Convert WEBM to HEVC
About WEBM
WebM is a video format sponsored by Google, designed specifically for the web. It is royalty-free and open-source, created to provide a high-quality, efficient alternative to patented formats like MP4 (H.264). It typically uses VP8 or VP9 video codecs and Vorbis or Opus audio codecs. WebM is optimized for streaming and is used heavily by YouTube.
About HEVC
This refers to a raw video stream encoded with the HEVC (High-Efficiency Video Coding) codec, also known as H.265. HEVC is the successor to H.264 and offers about 50% better compression efficiency, meaning it can deliver the same quality at half the file size. This makes it ideal for 4K and 8K streaming. A raw .hevc file must be placed in a container like MP4 or MKV to be useful.

Frequently Asked Questions
Is WebM better than MP4?
For web use, WebM can provide better compression (smaller file sizes at the same quality) than MP4 (using H.264). However, MP4 still has broader hardware support. For maximum compatibility across all devices, especially Apple devices, MP4 is often the safer choice, but WebM is an excellent, open alternative.
What is the main advantage of WebM?
Its main advantage is that it is a completely royalty-free and open-source format. This means developers and companies can implement it in their products without paying licensing fees, which is a major issue with codecs like H.264 and H.265.
Is HEVC/H.265 the future of video?
It is the current standard for high-resolution video delivery (like 4K Blu-ray and streaming). However, its adoption has been hampered by complex and expensive patent licensing. Newer royalty-free codecs like AV1 are competing to become the next universal standard.
Why do I get an error playing an HEVC file?
Playing HEVC video requires either hardware or software support for the codec. Older devices may not have the necessary hardware decoders. You may need to update your media player, install a codec pack, or use a modern player like VLC that has built-in support for HEVC.
