hi, a side (or maybe off topic) question about 1 of the converting method mentioned on the 1st thread of this post.

Brief GDSMux primer:
1) rightclick the input area and hit "add source", find your .wmv and hit OK
2) rightclick the audio stream, choose "encode" and pick "PCM"
3) click the output button and select where to save the mkv
4) hit start
5) wait.
This will give you a VFR MKV with uncompressed PCM (WAV) audio.
i accidently found a raw wmv container video inside my comp that has:
wmv3 video - vfr
wma2/divx audio - vbr

problem is, the video worked fine through gsdmux. but when i tried to encode the audio stream to pcm i get a reply of "unable to bring out the encoder to the graph: invalid media type specified".... and that pick is the only exception that does that error.

am i missing a piece of encoder or something . i have the latest build of ffdshow @ 14feb09 + latest matroska splitter 1.9.42.1
edit: the vid plays fine by itself, audio + video. just the problem with gdsmux not recognising the audio codec

Find a decoder for it then. If you can load it into avs you can dump it to PCM in vdub or whatever. You could also try using Windows Media Encoder from M$, it has a thing to dumb audio streams, although it will still be in the WMA container iirc. Open with audacity to dump to PCM then.

Are there any groups releasing vfr episodes? I'd like to check the quality and decide if it is really necessary.

Check out a Rosario to Vampire Capu2 release. These are 23.976 fps episode, 29.970 fps ED.

That's too straight.
I thought, in vfr videos, fps changes every few seconds/minutes.

Very few groups will use VFR that alternates every few frames like that, because the episodes are animated at 23.976fps, and it's generally a good idea to encode at what the animated framerate is. The OP/ED is often 23.976 with 29.970fps credits overlayed on it, so some groups (see Kristen's comment above) CBF messing with it and leave the background at a telecined 29.970 rate that keeps it kind of jerky but makes the credits appear smoother/cleaner. It's up to the encoder really, either how clever/lazy they are, or how retarded, depending on what's going on.

if you want something that switches all the time, try white album
(eclipse's releases at least are vfr except the 2-3 first episodes, dunno about anyone else)

the first episode of gg's goku sayonara zetsubou sensei also switches to 30fps for random pans in random places but is otherwise 24fps

It can be relevant, yes. You can compare Eclipse releases of White Album episodes 2+. The MKV is true VFR, the AVI is CFR.

Thank you all of you, i have all of Eclipse's White Album releases. 1st episode has a 30fps opening, others have 24. Is this Eclipse's choice or was the show like this?

For episode 1, I only had a 29.970 raw to work with, therefore the release was 29,97fps too.

For eps 2+ I had the appropriate transport streams available (with one single exception, but there the raw was vfr too), so these are VFR. Besides, unlike most other shows, White Album is jumping around with framerates wildly _within_ the episodes too. Which is why I sometimes have 29.970 CFR AVIs and sometimes 23.976 CFR AVIs (depending on what's prevalent)

Really annoying stuff.

Spline36Resize(704,400) #or whatever resizer you like
Code:
FFVideoSource("anikuri15.mkv",timecodes="anikuri15_timecodes.txt") 
Spline36Resize(704,400) #or whatever resizer you like
The latter one keeps the vfr, and you need to mux in the timecodes that FFVideoSource generates to the timecodes parameter (in this case "anikuri15_timecodes.txt") with mkvmerge. The former one converts the video to a CFR of 23.976. You don't need to do anything with timecodes then, but you can get weird motion if there were any 30fps scenes.
i just wanted to thank you, you and thefluff solved all of my vfr woes

i failed many times while encoding a TS to VFR mkv/mp4
most of the time the subs or out of sync and audio too...

VFR from a TS or DVD source is a bit annoying. You need to either mark the 30fps sections manually using something like YATTA (or, god forbid, a handmade .avs), or use tdecimate's automatic 2-pass VFR mode.

One of these days I'll get around to updating the OP, it's only three years out of date or so...

I'm doing this
Code:
TDecimate(mode=4, hybrid=2,output="sometext.txt") #In First Pass
TDecimate(mode=5, hybrid=2,input="sometext.txt",mkvout="sometextv2.txt") #In Second Pass
to cut audio i'm using ur perl script...(don't know how to use YATTA )
still have no idea about VFR
Ah even adding AFX Logo to VFR encodes is bit annoying

that would be great idea TheFluff if you update the first page about vfr from a ts or dvd source for others to know how to properly vfr and not relying too much with automated 2pass vfr by tdecimate. i havent done any vfr on yatta because theres not much guide about it. only ivtc, but im glad ive known this program cos im able to ivtci properly my own dvdrips. i hope ill know how to setup vfr with yatta in the future.

but anyway, i think i still have this link http://forum.doom9.org/showthread.php?t=64314, a thread made by gizmotech of anime-legion. Its kinda old thread but its relevant to vfr you guys talking about (vfr on dvds). he made a guide how to identify and mark 24/30fps on dvd and encoding them vfr sucessfully. thats the one im using when encoding vfr with slightly different setup. idk whats its up and down since i havent done much vfr encoding and didnt bother if my vfr were fully right since no problems so far on those old vfr encodes of mine.

Simply mark 29.97fps sections as 'NoDecimate', so they wont get decimated and - guess what - remain 29.97fps. Yatta saves the timecodes file along with the override files.

The "o" key is your friend. Just remember when you mark it to do it in cycle 5 patterns with the decimation.

Moved this post over from the thread "VFR encoding, x264, and you" since the issue became more generally vfr over time.

Hi, my file switches between 24 and 30fps all the time.

Spoiler for timecodes:

When I use x264 with --tcfile-in and then don't mux the timecodes again in mkvmerge, only coreavc and ffdshow (beta 7) with h264 decoder ffmpeg-mt (and decoder threads:2 on single cores) play the file correctly. Ffdshow with libavcodec has audio- and softsub sync issues.
Ffdshow with libavcodec does work without sync issues when I mux the timecodes to the video track in mkvmerge but such a file seems to always jerk a little during 30fps pans when played with coreavc and a little less often when played with either ffdshow decoders.
Then I noticed it's the same for a hardsubbed mp4 I made with tc2mp4Mod.exe (which takes raw .h264 or cfr mp4 and timecodes as input). Coreravc and ffmpeg-mt work, libavcodec has a/v sync issues.

Any ideas what's the deal here and how best to handle it?

edit again: Even further experimentation shows it's also connected to the 2p tivtc vfr mode. Files created from tdecimate mode 3 all do work without muxing timecodes regardless of decoder. I even encoded one with the old timecodes created from the 2p modes 4 and 5. The only difference I see is the framerate of the lossless produced by tdecimate. Mode 4+5 generated a file that reported 25.8124fps and the timebase generation in x264 was 1/1000000000 whereas the mode 3 generated file reported 30fps and the timebase was 1001/360000.

When i see the 17.982018 fps segments, i would say don't use the Automation at all ...

So i have a Question to.:

I some how taught myself to use YATTA. Especially to cut, inverstelecine and bob transportstreams with it. One thing i still miss is how to locate scene changes and use patern guidance the right way wiht the "yatta_7-130-beta3" version that i have. The guide is some how to old. It is no big trouble for a normal .ts to do some patern and decitmaing change for the few cuts and to be carefull for the usual pattern changes at op, ed and eyecatcher. But i still have some vfr OADs lieing around that i would like to encode vfr. And this would be a hough workload without some help of the automation ...

Could some one point me in the direction of a guide or write a explanation?
