Zoom Q3HD review
Some quirks I’ve picked up…recording file size max is 3.5-ish GB, so at highest resolution (1080p/30fps) & sound quality (PCM 96kHz/24-bits), that’s about 35 minutes. The recording auto-splits at this max file size point, which created, for me, some interesting problems when I recorded a Messiah concert in which I was singing – it looked like it was recording straight through (the little red light could be seen from the stage), but when I reviewed the concert, there were clips in the middle of some numbers. I have also been unable to successfully upload the concert files to YouTube at this highest quality recording. I can hear sound on my computer, via QuickTime, iTunes, and the Handyshare 2.0 application that comes with the camera. I am, unfortunately, unable to hear any audio once the file is uploaded to YouTube (example here). This is a HUGE disappointment. The other qualities I have uploaded work fine, just not this highest quality. I think this is a YouTube issue that will hopefully be resolved, as the files play fine on my computer.
For use in the studio for voice lessons, I use a resolution of 720p/30fps, with AAC compression at 192kbps (high-quality, but compressed). This works well, and hour music lessons record with no shortage of time. A 4GB SDHD card (which are currently about $10 on amazon.com) has approximately 1 hr 21 min of recording, as was the case with my original Zoom Q3. [···]
