What are the differences between video codecs?

Video codecs are algorithms that compress and decompress digital video. Common codecs include H.264, H.265, and VP9. H.264 is widely used for its balance of quality and file size, while H.265 offers better compression but requires more processing power. VP9 is often used for streaming on platforms like YouTube.

Which codec is best for streaming?

For streaming, H.264 is still the most popular due to its compatibility and efficiency. However, H.265 can provide better quality at lower bitrates, making it a good choice if your audience has the hardware to support it.

Are there any free codecs I can use?

Yes, there are several free codecs available, such as VP8 and VP9, which are open-source and widely used for web streaming. Additionally, AV1 is a newer codec that offers excellent compression and is also free to use.

What about the quality differences between them?

Quality can vary significantly between codecs. H.265 generally provides better quality at lower bitrates compared to H.264. VP9 also offers high quality, especially for high-resolution videos, but may require more processing power.
