Question: Can I add my voice to a recorded video ?
Document: Recorded Xbox 360 and Xbox One video just fine until I happened to select TV on the Xbox One. At which it went into HDCP protection and stopped playing/recording any video through HDMI. Rest the device, Xbox One but never corrected. Avermedia's tech support didn't have a fix so I had to return the item. Don't do like I did and this is a much more user friendly video capture device to use than any other.
The included "editor" isn't very good but don't think it was designed to much more than trimming clips to size (at a cost of quality). Another sorta con is that it isn't very portable, however it wasn't really meant to be. Won't allow simultaneous streaming to twitch.tv or UStream.I recorded a little Grand Theft Auto Online gameplay with it so far, and have been impressed with its performance to date. This will not be a "cheap" solution, therefore it won't be for everyone.
UPDATE: 11/22/13This product DOES work with the Xbox One! Also just found out the 'watermark' that appears on the screen (when you watch your recorded items) can be modified to read whatever you want! :DTherefore, if you choose to post/publish videos you want to kind of 'copyright', this is perfect! You can change the location of it on the screen and everything!I am still learning about this packed little product and so far, so GREAT!
You have to remove the hard drive and plug it into your computer, very inconvenient. Also as many are reporting, almost every time you replace the hard drive back to the device, you get an error message saying the drive needs repairing. I tried 3 different hard drives, actually formatting a couple with the device itself, and still had these problems.I don't have the option of copying or transferring recorded footage between internal hard drive and usb drive.
This AverMedia is an amazing upgrade from it's predecessor. I had the AverMedia C281 for a year, it worked great but had some flaws, this however has seemed to fix all of the C281's problems and added a lot of great features. One thing I really enjoy about the C285 is that there is no pause when you switch to recording or stop recording. It also adds a microphone and headset hookup so you are able to record your voice while it's recording gameplay.
Why I like it so much... what is not to like! you want good quality audio/video and wanna run it PC free... Look No Further!!![... ]This also Contains Gameplay Footage on my channel, Tomb Raider, PVZ Garden Warfare, and More! !
I bought this because I read and saw videos that it worked with the XBOX ONE HDCP problem, but no, every time I hit the record button I got a message stating I couldn't record because the video is HDCP, it did it for both the XBOX ONE and XBOX 360 using the HDMI ports.
You see, this cards video quality isn't natively all that much worse than the better, more high end units. In fact, what makes the quality so bad is the fact that it is "PC free." There are indeed artifacting issues in games with heavy fog, clouds, smoke, or just high graphical fidelity, for which I blame Avermedia one hundred percent.
Really happy with this device. I used the first iteration of this device with  my 360 and always hated the fact I was unable to record my voice but loved everything else. For the second game capture had they added a mic plug in which allows you to record you and your friends in real time making for great game play videos with your friends. Quality of the recordings are great picks up the 60fps on Battlefield 4 (xbox one). All without using a PC which is not an option for me.
This device is very nice because of all the features it comes with! 1080p video recording looks great and gives you the option of either component or HDMI inputs, it can be controlled through their newly released app, and allows for storage directly to a hard drive. I would definitely recommend this to people who are planning on having their gaming setup stationary but not as much to people who are planning on moving theirs around because it's not nearly as small as their Game Capture Portable.
Answer: Yes, you can. Although I would recommend capturing your commentary with a separate microphone/recording device. This will separate the game's audio from your voice and give you much more freedom in the editing process if you're creating reviews. If you're just doing play-throughs however, and don't plan on editing or shifting dialogue clips around, this device has a port to record your commentary. You will still need a mic or headset of course.
