Hy Gunter, I've found a bug on LRT4 pro.
Sometimes, visual preview is not working.
When I click on visual preview button a yellow line appears a the bottom of the preview windows , some "adobe DNG converters" icons appears on my menu bar but visual luminosity columns still stay empty and no pink curve appears.
No visual correction are applied on preview windows and visual deflicker button remain grey...

Here a screen shot
   

Do you know what to do ?

Thanks !

Is this happening on only some sequences? Did a restart help? Could you please send me the log file (info menu/log) after this happened.

same is happening to me, and I have a deadline of EOD to get this exported. because the visual preview doesnt work the deflicker I cant use either.

And then in basic the deflicker doesnt work at all!!!

Please HELPPPPPP

Do you have the latest Adobe DNG Converter installed? See http://lrtimelapse.com/install

If so and the problems persist, I'll need the log file: info menu/log after trying to load the visual previews for a sequence where it doesn't work.

Here a log files. DNG converter is 9.0 mac

I've tried many things.
Frist I install new version of LRT 4.02 but the problem still remains.
I've tried to convert RAW CR2 files to DNG with DNG converter ,
I've tried to convert RAW CR2 files to DNG from lightroom
but visual previews still don't work.

I don't understand why...

This is indeed strange. Please try renaming the folder where you have your images inside:
"mont d'or 06" - try removing the ' - just call it "mont dor 06" - you can rename in LRTimelapse with right click on the folder. Try, if that helps.

Yeeees it's OK !!
I don't understand why other folders with similar name don't need renaming but it's ok now with "mont d or 06"..!!

Thanks !

I had a similar problem - maybe Gunther will report further, but it seems that some characters in the file path can cause problems. In my case - and probably yours - it is the apostrophe character (').

In my case, a folder was named "Long's Peak". In your case, "mont d'or".

This appears to cause Visual Previews to fail. Not sure if this is something that can be fixed in LRT or if it is a DNG converter issue.

Regards,
Mark
