# Input file requirements for video rotation
<a name="auto-rotate-requirements"></a>

You can use rotation for inputs that have the following video characteristics:
+ Progressive video
+ Chroma subsampling scheme 4:2:2 or 4:2:0

In addition to the general input restrictions for the rotate feature, to use *automatic* rotation your input file must conform to these limitations:
+ Input container: .mov or .mp4
+ Rotation metadata specifying 90, 180, or 270-degree rotation

  If your rotation metadata is within one degree less or more than the values listed here, the service will round to a supported value.

**Note**  
If your input file has rotation metadata that specifies a rotation other than those listed here, the service defaults to no rotation.
