time play - speeding up (and slowing down)

This action-camera allows video recording with external mic, instead of relying on built-in ones. But it also is built for slow-motion (up to 1/8 of real-time pace in video mode or 'burst' of 30 shots in 1 second in photo mode). That is fine for sporty types of use. But making time speed up (time-lapse photo sequences; time-lapse video clips) may be more useful to me when cloudscapes inspire, for instance. Here is an early attempt (camera took shots at 15 second intervals, so about 240 in 60 minutes). When played back at 24 frames per second as a video, this is the 8 second result.

Day breaking on June 14, 2019 - looking across the south skyline.

Here is the full-size (HD: 720x1280 pixels), uploaded at Youtube instead of blogger constraints.

In other news: here is time-lapse VIDEO (end result is a single video file, rather than a pack of JPG that need to be edited and then saved as video) that shows about 20 or 30 minutes of painting, recorded something like every 10 seconds and played back at full-HD (1080x1920) in 24 frames per second.

And lastly, here is plain old video for 45 seconds, but using the built-in mics instead of external gear (sold separately) at 1080x24 fps, since 720 size requires 30 fps or faster (same amount of visual data, thus file bulkiness: ok to upload from library's fast wifi, but tedious from home wifi)
