copy mov files back to JB Device possible ? I want to use Splice

[keevill]

Is there any way I can get mov files created on my iphone 4s back into my iphone or my ipad 2 in order to use Splice to join them ? ( I deleted them some time ago and have them on my flash drive )
Both devices are JB and running 5.1.1
I can use Ifunbox but Splice cannot see them.
Thx,
