Bruno Posted October 15, 2012 Share Posted October 15, 2012 [quote name='sanveer' timestamp='1349721639' post='19493'] Where did you get all these figures from? Please post the url. thanks [/quote] The Magic Lantern guys have been investigating codec improvements and higher bitrates, and that's the figures they've discovered. That's the capture resolution, and then the footage is upscaled to 1080p. That also explains why HDMI out is lower resolution.

see ya Posted October 15, 2012 Share Posted October 15, 2012 [quote name='Bruno' timestamp='1349703707' post='19483'] 600 lines seems to be an exaggeration. The 5D3's video capture resolution is 1904x1072, vs 1720x974 for the 5D2/7D/550D. [/quote] And personally from the visual comparison between T2i 4:2:2 raw silentpic in non record operation (1056x704) versus the 4:2:2 raw silent pic at 1720x974 that we get whilst recording, I feel the latter is softer suggesting an upscale of 1056x704, although A1ex suggests otherwise, he's to know I guess. But long time back I remember Canon suggesting they added video recording functionality by rerouting the liveview feed from the LCD and added a h264 encoder chip to the hardware of the 5D MK whatever.

nigelbb Posted October 18, 2012 Share Posted October 18, 2012 According to a1ex who should know what is fed to the H.264 encode is 1720x974 (550D) and 1904x1072 (5D3). Quote Link to comment Share on other sites More sharing options...

[/quote] I am not sure the figures are accurate. Also, upscaling and dealing with line skipping must be cause some lines to mysterious appear, or dissapear. Since the Mark III doesn't apparently have any line skipping (or much lesser), so the resolution would be a more. Actually, I remember reading that the Mark II resolves around 590 lines, and that the Mark III adds another 200-250 lines, at least. I'll have to search for the sources, cause I read it a while ago. Anyways, I guess, I should go look. :angry: Quote Link to comment Share on other sites More sharing options...
Bruno Posted October 18, 2012 Share Posted October 18, 2012 The guys are in there, playing with the codec and trying to improve it, I guess they should know their resolutions by now. sanveer 1 Quote Link to comment Share on other sites More sharing options...

[/quote] Apparently a lot of people are playing with the codec and files. All of them have different versions, of what the resolutions of these various cameras are. I merely stated, what seemed like the most agreed upon resolution. It reminds of some famous quote, I read, as a kid, about 2 reasonable men, coming to different conclusions, about the same thing, and both being right ... :P Quote Link to comment Share on other sites More sharing options...
