My 580 GTX is the PNY "Enthusiast Edition" and according to the device manager the driver version is "188.8.131.5209" which corresponds to the 260.xx series if I am not mistaken. Â I just checked and NVidia has recently released the 265 series of drivers which improves performance on a number of games. Â I am now downloading driver 266.58.
The issues I describe only have a detrimental effect when attempting to save as an MP4. Â I have experienced several issues when rendering:
1. Â The saved movie is nothing more than a green screen the length of the clip. Â In the past, this has been preceded by The sky turning black after the movie has begun to render (described in a previous post.)
2. Â The saved movie has the effect of a "negative" or inverse where the sky is green and the grass is pink. Â This has occured on the beginning of a long clip (1:00) and on the whole of a short clip (0:10). Â I may still have one of these clips saved; I'll check and send it your way.
3. Â The rendering window turns white when first saving a file. Â This has occured when saving as an MP4 and as an image sequence. Â If it happens when saving to MP4, I press ESC to stop the saving (I don't want to wait to find out that the movie didn't save.) Â If it happens when saving as an image sequence, I have a second monitor which has open the folder where the files are being saved. Â I can see the images populating the folder as the render continues, so I don't press ESC. Â Eventually the white screen goes away and the viewer returns to normal.
Of note: Â The white screen also occurs when opening a heavy scene and then disappears as the Lumion workspace comes into view.
I have stopped trying to render a movie directly to MP4, and now use several other programs to convert the image sequence to MP4. Â Which is actually fine since I have more control over the end result.
