hmcindie Posted February 2, 2016 Share Posted February 2, 2016 Mjpeg codec is very inefficient.I hear this being paraded around. Yeah. It's "inefficient". But it's also great quality. If being an All-Intra codec makes it inefficient, then "Prores 4444 XQ" is also inefficient as it's bitrate is 500 Mbit/s for HD and 30fps Link to comment Share on other sites More sharing options...
MattH Posted February 2, 2016 Share Posted February 2, 2016 One issue with the crop is that you will have to use full frame lenses or third party aps-c. EF-S lenses will not work because of the mirror. I'm struggling to get exited about this, with the other options available at the same or cheaper prices.

I thought you could mount EF-S on FF but they will vignette? Link to comment Share on other sites More sharing options...
Phil A Posted February 2, 2016 Share Posted February 2, 2016 really why is that? I thought you could mount EF-S on FF but they will vignette?No, you can't mount original Canon EF-S lenses on a FullFrame Canon EOS camera, only 3rd party lenses.

It's also 12-bit, an industry standard, and flows like butter through editing systems. Whereas Canon are the only ones still using MJPEG, an ancient file format with none of those advantages.

tusoli5 Posted February 2, 2016 Share Posted February 2, 2016 Damn this looks promising! We are getting closer and closer to 10 bit or even raw. Mjpeg is very heavy but a really good looking and fun to work with codec, even in 8bit !This brings the competition to a tiny higher level in DSLR.I hope it won't cost more than a FS5...

Sergefrse Posted February 2, 2016 Share Posted February 2, 2016 I am not a 4K user at all.Do I notice right or did I miss something ? No 4:2:2 @ HD ??? I would have prefer HD Motion JPEG @ 4:2:2 more than a H.264 4:2:0 All-i/IB-P !!! HD M JPEG is less compression a must for secondary Color Correction & VFx.Do we need to shoot 4K to get a better HD quality Master ? I mean in term of compression artifacts and color depth. If yes, shame to manage more data than needed.Is HD mp4 or .mov also 8 bit rather than 10 bit ? High speed is a feature more important than 4K, I'd have preferred 125 fps for European "PAL" frame rate. Great! Dual AF best feature. canon.jp2 Link to comment Share on other sites More sharing options...
tugela Posted February 2, 2016 Share Posted February 2, 2016 Doesn't the mirror smash into the back of the glass?Why would it? I assume that because EF lenses work fine on crop cameras, the distances must be the same. Link to comment Share on other sites More sharing options...
sam Posted February 2, 2016 Share Posted February 2, 2016 "Doesn't the mirror smash into the back of the glass?"I lock it at about 30mm. Can probably get wider, but don't want to risk it. Obviously there are better lens choices, just wanted to note it's possible. Link to comment Share on other sites More sharing options...

Eno Posted February 3, 2016 Share Posted February 3, 2016 @Andrew Reid I told you should be more careful with technical details because sometimes mess up technical specs in your articles in favor of product or another and some people may judge you mind is clouded by fanboyism. It may not be this way but please prove me wrong in the future. Link to comment Share on other sites More sharing options...

Whereas Canon are the only ones still using MJPEG, an ancient file format with none of those advantages.An ancient and "inefficient" codec can look better with a huge bitrate than a new and more advanced one with a smaller bitrate.Case in point the 1DC. The 4k image blows all of the AVCHD and XAVCS image qualities of the A7 series out of the water, compression wise (no macroblocking, no compression artifacts from movement, grain remains and doesn't get smoothed out etc) Link to comment Share on other sites More sharing options...
