Believable slow motion video samples on Youtube for phones and cameras are so confusing nowadays that you simply cannot rely on them unless it comes from a reputable source. The avalanche of fakes is so big that it makes it next to impossible to find the real ones out there. It also makes it extremely hard to choose a slow motion capable phone when the supposed videos you are looking at are faked from other devices or even professional slow motion cameras.
There is also the big problem of stealing real quality slow motion footage from other channels and using it in compilations that claim to be from a phone or camera in order to get clicks and views for quick revenue. The problem goes even deeper when these fakes overtake most other real videos due to the viral nature of their compilations as they usually look much better than anything these cheap devices they claim to represent can do. We examine a few cases that can educate you on how to spot these fakes!
The Nubia Red Magic 3 phone is something of a hyper-customized piece of gear for the performance-oriented gamer with crazy high-quality 3D specs and even fan cooling inside the case which is a first for a phone and a testament to the engineering to get it to fit in such a slim case. The specs that really caught our attention are that the phone does 8k video recording and 480fps 1080p with a beta mode to bring that all the way up to 1920fps.
We had no indication that the 1920fps mode is indeed real for a few days until we found out it is actually an option on the phone and not a typo which many including us thought up as 1920pixels for 1080p not frames. But yes it is frames which makes it confusing but in our estimation also allows for decoding the truth behind this spec and if it is actually all that it claims to be.
There has been a lot of work put it developing software that can interpolate frames for video editing and compositing applications. Twixtor in the late 90’s was perhaps the first time the technology could make something worthwhile and really produce acceptable results in a computationally acceptable timeframe.
Today the most used algorithm is Adobe’s Optical Flow in Premiere or Time Warp in After Effects which use vector directional plus acceleration of pixel values to derive in between frame data to generate new frame information from the preceding frame as point A and the next frame as point B. The results can do some wonders to really slow down things above the frame rate ceiling of the camera.
