a/v sync troubles

Postby Kariudo » Fri Oct 06, 2006 4:24 pm

So I have the 4 disks of the region1 Full Metal Panic Fumoffu release...which I wish to consolidate to 1 or 2 disks.

I can do with just the episodes and english track.

So I rip the dvds and make my d2v files (using DGindex)
make my avs script
Code: Select all
Mpeg2source("F:\FMP\episode 1.d2v", cpu=4, ipp=true, idct=5)
Tcomb(mode=2,fthreshl=12, othreshl=19)
TFM(order=-1,mode=5,PP=7,field=-1,slow=2)
TIsophote()
Deen("a3d",1,2,5)
vmtoon(thinning=100, strength=75, ssw=2, ssh=2, xstren=75)
crop(8,0,-8,0)
lanczosresize(720,480)
tweak(sat=1.2)

anyone who's seen the R1 release knows how bad it looks...so I used this script to get rid of almost all the problems (the dot crawl and rainbowing is just too epic to completely erase...)

TFM preserves the 29.97 framerate...and I haven't done anything to the audio except transcode it to Wave-MP3 using BeSweet(for vdub...since it doesn't like avi+vbr mp3's) but whenever I try to encode my video (and add an audio stream) the audio isn't synced

I've also tried encoding with no filters and wave-mp3 audio (also with muxing the original ac3 audio and the video) but nothing works.

when I transcode, the audio comes out at 23:39 for Wave-mp3, 23:36 for mp3 (vbr) and the ac3 file gives me a length of 23:36...but my video is 23:06 (confirmed the framerate of 29.97 with vdubmod and bsplayer)

I'm transcoding the d2v file to avi atm to check the length when I don't use TFM (I'll post the results if the length differs)

any suggestions for how I would go about fixing this problem?
do I need to find a muxing program/do something else with the audio?
or am I just out of luck?

one of the officers [local anime club] was interested in the series after I brought the seventh episode in for everyone to see (the rugby club episode)

Ahhh ok, I see.

I'm not sure because I've never bothered to filter when I did that. Usually you can't see that stuff on a television monitor anyway, and I personally prefer detail over that smooth noise free but detail-less washed out look.

Of course, I've never seen Full Metal Panic, so I don't know if there's any fine details to kill or not.

I think I found a workaround...since vdub only hates mp3-vbr when encoding as avi...I thought I'd try encoding as mkv (using xvid)
and that worked

...still not sure why I was having so much trouble with the avi container...

and I'll get some screencaps showing how bad the footage is

dot crawl is most noticable on the [female] uniform bows and hair
rainbowing is most noticable on the [male] uniform sleeve stripes...but I didn't get any of those clips, so look at Kyoko's hairline, mouth, collar and shoulder

I gave up on rainbow removal (tried deblocking/derainbowing with mpeg2source, DFMDeRainbow and LUTDeRainbow...simulatneously before TFM...not much improvement)

this dot crawl was very noticeable on PC monitors, projectors and tv
just looking at it makes me cringe

You need a better TV.

But, yeah. The dot crawl is worse than I remember.

better than a Samsung 20' LCD?
also appeared on the Sanyo 20' CRT back home

it's just the footage...there's even dot crawl along the border of the video (look at the title screen on the left edge)

You can crop those out, you know. :P

I don't suppose DeDot helps?

Because AVI itself hates VBR-MP3. It requires some sort of hack to do it properly, and VDub doesn't support that hack (don't know if VDubMod does or not, although since it shows the warning too I'm assuming no). If it was CBR-MP3 it would have worked fine. Unless something else has come out that can do this as well, I think AVIMux is the only program that can actually do VBR-MP3 in AVI correctly - in other words, it's the only one that can hack it in properly.

MKV, on the other hand, includes support for VBR MP3 streams, so it doesn't require any hacks.

Nope, it doesn't - although it will do ABR-MP3.

I tried Dedot also...no effect before TFM, and yeah I could (and would) crop out the edges of the video to get rid of that dot crawl...I was just mentioning it as a testement to how poorly the R1 release was done.
yeah it could have been worse...but I don't want to think how bad it could be

I thought I tried cbr-mp3 audio...but looking back on it I probably wasn't.
I was transcoding the ac3 audio with the wav-mp3 option in BeSweet (this increased the length of the audio by 3 seconds)...probably should have used the mp3@128KBPS profile.

I was kidding about the TV thing (since obviously, I have no idea what kind of TV you have). But a higher-end TV with it's superior comb filter can sometimes reduce or eliminate the dot crawl. Of course, since the screens you posted are directly from the DVDs, the TVs comb filter never comes into play.

FMP: Fumoffu is notorious for the awful dot crawl. Seriously, i was going to make an animated gif from it for my avatar but the dots were all over the place on edges, masking would have been a nightmare. And it needed too much cleanup to look decent. Not to mention the bit that would have been gif'ed looked like it was made of about 25% dots constantly moving... :evil:

I have to mention that I believe that VBR-MP3 in AVI is the devil's work! I HATES VBR-MP3 in AVI. It always makes me redo my AVI-to-DVD transcodes from the sync issues. And I dislike having to do extra steps... :|

Have you seen the R1 OP for This Ugly Yet Beautiful World (aka, KonoMimi)? Oh, the humanity! And they didn't fix it for the second disc (and I doubt volume 3 will be any better, either). At least the R1 OP for Scrapped Princess got better (and for some episodes, especially the later ones, didn't have problems).

No I haven't seen that, but I have seen Scrapped Princess...and I didn't notice any problems with the R1 OP (then again...I'm not trying to edit that footage)

and the TV thing...I'm kinda Internet sarcasm inept
I have a bumper sticker on my forehead that reads, "Not compatible with internet sarcasm"

tried using the mp3@128kbps profile in BeSweet, but I still get that warning in vdub (...rewrite header...may introduce 3283 ms of skew...only matters when saving to avi.) and I keep on ignoring it
(I'm using the BeSweet GUI btw)

It may just be in how BeSweet deals with it. Considering the fact that I don't use BeSweet for audio compression (just the 23.976-->24 conversion for editing), I don't really know. I only remember that it has/had problems encoding proper AC3 streams, but I never tried that myself.
