Learn MoreFrequently Asked Questions
What's the difference between a video container and a codec?
A video container (like MP4, MKV, AVI) is a wrapper format that holds various components including video streams, audio streams, subtitles, and metadata. It's like a package that bundles everything together. A codec (like H.264, HEVC, VP9) is the actual technology that compresses and decompresses the video or audio data within that container. When a file won't play, it's often because you have the right container but are missing the required codec. For example, an MP4 file (container) might contain video encoded with H.265/HEVC (codec), which older players don't support.
Why do video files become corrupted?
Video files can become corrupted for several reasons: interrupted downloads or transfers, abrupt power loss while recording or saving, storage media failures, software crashes during processing, malware infections, or errors during format conversion. Video files are particularly vulnerable because they're complex and often large. Their structure includes headers, index information, and multiple data streams that must remain synchronized. Damage to any of these elements, especially headers or index data, can render the whole file unplayable, even if most of the actual video data remains intact.
What's the best video format for compatibility across all devices?
MP4 with H.264 video and AAC audio is currently the most universally compatible format across devices and platforms. This combination is supported by virtually all modern web browsers, mobile devices, smart TVs, and media players. While newer formats like HEVC/H.265 offer better compression and quality, they aren't as widely supported, especially on older devices. For audio-only files, MP3 remains the most compatible format, though it doesn't offer the best quality. When sharing videos that need to work everywhere, MP4 (H.264/AAC) provides the best balance of quality and compatibility.
How can I play videos that have missing codecs?
There are several approaches to playing videos with codec issues: First, install a versatile media player like VLC or MPV that includes built-in support for most codecs. Second, you can install codec packs like K-Lite Codec Pack (Windows) or Perian (Mac) that add support for various formats to your system and existing players. Third, specifically identify the missing codec (often shown in error messages) and install only that codec. Finally, if none of these work, convert the video to a more compatible format using software like HandBrake or FFmpeg. VLC is usually the quickest solution as it requires no additional codec installations.
Will converting files to different formats reduce quality?
Yes, converting between formats typically results in some quality loss, especially when converting between lossy formats (like MP3 to AAC, or MP4 to WebM). This is because each compression step discards some information that can't be recovered. The effect is cumulative, similar to making a photocopy of a photocopy. To minimize quality loss: convert from the highest quality source available, avoid multiple conversions, use appropriate quality settings (higher bitrates), and when possible, convert from lossless formats (like WAV or uncompressed video) to the final format in one step. For archives, keep a high-quality master file and create compressed versions from that master as needed.
