youtube-dl and You-Get
youtube-dl is available in Arch Linux community repository. But it does not support some websites. So, it can be complemented with You-Get. Both are surprisingly useful command-line tools.
youtube-dl and Video DownloadHelper
Online video streaming is a very common activity for the current availability of the Internet service. Downloading the video from the web service such as YouTube is one of the common activities among the Internet users.
There are two powerful tools I am using for downloading these videos: youtube-dl and Video DownloadHelper.
youtube-dl is a command-line utility which allows to download various formats of the video available on the webpage; Video DownloadHelper offers similar feature as youtube-dl, yet it is a Firefox addon. Both tools support various websites, not only YouTube alone.
VirtualDub and other video editing software (Linux)
I was using VirtualDub. It is the best (for me). I can simply mark the part of the video that I want to remove, or copy, or move, or duplicate. Moreover, with the plugins, I can also add the subtitles, overlay, and other effects on the video. Though there are less wonderful 3D effects like other software, it is very easy and good to use. There are some limitations, such as it can only load the AVI files. However, codecs of the video is based on what we have installed on the Windows. Thus, we can encode to the smaller size AVI with the codec such as Xvid. There is modified version, VirtualDubMod, yet I still prefer VirtualDub. Another problem is that VirtualDub is only available on Windows. Though, we can use Wine to run VirtualDub smoothly. However, we needs to install the codecs that we need to Wine, so that VirtualDub is able to use the codecs. Because I am using Linux, so I am looking an alternative that can work like VirtualDub. I tried some software. The followings are my little comments on the tested software.
