Swaps chroma channels in YUV clips.
Contents |
SwapUV(clip clip)
- Swaps U and V (chroma) channels. Corrects certain decoding errors – faces blue instead of red, etc.
UToY(clip clip)
VToY(clip clip)
- Copies U or V chroma plane to the Y luma plane.
- All color (chroma) information is removed, so the image is now greyscale.
- Depending on the color format, the image resolution can be changed – i.e.,
- with a YV24 source, UToY is the same width and height as clip, but
- with a YV12 source, UToY is half clip's width and height.
UToY8(clip clip)
VToY8(clip clip)
- Shorthand for UToY.ConvertToY8 and VToY.ConvertToY8, but faster.
YToUV(clip clipU, clip clipV [, clip clipY [, clip clipA ] ] )
- Copies the Y (luma channel) of clipU to the U channel of the output clip and the Y (luma channel) of clipV to the V channel of the output clip.
- If clipY is given, copies the Y (luma channel) of clipY to the Y channel of the output clip.
- AVS+ And if clipA is given too, copies the Y (luma channel) of clipA to the A channel of the output clip.
- Depending on the color format, the image resolution can be changed.
[edit] See Also
- Show RGB channels with ShowAlpha/Red/Green/Blue.
- AVS+ Extract for Deep Color support.
[edit] Examples
- Blur the U chroma channel
video = ColorBars(512, 512).ConvertToYV12 u_chroma = UToY(video).Blur(1.5) YToUV(u_chroma, video.VToY) MergeLuma(video)
- Show U and V channels stacked for illustration purposes.

[edit] Changes
| v2.60 | Added UToY8, VToY8. |
| v2.60 | Added new color formats Y8, YV411, YV16 and YV24. |
