Capturing DVCPRO50 in FCP.
on Nov 9, 2010 at 10:16:49 pm

Hey! So I was wondering... I have video with black bars on the sides of my video, was this caused by capturing at 720x480?

So, I have been shooting on DVCPRO50 on a Panasonic SDX-900 broadcast camera. I believe this shoots 720x486, is that correct? For some reason I always thought it shot 486 lines but the top 3 and bottom 3 lines where black and capturing at 720x480 would just crop the top and bottom 3 lines. Is this so or is it a full 486 lines of chroma/luminance color video?

So the video has been getting captured at 720x480. Is FCP (version 5.1.4) shrinking the 486 video down proportionately to fit 480? This would be multiplying it by ~98.8%. This would explain the a 4 pixel of black (plus 1 or 2 feathered pixels) on each side.

Is my logic correct here?

Am I doing a terrible injustice to my DVCPRO50 footage by capturing it at 720x480?

How are you capturing this video? Details are good like decks, cards, etc.

I'm pretty darned sure the spec for DVCPro 50 is 720x480, just like DV. Only twice the bandwidth and 4-2-2 color resolution, a very good thing indeed.

I see tiny, vertical 2-4-pixel-wide stripes at the edges of DV, too.

If I make an image file in photoshop that is 720x486 and drop it into a 720x480 FCP timeline and resize it to 98.8% it looks exactly the same. Why? And why wouldn't DVCPRO50 be a full 720 wide? Whatever its got going on just looks bad :(
