Lets hope that we don't have to do the same on the REDDrives when they arrive, this would be a pain not to be able to use different format selections over the drive.
Any news ?
LOL ... this is like the question of the day.
I'm not freaking out. This is a huge issue, so I'm sure they'll figure out a way to make switching formats fast and easy before too long.
That is, if you downres slightly soft 4k, to 2k, it'll appear sharper, and if you blow up 2k to 4k, you will loose sharpness. If you mix 2k and 4k, I don't think you will gain in sharpness with the 2k material, and more so, your images will be very difficult to mix because they will look quite different.
On the other hand, if you need higher frame rates, well you have to live with diference.
its not a question of sharpness, it's about sensor size and DOF characteristics.
lets say you know ur going to finish in 2k or HD. You might want to shoot 4k for archive but also because it uses the full 35mm sensor. That 35mm sensor however, can make it very difficult to keep things in focus (sometimes good, sometimes bad). So for run and gun stuff, people may want to switch over to 2k windowed to get a half sized sensor with more forgiving DOF.
So yeah, people are asking about focus in relation to DOF, not overall sharpness
would be interesting to know more about this subject. while shooting with dvcpro hd a few weeks ago i remember i had to turn the camera off and on again after switching from 1080i to 720/50p. took a few seconds.
postproduction wise i agree with laguun -it was quite painful working with mixed formats on the same dvcpro hd tape, because selecting the right combination in the vtr menu required rebooting the vtr after every change. so try and error took quite a while ;-)
don't know if switching from 4k to 2k would really help to keep focus.
all the best,
I'll ask Stuart to respond to how this all came about. Today you need to reformat if you change the *project* framerate or change the resolution.
