I'm with you on that boat. We might as well smear vaseline on the lens we already have and probably end up with a similar effect, for free.

And aside from that, the prices of these microsoft laptops also include the fact that you can make them a standalone tablet. I dont think the price is that bad considering that it depends on the user. If they think they'll need every feature, the price is quite nice.
Edit: And mate, 17h battery.

Hey.
I would first encode all videos to fixed framerate. Keep the dimensions and a bitrate where you won't loose much info. You can do that with Handbrake or MPEGstreamclip for example. The videos from cellphones usually have variable framerate and it causes unsynced sound in premiere pro when editing.
After encoding, you can just go in the program and edit normally.

Premiumbeat has some freestuff blog posts where you can find neat stuff. You can also follow some of the origins of the assets you find there as they will sometimes release more free stuff.

Keep on collecting them. ;)

Yes. The G85 does have a visual sound meter. ;)

VFX is the way. I would shoot a close up of the guy when hes starting to fall and complement with a wide shot of the balcony from inside the house, with the body already on the other side falling. Or, you can just give the notion that the person fell off the balcony without even showing the whole action. It will depend on the way you cut from one scene to the other.
