Video compression option greyed out - did not edit in Storyline

Jan 20, 2020

Hi, 

The option for uncompressed video is greyed out. It is a separate MP4 I uploaded and haven't touched it with any Storyline editing tools as suggested in another article.

The video as-is is extremely blurry when imported into SL.

Not being able to control if the videos are compressed or not is tragic, having to redirect students onto different platforms to view videos due to the loss of quality is counterproductive, and takes away from a seamless learning experience.

This becomes extra problematic seeing as we're having to use more videos in our training to avoid whole chapters being just a powerpoint with more functionality.

I was having major issues with this , going way back , like 4 years ago.

Ever since Storyline 360 Update 75 (Build 3.75.30269.0), I have not had an issue where the option to turn off compression for a slide inserted video was grayed out. Are you still seeing this in the newest version of Storyline 360 ? 

I was glad I did not have the issues, as my last Storyline Project had 26 slides with videos (mp4s) for a total run time of 1hr and 22 min. Thankfully , I was able to leave all uncompressed at the slide level. 
I did find that when publishing for LMS, I prefer the " Static" video quality option ( set to 9) over the " Adaptive"

if you can set "Compression None", "Adaptive" has ALWAYS a reduced quality

e.g.

Static (original) .mp4

audio: 125 kb/s, 48 kHz, 2 channel AAC LC
video: 795 kb/s, 1920x1080, 25 FPS, AVC (Main@L4.1)

Adaptive .ts

stream_0: audio 22.05 kHz, 1 channel, AAC LC
stream_1: video 1920x1080 - 1441 kb/s
stream_2: video 1920x1080 - 855 kb/s
stream_3: video 1920x1080 - 501 kb/s

=> result:

  • doubled bandwidth with comparable video quality: 795 kb/s -> 1441 kb/s
  • audio quality reduction: stereo 20 Hz ... 24 kHz -> mono 20 hz .. 11 kHz

and publishing is very slow, because of 3 x (re)compression for the different video streams

and it's not compatible file:// (local playback)

and it's not compatible to some (?) LMS
