what is the normal sample rate and sample size for post production? is there any diffrence in sample size and sample rate of tv movies and theaters?
Required delivery for nearly all HDTV broadcast stations these days is 24-bit/48K. Now, that doesn't mean you can't do the sound design at 96 or 192k, but you'll have to dumb it down for delivery. Movies will also be done at either 48K or 96K for final deliverables.
Its a vague question: "for post production?"
The sample & bit rate you work at during post production is a different issue to the sample & bit rate for release/delivery format....
For film, location sound is 24bit 48k poly, I do most FX field recording now at 24 bit 192k, I do sound design/processing 24 bit 192k or 96k or 48k while dialogue editors & foley work 24 bit 48k, We mix 24 bit 48k so my final edit sessions are 24bit 48k
FWIW the 24 bit vs 16bit is as significant as the sample rate... (I wouldn't want to be working 16bit & haven't in a decade or more)
The delivery format depends on the medium, versions of a film soundtrack are created for each medium
- output for film sound neg
- output for HD Master
- output for SD Master
- output for DVD
In the UK, its 48k 16 bit for Television.
48khz 16bit remains the industry standard for both formats. To get you started and and answer some basic (and technical) questions, I'd recommend picking up "Sound for Film and Television".
Standard for any video work is 48k/16b, however your question leaves an open door that I'm offering to shut: 48/16 is the release/broadcast standard, however while still in the postproduction process, the use of higher bit rates and sample rates is preferable.
In any process, the higher the resolution of the source/input the better the quality of the result/output of the process will be.
IMHO, I'd have said 48k/24bit, whether film or telly. Not solely as my own personal preference either - in my experience that's the format that location recordists are delivering rushes at these days.
As Noiseboy said, the standard in the UK is 48 KHz 16 Bit. Sometimes the sound post-production superviser will request 24 Bit resolution as this allows about 20 dB more headroom, but this will always be agreed upon before the shoot. Although many cameras record at 48 KHz, 16 Bit this is likely to change in the future - camera technology is continually developing and storage mediums are also getting maller in physical size but bigger in storage size.
