The comparison might not be that realistic. The Nikkor lenses that people are using on the 7D are the early manual ones with an aperture ring, as the 7D body can’t control a modern Nikon aperture from the body.
So a Nikkor lens from the 1960’s to 1980, such as a 50mm prime will cost around $50 depending on f stop. I just bought an early 1960’s Nikkormat complete with Nikkor 50mm f2 in excellent condition for $30.
A Zeiss planar 50mm 1.4 lens is going to cost $725, for $725 you could have a bagful of used Nikkor glass.
I have four Nikkor manual lenses and use them all the time on the 7D, I find them excellent quality. For still photos I wouldn’t use them as they are soft, but for video they are great.

H.264 files are a delivery codec, highly compressed, they are not really a format computer friendly to edit from. When you transcode the footage you will see the files get much larger 4 times the size.
I use Cineform Neoscene which has a great transcoding format and produces a 4.2.2 .avi file.

Rather than wait for the 5D2 firmware, I bought the 7D partly because of the 60 fps and have been making money ever since. If the 5D2 does offer an upgrade, or a new replacement comes out, I’ll get that.

No you can’t select the iso in Tv, Av & P. As previously stated P is full auto so you can’t influence the outcome or see the iso.
In Tv you select the shutter speed but if it is too bright or too dark for that shutter speed, the camera will compensate with the aperture, iso and shutter speed. On Tv & Av you do see the iso being selected by the camera.
Most people shoot manual for movies because shutter speed is important, Tv while you select a shutter speed, the camera will change it to suit the light level, so you run the risk of having 30 fps being filmed with a 125th shutter speed, which might lead to a strobing effect and a boosted iso.
These cameras in movie mode are nowhere close to being a point and shoot. Choose manual for shutter speed, iso and aperture, that way you get consistent results.

They are referring to the maximum wide aperture of the lens, how much light it can gather, so a fast lens to me is anything from f1.2 to f2.8
This type of wide aperture is also necessary to get the shallow depth of field you initially referred to, because as you stop the lens down to a smaller aperture (f16), you increase the depth of field, making more distance come into focus.
The kit lens is also a multi aperture lens, meaning at the widest angle the f stop is f3.5 and as you zoom in, the minimum aperture becomes f5.6.
I also have the Canon 50mm f1.4 and recommend it.

Nikon have really developed their cameras for sports photographers and news photographers, that’s why they have so many 12MP cameras, you don’t need more than that for these purposes. So while Nikon have gone for fast burst speeds for sports and lowlight capability for news, the other thing Nikon attached was video.
Video on a Nikon is again aimed at the news photographer, so they can get excellent stills, then do a quick video of the same story for the newspapers/magazine’s website.
This leaves the advanced shooter who is not in the above professions, no alternative but to go to Canon for HD video in a DSLR.
This also highlights the advantages Canon has in the way that they designed and built their own sensors at the start of the digital SLR revolution, whereas Nikon bought Sony sensors.
I write this as a long time Nikon shooter, who has now got a D300 and 7D systems and a use for all my old Nikkor glass, through the Ebay Nikon to EOS adapters.

Neoscene is a self contained program with no choices for codecs, they have written their own codec for conversion. It takes a 7D, T2i or 5D2 file and converts it from an 8 bit 4.2.0 .mov file into a 10bit 4.2.2 .avi file.
Once converted I import the .avi file, which is a great file for windows based computers into Sony Vegas. I export as full HD as a Quicktime .mov file keeping it as a progressive file using photojpeg at 92% quality.

I use Cineform Neoscene to convert camera files https://www.videoguys.com/Item/CineForm+Neo+Scene+PC/54E4543435F454E4.aspx
and Sony Vegas to edit the converted files.

You don’t say if your a Mac or Windows user. I’m a windows user, a bit in the minority here.
I write a blog on the 7D for video production, one of my topics was a workflow for the 7D and can be applied to other cameras, I’m not sure if this is what you are asking for:

Then youtube videos are exported in that format, depending on what software you have, there might be pre sets for this.
