I read on the forums that DNxHD is a fantastic codec for editing. So, I encoded a video shot on my iphone (.mov format, 5 GB) using this codec. The resulting file is 25 GB. I want to split it into multiple small files so that it plays well in Hitfilm. But even after googling a lot, I could not find a free mov splitter which does not put watermark. Does anyone of you know of any such software? Or, can you suggest an alternative workflow?
