This short should be re-edited for web shortly. Shot on Boom! v1. Got us first at our Uni film fest! Thanks @driftwood @Vitaliy_Kiselev and @shian for all of the tools you've made available. Here's a screen grab in the mean time.

Looks very good. What was your workflow? Lens? Hack settings? You should turn this into a film

@nameless It kinda has the vibe of a modern day "A Clockwork Orange" I like it. Where did you find your actors because it seems like it isn't their first time in front of a camera.

Great Job. Im waiting for more.

@rsquires Thank you for taking time out to view and comment it is appreciated. Its actually a theatre play that they are now seriously considering creating into a film due to this trailer.

Apologies in advance for posting it up again but i really need to get as much constructive criticism as possible to take on board going forward.

I've also included a different 30 second teaser trailer this time.

@GravitateMediaGroup Same but tuned more. Also it contains the deblocking settings from the GH3. You must remember however that the GH3 enjoys the economy of 8x8 Transform with most of the picture whilst the GH2 does not - hence why 4x4 is seen throughout using this setting on the GH2.

On the GH3 image areas with high detail are compressed using 4 × 4 pixel blocks, while areas with low detail are compressed using 8 × 8 pixel blocks. The latter generates less data; therefore, more bandwidth is available for data from areas with fine detail.

sorry if this has been asked, but is the GH3 matrix patch in this topic the same exact patch as the first one from a while back or does it have some modifications?

@Nameless That looks amazing. Great to see actual content here that looks good and isn't just 10 minute takes of water and trees! Is it a play or a series. Really great work

Nameless

@Shaveblog Wow....That comment really means a lot to me as i consider myself to be still learning. Thank you very much for your kind words.

Shaveblog

@Nameless Thank Christ these ultra film-like patches are now freely available to artists such as yourself, so that your work can be presented and preserved in the highest possible quality.

Please, never stop gifting us your magnificence.

This was shot using Cluster v7 Drewnet and Boom settings... Thanks again @driftwood and all contributors for making this all possible.

@mlysbakken Interesting images. Kinda looks like a more intimate/indie version/variation of Hangover. Thanks for posting. Keep rockin!

Here are a couple of ungraded stills from my newest short, shot with AN Drewnet Sharp2

@Onion. Looks great. I wonder how much the youtube compression had to do with the water.

Filmed with the Apocolypse Now Intravenus settings. My first time to use this hack. Works quite well but boy does it take up a lot of space. I think I got around 20minutes on a 32GB card. The detail this thing captures is amazing. I used the 7-14mm and 12-35mm lenses by Panasonic. Enjoy!

@driftwood

My thanks for the explanation and link.

I blindly screwed with stuff and came up with a long-gop version that indeed gives about 85 Mbps at 24h. I haven't had time to play with it because I'm in the midst of a mini financial crisis while researching and script writing for a film that was supposed to be aired on regional public television yesterday. The issue is that I truly "blindly screwed" with settings. So, if you as our "Guru" are able to effortlessly render a high bitrate long gop version that capitalizes on the strengths of this new setting -- I'm very, very grateful.

As always -- thank you!

The GH3 Setting is purely experimental to see what people think about the matrix that is running on the new GH3 and patched into a GH2. Its not brilliant but its okay as it isnt really designed for the GH2. For me I would have to agree with onionbrain in that works better in the GH3's Long GOP settings and I wouldve recommended a different matrix set for the All-Intra modes of the GH3. Pany have this matrix flatly across all the mov modes in the current GH3 firmware I tested.

Correction: @onionbrain In simple terms the GH3 codec's use of 8x8 Luma Transform and motion compensation using 8x8 blocks offers economical processing of the block size (4x4 blocks offer the smallest residual energy and more accuracy but can involve complex calculations).

Looking through the GH3 footage Ive seen so far most of the picture is predicted using 8x8 Transform along with 4x4 on stark 'highlight' frequencies changes - typically around edges where luma change is predominant.

There's loads of links regarding motion estimation, motion compensation prediction, DCT transform and quantization around here and the net.

A nice understanding of the High Profile and the 8x8 additional transform found in the GH3 is here: http://www.w6rz.net/H264HighProfile.pdf

Below are two pictures detailing the GH3's employment of 8x8 Intra Prediction for most of the picture and 4x4 Intra prediction is used for edges/ high contrasting luma frequency variations. This is from a 24p All-I GH3 recording. Notice that the i frames in the GH3's encoder are around half that of the GH2. This is the same for a whole range of detailed recordings - the bitrate, cpb coded pic buffer, and frame size in bits are substantially reduced in this rate control. IQ/QP is 20 like the GH2 but I believe somewhere in the Panasonic interpretation of the encoder is a cbrandin style 'Auto Quantiser' running off the base QP/scaling matrices - just like the GH2 after a few seconds the average QP improves tremendously.

The GH3 is producing mean QP of around 14 in a large amount of my GH3 tests. Significantly, the Intra Predicted 8x8 mblock transform is providing less complicated calculations with almost no loss in residual power yet in terms of HVS is still very pleasing to the eye. The use of High Profile means at least 12% increase in memory requirements satisfied by the new and improved processing power of the GH3. H264 bitrate ceiling limits for High Profile means in theory we should be able to push the GH3 hacked to over double its current bitrate without problems at decode level/memory bandwidth. This will go to improving any artefacts that we see in the stock implementation.

@willianaleman:"The fullscreen for this video is locked"

This is bollocks! Fullscreen of this video is definitely playable and available for all modes (240p - 1080p) in Youtube !! By the way this is off topic and has nothing to do with this thread.

willianaleman

I'm using a 32 inches 1080 monitor. The fullscreen for this video is locked. I can see other videos in fullscreen without problem, so it seems to be that this issue is not at my end.

Thanks for your reply.

matt_gh2

@willianaleman To get full screen of YouTube videos, you can click on lower right part of video frame where it says "YouTube". That takes you right to the same video, but now you're on YouTube.com and you can enlarge it to full screen. (don't forget to then bump settings to 1080 for best image).

Also similar thing happens with Vimeo videos that people post/embed. Some Vimeo videos won't play HD, unless you click on "Vimeo" to get sent over to that video on Vimeo.com.

Hope this is helpful.

willianaleman

Thanks for the test. Fullscreen of this video is not available in Youtube.

Below are clips from the earlier evaluation of "Quantum GH3 Matrix Setting Test 2.” The water motion looks better on the small screen -- but my initial reaction was honest after viewing it on a larger screen. Other than the water motion issues -- it really is great looking.

@fomalhaut3

Great job on that. Outstanding production value.

How does the new gh3 matrix 2patch compares withh Cluster v7 'Apocalypse Now - Nebula' 6 GOP???

Howdy, Stranger!
