Master Your Digital Media with VLC


Cross-platform media player VLC is often referred to as the "Swiss Army knife of media applications" for good reason: Not only does VLC play nearly any file you throw at it (you even voted it the best desktop media player), but it can do so much more. From ripping DVDs to converting files to iPod-friendly formats, let's take a look at the four coolest things you can do with VLC and start you on your way to becoming a VLC ninja. Photo by R'eyes.

NOTE: Many of these VLC tricks use the same dialogs, so rather than repeat the same steps every time, I'll be doing a thorough step-by-step once and then highlighting only the differences in the subsequent mini-guides. I'm using Windows in most of my examples, but since VLC is cross-platform, most of the same tricks should work just as well on any platform. VLC has a Streaming and Transcoding Wizard that's supposed to make this process even easier, but it's been buggy for me in all my tests, so I decided to go with the slightly more difficult method detailed below.

Rip Any DVD

You may have thought that you needed some fancy DVD ripping tools to rip DVDs to your hard drive, but VLC can actually rip any DVD with ease. As reader joelena pointed out, since VLC plays the DVD in order to encode it, it can bypass any copy protection. Here's how it works:
  1. Open the Disc and Find the Correct Title: Insert your DVD and open it with File -> Open Disc. We need to find the right title to rip from the DVD, so at this point we're going to preview titles from the disc one by one. To do this, start with 0 as your title number and increment one number at a time until you find the title you want to rip. I've found it's quicker if you choose DVD rather than DVD (menus) at the top of the Open dialog so you only have to wade through actual video.
  2. Pick a Folder to Save the Rip and Name It: Now that you've find the right track, you just need to tell VLC that you want to save it. To do so, tick the Stream/Save checkbox, then click Settings. Here you need to tell VLC where to save the file, so tick the File checkbox and pick a folder to save it to and then give it a name (e.g., My DVD Rip.mpg).
  3. video-and-audio-output-settings.pngDetermine Video and Audio Settings: Now you're ready to tweak the final settings before it's time to rip. Tick the Video codec and Audio codec, then choose the output codecs you prefer. This is really up to you, and if you don't have a preference I've had good results using the defaults described in this excellent VLC rip guide: mp1v for the video codec and mp3 for audio. If you need a specific file format for a mobile device, you may want to choose a difference encapsulation method and codec. Hit OK when you're done.
  4. Rip Away: You've made it. Just hit OK again (make sure Stream/Save is checked) and it should start ripping.

vlc-progress.pngVLC will rip the DVD faster than real-time playback, and you can follow the ripping process in the corner of the VLC window.

Convert Any Video for Your iPod or iPhone with a Drag and Drop Batch Script

vlc-ipod-converter1.pngIf you regularly convert files to a specific file format—say, for your iPod—you can set up a batch file with VLC that will make video conversions as easy as dragging and dropping the to-be-converted file onto the script.

Create a new text file and save it as VLC Converter.bat. Make sure your filesystem is showing file extensions so you aren't saving it as a text file (you don't want to end up with something like VLC Converter.bat.txt). You need to make sure it's saving with the BAT extension.

command-line-options.pngIf you were building the script from scratch, at this point you'd open up the file you just created and paste "C:\Program Files\VideoLAN\VLC\vlc.exe" %1 in the first line. Now you need to get the command line options that describe how VLC should convert the file. For that, you can use the text generated by the Target textbox at the top of the Stream/Save Settings window described in steps two and three of the DVD ripping guide above, which displays the command line options you need for your batch file. Luckily a user at the iPod forums at iLounge already put together a VLC batch conversion script for iPods, so we can just use those settings, which look like this:

"C:\Program Files\VideoLAN\VLC\vlc.exe" %1 :sout=#transcode{vcodec=mp4v,vb=1024,scale=1,height=240,width=320,acodec=mp4a,ab=128,channels=2}:duplicate{dst=std{access=file,mux=mp4,dst=%1.mp4}}

That's a lot of text, but it's just telling VLC everything you would normally tell it in the Settings dialog. The %1 variable will be replaced by the name of the file you drop on the script. Copy and paste all of that text (and only that text) into your batch file and save it. That's all there is to it. Next time you have a video file you want to convert for your iPod, just drag and drop it on your newly created batch script. The script was built specifically for converting videos to an iPod-compatible format, but you can build your own scripts to do virtually common conversions you want.

Stream Media to Other Computers

Now that you're using VLC to rip your DVDs, you've got gigabyte after gigabyte of your videos on your desktop. Rather than copying all of those files to any other computer you'd like to play them on, VLC allows you to stream video over your network or even over the internet.

First, go to File -> Open File. Browse to the file you'd like to stream, and then—like above—tick the Stream/Save checkbox and click Settings. This time, rather than outputting the stream as a file, we're going to tick the UDP box and enter the local IP address of the computer you'd like to stream to. On Windows, you can find your computer's local IP address by opening the command prompt (Win-R, type cmd, and hit Enter), and then type ipconfig and hit Enter.


Once you've got that, enter it in the computer you're streaming from in the text box next to the UDP checkbox you just enabled. Hit OK to accept your settings, then OK again to finish the setup. While you're still on the streaming computer, go to Settings -> Add Interface -> Web Interface.

Now it's time to start the stream on your other computer, and doing so is a breeze. Just open VLC on your second computer, go to File -> Open Network Stream, and—assuming the UDP choice is selected and the port matches the port you used in the setup above (unless you changed it, they should both default to 1234), just hit OK to start the stream.

vlc-web-remote-control1.pngYou're presented with a slight problem streaming the video using VLC this way, namely that you can't control the playback from the remote VLC interface. Luckily you already enabled the web interface, so on the computer you're streaming to, open a web browser and point it to the VLC web interface. If you're streaming over a local network, find your streaming computer's IP address the same way you did with the remote computer's address above, then enter it into your browser with port 8080 appended to the end. Mine looks like http://192.168.1.2:8080. Through the web interface on the remote computer, you can control all of VLC's playback. Handy, huh?

You can stream video over the internet and not just over your local network, but you'll need to either have a static external IP address or assign a domain name to your computer to do so easily. For more details on streaming with VLC, check out Engadget's previous guide.

Play Ripped DVDs

If you prefer keeping ripped DVDs entirely in tact with you rip them to your computer, VLC may not be your tool of choice for ripping. Instead I'd recommend an alternate ripping tool like our one-click DVD ripping solution DVD Rip or one of the other DVD ripping methods we've covered in the past. Once you've ripped the full DVD to your hard, VLC comes in handy once again to play that ripped DVD, menus and all.

DVD-Play2.pngWe've highlighted how to play full ripped DVDs with VLC before, but for an even easier solution, check out DVD Play, a Lifehacker Code original that works as a more attractive front end to playing back full DVD rips with VLC.


We've really only scratched the surface of all the awesome things you can do with VLC, so if you've got a favorite VLC technique of your own (or even favorite encoding settings), let's hear about it in the comments.

Best Free PDF Tools

A PDF tool comes in handy when you need to do PDF documents for any of the following:
  • Merge, split or reorder pages of a PDF file, rotate or crop PDF pages;
  • Add a header, footer or watermark;
  • Encrypt or decrypt PDF documents;
  • Make annotations in PDF pages;
  • Change PDF document properties;
  • Convert PDF to text or images, or vice versa;
  • Other functions.
Top PickPDFill PDF ToolsPDFill PDF Tools is my favorite for its clean and nice user interface with most of the functions covered, such as merge, split, reorder or rotate pages, add headers and footers complete with page numbers, etc.
Watermark can be added by typing in any text such as ‘DRAFT’ for documents to be reviewed, or can be added by a background image in PDF format.
Some additional features are supported such as encrypt and decrypt with security options, reformat multiple pages into one page, PDF form field operations, convert PDF to images or vice versa, and convert PostScript file to PDF.
However, converting PDF to text, making annotations or changing document properties, such as title and author, are not supported in this free software. Instead, they are available to some other programs listed in the lower section.
PDFTK BuilderPDFTK Builder may be used as an alternative. It can merge or reorder selected pages of PDF files at one go. This is a better idea to have merging and reordering of pages done at the same time.
It also supports split, rotate, background/stamp and encrypt features. Besides these, it has no other additional features.
It also lacks a basic function, as available to PDFill PDF Tools, for adding a background text as a watermark to PDF documents. This function is much needed when we need to mark a PDF document as 'Confidential', 'Draft' or in any other text in the background of the pages.
jPDF TweakIf you just need more features, jPDF Tweak will be a good choice but its user interface will not be better than any of the above two applications.
Its merge, split and reorder functions are available under ‘input’ tab with a new filename to be entered under ‘output’ tab.
jPDF Tweak offers rotate, crop, watermark and format multiple pages, change page numbers and chapter bookmarks, and encrypt functions.
It allows adding attachments to PDF documents, setting viewer preference and document properties including title, author, subject and keywords.


Besides the above applications, there are other free programs supporting part of the functions. They are listed below for quick reference.
To only merge and split PDF, you may also look for Gios PDF Splitter And Merger. It allows drag and drop to add documents.
Some PDF to Word ConverterTo convert PDF to text, my choice is Some PDF to Word Converter, which allows removing line breaks and preserves paragraphs with soft returns. It also keeps images but does not preserve hyperlinks for the version under review.
Online conversion from PDF to text through emails is also available free with kool Converter, which preserves paragraphs and hyperlinks in converted PDF files.
Sun PDF Import Extension to OpenOffice.org allows PDF documents imported in Draw and Impress to preserve layout and edit small portion of text. PDF import in Writer is to be developed.
FreeOCR.netFreeOCR.net, which is a scan and OCR (Optical Character Recognition) program, is a good choice to extract text from scanned PDF documents.
To convert text to PDF, OpenOffice.org Writer is a good freeware to export text to PDF. By doing so, hyperlinks or bookmarks are preserved in exported PDF files. To get almost the same good result, kool Converter or Document Converter eXPress offers online conversion to PDF as well.
Alternatively you may install a virtual PDF printer, such as Bullzip, to create a PDF file by printing text or other contents via the PDF printer. By doing so, hyperlinks and bookmarks are usually not preserved in the resulted PDF file. Refer to the category of Best Free PDF Writer for selecting a PDF printer.
PDF-XChange ViewerTo annotate PDF documents, most of the tools do not support it, but PDF-XChange Viewer, covered under the category of Best Free Non-Adobe PDF Reader, does it.
PDF-XChange Viewer also allows highlighting, crossing or underlining selected text, and filling up PDF forms with a built-in typewriter. It is surprisingly more than a viewer!
To make fillable PDF forms, PDFescape is available free via online editing. Other features such as whiteout, insert text or basic symbols are included.
To add attachments to PDF, try PDF Bundle.
To add page numbers, SpeedPDF Page Numberer allows variable formats of page numbers, whereas A-PDF Number has fewer options.
To add watermark, PDF Watermark Creater adds a text as watermark, and SpeedPDF Stamp adds an image as watermark.
To set viewer preference and metadata, BeCyPDFMetaEdit is a good find. It allows editing metadata about author, title, subject, keywords, producer and creator, customizing viewer preferences, bookmarks, page labels, page transitions for slide shows and encryption of PDF documents. TweakPDF is another alternative with fewer options.
To compress a PDF file, try Free PDF Compressor. It allows decompression of a PDF file as well.
To convert PDF versions, use PDF Version Converter for conversion of a PDF file between different versions for compatibility purpose.
