Some video software creates MP4 files that are not compatible with X/Twitter. For example,
Camtasia versions older than 2019.0.9 create MP4 files that X/Twitter rejects. Please check
your video software for compatibility. See
here for more
information.
X might have an issue processing video media hosted on Dropbox or signed URLs (for example an
S3 signed URL). If you encounter an issue, we recommend using an alternative hosting provider
or uploading directly to Ayrshare.
If you’re using a video creation tool and you’re having issues publishing your video, try
re-encoding the video.
