DVL-Digest 882 - Postings: Index "Strictly DV-L" (was breaking the rules) Field Render Order Image degradation Mini DV Video Tape monitoring sound in post "Strictly DV-L" (was breaking the rules) - Adam Wilt ;-) Cheers, Adam Wilt Field Render Order - Adam Wilt What is the correct field render order for DV? Lower field first. > At work I was always taught to use the upper field first when I am > importing my footage into After Effects. Almost all other capture cards/formats are upper field first. DV is annoyingly different in this way. When adding DV into a non-DV composition or project, you'll usually get better results bumping the DV footage up or down one scanline, effectively reversing its filed order to match the comp. Likewise, non-DV footage (by which I mean footage not captured to DV format, whatever its original source; BetaSP captured through a DVCAM deck or through a DVMC-DA1 *is* DV as far as AE or FCP knows) should be offset one scanline when placed into a DV project.

If your on-disk format is DV, you will see NO image degradation or change by transferring between tape and disk. It's a bit-for-bit copy over FireWire. Cheers, Adam Wilt Mini DV Video Tape - Adam Wilt Is it still advisable to not mix mini video tape between Brand > names?... Is it still good practice to stay with only one Brand to > eliminate the head clog problem?

I've gone 300 record/rewind/recue/play passes on a DV tape before seeing an increase in dropout. Cheers, Adam Wilt monitoring sound in post - Adam Wilt for someone who likes portability, is it viable, or even suggested to use > headphones (instead of, say, nice pricey genelecs) to monitor sound with > my powerbook? I do it. Many people recommend against it because the dynamics of headphone monitoring are not the same as with open-air speakers. If anything the headphones give you a more critical appraisal, revealing every level change and defect that might otherwise be masked by ambient environmental noise. On the flip side the isolation a set of cans provide makes things more intelligible than they would be through speakers. Without awareness of these effects, you might mix a track that suffers from too much finesse over inaudible details yet suffers from an overall lack of clarity. But if you learn to calibrate your ears to these effects, 'phones are a great way to work on the run.
