Ideas for a better (user-friendlier) PDF export e.g. with stills from the video

[ralferlebach]

At the moment, the PDF export produces quite fine results. However, in term of user and learner friendly exports, it would be much better to embed the video content into the export instead of the time frames of the subtitles.

What I have in mind are PDFs with stills from the video (let's say in intervals of 30 seconds - which may a subject to the settings) on the left and its cues within this interval to its right, each on an new line.

Furthermore, the gaps should be adapting to the word lenght of the deleted words. (What I am using is 2 underbars each letter plus 2 additional underbars. So, "This is a [hidden word] in a text" would become "This is a (11 letters x 2 + 2 = 24 underbars) in a text"). Also, this could (or should) be subject to settings as for some applications, there might be no hint on the word lenght intended, on others it would be adviceable.
