GH2 Seaquake + Slow Motion Burst Patch for 95MB/s SDXC

[Sage]

even with the sandisk extreme 30Mb/s it records 4-5 seconds

This is the correct time it is supposed to achieve with that card. The patch is meant for the 64gb sdxc - which gives a minimum of 7 seconds under max stress.

*Most purchase the sdxc 64 for spanning & *2x buffer write stability, that is worth the expense alone

 

[Park Edwards]

I dunno, man. Six to seven seconds of slow-mo is a long time. At max quality, it could be worth it for some.

Maybe more than 60 frames a second. Just don't think it warrants a $100 purchase for 7 sec clip. And still nobody has even put up a clip.

FOr serious, someone needs to put up some slow mo, though.

I think the Spanning, however, and the overall size of the car would warrant it. I can't get more than 12 minutes out of a 16gb card with the current patch and there's no spanning. I could see buying three 64gb Cards when a price drop happens and being able to rotate those on any shoot without fear.

Also, the cards will carry over to the next SDHC camera as well. I don't think Panasonic will abandon the format? And, it seems other manufacturers are adopting and pushing it forward.

They definitely will keep the format, but they'll be way cheaper in very little time. Seems silly to invest early when they're aren't very useful now. The current cards are very capable of writing very high speeds, so its not the card its the patches that arent written to work yet.

For spanning? I don't think the sub 95mb/s work with spanning at the highest data rate.

I guess it's a matter of what one sees as valuable, though.

 

[Park Edwards]

Do they span? Cause I'm reading mixed results. Sometimes it does, sometimes it doesn't. I also read somewhere it wasn't possible to span at all, and some have luck. I dunno, until it's certain it can span across all the kinds of cards, it just seems the patch is too fickle to have to spend an additional $100+ on something that's able to be fully utilized.

 

[Andor]

My questions on this hack (or any hack, I guess):

1. Is it ideal to log and transfer into FCP same as before? Or is there an extra step to secure the footage?
2. What is the max resolution video can be consistently recorded in? The IMAX mode is intriguing, but not as a 40 frame burst that dies after a second.

SAGE, can you please supply a video to demonstrate this patch?
We all appreciate the work by you and others, however we need something tangible for better understanding. It's been almost 3 weeks and 11 pages of discussion with no proof. I see a great possibility here, but would guess most are losing interest at this point...

Does anybody know how long the Extreme III 64gb 95mbps spans for with SeAQuake? It gives about 55 minutes, but will it continuously record for that entire length?

I'm transcoding some seaquake slo-mo footage right now. I shot 3 clips. One clip, was on a hanging wind chime that I was shaking around. Background was blurred. I was able to shoot for over a minute in 60p before I just cut the take. The next two clips were on a freeway in the distance with a lot of landscape, all in sharp focus. On both those clips, the card cut my take at 6 seconds. I'll upload when I'm done with the transcode.

*edit: just noticed Sage's note on the first post of the thread. The first clip probably went so long because I was at ISO 160. The next two clips were at ISO 250 - I had stopped my lens down to get a sharper picture because I wanted to see how it handled the detail. This is probably why two other clips stopped after 6 seconds.

The 95MB/s cards definitely do span with Seaquake, and will span for the duration of the card (about 50-55 minutes). However, one error I do get is that once I have a clip that has spanned, and I cut, if I try to continue shooting on that same card I get an error message that says I've exceeded the maximum allowed clips. Not sure about why I'm getting that, or if that happens every time. Have to do more testing.

I had the same issue last night. I also had approximately 20 shorter clips on there, so not sure if that affected the result. I'll be playing with that again tonight to see what happens.

Very interesting. Going beyond whatever the partition size is (more than once), I'm assuming it has to be bigger than 4gb on this card, it gives you errors. I'll have to check that myself. I guess a good test would be to try and record multiple clips 7min or longer.

Please, soon. I wasn't able to use the highest quality 60P patch with the cards I had, and would like to finally see what this looks like.

I need help...I'm a visual person and I am having a hard time figuring out how to get the setj to work with the firmware inside ptools3. I was able to upload the new firmware into the camera, but that was about it. I have the 64 95mb card....Help out a fellow dvxuser bro

Shot with Sage's GH2-X Patch (Driftwood's SeAQuake + AQ3 Vari Burst) on Sandisk 64GB 95MB/s SD Card.

1st clip rolled over a minute before I cut, ISO 160.

Next two clips cut due to write error after 6 seconds, ISO 200.

Lens: Canon FD 35-105mm f3.5
Aperture: f/3.5 and f/5.6 for final two clips
Shutter: 1/125
ND: 0.6

I've got another test coming up with a different custom setting from Sage. It will be shot at a detailed subject at ISO 12,800 with higher shutter speed - and I'll shake the camera. Stay tuned.

As a general note, any banding you see in the Vimeo file (particularly in the upper left corner of frame) is due to Vimeo's encoding and is not present in the source footage.

I'm really impressed with what has gone on here. I am a long time 5D guy with more than 35 lenses including 3 iscoramas and vintage Leica M, and really excited about using the the latter for the first time in years.

Just bought 2 GH2's yesterday.

From what I gather the go for Seaquake is Sandisk Extreme 32Gb 30Mb/s for 24p and something like Sandisk's 16GB 95Mb/s for 60p at 720 for GH-X?

Looking for decent cost effective solutions and because I prefer to rotate smaller cards with a data wrangler rather than put all my eggs in one basket.

Testing camera settings to see how long the bursts would last. I have no idea what I'm doing, so view image / comments through that prism.

All 3 shots exceeded the burst limit. There were several shots in between with the exact same settings that did not. Color always caused the shot to end at at 10s or so. The distance between the motion did not obviously affect the burst. There were several recording attempts from the same locations with similar motion that did not exceed.


Shot with Sage's GH2-X Patch (Driftwood's SeAQuake + AQ3 Vari Burst) on Sandisk 64GB 95MB/s SD Card

Lens: Canon FD 50mm f1.4
Shutter: 1/125
720p 60fps. Interpreted to 24fps in premiere
I believe ISO was at 1600 for all three in this clip.

Ok, question.

Will a 32 gb 95 mo work with the patch?! (Sandisk Extreme Pro) or do I have to get the 64 gb (I hope not, it's really expensive). I mean, it's just that it won't span as long, but I usually don't do takes that are longer than a minute.

hey man, can you post the file sizes of your .MTS vs the number of time length? I know it varies on subject matter but the ballpark info is useful too.
