How to convert MP4's with the new AMVapp 3.0 beta

[Zarxrax]

There are plenty of good documents people can google about why audio in avisynth is bad and there is no reason I should need to explain when people are just too lazy to look it up themselves.

I would be interested in seeing these documents, and I did not find them after a cursory google search.

Audio in avisynth doesn't always work (it sucks with certain things on PCM which are common on bluray) and even when it does it is lossy.

You might have noticed that the op isn't dealing with blu-rays nor PCM audio here.

The best way to get audio cut properly is using a perlscript like split_aud.pl (google it) which reads trim points from an avs file and after taking a framerate argument uses mkvmerge to cut and rejoin stuff. You can splice with mkvmerge directly if you need to join multiple segments.

mod16.org is down D:
that, and perl isn't something an editor is likely to have (much less know how to use/install).

You'd do well to realize that the majority of people asking for help here:
-Are scared of command line
-Probably don't have any computer programming experience
-Aren't involved with developing avisynth
-Want the simplest solution (taking the least amount of steps/work/knowledge)

I would like to consider the most difficult options, but the subject here is how is everybody editing MP4's in VirtualDubMod with sound? I have not yet moved onto ripping HD-DVDs and Blu-rays.

Most people don't use virtualdubmod anymore since it's outdated, and the simple virtualdub is much better.
Anyway, what you need to do is just opening the MP4 in avisynth like so:

Code: Select all

audiodub(ffvideosource("your file.mp4"),directshowsource("your file.mp4"))

Then load the avs file into virtualdub and you'll be able to use the audio menu to your needs.

ffaudiosource k go? Or just demux in YAMB and convert to mp3 seeing as these people obviously have no need for quality. No wonder AMV editors generally have no idea what they're dong. CLI is good for you.

Before you storm off in a rage, you do understand that you've given us absolutely no reason to believe what you have claimed, right?

If you can't provide proof, don't expect to be taken seriously.

As for editors not knowing what's going on behind the plugin calls they make to avisynth, you really shouldn't be so surprised. Just like I wouldn't be surprised if you couldn't make a decent amv or tell a 'good' amv from a 'bad' one, these are different communities with different interests and technical strengths.

Code: Select all

audiodub(ffvideosource("your file.mp4"),directshowsource("your file.mp4"))

Then load the avs file into virtualdub and you'll be able to use the audio menu to your needs.

Tried it. This did not work.

[Kariudo]

what error did you get?

[Daniel_BMS]

A very large error. The error said more than once that it can't find the audio and video.

[Mister Hatt]

AVS uses relative paths. If your path to the file is incorrect, it will error. Your script needs to be in the same directory for that to work.
