Recently I did a lot of direct MPEG-4 exporting with the pro version.
With 720p exports everything went fine, but when I tried to export 1080p25 video, after several minutes of rendering Lightworks just quit.

As it seems, today I could find the cause for that and hopefully solve it:
I always render to some external media, in order to save render time. But still, as it seems somehow the local disk C: where my Lightworks is installed is used for caching the video stream during export.
I noticed that from my 80 GB disk less than 4 were still free. So I cleaned some stuff in order to have around 30 GB free and rebooted.
And voila, my full HD rendering is running, at least until now (around 07:50:00 hours out of initially 08:15:00 remaining).

Thought that might be usefuly to some of you guys: Keep an eye on your (system) disk space (or where Lightworks is installed?), otherwise you might see your rendering process saying good-bye

Of course the interesting question remains, does Lightworks do the caching, or QuickTime, or Windows?
And then it would be interesting to know which location is being used for that, it might need some cleanup once in a while as well.

Edit: It cannot be my page file since I switched of VM completely.

well I have a different issue now on that

The rendering runs until the end, after more than 8 hours of doing stuff an error message is dropped out of Lightworks 'unknown error', and after confirming that there is no any file at my output location.

I will check Lightworks log in the afternoon or during the weekend, along with some testing of a shorter part of the movie

As soon as I have some news on that I will of course let you know.

Unfortunately all my efforts still did not lead to a good end.
The problem is:
As long as I just use some short clip sequence of this project for rendering, regardless if 720p25 or 1080p25 is used, everything works like a charm.
However, as soon as I try to render the entire edit (with a target size of about 4 GB) at the end of the rendering process Lightworks gives me the message 'Unknown error' at the rendering window, and the entire target file gets deleted.

Currently I am trying something else by using the BD export resulting in an MTS file, we'll see after another 3 hours if that will work.

Since it is very annoying being unable to export this about 1 hour long edit to MPEG-4 HD with the Lightworks pro version, I really hope that somebody here can help me out of this pain.

Could it be a FAT32 problem. I once tried to render a project to an external HD and right at reaching 4 GB the process stopped. In my case it was the limitation that the FAT32 HD. With the internal HD it worked propperly.

Hi muellehe,

that is indeed a good hint.

However, why does it work with one and the same FAT32 disk, in combination with the BD export option then?
The resulting file is more than 12 GB in size.

Maybe a matter of the different file handling at both export options...

Sorry, I am for sure the last person to be able to tell you. I just by chance faced a problem with exporting files larger than 4 GB. (www.lwks.com/index.php?option=com_kunena&func=view&catid=70&id=42943&Itemid=81) I'm afraid somebody else has to figure out the technical background of your problem.

Hi muellehe once more,

thanks again for the link.
I will give it a try with NTFS these days and the MPEG-4 export, just have to make a drive empty and then format it.

Would be kind of 'funny' if it would be like that, seeing that with BD it already works with much bigger files on FAT32.
Anyway I will try that and keep you posted.

OK guys, test with a NTFS formatted drive also leads to the same 'Unknown error'.

So IMHO something must be wrong particularly with the MPEG-4 export function, since exporting with BD works like a charm.
