Shutter speed
Changing the shutter speed during movie shooting is not recommended
since the changes in the exposure will be recorded.
When shooting a movie of a moving subject, a shutter speed of 1/25 sec.
to 1/125 sec. is recommended. The faster the shutter speed, the less
smooth the subject’s movement will look.
The minimum shutter speed for shooting movies at a high frame rate will
be 1/125 sec. for NTSC and 1/100 sec. for PAL.
If you change the shutter speed while shooting under fluorescent or LED
lighting, image flicker may be recorded.
