A99 Soft Video Note~

i've mentioned this before, and i don't know if this has been mentioned by anyone else here recently, but i am quite certain the problem is caused by the line skipping technique used to downsample the 24mp image off the sensor to the 2mp video frame. that is pretty much the end of the story, and it has nothing to do with settings or lenses or faulty cameras or avchd compression, and can't be fixed by firmware updates. the a99 exhibits similar video quality problems (softness, moire, aliasing) that the 5d mk2 has, which famously line skips (moire problem exacerbated due to line skipping combined with the olpf). the 5d mk3, while still relatively soft, doesn't have moire and aliasing problems because it no longer line skips and instead has a 3x3 pixel binning technique (allegedly). the gh2 doesn't line skip (exact technique unknown, but supposed to be some combination of intelligent pixel sampling to a 4 mp image followed by downscale to 2mp) and exhibits far less problems with moire and aliasing, and has arguably the most detailed video of any of the dslr style cameras.
