this is my first projekt with lightworks...
I want to create a kind picture slide show.
At the moment there is only one picture with 60 frames. The picture has the same size as the video. If i try to export, as avi, this 4 sec i got a timeout error.
the only time that I have received that message myself is when exporting to a media drive where the space available was filling up because the exported file size was so large. might not be your problem but just a guess
Save this code to a file called Null.fx in your Lightworks\Effects Templates folder and compile it in Lightworks. You'll have a Null effect in the Colours section. Add this effect to your timeline and see if you can export.
Have you tried khaver's suggested fix, above? If not, do so. Because Lightworks will render the null effect as part of the export process it will correct for any issues with codecs that LW for whatever reason has trouble using in an export.
