I just Bought chronamator and if i understand correctly i should be using the ntsc withouth clicking on the progressive box.

Also if i understand correctly this should double the amount of frame that i would get while working on the project in chronamator.

I do not see that it seems that every click that i do pushing the film a frame further actualy makes a continuity in the motion apparent in the film. shouldnt i see the motion move every other frame instead?

Thanks for any help

No -

The programme deinterlaces the footage, which takes each of the two individual fields that make up one frame, and makes them into a single picture each (effectively temporarliy halving the vertical resolution).

But because each feild can hold a different image, when there is a lot of movement in the shot, after deinterlacing each of the new pictures will show slight movement.

This is perfectly normal, and will ensure that you are able to pull a perfect key from interlaced footage. When you export the video, it will be re-interlaced, so it retains the original footage quality.

I hope this explains smile

THanks Arctic for the answer.

I think i get it. now what about the progressive check box. should i use it? i beleive to be able to use it you should have a very high definition footage.

Again i beleive that the setting i should use should be withouth the check in the box am i right?

Yes, the progressive checkbox is only for use with de-interlaced footage.

Because your footage will be interlaced, you want to keep it that way untill after you've finished working on it, so don't tick the progressive box.

However, if you had footage shot on a 24p camera, or a 3D animation that was not interlaced, then you would use the progressive tickbox.

I hope this helps smile

In addition to what Arktic said, some cameras can also shoot progressive without being 24p - sometimes they call it 'frame mode'. Basically means that each frame is a full res frame, rather than two interlaced fields.

Interlacing...it's a nightmare. smile
