eMotion Engines DigiCrank is a high-quality motion compensated technology applied to Resolution independent (4K/2K/HD/SD) recranking product. This technology allows multiple high-quality frames to be generated from every incoming frame in the required resolution.
The product utilises global motion estimation in combination with a pixel resolution motion algorithm to provide high quality slow motion and standards conversions. The technology will allow multiple high quality frames to be generated from every incoming frame. This application of the technology enables Cinematographers to vary the fixed frames rate after acquisition.
Key Features Include
- Slow Motion Processor - Variable frame rate conversion
- Utilises advanced motion estimation technology
- File based processing
- DPX/Cineon RGB
- Resolution independent 4K/2K/HD/SD
- Pan, scan and re-size
- Auto shot detection
- Re-Timing - speed up, slow down, stretch and shrink
Figure 1 shows the basic operation of the machine. DigiCrank receives video file and then applies high quality motion compensation techniques to increase the number of frames in the output file. Image files as clips are imported for processing. Motion estimation is applied and the user selects operations to be performed. Shot detection may be performed as the clips are imported. All operations will be performed across shot boundaries.
In addition to frame rate conversions, DigiCrank will pan, scan and re-size the image.
Image file import can be defined by simple scripts or a user friendly graphical user interface (GUI). The GUI will allow the user to select the output frame structure by either of the following methods:-
Output frame rate = input frame rate multiplied by X
Or
Fix output time slot and vary frames to suit
Market:
DigiCrank is currently aimed at standards conversion and video retiming applications for digital film, high end commercials and music videos:
- Short form work – creating 25 frame master copy for the European market and 30 frame copy for the US market
- Retiming applications for the VFX market
- Editing short form – such as music videos, commercials and documentaries
- Restoration – retiming to cut unusable frames
