Card Write Speed Error with GH13
This has happened to me twice, and it's concerning me. I'm shooting on a hacked GH1, 720/60p. Tonight I was at a rehearsal, shooting some random shots to get a good feel for how it handles in the church. I panned around while recording, and suddenly got a message saying something similar to this: "motion recording stopped because of card write speed."
I'm using class 10 Panny SDHC cards, and this shouldn't be an issue -- especially when only shooting 720p. Both times this has happened, I've been panning. Of course, I'm concerned that this will happen in the middle of the wedding tomorrow, and I won't necessary know it because it's going to be an unmanned back-of-the-church camera. Any thoughts? Thanks! |

Re: Card Write Speed Error with GH13
I just viewed the clips, and for the most part, the GH1 is beautiful.
But . . . moire! The gigantic wall behind the altar is brick, and the dreaded dancing rainbow reared its ugly head. What a disappointment. |

Re: Card Write Speed Error with GH13
Corey, you might consider uninstalling the hack. The one wedding's worth of hacked GH1 footage I'm currently editing was not kosher, shot on a hacked GH1.
The moire,? Bummer for sure. I've had absolutely NO issues with moire with the camera, it is rock sold for, me, albeit tricky to use.

Re: Card Write Speed Error with GH13
Well, for today's wedding, I'm going to use the other GH1 -- the newer, unhackable one -- just to play it safe.
Jeff: I was suspecting it had something to do with the hack, as I wasn't able to find many people who had this same problem. And if you think about it, those who use hacked GH1's are likely not shooting 720p. I loaded up Ptool this morning and started rooting through it again. Something I hadn't noticed before is that when you increase the bitrate, it affects both 1080 and 720 (FHD and SH modes). For some reason, I thought the bitrate hack only affected 1080. When I hacked this months ago, I put the bitrate at something ridiculous . . . 42Mbps or maybe even higher. It makes sense to me now that when the camera is shooting 60fps, the card may have a hard time keeping up with the data flow, even though it's only 720p. And this could possibly explain the moire? High bitrate, high fps, lots of tiny parallel/perpendicular lines in the frame . . . |

Re: Card Write Speed Error with GH13
Update . . .
I shot the wedding on Saturday using the unhacked GH1 as my stationary back camera. No moire this time. Also, no card write errors. I also used the camera for pre-wedding shots and most of the reception, and it performed flawlessly. The only difficulties I had with it were due to my limited experience with it -- things like focus and exposure. But those issues will get ironed out as I keep shooting. I updated the hack for my other GH1. I don't want go without the hack all together, because I like having that native 1080/24p option at my disposal. But I set the bitrate down to something more conservative -- 24Mbps. I haven't tested it out yet, but plan on doing so soon. |
