That fade-out at the end is perfect, thank you!

Here we go: we.tl/t-sChgi24M8J Hope it looks as expected.

I'll be back tomorrow with a proposal how to optimize your media management.

Re: Exporting on Lightworks 2 months, 1 week ago #205525

It looks great, Hugly!
Thank you for all your help.
I will read what you have to write concerning media management optimization. I am eager to know more about this and avoid this problem from reoccurring.

My pleasure!


There are three main questions about media to be answered prior to starting more complex projects, in particular when mixing media form different sources:

1. Are all formats well supported?
2. Is any of my files damaged?
3. Does the media format perform well?

Referring to your media, can you answer any of those questions?

You surely have noticed that my question above is rhetorical and the expected answer is no.

For you future work, in order to create fluently editable sequences without trouble when exporting or crashes every now and then, and without investing hours, maybe days, to find one faulty file out of forty, it's best best practice to convert everything with well know software to well known formats, prior to import and editing.

On OSX and Linux, a bash script to conform all media using ffmpeg to well supported and stable formats, prior to editing, could look like this - adapted to your export resolution and project frame rate:

#!/bin/bash
shopt -s nullglob nocaseglob
folder=_${0##*/}     # Destination folder: _<script name>
mkdir -p $folder
# Audio 2 WAV
for name in *.mp3 *.m4a *.wav *.wma *.flac; do
   FFREPORT="level=32:file=$folder/${name%.*}.log" \
   ffmpeg -hide_banner -i "$name" -vn -c:a pcm_s16le -ar 48000 -y "$folder/${name%.*}".wav
done
#Images 2 PNG
for name in *.jpg *.jpeg *.png; do
   FFREPORT="level=32:file=$folder/${name%.*}.log" \
   ffmpeg -hide_banner -i "$name" -pix_fmt rgba -an -y "$folder/${name%.*}".png
 done
# Video 2 MPEG-2 I-Frame HD 4:2:0 720p24
for name in *.mp4 *.mov *.avi *.flv *.wmv; do
   FFREPORT="level=32:file=$folder/${name%.*}.log" \
   ffmpeg -hide_banner -i "$name"  -r 24 -vf scale=-1:720 -c:v mpeg2video -pix_fmt yuv420p -intra -q:v 1 -qmin 2 -c:a mp2 -ar 48000 -ab 384k -y -f mp4 "$folder/${name%.*}.mp4"
done


Of course there are some other format choices, if the above doesn't meet your needs.

Hope that helps.

Exported successfully to 720p24 ..

With my relatively low performance computer the export of the test archive also worked fine (without changing the media, Operating system Win10).
Also the RAM load and V-RAM load remained in the normal range during the export.

Interesting are the computer details of mrarchiboldgrimm (especially CPU, RAM, GPU, Video-RAM, free system disk space).

Lucky you that you can export it without converting any media on your machine. V14.6 crashes instantly if you move the playhead to some composites, at least here. Try the segment starting at TC 00:03:52:02.

Problems related to the clip 'dog daycare' are fixed in the next 14.6 beta, fwiw

Hello Great White,

Why am I not surprised that you had already a look into it?

It appears to me that also 'bottling camera.mp4' and cell tower 'camera.mp4' are critical (possibly 'archi watermark.png' as well).

thumbs up!

Re: Exporting on Lightworks 2 months, 1 week ago #205578

Hello, Hugly,
I will try to convert the files prior to importing them into Lightworks.
I'm not familiar with using the so-called 'bash script', but I'll try it next time and I'm sure I'll figure it out.

Is Linux Mint a bad choice for running LightWorks?
I used to use Windows7, but that will be out of date very soon, so I found Mint which can be customized to look very similar (Windows 10 is an eyesore).

Thank you for your help!
Now, how can I delete these threads since it has already been solved?

Hello,

Only moderators and admins can delete entire threads. Usually discussions aren't removed, because they may help others solving similar problems.

Linux Mint is a supported platform and a good choice for running Lightworks. However, some processing power is needed, on all platforms, for fluent editing and good performance. As schrauber suggested, it could be that the export problems on your system are caused by lack of system resources. Nevertheless, conforming your media to well performing standard formats will reduce potential risk of trouble caused by media significantly with future projects.

Re: Exporting on Lightworks 2 months ago #205876

That's true. I've often found old archived posts that did help me on here.

What are some of the well performing standard formats for media? I just make all of my images .png
However, when I want an image to be layered over a video, I make it a video clip .mp4 and put a green screen effect on it.

I am not too sure how to make an image layered over a video so that the video below it shows.

I have a more powerful thinkpad t420 (with Mint) that i'll be using from now on for editing. I think it's a better workhorse for that.

Thank you all again for your help and advice!

Hello,

A Thinkpad t420 is still at the lower end of the list of machines well suitable for video editing. Since it has onboard graphics, which shares RAM with the CPU, it should have at least 8GB of RAM when working with effects, in particular with effects which connect to more than one source (e.g. Chroma Key, Blend).

Prior to answering your other questions, allow two questions from my side:

1. Does the sequence, which made trouble, export with the T420 flawlessly?
2. Have you tried to convert some files with the bash script I've provided earlier?
