I then put the mp4 into Lightworks and trimmed it and added some text at the end.

I made sure to close the gap.

I export the video as an mp4 and look at it in Windows 10 Movies and TV.

Lightworks took 2 hours to export my 30 minute edited livestream as the unedited livestream. The exported mp4 is the same as the one I downloaded from Youtube Studio.

I tried this a couple of times and every time the edits were ignored.

What am I doing wrong?

I attached some stuff from MediaInfo.]]>

Different Framerate Videos not uploading - by: Liung
- The problem described doesn't seem to quite match mine, and the solution does nothing
- The thread seems to have been from years ago and I literally cannot find the options the solution describes in my current version of Lightworks
- The language used in the solution is so technical that I literally can't understand what it's saying

I am woefully ignorant about what codecs, framerates, resolution, transcoding, and all this stuff even MEANS. I've been trying to read up but it's just so dense and impenetrable for someone who has no background in this.

I had one project I was working on, and then decided to start another project that would use a lot of the same clips as the other one. I thought, hey, rather than make a new project and have to hunt down and make subclips of the exact same videos, I'll just make another sequence in the same project and still have access to all the same imported files! (I found out later during my search for answers that there's apparently a way to send bin contents to a different project, however that isn't working either, more on that later.)

If I click on the project name and go to the "video" tab it says the output format is 1080p (sf) 24fps.

Then I started importing more videos and everything went to hell. Most of the videos I have are taken by other people, on various cameras. So I had NO IDEA that all these other factors mattered--an MP4 is an MP4, right? Why would I have to worry about one MP4 file working and another one not, RIGHT??

This video works fine in this project, and so do others from the same camera.

It was hard to tell at the time because most of these videos are underwater, but this video and ones like it import such that the audio sounds normal, but the video plays in slow motion. I wasn't too fussed about this for the original project, slomo underwater looks nice.

Then I started trying to import this video, which is 3+ min long, and more than half of it is above water, so I actually noticed that the audio wasn't matching the video even a little. Also, it would only import 1 minute of the video. Since the video was playing in slow motion, that meant only a tiny fraction of it was actually being imported, and since I needed the bit at the end and that wasn't even making it into LW... my search for answers started.

I tried lots of things, nothing worked for the reasons listed above, finally the only solution that worked... was someone saying that it needed to be imported into a project with a matching framerate. Okay, fine, whatever, new project. Videoclip says it's 59fps, start a new project with 60fps. Video imports and plays just fine. I find the thread that explains how to use the Bins menu to move a collection of imported files to a different project, great--"Problems copying Bin to new project".

ALRIGHT FINE can't make my life easy that's okay I can just re import the files, I know where they all are this will take unnecessary amounts of extra time but I can--navigating to the folder where the files I want are, the thumbnails are all greyed out and the rate "47.95" is written in red. WHY?!

Okay, start searching how to import videos with different framerates in. Most people saying that a project with 24fps will fix that, but obviously I know it won't because I'll be able to import these videos but some of them will not have the video and audio properly synced up. (Actually I'm not using the audio on most of these videos, so that's less an issue, except for the part where the slower video means it's cut off when the audio ends but the video doesn't.) Finally I find a thread that says, "When you create a new project, select mixed, that's what it's for, making projects with mixed framerate videos!"

GREAT! I go do that!! I import the GOPR3868 file! And... same problem as the original. I look at the project details and it says the project is 24fps.

Trying to look for the answer on my own has been more frustrating than the problem itself. When I started reading about how to fix the problems with differing frame rates, someone said to check the box for "Apply VFR Correction" in project details under the video tab--that option doesn't even EXIST in my program. And I found that same instruction when I was reading the v14.5.0 user guide, where it provided a picture of the menu that doesn't match mine!

I've hit a problem, tried to find an answer on my own, and every solution I found that was either up to date, decipherable by someone who isn't hugely well-versed in all the technical details of what is happening, AND actually had a noticeable effect... brought me to a full circle back to the same problem I started with.

Pls send help. This media file noob is thoroughly stumped. I made sure to get the MediaInfo results on the files I'm using, hopefully it is enlightening. I'm just going to sit here muttering "but they're all MP4s?! What does all this MEAN?!?! I don't wanna go back to Windows Movie Maker!!"]]>

MP4 import, "Importing: Format unsupported" - by: t4x3n
I am pretty new at this

So I have recently switched to a new computer and downloaded Lightworks again. I usually transfer videos from my smartphone to my computer and import them to Lightworks and it has worked great before and I have manage to export 2 videos without any problems, but after the computer switch I'm getting the message "Format unsupported" during import of a video. What is the issue here?

PC shuts down during export - by: Kneecapz
I am trying to export the edit in 1080p Youtube but the PC just juts crashes about 0.5-1 sec after pressing start. It literally shuts down and restarts. When I export 720p, it's usually managing fine but there was a situation once or twice when it died towards the end of a 3 minute movie.

The edit is just a dozen drone and phone clips with more or less no effects aside from dissolve and titles. Because lwks was refusing to import raw videos, I ffmpeg'ed clips from 25 to 30 fps using:

ffmpeg -i <input> -format:v fps=fps=30 <output>

I did start the project as 60fps even though my clips are all 30, but I don't suppose that should be causing crashes. No software should be crashing Windows like that anyway.

My PC is of decent specs, so that shouldn't be a problem either. Attached specs, error log and media info for 3 types of clips in one text file (raw drone @ 25 fps, ffmpeg drone to 30fps and the iphone footage @ 30fps.

I know the phone footage is variable speed but crashes were occurring before I even started using phone clips.

As a possibly related issue, I'll mention that moving the playhead is very laggy and I can't preview effects (only have simple dissolve/title) without placing the playhead right at the start of the effect or a few frames before. If I go even as little as 5 seconds before, once the effect is imminent the original clip continues playing (or goes to black) and there's sort of a freeze while music is playing and timeline continues. And only few seconds later the incoming clip video shows up form wherever position in time it should have been. What I mean is that nothing gets out of the sequence but the effect portion is just screwed.

I've only ever made 2 videos, on two difference computers, and it was the same thing last time, couple of years ago. At that time I didn't have export problems as I was using free version on 720p YouTube format, but slow/laggy experience was the same.

What gives?]]>

Importing mobile phone videos - by: Dave924
In the CS team we’ve been asked to add more mobile videos in response to Covid virus. That is, videos that show our apps running on a mobile phone or tablet with voice over narration.

The challenge is that when I convert the mobile phones into our video editing program, the video editing program puts black borders on each side of the mobile screen view.

The final video looks OK when played on a desktop, but now appears tiny when playing the final video on a smart phone. Do you have any suggestions as to how to get around this, or for tools that work best to capture video solution demos done on smart phones?

The videos are captured from content providers from around the world. Some use programs such as AirServer. Others capture the raw files using iPhone. The resolutions that come in different ranges, the most recent was 342 by 714. I use OBS to capture the videos and then output in Lightworks at 1080p.]]>

Variable frame rate screen capture audio out of sync - Handbrake help? - by: hertoutr
I've had a look at other topics and I think my problem is to do with the fact that I have variable frame rate screen capture footage (with audio track in the same file). I've cut bits of the footage out tn the editor and everything is in sync, but when I export some of the clips are out of sync with the audio.

Looking at the other answers, I guess I will have to start editing again after putting the original file through Handbrake? I've downloaded Handbrake but now have no idea which settings to select or what to do!!

Here's the Mediainfo file for my original video.

Thank you!]]>

Exporting freeze frame AUDIO LOOPS - by: emilie_reigne
I have lightworks 14.5
I'm trying to export my video, but the audio will loop when we get to the freezed frames parts. I made a freeze frame by cutting the said-frame, changing it's speed to 0%.

When checking in the forums, it tells me to update my lightworks which was apparently a bug in the lightworks 14.0 (I seem to have the latest version, so I dont think thats the problem...)

It also tells me to check the "join" button, which I dont have at my bottom right corner and I cant seem to figure out how to make it appear (same with the effect button and I think the other button is... render? Something along those lines. I dont have those buttons, and I dont know how to get them)

I also read in one of the forums that someone changed their freeze frame from 0% to 1% and THAT fixed their issue, but it's not working for me, the same audio problem happens when I export...

I also tried taking a screenshot of the frame I wanted, saved it in photoshop as a jpeg, used THAT instead of my initial freeze frame, but again the same problem happened. Audio loops.

I have a freeze frame with audio from another video, but the other videos audio doesnt work, and the sequence with the freeze frame loops whatever audio I had before the said freeze frame.
I hope this makes sense... how do I fix this?]]>
