The Panasonic G1HD | GH-1 Video Mode : A Real Video Mode

mine is on charge now...be shooting with it later...

LOVE the red colour. I asked if I could get red..little mic is cool too...
 
RECORDING TIME -- Sandisk 4gb Extreme III 30mb/s SDHC Card records 62 Minutes of Full 1080/24P 17mbps Video and Audio ... non stop. Camera's just BARELY lukewarm to the touch. Fully Operational. Started this test on two battery bars left and still have one left over.

How is this possible?Anyone know what's going on? Theories?

Image Degradation will be tested by others I'm sure. I personally dont have the time right now but can't wait to see what others find out.

Theorotically its correct....
Generally 25Mbps makes nearly 13GB/Hr File.
19Mbps (which is 720p HDV) makes nearly 7-8GB/Hr File.

Now it is 17Mbps, little less than Hour in 4GB is very close to make sense.

Anyways that could not go more then that in 8GB (or more) card.
Because FAT limitation is there. This doesn't mean its a limitation of camera.
Its just a FAT File system limitation of 4GB per File.

And as per as I know there is no card in development in NTSC file system.
 
sooooo.... which is it, FHD or SH? I mean it makes sense that FHD would be the highest but... who knows.

The red one looks pretty cool. Though, I'd probably be tired of it in a week and regret not getting black later.
 
According to the tech specs, there's SH mode (17mbps), H mode (13mbps) and L mode (9mbps). Make sure you're in SH mode. If you've been testing everything (and been happy) with L mode, then you'll probably be squealing in delight with SH mode!

Interesting. Panasonic's docs agree/disagree?

According to those links, the GH1's "FHD" recording mode should be "1080p24 AVCHD @ 17 megabits/sec VBR". I think ...
 
It does. But I seriously MUST have something set wrong if the Clips only reading 9mbps and not the 17. that's nearly half.
 
Is it somehow dependent on motion? Meaning do you think if there were motion in the video it would compress it more maybe? Just a stupid thought.

If you can stand it, do another "FHD" test, but this time with the GH1 aimed at a scene with continuous movement. A torture test might be aiming it at a TV that's displaying something, anything moving. Or a scene with grass/trees/surf blowing in a breeze, etc.

Does recording constant motion hugely affect the GH1's maximum continuous record times?
 
Just got mine! I tried the live composite out put and it does spit out a live image through the a/v cable.

The only issue is 1. You have to have the LCD flipped on, 2. It stops spiiting out a live image once you press record. So its a no go for having a directors monitor.

Maybe kholi can try the test with the hdmi again? You open the LCD, press display, and then hold down the Trash button for 10 seconds about- the screen flashes for a second and then you get a live image. *** note -- this only works if you have a memory card installed in the camera ***

Save Yourself some time....

"The camera can record AVCHD movie in SD memory cards up to their full capacities.
However, the camera can record Motion JPEG movie up to 2 GB in SD memory cards. The camera shows the time
it can save (remaining time to record) computed from 2GB space in recording Motion JPEG movie even though
your memory card capacity exceeds 2 GB."

What Class is your SD card?

...because it "is strongly recommended to use SD memory cards whose card classes are larger than Class 6 for movie recording. For
Motion JPEG movie recording with the quality HD, WVGA or VGA fast type SD memory cards labeled as at least 10 MB/S
is recommended."

Just tried that Composite thing as well. Does work But cuts out afterward like Hunter said.

Will try the HDMI in one second.
 
Kholi, I'm using Nero to play the files back; you can tell it to display additional data such as bitrate and frame rate. On the 0040.mts file, it drops as low as 6 megabits in places.

Try some full motion shots in FHD and SH mode (shoot basically the same thing) and try playing them back in Nero, or, if you don't have nero, shoot 'em on over and I'll try 'em.
