It turns out that Adobe uses their “Preserve Details” resampler in not just Photoshop, but also in their After Effects video editing software. That means that with TRUPIX, TMM is competing with a well-established company that has been producing and selling the technology for years and has already dominated the video upscaling market.

Adobe’s resampler is also fast. In their demonstration videos and tutorials, the effect occurs as soon as the user clicks OK to proceed. It is also fast enough to be shown in a live preview area of the resampler’s user interface. It also offers noise reduction.

There has been some conjucture that any slowness in TRUPIX is due to the need to write processed video frames back to permanent storage such as a hard drive. However, there is no indication of this. The site’s chart ambigiously says “Processing Time Result” only and clearly defines the test platform as having 16 GB of RAM and a 1 TB SSD drive. Given that Windows uses write caching, and SSD drives are very fast, it is reasonable to assume that TRUPIX is not a realtime upscaler. If it is, then surely this would be a feature point that the company would have mentioned. We either have a slow product or poor marketing.

The minimum system specifications are odd. RAM is not mentioned, but apparently a 1 TB SSD drive is required. Does TRUPIX require some sort of massive disk-based database in order to work?

Another concern mentioned is if TRUPIX is not based on fractals. After all, much was claimed of fractal’s superiority over other methods. The processing speed suggests that fractals have been abandoned as the requisite block searching is extremely slow. At the very least, the company owes it to its shareholders to explain whether fractals are used or not, and if not, why not. It is possible that TRUPIX is some variation on NEDI (new edge-directed interpolation). Since NEDI is well documented and can be implemented by anyone, the market for TRUPIX is even more questionable.

Finally, it would be nice to see non-zoomed, high-resolution versions of their test images, so that TRUPIX upscaling could be compared to actual high-resolution content.
