jitter/flicker problems.

[hideout_tree]

more super 8 problems! not that bad though.
recently shot 2 rolls of tr-ix using a braun nizo 801 for a title sequence to a short. most of the footage was pretty much ok, but quite a few scenes had alot of jitter and some awful flickering as well.

uploaded to ask for any help and tips as to how to reduce this jitter. everything i have shot with a nizo 801 seems to have these jitter problems. also wondered if anyone know what cause the light flickering in some shots?
thinking about selling the nizo to get a canon 814/1014xl camera, as footage ive seen on these cameras have a very steady frame, what do you think?

thanks for any help
(am shooting my straight8 entry this weekend on tri-x and want little jitter and no flickering like in the video above if possible)
