I don't know the bitrate differences that Storyline is publishing to when you change the published output quality settings - but if you're looking to keep the video at the same settings as when you inserted it - have you looked at how SL2 allows for you to publish without compressing the MP4?
I asked around regarding the bitrate, and Storyline uses a proprietary algorithm where it takes into account the video file and then it determines the compression to apply and how it should be encoded, including what elements you change within the publish quality setting. You can see more information here on how Storyline 1 handles compression, and there is an unsupported method here to replace the published output with the original video file.
I feel like I'm getting the run around though, the link you've offered me does not speak towards video bitrate unfortunately. Additionally, I'm not looking to replace the published file.
Can you tell me if adjusting the video quality slider has any impact on:
Bitrate of the video as it's encoded (I assume with the h264 codec as an MP4).
What is being adjusted with the slider? (Ie, small file = 150 mpbs bitrate, higher quality = 500 mbps
Yes, the bit rate is the video property that will change as you adjust the video quality slider. The pixel dimensions of the video will not change.
However, there is no fixed bit rate associated with each of the numeric stops on the video quality slider. With the video quality slider set at 9 for example, I have seen videos that publish at over 2000kbps and other videos that publish at under 300kbps. It's really all about the quality of the video that you bring into Storyline 1, and how our algorithm decides it can best optimize the video.
As Ashley's link mentions, we worked hard to optimize video compression in Storyline 1 so you'd get the highest possible quality at the lowest possible file size. When inserting a movie, we recommend using a high quality video. Then, let Storyline 1 take it from there.
Please let us know if you need anything else, and have a great day!

Ideally, I want to know what the slider is actually doing in the Video options.
Hi Jason,
I don't know the bitrate differences that Storyline is publishing to when you change the published output quality settings - but if you're looking to keep the video at the same settings as when you inserted it - have you looked at how SL2 allows for you to publish without compressing the MP4?
Who would know that information?
It must have a purpose correct? What does adjusting the slider actually do for video content?
I am interested in finding out this information for Storyline 1.
