If you wonder why the Skype Cloud Recording only records 8 frames per seconds, worry not, you are not the only one having this issue. In fact this change has been done globally for all users using Skype. Due to the pandemic, the amount of users signing up to Skype has risen a load and the server load skyrocketed. In order to balance out this load, the recording functionality has reduced the 15 fps to 8 fps temporarily until March 2021.
The team who made this decision didn’t bother to tell tech support department about it, hence nobody knew about it when I contacted tech support about this first.
I went through all support levels until I have reached T3 which just called me this morning, to inform me about the situation.
Also somebody started a thread about it on reddit, this is how I knew I am not the only one affected.
There will be an article about it on the Skype Blog informing all users about this shortly.
