so you guys are telling me gripcrop() evaluates and crops every frame? I didn't know this. I'm going to try with some hardcoded bicubic values from FitCD or moviestacker to see if I get a difference in prediction accuracy or CQ.
If gripcrop() happens to hack one frame more then the other compression is going to be all over the place. You may get more comression in the end, but it will be very hard to predict a file size. That is if I'm understanding this correctly. |
ok Phil, you are clear.
see: my new tv don't like overscan2.. show a big black border only on the left,more or less 2 centimeters. can i adjust this changing some values to centre the image? i ask cos i think that overscan 2 give me more compression than overscan 1, don't? thanks. :) |

When you open an .avs file that has GripFit functions, the first call to the filter analyzes a number of random frames, and then it chooses the size, etc. Then on succesive calls after frame 0, it doesn't recalculate frame size at all. It remembers that it's already running, and simply applies the resizing it found on the first run. -kwag |

@ all
see the posts of trillium about gripfit problems: http://www.kvcd.net/forum/viewtopic.php?t=4644 :!: |
We dont have red herrings down here but I think I found one :oops: . Apologies for the distraction. A question is whether asharp and undot filtering the black borders of the source is hopefully transferred to the sampling in a linear way.

GripCrop doesn't take the 5 first frames, it takes tham within the all length of the video. Then it keeps only the "most common values" calculated on this 5 frames. Chances are poor to have 5 frames that are all too dark to find the borders. (This case leads to an error "GripCrop: Auto-detection of borders failed") Quote:

Thanks for a very educational post Dialhot. Obviously I was making a point before about the black frame. I agree that Sansgrip is way to smart :wink:

But of course you can solve the problem with movistacker using bicubicresize insteed of gripcrop. The line to modify is the "Addborder".If Moviestacker suggest you "AddBorders(16,16,16,16)" for instance, juste put "Addborders(12,16,20,16). (parameters for Addborder are left, top, right, bottom). You'll move the picutre slighly on the left. Quote:

ok Phil
:wink: i worked with eletronics(tvs,vk7,dvd,cds..etc) from 30 years and i adjust the width(horizontal) and size(vertical) with extreme precision, right in the bordes of cinescope. i only see this line when i encode using overscan2, the channels,dvds and other sources are perfects. after this adjusts i see a thin line only in this tv(29 Phillips), the others(4) using overscan 2 works fine without black board on the left. thank you for this all, friend! great. :D |
testing again
if i use (overscan2): BicubicResize(448,448,0,0.6,0,0,712,480) AddBorders(16,16,16,16) i see a thin dark grey line on the left :arrow: within(under) the black border on my monitor (using extreme bright). :arrow: load the script and see the video preview in ToK :!: this is what i see in my tv,isn't the border is this "dark grey line". anyone can see this in the video preview? :?: EDITING: was my dvd source, 8O i load from another dvd and the thin "dark grey line" dissapear! incredible! :arrow: using gripfit is perfect :!: :wink: |
