Re: Camera .MOV to .mp4 or .AVI _ Your Considerations?

I would want the other players to view on Kinovea (free, open source) because it has many capabilities. For example, Kinovea has a count down millisecond time scale, "0 milliseconds" can be set to ball impact! Some of these player may eventually become interested in stroke analysis.
First thoughts for options:
1) View on Kinovea - but no video file saving conversions - distribute match original recordings to other players on small SD cards.
2) Get another camera that outputs .AVI. It must be low cost and have a fast shutter that limits motion blur as the AiptekAction was designed to do. (I would expect the fast shutter speed to be very hard to find for low cost.)
(My use of Dropbox has been very minimal, once or twice a year, usually receiving files.)

VLC will play the original.mov file, as will Quicktime.
About 10 years ago there was a security issue for Quicktime for Windows PCs. Apple suddenly stopped supporting it for Windows PCs and I stopped using it. Has that changed?
Kinovea will still view the .MOV video with single frame and allow some of its capabilities to help in viewing. I'd like to get the players to try Kinovea. (free, open source) Viewing is OK but saving video analysis as an .AVI is not workable.
For years I've been interested in tennis strokes. My Casio Ex FH100 outputs .AVI files. I never even noticed saving .AVI files increased the video file sizes of my short videos of single tennis strokes. Often only 1-3 seconds was recorded. I'm impressed with what Kinovea can do.
Video pauses on selected frame, shows text identifying one sub-motion that's happening. Go full screen. You can use the countdown timer and single frame through all sub-motions and do your own time line for the many motions seen in this serve. To single frame on Youtube, stop video and use the period & comma. The 4 second pauses last too many frames to single frame through, play through them, stop and single frame through all motion. Look for internal shoulder rotation.
