I only did a little trial bit with FCP, then went with the Adobe suite because of the related programs. I'm a one-man operation doing all stages of production so having my NLE, effects, grading, audio, encoding & authoring programs all pretty much talk & play nicely with each other is huge. Especially now the Direct Link from PrPro to Speedgrade for grading ... slick & quick & possible any moment in a project without waiting hour/s for proxy/DPX/EDL outputs/inputs/returns.
Never looked back. And parts of FCP looked handy ... just only handled part of my needs.
I am just wondering about your experience with final cut pro and adobe premiere and which you like better and why.
I've posted this in other threads here: I've tried the Final Cut Pro X 30 day trial on my old Mac Pro 5,1 (heavily modified) and my new Mac Pro 6,1 (8-core, D700s). I have a specific benchmark that I run on an NLE when I'm testing it: how long does it take to export one of my movies to a 720p h.264 MP4?
If we assume the length of the movie is represented by 't' (for time) -
The old Mac Pro and Final Cut Pro X 10.0: 2t
The new Mac Pro and new Final Cut Pro X 10.1: 1/2t + epsilon
The old Mac Pro and Premiere Pro CC: 1/2t + epsilon
The new Mac Pro and Premiere Pro CC: 1/2t - epsilon
The newer version of Final Cut Pro X is substantially faster at exporting my movie than the older version. But Premiere is still faster than it is. Also, Apple still can't get the whole "edit the source footage raw" bit right; my source footage is all spanned-clip AVCHD, with files that are over 4G a piece. FCPX can't just open those raw, it insists on putting a MOV wrapper around the footage. There's no transcoding happening, but the file I/O for those massive files slows the whole process down significantly.
Because I don't have years of experience editing with NLEs, I'm not married to any particular UI. FCPX's UI is ... strange, but I didn't find it too difficult to become used to it. If it were faster and more efficient for what I do, I'd reconsider it. But for now, it's all Premiere.
