Importing MP4 generated from OBS takes extremely long/not working - by: Atmaz http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=69146&Itemid=81#69146 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=69146&Itemid=81#69146
Initially, the file takes a long time 'analyzing." When I import it, after about 5 minutes with the program hanging (windows asks me if i want to close it), it finally appears available to the project. Finally, when I go to play the file within the project, it appears to be fine, but once the play button is clicked nothing happens and the program hangs, forcing me to restart it.

Here is the MediaInfo for the mp4 I am trying to import:

Importing photographs forcing SOME images to 720p - by: williamskg6 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=69111&Itemid=81#69111 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=69111&Itemid=81#69111
There does not appear to be any setting to disable this tremendously frustrating behavior in the importer.]]>

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?]]>
