That's a new issue, isn't it. We discussed crashes when exporting so far, not missing sound in exported file.

Yeah, initially the exporting process was causing my machine to crash and I was having to force restart it to fix it.

Now thanks to 14.5 it's exporting fine, but with no audio.

It did, however, export fine with sound when I did the 2min test clip, but that was a fresh project. The one that keeps exporting without sound was a project I started working on in V14.

Under normal conditions, if sound is audible in preview, Lightworks exports sound. That's highly reliable. The most common problem reported on the forum when sound isn't audible in exported files is that something's wrong with settings of media players or audio device.

I'd suggest considering to start a new project with V14.5.

So I started a new project today. Worked on it all morning.

After exporting around a fifth of the final video, it crashed my PC again. My second monitor loses connecttion and my main monitor stays connected but turns black.

I'm going to try and leave it for 1 hour and a half and see what happens

So I left my pc to do its thing. It randomly restarted itself after leaving it for nearly 1 hour and half. I'm using V14.5.

I'm now going to try and just export the video with all the effects and such, and then re-add it to lightworks and work on the music.

What you tell sounds more and more like trouble with your computer (drivers, hardware).

I'm not aware of anybody else with the bunch of problems you describe in this combination.

What I would do if I had your problem is converting all media (video, audio and images). prior to import, just to exclude problems caused by damaged files - the video material either with Eyeframe Converter to MPEG2- IFrame HD or to AVC with Handbrake, audio with Audacity to WAV and images to PNG or JPG with Photoshop.

If the trouble is caused by your computer it won't stop.

As suggested, you must exclude material problems first, before starting to search for trouble with your computer.

Me too - on 2 different laptops (windows 10). Latest stable version of Lightworks.

Welcome to the forum.

Please could you provide the specification of your computers.

Thanks for your response.
I suspect it's the mp4 files causing this.

Lightworks versions:
Lenovo: Lightworks2020.1 Beta (118883) Dec 17 2019)
Samsung: Lightworks2020.1 (122068) May 18 2020

Exporting to MP4 (I'm using the free version) takes over 2 hours for a 50 minute sequence, and while it's doing it the screen goes black, and the mouse and keyboard don't function. The pc's recover when the export has finished

I've been ok with other projects.

Full system information available if you need it - around 1.8MB's each

Media info also attached.

Both of those are low powered for video editing, What type of video files were you editing?

Please see media info added to my previous post.

The editing works fine with these laptops (I use the Samsung), especially if I make proxy's. It's just exporting sequences using these mp4's, which were both made by Zoom.

Thanks for your help.

The current release of Lightworks is 2020.1.1 from 22 September 2020. I'm not sure if updating will fix your stability problems, but as a matter of interest, what are your reasons for running one outdated unstable release on one system and an outdated release on the other?

I don't use the Lenovo - I just used it to check that a Lightworks archive would work on another pc. I hadn't realised the stable version of Lightworks had been superseded - I'll update as soon as Microsoft have finished using my laptop
I spent years using Adobe Premiere and Pinnacle capture card and software, with Windows ME and XP computers (I had to make showreels), so using Lightworks on a low powered laptop is a DREAM! As a director (tv - retired) I've worked many times with editors using Lightworks, but never took any notice of how they worked their magic (just the results). The routing screen is something I've seen many times - fun to actually use it.
