I captured a clip with the BUZ at 720x480 using VidCap32 at
100 KB/frame compression. Since the footage is intended for
adding to DV footage and/or outputting to DV tape, the clip
was recompressed with DV-Soft to make it compatible with
mini-DV footage and was imported into Premiere. Applying
"make movie", using field 1, field 2, or full frame made no
difference - the entire clip jittered (most noticeable with
moving subjects) even without transitions. Trying a 15fps
"make movie" did not improve things. Applying a "speed"
effect, selecting 99%, removed the jitter. I then put a
3-second disolve between two copies of the 20-second clip
and again rendered a movie. The transition had no jitter.
Since then I have found that the jitter can also be removed
from Buz-captured DVavi-converted footage (and it does not
reappear during transitions) by selecting "field options"
in Premiere and selecting either "flicker removal" or "field
reversal". On a TV all three methods appear to be about
equally effective in removing the jitter, but when looking
at individual frames on the computer monitor, "remove
jitter" looks the best. I then tried working with the
original mjpg footage, and results appeared to be similar,
though not quite so good (I did not view these clips on a
TV). Processing time is long, and these solutions may not
be useful for most people, but it does make the Buz useable
for me for inexpensively capturing analogue footage for
editing along with mini-DV material.
