First, I'm a long time PC user who has recently switched to Mac's and I'm rather picky about the quality of my videos. Problem: I have HD video from a Canon HF S10 camcorder and Canon EOS 7D that looks fantastic on a PC... but looks very so-so once imported into a iMovie or FCE or FCP. I've tried all three programs using AIC and yes I've even tried Apple Pro Res HQ and still end up with very poor quality mov files when compared to the originals. Part of the problem (or benefit of a PC) is that the PC actually plays the original RAW MTS/M2TS/MOV files without any trouble and and they look unbelievable. Where as my Mac has to import/convert the file to AIC or Apple Pro Res HQ... so no matter what codec I use, my Mac produces video that is not even close to what I get out of my PC. My original RAW files are all 1920x1080 60i and are MTS files from the HF S10 and Mov files from the 7D. Even the original RAW Mov files produced from the 7D don't look as good on my Mac as they do on my PC. I even took a SD card with the original files down to the local Apple store to see how they look on a Macbook Pro and they still don't look like the originals on my PC. Also, all my comparisons are being done side by side on two 24" Apple cinema displays that are calibrated. Any ideas as to why the quality is just so-so when compared to the originals would be greatly appreciated. Thanks in advance.
