful job of converting back to 25 FPS and removing the ntsc interlace artifacys, but I'm having issues with "ghosting" in some frames, and heavy black horizontal bars on others that appear to be interlace lines.

Help? ANY suggestions will be warmly welcomed

is the original mpeg2 file 23.97 fps film rate with pulldown added to it to make it 29.97? or is it just straight 29.97 interlaced?

Hi-

If it was originally interlaced PAL, then you're screwed, as there's no way to remove the blending. But lets assume that it's originally 25fps progressive, and is a bad PAL to NTSC conversion. Put on a Smart Bobber alone. Use KernelBob(Order=1) or TDeint (Order=1,Mode=1) to check. I suspect that it's a PAL to NTSC conversion, and it started out blended. If you see blending in the fields, then that's the case. If so, then you have to unblend it to get the best result. The faster way is to use RePAL:

Assume(TFF)#change if BFF
KernelBob(Order=1)#faster#or use LeakKernelBob
#TDeint(Order=1,Mode=1)#Slower but better
RePAL().

That'll give you 24.975fps, and you can keep the audio unchanged. If you want 25fps, then add AssumeFPS(25) to the script and adjust the audio length in BeSweet (24975->25000).

The slower, but some say better way (not I, though) is to use Restore24:

AssumeTFF()
A=R24KernelBob(0)
B=TDeint(Order=1,Mode=1)
Restore24(A,B,1250,2997)

That'll give you 25fps, with no need to adjust the audio. However, if you've never used Restore24 before, there's a bit of a learning curve involved, and you might be better off sticking with RePAL.

If, when you put on the Smart Bobber originally, you don't see blending, then it has just been slowed down for NTSC, and you can IVTC it, and then add AssumeFPS(25) to the script and adjust the audio. In some few cases, where you don't see blends, you can IVTC back to 24.975 with something like (Telecide(Order=1.Guide=3).Decimate(6). If this was a BBC documentary, then they always do those crappy PAL to NTSC conversions for the NTSC DVD, and RePAL does a good job on them, removing most, but not all, of the blending.

Test the final script you use in VDubMod before doing any actual encoding. You can find RePAL here:

excellent! i think that is going to work, I've collected the plugins and am looking at it now. My first impression is that this will "properly" convert it back to the original PAL framerate. Will post a screenie for you afterwards

*EDIT*

Or maybe not......
The script loads and previews fine in both v-dub and v-dubmod. However, after adding to job control, it crashes both as soon as i start the job. Any clues about this?

Hi-

Not really, as I don't use the Job Control often. I'd try this first; after setting up the jobs, close VDubMod, and then reopen it to run the jobs. If you have several jobs, it may still crash after one or more of them. I have found when using complex scripts, that after fooling with them, and reopening them in VDubMod, that it will sometimes either close, or give me an access violation for no apparent reason. Your problem is probably related, so set them up, close VDubMod, and then reopen it to run the jobs.

Another thing you might do is to try an earlier version of VDubMod. I use ver. 1.5.4.1.

Another thing you might try is to not use the Job Control at all. Just run them one at a time. There have been lots of reports of problems with the Job Control.

I saw you in fxpdupe.
