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, …
[color=green]nconvert.exe -help[/color] wrote:Code: Select all
Options :
-ilut file : Input LUT file (DPX/Cineon)
-olut file : Output LUT file (DPX/Cineon)
… but not to YUV with 4:2:0 chroma subsampling.
[color=green]nconvert.exe -help[/color] wrote:Code: Select all
Available format:
Name Write Description
[yuv411 ] : YUV 4:1:1
[yuv422 ] : YUV 4:2:2
[yuv444 ] : YUV 4:4:4
XnView comes with 2 LUT files (
8to10log.lut +
10logto8.lut).
- Tools » Options... » Read/Write
- Read » DPX/Cineon » Parameters
- 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

Sorry, but I have one more question. Where can I see all usable processes of the xconvert On your web is screenshot, but User cannot see all processes.
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:
