Tiff export problem with Nuke

Salut à vous,

j'ai des soucis d'exportation sous Nuke en Tiff 16 Bits
je dois sortir du Tiff 16 Bits 4K non compressé qui pèse dans les 50 Mb normalement

mais Nuke me plante le rendu si je choisis "none" dans compression tiff
il me dit qu'il y a une erreur a une certaine ligne
et il me calcule des images de 1 Kb si je choisis "PackBits" ou "delfate"
ca ne marche qu'avec "LZW" mais mes images ne pesent alors que 17 Mb

des idees ??

merci par avance

Hi,

I've got a export problem with Nuke
I have to export TIFF 16 Bits uncompressed 4 K which generally is a 50 Mb file

But Nuke crash the render if I choose "none" in the tiff compression window
He told me that there's an error at a certain line
if I choose "PackBits" or "Deflate", the render files are only 1 Kb !!
the only way to have my tiff is to choose "LZW" but my files are 17 Mb only

Anyone can help me please ??

Thanks in advance

Hi Vincent,

Nuke is very buggy when it comes to TIFF output. Which version are you using?

When it comes to > 8-bit images, I recommend using EXR for which Nuke has excellent support. Even with 16-bit half-float, you get lots of more information per pixel than with 16-bit integer as in TIFF. And it has quiet a few compression schemes as well...

If you absolutely positively have to go with TIFF, export EXRs and use a command-line based converter for example imagemagick http://www.imagemagick.org/script/index.php to get them into the desired TIFF format...

Cheers,
