Hi all,

I just completed a short film with the Canon XLH 1 camera. It was shot at 25p in extremely low light situation and the shutter speed was set to 1/25. The film is intended for 35mm transfer. Has anybody had any experience with transferring material shot at 1/25 shutter speed and seen it projected?

Thank you
ps. I know about the image blur but could not find the difference that noticeable between 1/50 and 1/25

The faster the movement on screen, the more noticeable it is. I think you'll find that most people can easily spot the difference.

For a filmout the added motion blur will tend to make the footage look more "video-ish" than film.

As long as you have no fast movement in the frame, you should be okay with motion blur.

For a filmout the added motion blur will tend to make the footage look more "video-ish" than film.


Actually, whenever I have to shoot interlaced video, I try to use a 1/25 shutter (where available) as the slight motion blur helps reduce the 'video' look

That's interlaced capture, which has different motion artifacts than progressive capture, especially when converting to progressive display.

In that case, you should be fine. It sounds like you don't have a lot of fast movement, which is what reveals the shutter angle. What you have is the equivalent of a 360 degree shutter, which lets you shoot with no danger of skipping -- you get blur instead.
