Timed automatic saves with progessive render?

Post by SABBA » Fri Jan 22, 2010 9:09 pm

I tend to cue up a render and leave work for the evening. Last night there was a power glitch and my machine was off. The render was lost.
I found the "tmp_inprogress_image.png" file but its gamma or exposure was so far off that it took a lot of work in Photoshop to rescue it.
Q: Is there some way to have the file saved at a user set interval to the named file. If not can this be a wish-list item?

If your rendered image is not bigger than your monitor space, there's a workaround:

Use CamStudio, a free screen recorder, and leave it recording your desktop at an extremely low framerate. For example, to capture an image every 10 minutes, set it to "Capture Frames Every 600000 miliseconds". Make sure it captures a keyframe for every frame.

You can later extract images from this video using VLC (another free program).

Hmmm...how do you get rid of the bands formed during progressive rendering....bands formed by number of processors?

the banding dissipates as the render progresses, so typically any temp render worth saving will not be showing any banding... do you have an example?

If you are manually saving a progressive rendering early on, and you want to stop it without the banding, right-click the image in progress and choose "stop before next pass".

On a save yes... there is no problem with saving....it is to do with recording software as it records the screen.

Thanks for the idea Ecuadorian but the images are for print and way to large.
Fletch, if save before next pass is scripted in the software could it be set up to do something like save before next pass every (n) minutes? Also why is the temp render so dark? I can't seem to get a high enough quality image for my use no matter how carefully I manipulate it in photoshop.

the temp render is saved before internal manipulation of final output.
there's no option currently to save before next pass, we can look into it. but the way multithreading works on unbiased may be difficult to implement such a feature.
there's an option to stop before next pass... this is not the same thing.

If you can save temp as HDR you will have far more options in post pro.
