I'm very new to Lightworks. I've been wanting to use something better than Windows Live Movie Maker for my gaming videos for a while now, and Lightworks seems like a good choice. Although, there's one thing which makes it unusable for me.

Choppy video.

To sum it up, I have an intro clip which was rendered in LWKS because the wmv-to-avi converter I used for it made the audio quality suck. That wasn't too bad - very choppy on 30fps, but when I render it on 60fps, it's not as bad, but still slightly stuttery.
Then, I use Bandicam for recording my videos, at 1366x768 resolution, which is the max my laptop can do. I have it set to the following settings:

VIDEO
Size: Full size
FPS: 30
Codec: Xvid
Quality: 80

AUDIO
Channels: stereo
Frequency: 48000 Hz
Codec: PCM

When I import the AVI created by Bandicam into LWKS, the playback is stuttery. It also happens to be when I export it, it's as stuttery as the playback. I've tried exporting on 30fps and 60fps, both having the stutter. I guess it also doesn't help that I'm trying to link up a 60fps clip with a 30fps clip.

I have:

PC: Windows 7 Home Premium 64-bit, Intel(r) Core(TM) i53210M CPU @ 2.50GHz (4 CPUs), ~2.5GHz, 6GB RAM
LWKS version: 11.5.1 win32

Any help would be appreciated.]]>

exporting doesn't work - by: Hefa75 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=68845&Itemid=81#68845 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=68845&Itemid=81#68845
When trying to export my edit I get errors. I have tried AVI, MOV and AVCHD.

AVCHD claims that the render engine failed to initialize. AVI (DVCPRO 100) and MOV gets the error "The system can not find the file specified".

I don't get it. I just made the edit and all the clips used are where they are supposed to be.

Also I have an issue with no sound in clips with mpg-audio (see different thread) - worked fine in previous version.

Do you Think my best bet is reinstalling?

I am very dissapointed in this latest version. Everything that worked just fine before seem to fail now. Anoyne else experiencing this, or is it only me?]]>

However, when I try to import it into lightworks, although it remains 8 seconds long, it only makes it half way through the animation - it doesn't play the full version that all the other programs seem happy to do.

The sequence was rendered into an AVI file, and comes up as a motion jpeg - I have no idea what this is about, TBH, or what effect its having (if any) and how to sort it (if, indeed, I can).
The rendered frame rate was 30fps, which is compatible with the other non-animated video clips in the project.

I've noticed lightworks has sometimes clipped the first few frames of some of my non-animated video clips as well, at times.

Does anyone know what's going on here, what can be done about it, and why lightworks is having a strop about something that windows movie maker is perfectly happy with?

Workflow question: 120fps video slowed to 30fps - by: inhumangeek http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=68631&Itemid=81#68631 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=68631&Itemid=81#68631
The background is that I have a GroPro Hero 3 Black and some videos will be 60 or 120fps and I want to insert them into my 30fps video, slowed down by a factor of 2 or 4 (i.e. without interpolation) whilst maintaining the video quality/resolution.

Can I transcode & slow down within Lightworks or will I have to use a third-party applications? I am using Linux; I have played around with avconv (ffmpeg) and this works but I am wondering if there is a neater method.

Note that I do not need broadcast quality results I just want to maintain the original quality of the GoPro!

Many thanks indeed.]]>

Mirillis Action - by: G2000 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=68615&Itemid=81#68615 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=68615&Itemid=81#68615 I'm a new YouTuber that is hoping to use lightworks as a good editing tool to give my videos some professional touches. I record with Mirillis Action at 30fps in 720p and output avi format videos. However when I put these into lightworks the side is cut off and sometimes the sound just doesn't get played. I know it works in windows media player and the Action viewer. I don't understand what I've done wrong. Please help.
