推荐答案

请注意，仅使用一些zip算法(在Java中相对容易实现)压缩它不会对您有太大帮助.尝试自己压缩文件. (如果 did 使文件更小，则很可能已经是视频文件格式的一部分了，不是吗:-)

Note that simply compressing it with some zip-algorithm (relatively easy to do in Java) wouldn't help you much. Try compressing the file yourself. (If it did make the file smaller, it would most likely already be a part of the video-file format, wouldn't it :-)

如果要压缩视频，则必须以较低的比特率/较低的分辨率或类似的方式重新编码.

If you want to compress the video, you have to re-encode it with a lower bit-rate / lower resolution or something similar.
