Hi guys,

I observe error "Material error at:??? Replace with black" only with the video: Video on my Gdrive or Wetransfer link

It`s a MP4 format, and I always edit this king of video.

See the error.log file:

Hello,

Thank you for the information and the sample.

Please open the shared video in a source viewer with Lightworks V14.5. You'll see, it shows black frames over thew whole duration. That's because the video codec in this MP4 file is HEVC (aka h.265). HEVC isn't supported with Lightworks V14.5 and causes the message 'Material error..' on export. Furthermore, it has a non-standard target frame rate of 30.051 fps which can lead to sync issue with clips of longer duration.

Lightworks 2020 beta supports HEVC. Unfortunately, the clip shows with the latest 2020 beta sync issues far beyond of what I would have expected to see based on the non-standard frame rate shown by Mediainfo.

My suggestion: Install Lightworks 2020, to make use of the newly invented auto rotation, and convert all clips of that kind prior to import with Handbrake to straight 30 fps. Here you'll find suitable settings:

It's better to travel well than to arrive...
