That the sensor_width becomes sensor_height in portrait, is as<br>
Francois writes,</blockquote></div><div><br>NO ! I was actually saying that the sensor width NEVER becomes the sensor height. portrait mode is a rotation of the camera itself. You should never intervert those parameter<br>
</div></div></blockquote></div><div><br>I'm not convinced by this reasoning (any time the sensor height > width represents a camera rotation). Firstly not all camera formats are landscape - some are square, some are portrait. We're not just talking about tracking here (which I agree most of the time is done with landscape formats), but we're talking about blender's camera model in general, and this should be more flexible. I should be able to use blender to match output from my 6x6 mamiya or my half-frame olympus pen! ;)<br>
<br>The other thing is that bringing the idea of a camera rotation into blender's camera model complicates and confuses the issue - rotation is a property of the object and has nothing to do with the lens/film back.<br>
</div></div></blockquote><div><br>if you set your filmback correctly the camera will rotate by itself when you'll track it (yes I meant the object in 3d space) and if you do the lineup manually then you'll rotate the camera in 3d space (thats what I meant) if you have a 6x6 or 36x24, no matter on how your camera is in 3d space you should and have to respect the sensor size and parameter.<br>
The other reason to have all parameters is because some camera do not use the full surface of the sensor. For instance the camcorder Canon HF10 has a sensor of 4.54x3.42. But the actual used surface is 4.54x2.55 (px ratio 1.0, resolution gate 1920x1080) I would believe the full sensor is used in case of photo mode perhaps. RED is having same kind of stuff depending on the recording resolution.<br>
