I had shot test for Time-lapse built in function on the GH3. It was fun because it was so easy to do it. This function was in Still mode. It could be selected to shoot in RAW or JPEG. This was just a test so I selected JPEG at resolution of 4608 x 2592, a 16x9 aspect ratio and set interval time to 7 seconds per frame. My lens was a single coated Voigtlander 15 mm F 4.5. You could see some of the JPEG frame in my FB page here; facebook.com/photo.php?fbid=575770645782256&set=a.313652865327370.100335.100000479769338&type=3&theater
I brought those files into Premiere Pro CS6 with custom setting to 4608x2592/25fps and imported all JPEG still as an image sequence. Then I used Dynamic link to After Effect CS6 for using it’s ability in holding 32 bit per channel. After that I rendered out from After Effect to QuickTime 1920x1080/25p.
