Video looks fuzzy
I have an mp4 file that we're using as a bookend for a course.
I attached the first one by Insert> video>from file (mp4)
I then copied that file in Storyline and dropped it onto the slide at the end - to form the bookend.
Same file, same format, same everything but the rendering/ encoding out is vastly different - please see attached images
Has SL rendered it out and that's why I'm getting these results?
If I use preview mode, it looks fine but when I come to publish the second image is what I see.
Any help would be mercifully accepted.
