Working w/ heaving Interlaced source

[Hoagie]

I just started working with a new animation title that is very heavily interlaced. At times, using TMPGEnc manual IVTC, I can only find a single non-interlaced frame. The title is pretty old (early 80's), so it is all hand drawn.

I've tried various output settings in DVD2AVI. The resulting source is still very interlaced, no matter what settings I've used.

What is the best way to work with this video, with the final result being a DVD complient MPEG-2. I figure I am going to have to deinterlace no matter what this time (haven't with past titles, using manual IVTC) -- would it still be better to drop the framerate to 24fps, or should I just keep it at 29.97 for better results?

Many thanks for any help!

What title is this? If it's Gunbuster you can forget about it, it suffers from the GAiNAX twitch. GAiNAX is notorious for doing the most horrible Telecining ever in animated shows. If it's something else please let me know and I'll see what I can find out.

Also - don't bother doing manual IVTC in TMPGEnc. 99% of the time DeComb will give you just as good results and without all the hassle of manual IVTC. If Decomb can't give you a good looking stream then it's because the show has blended frames i.e. uses an older form of telecining that's really really nasty and almost impossible to fix.

I would just recommend encoding interlaced.

The title is "Orguss". It's an early 80's title by the same folks who did Macross (if you are unfamilier with it). U.S. Renditions put dubs of the first several volumes out before they went belly up, which are almost impossible to find now.

I'm working with the R2 DVDs (actually, they are R0 but still from Japan) that came out not too long ago. The quality on the TV is great, but man was I pissed when I pulled this thing up in TMGPEnc! :(

I've never had any luck with DeComb, even when working with very good titles (namely, Macross 7 -- very clean, very well done). I learned how to do manual IVTC over a year ago and I can do it almost as quickly as it would take me to type in "decomb" in a AVISynth script. Ok a little longer, but I just like manual IVTC; makes me feel like a big man. :D

Eh? I swear when I started doing all this I tried a straigt encode from interlaced source to an interlaced new and the result was noticable interlacing on playback. Maybe it was just in parts, or maybe I am just drinking too much Mountain Dew and it is starting to rot my brain.

So you suggest just load the video up as an interlaced source and encoding an interlaced result? I'll give it another try when I have the chance -- I'm not too concerned about space (it's going right back onto a DVD) so if it works, I'll be vrey happy.

I would suggest trying the newest version of DeComb again as there's a new decimate mode that works very well for Animaton.
And yea I'm familiar with Orguss but I have no idea about the quality of the telecine so I can't help you there. But try out the newest Decomb, and if you still have trouble ask Don for help by maybe just sending him an email - he can probably tell you if the clip is IVTC'able or not using any method.

Ah edit crossover!

Can you check out my edits above too, last half of the message? :)

My advice, if you don't want to deal with the IVTC (which sounds like the best option at this point):

Take DVD2AVI and have it output its .d2v file with plain, standard fields (not forced film, not swapped fields).

Open up said D2V file in TMPGEnc. Set your field options on the MPEG2 to Interlaced. Encode.

Or if you're using CCE, use MPEG2DEC to open the D2V file, feed the AVS script into CCE, and encode (just make sure the Progressive Frames option isn't checked in your Video settings).

That should give you a clean interlaced->interlaced transcode.

Thanks ErMaC,

Encoded the first episode and it looks alright on the computer. Haven't burnt it to a DVD yet, but I'm sure it will look fine! Guess the Dew is routing my brain, I don't remember being about to do that in the past (Interlaced->Interlaced)... perhaps the mixture of NTSC and FILM would have resulted in my failure at earlier attempts.
