Lossless rencoding Cannon 4k MJPEG

You can save a tone of space with the C200 by shooting XF-AVC 4:2:0 8-Bit.

I see, I gotta say though, 12 bit and even 10bit Raw on C200 looked drop dead gorgeous. There is actually no end I realize now.

Ignorance is bliss

4k is 4x larger than HD, thus takes 4x the data of HD ..even then not sure how you could end up with 40tb (or even 10tb for standard HD)

Maybe you're thinking of somehow recording uncompressed RAW footage to disk or something? that's really meant for super high-end production, not wedding videography, where compressed video is perfectly acceptable.

as for the slow motion, it's possible to slow down footage in post. (technology can fill-in frames), but most videographers merely drop down to 1080 to shoot at higher frame rates. - and slow motion wedding video is ok to be slightly soft and dreamy.

Canon D4 doesnt have any codecs on board the camera that do this

Neithed does C200.

I am comparing these with a panasonic GH5 that can do 4k 10bit encoding output.

So this means, at least for some amount of time, that footage will have to be encoded

Love the 4k 10-bit 422 on my GH5 and also V-Log L is very useful, especially in low light where it lets you get away with more (although it's a paid upgrade). Dual-IS2 is great too. Video-AF some way behind the Canon's with DPAF tho...

Not just focus, I fear even lenses. But 10bit is the way forward really and Canon cannot do it in an efficient format

Actually can I confirm that the Panasonic GH5 can shoot 4k 60p 10 bit 4:2:2 Internally. Thanks

No, it cannot. What is your source? 4K60p 8bit 420 internally. 4K30p 10bit 422 internally. The GH5 can output via HDMI 4K60p 10bit 422.

I may repeat something already said, but no time to read the full thread.

Last year I did the same (my daughter wedding), one shot of non-stop 47minutes 4K24p 8bit 4-2-2 ProRes 240MB/s gave 230GB. And easy encoded, more static subjects.
ProRes is a loss codec, also professional level (broadcasting).
Use of an SSD was in the process, clear HDMI out to an Atomos external recorder with a 2TB Samsung SSD Evo 850.

Lossless, as "RAW", I do not think available in a more or less comercial camera body, and also there are some codecs with the name RAW (!?), they do not record video RAW. But I hope without reading the specs, these RAW should give a very good quality anyway.

Check here: https://en.wikipedia.org/wiki/Comparison_of_video_codecs

Just think, 4K is about 8Mpix and at 24fps and 8bit it means about 600MB/s (aka 4800Mbps). Want 30fps is about 720MB/s, double as 60fps is about 1.5GB/s = 12Gbps, somewhere more than the best performance of an commercial SSD drive (around 5-8 Gbps).

Just some professional equipment can do a 4K RAW, 24 fps or more.

If recorded on a "media card", SD or any else, this is not posible.

I would advise for a ProRes codec, similar ones (DNxHD or some RAW codecs do a similar job), high bitrate around 240MBps or more, best would be a 10+bit 4-4-4 (well, 4-2-2 will do it).

This is really high quality, as I said for TV broadcast (professional level).

You should manage something equal or a bit less, should be very good.
