Compress UV Animation
Updated: 4 Dec 2023
Compress a UV animation for export.
Compress UV Animation
Method #
This node is used to compress a two channel floating point image - for example a UV remap image loaded in a floating point HDR format - into a 3-channel RGB or 4-channel RGBA 8 bit per channel output, which may make it suitable for storing in a number of standard image or video codecs. The image can be decompressed using a Decompress UV Animation node.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active
Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Mode
Select how the uv animation is compressed - whether the result should use only the rgb channels of the output, or the alpha as well. using rgba provides higher quality but alpha may not be supported by all codecs and players.
Flip V
Flip the v axis of the animation when compressing.
Quantisation
The amount of quantisation applied to the incoming values. a higher level of quantisation may make the resultant image easier to compress and therefore smaller, at the cost of a loss of precision.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
