I have not measured the bitrate before/after the firmware upgrade, but it is interesting to see that the difference is so big.Fredrik Gløcknerhttps://www.blogger.com/profile/07523430148487818493noreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-43579072818412944232015-03-23T19:57:56.264+00:002015-03-23T19:57:56.264+00:00Hej Frederik, first of all thank you very much for...Hej Frederik, first of all thank you very much for this very valuable blog!<br /><br />I've noticed the same thing: while GH4 firmware V1.1 gives me roughly 80 Mbps in the video stream of the 4K 100 Mbps format, V2.x have increased to around 100 Mbps. A similar thing goes for the FHD 200 Mbps setting, where firmware V1.1 gives me around 150 Mbps bitrate in the video stream vs 200 Mbps in the Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-82173289597751578662015-02-17T09:20:38.304+00:002015-02-17T09:20:38.304+00:00It sounds like the problem is your computer.

As you are able to use the files for video editing, this doesn't sound like a big problem. <br /><br />Just don't playback the original files, but use them when editing videos and encode the outcome in a format that your computer can handle.Fredrik Gløcknerhttps://www.blogger.com/profile/07523430148487818493noreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-84569650007290078152015-02-17T05:23:07.569+00:002015-02-17T05:23:07.569+00:00Hello everyone,

I shoot .mov and when I shoot on all different modes (1080 / 1080 96fps / 4K ) it shoots no problem.<br /><br />But when I copy the video to my Mac and I play the original (H 264 mov) files from the camera, the video is lagging very very much.
