quicktime fade in / out

[tb1]

Is there any way to make the sound of a movie fade in in quicktime ? and possibly video as well ?

What you want ca easily be done using Quicktime Pro, Final Cut Pro, or even Livestage.

But, do you mean an Applescript to do it?

I don’t think so!

[tb1]

yes, in applescript.

I have a bunch of movies that are cut plain in the beginning and end. I would like to fade the audio/video in and out. Is there a way i can assign an audio level at a specific frame ?

may be since FCpro is not scriptable, do I have to split audio and video, bring into scriptable application and bring it bank into quicktime ?

thanks

Shameless plug!!!

iMagine Video can be scripted to fade/blend video frames.

I am sorry I can’t help for the sound side of things.

Using QuickTime Player, this will fade a movie’s sound in and out at the beginning and end of the movie. Adjust the fade duration as desired:

–Open this script in a new Script Editor window.

set the_movie to “path:to:mov”
set the_fade_seconds to 6
tell application “QuickTime Player”
activate
open (the_movie as alias)
tell movie 1
set sound volume to 0
play
repeat with i from the_fade_seconds to 1 by -1
set sound volume to (round of (256 / i))
delay 1
end repeat
delay ((duration / 600) - (the_fade_seconds * 2))
repeat with i from 1 to the_fade_seconds
set sound volume to (round of (256 / i))
delay 1
end repeat
close
end tell
end tell

Thanks Jonn8, this method is perfect if you don’t want to modify the original audio track and don’t have big audio files. It would actually be a more precise and efficient script if it would waits for a specific frame before fading out.

Hi:

Can you make the fade permanent, ie, save it to the file?

I was thinking you could make the sound volume of specific frames set to a certain level, but I don’t see the command for that…

Hi,

Have you tried iMovie. It’s FREE. Check out the iMovie help and it tells you how to fade the sound of a movie clip with the Edit Volume. You don’t even need to extract the audio. It’s kind of easy. You just click on the volume line and drag to a frame. One dot represents the beginning of the fade and the other the end. These you adjust up and down.

If you tried to batch process this somehow with AppleScript, then you would need to find the frames for each movie anyway.

Hi:

I want to know if you can make the fade at beginning or end permanent by applescripting QuickTime, not iMovie or LSP. Is it even possible?

Thanks,

Hi,

I’m quite sure you can’t edit the volume of a track at a certain position with QuickTime Player. Never heard of anyone being able to do this (fade) and never found a way myself with QuickTime Player.

I was just thinking that there might be an Apple sample program in C or maybe an old version that can do this with the QuickTime plugin. It’s been a while since I went through those QuickTime samples at the Developer site.
