What do you like best?
I bought Screenium a few years ago as part of updating my classroom material. It was fairly cheap and did what it is supposed to do: capture movie to show what you do on screen.
Good basic feature set: full screen, dedicated screen section or follow cursor. Recording is smooth and quick.
Price is fine and the software works intuitively. There are occasional updates, but overall, the product seems stable and mature.
The concept of a media folder from which you can control all capture is OK, but not as scaleable in the end. I had to remove most capture (or transfer them to a backup) as they took too much storage space and cluttered the interface.
What do you dislike?
While the recording is fine, it is a quite linear, one-way process. There is little to no control over the result afterwards and you always have quite a lengthy conversion process. It also had problems recording Windows applications running from Parallels.
Mac OSX only and was not usable to capture some of the Windows-applications I wanted to record.
While the product seemed quite stable, it did not get many updates nor many new features.
Recommendations to others considering the product
While I started with Screenium initially, it did not full fill my needs completely. I migrated to ScreenFlow which has more extensive control over the output, as it has a complete Non-linear video editing workflow.
What business problems are you solving with the product? What benefits have you realized?
I did use it a few times in the past, but have migrated to ScreenFlow which is more complete.
