 The Ticket Tracker is a web platform tracking process of video recording and ingest sources and video encoding progress. It guides users through manual processes like editing and checking and provides an API for scripts doing post processing and encoding. The Ticket Tracker is a web platform tracking process of video recording and ingest sources and video encoding progress.

 +## Ticket Properties
  
-== Concepts+see [[properties]]
  
-The C3 Ticket Tracker enables the (semi-)automated recording, editing & release of multilingual videos. In order to complete a release successfully, certain project settings must be configured and a few of the state transitions must be operated manually: +## Trackerfahrer Scripts
- +
-=== Ticket types and hierarchy +
- +
-One of the really good features of the C3 tracker is that propertyies are inherited through the hierarchy: +
- +
-* Project settings (Conference or Series) +
-    * Meta ticket (Parent with Fahrplan-ID & -Metadata) +
-        * Recording ticket (Language, etc) +
-           - Main encoding ticket (MP4) +
-           - additional encoding tickets, e.g. WebM, MP3, Opus, SD formats, etc. +
- +
- +
-=== Ticket states +
- +
-For each ticket type, the tracker has a predefined set of states, which can be enabled and disabled on an per project basis. Here is an example workflow with only one manual `checking` step: +
- +
-{{drawio>c3tracker:states}} +
- +
-Now let's look into the steps done by worker scripts +
- +
-==== Step A: Recording Scheduler +
- +
-[[https://github.com/crs-tools/crs-scripts/blob/master/scripts/script-A-recording-scheduler.pl|script-A-recording-scheduler.pl]] +
- +
-Schedules and transitions tickets from `scheduled` to `recording`. Adds padding and optionally filters by room. Skips opt-out events. +
- +
-- **Inputs**: CRS ticket in `scheduled` state +
-- **Outputs**: Ticket moved to `recording` or skipped +
-- **Notes**: Uses `CRS_ROOM`, `Record.StartedBefore`, and `Record.EndedBefore` filters +
- +
-==== Step B: Create virtual project files +
- +
-[[https://github.com/crs-tools/crs-scripts/blob/master/scripts/script-B-mount4cut.pl|script-B-mount4cut.pl]] +
- +
-Mounts raw video segments via FUSE. Checks and sets cut marks, stores metadata like duration and framerate. +
- +
-- **Inputs**: Ticket in `recording` → `preparing` state +
-- **Outputs**: FUSE mount created and cut marks optionally stored +
-- **Notes**: Supports DV and TS formats +
- +
-==== Step C: Cut Postprocessing +
- +
-[[https://github.com/crs-tools/crs-scripts/blob/master/scripts/script-C-cut-postprocessor.pl|script-C-cut-postprocessor.pl]] +
- +
-Validates cut marks, adds intro/outro clips if defined, and calculates cut durations. Fails tickets with incomplete data. +
- +
-- **Inputs**: Ticket in `finalizing` state +
-- **Outputs**: Ticket updated with durations and metadata +
-- **Notes**: Verifies intro/outro file paths and presence +
- +
-==== Step D: Encoding +
- +
-[[https://github.com/crs-tools/crs-scripts/blob/master/scripts/script-D-encoding.pl|script-D-encoding.pl]] +
- +
-Runs encoding tasks from job XML. Skips if Voctomix is detected. Supports VAAPI acceleration and logs execution times. +
- +
-- **Inputs**: Ticket in `encoding` state +
-- **Outputs**: Encoded media file(s), ticket state updated +
-- **Notes**: Uses CRS::Executor and task-type detection +
- +
-==== Step E: Postencoding  +
- +
-[[https://github.com/crs-tools/crs-scripts/blob/master/scripts/script-E-postencoding-auphonic.pl|script-E-postencoding-auphonic.pl]] +
- +
-Runs audio processing and remuxing. Can optionally delegate to Auphonic for audio leveling and rendering. +
- +
-- **Inputs**: Ticket in `postencoding` state +
-- **Outputs**: Updated audio tracks and metadata +
-- **Notes**: Supports audio hash checking and production reuse +
- +
-==== Step F: Upload +
- +
-[[https://github.com/crs-tools/crs-scripts/blob/master/scripts/script-F-postprocessing-upload.pl|script-F-postprocessing-upload.pl]] +
- +
-Uploads processed files to the target via ssh from encoder/storage to [[intern:server:releasing.c3voc.de]]. Can skip uploads based on host config. +
- +
-- **Inputs**: Ticket in `postprocessing` state +
-- **Outputs**: Files pushed to publishing target +
-- **Notes**: Validates file presence, honors opt-out and skip-hosts +

-== Usage during event +
- +
- +
-=== Task: Cut +
- +
-see [[operation:cutting]] +
- +
-{{c3_tracker_-_schnitt_mit_kdenlive.mp4}} +
-* [[https://www.youtube.com/watch?v=K-KHbAcTo9I|Usage video YT link]] (german) +
- +
- +
-* TODO: [[events:cccamp15:pp]] integrieren +
- +
-=== Task: Check  +
- +
-see [[operation:checking]] +
- +
- +
-Ticket types and states +
- +
-* Parent tickets for each [[:schedule|Fahrplan]] entry +
-* one recording ticket for each parent +
-* several encoding tickets, one for each format – e.g. MP4 HD, MP4 SD, WebM, MP3, Opus +
- +
- +
-== Project setup +
- +
-  * Create tracker project (you can also clone a matching project to have prefilled properties) +
-  * Import schedule.xml +
-  * Set all master tickets from staging to staged via mass-edit +
-  * Adjust project properties, recommendations: (full reference at the bottom of the page) +
-  * Compare project properties with previous instalment of the same event +
- +
-see [[c3tracker:setup]] for more details +
- +
-=== User Roles +
-User accounts can have different roles depending on what the user should be able to do: +
-  * "User" - can cut and edit tickets +
-  * "Restricted" - can only use already defined actions and can't define new actions +
-  * "Superuser" -  can edit profiles and (re)import fahrplan +
-  * "Admin" +
- +
-more details on https://github.com/crs-tools/tracker/blob/master/src/Config/AccessControl.php +
- +
- +
-== Recording +
-Files that should be handled by the tracker (input files) should be named as follows: +
-<code> +
-  <room>-YYYY-MM-DD_HH-MM-SS.<extension> +
-</code> +
- +
-Files need to be placed in directories according to the room name +
-<bootnote> +
-Note that names are stripped from frab and combined with the word "saal" which means i.e. "startrampe 23" results in "saal23". THIS WILL BE FIXED IN THE FUTURE. +
-</bootnote> +
- +
-Naming for intro and outro: +
-  * Intro <frab-id>.dv  +
-  * Outro: outro.dv +
- +
-== Postprocessing +
- +
-=== Cut +
-The cutting process requires start and end marks. The tracker accepts frame numbers. If your player does not show frame numbers you can approximate with the formula +
-<code> +
-seconds * 25 +
-</code> +
-assumed you have 25 frames per second. Note that this means you cut per second not per frame !!! +
