[Avid-L2] Re: Cinedeck's QT insert editing software to finally ship

 

John is correct, the software tools on the hardware and cineXinsert share the same core code as far as the insert functionality is concerned.  At first release, cineXinsert contains a subset of the hardware's codecs and wrapper support, but full support will quickly follow as we port from PC to Mac.

To answer many of the questions in the thread and some that haven't been asked: 

CineXtools is intended to be a complete broadcast delivery mastering suite, of which cineXinsert is just one part.

Cinedeck's insert edit tool operates on data essences at the lowest level.  It is a true insert, not a cut-and-paste-to-playlist-and-flatten via Quicktime APIs. 

It is not limited to the MOV container. It operates on nearly all common intermediate codecs and wrappers, including Avid-native opAtom, op1A and MOV DNxHD and DNxHR, XDCAM as op1A/MOV, AVC-I including DPP AS-11, J2K (CBR) including AS02, etc, etc.  Eg, the stuff most people deliver.

It allows audio, video and closed captions inserts without affecting any other track, down to a 1 frame fix on one audio track.

It allows almost any content to be used as the insert source, not just another file with the same characteristics.  Eg export a DNx opAtom mixdown from your timeline, or open a MOV with external WAV audio and insert that to a ProRes or DPP deliverable.

The insert edit tool does not need to rewrap for audio edits in any codec/wrapper.  Generally speaking, only ProRes and XDCAM video inserts require rewrapping.  ProRes because it is VBR (except in edit-while-record software) and XDCAM because of the lack of standards adherence in the implementation of the wrapper in most applications.

WRT the inconvenience factor of rewrapping, since insert editing is a destructive process, work should always be done on a copy anyway, and the rewrap is essentially just a copy with equal-sized buckets for every frame.  (referencing the explanation link Terry posted)

The rewrap process serves a useful purpose besides, which is "washing" the MOV or op1A wrapper from other sources to a standard that will pass broadcast QC.


CineXtools already does more than stitch two quicktimes together.:

You can trim or extend, pull or add blacks without going back to the editor and re-exporting.

Audio versioning: You can create one master with all audio, for instance, and instantly create any number of delivery files with different audio layouts including mixed track types.

You can restripe timecode and edit some other container metadata.

You can use cineXinsert as a kind of virtual VTR, much as The Voice uses it with our hardware: create a "black striped file", export mixdowns of each segment of your program as they are completed, insert into the delivery ProRes and watch down/visually QC the final file as the content is inserted.  Make any changes to the final file without a re-export or flatten.  Once the master is complete, make any versions (eg audio layouts or different slate versions) directly from the application.

**Circa IBC features to be supported in the standalone:

*Replace audio tracks from WAV and other standard audio files.

*Replace captions tracks from .SCC and .CAP files.

*Mixdowns in audio versioning (eg stereo from 5.1, mono from stereo, etc., with gain control)

*Batching and queuing.  

*Command line API for automation.

*H264 creation.

**Circa NAB features to be supported

*complete transcoding/rewrapping 

Lastly, anyone who feels inclined may contribute suggestions as to how to make it beautiful.  Feel free to create a mockup in InDesign, for instance.
