Post by Zitko Josef »

Hello,

Hello Josef

According to Pierre (the developer of XnView), only NConvert (command-line tool) seems to be able to convert 10-bit DPX to 10-bit TIFF, …

No XnView use only 8bits

Comment activer la lecture 10bit du DPX source ?
Je précise que c'est un DPX avec un seul canal en noir et blanc.
Seul NConvert permet de convertir du 10bits DPX en TIFF 10bits

      • 32bits packing
      • LUT 10-bit log => 8-bit linear
    • Write » DPX/Cineon » Parameters
      • Use MSBF order
      • Write DPX in 10bits/component
      • LUT 8-bit linear => 10-bit log

After these comands:
nconvert -out bmp -32bits *.dpx
or
nconvert -out tiff -32bits *.dpx

I created yuv file (yuvit.exe) and then compressed by x265.exe (h.265 hevc). Compressed video is grayscale with green vertical lines. Does anyone know, where is problem? And second problem:

nconvert -out yuv422 *dpx nconvert show: Error: This output isnť possible (not yes implemented)....is it true or bad written comad?

Thank you

Do you mean the available options for processing images using XnConvert or XnView [Classic] or NConvert Josef?

Edit:

If you mean for NConvert, which is possibly most likely reading your previous posts, you can create a text file containg the available options by typing the following at the command prompt:

Code: Select all

nconvert -help > Help.txt
