I export my clips, HV30 24p 1920X1080 NTSC, from FCP. When I import to VisionLab it says it's 1440x1080 PAL???? Then when I render the clip to 10 bit uncomp. the video ends up a tall thin full frame. What is going on here? Help

Are you sure that when you started the project, you selected 1920x1080 NTSC? My first guess is that you accidentally selected the incorrect project settings when you created your VisionLab project.

With the camera connected and on before I launched FCP, I used easy setup. So what setting should I set in FCP before importing and after when I export to QTime? Thank you for your help Axeman

Sorry, I don't mean the Final Cut settings, I mean the VisionLab settings. If you export the clip as "24p 1920x1080 NTSC" from Final Cut, you need to make sure that when you start your VisionLab project, you select the exact same settings for it, "24p 1920x1080 NTSC."

Visionlab read it correctly. The hv30 exports as 1440x1080. The only way to get 1920x1080 is to record through hdmi which I believe to be fairly expensive. Not only that, but you have to record the hdmi live.

yeah i think this is the same with my SONY HDR SR12
in the setting in VLS when i am first importing my video, i type in custom 1920x1080i but it is still @ 1440x1080 so is it best i just select 1440x1080 to begin with please? and what effect will this have on the finished video please?

HDV (which the HV30 shoots) has a maximum resolution of 1440x1080. While some cameras have sensors larger than this (i.e. 1920x1080) there really isn't currently a way to record that amount of pixels on a MiniDV tape - hence 1080i/p cameras will always record footage at 1440x1080 with a pixel aspect ratio of approx 1.33 (which stretches out the frame size to 1920x1080).

As Redhawksrymmer has already said, HDV 1080i resolution is actually 1440x1080 anamorphic (stretched like normal widescreen footage). VisionLab is doing the right thing if it suggests this resolution to you.
