I just recently got an old Arriflex III 35mm camera without Crystal Sync Base and got a flickering problem on most of the footage. Before buying it i rolled some film to test it, connecting the camera to the domestic current, with an electric conversor (which right know i dont know what voltage outputs). After the test, i went out to film a project, plugging the camera to a 14.4V Vlock battery, with the 4 pin XLR connector, apparently the camera was working and sounded allright, but i got a red dot on the viewfinder all the time. And when i got thhe footage i had this non-constant flicker, which seems a problem related to the voltage and the power of the camera motor. I heard a 16V ground battery could do better to the camera.
What could have been the problem? Should i get a Crystal sync base, or it is not related to this problem? Thanks.
