In order to edit smoothly in FCP 7, I need to convert my Canon 7D footage-which renders to disk as H.264 into, supposedly, Pro Res. Every time I do this however my 720P file size increases 3 times as large. I can't do that and I don't see how having gigantic files like that is going to make my workflow any better. So I need a workable solution to convert Canon clips 720p H.264 to ProRes.

Some guy suggests me Adobe Premier CS6 for editing natively. Some guy tells me FCP X is superior for a nice built in features and transitions and templates that CS6 just lacks. But X has a learning curve. And it requires certain hardware that I lack. CS6 also requires hefty processor cards too for much of its performance. So another one tell me use ProRes LT for FCP 7 for it takes less work for the CPU to process and play my ProRes video than to play the H.264s. However, I’m not satisfied with the quality of LT and I'm prefer to ProRes 422 or 422 HQ. Finally, I turn to Aunsoft Video Converter for Mac. It's really excellent. And it successfully transcode 59.94fps H.264 into ProRes with the original size and the video quality is almost the same with the original one. Besides, it is versatile, which can also convert H.264 or other video formats to Avid MOV, QuickTime MOV, AIC MOV, etc.

Below is a step-to-step tutorial of converting Canon 7D video clips H.264 to FCP7 without size enlargement. Hope it is also helpful for you.
