So I was shooting a live speaker event yesterday and wanted to try out FHD mode with a lower bitrate (20mbps) in MP4. I noticed it only gave me 27 min of record time and read the manual which it stated: "when the motion picture size is set to [FHD], [HD] or [VGA] in [MP4], you can continuously record a motion picture up to 29 minutes 59 seconds". I have an NTSC GH4, is there a reason for this? So basically if I want a lower bitrate, I'm stuck with AVCHD if I need the clips to span? This was the first time I've ever tried the lower bitrates. However, the manual states on page 60: "When the motion picture size is set to [FHD], [HD] or [VGA] in [MP4], you can continuously record a motion picture up to 29 minutes 59 seconds" or until the file size reaches 4gb. - Since the files size becomes larger with [FHD], recording with [FHD] will stop before 29 minutes 59 seconds."I tried a 32gb, 64gb, and 128gb card...same thing. It will span at 200mbps but not 20mbps? Weird
