The software looks for "_v#" and when it finds that tag it associates files together into one logical "asset". Typically we will ask for version tags in the format "_vMMDD". For example, a file delivered on March 19th would have a version tag of "_v0319". If you have to deliver a second version of the same file on the same day we ask that you append a letter to the version tag like this: "_v0319a".
The frame tag is optional, and is used in conjunction with the version tag to replace only a portion of a video. This is helpful to avoid long re-render and delivery times to fix issues that may only be only a short portion of the overall video. See the example below.
The red X represents a bad part of the video, perhaps a render glitch, an unlicensed plugin, or even a mispelled name.
Using a new version tag and the frame tag you can deliver a video "patch" only as long as the portion you need to fix.
The final video plays back seamlessly, even though the patch file was only one second long.
