I have a LaTeX Beamer presentation that I output into a PDF slide show. I want to turn into a video file (with the ability to add sound later) so that I can generate animations from Beamer . How can one do this? I've tried importing the PDF to iMovie, but the quality of the frames drops dramatically.

  • What are the contents of the PDF? Do you have access to the original material used to create the PDF? – Michael Liebman Apr 9 '18 at 19:56
  • @MichaelLiebman The PDF file was made in the LaTeX document class Beamer. I have the .tex file from which the slides come from. My goal is to use Beamer for frame-by-frame animations. – user1337 Apr 10 '18 at 2:36

Convert the presentation to a series of image files. The classic image format for that is a TARGA sequence. But you can use any format that your LaTeX tool chain can output and a video generator can import. For generating the image sequence, there are several vector and raster formats that LaTeX can export. You can then use ffmpeg to turn the image sequence into video.

As a reminder, be sure to set the aspect ratio of your presentation appropriately.

You could convert the PDF file to PNGs (use density 144 for double the size):

convert -density 72 in.pdf out-%04d.jpg

Then import the images in any decent video editor, add a sound track, fine tune the result and export/render the video.
