The 9mbps of the NEX-3 may be sufficient, if the codec is really well engineered, but given the other choices it seems sony wants the MP4 to be the "lower quality mode" and so I'm guessing they just artificially hampered the camera. So, why isn't there a 24fps mode for those who want it? No good reason. Lord knows in europe its probably going to be doing 25fps.
But if the hardware can do 30 fps, it can certainly do 24fps. I'm sure they are constrained with bandwith and can't record 60fps. They made the right choices in so many areas with these cameras, I'm surprised to see artificial limits on the video mode.Īnd don't get me started on recording 30fps only. This kind of consumer unfriendly attitude is what is hurting sony overall right now. Ether they're spending that extra CPU time making for much more efficient encoding (which I doubt) or they are just artificially lowering quality to protect other products. Instead they limit it to 9mbps? Why is this? We know the CPU can encode 1080 at 30 fps, so 720, which is about a quarter as difficult to encode can certainly be done. I don't mind if Sony wants to limited this camera to 720p - and putting it in MP4 format is what has me interested in these cameras in the first place (otherwise I'd get a GH1 which I've been considering for a long time- only I hate AVCHD.) On the NEX-3, presumably you have a camera that has the same CPU and sensor as the NEX-5, so there's no reason it couldn't also shoot 1080. (EG: To protect your camcorder market, but their consumer cams shoot AVCHD anyway as well.)
Again, another artificial hampering of the MP4 version to reduce quality, making AVCHD not look as crappy as it really is.Īnd interlaced? There is no reason in the world to record interlaced unless your goal is to make video a hassle for your users. The only possible reason is to artificially attempt to make AVCHD- an outdated, poorly thought out and obsolete format- look better.Īnd 1440x1080? This made sense years ago when Sony couldn't manufacture sensors that were 1920x1080, or didn't have the horsepower to encode 1920x1080. So why is the straight MP4 format reduced to 12Mbps? In order to make an AVCHD stream of 17MBPS the camera has to produce 17Mbps MP4. And so I read the specs, and discover there's not a single usable** video mode.ġ280x720p first off, there is no reason in the world to produce interlaced video.
