5.2k 1x3 is about 3k 1x1 to my eyes.

for 700d/650d/eosm/100d, 5.2k 1x3 2.40:1 24p is about 3.75 MB/frame x 24 frame/s x 1.4 x 0.7 = 90 MB/s, with the lexar silver card, this mode may be continuous. this is s35 full frame for these crop mood cameras, the live view is high res color mode even in crop modes, practically very useful.

another useful mode on 5d3ml is 3.5k 1x1 mode, it can do 16:9, most importantly, it is s35 so that many cinema lenses are adaptable to this mode. 7MBx24x1.4x0.7 ia sbout 170 MB/s, so if do 10 bit, 3.5k 1x1 16:9 is continuous, maybe 12 bit will work.

dual iso is possible in this uhd 1x1 mode on 5d3 ml, can increase 2-3 stops, at the expense of possible moire and alias in the highlight area. i watched uhd 1x1 dual iso travel footage, i did not see the moire and alias,, or they were not eye catching. the practical problem is the striped monitoring when using dual iso.

5d3 ml in 1x1 uhd mode can only have 2:40:1 and larger aspect ratio, so each frame is 6 MB, so 6 x 24 x 0.7 = 100 MB/s. for 12 bit, 6x24x0.7x1.2= 120 MB/s, for 14 bit, 6x24x0.7x1.4=140 MB/s. so UHD 1x1 24p 2.40:1 14 bit lj92 lossless may be continuous if using fast cards, card spanning, sd card overclocking. so 5d3ml is still relevant. and it is 4k 14 bit, crop ratio 1.3 to 1.4 in uhd 1x1 mode.

with global draw off, 5d3 ml can do uhd 2.40:1 24p 10 bit color depth lj92 lossless ml raw continuously, 8 MB / frame x 24 frames / s x 0.7 (lj92 lossless compression least compression coefficiency) = 140 MB/s < 145 MB/s. maybe 12 bit too in some cases.

some cards like lexar silver can do 100 MB/s, stably at 80 MB/s, this is better than cf card. this makes 650d/700/deosm/100d better than r1mx in terms of data stream writing speed. 5d3 ml has 145 mMB/s, about the same as epic-x, maybe a little less, not much. so 14 bit color depth is more possible with many modes. also, 200d may have a 15-bit mode, the highest in all video camera, including alexa.

i still remember that viral video clip taken by gh1 bragging that it can match red one. i personally went the canon and later ml road. i bought 2 brand new g3, hacked one, but sent as gifts. i liked em5's color and ibis.

" Doug JensenApril 27th, 2011 04:55 AM Re: Upcoming hands-on comparison of F3, FS100 and AF100 from Philip Bloom Having used a pre-production FS100 myself, I can agree with most of Phil's impressions of the camera. However, he says " . . . HDMI and it is only 8 bit 422 . . ." I have no way of testing it myself, but I'm pretty sure that is incorrect. I have been told personally by Juan Martinez at Sony USA that the HDMI output is 8-bit 4:4:4. And if you don't have a recorder that can handle 4:4:4, then the camera will automatically send 4:2:2. At least that is what I have been told by the man who should know." FS100 can do hdmi out 8 bit 4:4:4. I have not tried myself yet. I only use hdmi for a monitor.

are they outdated? which one do you prefer? pros and cons

varicam 27h has 60p, 3 ccd thus global shutter no debayering, dps from 2000-2010 like its footage and see it as a substitute of 35mm film rolls. maybe ccd performs better even with a relative fast reading sensor?

when i pan with c300 og, the 50mbps mpeg codec makes the whole scene blur. i cannot see anything clearly. once the panning stops, suddenly the image is very clear. i just hate it. i use nanoflash's top codec 280 mbps mpeg and 30p and it is cured. when using ml raw cameras, i see clear images during slow panning (fast panning shows rolling shutter) at 24p. i almost always use 24p for ml raw cams to save bandwidth.

probably 50d has a really slow reading sensor. i know fs100 can do 60p easily so the sensor may be faster.

i think that andrew has a very good insight. maybe the r1mx, the eosm, gh1, do not have a fast reading sensor, so that more optimized (actually limited by the then technology) for 24p motion blur.
