Why does my Canva video download fail after I embed a YouTube video?

Yep—Canva says a YouTube embed can make a video download fail, so the timing is a pretty strong clue. An embed isn’t an MP4 Canva can render into the export. Remove or replace that embed and retry. If you have the rights to the video, get the original MP4 and upload it to Canva instead. If the goal is to let people watch the YouTube clip, share Canva’s watch link rather than trying to bake the embed into an MP4. If it still fails without the embed, make sure uploads have finished processing, look for a broken element, and simplify or split a very large design before retrying.
