Does anyone know how I can convert M2TS files into a usable file able to be uploaded to a website? I have the free download version of Prism and wonder if I should purchase the Plus version. Also, how can I convert VOB files to files that can be uploaded to a website? Both of these files (VOB and M2TS) will not convert with the free version. Also, which file should I convert these to? Once I am able to convert of course. Any advice is appreciated. Thanks.
