Compressed video in storyline is 3X larger in SCORM zip
If you publish with Adaptive video quality, Storyline publishes multiple versions of the video at different sizes, typically high, medium, and low quality plus streaming segments and playlist files. The published package may therefore contain several encoded copies of the same video. The size shown in View > Media Library represents the imported project asset. It does not necessarily represent the total size of all versions Storyline generates during publishing. Have you tried switching the publish quality to Static?
But the ability to turn it off is greyed out and otherwise seems to be set to Automatic.
This can happen when the video has been modified inside Storyline’s built-in video editor for example, cropped, trimmed, or otherwise adjusted. Once Storyline processes the file internally, the Compression: None option may no longer be available.
Another possible cause is an unsupported H.264 profile. For example, if the video was compressed in HandBrake, reopen the encoded file in HandBrake and check the Video tab. This should show the video encoder, codec profile, and related encoding settings.
Storyline generally supports standard H264 profiles such as bbaseline, main, and high for pass-through publishing. If the file uses a less common profile, such as high 444, high422, or another profile, Storyline may be unable to use the original stream without re-encoding it. In that case, the Compression setting remains locked to Automatic or appears greyed out. Example of unsupportet format and the Compression option disabled or greyed out.
You can download the MediaInfo app and open the videos in question to view more detailed information about their codec, profile, bit depth, frame rate, and other encoding properties. Alternatively, upload the videos here, and I can check the encoding details for you.
