v3.4.7.12
Although 'Clever' includes '-dn' (no data streams) during export, this parameter
does not remove a time code (TMCD) data stream.
I need 'Clever' to have the ability to properly remove TMCD; that's all.
It is as simple as adding '-write_tmcd 0' to your ffmpeg cmd.
Is that too much to ask?
To know why this is extremely important, please read on ...
TMCD (Timecode) is a specialized Data stream type that carries timing metadata for video files,| Stream Type | Code | Description |
|------------|------|-------------|
| Video | 'v' or 'V' | Video streams. 'v' matches all video streams,
while 'V' only matches video streams that are not attached pictures, thumbnails, or cover arts|
| Audio | 'a' | Audio streams. Includes all types of audio tracks in the media file|
| Subtitle | 's' | Subtitle streams. Contains text-based subtitle tracks|
| Data | 'd' | Data streams. Can include various types of non-media data embedded in the file|
| Attachments | 't' | Attachment streams. Used for embedded files like fonts, images, or
other supplementary content|
primarily used in professional video production and editing workflows.
Characteristics
---------------
Usage| Attribute | Description |
|-----------|-------------|
| Stream Type | Data stream ('d') |
| Codec | 'tmcd' (timecode) |
| Purpose | Stores precise frame-level timing information |
| Common Containers | QuickTime (.mov), professional video formats |
------
A timecode stream provides frame-accurate timing information that helps synchronize video
frames, in professional video editing and production environments.
It contains:
- Starting timecode
- Frame rate
- Frame count
- Precise temporal references
Typical Use Cases
- Professional video editing
- Broadcast and film production
- Maintaining frame-level synchronization
- Precise video navigation and editing
Issues
-------
Some applications (ex: mobile platforms) have compatibility problems with files containing TMCD streams.
Detection
----------
When inspecting a file with a timecode stream, you'll see an entry like:
RemovalCode:Stream 0:2(und): Data: none (tmcd / 0x64636D74), 0 kb/s (default)
---------
You can remove a TMCD stream using FFmpeg:
Code:ffmpeg -i input.mov -c:a copy -c:v copy -write_tmcd 0 output.mov
