Hi Julius,
The only way to disable the video compression is when you insert the video and it does need to have a particular profile and encoding as detailed here.

Hi Ashley,
thank you verry much for your fast support :)
meanwhile the same video on the same slide chages randomly the "disablety" to bypass the Compression. I'm sure that all my videosetting are correct and im sure that the algorithm that check the videofile is a bit broken. Maybe you can tell me how that algorothm works, that would maybe help me to understand how i can fix this problem or you can give me a tip how i can bypass the 2nd encoding with e.g. manipulating a registry file or some kind of DIY fixing.
Hi Julius,
The algorithm is a proprietary code to compress the video files or to allow them to not be compressed based on those settings.
Prior to the option for disable the compression I know that an unsupported option, and I've seen this work with mixed results, would be to replace the videos in the published output with your higher-quality versions and our file names.
But please keep in mind, that's not something that is supported in any way by Articulate.

Hi Ashley,
thx for the tipp with replacing the files. finaly i find my mistake which disabled me the function to bypass the compression. I scaled the videos down a bit (28px in high) to have some place for the player controls. this trigged the compression. Now i change my videoresolution to crop these 28 px and have a resolution of 1920x1052 instead of 1920x1080. Furthermore my settings in Adobe Premiere are
Profil: Baseline
Level: 4,0
and i chose a vbr of 2Mbit/s and max 3 MBit/s and also a Keyframe(distance i think) of 24
aac audio with 44100 Hz Stereo with a bitrate of 128 KBit/s with an MP4 Multiplexer and the standard streamcompatibility.
in my case, these settings worked really well in Storyline.
I hope that this information will help.
Thanks Julius for that update and I'm glad it was something you were able to solve!

Hi,
sorry I was looking forward to early. :(
the problem is back, and I do not know why. I attached you an videofile of the problem (this was also exported with the same settings as i used for my storryline project, and its the german trenslated version of storryline but the steps are the same as in the english version i guess)
at first i load the videofile into the storyline, sometimes it works somtime the problem is in the first load in (change compression from automaticly to none). ok in this case it works perfectly. but if i wanna change the videofile (maybe the cutter make some changes and i need to repleace the video file) ok next i repleace it with the exactly same video file and now i can't change the the compression settings. next i delete it from the slide and load the same file again into it. now i can't change the settings. i try it ten times but this option will never come back. the only thing i can make is restart storyline and hopefully it work at first try. other i need torestart it for the 2nd time and so on. but i don't want to do this.
Hi Julius,
If you're making changes to the video and then replacing it - it sounds like it may not be the same video file and could have changed the compression elements and profile? If you'd like us to take a look at a video to help confirm we can certainly do that! Just send a copy of the video along to our team here.

Thanks Liath,
I've found an solution that works, but i can't use this in my specific case, cause it gives user the chance to easily download the videofiles. Im not shure that this solution works on all platforms and in the swf version. I didn't have access to the server that will host this project or the videos. Also it can't automaticly go to the next slide if the video ends. But otherwise it's a good solution for some Projects.
here the "solution"
You can insert a video as a web-object with the url of the video (you need the full absolute paths cause relative paths like ../folder/video.mp4 didn't work). This will use the internal HTML5 videoplayer of the browser und you also have a fullscreen button in the playercontrollers. You can also overlay some buttons in sl.
But i think Articulate need to fix this problem!

Hi Ashley,
In my example (bug_videocompression.mp4 ) I load a 100% Identical copy of the video file into Storyline just for testing. This triggered the error. I can reproduce this error anytime with all my videofiles. The encoding settings are allways the same. I created a encoding preset (.epr) for all the cutters on this project and checked these before rendering starts. The import works well sometimes (I have the option to select no compression) and broke after repleacing. Then i need to restart Storyline again. Im sure that is a Bug. I already send you a file that was encodet with these encoding presets. I'll send your team the video file and the .epr file that is an xml written text file of all my rendering settings.
Thanks for letting us know that you reached out to our support team (01074065) Julius. We can follow along as well.
Hi Julius! I popped in to take a look at your case and it looks like Wilbert is testing. I'll continue to follow along.
