Introduction

By adding subtitles to your videos, you can enhance the video-watching experience of your subscribers/viewers. They can watch a particular video with subtitles in their preferred language. A particular video can have one or more subtitles in different languages. Viewers can choose their preferred subtitles in the Muvi player during the play of the video. You can upload subtitles in .srt, vtt, .stl, .smi, and DFXP formats only. You can add subtitles to trailers as well. We also support Closed Captioning (CC) in subtitles.

Note:

.smi format subtitle is only supported in Samsung TV Apps.
The subtitle is not supported in iOS devices (Browsers) when played in full-screen mode.

How to Upload/Add A Subtitle

Navigate to “Content Management” -->“Asset Library” in the CMS
In the Asset Library, click on the “Videos” tab.
On the right-hand side of a video click on “Subtitle Icon".
Click on the "Upload Subtitle" button.
Select the language from the drop-down menu.
Click on “Upload” to upload the.SRT, VTT, or DFXP subtitle file in the language that you have selected from the drop-down. Upload the file from your device.
The subtitle will be added to the video.
Repeat the process to add another subtitle in different languages.

Note: We do not support style characters in DFXP. We remove all the style characters and convert the subtitle file to VTT.

Adding Subtitle to Trailer

You can also add subtitle to trailers by following the above-mentioned procedure. When users play the trailers, they will see the subtitles. However, you cannot add subtitles to any third-party videos (e.g., YouTube, Vimeo) added as trailer.

How to Delete a Subtitle

To delete a subtitle that is already added to a video, perform the following steps.

Navigate to “Content Management" --> “Asset Library” in the CMS.
In the Asset Library, click on “Videos” tab.
On the right-hand side of the video click on the “Subtitle Icon”. You can see the subtitle(s).
Click on the “Trash Icon” on the right-hand side of the “Subtitle”.
When asked for confirmation, click on “Proceed”.
The subtitle for the video will be deleted.

Note: If you delete the specific subtitle, it will not be displayed on the player when users try to play the video.

Click on the "Subtitle" tab.
Under "Subtitle Behavior", select the checkbox "Subtitle On as Default" (see below screenshot).
Click on "Save".

To change the appearance of the subtitle, navigate to "Player" -->”Player Settings” in the CMS.
Click on the "Subtitle Tab",
Under "Subtitle Appearance" select the "Font Type" from the drop-down.
Select the "Font Size" from the drop-down.
Select the "Font Color".
Select the color for "Background Color".
Mention an "Opacity" level for the subtitle. (e.g., 10%, 20%, 15%)
Click on "Save" to apply the changes. When the users play the video, they will see the change in the subtitle appearance.
