Hey Storyline, stop transcoding my MP4 videos, please.
Jun 23, 2017
Hey there -
I am creating a series of eLearning Storyline modules that contain long video clips that I have encoded meticulously to get acceptable quality with the lowest bitrate possible. However, I notice that when I publish my Storyline courses, it transcodes my MP4 files to BIGGER files. For example, one source video is 17MB and when transcoded by Storyline, the output MP4 balloons to 25MB.
Is there any way to get Storyline to NOT transcode the MP4 file and just leave it as is? If not, I may have to re-encode the original videos into a higher quality source format to avoid the "garbage in, garbage out" problem from transcoding one lossy format to another.
Alternately, can I get away with simply replacing the published .mp4 video in the "story_content" directory with a renamed copy of the source video? I prefer to not do that, as it's going to add a lot of grunt work to do this with every publish of every module.
You would think Storyline would be smart enough to know when a piece of media is in a "compatible" format already and not re-encode it.
