Why is the output file zoomed in or cropped from the original? RRS feed

  • Question

  • I'm using a GoPro Hero4 Black Edition with 1080p SuperView 30 fps. In the output file, it looks like Hyperlapse has just cut out a 1280x720p segment from the middle of the original image. I was using 1920x1080 resolution for both the capture and settings for the output file. I get the same problem using other resolutions.

  • In order to stabilise the image Hyperlapse has to move its crop window around from one frame to the next to produce a smooth video. This is the effect you see in your screenshot and this is why so much processing is required for each video. If you see a dashcam hyperlapse you might notice that the road ahead stays nice and smooth whilst anything in the car (in my case the wiper blade) moves all over the place.

  • It would be great if there was an option to enable / disable this. In any case where you might want to hyperlapse part of a video, or hyperlapse a video at different speeds and stitch it back together this makes it impossible.
