As a part of our ongoing testing of Canon’s EOS R5 II, we have been getting a way of what its video seems to be like and the way it’s sampled from the digital camera’s sensor.
As you would possibly count on, the 8K video is extraordinarily detailed as is the 4K/30p ‘HQ’ footage derived from it. The road-skipped 4K video in normal mode is far much less detailed, although it is price taking into consideration that the take a look at targets on a technical chart will present these variations way more prominently than they’d seem in transferring footage.
We additionally shot among the digital camera’s 8K Uncooked footage in each 30p Uncooked and 60p Uncooked Lite kinds. These additionally seem very detailed although would wish extra sharpening and distinction to be utilized for them to match the out-of-camera, gamma-encoded H.265 output. Right here we have simply used Remaining Lower Professional’s built-in Canon Log 2 LUT to carry them to a workable Rec.709 state, with out making use of any additional processing.
Sadly, for those who have been hoping for 4K derived from this 8K/60 seize, the digital camera’s 4K SRaw possibility seems to be line-skipped. Its readout fee is identical as for 8K/60, so there is no rolling shutter discount available for that line-skipping, only a discount intimately (and file dimension).
Rolling shutter charges
| Decision | Body Price | Mode | Rolling shutter fee (ms) |
|---|---|---|---|
| 8K (1.89:1) | 59.94 | Uncooked Lite |
12.8 |
| 29.97 | Uncooked | 17.3 | |
| 29.97 | H.265 | 12.8 | |
| 8K 16:9) | 29.97 | H.265 | 12.8 |
| 4K (1.89:1) | 59.94 | Uncooked | 12.8 |
| 29.97 | Uncooked | 17.3 | |
|
119.9 59.94 29.97 |
H.265 | 7.2 | |
| 29.97 | H.265 HQ | 12.8 | |
| 4K (16:9) | 29.97 | H.265 | 7.2 |
| 29.97 | H.265 HQ | 12.8 |
Our assessments recommend the EOS R5 II creates its video from three totally different readout modes: none of them almost as quick because the digital camera’s e-shutter mode in stills, however all fast sufficient that rolling shutter isn’t going to be one thing it’s important to fear about. Curiously the 30p Uncooked and SRaw modes seem like learn out extra slowly than the 60p modes, which we would guess is a solution to scale back temperature build-up, however a lot of the digital camera’s 10-bit gamma encoded modes are shot on the larger pace.
We are going to regulate temperature efficiency as we use the digital camera extra.
