iPhone 4 video editing
Please forgive any stupidity on my part, my video editing experience has been with 720×480 DV in Adobe Premiere. I only recently made the switch to FCP and I am having a real challenge understanding the different setup presets.
I shot video on the iPhone 4 and want to edit and use SmoothCam on the footage. I have read a few posts that suggest using “ProRes422, (HQ if you use a lot of effects and processing)” – but there are so many options for ProRes422 in setup and I haven’t a clue what the difference between them all.
I’ve tried many of them and every one I choose gives me the “This clip doesn’t match this sequence’s settings …” dialog. When I accept the option to “Change sequence settings to match clip settings” the option to use Unlimited RT disappears. When I say No to the dialog, Unlimited RT remains, but the Smoothcam filter seems to have absolutely no effect on the footage (after a 5-hour calculation process).
I don’t know the difference between the HQ vs. LT vs. proxy vs none of the above. (I do understand that the iPhone footage’s audio is 44.1 and that it needs to be converted to 48 kHz.) And frankly the more I read about the various settings, the more confused and overwhelmed I get.
All I want to be able to do is choose the easiest setting that will enable me to edit and Smoothcam iPhone’s 1280×720/24 fps footage and have the option to use unlimited RT.
My best guess is to convert the footage in Compressor using the Apple ProRes 422 (HQ) setting. But before I invest in the conversion time, am I on the right track?
(ps. I went ahead and submitted a Compressor conversion using the setting I mentioned above and after 20 minutes, the status bar shows no indication of any progress, and the time remaining indicator says “-:–:– remaining” – it is a 30 minute video- how long should it take?)

You’re correct in using Compressor to encode your video to ProRes. Each version of ProRes uses a different data rate. If you search you’ll find the rates. However, the highest to use in this case is 422and LT will probably look the same (LT is a lower rate than 422. thereby, making smaller files). Try both and see. While there are differences in opinion, most advise that HQ should only be used for 2k footage and above.
