    The slowmo 96fps looks better than 720p.

    Here's a gross hack for anyone wanting to batch-tweak their RAW stills so that Adobe products will read them. As @joesiv mentioned back on April 24th, doing this won't include any camera-specific optimizations Adobe may come up with when they start supporting the GH4. So it's best to hack a copy of your originals and re-import when the official stuff comes out.

    So here's the hack: in a *nix command line (Terminal.app on Mac):

    cd theFolderYourCopiedRW2sAreIn
    for x in * ;do echo -ne \x33 | dd conv=notrunc bs=1 count=1 oseek=890 of=$x; done

    Anyone want to suggest a more user-friendly way?

    @azza_act If the extra mbs makes a difference it's awfully subtle. All-I is definitely better with the GH4 but IMO it's still not as good as 100mbs IPB.

    Bottom line is that what DOES make a big difference is shooting 4K and downscaling it to 1080p.

    @AdamT does the extra mbps make a difference in 1080p MOV mode with the GH4 vs GH3?

  • AdamTAdamT

    @curtisMack in my opinion 1080p looks quite similar to GH3, except of course if you use the new profiles.

    Am I right in assuming that when I shoot longer videos the files will be saved in 4GB chunks on the memory card? Also I could not find any functions in the software that came with the camera to merge the 4GB files.

    I''ve seen a lot of 4K, and it looks great. How does 1080P look?

  • x_worpig_xx_worpig_x

    @T1000 Settings were: Shot with 20mm fd 2.8 at f4, 4k 24.00p, iso 640(i think), Cine D, -5 -3 -3 -5 0, shadow +2, highlights -2, 180* shutter angle. Graded in Premiere with Film convert + 3 way color.

    @x_worpig_x What are you settings on the video you posted at 11:50am?

  • ryancgloverryancglover

    First quick test with my Lomo anamorphic prime lenses. Cinelike D. 4k UHD down to 1080p.

    Flycam Nano + GH4. Coming from the GH2, I'm absolutely in LOVE with the GH4.

    Some thought from playing around a bit this week and last:

    • Focus peaking is very very good. I use manual lenses so it makes things easier. I prefer the low setting as it picks up more edges.
    • I'm still learning to get the hang of using zebras. I think I prefer keeping them at 100% and then adjust exposure as needed.
    • I really like the monochrome live view, it especially complements focus peaking very well.
    • I tried Mercalli v3 to stabilize 4k clips and am amazed at how well it works to get rid of microshakes and jitter. I was filming a concert using Voigtlander 42.5 handheld and after stabilization it looked rock steady. There is a bug in the software however... it compresses 0-255 mov into 16-235 colorspace.
    • very glad that shutter angle can be saved into a custom preset, no more frantic shutter changes when going from photo to video.
    • I'm not a fan of using a VF but GH4>>GH3. LCD is also clearly improved.
    • Sharpness when viewing 4k on a 1080 monitor is incredible.
    • No problems using Transcend 64gb UHS-1 class 3

    So.. who's making the report to Panasonic about the audio bug?

  • x_worpig_xx_worpig_x

    The compression is so bad. I'll try to upload a better version. All Available light. Cine D.

    @matthere thanks just did that and it worked :)

  • mattherematthere

    @jaycass you need to select 24Hz in the system frequency settings found on page 5/6 in the setup menu :)

  • jaycassjaycass

    got my gh4 but for some reason can not get it to film at c4k can any one tell me how to get it to shoot in that mode

  • silvesterdivassilvesterdivas

    Just did a quick test shot this evening with a Kit Lens from GX7, the Pany 14-42 and a 45-200. Not that expensive lenses, but the quality from this camera is outstanding even with Kit lenses outdoors. Love my GH4.

    @joe1946 That is amazing, my wife's gonna be pissed when I come home with a telescope tomorrow ;)

    Just a heads up on Monitoring:

    Most PC monitors and TVs will not be able to monitor from the HDMI in 24p modes. Even in non 24hz mode. It will say out of range or turn to 60hz.

    You can still monitor in 30p modes just fine. Seems the 24p modes are not displayed with a 60i wrapper and are true solid frames which only a good monitor and viewfinder can handle.

    Wish it was able to monitor in 24p on anything. Playback will work just fine. Wonder if thru the AV cable route it will display even in 24p rec modes.

    I am liking the noise on this camera, a big step from the GH2, very clean up to 1600 compared.
