What I look for in a video converter is that it handles a lot of formats, is simple to use and converts quickly. VisualHub achieves all of these.
Whether you're looking to convert to iPod, PSP, DVD or any other format, VisualHub will offer the presets you need. Converting is also very easy and simply a case of dragging and dropping your file, selecting the correct setting, and letting the program do the hard work. VisualHub also includes a number of advanced settings to improve the quality of your videos and handle elements like framerate, bitrate, width and height. You can batch process files for quicker conversions.
VisualHub is also very good for fitting videos onto DVD, up to 18 hours it claims, but you'll have to check that the video quality is good. The program features a preview window to make sure conversion was successful.
The major drawback is the volatile audio quality when it comes down to conversion. You might need a few tries before you get a video with proper image and audio quality. Also, it's a bit of a surprise that VisualHub doesn't feature subtitle support.
VisualHub makes converting videos easy and quick and is a great program to prepare a DVD. It only lacks subtitle support and better audio conversion.
