I hope to start to work on hack soon.

I owned a GF2 since 2012 and bought a used GX1 recently for video shooting.

I hacked my GF2 with settings with over 100 Mbps in MP4 and the gear worked well with my Sandisk 45m/s card (U-1) Then I hacked the GX1 with the same setting (for example, driftwood's MOON T9) and used the same Sandisk 45 m/s card. Surprisingly GX1 always showed writing error due to card speed, which never happened with my GF2! I tried several lower mbps settings at around 60-70 mbps with my GX1, no writing error came up, but the video became very unsmooth when played in my computer. The unsmooth playback is obviously caused by the insufficient writing speed during recording.

Quite confused that GX1, a camera supporting SDXC U1 card, could have insufficient wrting speed problem which never happens with GF2, an older model without SDXC card support.

I know GX1 is not a gear metioned often here, but I still would like to know any GX1 owner or any expert ( like @Vitality_Kiselev or @Driftwood :)) could help with it.

BTW, this is my first post and I would like to take the chance to thank every setting provider like @Vitality_Kiselev , @Driftwood for bringing my GF2 to a new level of videography. I have so much fun with it!!!

Thank you!

The Sphinx moth is just beautiful. It's about as big as a hummingbird and just as fluttery. I got 3 or 4 pics out of about 50 that were in focus. Not very common in this region. They emigrate south every year. They have a super long proboscis for nectar. It was very interested in the petunias.

I do mostly stills, time-lapse, and occasionally some amateur videography at the moment. The second body should therefore be something good wrt stills (they probably all are), and something I could fool around with while the GH3 is primary on time-lapse-assignment, maybe even do a secondary time-lapse sequence (so internal intervalometer would be nice). Video quality should be ok but does not need to be on par with the GH3. The body should also be smaller (and a lot cheaper) than the GH3, since it will be a B-body I want to bring "just in case" in the bag when the GH3 returns, but which will probably often not be used at all. Compatibility with my Metz mecablitz 58 AF-2 for Olympus / Panasonic / Leica is also something I want.

Anyone in a similar situation? Or just with a good suggestion? I am currently leaning towards something Olympus just to get some experience with in-body image stabilisation compared to Panasonic OIS (and to get stabilisation with the manual / adaptor-mounted lenses).

So possibly the GF5 or GF3 or GX1.

I do not need the viewfinder or hotshoe... GF3 and GX1 are hacked...but GF5 not...

Any ideas when using them 50/50 for photo and video?

Any help welcome!

Is it a way to hack the GX1 firmware and able a function that would let make tethered shootings ? I know that a lot of people out there are waiting for that kind of stuff and Panasonic just doesn't care about its customers needs…

A hacked GX1 - which would enable stuff like high-ISO filming, manual video controls and higher bitrates - would make it the perfect travel camera. Small and light (with small lenses too, unlike the NEXes), yet great at video. Right now it's just "okay" at video, hacks would enable it to show its full potential. Since the GX1 allows direct recording to MP4 I guess that'll make it a little bit easier to hack than with the other models where you have to deal with the dreadful AVCHD format.

Since Vitaliy has said that G3 is next after the GF3 has been hacked, I think it would be fitting to work on the GX1 right after that. I've read several places that the GX1 and the G3 is quite similar. They both have the same sensor apparently. Vitaliy have self said that "It is G3 in other body, without EVF and all else is almost the same." That'll hopefully make it easy to hack right after the G3 has been hacked..

A firmware update was released a couple of days ago, which I guess will make the process a little bit easier too.

What do you guys, and especially Vitaliy, think?

[More to come...]

The DMC-GX1 employs full HD 1,920 x 1,080 videos in AVCHD (MPEG-4 / H.264) format. The AVCHD format features almost twice the recording time in HD quality than the conventional Motion JPEG. The AVCDH matrix for i and p frames in 1080i is the same as each other (as seen in the attached file GX1 picture parameter set). Notably, the 720p matrices differ from each other from i frames to p frames (notice both pps matrices attached below)

Video AVCHD:

NTSC [Full HD] 1,920 x 1,080, 60i (sensor output is 30p) (FSH: 17 Mbps) [HD] 1,280 x 720, 60p (sensor output is 30p) (SH: 17 Mbps)

PAL [Full HD] 1,920 x 1,080, 50i (sensor output is 25p) (FSH: 17 Mbps) [HD] 1,280 x 720, 50p (sensor output is 25p) (SH: 17 Mbps)

Video MP4:

The DMC-GX1 can record videos in MP4 format. This format is suitable for editing videos on a computer or uploading those to websites. Resolution can be selected among 1,920 x 1,080 (20Mbps), 1,280 x 720 (10Mbps), and 640 x 480 (4Mbps), all at 30p (NTSC) / 25p (PAL). The mp4 mode records files to the DCIM folder. See attached 1080 p25 mp4 header info and streameye graphic for GOP and progressive confirmation.

The usual mini HDMI Type C. Video: Auto / 1080i / 720p / 480p (576p in PAL system)

Optional accessory (essential): Live View Finder (field sequential color, 1,440,000-dot equivalent).
