Frequently Asked Questions
Q. How should I decide between Video and Rich Video Message?
A. Choose "Video" if you want to trigger actions upon view completion, or "Rich Video Message" if you want to make an impact with auto-play.
The Video feature allows you to start a LITTLE HELP CONNECT chat flow triggered by view completion. On the other hand, Rich Video Message auto-plays when displayed in the LINE chat screen, making it easier to catch users' attention.
We recommend choosing based on the purpose of your distribution.
Q. Can I change the display size of the video?
A. You cannot change the display size within LITTLE HELP CONNECT.
On LINE, the display is automatically adjusted according to the video's aspect ratio, but the display size itself (display area) is fixed. If you want to change the display format, you need to create the video with your desired aspect ratio in advance (e.g., 16:9, 1:1, 9:16, etc.).
However, some cropping may occur on LINE chat due to display area constraints, so it's recommended to place important elements in the center.
Q. Can I specify a thumbnail image for the video?
A. Currently, it is not possible to specify a custom thumbnail.
The current specification automatically displays the first frame of the video as the thumbnail. Therefore, many users insert a static image of their choice for about 1 second at the beginning of the video to use as a thumbnail substitute.
Q. The video preview is not displaying properly
A. The preview may not display correctly in the message distribution settings screen, but as long as there are no errors, there is no problem.
If you want to check the actual display on the LINE app, please use the "Test Send" function in message distribution.
Q. Can I upload video files larger than 30MB?
A. Direct upload to LITTLE HELP CONNECT is limited to 30MB.
If you want to use files larger than 30MB, please consider uploading to external storage services (YouTube, Vimeo, etc.) and sharing the URL in your message. Rich Video Message provides an option to "Use external storage."
