Thermal in REC: questions
How do I get the Thermal look on iPhone video?
Open REC, pick Thermal from the camera strip and press record. The look runs live in the viewfinder at 9 frames per second, so what you frame is what you get. You can also import a video you already shot and develop it through Thermal.
Does the Thermal camera change the sound?
Yes. An instrument's afterthought of a microphone: mono, 200 Hz to 5.5 kHz.
Is Thermal free in REC?
Every camera, Thermal included, is in the free download, and your first take is free. Unlimited takes need REC Pro ($9.99 a year or $2.99 a week, US prices).
