Splice

std.Splice(vnode[]:all clips[, bint mismatch=0])

Returns a clip with all clips appended in the given order.

Splicing clips with different formats or dimensions is considered an error unless mismatch is true, or the first clip already varies in that property. Clips with different frame rates can always be spliced, the result then has a variable frame rate.

In Python, std.Splice can also be invoked using the addition operator.
