Attempting to add subtitles to an MP4 file on Google Drive by selecting it and clicking More Actions/Kebab Menu > "Manage caption tracks" > "ADD NEW CAPTION TRACKS" > "Upload" > "Select a file from your device" > "UPLOAD" resulted in only "No tracks added" over and over.
Jason H. 956 kindly shared the solution:
[I]f you happen to be on multiple users try opening an incognito window and sign in to only one account. Then try to upload the captions to that file.
Google really needs to add this fix to the "Caption error messages" section of their Add caption tracks to your video files, which currently only offers:
If you get and [sic] error while uploading your file, make sure the file is:
- In the correct format. only [sic] SubRip (*.SRT) and SubViewer (*.SUB) are supported.
- Not too large. The caption file must be less than 2 MB.
- Not longer than the video. If the file is longer than the video, the video won’t be able to auto-sync.
