flash melting codec?

I've noticed this a couple of times, I can live with the rolling shutter / flash but this is a killer:




doesn't happen all the time - I'm wondering if it's a certain type/brand of flash?

Was this with the Firmware hack? Or was it with the default settings?
 
The "rolling" is related to the shutter speed and the flash going off. You can run some tests to see what shutter speeds will work well when someone is shooting stills while you're filming.

The melting is possibly the camera trying to quickly readjust from the sudden over-exposure.

It's just something you have to live with, if you're going to try and use it for professional wedding video...which it isn't intended for...being a consumer grade camera.

I've had photog's gear completely shut down the recording on the GH1 and corrupt (lose) the files a few times!

That being said, the GH1 is CHEAP, and the low light capabilities with the 20mm f1.7 is pretty cool to shoot with at the reception...so I've been shooting weddings with the GH1 FULL TIME for about a year. And it's absolutely horrible as a ceremony camera (kit lens can't compete with the zoom range+low light capability of a regular video camera...not to mention the lens mount loses it's connection with the camera when zooming quite often).

I'm sure the "hacked" firmware would help the flash-induced "mud", but I wouldn't dare start screwing around with the firmware of a camera you are using for professional event work!! Hopefully Panasonic will remedy the codec somewhat in the GH2.

Good luck!
 
i think the flash is surprising the codec just like high detail and movement. would like to know if you are running the higher bitrate firmware or original firmware. i would like to think the higher bitrate would possibly reduce or eliminate this oddity.
 
Couldn't replicate this just now on the new firmware (using "D" settings on AVCHD 1080 24pN). I think like Mr Fanny said it's a symptom of the lower bitrate codec not being able to handle sudden shifts in detail plus movement. I'll upload a couple clips so you can check it out.
 
If the higher Bitrate in AVCHD provided by the hack is not enough to eliminate your problem, you may record your shots in high bitrate MJPEG mode. Because MJPEG is an intraframe codec, it won't give you any mood.
