Comment (by solidghost):

 Hello Again. Im still having trouble opening the Raw-file correct. I can
 open it in ffplay. But I dont know if I can zoom there.

 I tried your command:
 {{{
 ffmpeg -i SD_PAL_Uncompressed_10bit.mov -qscale 2 -dc 11 out.m2v
 }}}

 And it also produced the artefacts. You need to zoom in 400-800% to really
 see them. But when you do, you will see that they are very systematic. I
 only managed to open the m2v-file in Adobe products, Adobe After Effects,
 Adobe Premiere & Adobe Photoshop. If you don't have any of them you can
 also...

 1. Open the m2v-file in VLC
 2. Zoom to the maximum
 3. Take a print screen
 4. Open that picture in your picture viewer.
 5. Zoom in the picture viewer a lot.

 Remember to zoom into the grey solid colour ( Coulumn ) to the right.
