I do not want a free one because they all loose video quality so what is the best paid one, price does not matter.
What format(s) are you trying to convert? (MKV to AVI for example)
I use Pazera Free MP4 to AVI Converter Its actually really good... I mean you convert other stuff other than MP4 and AVI its really good obviously its free. Idk what the quality loss it though.
Leawo video converter works great for converting my fraps uncompressed files to .mp4, but I only use the free version. This program offers quite the variety of media file types.
I have used Media Espresso, because of their support for GPUs. But the downside is that they have limited support for the file formats. There are alot of other converters that do have this capability though but be sure to pick the right one; do some research and find yours.
you can use this one for free, I think there is a paid for version GPU and AVX support worked great for me with no quality loss
it was actually one of the first post in this forum topic back on RTW
Very powerfull encodeing softwhere for free http://sourceforge.net/projects/megui/
Any format you can think of (allso supports GPU rendering/encoding with Nvidia video cards)
There are a million tutorials online to show you how to use it.
"I do not want a free one because they all loose video quality so what is the best paid one, price does not matter." That's Pretty Damn Funny, Considering how completely untrue that is. Granted there are crap Free & Paid converters, Doesn't matter if its "paid" or "free" If you don't use the proper settings, Video codec/ Audio codec/ Bitrate/Container/ Aspect ratio/ etc, etc. Then it will lose quality.
Handles everything i've thrown at it, And its Free / Open-Source.
