Lightworks: The professional editor for everyone - Forum Kunena Site Syndication Fri, 03 Jul 2015 10:35:44 +0000 Kunena 1.6 Lightworks: The professional editor for everyone - Forum en-gb How to import magicYUV .avi clips into lightworks - by:
I tried importing these files directly into lightworks, but only the audio goes through when I try this (the imported clips are just black). I also was successfully able to import them after converting them to .wmv files in Windows movie maker. However, when I exported them in this format, there was significant variable audio lag that, I have discovered from this forum, is probably attributable to the fact that Windows movie maker is not a good transcoding software, and .wmv is not a good editing format.

So basically, I was wondering if anyone has any suggestions as to what software to use to convert my files so that I can import them, and what format/codec to convert them to so that they can be successfully imported and properly edited in lightworks. Or maybe my original files are supposed to be able to import and there some kind of glitch with the software?

Technical question on Red and Alexa workflow - by: fredgasc I must say that I'm very pleased with the latest beta.

I've been using the Alexa's Luts, like the implementation. Clear, simple and straighforward.

What's not yet clear for me, is that if it is possible to load RMD files from Red and-or .XML files from Arri in order to be able to apply a definated look created or in RCX, or in ARC3 in a selection of clips in the timeline or the bin.

More or less like a set-source-settings in Avid?

Maybe that could be a good feature request.]]>

Help with getting to NTSC Format! - by: croland
Can anyone point me in the right direction with fixing this issue? Is it only certain frame-rates that work with certain formats? Or is there a way to get it to use NTSC?

Thanks! ]]>

Hardware question - by: trusteft new here, just bought Lightworks and I am about to build a system just for it.
I am in a hurry so here it goes. For the Windows version.

CPU, i7 + is the minimum, is there a maximum? Will the program use to the full advantage a 6 or 8 core CPU? If yes, is the speed different from a regular 4 core 8 thread, worth it?

GPU, the program doesn't use CUDA, right? What GPU do you suggest, would a 970 be good enough? Not good enough?

RAM, I am thinking about 32GB DDR3 (most likely), good, bad, enough not enough?

SSDs, worth it for this program? Meaning, am I going to see a real difference in speed (lightworks only related).

Again, this PC is going to be JUST for lightworks pro, no games, no whatever else.

Thank you in advance.]]>

frame rates - by: fantasmatica I'm trying to import some videos into lightworks, but there is one where at the column for "rate" it just says in red script instead of a framerate 48kHz.. the format of the clip is 640x352. I can import other clips with the same format into the project. then there's another video where it's the same but for the format it just says 16bit. I can import it, but it's only the audio. I can also import other videos, taken with the same camera, I don't know what is wrong with that particular video..?

the exported material turns black after a couple after runnign just fine.... - by: nodetree The odd thing is that i manage`t to make some clip collaces that worked but then when adding longer Tiles/clips i have the black screen problem.
I then tryed to use eyeframe, with-out a proxy , just a usual convert, but that seemed to make things even worce because now even long files that i got to work are corrupt and they alsoy after a while runnign good and showing my animation sudden turn´s black . But i don´t want to give up on lightwork just yet because it seems so nice, but what should i actually do to get these clip´s to work, what exactly should i do with eyeframe. And my only option as a free version user is to get the edit out as a mp4 i think .
Can it be that i just run out of RAM with the longer clips because i managed to make a minute long clip , but then i run out of luck and get these problem ?

MP4 Import Audio Problem - by: cody_
This image is hidden for guests. Please log in or register to see it.

From this picture it looks like there is no audio on the end at all, but it is when playing it in Lightworks.
But it is out of sync. And not just by a second or so.

Here is the file that causes the problem:

The file plays fine in VLC player.]]>

RED gurus help required - by: fredgasc New to lightworks, still in the learning curve process.

Here is what I see.

1) cutting R3D at 8th reso

export to film I.S 4K, the 8th reso quality is maintained on export (and of course not usable).

2) changing the reso to 1:1

the export is done with max quality as it should. follow me I'm sure.


Have hard time to find reliable infos on rock solid workflows with R3D files within LW, and specially when conform is concerned.

Is there a dedicated topic on LW-Red where I could find experienced Red users cuttin with LW? That would be great.

Exported With Chipmunk Voice - by: Brotuulaan
Again, I say, wtf?

I edited my video as normal, previewed it as I went along, and all seemed right with the world. Then this happened.

I tried a straight-up export again, but that yielded the exact same results.

Video Importing As Audio - by: Brotuulaan
Format lists it as "16 Bit" instead of "1080p, AVCHD."

Rate lists it as "48Hz" instead of "30 fps."

Here is a MediaInfo analysis:


Here are the results from the last video I recorded and transcoded


From some of the initial statements in the file summaries of these two video files were the same, so I'm at a loss as to why the last file imported as video and this one was strictly audio. I haven't changed any settings in my transcoder between then and now.

Also, the file opens up fine in media players on my computer, with both video and audio playing fine. I've imported it into LW multiple times with the same results, and I've redone the transcoding job with the same results as well.

Any ideas?

***I'm trying to import it via LW's transcoder, so I'll update this thread once it's finished.***]]>

Audio starts too late - by: mezzix i have a GroPro Hero3 and use the settings 720p and 60fps. When i import my clips in a project(using 60 fps) the sound doesnt match with the video. When i use 30 fps as the project framerate the sound does match. But i can't do that right?
What am i doing wrong? In the forum i found a solution but i don't want to change the speed of every audiotrack.]]>
