Just tested 650D's crop new v2 modules preset 1736x2214 1x3, with AR 2.67, the resolution is 1736x1954. It is 10-bit, 14-bit lossless, 24 fps. This preset uses the super35/aps-c full width. The benchmark for this mode is 60 MB/s for 128 GB below Sandisk Extreme Pro 170 MB/s sd cards. For a 256 GB below Sandisk Extreme Pro 170 MB/s sd card, the nominal benchmark is 45 MB/s, actually it can be continuous as long as the data flow is below 60 MB/s.
For a relative complex scene with some trees full of green leaves at ISO 100, the data flow is about 65 MB/s. 650D can record in this mode for 150 frames, that is more than 5 seconds, enough for typical uses. For extreme cases, a scene with some trees full of green leaves at ISO 1600, the data flow is peaked at 70-75 MB/s, 650D can record 70-80 frames, about 3 seconds. As long as it is 3 to 5 seconds, human eyes accept this as a movie.
If the benchmark in this mode can be optimized to 65 MB/s like what is in the UHD 1x3 preset, or even improved to 75-80 MB/s like in 70D, this mode can be robustly continuous, good for long takes like interviews.
650D's crop new v2 modules preset 1736x2214 1x3, AR 2.67, 1736x1954, 10-bit, 14-bit lossless, 24 fps, super35/aps-c full width, is 5.2k anamorphic 1x3. Its IQ is equal to 4k raw 1x1 cameras, at least with a high compression ratio of 12. I would rate 650D as a super 35mm 4k raw camera.
I did some field shots with AR 3, 1736x2214 1x3, 1736x1954, 10-bit, 14-bit lossless, 24 fps, super35/aps-c full width. It was continuous at ISO 100 for a typical street scene. The data flow was about 55-60 MB/s. The IQ is even better than the UHD 1x3 in full screen mode. The IQ is very cinematic like. AR 3 is actually very cinematic, although not conventional.
For pp, I used MLV App latest version. Although it is not recommended, I used MLV App's sharpening at 30-50 for 1x3 footage. The sharpness is good enough. I have not noticed artifacts in full screen mode. When it is over 70 in sharpening, the artifacts are noticeable. So MLV App is fine for me to do the whole pp, before I do editing in Blender's video editor. There is no need for DaVinci Resolve, unless high end cc is required.
Thanks theBilalFakhouri for his great work.
