Autocrop.dll usage

[juGGaKNot]

I just want autocrop to crop the the nearest x16 resolution, not to cut anything else

right now i use

AutoCrop(3,16,16)

But if the clip is too dark it will cut too much

for ex : 1184x666 ( what i use ) mod16 must be cropped to 1184x656 ( nearest resolution ) but if the frame is too dark it will cut way more

how can i fix this, reading the documentation i think

AutoCrop(3,16,16,0,0,0,0,10,25,50,500,-0)

might do it but i am not sure, what should i use ?

The purpose of AutoCrop is to detect 'black bars' and crop accordingly. If you already know that you want to crop to 1184x656, why not just use Crop?

Or to save yourself the calculation, write a simple function that works out the nearest multiple of 16 (f(x) = x/16*16) and use that with Crop.

Using AutoCrop for this is an unnecessary overhead, but if you really want to, it might work (I haven't tried it) with
AutoCrop(3, 16, 16, threshold=0, samples=1)

people will use it with other resolutions

k i will try and post, thnx

i should try on a complete black sample right ?

yes setting the threshold to 0 makes it cut only what is needed, in my case mod 16

AVIsource("C:\x264\movie.avi")
ConvertToYV12(matrix="PC.601")
LoadPlugin("C:\x264\bin\autocrop.dll")
AutoCrop(0, 16, 16, threshold=0)

uncompressed full black avi

Have you put any thought into resizing to the nearest mod16 resolution vs cropping?

spline64resize(16*(width/16),16*(height/16))

I just need to figure out how to automate addborders() to get to Blu-ray resolutions, i.e. 1280x720 and 1920x1080.

no way resize.

Sorry this makes no sense to me.

the avchd coder maker has his own app for this, see avchd coder.
