Panasonic GF1 ‘400 24’ settings – 720/30 100mbit 422 from huw jenkins on Vimeo.
Emmy Award winner Huw Jenkins just sent us the link to his video shoot with the patched Panasonic GF1
Panasonic GF1
with 100Mbit/s!
“Shot with my new ‘400 24’ settings.
these settings allow you to record clips of up to 2 minutes 27 seconds on the GF1 at 100mbits, 422 color space, 720/30fps
more stable than ‘410 24’, you can now delete from the class 10 SD card and re-record without needing to format (at a push, see below).
single error trip:
‘motion recording was cancelled due to the limitation of the writing speed of the card’
each time you turn on the camera, a single error trip will occur. as with all GF1 100mbit settings so far, the first high bitrate clip recorded will trip this error message, ignore it and continue shooting. the gf1 will record perfectly till you switch off the camera.
card formating:
use a freshly formated class 10 card. if the card already had data on it, files might be fragmented which is more than likely to cause multiple recording errors. this also occurs when deleting files and re-recording. Sometimes my sd (sandisk) can handle this, other times it fails.
when the card is full, the last 10-30 seconds on a 8gb SD fails to write.
file size / clip length:
the maximum size file i can record at any bitrate is 1.85gb. when using ‘400 24’, the bitrate is variable, depending on the complexity of the image being recorded. here is a clip length guide
4 minutes 42 seconds at 56.29 Mbits/second
2 minutes 27 seconds at 100.09 Mbits/second
the settings, for ptool 3.36 or higher:
change only the following
version change: 1 higher than your current version
all Q settings: set to 400
all T settings: set to 24
240->244: selected
leave everything else unselected”

Can someone explain to me what the use is for 100 Mbit??
@ Chow
hmm.. better video quality?!
Doesn’t look at all different from most HD videos Ive seen on-line in terms of quality… Maybe its the playback on my screen…
Chow > 100 Mbit/s is probably overkill for most applications, but given a choice, I’d rather have too much than too little. Right now Panasonic factory firmware gives me way too little. I’d rather drive a Ferrari at 65MPH on the freeway, even though it is capable of 200MPH, rather than a Yugo with a misfiring cylinder that barely makes 45.
Bu > You simply can’t critically evaluate these clips from a technical perspective unless you download the original file, not compressed additionally by YouTube, Vimeo, etc… unless you only deliver to YouTube and could care less about quality above beyond the web as a target.
Hmmm … 221.184.000 bits/sec is the amount of data contained in RAW per second on a 1280×720@30fps with 4-2-2 color space (8 bits) … 100Mbps is a little less than half the RAW rate… so… i would say it’s pretty insane … (specially considering the compression abilities/features of algorithms)
True to be said, 25Mbps are usually enough…. but some video folks the more the better…
and yes…. a Yugo with a misfiring cylinder is quite epic to drive (or watch)… specially the 0.9l version … but a Citroen 2CV 375 cc would make even more epic … xD
You’re right Tom, web is my only target 🙂 Though I don’t mean to come across as too flippant, for those who present/display on a giant screen I’m sure the 100mbits come in handy…
More than about 30Mbps setting, GF1 in camera playback is not possible. I tested a lot, and I concluded 30Mbps is more than good enough.
I’m just jealous at all the work being done on the Panasonics. Makes sense with the focus on the GH1 first, and no real counterpart from Olympus.
Still would love to see the Olympus m43s getting a similar buffing. Perhaps there will be an inspired splinter movement. Of course can just pick up a GF1 pretty cheaply these days, both new and used.
Nice, but what would be far more useful would be a 720p 60fps hack. I think the 30fps limitation is what stops these cameras from entering the world of serious videography.
