Vesku Posted November 14, 2017 Share Posted November 14, 2017 The new IS-lock is great. Surprisingly it improves gimbal-like walking videos. Combined with E-stabilator it makes walking with camera quite smooth. Quote Link to comment Share on other sites More sharing options...
matthere Posted November 14, 2017 Share Posted November 14, 2017 I'd like to see the 80mb mode (from the G9) for stills on the GH5 please Panasonic! brentil 1 Quote Link to comment Share on other sites More sharing options...
jonpais Posted November 15, 2017 Share Posted November 15, 2017 Is it true, as Serge Broslavsky writes in his petition to Panasonic (written prior to firmware update v2), that ALL-I 400Mbps only delivers around 85% or so of the bits-per-pixel quality of IPB 150Mbps, and that IPB 400Mbps would have higher image quality, making grading V-Log Lite easier to grade? I'm asking because I haven't seen any samples in which ALL-I 400Mbps has convinced me that it is any better for still subjects. Quote Link to comment Share on other sites More sharing options...
Vesku Posted November 15, 2017 Share Posted November 15, 2017 I have shooted tests using 30P 150Mbs ipb vs 400Mbs all-i. In quite static videos the ipb has little less compression faults than all-i. When watching enlargements of backgrounds the ipb vs all-i is like comparing high quality JPG vs medium quality JPG. In Adobe Photoshop JPG quality scale it is about quality 5 vs quality 7 (scale is 1-12) for stopped frame. IPB may cause some little odd things but it is very rare. In motion the quality difference is backwards. All-i has less macro blocking but ipb is still very good. When making the final delivery version (ipb) the motion macro blocking is always worse than original. In static scene we may see the little compression difference in final rendering if using high enough bitrate. Quote Link to comment Share on other sites More sharing options...
wildrym Posted November 21, 2017 Share Posted November 21, 2017 I've got some questions regarding GH5: - Is the 1080p vfr (120 p etc...) , 10 bit or 8bit? Is it 200 mbps since v 2.0? - does 4k 60p also benefit from 400 mbps? ( if not, i dont get it, since it would have improved compression issues using vlog) Thanks!

GH5 1080P VFR has only 100Mbs 8bit 420 ipb codec 4k 60P has only 8bit 150Mbs 420 codec. Dont worry, the 4k60P in GH5 is very good. It is very hard to see macro blocking. 4k60P all-i would need about 800Mbs to be good. Quote Link to comment Share on other sites More sharing options...
