Martin Wallgren (video on top): “Here’s an example of V-Log L when it’s done right, captured with the Atomos Shogun in 10-bit ProRes. There’s an original ProRes Proxy 4K file available for download from Vimeo. Check it out!”

Question from someone experienced with still images but not with video. Do I really need something like the Shogun? Aren’t SD cards fast enough to record 10bit ProRes?
The GH4 only records 8 bit internally. You have to use an external recorder via the hdmi socket to get the higher quality. I suppose it depends on what you’re filming but I think the internal recording is fine for me.
Ah! Thanks for clearing that up. As someone working in VFX, 10bit would be more or less mandatory if I go the 4K route…
And there’s certainly some tempting recording solutions coming out like the smaller atomos ninja assassin
No, it’s not the speed, the SD file structure is not capable of 10-bit.
The data starts as 10-bit but has to be dropped to 8-bit colour-space to record it on SD. The camera can handle 10-bit, the SD cannot.
It’s a bit odd but if the Shogon is given 8-bit, it converts it to 10-bit colour space and the Atomos CFast storage can record at 80Mb/s but an SD can run faster to 280Mb/s.
Cards doesn’t care what bitrates you use. Data is data and is stored accordingly like any data.
The camera can’t handle 10-bit on-camera.
I can even use 16-bit and save it to the card if wanted. It is only question of the camera!
Sorry, but that doesn’t make any sense at all.
First, SD cards do not care what you save to them. 8bit, 16bit, 32bit, doesn’t matter as long as it’s fast enough.
Second, if you record 8bit, and then convert it to 10bit, you gain NO ADDITIONAL information. It would be the same as just using 8bit.
My guess would be that the internal saving algorithms aren’t fast enough for 10bit, but can passthrough 10bit data through HDMI.
When @jefrs says “SD”, if you read “codec” instead, then the first half of post will make some sense.
I’ve seen tons of pixel peeping comparisons between internal 8-bit 420 and 10-bit 422 but that’s kind of missing the point. What I really think it would be useful would be pushing color grading in each file and then concluding how much better or not 10-bit 422 is for these more extreme situations.
Martin said in a presentation that without an external 10bit capable recorder, you have no real benefit of using the V-Log L format. You might as well use one of the two Cine-like formats, which will give you enough to work with in post processing.
