That's why I'm asking for help here.

Easiest way out would probably be to use the x264 CL or meGUI to encode to raw .264 or mp4 and mux it with MKVMerge to .mkv

At 2200 bitrate, you get about 700 mb for 45 mins. If you want a smaller filesize, reduce the bitrate.

Does that happen when I save a h264 video stream in mkv from MeGui too?

No. MeGUI is just a GUI for CLI apps, doesn't use VfW at all.

<rant>That's why people should at least mess with the CLI and not depend on any silly GUIs to find out what the heck is actually going on.</rant>

I encountered a problem when using the clis.
Using directshowsource or dss2 makes the dos-window pop up showing the commandline and doing nothing (but blocking the files for a few seconds until returning to the prompt) but they all do work when using MeGui. The same batchfiles and videos work as expected with the cli when using ffvideosource or avisource to load the videos.
It's the same for x264.exe and xvid_encraw.exe, the latter also shows "trying to retrieve width bla" and "avisynth detected" before stopping. The directshowfilters are ffdshow and xvid. A mencoder ffvhuff commandline doesn't care how the videos are opened in avisynth.

then you haven't looked hard enough

(hint: in most material you want at least SOME kind of dithering/grain to make it not block like shit in flat areas, particularly dark ones, and dup really screws with that, as well as with small mouth movements and stuff like that. the gains are insignificant anyway so just don't bother)

x264 is efficient enough that it provides very little compression benefit nowadays. And I've also seen problems occur with settings of even 0.3 too, so it's Just Not Worth It.

Uhm... Dup won't remove that grain (I know, you probably didn't mean it since you very well know that, just used bad phrasing I guess), it'll only might make it appear more stable on a still scene. I personally much rather like to see "static" grain rather than some shit that jumps around like crazy even when nothing happens in a scene. I think that for an effect like this is worth using it...

@checkers
I'd be well interested in knowing what that was... I encountered problems with using 0.3 just a single time, and that was a pan on a static scene where it moved just by one single line (stupid mahou shoujo craziness). Using 0.2 helped, but then 0.2 is so low it barely affected the other, non-problematic areas.

IMO dfttest-like denoising + addgrain(constant=true) is better than dup for that.

Hi again.

I'm having some weird trouble with Evangelion Rebuild 1.0 (You're Not Alone).

The thing is, the video is reported by DGIndex as Film 99.50%, Frame structure Frame.

If I use Force Film, paning scenes and the video overall stays as it should, no interlacing, combing nor dups at most scenes. BUT...

In certain scenechanges, I get some nice combing, I was not expecting it:



So, I wonder if I should just take note of all these scene changes, and freezeframe every combed frame? Or is there a better solution? I don't think this source needs IVTC, as Forced Film does what it should, except for this little problem.

This is my script, pretty simple:
Code:
crop(4,8,-4,-6).spline36resize(720,480)

if it's the R2J DVD, for some reason it isn't mastered properly. you are correct that it is indeed progressive and it really should be 100% FILM, but for some bizarre reason there seem to be missing fields at some scenechanges (they probably cut it improperly). this is why you usually don't use force film for anything less than 100% FILM, or if you do you really need to QC it carefully because you really can't trust studios to do it right.

tl;dr you need to either freezeframe every single affected scenechange (lots of effort), use YATTA (or use fieldhint() directly) to manually force a n or p match at the affected scenechanges (same effort as freezeframing pretty much) or just set dgindex to honor pulldown flags and do ivtc as usual (a lot less effort for a probably equivalent result).

I see, so it is badly mastered. So, doing IVTC with AnimeIVTC would suffice? I really want to avoid YATTA for an almost 2 hours movie .

animeivtc is overkill in that case, just do tfm().tdecimate(mode=1)

All right, thank you TheFluff. I'll use that, I hope it comes out without terrible combings.

EDIT: Worked like a charm

What better way to learn than to ask. So here goes.

What is AR encoding?
If anyone has a guide or a process for this can you share, please.

Thought here would be the best place to ask, if not, please point me to the right place.

AR usually stands for Aspect Ratio, beyond that I have no clue what it might mean

Maybe how the AR gets encoded in the video stream?

ie x264 --sar or something like that.

Video: MPEG4 Video (H264) 704x480 (4:3) 23.98fps [Video]
Video Size: 704 x 528

I'm talking about how it's encoded at a specific resolution, but then the aspect ratio ends up switching the resolution. Just like above. It says 704x480 but it plays at a 704x528 resolution.

Does that make sense? If so, is there an encoding guide somewhere?
