Moved this to Screen Capture section of forum where it will receive more attention - Moderator.

Very new to using Lightworks and having some issues exporting my editing files.
Not sure all the data you guys need but here you go...
GPU- Nvidia Geforce GTX780
CPU- Intel Core i7-4790K
Ram- 16384MB
Windows 7
Disk- 900GB 700 free
Lightworks Pro

Export
Format - WMV
1080p 59.94fps
VC1
48KHA
16bit
embedded
Finished work duration 7:55:42.19

I realize that it is huge , but I don't believe that is the issue. Source video/audio is gameplay from shadowplay. First time exporting it froze on a particular segment so I restarted export. Froze at exact same spot. All source video/audio is recorded in exactly same format. So Second time I edited out of few frames and it easily worked . Export has reached another spot where it hangs up. I get no error message except "failed". So this time I took out the segment completely and edited the segment back in from the original source. Still failed at that segment. I tried editing a few frames out but it looks like I will have to take more of the video out then I want too. Before I have to go and replay this game sequence and record and edit all over again, is there something I have set wrong or can change that might fix this issue?

Sorry for the newb questions. I've read through the forums and realize I shouldn't have made one huge file but it's too late for that. I need to see if there is a way to salvage what I have done or am I stuck redoing this project from scratch.
If there is any more information you need , that I haven't provided - pls let me know. Sorry if my explanations are disjointed but I am the frustration breaking point right now. Thanks for any help.

Welcome to the forum.

More information is needed to troubleshoot this problem. Please read this post and supply a MediaInfo report of the imported files.

Screen capture software often creates footage with variable frame rates that are not compatible with professional video editors that require a constant frame rate. Please post the MediaInfo report in this thread which may confirm this.

You may need to convert the files to constant frame rates with something like Cliptoolz Convert or Eyeframe Converter.

That's something that causes a variety of problems.

I see you are also exporting to WMV. I wouldn't, unless you need that.

Going to try AVI and see if it still fails.

It may result that you will have to resolve the variable frame rate issue before you import to Lightworks. Since you will be required to decode the source material (in order to force a constant frame rate), it would be good practice to transcode the material to an edit friendly format. I consider prores to be a good codec to use. The issue then becomes one of storage requirements. Eight hours of 1920x1080p 60 fps is going to take something short of 500 GB of storage. If you were to decode, enforce constant frame rate, and encode to a compressed format, you will save storage space. However, there will be a reduction in the quality of the video because of transcoding from a compressed format to a compressed format.

Running it AVI or MP4 did fix the issue. It is halfway done now and no fails. THX!
