Body: <p>I have a problem I am struggling for 2 days. Maybe someone can give me some light.
  I made a huge keynote presentation (100 slides), with videos and animations. I expected to have one small exported video for each slide.  It seemed a good idea at first, but now I see I cannot export each slide separated automatically. So I tried to export all slides with the same timing in Keynote and then split in equal parts using ffmpeg, but keynote does not export the video with exact timing between slides. Then I advanced a little and tried to detect scene changes using ffmpeg (which I did and got a list of timestamps), but when splitting with ffmpeg the keyframeimage is never on the first frame making the videos unusable. Now I was searching for a solution using Mac automate, but it seems it does not have the right Keynote functions... I know that doing it manually would work, but exporting in keynote is slow and it would take hours, and maybe I will have to edit all the slides and export again. I have most of the professional video tools (final cut pro and adobe premiere/after effects.  </p>

Comments.Text: To the OP, can you just load the Keynote video in a video editor and then note down the slide turnover times? You can then use those times to split the video using ffmpeg in a single command.

Comments.Text: @Mulvya that's seems possible at first, but there are 2 problems. First to note the slide turnover times would be manual. Second, when ffmpeg split the video, the key frame is never in the beginning, so the video starts black until the first keyframe is reached. If I ask ffmpeg to follow keyframes, it simply ignores the exact timing of the cuts and waits for the next keyframe.

Comments.Text: My reasoning here to use keynote is simply that it is far more easier to add a logo and subtitles and keeping it consistent through videos than other video producing tool. That's why I haven't used Final cut or Premiere to create the videos, I tried, but spent triple time for each video.

Comments.Text: Your question is not really clear, but there is an option to export a keynote presentation as a .m4v file. If you then want to add more wait time in between the slides, you can add freeze frames in FCPX or Adobe Premeire.
