The main issue here isWhat very cheap camera might introduce people to high speed video analysis of athletic motions such as golf, tennis, baseball, etc. ?
The issue of a fast shutter speed to reduce motion blur is very important. What is the shutter speed of the LX7 and FZ200 in high speed video mode in bright sunlight? As for many other AUTO exposure control cameras, I have tried to find that information and could not.
Since this shutter speed information is basically never
available for high speed video mode with AUTO exposure control cameras, how can you get some idea of the shutter speed? Look for Youtube or Vimeo videos that might show the faster shutter speeds. Since more high speed video cameras have probably been purchased to video golf swings than for any other application, golf is a good place to look. Search - camera model + golf + high speed video
, etc. Side view only, in bright sunlight.
For example, this video for the Canon Powershot ELPH 100HS of a golf swing from the side on a bright sunny day
shows small motion blur and would be very useful for examination of many athletic motions.
I have looked for similar videos for the Panasonic LX7 and FZ200 but could find none. Can you find any HS videos clearly showing the best motion blur?Resolution
While we all prefer attractive, high resolution videos, for accurately
seeing tennis rackets, golf clubs and the important body parts, hands, arms, etc. low resolution video is adequate for the analysis of athletic motions. https://vimeo.com/user6237669/videosJello Effect
- For higher resolution cameras the extra lines of resolution are likely to increase Jello Effect distortion from the 'rolling shutter
' readout process. Can't find JE distortions in the specs or reviews for HSV mode - JE distortion has to be tested under similar conditions. Cost
- Also, there are many people who might give high speed video a try for, say, under $150, but fewer people who would pay over $300 to give it a try. These Canon Powershot ELPH 100HS cameras are now available for under $150 new and under $100 used. About what is the price for the LX7 or FZ200?
(I don't know how to get and display one frame from the above Youtube video in this thread - appreciate information on how to do it.)
