Lightroom Classic CC 8.3: Video export in "Original" format fails

Lightroom Classic 8.3.1 was released today and contains a fix for this issue. Please update to 8.3.1 and verify that you are no longer seeing the issue. Thank you!

Ian,

I'd like to try to reproduce what you are seeing. Can you give me specs on the file format, codec, and original camera producing the video so I can match up?

Same behavior on my LR 8.3 / Mac OS 10.14.5. Trying to export this file as Original:

shows the progress bar completing, but the file never shows up in the selected destination folder.

Since the update to v8.3 Lightroom refuses to publish video. There is no error, it just skips over them. I've tried different publishing services and am using the "Original, unedited file" option. I've reverted to version 8.2.1 since video publishing is critical to my workflow.

Windows 10, I use a plugin and originally reported the issue to the author, he suggested I try the built in export to Hard Drive publish option which I did and it still did not export video. I also found that Exporting without a publish service (to the Hard Drive) does not work either. The video's are all mp4, a mix from my phone as well as a Panasonic camera.

My test works in 8.3.1, thanks.

The problem exists unter Lightroom Classic 8.3.1 as well!
No video export in "Original" mode.

Problem is with video PUBLISH, not export. First video is published, then Publish hangs on second video. Occurs with LR built-in Hard Drive Publish, as well as third party Collection Publisher. Note: Problem only occurs when Graphics Acceleration is on. LR 8.3.1. OS X Mojave. 2017 iMac.

It.s not possible to export photos i LR 3.0 and LR3.1. It.s ok in LR2.8

Interesting. Unable to duplicate the problem now (LR built in or third party publish)! Both publish videos with or without graphics acceleration/ with or without "original format". Only change was probably unrelated computer restart.

I have what appears to be same issue. I can not export a video of a set of photos. It hangs up for ever. HOWEVER, I did find some post of similar issue with 7.1 release in 2017. The issue there was that they had some photos in landscape and some in portrait. When they made the portrait images landscape (photoshop) then video export worked. I have the same issue 3 photos in landscape from my DX7100 RAW (actually DNG), one iPhoto portrait and 1 WhatsApp inport that is portrait. When I turn all into landscape with same aspect ratio (4x5) the video export works fine.

IS THERE A FIX FOR THIS!
