VirtualDub - [filters]

This is a list of currently available video filters for VirtualDub, in addition to the ones already built into the program.  You can load them either by clicking the Load... button under Video > Filters, or alternatively you can copy the .VDF files into PLUGINS\ under the VirtualDub program directory, which will cause them to be loaded at startup.

I cannot provide any warranty or take responsibility for filters written by third parties.  If you encounter stability or functionality problems, please contact the respective authors for assistance.

Deinterlacing filters

• Smart deinterlacer (Donald Graft) - Adaptive motion-based deinterlacer.
• Deinterlacer - area based (Gunnar Thalin) - Adaptive edge-based deinterlacer.
• PAL deinterlacer (Gunnar Thalin) - Field delay filter for PAL video.

• Unsharp mask (Donald Graft) - A better sharpen.
• Hue/Saturation/Intensity (Donald Graft) - Self-explanatory.
• Smart smoother (Donald Graft) - Adaptive smoothing filter.
• Dynamic noise reduction (Steven Don) - Thresholding difference algorithm for smoothing across frames.
• 2:1 vertical reduction (Chris LaRosa) - Faster way to halve the height of video.
• 2D cleaner (Jim Casaburi) - Adaptive spatial low-pass filter for removing noise while preserving detail.
• Temporal cleaner (Jim Casaburi) - Adaptive temporal filter to remove noise by comparing adjacent frames.

• Subtitler (Avery Lee) - Apply subtitles to video.
• Logo (Donald Graft) - Add your own bug!
• Colorize (Donald Graft) - Splash some color on black-and-white frames.

• Frame tweaker (Chris LaRosa) - Performs script operations to fade, fix, and correct your video.
• Antiflicker (Donald Graft) - Removes strobing flicker effects.

Description: Selectively removes interlacing artifacts based on a motion thresholding algorithm
Supports batch operation: Yes

This filter is an adaptive deinterlacer; it performs deinterlacing operations only when necessary, so that detailed, non-moving areas are not blurred.  It also supports shifting fields by one frame for correcting PAL video.

Description: Selectively removes interlacing artifacts based on an edge thresholding algorithm
Supports batch operation: No

This deinterlace filter works by detecting interlace edges within the same frame.

Description: Delays one field by one frame, to deinterlace PAL video.
Supports batch operation: No

Those of you who have encountered PAL video may be able to use this filter to remove field delay, restoring progressive frames.  It's not a general deinterlacer, however.

Homepage: http://www.oocities.org/Colosseum/Pressbox/8699/unsharp.html
Description: Performs a modified sharpening algorithm on the image
Supports batch operation: untested

A clone of the infamous Photoshop "Unsharp mask" filter.

Homepage: http://www.oocities.org/Colosseum/Pressbox/8699/hue.html
Description: Applies color and tonal adjustments to the video
Supports batch operation: untested

Allows correction for slight color shifts in video; for instance, changing brightness without affecting saturation like the levels filter does.

Description: Attempts to remove noise from an image without blurring.
Supports batch operation: untested

Useful for cleaning up video.

Description: Attempts to remove noise in an image without blurring.
Supports batch operation: No

Use this filter to reduce noise in video.  It works by thresholding the image against the previous frame, and selectively accumulating or freezing low-activity areas.  The algorithm for this filter has been integrated into VirtualDub as a fast capture filter.

Homepage: http://www.oocities.org/cplarosa/video/
Description: Fast height-halving filter using non-overlapping 1x2 kernel.
Supports batch operation: Yes

This filter is similar to doing a 2:1 vertical reduce with the resize filter, except that the filtering kernel does not overlap; this makes the 2:1 vertical reduction filter faster.  As LaRosa points out, this filter can be used for simple deinterlacing as well.

Description: Adaptive noise reduction filter using a 3x3 blur.
Supports batch operation: Yes

This filter reduces noise similarly to Steven Don's dynamic noise reduction filter, but this one works spatially instead of temporally.  Useful for cleaning up video.

Description: Adaptive noise reduction filter.
Supports batch operation: Yes

Another video filter that reduces noise by thresholding across frames.

Description: Applies Sub Station Alpha v2.x/4.x scripts to video.
Supports batch operation: Yes
Updated: (V1.3b) Fixes multi-line wordwrap hang problem.

Pretty self-explanatory; handles most of the common features in SSA scripts.  It has text antialiasing, so your subtitles look good at small sizes.

Homepage: http://www.oocities.org/Colosseum/Pressbox/8699/logo.html
Description: Overlays bitmaps on top of video frames
Supports batch operation: Yes

Use this to attach your own personal trademark to video.

Homepage: http://www.oocities.org/Colosseum/Pressbox/8699/colorize.html
Description: Adds color
Supports batch operation: Yes

I think the name says enough.

Homepage: http://www.oocities.org/cplarosa/video/
Description: Simple script-based frame editing operations.
Supports batch operation: Yes

This filter allows you to run a script on your video to mask selected frames, fade in/out, replicate, etc.  Useful for correcting specific flaws in video.  Due to VirtualDub filter API restrictions, however, this filter cannot move frames backward or change frame count.

Description: Removes strobing effects from video
Supports batch operation: Yes

This filter is able to remove strobing effects, such as from a videotaped film projection.  Very impressive!
