Yeah you can record game sound + mic sound with MSi Afterburner, it is not supported out of the box you have to do a little work around. Easily found via google
Does it put both mic and game sound onto 1 single merged audio stream? If so that is no good to me
If you want the best, fully featured product which gives you 100% control use DxTory, it will do anything the other applications do if you want to configure it like that.
You can use _ANY CODEC YOU WANT_ (Choose something like Lagarith for low compression, low overhead but more space used or something like Xvid for high compression/less space but bigger overheads)
At any resolution - Be it crop or resize. None of this full or half size rubbish
Add as many audio streams as you want, from different sources and have them recorded as separate individual tracks
Best of all, once you decided on how you want it to work you can change it and set it for each individual game you play (a different profile for each individual game) That activates automatically when the process is detected. No more 100s of video tracks all bundled into the same root folder.
I'd like to record some Dayz footage, but I play with Eyefinity. So my resolution will be 5760x1080. Can any of the mentioned programs just record a fixed portion of my screen? Say 1920x1080, cutting off the sides?
Assuming Dxtory works with eyefinity, I assume it does. It will do it. Configure a resolution as a crop rather than resize.
Screenshot with relevant section boxed off:
Scale to 100% as normal. Tick Clipping, type in 1920x1080 as a clipsize with Horizontal/Vertical alignment set to Center and job done. Centre portion of the image is recorded.
