This video was shot in Illinois on the iPhone 6S using Thalia Live HD/R. Postprocessing was done in Adobe After Effects and Adobe Premiere Pro. This early video shows some skipped frames, which we are fixing right now. Taking the processing capability of the phone to its extreme unfortunately requires some amount of user feedback and field experience before we hit exactly the right balance between quality and speed for a given phone generation.
Shoot Your Own
Thalia Live HD/R works best on iPhone 6S and iPhone 6S Plus where it will deliver HD video (1080p, 30 fps) shot in true HDR (iPhone 6 will get 720p). Some older models are supported, but their cameras cannot shoot HDR and thus we can only tonemap an ordinary image on older models. Framerate and resolution are also reduced on older models.
Set your desired tonemapping settings. Thalia Live HD/R processes in real-time, so you can immediately observe how the image changes as you change parameters. For the somewhat overdone look people often associate with HDR photography, reduce global contrast and crank up local contrast, radius, gamma, and saturation. These settings will also bring out amazing detail in night scenes.
If so desired, you can postprocess the video you shot in pretty much any video editing software, from Apple’s iMovie on the iPhone to professional video editing software.
Amaze your friends!
How Does It Work?
The patent-pending HD/R technology in Thalia Live HD/R uses the iPhone’s camera to obtain HDR pictures for each video frame and works magic (technical term: tonemapping) to turn them into a video stream reflecting the scene’s dynamic range. The tonemapping is necessary because normal displays cannot show a very high dynamic range, so tonemapping will make the bright parts darker and the dark parts brighter while preserving or enhancing local contrast. The magic in our proprietary image-processing technology:
Extremely fast real-time processing allows 30 frames per second at 1080p resolution on iPhone 6S and iPhone 6S Plus. Consider that tonemapping a single photo on a powerful desktop computer could take minutes just a few years ago.
Virtually no ghosting and banding artifacts (‘ghosting’ and ‘banding’ are common problems with HDR processing)
Stores high-quality movies in Quicktime format in your phone’s camera roll
Full flexibility to change tonemapping parameters and see the result in real time: global contrast, local contrast, radius, noise reduction, gamma, and saturation. The exact meaning of these is somewhat involved, but if you just play with the sliders and explore, you will quickly get the hang of it.
