  • gh4 panasonic lanc zoom control

  • I Can confirm that the Manfrotto mvr901ecpl panasonic lanc zoom control does work with the GH4 and the 45-175 power zoom, also the start stop record button on it works as well. Tested on my GH3 and it does not work so a bit of additional functionality there that I hadn't seen documented, I wonder what else works. Going to try it out at the weekend at a couple of outdoor shows.

  • a dance trailer shot with GH4

  • A short nature/travel video I shot and edited. GH4, 1080p 60fps, standard, 200 Mbps.

  • As compared to the GH1 you also get much better dynamic range, detail, grading flexibility, and the ability to shoot high-quality 1080p 60 (or not so high 96fps). Zebras and peaking are also a huge plus if you're not using an external monitor. It's really not even close; the GH4 is a much better 1080 machine than any of its predecessors.

  • @waqarch "if u dont need 4k. just stick with GH1 not even gh2 or 3. thts my opinion."

    I don't agree with that whatsoever. I've been shooting with the 4k for about a month on multiple projects, all of which are shot in 4k but edited on a 1080p timeline. It gives you much needed space for re-framing or zooming on a particular shot that you wanted that extra little closeness. If anything, shooting 4k is the best solution for 1080p edits. My opinion.

  • @Vitaliy_Kiselev :) You're a wise man.

  • DE: GX7 has in-body image stabilization, but the GH4 does not have that. Is body-based image stabilization something that will only be in the GX series, or at least not in the GH? I suspect one reason why it may not be is because of noise, during video recording, is that the case?

    Inoue: The main reason the GX7 was made with in-body image stabilization, was so people could enjoy the other lenses.

    DE: Ah, so you were deliberately making that a platform that other companies' lenses could be used on?

    Inoue: Yes, yes, this is the main reason on the GX7. But on the GH4, there's an advantage to the heat sink for it to be stable. It's not impossible, but it's for a safety margin, to have a good heat sink. But many users have called for the GH series to have in-body stabilization, but for this one, we think it's better to not do that.

  • got it used it n did'nt like it. will explore more tomorrow & in coming days. but its jus like basic video. detail is nothing if its not cinematic. disappointed. even iso200 lowest 1. I can see noise in low light. i must say the screen is pretty good. but when u look on big screen then u admire vitaly work on GH1. to me GH1 got best cinematic colors.

  • if u dont need 4k. just stick with GH1 not even gh2 or 3. thts my opinion.

  • Quick camera test this lunchtime strolling around.

  • Interesting comparison..

  • @HHL - just shot four days of little training dramas for a blue chip client, and skin tones (ranging from Caucasian, thru Asian to Afro-Caribbean) have been great. Do you own a GH4, out of interest?

  • Can anyone verify that the GH4 works with the Manfrotto MVR901-ECPL or other lanc remote device for power zoom, I didn't think the GH3 did but this post here implies that it does with the 45 - 175 lens on which would be nice + I never realised but it looks like the 45 - 175 is parfocal or at least near enough for me the combination with a remote zoom for the horse competition bits I do would work nicely.

  • My first few shots with the GH4 - a cloudy day in Iao Valley, Maui. Except for opening shot, all were 60p to 40%. I shot some 96p but it looked so poor compared to the 60p that I did not include it - may be more useful for people shots but not nature where good detailed is needed.

  • GH4 skin tones: The opening few clips of this video are shot 4K with Cinelike V during late afternoon light with white balance on auto which resulted in very orangish skin. I should have done a custom white balance for better results but in post I did pull out quite a bit of orange yet still wanted to retain the mood and warmth of the golden hour light - open to comments about this grade... Also noticed that on Vimeo, the colors look more saturated and orangish than original. And Movist player results in a warmer, more saturated image than when played with QuickTime player. Another frustration is not having a professionally calibrated monitor.

    There are some Cinelike D clips later on in the video to which I ended up adding some warmth as they had much less of the already baked in warmth image of Cinelike V. Cinelike D profile is obviously the best when you have time to color grade in post but of course demands more skill which is an ongoing process for me. There are also several 96p clips included.

    I am impressed with how the busy patterned hat looks in the converted 4K footage with regards to moire and aliasing. The GH3 or hacked Gh2 would have surely not been able to compete in this matter.

    Since my old computer cannot handle 4K at all, until I am able to upgrade, all my 4K clips have to be converted by Firecoresoft to ProRes 422 (HQ) 1080p prior to NLE import onto a 1080p timeline - I would like to hear opinions on this approach as compared to dropping 4K onto a 1080p timeline - would there be a difference in final 1080p output quality between these two methods?

  • @Oedipax that was the first thing i noticed when dropping 4k down to a 1080 timeline. I then decided after that to only do 50% crop on 4k instead of full 100% crop. I hoped it was monitor resolution issues not showing proper 4k back but I'm no pro in that field to investigate.

  • @mo7ies, Will do so later - I'm working on another edit right now so it'll have to be in a few hours.

  • @ Oedipax Could you post some samples to illustrate the problem, please?
