Hello all,

I've got some issues with AN Cluster 7

I use CineMode 1080/24p - Smooth -2 -2 -2 -2 with SanDisk Ext Pro 32 GB class 10 95MB/s

But it always fails after 4 or 5 minutes. Do you know how to fix this issue ?

Regards, D.

I'm very happy with the GOP6 444Soft matrix, low light is sharper, better grain, and less macroblocking than I have seen on other settings. I'm going to edit up a few clips from this show after I get a friends wedding video done, just a raw preview:

@Splendidd, i dont know what chu talkin bout... that GTX vid is great.

The Garden one is better...

awesome.

maybe try out some intra patches on that crane?

@Splendiddd

First and foremost -- your work is better than 98% of beginners -- both in terms of composition and your technical implementations. The Cinema 4D and AE camera tracker work in that car video was outstanding and inspired me to mess around with the new camera tracker in AE CS6. So, you've got an outstanding eye, and you've got the brainpower to make stuff work. Stick with it and in a few days you'll blow away anything I've ever done.

Regarding your questions and my initial answers -- the two videos you posted are examples of everything I wrote. When you get that flicker/strobe -- it means the camera is moving too fast for the frame rate and focal length and distance to subject. That's it -- that's why it's happening -- you're moving the camera too fast. At 24p -- pans/moves need to be really, really, really slow. Look at the mom's garden video -- you'll see in some camera moves you don't have that flicker/strobe, yet in other shots you do. The difference is the camera is or is not moving too fast.

I assume you've got a slider (and if it's a manual slider it's tougher to learn) -- so run some tests. Keep your shutter speed at 1/50th, have your subject not too far away (three or so feet), use a wide angle (that Tokina is fine), and do a bunch of slide at different speeds -- way too fast through to way too (outrageously) slow. Then, examine the footage in post. You'll see the flicker disappear when you get down to some very, very slow speed -- and that's the rule at work -- that's the speed a pro cinematographer would know to use.

And, the higher the frame rate, the better motion will be handled.

As a long shot side note -- if you're using high bitrate patches for the GH2 and comparing it to the standard (from memory) 38 Mbps 7D footage -- your video card may be more challenged by the high bitrate stuff during playback -- especially if your video card isn't wonderful. But -- that's only a playback thought -- and has nothing to do with the rules I described and the issues in your sample videos.

So -- you're good -- and if you stick with it you'll be beyond great. You've got talent. The problems you describe aren't yours or the camera's -- they're the issues of the business. Stabilizer work should be done at 60p with the widest lens you can use. Slow that to 24p in post for the stuff that pleases normal audiences. Camera movements at 24p need to be slow, or you need to be focused far away and have the quick motion stuff be not in focus in the foreground.

I could go on -- but I've got to run. Filming stuff today. Good luck and enjoy the journey!

@onionbrain Thanks for your input Drew ;-) and YES i am a beginner and have to learn a lot, btw you are the one who made be buy the GH2, and i have no regret at all ! thanks for that, and i mean it...

@onionbrain quote:

"There are specific formulas for camera movement -- frame rate, focal length, distance to subject. If I'm doing a crane shot at 24p, then my lens is wide and I'm focused on something far away. If my subject is near, then my lens is as wide as possible and I'm moving slow, very slow. If I'm focused on something near and my lens isn't wide -- then I'm moving so slow it's beyond ridiculous. That's a translation of the formula. Google it -- it's all been discussed to death on every forum out there."

I am doing exactly that!

However, before i did a post here about the subject I tried to google it a lot and i did test a lot of options first, and if my final output would be 24p then its not a issue, but i am sorry but 30p and up looks so much better with crane shots...

Take a look at this vid, i did all the footage in 24p:

Lens on the crane shots was a Tokina 11-16mm @11mm and the aperture was around 8 orso

This video i did the crane shots @30p on the canon with the Tokina: Output video is 29.97

My opinion is that the footage @30p is much smoother and better to handle (as in the second video), i was just wondering if i could get the same results @24p... But as you said earlier in a private post in youtube, the GH2 720p mode is great, and MUCH better than the canon, and i can confirm that after testing. However i use a 30p sequence in PP just for the smoother motion.

So now i will try to use only the GH2 this weekend on sunday, i have a Mopar meeting to film (just for fun) and will use the 720p mode with the GH2 for the motion stuff, i will post the result later.

I think i will use the V7 nebula cluster for this...

Please don't blame me of not knowing my craft Drew, i am eager to learn and i alway take your advice in your vids :-)

Cheers

Rob

@Splendiddd Doesn't it look strange to blend 7D 30p with GH2 24p?

@SplendidddIn the movie camera has a shutter which is like a half drive. http://upload.wikimedia.org/wikipedia/commons/a/ad/Moviecam_schematic_animation.gif He makes good motion blur, but we do not have such a camera, we have electronic shutter. He will not give a smooth, but you can come close to this. At frame rates 24p should put 50 shutter speed, at a frequency of 60p - 125 (should be 120 but this is not present).

i had a v8 this morning :)

You could try to either record at 1/40 or even 1/30 shutter to get more motionblur in cam, or - what I prefer - record at shorter shutter times like 1/125-1/400 and apply reel smart motion blur @0.5 in post. Just note that the second method will get you into problems with translucent objects like filming trough as window. Lens flares will also confuse the plugin.

hook up your mac to a tv and try playback 24p footage at 24hz

@splendid....

MOTION JPeG has some very nice looking 30p hacks... 2k :) preloaded on cluster v7 i believe...

u say that 24p is choppy?? on my mediaplayer; 24p footage sometimes only plays back i frames with the different gop structure... making a choppy look, i normally use VLC Player to playback... it is freeware, maybe playback software is the prob...

however if u believe the footage looks choppy IN PP,, maybe 24p is just not the right choice for u...

24p exported as 29.97 is most DVDs... youtube and vimeo accept 24p files..

hope this helps

Ok maybe its not the right place to post this but there are so much pro's here so here goes:

I tested the cluster v7 with my camera crane and glide cam in HBR mode, because the 24p mode is just to jerkey... (Slider and tripod shots work fine though, panning with tripod already causes problems..) The thing i do not understand (and i've googled it a lot) is that 24p is shit for motion, i did test several cases with different sequence settings in premiere tested along a 24p sequence and a 29.97 visa versa, and the 29.97 is just so much better.

However, the thing that i do not get (and cannot find anywhere!) is how to set the GH2 to 30p... I thought i should bring it in HBR mode, So i recorded the footage in the HBR mode, and PP thinks its interlaced 29.97... however Streamparser on the pc says its 60i... so if i do a interperate footage in PP to progressive is that the right thing?, and IS it really 30p??? it looks better anyway (I read somewhere if its displayed as 60i but the footage IS 30p...)

Please help, 24p is great for detail, but for motion it sucks, someone mentioned changing the shutterspeed, but i tried everything, but it does not make a difference...(24p is still jerkey)

The strange thing though is that some " hollywood" films are 24p and there craneshots are just fine...(very smooth motion though the footage is 24p, how do they do that, or am i missing something?)

Some advice is much appreciated ! (And yeah i know that the 24p GH2 mode is the best, i am also worried about the conversion to 29.97, my output will be vimeo and youtube for now)

PS: the Tokina 11-16 (Canon Mount) works fine now, ive bought a KIPON adapter (with aperture control) Also the hack (Nebula V7) works great, however cameraplayback is not so good, but thats not a problem for me :-) Will add some footage soon.

Regards,

Rob
