<h3><a name="Supported_File_Formats"> </a><a name="Supported_File_Formats_"> </a> Supported <a class="twikiLink" href="FileFormat">File Formats</a> </h3>
The format of the file affects what Cinelerra does with it. Some formats replace all the project settings. Some just insert data with existing project settings. If your project sample rate is 48khz and you load a sound file with 96khz, you'll still be playing it at 48khz. XML files, however, replace the project settings. If you load an XML file at 96khz and the current project sample rate is 48khz, you'll change it to 96khz. Supported file formats are currently:
<p />
<ul>
<li> WAV
</li>
<li> PCM
</li>
<li> AIFF
</li>
<li> Uncompresed Quicktime
</li>
</ul>
<p />
      Quicktime is not the standard for UNIX but we use it because it's well documented. All of the Quicktime movies on the internet are compressed. Cinelerra doesn't support compressed Quicktime movies. Most of the Quicktime footage dealt with in Cinelerra is generated by Cinelerra either recording from a device or rendering. The best Quicktime settings to use are JPEG video and twos audio.
<ul>
<li> JPEG, PNG, TIFF, TGA sequences
</li>
</ul>
<p />
      Cinelerra generates a special table of contents file when you render an image sequence. You can either select every image file to load or select the table of contents when the rendering is done. Selecting the table of contents is faster and doesn't fill up the resource window with thousands of images.
<ul>
<li> JPEG, PNG, TIFF, TGA still images
</li>
</ul>
<p />
      When loaded, the image takes up one frame in length and doesn't change the project attributes.
<ul>
<li> AVI with mp3 audio and MPEG-4 video
</li>
<li> MPEG 1, 2 video
</li>
</ul>
<p />
      You need to run mpeg3toc to generate a table of contents for these, then load the table of contents. Mpeg3toc needs the absolute path of the MPEG file. If you want to edit a DVD, find the corresponding ifo file for the program of interest and run
<p />
          mpeg3toc /cdrom/video_ts/vts_01_0.ifo dvd.toc
<p />
<p />
      or something similar. Then load dvd.toc. This allows frame accurate editing where none would be possible otherwise.
<ul>
<li> MPEG program streams and transport streams
</li>
</ul>
<p />
      You need to run mpeg3toc on these just like MPEG 1,2 video. Program and transport streams are structured into multiple tracks. Each track can be video or audio. Each audio track can have 1-6 channels. Cinelerra converts each channel of audio into a track, so for MPEG streams with multiple tracks, the tracks will be flattened.
<ul>
<li> MPEG audio layer II, III
</li>
</ul>
<p />
      These can be loaded directly with no table of contents. Variable bitrate streams may need a table of contents but are playable without it.
<ul>
<li> AC3 audio
</li>
<li> XML
</li>
</ul>
<p />
These are generated by Cinelerra for storing edit lists. They change project attributes when loaded.
