Can you make an audio file that expires after X days?

[Pat Defilippo]

Hi Dave,

Thanks for your reply! Sorry – I didn’t make myself clear enough.

What I’m wondering is if there is a setting (in Compressor or somewhere) that will allow you to listen to an audio file (an MP3 or whatever is as universal as possible) for ONLY 30 days after it is first used before it won’t play again?

For example, let’s say someone downloads the file on August 15 and opens it right away. Perhaps they listen to it in iTunes, perhaps they listen to it in Windows Media Player, whatever.

When September 15 comes, however, that file will not play any more because it is 30 days old. “This tape will self distruct in 30 days” is what I’m looking to achieve.

Is there somewhere, perhaps during the compression stage from FCP via Compressor, where I can make this happen?

If not, is there another way to do something like this?

Thanks again,
-Pat

Hi Dave,

Yea – your answer is pretty much what I was afraid of. I’m sure the client will understand!

Thanks!

How then does a movie rental work from Itunes? Wouldn’t this be the same thing?

I’m not saying it’s easy or cheap, but surely it can be done give the example of Itunes.

I don’t have any clue though.

[Mike Johnson]

This is done through the programming in iTunes, not through the movie file. The movie file is not standalone – it must be played in iTunes, which contains the programming to expire the movie. Same thing could be done here if a software program was written for the MP3, and if the MP3 was encoded using a proprietary format that the program would read, but others wouldn’t.

I thought you were able to transfer a rented movie to your ipod in which case it would be out of itunes. That’s not the case?

[Mike Johnson]

Still running the basic iTunes engine.

How then did the old divx dvds work? (The ones that limited play that were purchased at circuit city about the same time as dvds first started getting popular, not the codec)

Really you guys can stop answering now, I’m just feeling a little antagonistic at the moment.

[Jeremy Doyle] “How then did the old divx dvds work?”

The expiration stuff was all done in the player hardware.

People are still trying to get this to work – witness DVD-D:
