When I export my videos from Lightroom after editing why their quality degrades?

Hi @rajan272867598huq 

Thanks for reaching out.

Which version of Lightroom are you using? How are you exporting your images?

Please check this conversation and try out the suggested steps: https://community.adobe.com/t5/lightroom-classic-discussions/loss-of-image-quality-when-importing-and-exporting-in-lightroom-for-the-purpose-of-metadata-only/td-p/11242118.

Let us know if it helps.
