I am mystified.

I can upload a Facebook video, make proxies, and edit. Bingo. Success.

Then take another video, try to make proxies, and it will sit there for hours trying to complete the background task.

Why?

If proxy creation is the only task you see and not, as in the other discussion, proxy creation is on hold waiting for a running task to terminate, a Mediainfo report might (or might not) show the cause.

(Heavy sigh) I find the instructions for the media report so difficult. But OK, I will try again to learn it. Stand by.

I try it in a simple manner:

  1. Download Mediainfo from here: mediaarea.net/en/MediaInfo and install it.
  2. On first startup, you'll see the 'Prefernces' window of Mediainfo. Make sure that 'Explorer extension' is checked and click 'Ok'.
  3. Right-click on the media file to inspect and select 'Mediainfo' from the context menu to open the file.
  4. In Mediainfo, select 'View > Text'.
  5. Press Ctrl+A then Ctrl+C to mark the text and copy it to the clipboard.
  6. In the text box of your forum post press Ctrl+V to insert the text from the clipboard.

Hope that helps.

Figmo124

how does that look? can you cancel the background task? or is it staying in the background, even when you cancel it?

Thanks a lot.

I think the audio format of this file is the problem. It says "Format : AAC LC SBR" where SBR stands Spectral Band Replication. Lightworks doesn't like that.

I'd suggest converting this file prior to import with Handbrake. I usually recommend these settings (set the frame rate to 30 fps, according to the target frame rate of the video):

www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=166802&Itemid=81#209009

After converting, you should be able to import and export without trouble and edit fluently without proxies.

If I understand it correctly, the proxy creation hangs in the beta version and no error message is displayed.

I don't know if Lightworks can change this, but maybe a note in the beta forum would be useful?

I think so too, it sounds like exactly the same behavior that I have with proxy files in the last beta. i wrote into the linux beta forum, would be useful if you would post in the beta forum of your operating system as well...

kalimerox,

I can't imagine hat your problem is the same as figmo124's problem, unless you are using AAC at very low bitrates with SBR.
