It's going by the local time on your computer. If you change the time forward or back the amount of time left on the web page changes.

Thanks for the write up with each picture as well. I was wondering what all the tanks were.

PaulW1978: WOW!!!!!
I lived in Louisville in the 1980's, and was just back visiting friends in January. We toured the city to see how much it's changed, and.. in 4 1/2 minutes I just relived it all again!!!
This is groundbreaking work you are doing!! And I bet as a collection of stills, this would play extremely well on full-size movie screens as well. (I bet the Louisville Tourism office LOVES YOU!!)

Thanks Paul, glad you like it! I hope the Tourism office likes it, I heard the Louisville convention and visitor bureau likes it but haven't heard anything from the tourism office...unless they are the same place. I'm working on a new video mostly focusing on the trees in bloom right now.

BJL: The 21x12mm mentioned in the article is a bit smaller than Super35mm, which is 24.9mm wide. So either that is a typo, or JVC is proposing a slightly smaller variant of 35mm cinema format (there are already plenty of variants around!). It is also only a 1.7mm larger image circle diameter than the 22.5mm diagonal of the official 18x13.5mm of official 4/3" format, even if current MFT sensors are a bit smaller than that.
Since many lenses cover a comfortably larger image circle that the format they are for (in particular, longer than normal lenses and zooms at all except their shortest focal lengths), I doubt that vignetting will be much of a problem. Also, mild vignetting in the corners of a video frame could be corrected with "lens correction" firmware.

More info on various versions of Super 35mm.

It's absolutely amazing what they have done! I'm still wondering how many GBs it will take to hold a minute of 4k footage. With the current Blackmagic Production camera that also shoots 4k it takes ~6.66GB to hold a minute of ProRes 422HQ. As impressed as I am with both of these new cameras I think I'm even more impressed with the new features of Resolve 11.

neekoh_dp: Wow, great stuff!
You said to tape the zoom ring, but in many shots zooming was used to good effect. Could you shed some light into this?
My guess is you chose two or more anchor points and framed accordingly and the zoom effect would happen automatically as you moved? It's just amazingly smooth and constant. :)
Or did you shoot at constant wide angle and move your crop in post? I doubt you could set / read off the current focal length with such accuracy that you could actually zoom the lens in increments "by hand" across the shot?
Thanks for sharing.

I recommend taping the zoom ring when you aren't trying to do a focal length change during a shot since I ruined parts of shots by accident before when the focal length accidentally shifted.
For the shots where the focal length changed I did those by hand. For example I would physically move the camera backwards from a building then barely increase the focal length by hand....almost impercevably. Stabilizing footage can do some amazing things as long as you try your best to make things as smooth as possible in camera.

Its a good question for sure. Shooting video with the camcorders I own wouldn't let me shoot in as high a resolution as with a still camera, although there are camcorders out there that will shoot 6k. Also most camcorders don't shoot raw which I really needed with how I exposed the images. I admit there are video cameras that shoot raw as well now. The hyperlapses wouldn't have been possible without a regular photo camera because I physically moved and leveled the camera between each shoot. You could use a dolly for some of them, but that would have been a pain to build up and super expensive. Shooting stills also saves a lot of hard drive space because you would end up throwing away an incredible amount of frames when you speed the video up.
So taking a bunch of stills is significantly cheaper, it's a lighter load to carry, quicker for editing, and the software workflow I used was for still photos.

Paul Janders: Really beautiful work Eric. I'm hoping you can answer two questions:

How much more difficult would it have been to shoot these amazing sequences if your camera did not have a tilting LCD on the back?

Did you choose this GH2 because it had a tilting LCD display?

Thanks for making and sharing these fascinating time lapse images.

Hi Paul, for the vast majority of the hyperlapse type shots the flip out LCD didn't really make much of a difference...I mainly used the EVF for those since I could see the cross hairs easier if the sun was shinning. For the slider shots it helped out quite a bit. I could have made it work without the swivel LCD but it would have been much more frustrating and a little more difficult. Usually the slider was in some sort of awkward angle either low to the ground or doing a vertical move which would block the back of the camera. If the LCD was embedded in the cameras back I would have had to remove the camera and set focus and focal length then reattach and kind of guess what my framing was.
In short is was very useful for maybe half the shots but a flip out LCD would only slightly influence my buying decisions. I used a GH2 because that was the best camera I owned, and the mult-iascpect sensor gave a slightly wider field of view and a little more resolution than most M43 cameras.

RPJG: Lovely, and a nice summary of the workflow!

Does anyone have an idea why he might use After Effects? As far as I know, Premiere Pro can do all of the things he's listed, i.e. "specify the frame rate of the video, trim the video if needed, stabilize hyper-lapses, and export your video into a file that can be read on other computers or editing programs"?

I meant raw photos, It's entirely possible that Premiere would let me do it, I've just never tried it. I do find it necessary to export the raw photo sequence as a video file because the raw photo files play back soooo slow.

Not just some dubious and frustrating self promotion like is mostly the case in previous examples of articles!

THANKS and keep them coming whith this quality! :D

Thanks! The staff at dpreview deserve a good deal of credit for making it readable and and coming back with more questions to help it out. Much appreciation goes out to Shawn and Barney for all their help!

myseventhlife: Thank you for this very informative article! Any advice on the intervals between shots and the total duration in order to capture cloud movement? Regards

The intervals ranged from 7 seconds to I think about a minute and 30 seconds depending if I was shooting fast moving clouds or a day to night shot with no clouds. Thanks!

I had to import the raw photos as an image sequence which I don't think Premiere can do...I could be wrong on that though since I never even attempted it. With After Effects you can change the preview quality to whatever you would like...plus you can mask and keyframe easier if you need it.

Pretty neat, I've seen prinsons from a distance in real life so I have some sort of scale to go by. Creating these photos at night make them seem even more eerie.
