Some loading indication would be nice

It appears that the program is not providing sufficient feedback during its execution, leading to a perception of inactivity. Specifically, when I input a command with a URL list and press enter, the program freezes. This also occurs after the table is generated, presumably during the data fetching process.

It would be beneficial to incorporate informative messages that detail the current operation, helping users understand what the program is doing. Additionally, providing feedback when a video processing task is completed and the system is moving on to the next one could enhance the overall user experience.

(the table looks different first time, other sequence of columns)
