If you see a "transcription error" after uploading a video via a YouTube link, it may be because some YouTube videos do not support this upload method.
If this happens, you may need to upload your video another way.
You can download a YouTube video you own as follows, then upload the file to Subanana:
Go to YouTube, click your avatar, then go to "YouTube Studio" > "Content" > "Videos" > the options menu of the video you need > "Download" to download the video.
In the Subanana tool, click "Upload media" > choose "Upload media file" to upload the video.
For other ways to download, see the following article: External link
