Alparysoft Deinterlace filter

Alparysoft Deinterlace filter is a lightweight video codec package which can be run on all Windows versions in order to help you apply the deinterlacing process to interlaced videos.
Interlaced videos embed two frame rates for consuming as little bandwidth as possible. In order to be displayed accurately and correctly, the two sub-fields taken in sequence need to be combined in a single frame. The deinterlacing effect tries to solve this particular problem by disabling the visual defects.

Installation process

Alparysoft Deinterlace filter can be deployed on your system in no time. You are only required to press a few next buttons in order to finish its installation. In addition, you are given the freedom to select the saving directory. A restart is required in order to apply the new changes to your system.

Configuration settings

The application provides support for several setup parameters that allow you to tweak the deinterlacing process in detail.
You are offered the possibility to pick the deinterlacing method, namely only even rows (for doubling the fields) or simple interpolation (cubic interpolation of the luma component), or disable the effect with a single click.
Advanced features allow you to opt for area-based interpolation or motion estimation, replace only interlaced pixels, as well as provide details about the interlace detection threshold, search area, blocking distance threshold, and replacement threshold.
You may resize items and lock the output size, reset the current settings to the default ones, set motions parameters to a slow of fast rate, show output window, as well as automatically apply the deinterlacing filter to all files.

Bottom line

All things considered, Alparysoft Deinterlace filter comes with several handy features for helping you eliminate blurred and stripped images in video files.
On the downside, the configuration panel is not quite intuitive, there’s no support for a help manual (only tooltips are displayed when you hover your mouse cursor over certain functions), and the utility hasn’t been updated for a long time so it may cause compatibility issues especially on newer operating systems.
