Analysis of video encoding standards H.264 vs H.265

Have you ever encountered such a situation: the picture is very clear when shooting, and the highest quality output is selected when editing, but it becomes blurry when playing? This is probably related to the video encoding standard!

📍Why does the video become blurry?
There are many factors that affect the clarity of the video, including:
✅ Improper selection of encoding format (such as inefficient encoding for high-resolution video)
✅ Insufficient bitrate (over-compression leads to loss of image quality)
✅ Secondary compression on the playback platform (such as social media automatically reducing the image quality)
✅ Insufficient decoding device performance (such as old devices cannot smoothly play high-bitrate videos)
Among them, video encoding standards (such as H.264, H.265) have the most critical impact on image quality and file size.

📍H.264 vs H.265: Which one is more suitable for your video?
✅ H.264 (AVC) - the most compatible standard
Born in 2003
Features:
· Widely compatible with almost all devices and platforms (mobile phones, computers, social media)
· Suitable for 1080P and below resolutions
· Relatively large file size, low compression efficiency

✅ H.265 (HEVC) - Higher resolution, more space-saving
Born in 2013
Features:
· Save 50% storage space compared to H.264 while maintaining the same image quality
· Especially suitable for 4K/8K ultra-high-definition video
· High requirements for hardware decoding, some old devices may not support

📍How to avoid blurry videos?
✅ Choose the right encoding format
· If you are looking for the best compatibility (such as uploading to social media), choose H.264.
· If you are looking for higher image quality + smaller size (such as 4K film and television production), choose H.265.

✅ Make sure the bitrate is high enough
· Too low a bitrate will cause blurry videos. It is recommended to refer to the platform's recommended parameters (e.g. YouTube 4K recommends 50Mbps or more).

✅ Check the playback environment
· Some platforms (such as WeChat and Instagram) will compress videos twice. You can try to play them directly locally for comparison.

✅ Use professional encoding tools
· For example, Xunsiwei encoder supports both H.264 and H.265, and can flexibly choose the best output solution.

📍Conclusion
Blurry videos are not necessarily a problem of shooting or editing. The choice of encoding standards is crucial:
H.264 → Strong compatibility, suitable for ordinary videos and social media.
H.265 → Higher image quality and smaller size, suitable for 4K/8K ultra-high-definition content.

If your video needs to take into account both clarity and smooth playback, it is recommended to choose the appropriate encoding format according to the usage scenario. Xunsiwei encoder supports both standards, whether it is pursuing compatibility or extreme image quality, it can meet the needs!
