Motion artifacts, help!

Right, Martyn. And Patrick, it doesn't have to do with what is better, because what is best depends on the job, the destination of your footage.

When I got my camera, I made the same statement you did! I declared I was going to shoot in 24p because it had highest data rate, and it was 1080, not 720. Bigger is better, and all that.

It made sense and seemed logical, and no one can be faulted for thinking that.

Then some folks here stepped in, explained to me the issues, pitfalls. More importantly I shot footage and through trial and error, and the advice of those around here, I learned that for my workflow 720p is simplest and best, but only because of what I was going to do with the footage.

A perfect example of how to utilize 24p would be if you had a Western Digital Media player, which I might buy for myself. I can shoot in any mode, it will play back from a USB stick or hard drive directly on the player, and yes, depending on the TV and how it transcodes the signal, it should look terrific!

It can also look great on DVD or bluray, I guess, but I don't know how to deal with it for that. If you've got lots of time to experiment (I don't) you might come up with a formula that works for you.

So since the final product is to be put on a DVD (unless the client asks for Blu-ray), what looks best after converting to SD and burned on a DVD?
I am shooting in 1080p 24 but when I post on Vimeo I still have to convert to 720p, so that defeats that setting. When it goes on a DVD it is downconverted to SD, what is the recommended setting with the GH2?

Personally I think 720p is the best place to start, as you do what I am doing, DVD and then some web uploads. I use Vimeo, render to mpeg 4, and it looks pretty darn good.

I think the 24p thing should come with a warning label, it has limited usefulness, IMO. 30p is much better for most folks in this age of web video, but what do we know?
