If you want to use this as a YouTube! gallery on your site, the free version will work... It's buggy, but it'll work.

If you more than that, look elsewhere. The code is heavy and extremely buggy. FFMPEG integration in the "pro" version is nothing but a fairy tale. Check the mfg's forum - there are multiple complaints concerning FFMPEG, and I've not found a post from any user that claims they have FFMPEG conversion working with this product. It's a fallacy.

Support is virtually nil, so is running on J1.5.

Payment/verification system is flawed at best. These guys put way too much energy in making sure they get the user's money, and not nearly enough in product development.
