I thought that film was made from celluloid, comes in reels, and is the traditional medium used for making motion pictures or movies. But maybe I'm just being pedantic too? :)

Mr. Hunter? You´re a Major Player on DVinfo.net, DIGITAL VIDEO, and you´re gonna poo-poo the acceptance of digital video as a viable filmmaking medium?

Pedantic? Slightly.

Hi Donovan. Sorry, you misunderstand my point. Film is used to make movies, so is video. To say that the end result *must* be called a film, to the point where people start *correcting* others' terminology, is what I disagree with. But I agree it's pedantic. :)

Higher shutter speeds reduce motion blur in the individual frame...so when you slow it down, you have a clearer image. No, 30p will not yield the same result as 60i, you need 60i so you can deinterlace each field set and give 60p which you can slow down to 30p and get a 50% slowdown...if you are delivering in 24p you can slow down another 10%. 30p doesn't help you at all.

Hey All. I've been away on a LONG spring break for a while. Nice to see that people are still chatting in this thread. I have a question about my own technique regarding color timing. If this technique is used what is the color timing of the final 60p sequence? I’d imagine that 2 frame back to back would each store half of the color information then 6 frames wouldn’t have any color information. My reason for asking is that I am going to be filming/recording/taping (whatever you wanna call it) a movie this summer all on green screen. Now I know DV isn’t the best for green screen but I imagine this process would make it worse. Can anyone help me out and suggest a method to make it better.

Also, there was a tutorial I once saw about creating an automated mask that follows a keyed area, so you only have to essentially deal with the spill and a little bit of green around the subject. Does anyone know what tutorial I’m talking about.

I’m sure this question is in the wrong place but… lol its three seemingly unrelated question that do actually relate, so idk where to ask.
