We have a bunch of animations made with 0.5.4. Now we discovered 0.6.1.1 and are happy seeing the project alive. We tried to export videos from the animations made with 0.5.4 but simply pencil does nothing. Then we checked a new animation created with 0.6.1.1 from scratch exports as expected to mp4 and gif.
So, is there any compatibility problem with projects created with 0.5.4?
Using Fedora 26 and ffmpeg-3.3.7-1.fc26.x86_64.
Thanks in advance.
