Video file manipulation

Image
By
Many times I have downloaded a movie and when opened it is in French or Russian or any other language I do not know. Most people outright delete the file. I thought no. In most of the cases the video quality is superb while it is difficult to find  the same movie in english with the same quality. The reason is obvious. However, as it turns out that the big uncle does not care about the prints in English which are very low quality. So, I thought that I can download them, extract their audio and plug the mp3 into the audio track of the high quality print in different language. And here's how to do it. These methods work only in Linux (sorry Windows users).

To extract audio from avi(or mpg) file :

ffmpeg -i file.avi -acodec copy output.mp3

acodec does a direct copy of the audio track without involving any encoding into mp3.

To add the audio to avi file :

Open avidemux and load the video file (with nn-english audio). Say yes to all pop-ups. Then goto the menu Audio-> Main track -> external file -> select your file i.e. output.mp3 .

Change the audio drop-down box (below video in left hand side) from COPY to MP3(LAME).

Save the file with a different name.

Fastest way to send multiple drafts from gmail

By
People claim that the fastest way to send multiple email drafts is to use Gmail IMAP with email client like Outlook or Evolution or Thunderbird. But I have found this is not true. Because Thunderbird and Evolution etc. email clients treats the drafts as emails still to be edited. So it is not just simple select all and hit send. Each email draft has to be opened and sent separately. That is a lot of clicks and mouse movements, wasting precious time and energy. I have a better solution which involves minimum keystrokes and mouse usage. Efficiency booster technique for sending emails. If someone is feeling adventurous and want to try it from the Gmail interface itself, here's how to do it in the fastest possible manner. It involves using the mouse once. Select the first draft. Gmail would open a new email box and put the cursor inside the box to write. Press TAB once to go the Send button. Press ENTER to send. Now Gmail sends it and the box is gone but the highlight goes to the last

Changing the font size of section headings in LaTex

By
You have several ways to do so: 1.- A direct redefinition of \section: \makeatletter \renewcommand\section{\@startsection{section}{1}{\z@}%                                   {-3.5ex \@plus -1ex \@minus -.2ex}%                                   {2.3ex \@plus.2ex}%                                   {\normalfont\large\bfseries}} \makeatother 2.- By means of the titlesec package: \usepackage{titlesec} \titleformat{\section}{\large\bfseries}{\thesection}{1em}{} 3.- By means of the sectsty package: \usepackage{sectsty} \sectionfont{\large} source : http://www.latex-community.org/forum/viewtopic.php?f=4&t=3245   Now, I would explain the titlesec package a bit more (because it seems easier to me and with more options) : To change the section fonts with this package put the following lines in the preamble - \usepackage{titlesec} \titleformat{\ section }{\ large \ bfseries }{\thesection}{1em}{} Options available are- a> Font size - \normals
