Digital Light & Color

To view images on a tv-set I made the following workflow: resize image (bounding rectangle, to fit the width or height of the tv-screen), change color profile from Adobe-RGB to sRGB, save as jpeg 95% quality.
I used an identical workflow in the past on my previous pc; that pc had a 2 core processor but PWPro recognized only 1 core, so only 1 core was used. Always worked fine. W-XP, 32 bit.
I got a new pc, 6 core AMD processor, Windows 7, PWPro 64 bit. All cores are found by PWPro, all images are processed very fast. But only about 20% of the images are saved, although all images are processed o.k. according to the message after the completion of the workflow. If I change the number of cores in the workflow preferences to 2, 50% of the images are saved. If I use only 1 core, all images are saved.
I was wondering if the processing might be too fast for writing to the hard disk. Windows and my applications are installed on an SSD, so I tried to save to the SSD, but with no different result.
Anyone else with similar experiences? Am I doing something stupid?

Make sure you are not using sequence numbers in your Save File widget. Sequence numbers can only be used with a single core. Using them with multiple cores can result in files overwriting each other.

Hi, Kiril
When I use the Save widget in a workflow, while wanting to rename image files in sequence like that, they don’t renumber correctly, but like below. It’s especially painful when there are several hundreds images….
I tested your councils above, but the result is identical.
PWP 32 v6.0.10 is running on a PC with Intel Core i7 950 (4 cores) under Window7.
Where is my error?

Thanks Kiril,
I indeed used sequence numbers. Problem solved.

I assume that the next issue, described by Artifex, has the same cause. The ... [1], ...[2] file names are generated because "Generate unique name" is selected while using sequence numbers.

Just to be clear, if you want to use sequence numbers, make sure that Do not multitask is checked. The Do not multitask option is located under the File button in the Workflow pane.

This setting is saved when you save the workflow.

Thanks Kiril, now that functions perfectly.
