AutoGK and hybrid source

[gatormac]

I am trying to encode the Band of Brothers series and have come across this problem:

DVD2AVI in Robot4Rip recognizes this as hybrid material and does not force film. There is some interlaced content in the starting title and the entire credits are interlaced, but the movie itself is telecined. I resolved this by simply IVTC'ing in Gknot. Everything looks good except the credits, which of course look awful. Then I tried it with AutoGK 1.17, it once again recognized it as a hybrid source. The resulting video looks good, but once again the credits remain interlaced (and of course IVTCing any kind of interlace content doesn't look good). I thought AutoGK could restore hybrid sources....or does it just correct the highest percentage of a hybrid source? I would like to have the movie AND the credits play correctly. Here is the log file:

AutoGK did its best in this case. You can manually try adjusting threshold for decimate() but that's it. I'm sure that credits in AutoGK rip looked better that if you just IVTC, but its not perfect indeed as there is no way 30fps material will look the same in 24fps...
And btw, credits looks just progressive, not interlaced.


P.S. get PAL version of it and you won't have any problems :)

[gatormac]

So you're saying that its a progressive source thats been IVTC'd? I guess that makes sense since the playback is so choppy.....I suppose I could simply encode that section seperate and then append.

Thanks for your help!

You can't actually - since framerate will be different, so you'll be unable to join those junks into one AVI.

[gatormac]

Hmmmm.....I guess for now I will just encode the movie. Thanks again for preventing me from wasting my time :D

[len0x]

now you see what this Hybrid problem is all about :)
