Ripping audio from a trailer

[OzzieAlThor79]

So, I don't see a guide that really goes over this. Please correct me if I am wrong.

From the topic, it should obvious I would like to do an AMV to a movie trailer.

Are there best practices in getting the audio from a trailer put into MP3 format? I have the DVDs and such for my video footgae. I am not sure how to get the audio.

The trailer is one of the new "Star Trek" ones. I know I can download the Quicktime trailer for it. If I dig I can find it in MPEG format, no doubt.

Any advice on how I proceed?

Of course, after I post NOW I think I found what you will direct me to:

Am I right?

Pretty much, but why would you want to put it into MP3 format if you're then going to use it as source for an AMV?

Because I never saw this:

First things first:

YOU ONLY EVER EDIT VIDEOS USING UNCOMPRESSED WAV AUDIO

I have spent what free time I choose to use on AMVs just trying to get my footage to look good. Haven't spent alot of time till now going over the audio parts of the guides. This is the first time I am taking audio that isn't readily available to me. 3 videos in 5 years (2 of which I did without using the guides at all) ='s uber noob.

For the trailers from the Quicktime site, just demux them using MP4Box (or YAMB, if you prefer a GUI):

Code: Select all

mp4box -raw 2 "file.mov"

Then just decode the resulting .aac file to .wav using your preferred audio decoding app. I use dBPowerAMP most of the time, but faad would also work.



Or you could skip all that and load the MOV in an AviSynth script using FFmpegSource or DirectShowSource and then use VDub to save the audio to a .wav file. However, I don't know how that would work for 5.1-channel audio (which many trailers on the Quicktime site have; can't remember if any of the Star Trek trailers have 5.1 audio, though).

My workflow for authoring those 5.1-channel trailers to DVD is to use MP4Box to demux, faad to decode properly to a .wav with a WAVE_FORMAT_EXTENSIBLE header, and then give that to aften to encode my AC3 file. I prefer to retain all the channels when I author DVDs rather than downmixing the track to stereo.
