It's probably best to go with a standard NTSC or PAL video resolution that will transfer to video. I make Video CD's (both VCD and SVCD formats). The digital video must conform to strict resolution, data rate, and sound standards. For the best info on this try www.vcdhelp.com. If you can, make a video CD instead. It is more durable and will probably look a little better than video tape. Also if you need to transfer it to video tape you can do so and still retain the high quality master disc. Plus you can play it back on both a computer and a properly equipped DVD player (and of course a VCD player). Many DVD players now have this capability and vcdhelp provides a list of them. MPEG-1 (VCD) NTSC-compliant video, for example has a resolution of 352X240 pixels with a data rate of about 1124K, and stereo 16-bit 44KHz sound at 224K bitrate. You can fit about 1 hour of video on a video CD using this format. MPEG-2 (SVCD) NTSC-compliant video has a resolution of 480X480 with a data rate of about 2200K, and slightly higher quality sound with the same spec as above except it's 48KHz sample rate. Note the vertical resolution is doubled, and will yield a better looking video at the expense of less time on disc.You can fit about 30 minutes of video on a video CD using this format. MPEG-2 is also the format used for DVD, with even higher resolution and data rate (704X480, 5MB respectively). Hope this helps. Krel
