- Scaling/Pixel Interpolation: Re-size, or scale an image or video to a larger resolution to further identify suspects.

- Sharpening: Enhances the edge contrast of an image or video.

- Stabilization: This is most common today with smart phone video evidence. It reduces the amount of movement from the user that created the video evidence.

- Frame Averaging: Increase the quality of the image by combining data from surrounding frames as well as a better signal to noise ratio in your images or videos.

- Speed Reduction: Decrease the original playback of video evidence to view the events as they occurred in more detail.
