I see this asked often (on other sites) and I have some interest in the topic, so I compiled a little list (just added the last two by looking at the Related sidebar of this question...):
Jing's quite nice, provided you're only recording short clips. And the nice thing is that it can directly upload a recording or screenshot to screencast.com (you get some free space there if you're a jing user)
CamStudio 看起来和工作起来都非常好！ AVI 输出质量很高（音频和视频），运行时我没有遇到任何延迟。 但是 - Flash 转换似乎对我来说根本不起作用？ 我最终得到的是白色或小闪存文件？ （阅读“无用”）有什么建议吗？
OK, as a followup, I got a chance to play with some of the tools suggested.
Wink looked OK, but just didn't cut the mustard. I think the way it "records" is just really inefficient, audio that is layed over the top is also pretty poor due to the gaps the frames produce.
CamStudio looks and works pretty damn good! The AVI output is great quality (both audio and video), I don't experience any lag while it is running. However - the flash conversion does not seem to work at all for me? I end up with either a white or bitty flash file? (read "useless") Any suggestions?
And some more things I have tried (and TBH I will probably stick with):
Using CamStudio to record the screencast in AVI, I had a really good quality output, but it was huge. I needed to get things re-encoded with enough quality to be uploaded to the web and actually readable.
So, I started looking for H.264 encoders and came across this great guide. This lead me on to the following:

我经常（在其他网站上）看到这个问题，并且我对这个主题有一些兴趣，所以我编制了一个小列表（只是通过查看这个问题的相关侧边栏添加了最后两个...）：

仅适用于 Windows 和 Linux (x86)，但请尝试 Wink。 它直接导出到 Flash，因此应该很容易与您的网站集成。
Only works with Windows and Linux (x86), but give Wink a go. It exports to flash directly so should be easy to integrate with your website.
璟相当不错，只要你只录制短片。 好处是它可以直接将录音或屏幕截图上传到 screencast.com（如果你是 jing 用户，你会在那里获得一些免费空间）

好的，作为后续行动，我有机会使用建议的一些工具。

还有一些我尝试过的事情（老实说我可能会坚持）：
使用CamStudio 以 AVI 格式录制截屏视频，我得到了非常好的质量输出，但它巨大。 我需要以足够的质量重新编码内容，以便上传到网络并真正可读。
因此，我开始寻找 H.264 编码器，并发现了这个很棒的指南< /a>. 这让我想到以下内容：
而最终的结果呢？ 我的第一次截屏！（我上传到blip.tv）。
希望这可以帮助！

Hope this helps!
还有 Capture Fox，它是一个 Firefox 插件。
There is also Capture Fox which is a Firefox add-on.
