Second camera to GH5 (for video)

Hello,

I have a dilemma. For over a year I have a Lumix GH5. Now I want to buy one more camera. Also mainly for video. Ideal would be GH5 or GH5s again. But I can only buy GH4 or G80 / G85.

I use this setting:
GH5 - 4K / 8bit / 150M / 50p V-log
GH5 - 4K / 10bit / 150M / 25p V-log

This is the maximum setting for GH4 and G80 / 85:
GH4 - 4K / 8bit / 100M / 25p V-log (8bit only)
G80 - 4K / 8bit / 100M / 25p Cinelike (no V-log)

I do not want 4K HDMI Recording Monitor (price $ 1000).

I have few questions:

1) Which camera is better suited for the GH5? GH4 or G80 / 85? I mean, mainly for video shooting.

2) An even more important question. Can I then link and combine GH5 (V-log) and G80 / 85 videos (for example, Cinelike) in editing software (I use Magix Vegas)? I need to get a video clip from both cameras. Will the difference be seen? For example, 20 seconds of GH5 video and 10 second video from the second camera, etc.

3) Is it possible to combine 8bit GH4 and 10bit GH5 (v-log)?

4) Any other ideas?

Thank you for your help and advice.

I use 2 G85 and a GH5 for video. With Cinelike-D they have very similar color. I can use 4K/25p on all three and I don't think 8-bit/10-bit has any difference (for light editing).

If I mix 4K/50p with 1080/50p the level of detail is perceivable. In practice, with 3 camera shooting in different angle and FL, no one can tell the difference.

If you mix Vlog with Cinelike I think the highlight would look very different. (Never use 2 GH so no experience).

You could use Leemig’s LUT to match G80 and GH5 footage.

The other main difference not pointed out is that the GH4 uses a 1.2x (horizontal) crop in UHD 4K and 1.125x in Cinema 4K, while the G85 uses 1.1x in UHD 4K and does not have a Cinema 4K mode. GH5 has no horizontal crop in 4K.

I agree with other comment that if the second camera is shooting a different angle and FOV people are unlikely to notice the difference if the colors/contrast are close enough.

However, given you have GH5 already, some ideas:

1) Try shooting some test footage in GH5 in all three modes (the 10bit v-log, GH4 equivalent 8bit v-og, and G85 equivalent 8bit Cinelike). Then try to match the footage. That will answer a lot of your questions directly without having to guess before buying a camera.

2) If it is critical that the footage much match in color, it is always an option to use the lowest common denominator (meaning shooting 8bit Vlog or 8bit Cinelike on your GH5).
