No Sync Video Filter

Rearranges the image by splitting it into regions and swapping their positions, producing a deliberate misalignment effect reminiscent of analog signal loss or desynchronization.
The filter does not distort geometry or color; it repositions rectangular regions of the frame.

No Sync is a spatial effect. It operates per frame and does not analyze motion or time.

With both parameters at 50.00%, the image is divided into four equal quadrants and swapped diagonally.

Parameters

Vertical (0.00 - 100.00%)

Controls the vertical split position of the image.

• 50.00%
  The frame is split evenly horizontally.
  The bottom quadrant swaps with the top.

• Below 50.00%
  The lower portion of the image becomes smaller.
  The split line moves downward, giving more vertical space to the top region.

• Above 50.00%
  The upper portion becomes smaller.
  The split line moves upward.

• 0.00% or 100.00%
  The image is not split.

Horizontal (0.00 - 100.00%)

Controls the horizontal split position of the image.

• 50.00%
  The frame is split evenly vertically, contributing to the four-quadrant swap.

• Below 50.00%
  The right portion of the image becomes larger.
  The split line moves left, giving more horizontal space to the right region.

• Above 50.00%
  The left portion becomes larger.
  The split line moves right.

• 0.00% or 100.00%
  The image is not split.

Keyframes

Both Vertical and Horizontal parameters can be keyframed.

This allows:

• Animated region swapping
• Progressive desynchronization effects
• Glitch-like transitions between layouts

Parameter interaction

• Vertical and Horizontal define the split positions along their respective axes.
• At 50.00% / 50.00%, the image is divided into four equal regions that swap diagonally.
• Moving either parameter away from 50.00% changes the relative size of the regions before they are swapped.
• Extreme values collapse the effect into a simple two-part swap along one axis.

Visual characteristics

• Hard rectangular splits
• Abrupt spatial jumps
• No blending or feathering between regions
• Clear, mechanical rearrangement of image areas
• Strongly reminiscent of video sync or signal errors

Recommended use cases

• Glitch and analog-error effects
• Stylized transitions
• Visual emphasis or disruption
• Abstract or experimental video design
• Simulating desynchronization without distortion or blur

Limitations

• No control over edge softness
• No rotation or scaling of regions
• Effect is purely positional
• Can be visually jarring on detailed footage
