I need help to convert videos to Lagarith MP4!

[twindelphine]

I have been trying to convert several MP4 files into lagarith AVI format using the software SUPER Converter from eRightSoft, but I'm kind of stuck right now in several problems.

1. Where is the lagarith codec in Output Video Codec?
2. How can I properly choose the fps & bitrate for both video & audio?

Yes, I've searched online for related threads but the solutions' usually to download other software, or no conclusive answer at all. Hope someone would be able to help!

SUPER is not the software you should use.
Read <a href=http://www.a-m-v.org/guides/avtech31/>ErMaC & AbsoluteDestiny's Friendly AMV Guides Lovingly Overhauled Largely by Zarxrax</a>. As you will realize, you can easily do that with avisynth+virtualdub.

Yes, I've looked at that guide for a very long time. But it's very complicated, I didn't know how to convert.

My apologies for the double post, but I just want to mention that the videos are of H.264 codec.

Talk about title error! Sorry it's meant to be Lagarith AVI not MP4.

Anyways I'm just starting to know a little more about the VirtualDub/AviSynth. But for the code, what about MP4 sources? What code do I use to appropriately use the source videos?

[mirkosp]

Code: Select all

ffvideosource("your file.mp4")

then you load the script into virtualdub. The guide puts it as easy as it gets, really...

IFAIK, Super is based off ffmpeg/mencoder libraries which does not (yet) have lagarith support.
Only huffyuv and a few other lossless codecs specific to the ffmpeg library (wich are actually quite good, especially i like to use ffv1 for archives since its soo small) but if you want lagarith, you gotta go the virtualdub route

Get to know more about the virtualdub route. I'm using it at the moment to cut out certain scenes that I would want from the anime. Seems easier then I expected.

But I got one problem. When I attempt to sieve out the scenes, the input/output window in VirtualDub shows slight difference compared to the resultant AVI file. So I always get extra frames compared to what I actually see in VirtualDub. Is it because I used a not-so-powerful laptop to extract the scenes?

'yet' being, the Lagarith decoder's git repo hasn't had a commit since October, and the discussion on the ffmpeg mailing list seems to have died around the same time. There is no encoder, AFAIK. And it can only decode Lagarith files that were encoded in YV12. I've whipped out a couple builds of it (also of the ordered-chapters branch, which is friggin' sweet, but looks just as dead in the water).

The only one I have access to at the moment is this one (which, due to the fact I compiled it with GCC 3.4.5, MJPEG is supposedly broken - ffvhuff and ffv1 both work fine, though; I later did one using GCC 4.4.x so the MJPEG warning disappeared). Includes both Windows and OS X builds (the OS X build was done on Tiger using Apple's GCC variant from Xcode, so it's something like 4.0.x or 4.1.x)

The ffmpeg developers refuse to code a lagarith encoder when ffvhuff is capable of RGBA and FFV1 can technically* do RGBA with much higher compression and far less speed. MEncoder generally just uses ffmpeg and nobody in the mplayer crowd really cares about lagarith in the first place.


*technically in that it can encode RGB with an alpha channel however during the encoding process everything is converted to YV12 and then to the target colourspace, thereby killing any alpha channels. I forget if you can even have YUV+A in FFV1 but it would be interesting to see.
