One thing you could try out is converting your clip with the "Eyeframe" converter and then import the converted clip to your sequence. This usually gets rid of the playback lag as you described it, at least it does so for me.
Here a link to the Eyeframe thread on the Lightworks forum: https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=30817&Itemid=81
Hi,
This sounds like the routing may be incorrect. On the VFX tab selecting the 'Routing' tab and check that the correct tracks are routing to the correct inputs.
Don't forget there is a very helpful Forum of Lightworks users: www.lwks.com/forum If you post the effect and the routing screen grabs there, users will be able to assist.
Hi,
Please make sure you are running the latest version of Lightworks (2021.2) from here: www.lwks.com/downloads
If you are running the latest version and you still get the same error, you can report it to the team here: www.lwks.com/report-a-problem
Hi,
You should be able to import a .PSD file but it will be flattened on import ie, you will not be able to work with the separate layers (if they exist) This file should come in at the predefined length set on the import panel (1 second and up) which you can change. The file can then be added to a sequence and trimmed to make it longer/shorter.
Don't forget there is a dedicated Lightworks Forum: www.lwks.com/forum which has a strong community of users new and experienced to help.
Hmm. What frame rate is your video? This is an old, old post for an old version of Lightworks so may not work, but just in case could try this: https://www.lwks.com/index.php?option=com_kunena&func=view&catid=8&id=80022&Itemid=81#86151
It's been a month with no answers, so I decided to go ahead and ask this same question on the Lightworks forums. And it turns out the moderators over there aren't much for having an open discussion on this topic, as they locked the thread 2 hours after it was opened. There are a few other topics started about the open source controversy, and guess what, all of those got locked too. Here is the post I made about it, if anyone wants to see what was said:
They don't seem much for a civil debate, so I didn't get the chance to ask. But I was wanting to ask them why, in 10 years, EditShare has not clarified the situation. That seems very shady to me, that they would make official announcements about going open source, and then sweep everything under the rug, pretending like they never made that promise. They've had plenty of time to answer, and all they would have to do is explain that their plans have changed if that is the case. Their promise was that Lightworks would go open source after the Mac and Linux version was out, and then it would be open source after that. Now that they have a Mac and Linux version, they won't even address the subject, and that just comes across as very dishonest. At least own up to it. It would be understandable if plans had changed after a certain amount of time. If they tried and it didn't work out, that would be a good enough explanation for me, but based on how they have handled this, I have a feeling that they never had much of an intention to follow through in the first place.
Anyway, what does everyone else think? I was planning on buying the pro version soon, but they've lost my respect at this point.
have the same problem and just wanted to ask this... Have you found a REAL solution yet?
Because, for the love of god, I just can't believe the explantation offered in the lightworks thread that regards this problem and is marked as solved.
the reason for this frustrating problem according to the forums is, that lightworks is out of the box programmed in a way, that it just randomly ads an audio delay in the preview. Thus making the preview function practically utter useless, if you use any kind in your video.
In oder to find out how much frames of audio latency lightworks adds on your system you have to make some kind of test and... I have to stop here because I just can't belive this shit.
I just spend something like 30 hours editing a video to a beat just to find out, that I was not cutting to the actual beat, but to somekind of ghost beat, because lightworks is a FUCKING PIECE OF SHIT.
Btw. here is the forum post explaining the problem:
If you prefer to stick with Lightworks, you can go here and download the Variable Polygon Masks plugin. This will allow you to draw an up to 16 point polygon mask around your subject, effectively erasing everything else. The polygon can also be animated with keyframes in case your subject moves.
​
There is also Davinci Resolve, which I believe has the more advanced matte painting tools you are looking for. I use both but I'm still fairly new to Resolve so I can't offer much help there.
​
Alternatively you can try Natron which has some pretty nifty masking/painting tools, but note that this is a compositing/special effects program, NOT an editor.
A fast processor and a fast hard drive are necessary for video editing, of course. It's possible to import the videos into the Lightworks using the "Transcode" option (when importing). If you do this, then Lightworks will automatically convert your videos into format that MIGHT be easier for your PC to work with. But when you then render the finished movie, you lose some quality because your videos have gone through two conversions (but this does not matter very much if you are just doing some home videos).
Another (advanced) option is to manually convert all your source videos into another format (easier for Lightworks to work with), do all the editing on these converted files, and then, just before the rendering, replace all these converted videos with their ORIGINALS. This is called proxy editing. But this is rather advanced and if you don't do it exactly right you might lose your edits.
I suggest asking advanced users in Lightworks forums: https://www.lwks.com/index.php?option=com_kunena&view=entrypage&func=entrypage&Itemid=81
when you open LW project, are you prompted to do anything about the files whose reference have changed and now appear missing? been a long time since I used LW but I recall the ability to relink to missing files via prompt of some sort.
Maybe carefully look at the waveform of the audio and make sure the peaks are happening when the speech is showing in the video. The playback can have trouble keeping up sometimes, but the timeline will be correct. If you see it being off when on a single frame according to the audio, it's probably the preview that's lagged but corrected by yourself, thus offsetting the final output instead. 720p vs. 1080p shouldn't affect this.
Some people have a method to reduce the source video's quality to make things play back faster/more smoothly, eliminating lag issues. I've not tried it myself, but it might be worth checking out:
While I haven't done this myself, if your sections aren't overlapping, you could make multiple separate edits, then merge them together at the end. This would prevent you from accidentally tripping over previous work.
Here's a link to someone with a related issue that entails multiple edits:
