M2V With Both Prog+Inter Footage, Credits Don't Look Like The Original

[Master Yoda]

I have re-encoded ergo proxy(ntsc) which the original m2v is 23.976 progressive except when the credits roll it switch's to 29.97 interlaced, the encode went well except i have noticed that the credits don't look as clean or as smooth as the original does .

The AVS script has this in it

LoadPlugin("F:\DVD Ripping Apps\DoItFast4U\new.avs\decomb.dll")
Telecide(Guide=1,Post=False)
Decimate(Cycle=5)

Any ideas ?? I'm not too bothered about this as its only the credits but i would like to know why this happened and if there's any way i can encode without this happening and keeping the credits looking the same as the original

Hi-

You turned off the default deinterlacing (Post=False), and therefore, since the credits are interlaced and since they're not getting deinterlaced, you're getting jerky playing interlaced credits.

When I have that kind, I split up the .avs into 2 parts (the Trim command); the IVTC'd movie (encoded for progressive 23.976fps with pulldown) and the interlaced credits (encoded as interlaced 29.97fps) and join them when authoring in Muxman. That's the only way you'll keep them the same as the original.

Or try Decomb using Decimate(Mode=3) with the Telecide Post processing still on. You may or may not like the results, but it'll be much better than what you have now. Read the Decomb Reference Manual for more information.

mmmmm I could try that i guess although i use scenarist and import the script scenaid gives. When you say split into two parts do you mean 2 separate avs scripts? although for ergo proxy i would need 8 scripts

Hi-

Yes, one D2V and 2 scripts. I can't remember Ergo Proxy specifically, but I have made a bunch of scripts for anime before when they're all in a single PGC.

Do you have to use Scenarist? Don't or can't you use the original menus, instead of authoring them all over again?.

Anyway, for a script for all the the episodes together, you might try:

Telecide(Guide=1)
Decimate(Mode=3)

It's not perfect, but will handle the telecined stuff the regular way and blend decimate the credits. They'll still play a bit jerky but more smoothly than what you have now, and will no longer be interlaced.

Ergo proxy is one m2v for the whole 4 episodes rather than a single m2v for each episode like adv titles are.

The original menus will be used as i use dif4u, scenaid, batchupdateifo, i asked my question here rather than the dif4u forum as it was a question regarding mpeg2 encoding.

I'll give both ways a bash, more than one avs and the script you suggested.

OK, but one thing to keep in mind when joining a bunch of M2Vs at authoring time; unless you have a few black frames at the end of one and the beginning of the next, you should encode with Closed GOPs. If not you'll get these colored blocky artifacts for couple of frames at the joins.

When it's just black on white credits after a single episode, it's easy to trim off the 2 .avs's so that there are a few black frames at the end of one and the beginning of the other, and I can use my usual Open GOPs.

OK thanks for the heads up.
