1. Enable instant upload for videos
2. Take a video with the camera

Comparing the uploaded video with the one stored in camera roll, we can notice a small differences in the size:

94285782 Mar 19 14:42 Video-2018-03-19-14-40-10_0245.MOV (Auto uploaded)
94317058 Mar 19 14:40 Video-IMG_0245.MOV (original)

or

15991385 AutoUploaded.MOV
15993581 Original.mov

Differences are about 0,01% of the whole size.

I've seen previously that videos get processed/rendered before upload. You see bigger difference with Slow-Mo video. Then "Loading…" and the spinner stays in the foreground for a longer time.

Many things changed in the video. Left is the original Slow-Mo video, right is the uploaded one:

confusing spinner before upload starts (40 sec)	no user feedback during upload	progress only shown on Uploads screen

@michaelstingl small clarification regarding slo-mo. Slo-mo videos are stored as normal videos just shot with higher frame-rate. And along with the video there is an adjustment PLIST stored declaring the region of the video to be rendered as slo-mo part. So, when exported slo-mo videos are probably re-rendered at "normal" frame rate.
