WinX HD Video Converter Deluxe by Digiarty Software  is a Video conversion tool for Windows and Mac OS, which allows the conversion between various video formats, almost all popular formats out there. The interface is simple and very user friendly, it also support multi-core video conversion to speed up things. Interface has been kept simple with less options probably keeping noob users in mind.
You start by selecting the file you want to convert. I tested it out with a .vob file which I wanted to convert to avi. The options have been kept to a minimum to keep it simple and won’t overwhelm a new user with plethora of options.
As soon as I chose the file, I was presented with a dialogue box to select the frame rate, this menu should have been for PAL and NTSC, which is more obvious to most people (NTSC corresponds to 29.97 frame rate and the other one is for PAL). I went ahead and chose 29.97 since I was using a NTSC video file. They might want to fix it in the next version.
Next I made the choice for output type (.avi) in this case and chose the codec (choices are XviD and DivX). I used the default Video quality and size. Changed audio type to orig (which I presumed to be ac3 5.1 surround sound which identical to original VOB file). I also changed number of processors to 3, to speed up things.
The encoding process started and got over in reasonable time (30-40 minutes). There is no control over the output file size, the file created was of 970 MB, which was of reasonable size for the quality which was quite good.
But to my surprise the audio codec for the output file was not ac3 but mpga. So the software doesn’t support ac3, which might not be a big deal for most common folks, but would have been nice to have it.
The power of this software lies more on converting various video formats to media formats compatible with portable media players like iPod, iPhone, Zune, PSP etc. So if you are looking for a simple and user friendly media converter to convert your media collection for portable media formats, you might like to give WinX HD Video Converter a try. If you want something or more serious encoding with lots of options to tweak the final output, you might want to give this a pass.
