I put my hand up and admit I was wrong, the MPEG 2 file that comes from the JVC HM100 does indeed work with multicam…on the timeline…1920 x 1080 50i…2 cameras…no rendering ! The down side to this is if you add even a one second crossfade to the video track you will be waiting 2 minutes for each ONE second to render !
As you can see from my test there is not even a green line let alone a red line above the timeline. As a further test I tried 4 HD camera angles but that was asking a but much from the system and it stuttered.
This was edited on FInal Cut Pro 6, ingested from the SDHC card inserted into a n SD card reader and plays back from the card itself.
I had to test this for Terry who was going to suggest the JVC HM100s and FCP as a multicam workflow for a colleague.
Remember if you bring the SDHC file in via the card reader it will bring it in as separate files unless you filmed one continues take as you would if you are going to use it with multicam.
