Except the Z10000 and higher priced camcorders, all other 3d camcorders record in 50i/60i - usually MVC.
The sensor is a native progressive sensor - so the question for the owners of these cameras (JVC GS-TD1, Sony TD10 and later models) is whether this is just PsF - i.e. progressive signal in an interlaced container ?

no there is 2 sensor per camera, so the fact the sensor is progressive or not is not relevant.
the fact is camera makers (and particularly sony who is alos involved with blu-ray) have crippled the low end 3D products to 50/50i without clear reason, knowing that progressive 24p is mandatory for 3d blu-ray.
Is it to protect a "pro" version of these camera ? (the NX3D1 is almost the same as the TD10, but cost almost 3 time more).
an exception is the JVC , while 2 versions where available and only the pro version doing 24p, the pro version was also affordable (less than 1500$). Unfortunately the image quality was behind in reviews.

Mine (TD10) is full interlaced.

No question, great for slo motion 3D!

Any idea which ones do progressive?

The Panny Z10K and Sony HXRNX3D1U

The JVC GY-HMZ1U does a 24p output, but it's in that single file format like the GS-TD1.

Has anyone captured progressive output from any of these using the ultrastudio ? Dashwood has a note on his site that the ultrastudio only captures interlaced over hdmi.
