Interested in Video Analysis

[d.girardi]

Good to know that there is some interest in integrating this into phyphox. When the upcoming big update is done, we are thinking about working with the camera, which at first will mostly involve brightness and color analysis. We have internally thought about stepping up to tracking later, but this will depend on whether we find that we can offer some additional value compared to existing app.

Since i work very often with videoanalysis programs (Measure Dynamics e.g.) in school with students and trainees, i can confirm that there are no useful programs for android os. On IOS there is "Vernier Video Physics", that works very well on tablets and phones. But on Android os there is only "VidAnalysis", that doesn`t work properly in my opinion. The only useful program on android os  for analyizing videos is "motion shot" from sony. It makes stroboscope pictures from self recorded motions. Those pictures can be easily analyzed by young students. I know a lot of people, expecially young teachers, wo are very interested in similar programs on androis os as "Vernier Video Physics". This would be a very helpful and powerful instrument for experiments with motions, especially using a slow motion video.

Adding the information that Vernier's app is paid and VidAnalysis do not perform an auto track. You need to touch the object frame by frame to get the data. I even don't understand why they don't use OpenCV to do the job automatically. In my opinion, even if we had a good app for video analysis, will be great if phyphox has this feature too.
