Lightworks: The professional editor for everyone - Forum Kunena Site Syndication Wed, 06 May 2015 02:26:09 +0000 Kunena 1.6 Lightworks: The professional editor for everyone - Forum en-gb Black Screen (but Audio) of a Videoclip - by: Irgendwatt
I have a big problem with the following .avi Video

after importing the video and dragging it into an edit, in the player window of the edit the screen is just black. The Audio plays normal.
In the VLC Media Player and the Windows Media Player the Video plays normally, so it should not be a recording issue.
Already tried something with the import options (changed the video transcoding to file type AVI and the compression to "matrox yuyv hd 8-bit") but the same problem.

thanks for your help!

I just love Lightswork, it's so easy to use and so comfortable to work with :3

But I've been having this problem lately where I am unable to export :/
The message pops up saying that it was unable to create/write the file. If anyone could know what could possibly be causing this problem or know a solution on how to fix it, I'd love your help.

Thank you!

Oh, and I am using the free version btw ;P]]>

Burning Standard DVD - by: Editor23 I have 12 pro and I am confused I need to burn a standard DVD and since that can't be done within LW Pro I downloaded DVD STyler but doesn't the DVD export in LW just makes an ISO file that can be burned as a standard DVD even in Windows disc burn.
If have missed something I am finishing a 50 min video to be used as background video and music for a presentation and wish that there was a simpler way. If there is someone let me know
Thanks in advance for your help

Can .flv files not be uploaded? - by: Arariel
Does Lightworks not allow you to upload .flv files? If no, do .mov files work?

Export clip as single frames? - by: Kermit2004 just wondering if there is an easy way to export a clip as a set of single frames - like you can import an image sequence - export a sequence of images?
So far I used snipping tool but this is very inaccurat and tedious (but as you can see in this case the image quality is not important for me for this task ).
Anybody got a good idea how to do that?

Unable to import MP4 media - by: Morten12 Moderated:
This thread has been moved from a very old thread about an issue which no longer applies. The problem you experience is more likely to be answered here - jwrl.

I have the same issue.
MP4 is "unable to import into current project: check frame-rate and audio sample-rate"

Lightworks analyses the file:

1920x1440, AVCHD

47.95 fps

but it does not support the import.

I don't see the error. Please help.]]>

DaVinci round tripping - by: st599
Have a set of video files shot on a Panasonic Vatican S35 shot at a mix of 25 and 50 fps. I've edited the proxy files and created an EDL.

When I import the EDL, it works for some of the files, but for others it chooses the incorrect in-points. Has anyone managed a mixed frame rate round trip? How do I fix this?]]>

Problem exporting and reimporting from archive - by: angdrake13 Codecs / Importing / Exporting / Transcoding Fri, 24 Apr 2015 12:16:29 +0000 audio out of sync after import - by: madstork
I can't seem to make a go of an edit after many months of trying.

I am shooting 720p/59.94 in .mp4/h.264.

I created a test project at 60fps, and imported a few files, and they play back out of sync with the audio running slow.

I purchased a third-party transcoder to convert my .mp4/h.264 720p/59.94 camera originals. It was advertised to make all-intra files, but it does not work. The manufacturer confirms that feature is buggy and not currently working. They advised me to try MJpeg .movs at the same rate. I converted my files using this method
and they playback well after the conversion, and are a little more than 400% bigger.

I created a test project and imported one of the files; the audio picture seems to playback just fine, but the audio is in slow-motion.

I was having this same trouble when trying to import the .mp4 files directly?

Am I overlooking some pertinent settings within lightworks?

ready to strangle myself. i'm so stuck.]]>

recommendation needed: best export codec for TV/DVD - by: moses56 I have several projects with different frame rates
most at 24 fps (due to the fact, that I had to use material with different frame rates) a few at 25 fps and some shot and edited in 50 fps.
So far so good. I am considering getting a pro-license to be able to export these videos so I can watch them on TV and burn them on a DVD.
Any recommendation what the best export setting would be, what codecs to use? This is for European PAL TV.
Thanks in advance for any help given...]]>
