A few days ago I posted here two Xvid files, which demonstrated that the progressive 30p video produced by HF100 can be converted to 60p without loss of spatial resolution. At the end, all the strobing and jerkiness inherent to 24p/30p video is gone. Some people couldn't watch the 60p clip because of not enough of CPU power. You can have better luck with these files converted to H.264 (many video cards support H.264 HD video at hardware level):http://www.physics.mcmaster.ca/~syam/00014.mp4http://www.physics.mcmaster.ca/~syam/00014_4.mp4
The first clip is 30p (very close to the original 30p footage from HF100), the second one is 60p. They are 50-70 MB each.
I've done quite a lot of research regarding which video mode to use on HF100 - 30p or 60i. It now looks to me that both modes have issues. Making both modes look good (i.e., converting them to 60p) requires sophisticated software or hardware, and the results are never perfect - fast moving objects will produce artifacts. Unlike true 30p-60p conversion (now present only in the most expensive AV equipment), the 60i-60p conversion (deinterlacing) is present in all AV equipment, albeit with a wide range of quality. E.g., my Blu Ray player BDP1200 has a very good quality deinterlacing chip (HQV Reon), which cannot do true (motion compensated) frame rate conversion. The only real advantage of 30p is being twice more sensitive (less noise). An important advantage of 60i is that it's very straightforward to convert it to good quality DVD video (e.g. to send to relatives overseas), as no time interpolation is required, only downscaling the spatial resolution of individual, interlaced fields.
I bought HF100 mainly because of this new feature, 30p video, but unfortunately it's ill suited for home video. where you often cannot control your panning speed - resulting in bad strobing when watched on modern AV equipment. I believe in a couple of years we will see first consumer true 60p HD camcorders, which will be the ultimate solution to the above dilemma (30p vs 60i) - no interlacing artifacts of 60i, and no jerkiness and strobing of 30p. For now, sticking to 60i seems to be the best option.
BTW, true 1080/60p camcorders already exist, but they are not cheap (150,000$): http://www.sony.co.uk/biz/view/ShowP...egory=HDseries
