"Uh oh, unsupported video file"
Hi, so I've been using Adobe Creative Cloud Express (previously Spark) for a long time and all of a sudden it no longer accepts my video files when creating videos? I always work with .mp4 files and have never had any issues before. In most cases, these are files generated by Adobe Premier Pro. I have even tried using Adobe Media Encoder to convert them to alternatives, but still get the same error message.
Can someone advise if this is a known bug?
Thanks
Paul
