View Full Version : NTSC animation captured in DV, what sould I be looking out for?

I am about to do some cleanup and conversion to DVD and x264 of some analogue captures of animated content. Unfortunately, due to spaces constraints, HuffYUV was not an option and DV was used instead. Aside from whatever filtering I'll be using, is there anything in particular I should be adding to the filterchain due to the specific issues of DV compression of NTSC material?

Also, what kind of benefits (if any) would I get from using NNEDI-modded MCBob over TDeint+TMM+NNEDI as a helper clip for TFM?

This article may be a bit old, but it is still valid:

I used this for a lot of my anime cleanup. The suggestions it gives is really helpful. The final outcome is brilliant compared to the original. I thought the original was okay until I read the article in full.

Good luck. :)

Ah yes, I know that link :). I appreciate the help StifflerStealth, but as you say yourself, the article is old. Every single one of those filters have been superceded by much more efficient alternatives. Besides, most of the filterchain for these captures has already been decided, which is why I'm (currently) only asking about how to deal with artifacts related to DV compression of NTSC material. I do appreciate such a quick answer, so thanks :).

Occasional blocking and ringing is probably the only problem you'd notice with DV, like any codec. Aside from loss of texture you can't do anything about. mjpeg tends to have a little more ringing, DV tends to have a little more blocking. Find any frame with gradients and sharp edges and you should be able to configure filters for that. (Might want to use x264 with a low q and no bframes next time - same ludicrously high bitrates, less artifacts.)

What about ReInterpolate411, will that help in any way?

Only if you use a DV codec that outputs 411. Don't! Cedocia has the reinterpolation to 420 or 422 built in.

What about my second question? Is it worth it to use McBob as alternative clip for IVTCing?

No, it's not. Not at all. Do the single fields of a telecined source represent a continuous temporal flow? No, they don't.

Once more: MCBob is only suited for "true"-interlaced content.

Makes sense :o. Thanks for the reply :).
