Blurry movie output but liveview is sharp at x10

Hello,

I am currently on a Green Screen shoot for a short film and we are having some issues. The HD video output .mov files are not very sharp. However, when looking at the subject through liveview at x10 it is very sharp. We cannot figure out why the video files are turning out blury? Could this be because of the .mov compression? Our camera man has done lots of greenscreen shoots before and he is confused as to why this is happening also.

Any Solutions?

What camera? What lens? What settings?

It is a 5D , aperature is at 8 and iso 400

We were thinking it may be due to just the playback in quicktime and converting to prores224hq before editing may help? We were using a lower apearture but since increasing it to 8 we have sharper shots but not always perfect

However we still don't understand that sometimes it can be very sharp in liveview but the quicktime output is not as sharp. What could be the reason for this?

Cheers.

What frame rate and what shutter speed.

Are you viewing the files in Quicktime or the editing software? What software / platform are you using? You mentioning ProRes makes me think Final Cut and Apple.

Quicktime used to display DV quality files at half-resolution to help editing performance, but I haven't experienced anything like that with HD footage.

Hi,

We have tried viewing in Quicktime, vlc, after effects and fcp all look the same. It only looked sharp when viewed through the camera at x10. It was 25fps, i don't know the shutter speed off hand just now.

Post a sample?
