Weird Cropping or Resize On Import from DVC Pro
Just a quick question… hope this is the right forum. When I import footage from my DVC Pro deck (via firewire), the system is either resizing or cropping the footage so that it shows up as having a black vertical line on the right and top sides of the frame. It’s not so much that it intrudes on the action safe areas (it doesn’t show up on my QC monitor), but it’s definitely there when I output to DVD or encode for streaming. I’m importing DVC Pro at 1:1, via firewire to an Adrenaline system. I’m not sure if it has something to do with the sketchiness of firewire as opposed to SDI, we’ve ordered SDI cards for our decks, but haven’t gotten them installed yet.
Any advice would be greatly appreciated,
Thanks…Dave Potts

I believe what you are seeing is the underscan of NTSC video. It’s not DVCPro, it’s all NTSC SD formats. Cropping the file in Sorenson is a good way to get rid of it. BTW, capturing firewire video at 1:1 is overkill. Bringing it in at DV25 via firewire is essentially bringing it in 1 for 1. It’s all ones and zeros. Once you get your SDI cards, definitely use 1:1.

Cool, thanks for the help, Jon. That makes sense, although it would be nice if I didn’t have to crop every project I wanted to output to a streaming format. Also, I looked it up, and you’re right… the Avid ingests DV in its native format via firewire. I’m relatively new to Avid, so I’m curious now why I was told to ingest at 1:1. Anyway, thanks for the response.

I personally don’t crop my projects. I’ve found that most people accept the bars around the edges. If the customer insists, I’ll set up a crop. We recently completed a project editing and encoding 32 hour long speeches. I set up a watch folder within Sorenson, and dropped the completed QT files in. It cooked overnight, and in the morning I’d burn the DVD, to include a .wmv. It worked like a charm. We also put all the .wmv files on a server, so the community could access the files.
OT, I was recently in your neck of the woods in the Moore Co. / Ft. Bragg area looking at a job out there. Looks like a nice area.

I probably could get away without cropping in some instances, or just tweak the size of my SWF to compensate. The webpage most of our flash video is being encoded for has a white background.
Charlotte is a couple of hours from Fayetteville, but NC is generally a great place to be, easy to make a living, easy to get around, and easy to get away to the mountains or the beach for the weekend.
