Hi SubJunk,
As you might have read in my postings I m pretty new with PC frame interpolation and unfortunately I m a little noobish too as it comes to PC. Well, I ll try to explain you what I want and maybe you can tell me if it s possible: After doing a lot of reading and questions on the SVP forum I finally tried (the lastest) version of SVP last night. I choose the Core2Quad profile because I have a Core2Quad and changed one of the settings in SVP from 'x2' to display refresh rate (which I put on 60Hz in my case because that s the max of my digital projector). I got a CPU load of 70%. I played a movie and it runned 'fine'. With this I mean that I only had problems with frame drops reported by madVR (but that s for later; first things first). I did however noticed artifacts which bothered me a lot (especially around the contours of people who move). So I switched to 'expert' view in the SVP manager which gave me a lot of options to fine tune. Changing one of the options (don t remember what option it was) from 'normal' to 'complex' helped some but also raised my CPU a bit. After this I tried to change more of the settings in the expert view to a higher quality setting but soon the max of my CPU was reached. I now know for sure that my CPU is just not capable of handling ALL the highest settings in SVP. I m not going to invest in a new systeem (i7 970) only for SVP so what I want to try is CONVERT my movies with the help of you guide. But I already have some questions about it before I start trying this: 1. Is your guide compatible with full Blu-Ray rips in BDMV folder structure, .m2ts Blu-Ray remuxes, .mkv 1080p content (BR rips that are decoded to save space) and .mov HD trailers? 2. Is it possible with you guide to convert a movie with the highest possible settings that are in theory possible with SVP in real-time? (btw. cannot imagine there s a PC out there that can handle ALL the highest settings in SVP in real-time for 1080p content) my hardware: Core2Quad Q9450 4gb DDR3 1333 MSI GTX460 Cyclone 1gb ddr5 OC overclocked @880mhz 1000watt power supply JVC RS25 Dila projector 1920x1080@60Hz max. my software: NVIDIA 285.62 MPC-HC 1.5.3.3757 madVR v0.77 as video renderer LAV Filters 0.38 with CUVID (hardware decoding) enabled Last edited by THX-UltraII; 4th November 2011 at 14:10. |

Well the "highest" settings in SVP will often make the quality worse, because SVP does not sort its settings in order of worst to best, they are just options to choose. But yes, many PCs are capable of running the highest quality settings (the default tuning in InterFrame) on 1080p in realtime. |

Ok, thanks SubJunk.
So I started last night with your guide but I immediately have some questions already @step 1 - with the updates process of MeGUI I get a notification that 'neroaacence' is outdated and that I have to dl this from the site from Nero and unpack it to the correct path. Is this step need for the coversion I m going to do? - I don t know what to do exactly with the step 'Close MeGUI and extract the tools folder over the top of your MeGUI tools folder, which for most people will be C:\Program Files\MeGUI\tools\.' EDIT: I think I found what the pupose it of the tools folder. I just copied and pasted the 'tools' folder that was located in the folder 'Files-20111103' I just downloaded and pasted this into my folder 'C:\Program Files (x86)\MeGUI\tools' (I did overwrite the previous 'avisynth_plugin' folder). After this I went on with your guide in the hope I don t need the nero thing to download. Ok, everything went well untill step 7 where I have some question about: - I own a Q9450 with 4 threads so I filled in 2,7 at SetMTMode correct? - I own a fairly good video card, the MSI GTX460 GDDR5 oc edition overclocked@900Mhz. I read that I can increase the speed of the conversion by adding a line to the script. But I see that it will take slight picture quality so when I want the highest possible quality I just don t fill in this line even though a have a good video card correct? (never thought that a videocard could help with a conversion process btw) step 8: the checkbox 'prefer DSS2 over DirectShowSource' is greyed out and not selectable. And if I already own LAV filters and all my video content runs good with this atm, can I skip the codec package download? Enough questions for now I think . I ll wait for further instructions before I move on now. Last edited by THX-UltraII; 5th November 2011 at 12:55. |

Hi THX-UltraII, I don't think this is the right place to discuss this so please ask further questions about the guide by commenting on the guide. I'll answer this lot of questions here for convenience, though

Sure, you can always install codecs at a later stage if you run into problems too |

Hey SubJunk, I asked about GPU encoding before, however, I have some new questions. Now my GPU vs CPU seems to be 180 FPS vs 210 FPS or so. My GTX 570 has 480 CUDA cores, each running at 1.4 GHz. I'm not good at math, but I've also heard that CUDA is much faster than regular CPU encoding because you've got 480 slower cores versus 8 high speed CPU cores. Not sure if your script uses just the graphics card, or whether it actually uses the CUDA cores.
Here's a video to show you what I'm talking about Okay this guy isn't doing video encoding, but he basically bought a bunch of GPUs and is crunching some serious numbers with it. Same could be applied here, although I've never tested it out before. Long story short, would it be better to upgrade one of my old computers with another i7 2600K? Or do what this guy is doing. Wouldn't need to upgrade the whole computer, just the CPU, motherboard, and RAM. Another thing I wanted to add was when the GPU=true, my GTX 570's load is only around 10%. Is there a way to utilize the whole card? Last edited by magnetite; 6th November 2011 at 09:14. |

@magnetite Hey, I'm new here but I've been working on this with Sub for years before he moved here. GPU=true does not completely turn everything to the GPU. It just spreads the work across. Your CPU will still be pegged full. You cannot compare this to CUDA computing. I use InterFrame with realtime playback. Cuda and GPU computing is way faster than CPU but only when the app is properly written to address everything the GPU has to offer. I don't under stand why your GPU rendering speed is slower though try and get that sorted. Are you using SetMTMode?
Personally I'd love to see a completely separate GPU, CPU utilisation. Eg the CPU does the interpolation and the GPU does the rendering or vice versa. Don't see it happening soon though Last edited by widezu69; 6th November 2011 at 21:15. |

I know it only takes about 20 minutes to do an episode, but I'm actually doing my whole library like this so I'll take all the speed boosts I can get. Last edited by magnetite; 6th November 2011 at 23:02. |

Actually, try (2,15) I find that slightly better. Ok so your GPU mode has increased speed. There was some confusion there good to see that you have a nice machine and are using it well.
@Sub, how much difference to the quality does dct add? I'm realtiming your second highest settings and was wondering how much of a noticeable difference it actually adds. BTW I'm playing everything @120fps -> 24x5 |

I guess I was just throwing it out as an idea of what could be accomplished with this someday. |

Hi SubJunk, first of all I want to make the compliments for the script, I'm using it very often and I hope there will be more improvements regarding moving scenes.
I just need some advice about the encoding process: usually I use 2pass at 3000kbps for 720p source at 24fps so how much you suggest to set the bitrate for the same "interframed" source? Someone says that would be enough a 20% more of the usual bitrate (in this case 3500/4000kbps) or do you think that will be neccessary to doubling the bitrate too? |

If you use x264 I recommend using CRF instead of setting a bitrate. It will adjust the bitrate for you based on the CRF value and it takes into account framerate in recent x264 versions. Personally I use CRF 14 for near-lossless quality, but release groups are using values around 20. |

I'm not sure, but you can do an easy test to find out yourself:
1) Encode a video using CRF at its original framerate 2) Encode the same video using the same CRF value but using InterFrame 3) Calculate the difference between the two filesizes |

How do you measure this? Programs? When I do framedoubling realtime I can only measure that video skips frames at 60fps or not (reading output framerate of my videoplayer).. but I wonder if I have more headroom to increase script settings Last edited by travolter; 17th November 2011 at 10:28. |
