I stumbled on to Road Movie because Subler, essentially a great little free program was creating unreable video files. I got tired of troubleshooting it. Then found Road Movie.
I've been very happy with it.
Before Road Movie I was using 3 different applications in my workflow to convert, add meta data and add chapters. Now I'm down to one app and can do it in batches.
I use it with and without the Turb.264 HD depending on what I need to do and it works well. Speed, even on my previous generation Core Duo 2.0ghz Mac Mini with 2GB ram is very good.
The site/company is also very supportive, responding to questions quickly and with helpful answers.
For a novice it seems very easy to use.
For someone with more experience it has enough flexibility to be a very useful part of the video workflow toolkit.
$25 is extremely reasonable for everything you get.
