v4hd + hd express
by andres pardo on May 14, 2010 at 10:17:41 pm
1st question. is there a way to sync the v4hd or hd express so when the final cut starts recording an attached audio device like boss 8 track porta studio starts recording as well?
2nd question. the only way of having all the tracks of audio in hd express is the embedded audio? if yes how can i put the audio tracks in the hdmi if the camera only records 4 and i need to record at least 8.
the thing is that im gonna have a 7d attached to hd express and a boss 8 track record device that is gonna be amazing if i could have video and 8 tracks of audio in sync recording into final cut. is there a way or a device that do that?

You'll have to check the manual for your porta studio to see if it has any kind of sync or machine control capabilities. If the porta studio can record while synched to time code, that's the first step. If you have an external time code generator or if your camera can generate time code, you can then synchronize FCP and the porta studio to record together.
The HD Express has 2 channels of analog audio input, 2 channels of S/PDIF input, and 8 channels of HDMI embedded audio.
The HDX-SDI interface has 8 channels of analog audio input, 2 channels S/PDIF, 8 channels embedded, and 8 channels AES/EBU.
The V4HD has 32 channels of audio input in analog, AES/EBU. optical, and embedded formats.
The porta studio records to a flash card, not a tape. That means you won't have speed drift problems with the porta studio. You could record audio to the porta studio and video to FCP (with a scratch audio track for timing reference), with no direct sync between the two recording systems. You would then import the audio from the porta studio into FCP and line the tracks up manually. You would want some sort of common audio reference to use as a start point for the aligned tracks. This is not an ideal solution, but if you don't have any other way of synching the porta studio, it will probably work.
