Since the appearance of fast processors, especially the ones with multiple cores, a task of video encoding / decoding has slowly entered the mainstream of computer usage. Digital video cameras are now recording to hard disks and increasingly flash memory, while digital photo cameras are now appearing with high-definition recording support (720p at this stage).These, and other sources of video files are coming in a variety of recorded video formats. A product that could read and write to these video formats was needed to fill the void. Hence VisualHub was born on Apple's shareware market.
VisualHub allows users to drag-and-drop video file(s) that they want to convert to another format. Number of formats on offer are numerous - MPEG formats, iPod and Apple TV formats, DivX, Flash, Microsoft WMV, even conversion to formats that can be read by certain game consoles are available. Although all these formats come with presets, user has the option to modify a number of settings.
Some of the most usefull advanced settings are the ability to limit the file size, enable deinterlace option and select Two Pass conversion process for a better quality. There are also options to choose a video and audio decoder, audio frequency etc.
High definition .MKV files have also been successfully converted for playback on Apple TV with highest setting. Results are quite good, while rendering speed is acceptable.
On author's website, there is a good support forum, where fixes and solutions can be found. Also, visitors can post suggestions for new features, and most of them actually get included in point upgrades.
Overall, for any Mac user that required video conversion, VisualHub is a must have.
