My EOS R7 with the 18-150 kit lens is having major issues relating to the video footage it produces. I primarily shoot videos of trains and railroading environments. In the footage I record, when the train goes by there is a horrific shake that goes throughout the entire image. Sometimes it's jello, others not. My first thought was this could be related to my (now old) tripod, the Davis & Sanford 7518B, and upgraded it to the Manfrotto 546BK-1 with MVH502A head. For the 546BK-1 I have the rubber feet on, not the spikes and everything is tightened adequately. The 546BK-1 also weighs 12.5 lbs so the weight of the tripod is likely not a concern to the problem. To my surprise, the upgrade barely helped and almost every single video I record has the shaking. I also tried the EOS R7 on my photo tripod the Manfrotto Element MII and that ended up having the worst shaking out of the three tripods I tried. I have also tried updating the firmware on the camera, changing the way I have it mounted to the plate (normal vs. sideways), and trying the various video quality settings, all IBIS and Stabilization have been disabled along with the Auto-Leveling yet to no avail with the same results. Compared to my old video camera, the Sony AX53 Camcorder the difference is monumental. Footage shot at the same locations will be great on the AX53 (a little shake but nothing stabilization in editing can't fix) while the R7 will be a violently shaking unwatchable mess. Same tripods, same spots, drastically different results. I accept that there will always be an amount of shaking in a video of a train going by, but not to the amount that the video is unwatchable and has to be deleted. Any help would be appreciated for the issue I have occurring, Thanks.
