Vevo, the video platform part-owned by Abu Dhabi Media, is in talks with Warner Music Group to allow Warner music videos to appear on the Vevo website and app, reported Billboard.
The deal would see the final major music label allowing use of its content by the video platform, which is also part-owned by Universal Music Group, Sony Music Entertainment and Google.
It would exclude rights to YouTube, on which Vevo maintains accounts for artists signed to UMG and Sony, with Warner artists retaining their own YouTube channels, said the report.
News of negotiations between Vevo and Warner first emerged in August.
Vevo reported 18 billion monthly views in July 2016. That number is expected to increase significantly with the addition of Warner's catalogue.
