AV Video Converter can help you watch your videos on different devices by converting them between formats. Likewise, it allows downloading video YouTube clips and extracting audio from video. The tool supports a wide array of formats, including AVI, MPEG, WMV, DivX, MP4, H.264/AVC, AVCHD, MKV, RM, MOV, XviD, and 3GP.
Luckily, when downloading video, you do not need to know the real video URL, as the program can strip it from the YouTube link you provide. Similarly, it is not necessary to wait until the current job finishes to start the next because this tool can process various of them simultaneously.
The great news is that setting the target conversion parameters is not a traumatic decision with this program. Fortunately, there are various ready-made profiles you can use, and some are conveniently identified with the names of the supporting playback devices. Again, it supports converting files in batches; yet, it is not allowed to convert the files on the list to different profiles in the same session.
All in all, AV Video Converter is probably the easiest video converter available thanks to its wizard-like interface. However, it lacks some of the features you can find in other advanced converters, like the ability to import DVD video and make some basic changes (trimming, merging, cropping, etc.). The product is shareware and allows a limited number of free tries.
