FFMpeg crop filter doesn't change orientation
What's happening here is two things:

1)your video is portrait but stored as a landscape matrix and ffmpeg is applying autorotate so that all players natively display it in what ffmpeg thinks is the correct orientation.

2) the video has a PAL DV aspect ratio of ~1.09, so after the autorotation and aspect ratio correction, 568 x 320 is autorotated to 320 x 568 with 1.09 scaler being applied to both W and H.

Try this, instead:

ffmpeg -i VID_1438833296.mp4 -noautorotate -vf setsar=1,crop=568:320:0:0 -metadata:s:v:0 rotate=0 -c:a copy out.mp4
