Second Pass/DVD "lines"

[archon231]

First question was in another forum, but i think this is a better place for it ^_^.

"I am having a problem making the second pass, i have done this before with one short video (~1.40) and now i'm trying it with a longer one (~25 mins) and i got the first pass and the stats file to work fine, but it freezes when i try to start the second pass. This happens both ways, doing them all at once and seperate.

Any help, tutorial, FAQ, whatever would be great thanx."

Second is, when i encode from dvd (DVD>Smart Ripper>DVD2AVI>convert(VFP...whatever)>Nan/Vdub) i get these "lines" on the video when the motion is mid to high, its not regular pixelation, its different, no matter what bitrate i use (except REALLY low, cause its too crapy to see anyway) i can see them, and i dont think i've seen these on other ppls rips, i must be missing something, but an answer to that question would be good too ^_^.

-Thanx

Hi-

I answered the first question at the other place you posted by pointing you to the guides. As for the second question, those are interlacing lines, and will be taken care of by either Force Filming in DVD2AVI or IVTC later on. I believe the Guides also discuss the issue (but I'm assuming this is an NTSC DVD-PAL material will be handled differently).

Also-be careful about double posting-I'll let it go this time because you sneakily added another question.:) But maybe you should have a look at the Forum Rules (http://forum.doom9.org/forum-rules.htm).

thank you and sorry ^_^

But i did not see anything i was doing wrong in the tutorial (which i failed to mention, i used to learn how to do it (VERY GOOD BTW ^_^)in the first place) Also there was nothing about it in the troubleshooting.

As i said before i HAVE SUCCESFULLY done a few 2 pass videos and they worked fine, but this one seems not to want to. It is a US dvd, which i think is NTSC... correct me if i'm wrong (/me is still a lil new :P) so if that helps...

Well anyway, thanx for the help with the "lines", testing it now ^_^.

*BUMP*

OK... this has been here QUITE some time now, and i REALLY need help!!! The first answer helped, but i still need help with the second pass thing :( so PLEASE ANYTHING, ANY HELP would be SWEEEET. Thanx.

Hi-

Persistent, eh? IVTC should take care of it. Have you tried? What's the source, DVD? And what is it? I assume it's some kind of anime. They can almost all be IVTC'd. Are you using GKnot? Have you tried to make the .d2v with no Force Film, and then applying IVTC when setting up the .avs? Show me the .avs (and cut out all lines beginning with "#"). Maybe read and memorize The DVD2AVI-IVTC Tutorial (http://www.doom9.org/ivtc-tut.htm).

well... thanx for the reply but, what is this IVTC?.. :\ sry, like i said i am new, and only know the easy stuff.

btw, it is an anime dvd.

So... i guess that mean i got some reading to do T_T ghah.... well i'll post once i finish the reading ^_^ lol, /me is VERY lazy today.

thanx ^_^

Hi-

IVTC=Inverse Telecine, the reversing of the telecine process. That is, you're returning the 29.97fps DVD to the material's original 23.976fps (well..originally it was 24fps). If the material was originally created at 24fps, but for one reason or another Force Film in DVD2AVI doesn't work, then it must be IVTC'd. It's all explained in the link. If you're still using the VFAPI method (and you drive a Model T car also?), then there are links at the bottom to Doom9's guides about using TMPEGEnc to perform the IVTC.

Yay reading T_T, well as long as that fixes it so i CAN do the second pass, since everything else NORMALLY works great, small files/good qual.

Hi-

Are you still having trouble running the second pass? I might recommend that you switch to using Gordian Knot and AviSynth. It'll mean more reading of guides, but one benefit will be faster encoding times. And GKnot automates the procedure, so there are fewer ways for you to screw up.:)

And your buddies at #anime-dominion can't help?

[archon231]

No they cant help, we're a REALLY small chan T_T starting out, and i'm the only one CLOSE to haveing decent knowlege about sbc. I can do regular, old school stuff, but making smaller sizes ain't my bag.. yet ^_^

[archon231]

Ok, well i got around to the tutorials and tried everything out.

1st: I changed it to IVTC using the tutorials and did everything as it told me (using auto, i dont get the manual way) and still second pass, Nandub freezes.

2nd: Is this really the problem? I understand maybe it wouldn't work, but y would it cause it to crash.

3rd: I really need help fast T_T i'll try Gordian Knot soon, but i like Nandub's SBC stuff, so if i could get some help, i know ur busy buy, something other than referals to tutorials that'd be great :)

Again thanx for all the help, but i need even more ^_^ /me is still too new, but i wanna learn!! ^_^

Hi-

I can help you, but why don't we take it private-send me a PM. But I'll do it only if you're willing to use GKnot and an .avs. Send me your .avs with the lines beginning with "#" taken out. I recommend you do that anyway so you can make sense of the thing. Also, give me the name of the anime-maybe I've ripped it before.

However, the freezing problem is something else I would guess. Are you overheating, by chance? There's very little that will stress a computer the way video encoding does. Maybe run Prime95 for a few hours to insure that you're completely stable. Are you running Motherboard Monitor so you can keep an eye on the temps?
