Video problems
Jun 08, 2012
Size problem:
I have set the story size to 720x405 px (16:9).
When I insert a mp4 video with size 1920x1080 px (16:9) from file, the screen isn't completely filled because Storyline is re-encoding the video to 718x405 px.
Quality problem:
When I preview or publish the project the video stutters.
The quality of the re-encoded video in the story_content folder is adequate, but when I run the story.html file the video stutters. The Video quality slider is set to best quality when I publish.
So my question is: Why does this happen? Is there anything I can do about it?

Hi Tomas,
Do you have a copy of the source video file that I can use for testing?
I am having the same problem. I understand this is might be a square-pixel vs. non-square pixel issue perhaps? Regardless is there a solution? We have done so many test on our end rendering out new videos and nothing is working.
Thanks,
Tarah
Forgot to post a reply. I have been busy producing e-learning courses
By now I have been using hundreds of videos in Storyline, so here is an update of the video problems:
Size problem:
It doesn't matter if I use a 720p, 1080p, flv or mp4 or any other video with the ratio 16:9 in Storyline. With the story size set to 720x405 px (16:9), Storyline will re-encode the video to 718x405 px when I insert it. The solution I have been using is to resize the video in Storyline to 720x406 pixels so it fills the screen. I haven't seen any big quality losses with that. It's not a big deal.
Here is a link to a 720p mp4 source video file.
Quality problem:
This is my biggest issue with Storyline. It compresses video to much during re-encoding!
Especially the audio of the video. My clients can barely accept the quality loss.
The solution I have been using is to use a video format that Storyline doesn't re-encode.
By the way. It's the same then I insert audio from a file. Storyline compresses it to much.
Here is a link to a 16 bit 44KHz PCM WAV source audio file
Bandwidth is not a problem today. Let us please have an option in Storyline to use the source files without re-encoding, or encoding them to a higher quality!
