Just picked up the new iMac i7, 16gb, 2gb video card and Final Cut Pro X. It flys! The issue I'm having is the age-old jittery .mts or .m2ts files from my Sony camcorder. I know I need to convert them in order to have FCP able to import, but what do I convert to? I've tried every format I can think of and the only one that results in a file that is not jittery is .mpg. I'm afraid the quality of the file suffers though and then the final post-edited output wont be that great. I am using Pavvtube, which converts superfast to just about any format. I thought I could simply convert the files to Prores 422, but the resulting file imported into FCP is choppy and it doesn't fix itself after exporting the final edited file. I purchased this setup (my first Mac) just so I could have no issues editing this kind of stuff, but so far, nothing but problems. I know it's likely something I am doing wrong, but so far, I am at a loss! Can anyone steer me in the right direction? Thanks.
