Here's how Articulate Storyline encodes videos in your courses, based on their original file format and the output options you choose when publishing:

Original Video Format Flash Output Mobile Output HTML5 Output
MP4 Re-encoded to MP4 Re-encoded to MP4 Re-encoded to MP4
FLV (no alpha channel) Encoded to MP4 Encoded to MP4 Encoded to MP4
FLV (with alpha channel) No change (FLV) No change (FLV) Encoded to MP4*
SWF No change (SWF) Not supported Not supported
All other file types Encoded to MP4 Encoded to MP4 Encoded to MP4

*Alpha channel transparency isn't supported in HTML5 output. As a result, FLV videos with alpha channels will be encoded as MP4 videos in HTML5 output.
