Since my first time lapse test I've been wanting to do something more so over the last couple of weeks I've been shooting when conditions seemed ripe. The first 1:40 is shot with the Canon 7D and mostly photo time lapse with a few exceptions. The rest is mostly shot on the little technological miracle called the Canon HFs100 and are comprised of video time lapses I shot earlier in September.
In the original photo time lapses there was a significant amount of flicker caused by fluctuations in exposure when the camera is set to an auto mode. Day to night time lapses are difficult and I've since learned that shooting in Aperture Priority mode is the way to go. Click here for more details. To get rid of the flicker I used a free deflicker available for VirtualDub.
The verdict: Well as much as I like the Canon HFs100 it can't stand up to the 7D. Simply put the 7D enormous sensor (APS-C) in comparison to the 1/2" sensor on the HFs100 is like comparing 35mm film to 8mm film. I won't be mixing footage from the cameras unless I have to. Although the 7D is well short of Canon's 5D Mark II, it's still well ahead of any video camera within $15K, as far as image is concerned.
I used an intervalometer for the photo time lapses and compiled them in a handy freeware package called VirtualDub, which I think is the better than After Effects in many ways for assembling a photo time lapse. For a good tutorial on VirtualDub go to the timescapes site for more info.
