This example, removed from the QT 7 Help files: "It is also possible to download and install the QT 7 DVD, with media files already included, so that it is easier for users who do not have FCP 6 or FCP 7 installed to use the program on their iMac computers.
I think Streamclip is the only one that displays the GUI when setting up its MPEG-2 support. The other two more or less just deliver the FCP Cinema Tools to you. That would be one of the benefits of using the Streamclip package over the others. I think it's also their only one to support these settings.
I don't have an iMac (or Mac in general) so I can't really help you out. Another good question would be how many inches are you recording to and editing? If it's a 1080i or 720p camcorder recording the native resolution I would recommend sticking with the native resolution, but if you're compressing down to 720p or 1080p then I wouldn't take the native resolution as it will decrease your quality progressively (or even the maximum quality level you... (depending on your compression settings.)
Date works, and if you stream a FCP media file (i.e. -mov, m2v, or any MPEG-2 compressed media type including Sorenson or SVC codecs in paged AIF or AIFF format in a flexible movie-container file), the file will cue up in the correct output editing window at the right time. Once this file is in the correct output location, the media file will cue up and playback correctly at its original format.
I recommend MPC-HC to your iMac users (One of my favorite apps, period). It plays back natively to AIFF files and captures natively to AIFF files (unless you modify the settings). You can also open and save natively to or from a folder, instead of pulling video files into FCP 4.5/6. Either way is totally fine. d2c66b5586
