Question about PS4's recording feature

[Jdevil3]

I've been searching but I can't find a definitive answer to this.
Do we know if you can save your gameplay recordings onto the PS4's HDD instead of directly uploading what you recorded? My internet connection is kinda shitty and I lose connection pretty often so I'd hate it if I lost what I was uploading... And besides, It would be cool if we could store the video (or videos) onto the PS4's HDD without uploading them and then copy them to a USB drive and copy them to a PC to propely edit them and upload them from there...

So... have they ever said if you can save the videos into the HDD without uploading them or not? O_o Has it been confirmed that it's only 15 minutes per video?

Thanks in advance :)
