Most of the movies on NetNaija are encoded using the HEVC aka H.265 codec to achieve high quality at a comparatively smaller size and might not play on some old video players / devices.
For the aforementioned reason (size), we try not to use the more widely supported predecessor H.264 or MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC).
Support for HEVC is not very broad as at writing this, so we recommend our visitors use the latest version of VLC Media Player - our most trusted cross-platform media player.
For those who intend to play these videos on their televisions, we recommend you read Why Don't NetNaija Movies Play On TV?
