I've owned a PS4 since mid-February and here is the sum total of my time with the system, on which I own about ten games, five of which get played with semi-regularity:
inFamous: 1 clip, 1'28". This one clip I uploaded to Facebook as a test case and now it also can't be deleted from my system because it's "in use", whatever that means. It finished uploading months ago.
Trials Fusion: 2 clips, 2'52" and 0'48" long. The second clip I made using the new "save video clip" feature after wanting to brag about a run to my friend, and I'm not sure where the first came from.
Watch Dogs: 2 clips, 0'03" and 0'06" long. I've had plenty of moments in other games I wanted to share before but nothing as badly as the recent gang hideout I just cleared out, I thought it'd be cool to show some friends how the game can be played non-violently, especially the ones who think the game is all guns blazing. But when I went to save the video clip, all it saved was 3 seconds of me idling in a car after receiving the mission complete graphic.
I should mention I have the system set to save 15 minute clips of gameplay, so the reasoning behind the lengths of these clips and why they are so randomly distributed (the Trials clips, for example, are from April 30th and May 13th) is utterly lost on me. It doesn't help that this means I can't really play with the ShareFactory app at all either.
Has the video capture stuff been working fine for most everyone else, or am I not alone here? I found a reddit thread but I find that forum so hard to read I didn't get much out of it beyond the OP.
