Images and videos

Koinè allows you to enrich the staging of your production by integrating images and videos directly to your surtitles. These can appear in their own cards or be used as backgrounds.

Supported file formats

Supported image formats

The following image file formats are supported:

  • JPEG image (*.jpg, *.jpeg)

  • PNG image (*.png)

The maximum image size is 8192 x 8192 pixels.

Supported video formats

The following video file formats are supported:

  • AVI file (*.avi)

  • MKV file (*.mkv)

  • MP4 file (*.mp4, *.mpg4)

  • MPEG file (*.mpg, *.mpeg)

  • MOV file (*.mov)

Video stream decoding relies on the hardware acceleration of your computer. Supported codecs may, therefore, vary from one computer to another. To maximize content compatibility, we recommend using the MPEG-4 Part 10 (H.264/AVC) High Profile Level 5.1 video codec when encoding your own videos.

Image and video display

Images and videos are displayed in the background of the cards. This makes it possible to overlay surtitles on top of them.

The content of images and videos is scaled to fill the entire surface of the card. When the aspect ratio does not match that of the card, the sides of the image or video are cropped.

Video playback starts when the surtitles are projected. In edit mode, only the first frame of the video appears in the display preview.

Insert an image or video

To insert an image or video, place the text cursor in a card, then choose Cards > Insert Image or Insert Video. Select the file to insert in the dialog box, then click OK.

A thumbnail image of the selected file will appear at the top of the card to indicate that the video or image has been inserted.

You can also insert an image or video into multiple cards at once. Select the cards where you want to insert the image or video, then choose Cards > Insert Image or Insert Video. Select the file to insert in the dialog, and click OK.

Delete an image or video

To delete an image or video, select the image or video by clicking on its thumbnail, then choose Edit > Delete or press Delete.

Tip

You can quickly select multiple images or videos by selecting the cards that contain them and choosing Edit > Select > Select Media.

File links

When an image or video file is inserted, a link to that file is created. If the image or video file is located in the same directory as the surtitle file of your project, a relative path is established. This makes it possible to move the surtitle file and the image and video files to another location without breaking the links.

To reveal the path of an image or video file, hover the mouse cursor over its thumbnail for one second.
