Hello all,
I am relatively new towards encoding anime (particularly Japanese cartoons/animations). I've poked my head through quite a few past threads related to anime, and I wasn't able to find an answer to what I am looking for (please point me though if there's something that I've missed!)
This is to do with frame rates, (possible) inverse telecining and decimating. The sticky tutorial in the DVD2AVI thread was very useful on this matter! And I frequently find myself re-readings bits whenever I wanted to make sure of things. However as the guide suggests, the situation for anime is quite challenging, and indeed I find it so with the current anime that I'm wishing to encode.
Particularly, I am encoding an anime title named Black Jack. It's in a movie format as opposed to series, and I doubt that it's a popular one at all. This is a PAL version with 25fps, released by 'Madman'.
There seem to be a lot of combing / interlacing effects, although they are certainly not on every frames. On a rough count, sometimes there could be 4/5 interlaced frames, other times I get as many as 8 if not more consequtive interlaced frames. The pattern seem irregular, not to mention a lot of repeated frames as well (exact replicas, often *slightly* shifted from the position of the last duplicate frame, just so slightly but enough to be noticed.)
I am using DivX5 for the job, and I've encoded 3 clips from the movie for testing purposes. They are basic GKnot prepared scripts with following modifications:
clip 1:
template clip for control purposes.
Interlaced frames appear intermittantly to frequently.
clip 2:
de-interlace enabled in the options in GKnot.
Ghosting and a little interlaced artifacts were visible.
clip 3:
loaded decomb filter, inserted telecide(post=false).
clip 4:
loaded decomb filter, and inserted telecide(chroma=true) together with decimate(mode=2). Has the least ghosting, plus (questionably) the least amount of interlacing effects remaining.
On a still scene, the picture even seemed to rock like wild, on all 4 clips. I've checked and the VOBs on the hdd behaved the same when played (much like clip no. 1, including the interlacing effects).
I'm aware that there are many types of settings that can tweaked for a better result. Can someone point out if I have left out certain helpful settings or parameters that can help in anime encoding in general? And if anybody have had experience encoding this anime title, inputs will be very much appreciated :)
Thanks in advance.
