ok my problem is that my external monitor has a delay compare to my viewer on final cut if someone experiencing the same problem or it is something on my system

thanks in advance

p.s im sorry for my english"


Unfortunately Jorge, this is the nature of the beast, and the beast being firewire. Unlike the Kona devices... when you go to view your output on an external video monitor, the Firewire output must be converted into a standard NTSC or PAL video signal. This is accomplished by using a DV camcorder, VTR, or converter box (such as the AJA IoHD) as an intermediate link between your computer and your video monitor.
When viewing video with the External Video option enabled, the computer's built-in speaker is disabled (or at least should be) and the audio will play out of the DV device used for conversion from FireWire. You should also know that this external audio is synchronized specifically to the external video coming out of the same converter, and that there is a delay in the sync between video displayed on the computer monitor and audio coming out of a DV converter box.

So when you see a delay between what is on your Final Cut Pro output viewer and what is being recorded/outputted, this is normal. This is because there is a delay in transferring the data via the firewire cable into a video source. All will still function properly and everything should be fine when you play back the master tape.

I know its quite the annoyance but I have never seen such a workaround for this without adhering to a single output source or using a non firewire device (ie. Kona). Hope this helps.
