The Nintendo 3DS has no native video player app and does not support standard video formats (MP4, MKV, AVI) out of the box. It's a gaming handheld, not a media player. However, workarounds exist.
Best option for actual playback. Requires Custom Firmware (Luma3DS).
Prep: Convert videos to **H.264 Baseline/Main Profile, 400×240 (top screen), 30 fps, AAC audio, MP4 container** using HandBrake (preset: "Fast 480p30" → resize to 400×240).
