Why is RodeLink Filmmaker Kit only 44khz? Movie standard is 48khz.

I know that movie standard for audio in movies is 48khz 24bit.

So if I must start a new audio movie project in Pro Tools I must set it at 48khz 24bit.

Why is RodeLink Filmmaker Kit only 44khz? In theory shouldn't it be the audio recorder device to set the max amount of kHz aviable? For example the zoom h6 can record up to 96khz.

Now, there is a problem because I must work in Pro Tools at 48khz 24bit for movie production and as far that I know if I import 44khz audio files into a 48khz session it will convert the file, so it will increase the playback speed (or slowdown I do not remember). But it will -change- the playback speed because of the conversion.
But I do not know: is this change enough big to cause problems?

So there is a solution for this? Is the RodeLink Filmmaker Kit really indicate for movie production?
I wish to buy it so I really wish to know more about it.

Thanks a lot for help.

Not a Pro-Tools user, but pretty much every audio editor will allow you to resample any audio track from one format to another WITHOUT changing the playback speed. You should be able to do this too with Pro-Tools too.

It is a bit odd that RODE went with 44.1 kHz instead of 48 kHz, but I have no clue as to why they made this choice.

Hello Dan, let me explain how the RodeLink actually works (and for that matter any digital wireless system). The 44.1kHz sampling frequency is just a means by which the encoded (digital) signal will be traveling from the transmitter (worn by the actor) to the receiver. The digital data sampled at 44.1kHz travels from the transmitter to the receiver, where it is then CONVERTED to ANALOG audio, so you could record it with your recorder at ANY sampling rate your recorder supports (44.1, 48, 96 kHz etc.) Rodelink does not have a digital output, it has an ANALOG output, so don't confuse the frequency of 44.1kHz digital audio which RodeLink uses ONLY for transmission, with the sampling frequency by which your recorder or mixer records your audio. Hope that helps.
