Compression on MP4 inserted into Storyline
I am trying to publish a course with an inserted MP4. When I choose 'None' for compression the zip file is over 1,000 MB (our LMS max is 750 MB). When I choose 'Automatic' for compression the zip file is only 77 MB. The issue is that the compressed video is too blurry, compared to the video with no compression. There is such a large discrepancy between the two file sizes. Is there away to compress the video just a little bit, so I get it under the 750 threshold? I have tried to use the publish quality settings but have not found a successful result with these settings.
Hey Sara
In your publish quality settiings, I would recommend Static over adaptive and experiment with adjusting the video quality settings to get the quality and size you desire.
I ran 2 quick tests this morning. One using the Adaptive setting and the other just switching to statice and keeping the quality in the mid-range.
The Adaptive was over 3xs bigger than the static. I Could not tell any difference in viewing quality.
Thanks for the tip. I'm using static and the file is still over 1,000 MB.
Compression 'None' means storyline will copy the original imported video without recompress into the zip
if you do not use this setting, Storyline always adjusts the video to the dimensions of the slide.
e.g. slide 960x 540, video 1920x1080
- Compression 'None' -> video 1920 x 1080
- Compression 'Automatic' -> video 960 x 540 + the video settings (-> publish settings)
best practice for size/quality: compress the video outside storyline to the final data size and use 'None' + 'Static'
Thanks for this info. It's good to know how much compression happens with Storyline's automatic setting. I think I need to compress more before putting in Storyline. I'm using Premiere Pro but having trouble getting a smaller size there without video degradation.
how long (in minutes) are the videos in your course together?
1hour and 25 minutes.
a video with 1.25 h (in HD) is typical much bigger than 1,000 MByte
there are two options
- lower the dimensions and/or the quality of the videos (while Premiere export)
- use vimeo or another video platform (-> video from website)*
*hint: trigger in storyline don't work with external video
Just to clarify, the Storyline zip file is 1,000 MB. Our LMS limit is 750 MB. The MP4 files I've insert is much larger.
