I could download almost all the videos that I wanted, just two points to consider:

- Some videos that I tried to save with lower quality were saved in .ts format, and the video was not downloaded correctly (so maybe the script to convert the videos can be improved).
- Usability in general is a bit confusing. I felt that the app could be more simple.

Aside from that, it worked really great for the videos I needed to download in the original quality. Thank you!
