Nifty little tool for creating cleanplates from busy shots.

FrameMedian is a temporal median toolset that calcualtes a median from a range of frames. Unlike the TemporalMedian tool that samples 3 frames, the FrameMedian can sample up to 20 frames.

What is it for?

The tool is generally used for creating cleanplates from super very bussy shots. Like in this example plate must be stabelized before using






The Tool


 The tool have 2 calculation methods. One is where you define a frame range and a number of samples. This causes FrameMedian to automatically pick frames evenly distributed across the framerange.

The other is the Specified Frames method, where you can pick the frames you want to sample yourself, giving you much greater control.


  • More samples is not always better, so try difrent frame ranges and sample counts.
  • If you get artifacting try to remove the frames that have garbage in the problematic area, or add multiple frames where the area is clean.
  • Try to avoid using frames where the lighting on the background plate is changing, like light flicker or timelapses
  • If you want to clean timelapses split it up into sections and clean a fraction of the plate at a time.
  • The more stable the plate is, the better the result will be.
  • In most cases you will get a better result if you denoise the plate before using the tool.

Very nice improvement over frame blending.

So when I use this I am getting an expression error with a list out of range. In my case, at TO_4

When i investigated, it looks like all the nodes from TO_1 to TO_4 are using a slightly different expression than the others to get the frame number, and it fails sometimes. If I replaced the expressions on those with the expression from TO_5 then they work fine.

However I have a question. IN the group, it has 20 frame holds to do the median. They all seem to be active. And indeed when the group comes in, in is pulling frame numbers from outside the range specified.

This seems... wrong.
