Thats why we buy good equipment and software. Be prepared for 2 day render times with anything but. Nothing free is any good.Sorry if this has already been covered but I am having frustration with editing 4K on a fairly new Dell business machine. Is there a thin free editor app that works well with 4K. I have tried the GoPro free app but it takes about 6 months to render video. The video comes out great but I requires a half day to edit a 5min video. Any advice?
