ALLPlayer vs KMPlayer

ALLPlayer is a movie and music player for Windows, Android and iOS, with built-in codecs for playing multimedia formats. It can find and download matching subtitles through OpenSubtitles.org, and its speech synthesizer reads subtitles aloud with adjustable voice and reading speed. AI Voice-Over creates narration from SRT subtitles and can use a sample of the user's voice. That feature requires an internet connection, an active package and a video file, and generated voiceovers are limited to files the user has full rights to. The desktop player includes local and global radio stations organized by music themes. ALLPlayer Remote lets a phone control ALLPlayer, VLC, Windows Media Player, Netflix, YouTube and PowerPoint, and transfer files between a phone and PC. Parental Control password-protects videos, but losing the password means losing access. The player has a free plan; AI voiceovers are sold in one-time packs, starting at 1.40 USD for one voiceover.

KMPlayer is a media player for Windows, macOS, iOS, and Android, with network playback, subtitles, hardware acceleration, and 4K playback. Listed formats include AVI, MP4, MKV, MOV, WMV, FLV, MPEG, MP3, AAC, FLAC, WAV, SRT, ASS, SSA, and WebVTT. The mobile app can transfer files between a phone and PC on the same Wi-Fi network and includes cloud playback. Users can change subtitle size, color, and position, and adjust playback speed from 0.25x to 4x. Video can play in the background, and YouTube playback is available by entering a URL. Premium features for Android include magnet playback, GIF creation, media cropping, and MP3 conversion. KMPlayer 64X supports 4K, 8K, UHD, and 60FPS video, and the PC versions are available in 32-bit and 64-bit editions as well as Mac.
