Alchemist File builds on our Emmy® award winning technology to bring you breath taking motion compensated image quality. Our algorithms benefit from more than two decades of research and experience into the exacting demands of format and framerate media transformation.
We understand the importance of being able to guarantee your deliverables, meet your client’s requirements and avoid having work rejected on the grounds of quality control. Being able to turn work around fast and minimize manual intervention enables you to keep your costs down.
Optimized to offer the very best image quality however complex the source
Alchemist File has been carefully optimized to offer the very best image quality however complex the source. Our solution also prevents the need for multiple transfers of the same assets by removing unnecessary conversion parameters.
Stunning pictures - first time, every time.
Alchemist File offers our latest intelligent adaptive de-interlacing to provide the sharpest pictures ever. Using a robust motion detector, our technology can intelligently soft switch the optimum de-interlacing mode on a pixel by pixel basis to ensure each pixel maintains the maximum possible resolution, even supporting HDR.
Multi-dimensional motion adaptive de-interlacing
Each de-interlacing mode has been carefully engineered to focus on a particular property of real images. These include static, vertical temporal and diagonal apertures of varying gradients. The use of soft switching avoids switching artefacts which can otherwise look more objectionable than the original interlace artefacts.
A motion estimator usually works on a local basis in the picture and measures not only the existence of motion but also its speed and direction. For framerate conversion the output of the motion compensation provide the required motion vectors for picture building.
The motion compensation used in Alchemist File has many major advances over our existing technology.
We have improved the phase correlation process to use multiple block sizes in parallel; this creates a greater range of candidate vectors, and means we don’t have to trade off performance between small, detailed objects whilst still handling a wide motion range.
Alchemist File allows the candidate motion vectors to vary slowly from pixel to pixel, using gradient based techniques to refine the vectors from initial constant values, this gives Alchemist File improved performance over its predecessors in areas such as zooms, rotations and perspective in a receding landscape.
The final step in motion estimation is to assign a motion vector to every pixel from the candidates, it’s imperative to get this process right. If it’s done incorrectly the vector field is noisy, small objects can be missed or behavior at motion boundaries is poor. We have developed a nonlinear filter that provides improved motion performance whilst maintaining the stability of our previous approach.
The picture builder is the final stage where the Alchemist XF creates new frames. It is at this stage that any problems resulting from inaccurate motion vectors, transparency, very complex motion and other transformations in the picture, may appear as annoying artefacts such as fractures. The new smooth picture building techniques eliminates the presence of such fractures.
Introducing Adaptive Cadence Technology: the ultimate tool for handling film originated and mixed cadence media.
Our intelligent cadence detection dynamically adapts the conversion aperture to deliver beautifully sharp and fluid moving pictures.
Safeguard your business and deliver content in the exact format your clients specify without the fear of costly rejections from customers.
