Cinelerra is by no means a "light" program. The demands of reading, decoding and playing video on your system can be quite taxing and very resource hungry. Performance (<em>and thus usability</em>) of cinelerra is directly related to the speed, I/O, video and memory of your hardware and to the type of stress that you expect to put on the system. For some users working with audio only or light video formats, a small system might prove sufficient, but to anyone trying to work on DV with several tracks of audio plus a healty set of effects and transitions... it would be completely useless. As a general rule, I would suggest running cinelerra on systems with <strong>not</strong> less than the following specs : 
<p />
<strong>CPU speed</strong> <br>
At least 500 mhz CPU speed, anything less would be useless. I personally run a P4 2.4 Gig CPU, performance is quite satisfactory. 
<p />
<strong>Memory</strong> <br>
Regarding memory.. the more, the merrier. When working with video, a large amount of memory available can help speed up things by avoiding unnecesary disk swaps and keeping material ready accessible. To get a basic idea of what Cinelerra can do you should have at least 256 Megabytes of memory. To really use Cinelerra for larger projects much larger (&gt; 1 Gig) memory space would be required. 
<p />
<strong>Storage</strong> <br>
Storage requirements are based on your particular video editing needs. If you expect to produce long pieces in heavy formats (<em>DV uses about 3.5 Megs per second, or 12 Gigs per hour!</em>) you better get a large (&gt;40 Gig) and fast disk drive. For smaller projects you might get awy with that gig left on the laptop.  Video editing can be quite I/O intensive, for better results be sure to use a fast drive and to <a class="twikiLink" href="ImprovingPerformance">configure</a> it appropiately. 
<p />
<strong>Video Adapters</strong> <br>
Cinelerra uses your systems X server to manage it's display functions, having that in mind a video card with good XFree86 driver support is your best option.  If you are interested on producing a composite signal to send directly on a TV or Video Recorder, make sure your video card of choice supports it. <img src="../../../pub/TWiki/TWikiDocGraphics/pencil.gif" border="0" alt="REFACTOR" width="16" height="16" /> <em>The author uses a NVidia GForce4 MX440se with good results</em>
<p />
<strong>Monitors</strong> <br>
<strong>Multiple Monitors</strong> <br>
You can use XFree86's xinerama features to work on multiple monitor heads. This feature can be a very effective way of increasing productivity, if you have available these resources, I highly recommend them. <br>
<p />
<strong>TV-Out</strong> <br>
If your Adapter supports a TV-Out option, connecting a TV or svideo monitor to it is a great way to view your material as it will be seen on TV screen.<br>
<p />
<strong>Video4Linux</strong> <br>
If you have an analog video camera, or want to grab video from a trusty, old VCR, you need some sort of video grabber.  Video grabbers are supported through <a href="http://bytesex.org/v4l/" target="_top">Video4Linux</a> in Cinelerra. <img src="../../../pub/TWiki/TWikiDocGraphics/pencil.gif" border="0" alt="REFACTOR" width="16" height="16" /> (more needed...)
<p />
<strong>Firewire</strong> <br>
Firewire is the fastest way to download material into your system. Unless you will be downloading all you media materials from a CD or any other pre-captured format (or use an analog video grabber), you will <strong>need</strong> firewire on your system. ( <img src="../../../pub/TWiki/TWikiDocGraphics/help.gif" border="0" alt="QUESTION?" width="16" height="16" /> <em>to learn more about Firewire on linux look at:</em> <span class="twikiNewLink" style="background : #FFFFCE;"><font color="#0000FF">ConfiguringFirewire</font><a href="http://www.ftconsult.com/twiki/bin/edit/Cinelerra/ConfiguringFirewire?topicparent=Cinelerra.HardwareRequirements"><sup>?</sup></a></span>)
<p />
<strong>DV Cameras</strong> <br>
There is an large variety of DV cameras that can be used with Cinelerra. As a matter of fact almost <strong>any</strong> camera that can connect to firewire will work. What is important is to be sure to set the appropiate parameters on the video grabbing system to match the particulars of your camera. <em>(For more information look at the DVCameras topic page)</em>
<p />
<strong>Video capture Cards</strong> <br>
<img src="../../../pub/TWiki/TWikiDocGraphics/pencil.gif" border="0" alt="REFACTOR" width="16" height="16" /> (need more...)  Video capture cards, also called "video grabbers", are supported through
<a href="http://bytesex.org/v4l/" target="_top">Video4Linux</a>.
