However, I can't see them with any viewer, help please
This likely means that they were already damaged prior to recovery; keep in mind that Recuva cannot repair files, it can only recover them exactly as written on the drive. (The 'Condition' is simply an estimate - in this case, it means that Recuva couldn't detect any damage, but not necessarily that there isn't any.)
You might be able to use a service like: https://fix.video/ or the software in this article: https://www.makeuseof.com/tag/how-to-repair-broken-avi-files-that-wont-play-windows-only/ to repair the file(s).
