Internet Distribution: The Big Squeeze

If you're serious about moviemaking, sooner or later you're going to have to deliver a video for Web streaming. Here's a primer on how various tools succeed at shrinking your work down to byte-sized files.

Web technology may be the great equalizer when it comes to promoting an indie film, but actually delivering your video or trailer for Internet viewing is a different story. It’s hard not to feel cheated, as you convert your work into a tiny file that can be downloaded by zillions of viewers who are too cheap to buy the DVD—many of whom have the attention span of a gnat. But perhaps most frustrating are the numerous software companies flooding the market with different formulas for video compression. The end result? Moviemakers get bogged down with a dozen different codecs (software programs that enable video compression or decompression for digital video) to choose from.

There are software packages that make the process of compressing your video for Internet streaming much easier. I decided to test some of the more popular packages, using the same original DV footage with medium quality output and default audio compressors in order to determine which program offers the most bang for your buck and the best quality for your computer screen.

Video Amphetamines

Use these simple scripts to make your Windows Media and Real Media files start playing immediately. I have no idea how or why these little written commands make Web video load faster, but they do—and a hell of a lot faster at that. Don’t believe me? Try one! Here’s how to use them: Open a word processor on your computer. (I use Notepad, because it’s the simplest.)

Windows Media
Copy the following text exactly, replacing the directories with the ones on your own Website, of course.

<ASX VERSION=“3.0”>
<ENTRY>
<REF HREF=“http://www.yourwebsite. com/videodirectory/Yourfilename. wmv”/>
</ENTRY>
</ASX>

Now save this text document with a “.wvx” extension (myvideo.wvx) and link to it on your Web page.

Real Media
Create the following text in a blank document, inserting your file information. http://www.yourwebsite.com/ videodirectory/yourfilename.rm

Save this file with a “.ram” extension (myvideo.ram) and link to it on your Website.

The Big Three
These first three software platforms are the ones you probably know best. They’re often included with nonlinear editors these days, so you may already be using one or more of them.

Mass Appeal
Windows Media 9, included with most PCs
www.microsoft.com/windows/windowsmedia
There’s little doubt that if you want a video to be accessible to the mass audience, you need a version of it to stream for Windows Media. The compressed video is of decent quality, as is the sound, though I can see very little difference between a file compressed to stream at 256 kilobytes per second (kbs) and one that streams at 512 kbs. A few other gripes about Windows Media: The Mac version of the player tends to be much less stable than the Windows version. Also, the Windows player tends to forget its last size and position, so every time you open a video clip, the player jumps forward and fills your screen. There may be a way to change the default settings, but it will involve some hunting. For copying, sharing and repurposing files, however, Windows Media is great. You can drop .WMV clips right into an Adobe Premiere or After Effects timeline, then resize and apply filters the way you would any AVI clip—although you may have to render to see your results.

Mass Appeal Revisited
Real Media, $19.95 (for RealPlayer Plus)
www.real.com
Like Windows Media, Real Media has become a standard video delivery format. The biggest advantage this software system has over Windows Media is that files play smoothly on Macintosh computers, with similar image and sound quality, using the free RealPlayer application. Also, RealPlayer allows you to jump around the timeline, even as it’s downloading. Real Media clips are difficult to convert, save or manipulate. For videographers, this slows the work process to a halt. Say you want to send an RM clip to an offsite graphics guy and have him add some text or slides. Forget it. Real Media has the end user in mind, not the artist.

Slow Good
QuickTime 7 Pro, $29.99

I’m not a big fan of QuickTime (QT). I know, those are fighting words. But as a reformed Mac user, I’ve never been able to figure out how to and smoothly on my Websites. Even when you select “Fast Start” and save the file in a streaming mode, the QT application still takes about 10 seconds to boot up—an eternity when you’re browsing the Web. I’ve also run into glitches when importing QuickTime files into Adobe Premiere Pro. Unless I import the audio separately, I get frequent audio glitches. My biggest peeve about the Pro version of this software, however, is the way the company handles upgrades. You’re forced to buy a new license for every major upgrade. QuickTime, for my money, is better suited to fullresolution video, where it does something most formats don’t: Allows you to save clips with an alpha layer.

Image Conscious
These tools have a steeper learning curve and slower conversion times, but they can deliver superior quality video streams.

Powerful, If Quirky
Flash 8 Professional, $699.00
www.adobe.com
As Adobe puts it, Flash Player “is the world’s most pervasive software platform,” playing Flash videos on 97 percent of PCs. That may be true, but in my experience, playing Flash files is just as dodgy as any other proprietary software. Like Real Media, Flash video resists efforts to capture, edit or do anything other than watch it. That said, the latest version of Flash is extremely powerful and delivers outstanding quality video. The Flash file created from my DV footage took about twice as long to convert as the Windows Media equivalent, but the final Flash video blows away the competition in clarity, color and watchability. Rendered sound quality was about average. It has far too many bells and whistles for my simple needs, but I’m sure it’s ideal for the full-time Webmeister. Bandwidth misers, beware, however: If you try to make your Flash video files too small—the way YouTube does—you end up with mush.

Secret Weapon
VP3, Free
www.vp3.com/getvp3/index.shtml
Here’s a little piece of software you’ve probably never heard of. It’s a video codec called VP3, made by the same company that makes the software behind Flash 8. VP3 produces video that looks better than most of the major software packages, but it has the added advantage of costing nothing. As part of the “Open Source” project on the Internet, you can download the VP3 codec (code that allows you to play back and create VP3 files). If you want to make your own VP3 videos, you’ll have to use a third-party program to do so. No worries. After installing the codec, just open up QuickTime Pro or another software package and you should see the VP3 option.

All-In-One Suites
These two programs allow you to quickly and efficiently convert video to several different formats.

Studio Workhorse
Sorenson Squeeze 4.3 Compression Suite, $449.00
www.sorensonmedia.com
The latest version of Squeeze is moviemaker friendly. I like the fact that you only have to deal with one screen for most of your video conversion and you can set the “in” and “out” points in your original video. Its interface allows you to log in several clips for batch processing, a major labor-saver, although the time required to render will increase proportionally. Squeeze also offers formats such as MPEG-4, which are becoming more common and offer streaming possibilities that MPEG-1 and MPEG-2 do not. It’s also very handy that this version produces high-quality Flash video that is easy to upgrade with the OnQ VP6 plug-in (the same software used in Flash 8) for even better results. My one complaint is that the program does not offer real time previewing of what clips will look like compressed. In order to see how your final video will look you have to pre-render a short clip.

Swiss Army Knife
Blaze Media Pro, $50.00
www.blazemp.com
The newest release of this conversion package might seem like an odd choice for this article. It’s not aimed at creating Web video, like Squeeze or Flash. Instead, it does a little bit of everything. Most surprisingly, it can create Flash video from your AVI, MPEG-2 or QuickTime files as well as create Windows Media streaming files. On top of that coup (considering the cost), the program boots up quickly and quickly converts back and forth among those standard video formats. The interface also features a simple video editor and a kick-ass audio editor/converter. Without ever reading a manual, you can extract audio from any video clip and convert it into whatever format you want. You can also convert CD audio tracks to WAV files, or burn a CD, or replace the audio in an existing video. Bravo.

As a general rule, you will have to tweak the original video before compressing in order for it to work best in Web streaming format. Levels, such as the contrast and color settings, usually need some adjustments. For example, I often adjust the gamma level of an indoor scene up (making it brighter) by 10 percent. The only way to get it just right is through trial and error—so have some patience.

Now, here’s the dirty little secret about Web streaming: Different compression software tools affect different components of your film, turning some to trash and preserving others. To ensure you don’t lose all of your project’s pro-­ duction value, rank each element of your video in order of importance and align it with the strengths and weaknesses of the software I’ve investigated. You are sure to find a happy medium—and the best compressor for your work. MM
