Converting SD footage shot at lower quality into higher definition projects is now few clicks away, thanks to the Super Resolution plugin for After Effects and Premier Pro by Infognition.
With Super Resolution plugin, you can upscale digital videos and images to any resolution with superb quality: be it 480p to 720p, 720p to 1080p, 480p to 1080p or anything else.
The method used for video upscaling actively employs motion estimation and high frequency image data fusion, producing a clear and sharp result. Infognition Super Resolution is capable of upscaling videos to any desired resolution.
How Super Resolution Plugin Works
The plugin obtains information from a number of neighbor frames to upsize each current frame.
The algorithm analyzes and accumulates information, thus the more sequential frames are processed while upscaling, the higher quality you finally get.
When first applied to a layer, Infognition Super Resolution takes just a few frames preceding the current one.
For more flexibility, video can be processed in 2 quality modes:
- High speed SR
- High quality SR.
These modes differ in speed and resulting quality.
The best quality is obtained in High quality SR.
You’ll see them work only when “Resolution / Down Sample Factor” is set to “Full”.
In other modes (used for quick rendering in low resolution) the plugin will use simpler intra-frame rescaling method.
Let’s consider a real example of upsizing video 4 times with super resolution algorithm.
The same frames zoomed 4 times:
Step 1. Upsize all frames 2 times using good quality interpolation, in this case Lanczos3 method:
Step 2. Using sub-pixel accurate motion compensation, find similar areas in neighbor frames and intelligently merge frames to combine information (and in some cases reduce noise):
Now we have our video upsized 2 times using super-resolution.
We repeat this process to get 4x enlargement.
Step 3. Spatial interpolation again:
Finally, Step 4. Combine neighbor frames to get more details using motion compensation:
Now let’s compare it with what we originally had:
Quite amazing, isn’t it? But it’s no magic, only a bit of math.
Current version of Infognition Super Resolution plugin was tested in After Effects CS5 and CC 2015 as well as Premiere Pro CC 2015, and should work in other Win64 versions of After Effects and Premiere Pro.
