jittery video on 7D
Hello all I have a 7D with a Carl Zeiss Jena 35mm f2.4 Flektogon lens, but the video is jittery, I am shooting 25 frames/second PAL 1080P and have a 64 Gb 600X CF card, any ideas?? or could it be my shutter speed??
thanks Aaron |

Re: jittery video on 7D
What is your shutter speed ?? Should be 50

Re: jittery video on 7D
Assuming you are using a suitable shutter speed for video, the next question is are you supporting the camera on a tripod or using a rig?
Maybe you are just shooting hand held? Then with a lens that does not have an image stabilisation system ( as in this case) those horrible microjitters are inevitable. Time for a monopod - at the very least!

Re: jittery video on 7D
Too many abrupt movements can accentuate the rolling shutter. Post the video?

Re: jittery video on 7D
why are you shooting 25, are you transfering your videos to film?
Vimeo, Youtube and any other web based video sharing site will convert your video to 30p anyways, and even on DVD/BD digital 24/25 fps will not look good, so maybe try to shoot 30p?

Re: jittery video on 7D
25p would be a natural choice living in a 50 Hz country. We have tried 1080/25p, and the aim is to mix scenes in a HDV 1080/50i program. But we haven’t got any useful scenes yet, 7D mounted on a Manfrotto 503 head, and passing wrong low speed trains looks like when using the wrong field order in interlaced video! I think I have tested all settings in Sony Vegas 11 Pro to get the since playing god. Before the first shoot I was just afraid of getting stroboscopic-like scenes when using to short shutter in progressive video.
24p or 30p wouldn’t normally be a good choice in 50 Hz video, like 50i.

Re: jittery video on 7D
Did you by chance shoot with image stabilization on?

Laurence, the Carl Zeiss Jena 35mm f2.4 Flektogon lens (an old MF lens for the Praktica SLR range of cameras) is not IS.
