Hi there,
I was wondering if someone can give me some info. I have been shooting on an EX3 in 1080P30 for the last year or so. Mostly composite stuff, some interviews and other event promo stuff. 90% ends up as web releases, that I encode in 720p H.264s.

I was messing around with some of the different settings on my camera. And I realized that I like the way the 720p60 looks particularly when i pan or there is movement.

I was wondering in what circumstances other people opt for 720p60? I guess it might be a good option for composite work because there seems to be less blur in any subject movement.
But would I get a much higher render time?

Anyway thanks for any insight you might have into the two workflows and their advantages....

p60 on the web looks GREAT.
Just don't forget that you are passing double number of images/sec. You will need to give more data rate to your web clips.
Going to small size web video, is almost always to go 720 than 1080.
Downscaling 1080 is always more complicated than 720.
The Ex-1 has an 720p30 option that is great for SD and web video.

720p60 is good for fast motion as you've discovered. Sports, Fast pans, etc. 1080p30 is good for slower motion, talking heads, were you're going to control pan speed (just as people do with 24p), were motion blur desirable over temporal resolution.

I guess i might try a few of my projects in 720 and see what kind of results i get in terms of render time and final size of the video projects.

What is the process when I mix some 1080p30 into a 720p60 sequence. Is it just skipping every second frame? How will that effect the quality of the 1080 footage? Of course it bumps up work time with the required rendering.

I did a quick test and couldn't see any issues immediately...

If you need slo-mo shots for your project, the 720 overcranking feature smooth's out some of the issues you might have with motion blurring.

What ever you drop onto the timeline sets the sequence. So if you drop your 1080p first, your settings will be based on 1080p. If you drop the 720p first, it'll set it up for 720p.
