Hi Jesus!
Here is the answer I got from Aja:
Andrea:
The XLH-1 will always output 29.97 via the HD-SDI output.
The IOHD is auto detecting the correct format. There is now way around this if you capture with the IOHD. You will have to use 29.97
The only way to output 24 frame out of that camera is via Firewire.

So, the 24F signal is applied just to the tape.
