I'm going to post this for those still struggling with their JVC GZ-HD7U camcorder in getting their HD content from the HDD to their iMac...
First off, the CD that was included with the unit was incorrect in that the Quicktime component was not even on the CD, yet the instructions AND their tutorial video on their website tells you to install it. So a call to JVC Support (and a crappy one at that where it took me talking to 4 people, the first three not speaking English well at all), and 1.5 hours just to get to that 4th English speaking person to get me the CORRECT CD-ROM sent in the mail to me. It arrived and it certaily was different than the one shipped with the unit (which was new box, and sealed, not an open box purchase). So it matched the instructions and I got the component installed on my iMac.
The postings in here talking about the MPEGStreamclip FREE download are correct - go and get this software, as it is free and it works. I copied the .TOD files via USB to a working folder on my desktop on the iMac then I used MPEGStreamclip to create .MOV files and convert them using the Apple Intermediate Codec (AIC), and they look fabulous! Be aware though, this is HD and each scene file is HUGE in size, so clear disc space.
If your going to do a lot of movies then keep good working space on your local HDD and buy those book drives to archive the projects off of your local HDD... Thank goodness those drives are cheap nowdays!
Hope this helps everyone! So if you're missing the Quicktime component you have to call JVC as it is not anywhere online (they confirmed this for me). You may be able to buy it from Apple, but it was supposed to be included with the camcorder.
Then again Use MPEGStreamclip. It works. It's free...
Get familiar (if you're not already) with basic video terminology such as Interlacing, deinterlacing and what those mean, 24p, 30p, 50i, 60i, 3:2 pulldown conversion, etc... If you're going to get serious about your video projects then there's a HUGE learning curve, what with audio, colors, exposure, frame rates, codecs, codecs, codecs, and computer geek stuff...
Good luck!
