  • after a long holiday today Flowmotion discovered - heute V 2:02 going to tested here on the coast of the Baltic Sea - thank you for this patch @LPowell and curious how Flowmotion against Nebula 444

  • @valpopando:nice footage and such an exceptional place....

  • @Mirrorkisser Thank mate ! I should plan to comeback there at night time !!!!! Creepy Horror movie ; ))))

  • @valpopando - MeShUgGhAvertigo, wow, that is one hell of a flow motion test!

  • @valpopando three beautiful pearls :)

    Apice Vecchia is a perfect set for a ghost movie

  • Hello is there a tutorial to install the firmware please ?,

    i dl the ini file, i dl the 3.66 ptool, i had the v1.1 bin crack, i put it in the folder, then it doesnt works, i had to load the v1.0 bin file, it works....weird

    thx for support

  • @butt can you tell us which settings did you use for your crazy edit ? thats dope ! thanks

  • @vgtah I think you mean the video of @valpopando - He will have accelerated the clips in the post for this effect

  • test with Flowmotion v2.02 patch of LPowell - I think the patch is very good - nice soft Graduation - good sharpness - awesome colors - illustration of water is great - a great allrounder - thank LPowell

    natural -1, -1, 0, -2 Lens: Pana 14-42mm, Pancake, Nikon Nikkor AI-S 24mm f2.8

  • @butt i saw the acceleration, im speaking of the video mode that gives that animation effect, i knew it but i would like to know the set up precisely. I can t install the new firmware, im damned.

  • @vgtah I think you should take the PTool version 3.65D for Flow Motion - not the 3.66D also applies to the patch from Nick (!?) I think - or?

  • thx for the tips butt, im on it

  • @butt Really nice video butt. FM 2.2 is a great all around setting, certainly one of the top three but it really excels around water. Something special about the blues.

  • omething special about the blues.

    Yes I currently use it for underwater shots!

  • @Butt Nice beach video, I'm curious how you achieved such a mellow, low-contrast look on a bright sunny day?

  • I had a nightmare with the flow motion v2 patch that I would like to report. I used the patch before at HBR which is 30fps which was fine for me since its better for youtube. It worked, no problems

    then I wanted to try the 24 fps , which I understand it a high quality because its higher bit rate and less compression

    I used a SANDISK ULTRA 30 MB/S 64 GB CLASS 10 Sandisk card, and received the error that went something like "motion picture mode has stopped recording because the card speed is to slow" and none of my clients footage was recorded and it hard to recreate the moment.

    I wanted to use this failsafe patch because I thought it was failsafe, but it didn't work, and now my client pissed,

    should I go back to her 30 fps for less data? another patch?

  • @edubz the 30MB/s Ultra is not so good, get the 30 or 45MB/s Extreme, for me it works very good, and very stable !!!!! Ultra 30MB/s is slower than the Extreme 30MB/s !!! i have tested it.

  • @edubz What Lambo said! FM is extremely stable but does need the mid speed cards of decent quality. That usually means Sandisk Extreme 45mb. I've used Transcend in a pinch but don't have much faith in them.

  • @edubz

    Sandisk Ultra cards fail at very low data rates -- much lower than those typical of FM. These cards are only really suitable for the stock firmware.

  • @edubz Sorry to hear of your disappointment using Flow Motion v2 with a Sandisk Ultra Class 10 SD card. At the time I tested FM2 with Class 10 cards, I was not aware of the Sandisk Ultra cards, and assumed that all cards rated Class 10 by Sandisk were marketed under their Sandisk Extreme product line. From user reviews at Amazon, it appears that unlike the Sandisk Extreme, the Sandisk Ultra's write-speed is significantly slower than its 30MB/sec read-speed. Unfortunately, this indicates that Sandisk Ultra cards will work reliably only with Flow Motion v2's 60Mbps 24L, FH, and H video modes.

    For full compatibility with Flow Motion v2's 100Mbps video modes, I recommend Sandisk Extreme SD cards rated at 30MB/sec and higher.

  • I wanted a 64 GB card, to store more stuff, but is it better, for fragmentation problems to have 2 32 GB cards?

    keep in mind, that I also experienced a nightmare when my sdxc card would not connect to my version of apple os x 10.5.7. And yes, I know that an old OS, but guess what, everything worked on it. It should be noted that in the sticky somewhere about the sdxc os x nightmare, if your not on the newest version of OS X, your sdxc won't be read, because only the newest lion version of os x supports sdxc. 32 GB cards are NOT sdxc right? there for mac os x users who don't want to be forced to upgrade can stay on their stable systems, and still use the failsafe patch.

    There is no patch that will let you work will make sdxc files open on anything other then lion,

    So I was forced to upgraded to lion, which I find no different then 10.5.7, but now some of my logic plugins broke, and crashes logic. But I can open up my files, and I am working, and not all was lost. But I figured that fast action performance would be theoretically be for my class 10 card, but its not.

  • Too bad edubz. Well I've been testing the patch on Transcend 32 GB cards. Was about to buy a SanDisk and the above info saved me some trouble! No problem at 24H until I go over about 4 mins. record time. Then I had experience you described. Camera stopped recording, file inaccessible. Shorter files however worked and imported fine into FCP 7 Log and transfer. My OS is 10.5.8 and I've been reluctant to upgrade for various reasons. I do have to report the continuation of horizontal banding in my fluorescent lit white walls office hallway at various ISO's and WB's and lenses. That was a surprise. Exteriors all looked fine however.

  • Flow Motion v2.02 versus Apocalypse Now - Boom Flat 4s - 24H mode

    The latest version of Apocalypse Now - Boom Flat 4s, uses a GOP-1 all-Intra patch for 1080p24 video (as well as for 25p and 30p video modes). What makes this Intra patch interesting is its 1080p24 quantization Scaling Table. Standard GH2 quantization matrices use finer quantizers for the broad details than are used to encode the more minute details in an image. This technique takes advantage of psycho-visual properties of human vision, allocating larger portions of the encoder's available bitrate to features the eyes are most sensitive to. The Flat 4s matrix used in Apocalypse Now Boom instead takes the radical approach of quantizing all spatial features in an image at the same level of precision. That same matrix is also used for chroma channels as well as for the luma channel.

    Compared to the earlier Apocalypse Now Pseudo-444 Soft matrix by Chris Brandin, the Flat 4s matrix is extremely sharp. Rather than attempting to simulate a 4:4:4 color space, the Flat 4s matrix records all available image data indiscriminately at the finest practical level of quantization. In addition, the GOP-1 setting in this patch encodes all image data in individual I-frames, at a peak bitrate of about 150Mbps. What this means is that Apocalypse Now Boom Flat 4s is one of the purest examples yet of applied brute force - it is designed to record as much data as it can at the highest practical bitrate in each individual frame of the video.

    Flow Motion v2 uses customized Scaling Tables as well. Unlike Flat 4s, the quantization matrices used in FM2 are designed to discriminate between luma and chroma channels, using high-precision quantizers for finely detailed luma data while smoothing the minute details of the chroma data. I optimized it this way because I felt that even with 100Mbps, it was vital not to squander its bitrate on image details that are visually imperceptible.

    Using Stream Parser, we can examine the differences in the encoding properties of the two patches. In the screen shot below, the Flow Motion v2 chart is on the left and the Apocalypse Now Boom Flat 4s chart is on the right:


    Many of the statistics in these charts are similar - the QP and DC columns (which measure peak image quality) are close to the same (and as Chris Brandin explained earlier, DC values below 5 produce no further perceptible improvement in image quality). The differences that stand out are in the Max and Range columns, which indicate the worst case image quality. It can be seen here that Flow Motion v2 permits only a narrow range of QP factors, maintaining consistent image quality within the macroblocks of each frame. Apocalypse Now Boom Flat 4s extends into a much wider range of QP factors, allowing image quality to become very coarse among many of the macroblocks in a frame. Even at 150Mbps peak, there doesn't appear to be enough available bitrate to encode all the details in the Flat 4s matrix at the intended level of image quality.

    Here are unedited 200% crop frame grabs from the two video files analyzed in the above Stream Parser report. Differences in the detailed image quality of the two patches can be seen in the rusted metal mandalas:

  • @LPowell thank LPowell. My settings are Fimmode neutral (natural) -1, -1, 0, -2 - used always been an ND 4 of B & W Germany - shutter allways 100 - The clips are really all out of cam, no color grading - Result: mellow, low-contrast look on a bright sunny day :) - native rendering with Sony Vegas Pro 10 - and thanks again for the great patch - sry for my bad englisch - and: maybe it's the great light here on the Baltic coast ;)
