What's the fastest way of making an mp3 a video?

[Foofaraw]

Say I have an mp3, I would like to turn it into a video - pictures doesn't really matter(though i suppose a slideshow could be handy).

What's the quickest way of doing that?

A quick way would be to use mkvmerge, drop the mp3 in it, drop some video - disable its audio if it had one, and then click 'start muxing' - that is fast, but since the length of the mp3 is unknown its unlikely to find a video of the right size on the spot.

Avisynth:

a=Nicaudio("your.mp3")
b=blankclip(random parameters)
avdub(a,b)

NOTE: parameter & function names not accurate, purely a demonstration of concept ...

you should read the avisynth docs.

The easiest way would be to use an NLE (video editing app). iMovie on Mac OS, or Windows Movie Maker on Windows are well suited to this task.

Failing that, I'd do something like this (example with just a few photos, with 10 second duration each)


a=imagesource("a.jpg", fps=23.976).trim(0,239)
b=imagesource("b.jpg", fps=23.976).trim(0,239)
c=imagesource("c.jpg", fps=23.976).trim(0,239)

audio=ffaudiosource("audio.mp3")

a+b+c

audiodub(last, audio)


Or, you could make the slideshow as long as the audio, and simply mux in your mp3 after encoding the video, instead of doing a decode / encode via this method.

Wouldn't movie maker reencode the sound?

If you have an image sequence ready, you can do this with VirtualDub no problem.

Great, more songs on youtube with slideshows...

Is there actual a way to obtain the # of audio samples in a given .mp3 via an AviSynth Script.

The info() function does not reveal any information if the audio is not in an .avi (AviSource() )

If you dont want sound reencoded, make an avisynth script just like has been suggested already (this will ensure its the correct length for the song).
Then load the script into virtualdub, and load the audio from the mp3 file. Using virtualdubs directstreamcopy, audio wont be reencoded.

It should do - what is your script?
:script:

You can also get the # of samples using AudioLength or AudioLengthF().

you can do it with a few clicks using dj 264 gui ^^
selct the image, select the audio , and encode. The result will be a music video with the static image
