I'm working on my fourth Meister Brau right now and it's 11 AM here- just kidding! :lol:
Hey Kwag, have you tried Lanczos resizer with the LBR template? I'm really blown away by the sharpness of it. Lanczos is built into avisynth 2.06 and is a resizing option in the latest FitCD too :wink: thanks, ren |
Great result, kwag! I'd have a beer right now, if there were any in the house ;).
This might be a little premature, but I'm getting some promising results with 50/48 and scene change detection OFF for this 1h59m movie... |

I just finished sampling with a new technique I'm using (basically the same kinda deal, just slightly more accurate I think) and will know in 3h34m how close it is... By the way, do you know any details on exactly how much overhead there is on a VCD? VCDEasy seems to use a figure of muxed_size + around 11mb for its prediction. |

If my current test proves to be on the money I think I might have come up with an even more accurate way of doing it that shouldn't require an error margin (or, if it does, it should be very small). Basically instead of doing calculations in seconds I'm doing it with frames: Target media = 80 minutes = 836,640,000 bytes Frames in movie = 171,774 Audio size = 114,633,253 bytes Padded audio size = 115,628,333 bytes Sample points = 50 Sample length = 48 frames Frames in sample = 2424 (:?: still don't know how SelectEvery arrives at this figure... it also gives 4848 for 100/48... any ideas? If we can't come up with a formula to duplicate its frame count I'll have to look at the source, or ask dividee ;)) Compensate for overhead: 836,640,000 - 11,534,336 = 825,105,664 Compensate for system stream: 825,105,664 * (2018 / 2048) = 813,019,155 Compensate for audio: 813,019,155 - 115,628,333 = 697,390,822 Final encode size = 697,390,822 bytes Bytes per frame = 4,060 Target sample size = 4,060 * 2424 = 9,841,440 bytes Theoretically this should bring us as close as possible to the correct result. I have a feeling that disabling scene change detection will help a great deal, and might explain why you always get more accurate predictions than me ;). Does anyone see a problem with my theory/math? |
Hi SansGrip and Kwag,
@SansGrip Quote:
@Kwag I have been using the script below and have a question about using multiples of 30 for each hour of movie time (i.e. 2hrs * 30 = 60)? Minority Report is 139 minutes or 2 hours 19 minutes. I see some scripts using 50????? What's the rule and are you still trying to determine the factor being used (i.e. 0.95, 0.98, 0.95555, etc.) LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\MPEG2DEC\MPEG2DEC.dll") LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\BlockBuster\BlockBuster.dll") LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\LegalClip\LegalClip.dll") mpeg2source("D:\Temp\movie.d2v") # IL = Framecount / 60 SL = round(Framerate) * 2 SelectRangeEvery(IL, SL) # LegalClip() LanczosResize(496,448) Blockbuster( method="noise", detail_min=1, detail_max=10, variance=1, seed=1 ) AddBorders(16,16,16,16) LegalClip() -black prince |
Hey SansGrip,
Just did a test file prediction using Tmpgenc's Clip Frame. The test file size using Clip Frame is 18,483,997 and without 20,305,188. I believe you felt there should be no significant decrease in file size just by masking borders. This shows a 2MB decrease with no change in picture quality. What could be happening during Tmpgenc's mask that accounts for this decrease :? -black prince |

Edit: I'm glad you brought this up again. I really want to thrash this out, because that's a serious gain in compressibility... |

view this script with Tmpgenc Clip Frame the borders for masking seem correct for the aspect ratio from FitCD (16,16,16,16) or TV-overscan #2. :) -black prince |

The results are in :). Untouchables, 1h59m, new GOP, no scene-change detection, 50/48.
Target file size of video: 706,804kb Actual size of video: 697,068kb Difference: 9,736kb = 1.39% Not bad -- looks like I can go ahead and code this new method up and then play a little more with the sample points/sample length settings... |
