actually, you're wrong. i work in a post production facility and the video editors (using Avid Adrenaline systems) actually request that I give them a 48kHz, 16 bit file. why, must you ask? ever worked with Sony Digital Betacam or Sony Betacam tape/recorders?? They work in either 48kHz, 16bit or 48kHz, 24bit. Most post production facilities that are not taping to 35mm and/or doing work on digital recorders that support up to 96kHz during production, are using tapes like Digibeta, beta, DV Cam, etc. And if you're shooting production audio on 48kHz, you're gonna have to edit it at 48. Hell, I don't think that the Avid editor's software at my work (Avid Media Composer Adrenaline) supports higher than 48kHz. And also according to the specs on Apple's Final Cut Pro (another popular video editing program in the business) it only supports up to 48kHz as well. Also, not to mention, if you are using licensed music they either a) come on red book CDs or b) hard drives that contain 48kHz broadcast Wave or Aiff files....trust me. this i know for sure.
HDTV is 96khz 24 bit
DVD is 96khz or 192 khz 24 bits
Digibeta are past...Go shoot dating shows in vegas with them.
And for the final cut pro...and new avid you are so wrong!
Not to mention that Nuendo Pro tools and sequa is where you work on sound track dialoge FXs.If you mix audio on video production soft you got yourself the wrong job!!!
I understand the licensed music people use ar 48khz.DOn't argue about that.
