Feature request: option to only apply lens correction, no stabilization #20

Open avsaase opened 3 years ago

avsaase commented 3 years ago

Basically the title. I think the lens correction works great, and I would like to render a video that corrects the distortion without adding any stabilization. Right now Gyroflow assumes not providing a bblog means the gyro data is embedded in the video.

Thanks!

I'll note it down somewhere. In the meantime you can also add a random gyro log, use low value for number of analysis frames, let it sync to a random place with smoothness to zero and export the undistorted result.

I'll try that. And thanks again for your amazing work.

The lens correction is working well and the camera calibration is easy to work with to setup a camera lens.

I would like to add my vote towards the request to be able to run lens correction without going through the video stabilizer.

Similar to how non-linear stretch is an independent process.

Or perhaps within the camera calibration process itself, since we have the ability to playback the video with lens correction applied, provide the ability to directly save the corrected video.

If you are interested you can already correct any fisheye/curved perspective (without stabilising) with this robust plugin for Davinci Resolve Studio (only works in the paid version of Davinci): https://github.com/roukou3/DCTL It's the Ptgui Dctl file + defisheye.h that has to be copied in the LUT folder, it takes some learning -in Davinci Resolve 16, 17 it has to be done some workarounds to work properly in 4:3 footage- but it's a very polished tool and very fast for rendering; any help just ask me or the author in his Github. I use it for my pre-stabilised GoPro footage: https://youtu.be/WuJv0gcKcQs ElvinC maybe you'll find it interesting as it can work in combination with your Gyroflow, for example I intend to use Gyroflow with a wide angle that's not properly centred in the sensor so maybe a manual lens correction versus an automatic has its advantages where I can fine tune the asymmetry, rectilinear errors, animate with keyframes, etc after being stabilised in a 3D curved projection with Gyroflow.
