working on an animated show to be broadcast quality, and wanted to get people's input on how to get the best quality audio.
The VO records are done at a recording studio and are delivered as AIF file at 44.1 KHz. We bring them into FCP, Cut them up; export audio as AIFF to flash animators; the flash animators embed the AIFF files into their animation work; animators export their file as a quicktime movie from Flash; Quicktime Movie is brought back into FCP and exported to for audio mixing.
The original audio was recorded at 44 KHz 16-bit Integer, Flash handles the audio and can export it at 44 KHz 16-bit Integer, so is would there be any issues using the audio embedded in the exported Flash Quicktime movie? In FCP I drop the embedded audio on the first 2 audio tracks and then have 18 other original raw audio clips underneath it. What audio should i send to the mixing guy? The Flash Embedded audio or the original Raw audio from the recording session. If I use the original Raw audio then I have to reline it up to the animation and this takes more time. Can I just use the embedded audio from the flash quicktime movie? It should sound the same and be the same quality right? Does flash add any kind of audio artifacts to it's audio files?
You will always get some sort of audio atrifacting when saving through multiple file types like that. I'm not positive what Flash does with the audio when exporting to quicktime, but I would expect it to be similar to MP3 encoding, and if it makes a difference or not is up to you to decide (it will make a difference, but it's your call if the difference is noticable or significant enough to warrant the extra time of re-aligning the original audio to the animation.
I would give the audio guy both, the QT with audio and the original AIFF file. That way if he has any problems with the QT Audio or thinks the quality has degraded through the various saves, he has the original to work off of and he has the audio in the piece which should make it easier to sync up.
I'm filling a need. Without me there would be no bad examples.
