编码器是一种压缩算法，它直接决定了视频的压缩效率和画质。其中，H.265 (HEVC) 是目前实现高效压缩的关键。相比于上一代的H.264，H.265拥有 高出25%到50%的压缩效率 。这意味着，使用H.265编码的300MB视频，其画质可能接近甚至超过使用H.264编码的600MB视频。因此，一个高质量的“300MB MKV”文件，其内部核心大概率是H.265 (x265)编码。
Achieving a 300MB file for a two-hour movie requires aggressive video encoding. This is typically done using two main standards: 1. H.264 (AVC) mkv 300mb
While the quality isn't ideal for a 65-inch TV, 300MB movies look perfectly acceptable on smartphone screens. How to Play 300MB MKV Files mkv 300mb

To help you get started with the right settings for your specific video project, let me know:
: Under the "Video" tab, select H.265 (x265) . Check the "Avg Bitrate (kbps)" box and set it to roughly 350 to 400 kbps to target a final size of around 300MB for a standard length film.
