Twixtor enables you to speed up, slow down or frame rate convert1 your image sequences with visually stunning results. In order to achieve its unparalleled image quality, Twixtor synthesizes unique new frames by warping and interpolating frames of the original sequence... employing RE:Vision's proprietary tracking technology that calculates motion for each individual pixel.

New in V6: Twixtor 6 now has GPU support for Adobe After Effects, Adobe Premiere Pro and Apple Final Cut Pro.

Internal calculation speedups of up to 5x on GPUs have been measured over running Twixtor in CPU mode, already known for its speed. Speedups of this magnitude are usually seen with higher end cards such as the AMD FirePro W7000-9000, Radeon HD 7970 or 7990 or NVIDIA Quadro K5000, K6000 and GeForce GTX 680, 690, 780 and Titan. Note that most currently-sold GPUs will provide customers with needed acceleration, including many mobile GPUs for laptops.

As a total user experience that includes reading frames, processing with Twixtor and writing frames to disk, we have measured speedups of up to 5x in After Effects, and in Premiere Pro and Final Cut Pro we have measured total user experience speedups of up to 3x. Of course, the total speedup end-users will see will vary once application overhead is taken into account: this includes disk I/O, internal host buffering schemes, bandwidth of PCIe bus, codec used for footage, etc.

Users are advised that their specific speedups are dependent on system configuration, specific GPU, and features of Twixtor that are used. Customers who have used Twixtor 5 should test the demo to make sure they will see the speedups they desire before upgrading to Twixtor 6.

Once again I am pondering a decision to which I would like to inquire on this forum's awesome knowledge of all things GHack2 related.

So what is this all about? You see, I am in pre-production for a no budget webseries called JÄSØN (http://creativemonkeys.org/jason/), a satire about a failing wannabe serial killer klutz. The style I am going for is grimy dark and dusky narrative. A lot of Se7en and 8mm. The first episode has a long low steadicam shot going through several rooms of Jäsøn's trashy apartment, showcasing his failed and broken life. There are moments of serenity, when light breaks through barred windows and plays with dust in its path, there are many dark corners and an overall low saturated, mid/hard contrast range and a wicked eeriness I want to achieve. Then there is a low light scene in a bathroom with flickering fluorescence light, and one ultra slow motion moment.

Our DoP will light it properly, I have no doubts, but I would like to have the proper Hack for the right shot prepared. I thought about getting a couple of cheap and slow SD cards and store different hacks on them and use them on set as we need them.

But here is my problem: My DoP is not familiar with the GH2 - he has a 5D MKII he suggested to use, but I think the GH2 has a nicer film look - and I want to make it as easy for him as I can, by having the best settings ready. And since I am not so good with cameras to understand the finer details as much as many of you do. This is why I am turning to you for help.

I need a set of 3-5 hacks that I can swap on set when needed, to accomplish the best shots. The premises are:

Best Quality - The best possible image quality. Is 2k HD MotionJPG an option? Any other suggestion? Film Look - as close to narrative cinema (80/90ies) as possible. I am considering to use anamorphic lenses here and there, so that should work too. Slow Motion and Ultra Slow Motion - I don't mind using 720p and upscale it later for those shots. How much difference is GOP1 and GOP3. Good Low Light - I do have light, so I am not too worried about low light situations, but I might want a shot were we deliberately do not use any light and for that, I would like to be prepared. Equal Quality/Equal Style - All the hacks need to work and/or work together flawlessly. 25FPS - Living in Europe, I have to adjust to the 50Hz issue. This is why I am opting for 25FPS, but IIRC it should work just as well with 24FPS as long as the shutter is set to 50/100 etc. right? [Edit] Greenscreen - For some effect shots, we will use a greenscreen and a good setting for that, to preserve as much color and details as possible, would be great too.

I am looking forward to your suggestions (including in-camera settings, workflow etc.) and thankful for your help.

PS: I forgot to mention: I have a 64GB 45MB/s SanDisc Ultra and currently no budget to buy the 95MB/s version, as I have to put the few bucks I have into other things, but spanning is irrelevant for me, as there are no shots that should be longer than 3-4 minutes. Thoughts?
