Hello all,
Like probably a lot of you I encountered distracting vibration issues in my action footage and started exploring image stabilization options.
After going through this forum and other resources here is a summary of what I found and some question for your review, I hope the ensuing discussion will benefit other users. Any competent correction or answer would be highly appreciated.
Hand jitter can introduce 2 problems in video, blurry individual frames and frame-to-frame jitter.
We cannot correct for blurry individual frames in post-production (incl gyro stabilization).
Since optical image stabilization is not available in Git2, we could minimize frame blur by filming with enough light (to have a fast shutter speed) or setting a fast shutter speed manually.
Q: Does the frame rate have an indirect influence on minimizing frame blur, I thought I read somewhere that having 60fps might be beneficial over 30fps due to higher needed shutter speed?
Frame-to-frame jitter can be corrected with EIS (Electronic Image Stabilization) ie our gyro stabilization or after the fact in software like virtual dub deshaker or adobe premiere warp stabilizer.
Advantages of gyro stabilization include enhanced stabilization due to movement information from the gyro sensor and getting the stabilized output written directly in the camera.
Drawbacks of gyro stabilization include reduced field of view (similar to sw stabilization), battery drain, possible resolution change and effects of image quality.
Q: What percentage of field of view is lost when using gyro?
Q: How much of the real resolution read from the sensor we get when using gyro and in which cases we start to loose resolution? Is this resolution dependent ie is the gyro in 1080p more effective than in 1440p 4:3?
Q: Does the frame rate affect gyro ie is it as effective in 1080p60 as in 1080p30?
Q: What are the effects on image quality?
Q: Is the gyro prone to similar warping effect as software stabilization?
Thank you for your contribution!
