FAQ

Video Format FAQ

Common questions about video formats, codecs, and choosing the right format for your needs.

What's the difference between a container and a codec?

A container (like MP4, MKV, AVI) is like a box that holds video, audio, and metadata. A codec (like H.264, H.265, VP9) is the compression method used to encode the actual video data inside the container. For example, MP4 is a container that can hold H.264, H.265, or other codecs.

Which video format is best for web use?

MP4 with H.264 codec is the best choice for web use. It has universal browser support, good compression, and works across all devices. WebM with VP9 is also excellent for web but has slightly less compatibility. Avoid AVI, MOV, or WMV for web use.

Should I use H.264 or H.265 (HEVC)?

H.264 offers better compatibility and is supported everywhere, making it ideal for web and social media. H.265 provides 25-50% better compression but has limited support on older devices and requires licensing fees. Use H.264 for broad compatibility, H.265 for storage efficiency when compatibility isn't critical.

What's the best format for 4K video?

For 4K video, H.265 (HEVC) in MP4 container is often best due to superior compression - essential for large 4K files. However, if compatibility is more important than file size, H.264 in MP4 works well too. AV1 offers excellent 4K compression but isn't widely supported yet.

Which format should I use for archival storage?

For long-term archival, use lossless formats like ProRes, DNxHD, or even uncompressed video in MKV containers. These preserve maximum quality for future editing. For space-efficient archival with good quality, H.265 in MP4 or MKV containers provides excellent compression while maintaining high quality.

What about newer formats like AV1?

AV1 offers excellent compression (30% better than H.264) and is royalty-free, making it very promising for the future. However, encoding is currently slow and device support is limited to newer hardware. It's excellent for streaming services but not yet practical for most general use cases.
