Interesting! Please expand on the technical details of how you prepared this alternative video.
Well I'm not pro in videoanalysis, just wanted to quickly visualize camera movement vs. movement of actual plasma to check was it just 3 LED flashlights (400K+4000K+2700K) under the bed sheet....
What I did was pretty easy and can even be improved further with same toolset. I used Ubuntu LInux for this (i have to translate names to English so you may find some inaccuracies in naming).
1) Cut the original clip using OpenShot video editor to contain only full screen part of plasma. Shorter video is also faster to process in next steps.
2) In OpenShot drag and drop 'Tresholds' effect from 'Effects'-tab into top of clip in timeline.
3) Right click on clip and select 'properties' and there select 'Effects'-tab. Turn slider, need to click effect name 'Treshods' first, to right up to 1.97 (you may try other values, but this suited best for me)
4) Preview and if you are satisfied, export clip as mp4 with your preferred resolution etc. options.
Actually you are done! In general OpenShot seems simple, but has lots of nice features, like 'greenroom' and 'hanging labels' if you study further.
What I tried also was test 'Deshake' the video using ffmpeg, but video was so shaky that I could not get it stabilized. Didn't want to put time on installing additional plugins that may have been able to do that better.
In general deshaking of video can be done using command if shaking is below certain limits:
ffmpeg -i ECatdemoTreshold097.mp4 -vf deshake ECatdemoTreshold097_20190131_unshaked.mp4
(tried also option 'blocksize 100', but no help)
Finally I converted video to short animated gif, since lenr-forum doesn't let me upload mp4 and didn't want to introduce my cloud storage to whole wide lenr world
ffmpeg -i ECatdemoTreshold097.mp4 -t 45 ECatdemoTreshold097_15.gif
