You're in luck, as the command already exists. oMBERS=1 (or !M for permanent) - Bypass Electric Rolling Shutter correction. The media team as used it for product shots, never thought there would be much external interest. I just tested it on HERO11, but it should also work in HERO10 and Mini cameras. So disable Hypersmooth along with this command and you should be able to do a lot of creative things. |

Hello and thanks a lot for GoPro Labs, is there a way to disable internal rolling shutter correction?
I mean when I have the Max lens in circular fisheye view (without activating the Max lens mod in camera) with stabilisation turned off, only when I hit record the circular vignette starts to wobble to the camera movement, graphic example (GoPro 9): https://youtu.be/XT-fJcrfmzU (github direct links don't work)
As you may know a static object attached to the camera (being the circular rim of the Max lens) shouldn't be affected by rolling shutter as it doesn't move in relation to the sensor; I was told that this is a Gopro internal rolling shutter correction and perhaps also a gyro movement sensibility involved?
In my context, I stumbled with this issue when making a chest mounted gimbal for lowlight/night setup for cycling (stabilisation in post), as the gimbal holds very frontwards the GoPro a wider FOV is needed, as the Max lens has, to avoid a cropped framing. But there's no way to stabilise it in post because the image is wobbling all over for that supposed internal rolling shutter correction. In other words I can't shoot lowlight night video unless the internal RS correction is disabled, which would be quite nice for achieving an all terrain camera (day&night).
By disabling it also opens a broad range of functions for different uses and levels up the professional capabilities of GoPro:
· the use of Max Lens in post stabilisation or just as a traditional circular fisheye for videography
· being able to control Max lens FOV in post opens up the possibility of using extreme perspectives, with that alone gains two key benefits: a) the representation of the camera moving at speed in extreme rectilinear perspectives is much more realistic than narrow FOVs (speed look as fast as it should opposed to narrow and/or compressed perspectives) b) in a somewhat similar FOV relation the wider perspectives help stabilisation look more natural.
· technically any circular fisheye (Max lens being the case) captures more light, although projected in less pixels, so has better performance in lowlight?
· opening to the use of cinema lenses for Gopro mount, right now there's a good anamorphic lens that can't be stabilised because of this issue, people have been wanting to use Gopro for cinema for some time using cumbersome lens mods, so seems like a logical feature for a professional use of interchangeable lenses in the GoPro mount system.
Summarising I've a made downhill cycling video to illustrate some of the mentioned benefits as the speed realism and the extra FOV in a rectilinear perspective with the Max lens, it's a little bit exaggerated to show clearly the point: https://youtu.be/wyPNHbJC-N4?t=203
