[Cin] UPD2: Interesting info about EDL I found ....

Wed Oct 30 23:38:04 CET 2019

ah, found this in release notes:

5.1 Release Notes for changes from 07/01/2017 to 07/31/2017 for these builds
Removed Reel Name, Reel Number, Time Code Start from Asset Info in Resources & Preferences.

so, I can conclude this commit broke CMX3600 support, if there was any ....

Hm, time to load CinCV :}

Ok, CinCV doesn't load xml from CinGG correctly, but at least creates something .....

cat '/dev/shm/DOG.edl'
TITLE: Cinproj   FORMAT: CMX 3600 4-Ch
001 cin0000  V    C        00:00:00:00 00:01:10:06 00:00:00:00 00:01:10:06
002    BL    V    C        00:00:00:00 18518:31:06:00:01:10:06 00:01:10:06 18518:32:17:01

So, reel_name was important for this feature to work. 

I'll open feature request (low prio)

I actually tried this 'EDL export function, with simple one track dog file.

Hm ...

I can't see any info about file used?

cat '/dev/shm/dog/dog/dog.edl'
TITLE: Cinproj   FORMAT: CMX 3600 4-Ch
001    BL    V    C        00:00:00:00 00:00:17:09 00:00:00:00 00:00:17:09
002    BL    V    C        00:00:00:00 00:00:11:13 00:00:17:09 00:00:29:07

according to 

https://developer.blender.org/T53615

this file format at least initially included reel_name (is this info still around in CinGG?)
but late tools used other  way to identify source files ...

------------------copypasta------

Description
In 2.79 The file path parsing gives an error. Open an EDL file, hit 'Refresh Reels' - gives the error: "File not found". However, this bug isn't in 2.77.
Cross dissolve transitions are added to the entire following clip and not just the transition duration.
'Import EDL" script will give a non-descriptive error if there are space characters in the reel name. The in EDLs the reel name column is always 8 characters wide and can contain spaces.

"* From clip name:" should(also) be used to id filenames. All Pro NLEs(Ex. Avid, Premiere, Final Cut and Davinci Resolve) are using this comment to locate source files(full file name with extension, but no path). Once mentioned here: https://developer.blender.org/T48146 Only archaic EDL importers like the one in Lightworks only uses the reel name for file id, however in Lightworks the time code and reel name must be embedded in the source files (ffmpeg can read/write this). But as mentioned most other pro EDL importers have the option to ignore embedded time codes and use the comments to id filenames(instead of reel name).

Ex. EDL file from Premiere:
TITLE: 4tin2tin
FCM: NON-DROP FRAME

001  AX       AA/V  C        00:07:16:20 00:07:21:12 00:00:00:00 00:00:04:17
* FROM CLIP NAME: 4tin2tin.mp4

002  AX       V     C        00:07:16:20 00:07:20:12 00:00:00:00 00:00:03:17
* FROM CLIP NAME: 4tin2tin.mp4

003  AX       V     C        00:07:20:12 00:07:20:12 00:00:03:17 00:00:03:17
FCM: NON-DROP FRAME
003  AX       V     D    025 00:37:45:21 00:37:47:12 00:00:03:17 00:00:05:08
EFFECTS NAME IS CROSS DISSOLVE
* FROM CLIP NAME: 4tin2tin.mp4
* TO CLIP NAME: 4tin2tin.mp4

004  AX       V     C        00:37:46:21 00:37:48:12 00:00:04:17 00:00:06:08
* FROM CLIP NAME: 4tin2tin.mp4

005  AX       V     C        00:37:46:21 00:37:47:12 00:00:04:17 00:00:05:08
* FROM CLIP NAME: 4tin2tin.mp4

------copypasta ends-----

Apparently this summer interesting framework OpenTimelineIO was opened, with (buggy?) CMX 3600  module:

https://opentimelineio.readthedocs.io/en/latest/tutorials/otio-plugins.html

also 

https://github.com/iluvcapra/pycmx

pycmx
The pycmx package provides a basic interface for parsing a CMX 3600 EDL and its most most common variations.
Features
The major variations of the CMX 3600: the standard, "File32" and "File128" formats are automatically detected and properly read.

While translating (attempting to translate few still untranslated things) CinGG
I found interesting note about EDL export. Intially I assumed it only works with 
some long-obsoleted device/soft, but today I found this page (while looking at timecode feature):

https://eyeframeconverter.wordpress.com/mlt2edl/

MLT2EDL
NB. Since Shotcut version 16.06 this script is not needed anymore. Shotcut can export EDL files natively: https://www.shotcut.org/blog/new-release-1606/ 
Mlt2edl is a python script for converting Shotcut mlt files into ex. Blender (v. 2.72 beta or higher) friendly CMX 3600 EDL files. The converted EDL files will also work in Lightworks and Resolve. Mlt2edl is based on the Kdenparse python script by Will Riley.

Because CinGG (and original Cin) should be able to output exactly this EDL (???) format ... This mean she automatically compatible with "Lightworks and Resolve" and Blender, too??

Anyone can test this?
