When making a video from single image files whereas each image file should be visible for about one second, it does make sense to encode a video with an extremely low frame rate such as 1 frame per second. For this type of application, every frame rate greater than this would be a waste of resources.
I am wondering if the H264 codec (or any specific implementation, such as x264) itself has any lower limit for the frame rate below which it comes to technical problems or some kind of instabilities. In case there is no problem with encoding, can we expect video players to properly deal with such an unusual low frame rate?
Thanks for sharing your experience!
