Using cranking to get 1080p60 then using external audio recording? at DVinfo.net

Jack Zhang · December 20th, 2007, 10:27 AM

Since the EX1 supports cranking and the sensors are capable of 60p, wouldn't cranking the video to record cranked 1080p 60p in 30p and using external audio recorders and speeding up the footage in post make the EX1 a 1080p60 camera?

Has anyone tried this? Are there sync issues?

Unfortunately the EX1 only overcranks to 29.97 fps in 1080p mode.

and when your over-cranking to 720p60 it disables audio. You can shoot in 60p and not over crank it. It is very smooth.

to maximise the resolution perhaps recording at 30 fps 1080i then deinterlacing would get better results? You'd get more horizontal resolution than 720p with a loss in vertical, but overall you'd get more pixels in total! Whether that would actually make a difference or not, i don't know...

If you shoot 1280 x 720/59.94P does it record audio as well?

I assume it plays back 1280 x 720/59.94P on the camera but is it as simple as taking this footage into Vegas Pro 8 (which I am using) and putting it into 1280 x 720/25p project and it will preview slowed down?

How does the workflow go if you were to use 1280 x 720/59.94P to shoot overcranked footage?

Didn't remember that part of the brochure that stated 1080p cranking framerates clearly... For a while I thought it was actually possible. Never mind.

And so we still wait for a prosumer 1080p60 camera.
