audio error importing FLV’s into comp
Hiya people!
I am trying to create some tutorial videos, and the source is FLV transparent video. So far, so good!
The problem i have is that sometimes AE decides either NOT to read the file at all, quoting a stupid error that can only be removed by renaming the file so its shorter than 8 characters. The other problem that I have is that no matter what i do, its very hit and miss whether the file even imports into After Effects or Premiere with Audio! Its fine in mediaplayer, and the source is perfect, but both AE, and premiere refuse to play it properly. A quick reeboot or just waiting 20 mins or so, and then.. perfect!
Anyone got any hints?
BTW.. flash is updated, as are all components.. Its a relatively clean machine as well.

Don’t use FLV (or MPEGs, DivX, MP3 or any other funky compressed file) within editing programs or After Effects. They just don’t play nice together. You need to convert your FLV files to Uncompressed (or Animation codec) Quicktime files before working with them in these progs. Quicktime Pro is probably the cheapest and easiest way to convert them, although Adobe Media Encoder could probably do it as well.

I suppose the question is, what exactly are you trying to accomplish?
If you have greenscreen footage that you keyed out in After Effects, you should be rendering that footage out (using the Render Queue, NOT exporting) to an Animation Codec Quicktime file, using the millions+ setting which preserves the alpha channel. This file becomes your master for all other stages of your work until final output to a delivery medium.
If you need to pull the footage back into AE, use the Quicktime master as it will have 100% full perfect quality. Typically you would just work with your original key rather than rendering it out and pulling it back in, but if there some compelling reason for you to render it out first use Animation Codec with millions+. FLV is a highly compressed distribution format, NOT a working format. As such, pulling that FLV back into AE is a bad, bad idea and I can’t think of any use for doing so.
You should use FLVs for final distribution, such as posting directly on the web or pulling into Flash for integrating into Flash animations. You shouldn’t be using distribution formats for working in After Effects. That is why I said in my earlier post that MP3s, MPEGs, Divx etc. are bad to use – they are all compressed distribution codecs, NOT “working” codecs.

Ahh..
OK.. a bit of background…
I am using footage that has been shot in our LA studio. Its already been keyed and exported as FLV. (www.buzzluck.com for an example!)
Basically i have about 30 flv files, pre-keyed, that i am trying to create adverts / video Faq’s with!
The biggest problem is the cost / time getting the original footage from our designers, out of Flex, onto a few hard-drives (pure HD footage!) and over to us! Looks like i may have to do that though!

Did you say they output the files from Flex? That is a web development app, not a keying application so I am confused by that…
If they encode the files to the Animation Codec, the files will actually be pretty manageable in size. Animation Codec is very efficient and all of the keyed areas won’t contribute to file size much at all. As such, even HD-sized files can be reasonably small. Just make sure they use the Millions+ setting or the alpha channel will be thrown away and you will be stuck with useless files. And make sure they don’t just convert the FLVs to Animation codec files – you need them re-output from the original key in After Effects.
No matter what you do, avoid the FLV option like the plague because it is going to give you nothing but headaches and drastically lower quality on final output.
