What format are you uploading. 16 or 24bit, 44.1 or 48,kHz

I was wondering if anyone has been upload 24bit / 48, kHs now that we can.
I know that 16 by 44.1 is such a standard, Just wondering if anyone has had any problems.
Thanks.

24 was accepted up until recent years, then only 16 was accepted. i didnt know 24 is on again...

I keep trying 24/96, but apparently they haven't got the memo. 44.1 and 48 is so um ... old. Not sure why this limitation is.

Your best bet is 24/48. That’s standard for broadcast.

I've been told 44.1k/16bit. They won't accept 48k last I checked.

There is no point uploading 24-bit - that, as well as 32-bit (floating point), are formats you'd use when processing to reduce rounding errors in the processing chain. Though, I did upload a 24-bit track by mistake and it was accepted for what it's worth... (track in question: https://www.pond5.com/stock-footage/96066655).
The same goes with frequencies. We humans cannot hear frequencies above ~20 kHz, and that optimally. Most grown-ups due to various damage over the year can only hear up to ~16-17 kHz and then you have consumer equipment that cannot reproduce even that. The only reason for 96 or 192 kHz is again processing - for example, some EQs work better at these frequencies. Oversampling and anti-aliasing are other aspects, but it doesn't matter for your final master.
When you're done with mixing, processing and mastering, export to 16-bit / 44.1 kHz by first applying a low-pass/high-shelf filter (recommend the latter to avoid phase issues) to get rid of any frequencies above 20 kHz to avoid aliasing (in case high frequencies snuck in or was in the original recording) as they are no longer needed. Also trim bottom to filter out anything below roughly 50-60 Hz as you don't want rumble/bass. Nyquist theorem kicks in and you have a optimal frequency range engulfing with no problem all human audible frequencies using 44.1 kHz.
48 kHz is more rooted in the historic U-Matic SP format from Sony which had to do with analog tape syncing (IIRC), which kind of has stuck since on many video and broadcast systems. It's not needed quality-wise, but providing audio at 48 kHz removes the need for resampling it to target frequency if TV-broadcast/film is the primary target (resampling from 48 kHz to 96 kHz doesn't cause any quality loss, but 44.1 kHz to 48 kHz may but rarely noticeable).
