New filter version!

Project now is in beta-testing stage

Filter is used for video quality improving:

• HDR (High Dynamic Range) compression
• Shadowed colors and details restoring
• Light-struck colors and details restoring
• Faded colors restoring

Settings

New version improvements:

• Speed
• Interface usability
• Frame processing algorithm is switched to more efficient HDR frames rendering

Settings dialog allows to change:

• Frame illumination only
• Frame colors only
• Frame illumination and colors simultaneously

Correct illumination

1. Source image has very bright and very dark region - Processing image has HDR frames. Control using makes contrast low.
2. Brighten dark region - Allows to illuminate dark frame regions. Dark regions won’t be processed if control value is equal to zero.
3. Reduce bright region - Allows to restore light-struck frame regions. Light regions won’t be processed if control value is equal to zero.

Correct colors

1. Correct colors - Saturation setting control. If value is set in zero saturation won’t be changed. Note: recommended in use with Auto Levels.
2. Auto levels - Automatic levels correction. One reflects source frame illumination to all allowed illumination range.

Let’s consider job of the filter on a test rollers.
