Tips: Increase resolution
Enhance Video Resolution
Enhancing video to a higher resolution is always a tricky business. The problem is that the software has to figure out what are the true values of those pixels that do not exist in the low resolution video. An interpolation of any kinds will only produce blurry result.
Topaz Enhance has a filter, Double Resolution*, that tries to solve the problem based on so-called “super-resolution” theory. The basic idea is simple, by using multiple frames of the original video, the software have a better chance of figuring out the non-existing pixels and therefore create a high resolution video.
DV to HD (720p)
Two issues related to converting DV to 720p. First, DV videos are usually interlaced, so you need to properly de-interlace it. You can use the tips and example in De-interlace video to first convert the footage to 1440x960 progressive video.
Then you need to fit the resulting video into the 16:9 aspect ratio of 1280x720. You can simply use After Effects transform to pan and scale it. Since it is generally scale down, you don't lose quality.
DVD to HD (720p)
DVD may have two different types of video contents. One type is created from a video source, which is interlaced. Another type is created from film, which uses 3:2 pull-down for NTSC and 2:2 pull-down for PAL/SECAM.
For DVD with interlaced video, it is the same as converting DV to HD as disbribed above.
For DVD with film material, here is the key. For NTSC, you need to first convert the footage to 24 FPS, or 23.98 FPS, by either using After Effects or other utilities. This is very important. Remember the Double Resolution filter only works well on video with smooth motion. Without converting to 24 FPS, the film’s true frame rate, the filter will not have correct motion information to perform well.
How about 1080i/1080p?
You can try to apply the Double Resolution* filter twice, but it takes quite a long time to process. Alternatively, you can simply scale the 720p up using transform.
Low Resolution Video to SD
Most digital cameras nowadays can capture small video clips, e.g., at 320x240. If you have to use one in your project, you may try to enhance them into 480p first using Topaz Enhance.

- View the footage at 200% or high zoom. If the footage has obvious blockiness and fringes due to codec, use the filter Remove Compression Artifacts*. Be careful not to set the suppression value too high. Some remaining artifacts can be removed later. But if you suppressed useful details, you will not be able to recover it.
- Use the Double resolution filter to double its resolution.
- You tryDenoise & Enhance* to further suppress noise and enhance details.
