Timelapse-ul a trecut, în ultimii ani, prin mai multe perioade de inovații și evoluții tehnologice, decât majoritatea celorlalte tehnici cinematografice, fie că ne referim la partea de filmare, din teren, sau la cea de editare, din birou. Deși nu este o noutate absolută, timelapse-ul ultra panoramic (realizat cu cel puțin două camere, cu obiective angulare), a fost mai puțin prezentat din “spatele culiselor”.
Așa că iată un exemplu de astfel de setup, cu tot cu rezultatul filmării. Enjoy the (ultrawide) view!
What happens if we want to create an ultra panoramic timelapse that covers a wider field of view than the one provided by a single lens?
We can create it by using 2 cameras with wide angle lenses positioned to cover a wider angle.
And that is what we did. We mounted 2 cameras with Samyang 14mm lenses in a V shape to cover an ultra-wide field of view.
The whole rig was assembled in ZenSlider motorized slider to create a moving ultra-panoramic time-lapse.
The complete rig was supported in a single sturdy tripod thanks to ZenSlider PremiumPlate and the RRS BH-55 ballhead. On top of ZenSlider motorized slider we placed a RRS BH-40 with a long Tilta Dovetail Plate.
Finally over the Tilta Dovetail Plate with the help of 2 generic arca swiss ballheads we placed both cameras with the 14mm lenses.
We used 2 different cameras, a Canon 6D and a Sony A7s. It would be better to use the same camera but that is what we had in the field. The different color science and megapixel count of the cameras made the stitching in post-production harder but not impossible.
Setting up the time-lapse motion
ZenSlider controller was programmed in Move-Shot-Move mode to trigger both cameras and move the rig synchronously.
We connected a split cable to the trigger output of the ZenSlider controller to duplicate the signal and trigger both cameras at the same time. On the other side of the split cable we connected the corresponding sync cables to each camera.
We used a single 14.4 volt LIPO battery (10Ah capacity) to power ZenSlider controller and both cameras.
ZenSlider controller accepts from 12 to 24 volt so we connected directly the battery to the controller. But the cameras need a 7.4 nominal voltage so we used DC-DC converters to lower the battery voltage to the camera safe levels.
Wait for our next posts where we will share the final result and the post-production worflow.
More to come on Ultra Panoramic timelapsing very soon!
