When exporting vertical videos (1080x1920) from Premiere Elements, they appear as landscape on YouTube when uploaded from a laptop. This issue does not occur when uploading from a phone, suggesting a problem with metadata or export settings specific to desktop uploads.
Yesterday I exported a vertical video from Adobe Premiere Elements at 1080x1920. The MP4 file itself plays correctly as vertical on my laptop. But when I upload it directly from my laptop to YouTube, it shows up as landscape (so not as a proper Short). The strange part: if I first copy the exact same MP4 file to my phone and upload it from the YouTube app, it gets recognized as a vertical Short immediately. Another detail: if I upload the same file from my laptop to TikTok, it also posts correctly as a vertical video. So it seems to be something specific about uploading to YouTube from desktop vs phone. Has anyone experienced this? Is this related to metadata/orientation or export settings in Premiere Elements?
