how do you call the final "render" of a video
When an editor is finished, the edit is said to be &quot;locked,&quot; or in &quot;picture lock.&quot;  Best practice for file-naming, however, is to use a date string at the beginning of the file name (such as YYYYMMDD_ProjectName.mov), and to avoid descriptors like &quot;locked&quot; or &quot;final.&quot; Otherwise you end up with files named, &quot;TVCommercial_V7_final_final_forRealthistimeFinalLocked.mov&quot;.
A locked edit doesn't mean the piece is complete, either.  Usually, sound mixing, foley, and color come after the edit room.  The video an editor sends to the sound department isn't usually a high-quality render, and might actually be a low-quality &quot;proxy&quot; designed to conserve system resources for sound.  The editor also doesn't pass a render to the colorist; rather, he passes a project file, XML, EDL, or similar, plus an &quot;offline&quot; reference video.  The colorist &quot;conforms&quot; or &quot;re-links&quot; the project files to the camera originals for &quot;finishing,&quot; using the offline reference to check for accuracy.  Once complete, the finished piece is called a &quot;master,&quot; but other copies might be generated in tandem for &quot;archival&quot; purposes, and these are usually the highest quality output.
