We still get lots of questions about the inner workings of Cinedeck’s true, file-based insert editing – what it does and how it’s different from QuickTime Pro. Part two of the discussion addresses the differences and limitations of using something like QuickTime Pro to make changes or fixes in an existing file.

Below is a quick side by side chart of what QT Pro and Cinedeck Insert Edit does:

Key Differences:


The problem Cinedeck addresses is that when it comes to sharing content and delivering finished programs, files simply need to work –  mismatch issues cannot be part of the equation. The time required to manage files is also a critical element in the delivery process.

Cinedeck’s file-based insert edit delivers on both requirements. Files that have been inserted into are standard, fully compatible, flat files. And because the insert and QC process is limited to just the section that needs fixing, the time involved making a fix as well as QC-ing the fix is minimized.

By contrast, QuickTime (MOV) and MXF Op1a are file wrappers that can contain multiple tracks of video, audio and additional data tracks. These wrappers include the ability to add additional content into the package and alter how that content is displayed when playing back, much like editing a playlist or timeline.

In a very simple example, you might have a package that contains a 30-minute video track and you want to change three shots in the video. With these packagers, it is possible to add additional pieces of video and place indicators in the file that tell the player to switch from one track to another during playback.

In the example below, we’ve got a main video track (V1) as well as three additional video tracks (V2, V3, and V4). As you can imagine, this is a non-standard configuration, but allowed within the MOV wrapper structure.

These multi-media containers work well enough for what they are but they are completely different than Cinedeck’s insert edit. File-based Insert Edit uses a straightforward process of physically changing the content in an existing file, by frame accurately overwriting the unneeded content with new correct content. This means that after the inserts, you still have only one video track in your file.

That’s really it… when you’re insert-editing with Cinedeck or cineXtools, you’re still working with a standard file. File-based insert edit digs down into the essence of a file (video essence in the example above) and overwrites new 1s and 0s within the in and out points you’ve selected.
