You know those videos which show a whole day’s worth of footage in the space of a few minutes? Well they’re called timelapses and iShowU Instant can create them too! Granted they’re with screen recordings not beautiful starry skies or stunning landscapes, but we still think they’re pretty cool.
Check out this video by Roy Korpel for an example of the kind of timelapses you can create using screen recording software like iShowU Instant.
How to record a timelapse
In timelapse videos, frames are played back much faster than they are recorded, so to accomplish this in iShowU Instant you will need to adjust two settings: the capture frame rate and the output frame rate. The capture frame rate can be found on the Video tab of Advanced Mode and control how many frames are recorded each second; the output frame rate can be found on the Output tab of Advanced Mode and controls how many frames will be shown per second when the video is played back.
Having a lower capture frame rate and a higher output frame rate will result in a timelapse video. Alternatively, having a higher capture frame rate and a lower output frame rate will result in the opposite: a video where everything happens in slow motion. It’s worth mentioning that if you record a timelapse video you won’t be able to record audio; just video.
Choosing your frame rates
Here’s a few examples of capture and output frame rate settings and what kind of speed up/slow down you can expect when using them:
|Capture Frame Rate||Output Frame Rate||Speed Multiplier||Duration of video recorded for 5 minutes*|
|30 fps||30 fps||1||5 minutes|
|15 fps||30 fps||2||2 minutes 30 seconds|
|6 fps||30 fps||5||1 minute|
|1 fps||30 fps||30||10 seconds|
|1 fpm||30 fps||1800||0.16 seconds|
|30 fps||15 fps||0.5||10 minutes|
|30 fps||6 fps||0.2||25 minutes|
|30 fps||1 fps||0.03||2 hours 30 minutes|
|30 fps||1 fpm||0.0005||6 days 6 hours|
*Actual duration may be less depending on ability of your computer to meet the desired capture rate.
