Yes, this is the author’s exclusive right; according to Art. 10 para. 2 (c) CopA authors may make their work perceptible and available in such a way that people may access it at any time and from any place. This can also be done by uploading files (in this case, the video or the photo). At the same time, this is also an act of reproduction pursuant to Art. 10 para. 2 (a) CopA, because the video or photo is usually also saved on a server. The author is also permitted to do this.
