DVL-Digest 1190 - Postings: Index external hard drive How to use 70% zebra? Text glow ? - (2) - (3) external hard drive - "Perry Mitchell" From: Tim Selander I use Macs, so you might not get the same results, but I can guarrantee you that USB will be too slow. I've used external firewire drives successfully, but only when the bridge chip was the Oxford 911 and the drive was 7200 RPM. Non-911 bridges didn't work for me, and a 5400 rpm drive in a 911 box didn't work either. Dropped frames on print to tape. (Capture and editing on firewire drives worked fine in all cases, only the print to tape failed.) How to use 70% zebra? - "Perry Mitchell" From: Rich Is this correct? With 70% zebra I stop down until there are no stripes then open up (one stop) until first stripes appear on highlights. And keep it there.

D1 is native NTSC video frame size. It's 720x486. Orior to the popularity of the dv format, it was the most common spec (ITU-R BTU.601-4). It's still viewed as 4:3, but it's based on 486 scan lines. If you're working with other video systems besides DV, this is the frame size you'll most likely be using for full screen NTSC work. >What doesn't make sense is that NTSC DV is 720X480, not 720X534. Also, >since 16:9 for DV is anamorphic, it too is 720X480, since the DV format >has no other data storage format. > >So, I'm confused by what Adobe is doing., PhotoShop is just supplying templates for the square pixel equivalents of the different video frame size specs (since PhotoShop works with 1.0 square pixels, not the .9 rectangular pixels). Not to have MB jump on my back, but 720x534 is the square pix equivalent of 720x480. 720x540 is the equivalent for D1 720x540 (hence the extra 6 vertical pixels). A lot of people use 720x540 for DV frame size, but 720x534 is more precise. Valerie Text glow ? - "Valerie Shoaps" 534 x .9 =3D 480 .9 is the ratio for rectangular pixels in relation to square pixels 1.0 Make a Photoshop graphic at 720x534. Bring it into a DV project in a NLE that handles PAR's without any bugs (such as Xpress DV 3, Final Cut Pro, Vegas Video, etc... Premiere has a bug, and I don't do Premiere anymore *see below*). Slect the graphic/clip in the timeline, and then "Interpret footage as rectangular". For Premiere, it would be Clip>Advanced Options>Pixel Aspect Ratio. If you're using Premiere, look at pages 133 to 137 in the version 6 manual. They even have a nice photo to help illustrate this much more eloquently than I.
