Is anyone else having issues with closed captions not showing properly in full screen mode?

[myerdon01]

I have an instructor that contacted me today with this issue:

> I have a question regarding closed captioning in Canvas. In adding closed captioning to my videos, I've noticed that the captions are OK if the videos are played at normal size. However, of the video is played full screen, the caption lines overlap and are hard to read. Any insight on this issue? I created the video in Camtasia 3. If I export the video to TechSmith's (the Camtasia vendor) site, the closed captions work fine regardless of window size.

Any help is greatly appreciated!

There are multiple multimedia services that can be attached to Canvas (Youtube, Kaltura, Mediasite, ARC, etc), but Canvas itself doesn't have a video playback capability.  How was this video added to Canvas?

This is what I have gathered from this instructor:

I created a folder in my Canvas files to hold all of the lecture videos. I then created a page with a link to the video. After clicking on the video link, I clicked on the "cc" button and selected "Upload subtitles" to load the subtitle file (which was exported from Camtasia).  I am attaching three screenshots; one showing the page with the video links, one showing what it looks like at normal size, and one showing what it looks like full-screen.

This is what the full screen version looks like:

I never heard back from my instructor, so I would have to assume he figured out the issue on his own, or found a work-around!

I was researching a similar problem and found some things that might be helpful if others ever run into this.

My specific issue was that an instructor was uploading the autocaptions from YouTube to Kaltura, but the concepts should generalize fairly well. The autocaptions used overlapping cues, sort of like a rolling transcript, and Kaltura didn't adjust their position so they displayed over each other.

If YouTube autocaptions are the source of your issue, be sure to click the Duplicate and Edit button in YouTube before downloading (and ensure your captions are accurate while you're at it), and that will convert them to a format that doesn't use overlapping cues.

These overlap issues can also be caused through other means as well (e.g. converting a .vtt to an .srt). I found this subtitle overlap fixer command line utility that will help to resolve them, but I'm not sure if there are any more user-friendly options.
