Canon R5 Exterior 8K ProRes RAW Dynamic Vary Lab Check – 8K With out Overheating



Taken with a fast dynamic vary check of the brand new Canon EOS R5 8K exterior ProRes RAW recording mode of the Canon R5 utilizing an Atomos Ninja V+? And as a bonus, outcomes for the brand new Canon Log 3 mode are thrown into this text as properly. So please sit down and skim on …This isn’t one in all our typical lab exams because the Canon EOS R5 has already acquired our prolonged lab check remedy, which you’ll learn up on right here. Again then inside 12 bit Canon 8K RAW in addition to inside 10 bit 8K Canon Log (H265) recording was already potential.In the mean time, firmware updates have introduced Canon Log 3 to the Canon R5 in addition to exterior 8K ProRes RAW recording through HDMI utilizing the brand new Atomos Ninja V+. Sufficient causes to shortly retest the dynamic vary with these new choices.Dynamic vary of exterior ProRes RAW 8K recordingIn case you aren’t conversant in how we check dynamic vary of cameras, take a look right here.A fast phrase on dealing with the 12bit 8K ProRes RAW recordsdata in postproduction: on an 8K timeline in PremierePro our NVIDIA GeForce RTX3090 graphics card which is on mortgage from NVIDIA (thanks) had no points dealing with the recordsdata, GPU reminiscence hovered round 10-12 GB, the load round 16%. As quickly as you begin to add noise discount, reminiscence utilization and cargo begin to skyrocket – which is to be anticipated. Primarily because of the GPU reminiscence, I like to recommend the RTX3090 card should you plan to complete in 8K.The Canon EOS R5 linked to the Atomos Ninja V+. Picture credit score: CineDPlugging the Canon EOS R5 through HDMI into the Atomos Ninja V+, the digicam is straight away acknowledged. Curiously sufficient, Canon Log 2 is displayed because the Gamma – we are going to use that later in PremierePro to carry RAW right into a log house for additional evaluation.Digital camera info as displayed by the Atomos Ninja V+. Picture credit score: CineDOn the digicam itself, the bottom ISO worth that may be chosen is ISO800 if the output is about to “HDMI RAW”. That is attention-grabbing, as the interior RAW recording has ISO400 because the lowest ISO. ISO400 can also be the bottom ISO worth for inside H265 Canon Log recording. For Canon Log 3 the minimal ISO worth jumps as much as 800.To date so good. Growing the ProRes RAW recordsdata on an 8224×4336 (17:9) timeline in PremierePro utilizing Canon Log 2 because the gamma curve yields the next waveform plot:8K ProRes RAW on an 8K timeline – the waveform plot of our Xyla 21 chart. Picture credit score: CineDAbout 12 stops may be recognized above the noise flooring and a touch of a thirteenth cease inside. As may be seen from the waveform, decrease stops (i.e. shadows) are very very noisy. Curiously, inside 8K RAW recording (at ISO400) is displaying much less noise, see our lab check right here.IMATEST confirms this end result, very excessive ranges of noise are calculated for the decrease stops (displayed within the lowest of the three graphs under). Therefore, the dynamic vary reads solely 10.4 stops at a sign to noise ratio of two (SNR) and 11.8 stops at SNR = 1. Nonetheless, extra stops may be recognized inside the noise flooring (above the blue 11.8 line within the center diagram). Therefore, if you’re properly versed in postproduction, these further stops may be “excavated” from the noise flooring. IMATEST end result for exterior 8K ProRes RAW at ISO800 for the Canon EOS R5. Picture credit score: CineDJust to present you our present benchmark for dynamic vary, the ARRI Alexa Mini LF (full-frame) digicam reads 13.5 stops at SNR = 2 and 14.7 stops at SNR = 1 in ARRIRAW. That’s 3 stops extra, see our mini-lab check right here. Yet one more phrase on overheating: throughout exterior 8K ProRes RAW recording through HDMI, if “Standby: Low Res” is about to “On” within the digicam menu, no overheating happens anymore (whether it is set to “Off”, the well-known overheating limits apply). Sadly, exterior recording is triggered through the Atomos Ninja V+. On the digicam, the set off button is inactive.Dynamic vary of inside 8K H265 recording in Canon Log 3 at ISO800As talked about above, since firmware 1.3 the Canon EOS R5 permits additionally Canon Log 3 because the second LOG profile subsequent to the initially out there Canon Log. The preliminary C-Log profile confirmed an odd conduct of “reducing off” the noise flooring, therefore limiting the dynamic vary severely. Properly, C-Log 3 sadly is doing the identical.Right here is the waveform plot of 8K H265 Canon Log 3 at ISO800 – about 11 stops may be recognized, in addition to a weak twelfth cease.Waveform plot of the Xyla21 chart with inside 8K H265 C-Log 3 recording at ISO800. Picture credit score: CineDIMATEST confirms this, 10.1 stops are calculated for SNR = 2, and 11.4 stops for SNR = 1:IMATEST outcomes for inside 8K H265 C-Log3 recording at ISO800. Picture credit score: CineDCompared to the outcomes for inside C-Log (10.0 stops at SNR = 2 and 10.8 stops at SNR = 1) we do get higher readings, however not a lot. Sadly, these outcomes are on the low finish for a full-frame digicam. The Panasonic S5 for instance reads 12.1 stops at SNR = 2 (V-Log at ISO640 in UHD decision), the Sony A1 reveals 11.9 stops at SNR = 2 for inside 8K H265 recording (S-Log3).Switching the Canon R5 to 4k DCI full-frame recording improves the outcomes for Canon Log 3, on account of downsampling. 10.8 stops at SNR =2 and 11.8 stops at SNR = 1 are calculated by IMATEST. Nonetheless, the Canon R5 is greater than 1 cease behind its friends when it comes to dynamic vary within the mirrorless full-frame enviornment.Summary8K ProRes RAW exterior recording through the Atomos Ninja V+ opens up limitless RAW recording capabilities on the Canon EOS R5, with out overheating points. That may be a large enchancment.Nevertheless, exterior ProRes RAW recordsdata are very noisy, actually “RAW”. When it comes to dynamic vary (as anticipated), the identical outcomes as with inside Canon RAW recording are obtained – shadows are a bit much less noisy with inside RAW however very related values are obtained on the sign to noise thresholds of two and 1.The brand new Canon Log 3 inside Log gamma curve improves the dynamic vary with inside H265 recording a little bit bit however cuts off the noise flooring as properly. Nonetheless, I totally advocate utilizing Canon Log 3 should you want a extra storage-efficient inside recording answer. Therefore if you wish to totally exploit the capabilities of the Canon R5 when it comes to dynamic vary and limitless recording instances with out overheating, there isn’t a means round utilizing exterior ProRes RAW recording through HDMI on the Atomos Ninja V+.
