FlipVideo

What is it?

The FlipVideo node flips your video horizontally, vertically, or both directions. This creates a mirror effect that can be useful for correcting orientation or creating artistic effects.

When would I use it?

Use the FlipVideo node when:

  • You need to correct video that was recorded upside down or backwards
  • You want to create mirror effects for artistic purposes
  • You need to flip footage to match other video clips
  • You're creating content that requires flipped orientation
  • You want to create symmetrical video effects
  • You need to correct camera orientation issues

How to use it

Basic Setup

  1. Add a FlipVideo node to your workflow
  2. Connect a video source to the "video" input
  3. Choose the flip direction (horizontal, vertical, or both)
  4. Run the workflow to flip the video

Parameters

  • video: The video content to flip (supports VideoArtifact and VideoUrlArtifact)

  • direction: Flip direction (default: "horizontal")

    • "horizontal" = flip left to right (mirror effect)
    • "vertical" = flip top to bottom (upside down)
    • "both" = flip both horizontally and vertically

  • processing_speed: Balance between processing speed and output quality (default: "balanced")

    • fast: Fastest processing, lower quality (ultrafast preset, CRF 30)
    • balanced: Good balance of speed and quality (medium preset, CRF 23)
    • quality: Highest quality, slower processing (slow preset, CRF 18)

Outputs

  • video: The flipped video, available as output to connect to other nodes

Example

Imagine you want to create a mirror effect on a video:

  1. Add a FlipVideo node to your workflow
  2. Connect the video output from a LoadVideo node to the FlipVideo's "video" input
  3. Set "direction" to "horizontal" to create a mirror effect
  4. Run the workflow - the video will be flipped horizontally
  5. The output filename will be {original_filename}_flipped_horizontal.{format}

Important Notes

  • The FlipVideo node uses FFmpeg with high-quality flip processing
  • Horizontal flip creates a mirror effect (left becomes right)
  • Vertical flip turns the video upside down
  • Both directions flip the video in both axes
  • The original audio track is preserved
  • Processing time depends on video length and resolution
  • Logs are available for debugging processing issues

Direction Recommendations

  • For mirror effects: Use "horizontal" - creates left-to-right mirror
  • For upside down correction: Use "vertical" - flips top to bottom
  • For complete rotation: Use "both" - flips in both directions
  • For camera correction: Use appropriate direction based on how the camera was oriented

Common Issues

  • Processing Timeout: Large videos may take longer to process; the node has a 5-minute timeout
  • Wrong Direction: Make sure you've selected the correct flip direction for your needs
  • No Video Input: Make sure a video source is connected to the "video" input
  • FFmpeg Errors: Check the logs parameter for detailed error information if processing fails
