It occurs for example at scene changes. So it is one of the thresholds used to tweak the scene changes detection engine. Raising it will lower the number of blocks detected as changed. It may be useful for noisy or flickered video. The threshold is compared to the SAD (Sum of Absolute Differences, a value which says how bad the motion estimation was) value. For exactly identical blocks we have SAD=0. But real blocks are always different because of objects complex movement (zoom, rotation, deformation), discrete pixels sampling, and noise. Suppose we have two compared 8x8 blocks with every pixel different by 5. It this case SAD will be 8x8x5 = 320 (block will not detected as changed for thSCD1=400).

::{{Par2| |clip| }}
:::Input clip.
 
::{{Par2| |clip| }}
:::Vector clip from [[MVTools2/MAnalyse|MAnalyse]].
 
::{{Par2|scale|int|1}}
:::Allows to enlarge the motion vectors, in order for example to gain in accuracy (when {{Template:FuncDef|pel}} > 1 and {{Template:FuncDef|scale}} = 1, you can't see a variation of less than one pixel).
 
::{{Par2|sil|int|0}}
:::Allows to see a different level of analysis (when searching for motion vectors, a hierarchical analysis is done, and it may be interesting to see what happens at higher levels).
 
::{{Par2|tol|int|20000}}
:::Tolerance threshold. If the distortion induced by the motion vector is over var>{{Template:FuncDef|tol}} the vector isn't shown.
 
::{{Par2|showsad|bool|false}}
:::Allows to show the mean (scaled to block 8x8) SAD after compensating the picture and quantity ({{Template:FuncDef|ThSCD1}}) of bad ({{Template:FuncDef|ThSCD1}}) blocks.
:::Default is false which shows all vectors.
 
::{{Par2|number|int|-1}}
:::Allows to mark given block (with this number) as white.

:::It is ranged from 0 to 255, 0 meaning 0%, 255 meaning 100%. Default is 130 (which means 51%).
 
::{{Par2|isse|bool|true}}
:::Flag which allows to enable (if set to True) or disable (if set to False) ISSE, MMX and other CPU optimizations (for debugging).
:::Default is True. If your processor doesn't support CPU optimizations, it will be disabled anyway (and you won't be able to activate them).
