Problem saving 16bit tiff file using RGB format

[MonoS]

Hi, i'm trying to save some image in a 16bit tiff file after some postprocessing using vs.

this is the script

import vapoursynth as vs

core = vs.get_core()

src = core.d2v.Source("D:/Download/VTS_04_1.d2v", nocrop=False).std.Trim(0,0)

crop = core.std.CropRel(src, 72, 72, 60, 60)
crop = core.fmtc.bitdepth(crop, bits=16)

up = core.nnedi3.nnedi3_rpow2(crop, 4, correct_shift=True, nsize=3, nns=4, qual=2)

res = core.fmtc.resample(up, 630,456, kernel="Spline64", css="444")

conv = core.fmtc.matrix(res, mat="601", fulls=False, fulld=True, csp=vs.RGB48)

#fin = core.fmtc.bitdepth(conv, bits=8, dmode=7,fulls=True, fulld=True)

conv.set_output()


While waiting for the correct version of imwri, i tried saving images using ffmpeg [and also imagemagick]

I used this

vspipe.exe file.vpy - | ffmpeg.exe -f rawvideo -pix_fmt rgb48 -s 630x456 -i - test.tiff


The output image is this one http://www.mediafire.com/view/mhuzt98u7nc8uht/incorrect.tiff
The same thing happen with rgb24.

Instead if i don't convert to rgb and pass the yuv44416 stream to ffmpeg it output the correct image [ http://www.mediafire.com/view/th7sjgao5rxhp85/correct.tiff ] but give me some warning on swscaler and about chroma interpolation.

What could be the problem??

With this script, the output of vspipe is planar RGB. ffmpeg's "rgb48" format is packed.

Try "-pix_fmt gbrp16le" and


conv = core.std.ShufflePlanes(clips=conv, planes=[1,2,0], colorfamily=vs.RGB)


before set_output().

Ok, now it works :D [but still give me the warning about chroma interpolation, that AFAIK i shouldn't care]

Thank you jackoneill
