Okay, this question has propably been asked too many times, I even searched it and couldn't find helpfull answers. So I'm going to ask it agian.

In the best, most understandable way possible, describe all the steps needed to convert .mp4 to one of those file types, please.

step 1: get avisynth 2.5.7 and install
step 2: get virtualdubmod
step 3: get ffmpegsource() and put the .dll file into c:\program files\avisynth2.5\plugins\
step 4: write an avisynth script that loads your .mp4 using ffmpegsource()
step 5: load that script (.avs file) into vdubmod
step 6: save as, selecting your codec of choice (which should be lossless [huffyuv or lagarith] if you plan to edit with this)

the first 2 steps can be substituted by getting the amvapp
the best solution is to buy the dvds so you don't have to convert .mp4 files

First, let me say that download footage will never be as good as footage you get from a DVD, even if you can get it to work in your program. Second, I'll show you how since you asked for specific directions, but you really should research this yourself or else you'll have trouble solving inevitable problems, and you won't be able to get the best out of you footage.

Anyway, Download the AMVapp. It will have all the programs you'll need.

After you've got it installed, Open up notepad and type Directshowsource("C:\youfolder\yourfile")

Save it with the extention avs

Find the avs file and open it up with virtualdubmod (It should've been installed with the AMVapp)

Set the compression settings how you like and save as AVI, don't compress it with Dvix\Xvid or anything like that

That was the horribly trimmed down explanation, read this (I know it looks intimidating at first) to learn throughly what you're actually doing and how to make best use of these programs.

It says:

Avisynth open failure:
script error: expected a , or )

Where did I mess up? Oh, and yeah, I didn't download footage for editing, I downloaded a video I wanted to put on my .mp3 player, and it doesn't support .mp4 but it supports .avi, so that's what I'm trying to work to do...

can you post your script?

Tox-sin · Post by **Tox-sin** » Mon Sep 08, 2008 11:26 pm

DirectShowSource (C:\Documents and Settings\(mynamehere)\My Documents\My Pictures\video.mp4)

That's the only thing in my script, nothing else, no extra spaces. Saved as .avs

DirectShowSource ("C:\Documents and Settings\(mynamehere)\My Documents\My Pictures\video.mp4")

try that.

just replace directshowsource() with ffmpegsource()
unless you have a directshow codec for decoding .mp4 files directshowsource won't work
