it is generally true that WhatsApp has limited support for video formats and does not natively support the H.265 (HEVC) codec.
Here's a more detailed explanation:
Supported Video Formats: WhatsApp primarily supports video files encoded with the H.264 (AVC) or MPEG-4 video codecs, within containers like MP4, AVI, MOV, and 3GP. They also mention support for MKV and FLV in some.
H.265 Incompatibility: The H.265 (High Efficiency Video Coding), also known as HEVC, is a more advanced codec that offers better compression efficiency and quality at lower bitrates compared to H.264. However, WhatsApp does not list H.265 as a supported codec. Videos encoded with H.265 are likely to either not play within WhatsApp or fail to be sent.
