PotPlayer

PotPlayer is a free multimedia player for Windows that handles virtually every video and audio format without requiring external codec packs. It uses hardware accelerated decoding through DXVA, CUDA, and QuickSync to play high resolution content smoothly, even on modest hardware.

What it does

Drop a file onto PotPlayer and it plays. MKV, MP4, AVI, FLV, HEVC, VP9, Blu-ray folders, audio files, even partially downloaded or damaged videos that crash other players. The built in codec library covers everything, so you never need to hunt for a codec pack. Hardware decoding offloads the work to your GPU, which keeps CPU usage low when playing 4K or HDR content.

The subtitle support is thorough. PotPlayer loads SRT, ASS, SSA, and SUB files automatically if they share the filename with the video, and you can adjust font, size, color, position, and timing sync from the subtitle menu. For streaming, you paste an RTSP, HTTP, or MMS URL and PotPlayer connects directly, making it usable as an IPTV player for internet television playlists.

Playback speed adjusts from 0.1x to 16x with the C and X keys, which is practical for lectures and tutorials. The bookmark system lets you mark specific moments in a video and jump back to them later. Frame capture saves the current frame as PNG or JPG, and a batch capture mode can extract frames at set intervals across the entire video.

Who it is for

I use PotPlayer as my daily video player because it handles every format I throw at it and starts faster than the alternatives. If you watch a lot of video content, especially high resolution files or streams with subtitles, PotPlayer gives you more control than VLC with a smaller footprint. For users who prefer open source software or need cross platform support, VLC or mpv are better choices.
