Video Messages
Updated: Nov 3, 2025
Video messages display a thumbnail preview of a video image with an optional caption. When the WhatsApp user taps the preview, it loads the video and displays it to the user.
Supported Video Formats
Only H.264 video codec and AAC audio codec supported. Single audio stream or no audio stream only.
Note that videos encoded with the H.264 “High” profile and B-frames are not supported by Android WhatsApp clients. We recommend that you use H.264 “Main” profile without B-frames, or the H.264 “Baseline” profile when encoding (or re-encoding with a tool like ffmpeg), and place moov boxes before mdat boxes, for broader compatibility. If you are using ffmpeg, you can use the -movflags faststart flag to place moov boxes before mdata boxes.
