Encode using mp4 as the input file?

[enchant1]

The only encoding I've done thus far is by using a .avi as the raw source image. I create a script using AVSEdit, specifying the .avi and a .ass files to create the final encoded mp4 video with subtitles.

Now I only have a .mp4 as a source video. Can I still use Megui to encode in the subtitles?

Thanks for any help.

There is a better editor called avsp, it's hard to guess what exactly you try to achieve so more details would be helpful.

I'm not sure what other details you need. I normally get a .avi video and a .ass file with subtitles. The final objective is a .mp4 video with subtitles. Using VirtualDub, I can extract a .wav file to use with Megui for encoding

But now I've got a .mp4. Along with other incompatibilities, VirtualDub doesn't recognize .mp4 files, so I can't extract the .wav file.

Don't really see the problem here. :confused: You should be able to use the following script and MeGUI (or any other GUIs using AviSynth) if you write this script:


video=FFVideoSource("video.mp4")
audio=FFAudioSource("video.mp4")
AudioDub(video, audio)
textsub("subtitle.ass")


Install FFmpegSource (https://forum.doom9.org/showthread.php?goto=newpost&t=127037) and VSFilter.dll (http://xvidvideo.ru/2009-10-22-10-49-14/doc_download/2972-standalonefilters-svn1557x86.html) beforehand.

From where do you have the AVI, MP4 would be a start and if you aren't aware of rule six it might as well be the end I'm afraid.

There may indeed not be a problem, and perhaps your script will work fine.

Can I use the single mp4 as my audio and video source?

One other side question...

I used to use Virtualdub to take a large .avi file and just save a couple minute segment of it for testing purposes. Is there a way I can do this with an mp4?

Yes. I mistyped it in my post. Corrected now.

Are you sure about those links? One is a forum post by someone complaining about a problem, and the other is a Russian website. That is, unless I have some sort of virus that's altering browser links.

The first link was supposed to link the thread, not that specific post. And yes, the link to that russian website is correct. It's a site of a doom9 forum member and is virus free.

Thanks. I wasn't suggesting that the site was infected. But a few months back, I got a virus that would take links on a page and change them to go to a different site.
