It's a very common issue that an error message "unsupported video codec" will pop up when you edit or play some video files on specific devices, programs or upload to UGC websites. In this case, you may want to know "how do I find the codec of a video?". Next, I'll introduce 3 effortless methods to check video codec in several seconds. Let's get started.

Video Codec is NOT a Video Format or Container

Video codecs refers to the video compression standards implemented through some software, devices or hardware applications. Each codec comprises of an encoder and decoder to compress and decompress the video in lossy or lossless mode. Here are some popular video codecs: H.264, HEVC, XVID, DIVX, MPEG1/2/4, VP8/9, etc. While a video container format encapsulates video and audio tracks/streams compressed by different codecs, such as MP4, MKV, MOV, WMV, AVI, WebM, etc.

For non-tech-savvy guys, just ignore above crap. In a nutshell, just imagine a glass of lemonade, the glass represents the container format, while the lemon juice and water stand for video/audio codecs. So if you don't like lemon flavor, although the glass is quite beautiful, it's absolutely not your taste. That's the crucial reason why your video won't play on some devices even though it's indeed a supported format. To avoid the "unsupported video codec" issue, the question is, how can I tell what codec a video uses? The following content will give you a satisfactory answer.
