Hi , I just got some Super-8 Vision 2 200T Processed and Telecined and all my footage has a flicker in the shadow area ( you know with that old line movie look ) . What has caused this problem ? Please help as I'm shooting a short in the next few weeks on Super-8 .

What kind of camera do you have?
Did you have it checked?
(Guillotine shutter ?)
Changes in exposure?


Lots of things can cause this including bad processing, however I doubt this is the case for you.
The best thing to do, especially before shooting a film, is have your camera serviced. This is something you should always do after purchasing a super 8 camera. Most of these things in use today were made before I was born! Also, read up on your camera so you know all the ins & outs. Read up on exposure techniques.

Other than that, tell us the circumstances under which it was shot. Maybe someone with more experience will be able to pinpoint the problem.

Good luck on your short. :) -Jonnie

Check to see if the filming speed is consistent on your footage, does the action you filmed moved smoothly, or does it speed up or slow down? Is there any image jitter?

Either one of those could imply the camera was having trouble advancing the film smoothly.

If neither of those two conditions are apparent, then it could be the result of using a small shutter angle and or shooting at 18 FPS.

Anymore info about the footage or transfer you can share?

Hi , Footage is smooth . No slowing down , no jitter .

I've heard that a transfer at 18fps can give a flicker . Also it's only in the shadow detail .

What kind of transfer did you get? If the film itself is fine then...well maybe the transfer sucks?
This is a link to a discussion which may help you about understanding where flicker comes from:
filmshooting
This is a link for good S8 transfer at great price:
single frame transfer

I take no responibilty for these dudes, however. Read it and see for yourself. Hope it helps.

try another camera, or test your camera with some 64t and view the results. Later nizo cameras have a rubber drive belt that stretch over time. It could be the belt slipping within the camera and not exposing the film at a constant exposure. i am probably completely wrong, but i will always tread carefully with any nizo sound camera. Its been a long time but i think the belt drives the claw and or the drive for the cartridge
