i have been working on a project using .dpx files.
sometimes when i come to render out the finished composite it goes through the motions, but does not write any dpx files to the drive.
it happens even after i have already rendered the comp out before as a dpx file and have not made any changes to it. it just seems to not like doing dpx files.
once this has happened, it does not seem to be able to render as dpx again from the project. i can render out all the other file formats and have been substituting cineon files for the dpx ones.
if i then import the cineon files back in and render out as a dpx file. it renders out ok.
anyone else experienced this?
Mark.
what version of shake are you using?
apple mac osx. using shake 3.5.
also we are having problems when adding a layer of text to a dpx sequence that has been converted from a logarithmic colour space to a linear colour space. if you link directly from the log/lin node to a lin/log node there is no change in look, if you add a layer of text or graphic file it makes the white all mushy when you look at the converted file.
any ideas?
You should work in float or tweak your loglin white and black values to avoid clipping (you can use a histogram to see how far you should go with your white and black values).
The reason you're noticing that clipping on whites if you add an addtext node is you're braking concatenation between log2lin and lin2log.
