First they had the Zoom Q3which combined a pretty good pocket digital audio recorder with a Standard Video (640 x 480) recorder. Now they've gone and added 1080 recording and called it the Q3HD.
With Video resolution of 720p at 30 or 60 fps or 1080p at 30 fps, and Audio formats: 44.1/48/96kHz 16/24-bit WAV (PCM) or AAC up to 320kbps, would you do better getting this instead of the more traditional Zoom H4n Handy Portable Digital Recorder?
Well despite my concerns about the H4n sometimes messing up recordings, I'd still probably get that over the Q3HD simply because the H4n has XLR jacks. Much better for adding external mics. Still, never underestimate the value of good sound; unfortunately, often that means getting closer to the source, rather than getting a better digital audio recorder...
The Q3HD is expected before the end of the year at $299.
