MP4 is a widely supported container for video and audio. Compatibility and file size depend on the codecs and settings used inside it, which is why MP4 with H.264 video and AAC audio is a common choice for sharing and uploading.
MP4 is widely supported by browsers, phones, smart TVs and desktop players. Playback still depends on the video and audio codecs stored inside the file.
FLAC is a lossless audio format that compresses music with zero quality loss - every detail of the original recording is preserved. It is the favourite of audiophiles and for archiving CDs, though files are much larger than MP3.
FLAC plays in VLC, foobar2000, and most modern players; for iPhones or car stereos that reject it, convert to MP3 or M4A.
