I'm currently considering buying Bandicam, but I'm also on the fence about another game recorder - which I will not mention here, out of respect to Bandisoft.
Now the issue I'm seeing with Bandicam, is that although the codec support is broader, an the file sizes are smaller (which is awesome), the GUI is ugly as hell and it has tutorials written all over it, whereby if you click them, it opens a web page. This is not very professional looking and is not exactly an ideal thing to have posted all over a product. I'd also like to highlight that for folks less knowledgable about the names of codecs, I'd recommend you put lossless next to some of the uncompressed formats so as not surprise people by eradicating their hard disk space.
Another thing with Bandicam which I'm not fond of, is the lack of Multi-Channel audio support. I'm currently using a Stereo headset over 6 channels via a Xonar DG, an it gives me the surround I need (without using that awful Dolby Surround feature) but Bandicam obviously doesn't let me record multiple channels. This isn't a huge deal breaker considering Youtube doesn't support multi-channel audio anyway, an even though I don't record often, I don't want to find myself having to purchase ANOTHER piece of recording software 3 years down the line, which is what I'm doing now because Fraps seems to have died, doesn't support Windows 8.1 desktop recording (due to a lack of dwm.exe) an file sizes are still inexcusably huge.
So, basically, will the User Interface for Bandicam ever improve, or will we still see this Windows 98 looking window with advertisement-style links to tutorials all over it?
Peace.
