How Do You Download A Codec?/Which One Should I Get? - by: cmholt23 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99598&Itemid=81#99598 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99598&Itemid=81#99598
I'm having really bad issues with trying to edit a video in lightworks. I'm using Action! to record my computer screen and I want to edit it in Lightworks. Action! allows me to create an mp4 or an avi format video, and I've tried both of them, but when I pull either one into Lightworks it becomes choppy. I record at 60fps and I import it into Lightworks at that. I'm wondering, what would be the best file to record into? What would be the optimum fps? and also, what codec should I download for the transcoding into Lightworks hat will make my videos less/not choppy? and lastly, how should I download/install said codec?

I know I'm a total newb, but I promise if you point me in the right direction I'll get out of your hair.

AMD FX-6300 3.5GHz 6-Core Processor

Lightworks 12.0.2 trouble importing .wmv files - by: raderd http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99566&Itemid=81#99566 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99566&Itemid=81#99566
Lightworks 12.0.2 on Windows 10 could not import these files. The import function delivered a single frame image and no sound.

Tried a number of video converters with no luck UNTIL ...

tada ... handbrake.fr/

HANDBRAKE to the rescue. This free utility converted the .wmv files to .mp4 which Lightworks did import (make sure transcode is "file") successfully with good quality image and sound.

lower bitrates possible for export? - by: marko.pekic.radar http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99423&Itemid=81#99423 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99423&Itemid=81#99423 But, could there be a possibility to also have bitrates lower that 1 mbit/s, because such lower rates are very handy for different types of proxy videos?

Also, this bitrate seems like an overkill for smaller resolutions. For example, I can export a nice looking video at 720p with the size of 10 MB and if I export the same video at 480p, it is still 10 MB in size because of the lower bitrate limit.]]>

Can I export 2.39 aspect ratio - no black bars - by: jumptolightspeed http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99378&Itemid=81#99378 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99378&Itemid=81#99378
My question is how can I export widescreen without black bars. I'm using the free version. I want to go with the pro version but I wanted to make sure I could do this before I pay for it, since a lot of my work is widescreen and I need to output to 1080.

Thanks!

Lightworks won't export the edit - no file is being created - by: Atulin http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99364&Itemid=81#99364 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99364&Itemid=81#99364
It's a free version, so there's not much export settings I can change. 30 FPS, 480p. Every single time I try to export this file the result remains unchanged.]]>

No one wants to watch gaming video in 25 fps, so does anyone have a solution to this?]]>

Video in Preview Window Shakes Up and Down - by: EvilNazgul616 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99344&Itemid=81#99344 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99344&Itemid=81#99344
I'm new to lightworks, and I'm trying to make a video. However, after importing a clip I noticed that it tends to shake up and down a few pixels in the preview window, despite the effect not being present in the clip when opened in a media player.

I looked it up, and apparently the solution to this problem is to go to display optimization and change it to frames. However, I can't seem to find "display optimization" anywhere! I eventually looked it up and apparently display optimization fields/frames no longer exists in the newer versions.

So what do I do?

I'm using the most recent version.]]>

New workflow. - by: donkpow http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99342&Itemid=81#99342 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99342&Itemid=81#99342
I am capturing with OBS in lossless H264 with variable frame rate (impossible to avoid). The NVENC encoding turned out to be a bust on quality.

Take that lossless VFR AVC.mp4 video and convert it with ffmpeg to containerized mov (png/mov) and force CFR. Create a proxy (prores) for editing in 32 bit lightworks. Find material to fill (png/mov) on the proxy and export to image sequence.

Import that image sequence to Lightworks 64 bit and Fusion if needed.

Keeping in image sequence avoids banding that occurs in all compressed media sourced from the OBS video.

Encode for delivery with ffmpeg to AVC/mp4.

I haven't tested all of the workflow yet. What do you think?]]>

Beginner problems: Glitchy audio when importing Gopro videos - by: brzrkr http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99326&Itemid=81#99326 http://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=99326&Itemid=81#99326
Source video: 1080p 48 fps and 48hz audio sampling (if my google-fu is right) taken by a GoPro Hero 3. It's a 15 minute long video that's 3 GB in size. Every time I play the source video on windows media player there are no issues with audio or video.

I have a AMD Phenom II quad core with 8GB of RAM and a modern gaming video card. I forget the series.

Right now I'm trying to import and edit video I took of driving a Lamborghini on a track. I've opened the new project as 1080p and 48 FPS to match how the video was recorded. Every time I import it, the audio seems to lag or glitch when I play it. It's like it's out of sync with the video. It sounds out of phase and I get regular clicking and chopping out of the audio which eventually bogs down the video.

I've tried fiddling with the settings on setting up the project in the main screen but I haven't come up with something that resolves the issue. Both of the projects I've edited before were from the same GoPro, albeit I think those were taken at 720p. I know export is limited to 720, but I didn't think import would be an issue.

Any ideas what's going on or what I should know about this?]]>
