Mac OS 有什么视频转换软件吗？只想转变格式 不想动内容。

[WesleyNZ]

任何原视频的参数都不想动，只是因为只有 mp4 才能预览，无奈必须转换 flv mkv 到 mp4 格式。

[WesleyNZ]

@jxie0755 我试过了 不支持这个功能

[dingdangnao]

我看懂了，你是希望原视频除了后缀什么都不变？怎么可能？

[daozhihun]

videoproc，5 分钟以内不用掏钱，不然要付费了（可以一次性买断）

[WesleyNZ]

@dingdangnao 为什么不可能？

[WesleyNZ]

@daozhihun 你确认可以只换容器转换吗？

[aptupdate]

不知道自带的 iMovie 能不能转

[daozhihun]

@WesleyNZ 我不懂你是什么意思，你可以下载下来试用看看，5 分钟以内的视频免费试用，先看看合不合要求好了，我不懂什么叫做换容器转换

[cwbsw]

@WesleyNZ 写个脚本可以直接在 Finder 里右键执行，不比专门找个软件方便得多？

[realkenshinji]

ffmpeg

[WesleyNZ]

@cwbsw 怎么写？我不会啊问题是

HandBrake 省心

[mxalbert1996]

所以楼主是不准备解释到底想要什么「文件本身的信息」了？

[newage126]

handbrake 被杀毒软件查出来有毒

[jxie0755]

@WesleyNZ Handbrake 里面可以选择参数与源相同的。

[WesleyNZ]

@jxie0755 如何选择？！？求解。。

[WesleyNZ]

@mxalbert1996 我家里网络有问题 手机 imgur 微博， 电脑 imgur， 微博 都不让上传图片，我买了 V2EX 会员上传图片到现在还没给我充值，我已经付款了。。

[WesleyNZ]

@jxie0755 我查了一下只能说你是放屁了。。‘
@CuSO4 不可以实现这个功能我再次强调
@newage126 绝对无毒，你自己编译试试看

What's the problem with Handbrake?
When you're using Handbrake to convert from one container format to the other (i.e. MKV to MP4 in your case), Handbrake will re-encode the video. See also the respective feature request that would have enabled video passthrough:

「「「「「「 Sorry, adding video passthrough is not planned. HandBrake is designed to be a video transcoder. It wasn't designed to allow passthrough.」」」」」」」

看这里 ⬆️

So, anytime you're changing containers with Handbrake, your video is going to get re-encoded, which means it a) takes time and b) may introduce quality loss.

Do I have to re-encode? Couldn't I just swap the container?
Since passthrough is not possible, ask yourself: Do I need to re-encode? If you only want to change the container from MKV to MP4, you usually don't need to encode anything, you just change the "wrapping" around the video. This doesn't lose quality, and it'll be a much faster process.

You can swap containers easily with FFmpeg – you just have to tell it to copy the video and audio streams:

@WesleyNZ 说实在，没能帮到你很抱歉，但是你说我放屁的话，是不是不太妥当？

[CuSO4]

@jxie0755 #38 暴躁楼主，别人帮忙他的回复完全没有礼貌。让他自己玩蛋去吧。（白眼）

@CuSO4 请看一下 21 楼 他已经建议过无数次了 麻烦你看清楚！
