HDV1 and HDV2 ? What’s the difference, I thought HDV was all the same?

YES there are two types of HDV.
HDV1 is JVC’s format and records at 19Mbs in MPEG-2 with a resolution of 1280×720 pixels (progressive).
HDV2 is what Sony & Cannon uses and records at 25Mbs in MPEG-2 with a resolution of 1920×1080 pixels (interlaced).
Even though the tape looks identical for both formats, the Sony HDV will not playback on a JVC nor the JVC playback on a Sony.
*Canon adds to the compatibility issues with an “F” setting on its camcorders that won’t play back on either a JVC or Sony deck.

Digital ICE with 35mm Kodachrome Slides

Digital ICE will remove scratches & dust during the scanning of your slides, however  Kodak Kodachrome slides contain silver halides.  Since our slide scanners use long wave infrared light, the silver halide particles reflect the infrared light in a similar manner to dust particles.  At resolutions of 1800 dpi, we have found that Digital ICE applied with Kodachrome slides, you may see a slight halo to objects in your slides.  To eliminate this, we reccomend using a dpi of 3600 for Kodachrome slides.
