which takes my editing/post workflow from glacial to merely slow
Just a few suggestions, though you probably know all of these.
In my attempt to speed up fcp 7, I put my sequence settings in rgb for our early cuts then when finished go to YUV precision 10 bit for final.
Also if your having the gamma issue of prorezz to fcp and back out to prorezz with the tone and color changing, go into the sequence settings hit the advanced tap and set the gamma setting from automatic to none.
This will keep the files looking the same from input to output and seems to speed the system up.
(For anyone transcoding to prorezz also go into the quicktime settings and set gamma to none instead of automatic. You can do the same in Cine-x, or in wondershare which we use for transcoding mp4 camera files).
I know I'll eventually have to change out of 7 but won't do so until it just becomes none workable.
I really, really don't like fcp X and if I have to go to another learning curve will probably go to AVID. I bought premier but most of the houses I lay work off to don't work in X or premier so I have to either stay with FCP 7 or move to AVID.
I'd move to Apple. Not because i have Apple or because I know it but because most of the market you will be delivering to use Mac products.
Personally I know that PC computers, Android and Microsoft pads and phones are as good if not better than Apple. The problem is Apple is seamless between all of these devices.
That seamless system makes working very easy and takes much less time on set up.
I was so pissed over fcp x that I almost moved to a pc and was ready to wash my hands of Apple, but I'm still using and making money with FCP 7, know the software in and out and even though it's old, with small QT upgrades transcoding for pads, phones, screen and web is very easy.
