jumpy footage
Editing in Vegas 13
Three camera event. All three cameras are Canon HF G10s. Relevant settings were: manual exposure, dynamic IS, 1920×1080, 60i.
There seems to be a sympathetic jump in the footage that corresponds with bass frequencies in the music. The wide shot is more affected, or at least more obvious, than the other two cameras that we use for closer shots. All three cameras located on the same wooden platform. A RODE video mic is attached to the top of the wide shot. Small pieces of foam are under the tripod legs to reduce sympathetic bounce from people walking.
I’ve filmed the same event with the same cameras at the same location for 3 years now. This is the first time I’ve experienced this. I THINK I used to shoot in 30p instead of 60i. Outside of that, I can’t think of any other variable changes.
Thoughts?

Ross, that’s real nasty! I have TWIXTOR and Mercalli and I’m trying to think of a remedy. Ugh….. I can stick it through my system to ascertain if there is anything remedial that could be done. You interested?

Y’know, if I didn’t know any better, I’d say there’s some CMOS, Jello-ing effect coming into play.
Nice conundrum to deconstruct. If I was an AVISYNTH Guru, and I’m not, I bet there’s a Virtuldub ‘filter’ that could be employed.
We’ve been fortunate to have had the presence of John Meyer on this and other boards that is the go to guy on film restoration using tools that his results are simply amazing ????

Hi Ross
This will not help you now – but always turn off dynamic is with the camera on a tripod !
Best,

Thanks for all the input.
Is “CMOS, Jello-ing effect” a real thing? If so, how do I avoid it?
I’ve never heard of disabling the dynamic IS while on a tripod. Why is that?

As I said, it looks like it, not that it actually is.

“I’ve never heard of disabling the dynamic IS while on a tripod. Why is that?”
If you mount the camera on a tripod (or similar stable platform) without cutting the IS,
you risk creating what’s called a feedback loop, in which the camera’s IS system essentially
detects its own vibrations and starts moving around, even when the rest of the camera is completely still.
This introduces motion objects to your camera system and brings with it blurriness. This is one of the key
reasons to turn off image stabilization.Also if you read the manual for your Canon camera – set Dynamic IS it to OFF !

Thank you!
As always, you guys deliver.

I’ve a Canon HFG10 and I never turn stabilisation off and I haven’t experienced any problems. On a windy day on full telephoto my medium weight tripod is far from steady and the image can be seen to be juddering with the wind. OIS helps reduce that.
The only problem I’ve had with OIS is the sometimes darkening of corners when hand holding in breezy conditions as the OIS tries to keep the image steady.
