There might be different reasons, why this happens:
1.) Some virus scanner or security setting on your computer might stall the communication between LRTimelapse and the Adobe DNG Converter which will be used for preview generation
2.) The images cannot be loaded or processed fast enought, this might happen because of a slow harddrive or network drive for example.
To troubleshoot the issue:
- Make sure to have installed the latest version of Adobe DNG Converter: https://lrtimelapse.com/install/
- Make sure nothing is blocking on your computer. Whitelist LRTimelapse and Adobe DNG Converter in your virus scanner
- On Windows: make sure you have not more than one virus scanner running. Usually the built in Windows Defender is the best and fastest option anyway. Put the folder C:\Program Files\LRTimelapse 6 in the white list of the scanner.
- On mac: allow full disc access, to prevent the OS from blocking any access, see: https://forum.lrtimelapse.com/Thread-wil...-and-later
- Make sure your timelapse sequences are located on a fast drive (an internal ssd would be best). External harddrives might be too slow, the same goes for regular network storage. I'd recommend at least 5Gbit Ethernet connection and a NAS that is fast enough, if you want to work directly on a network drive.
- If all of this doesn't help, reduce the number of parallel threads for Visual Preview generation in LRTimelapse's settings/Expert settings. Set it to half the value and see if that helps. You can experiment with the value and see which one will get you consistent results. If this is the issue, you might also need to reduce the other setting for number of parallel threads for internal export.
Also: the more parallel threads you use, the faster your drives must be able to deliver the images.
