[FFmpeg-user] Extracting starting timecode info using ffmpeg/ffprobe

[Kieran O Leary]

I am trying to create h264 low res proxies that have a burnt in
timecode which derives from the source video's timecode. I'm making a
bash script that stores the value and uses it as the starting timecode
for the drawtext filter. Can anyone recommend a way for ffprobe or
ffmpeg to always return a timecode start value? I'm guessing that I'm
calling the wrong command?

From some googling, I've had occasional success with the following command:
ffprobe.exe -show_entries format_tags=timecode -of
default=noprint_wrappers=1 inputfile

I've found that I had to use "format_tags=timecode" as
"format=timecode" would not return a value (only mentioning this as
the ffprobe tips page uses the latter in its examples).

Some videos produce a timecode value, some don't, even though my test
videos show a timecode in ffprobe/mediainfo regardless. I was using -v
error as recommended by the ffprobe tips page.

Full output of a file that shows a timecode value, followed by one
that does not return a value.

has produced a much more consistent output. I'd still welcome any

What is the exact command-line that works better for you now, along with some sample output?

The reason I ask is that after trying much I gave up on ffprobe for this purpose and started using exiftool instead. Instead of storing the original starting timecode in the file, I wrote a script that renames video files to "CCYYMMDDHHMMSSFF.ext ", using the earliest timecode reported by exiftool. Apart from being useful for ordering files, subsequent processes can then also use the filename to seed timecode counting e.g. for display purposes during editing, much as you seem to intend.

I'm unsure whether exiftool is available on platforms other than Windows.

Pretty tidy script, that :-).

It appears we're looking for different information - you for a (single) stream-level timecode tag, and me for the per-frame one. I calibrate the camera timecode to absolute time and intend to use frame timecodes for time synchronisation during editing.

FWIW:

1. exiftool's per-frame output looks as follows:
...
Time Code : 17:51:41:22
Date/Time Original : 2014:01:30 17:51:42+02:00
Aperture Setting : 1.8
Gain : 0 dB
Exposure Program : Program AE
White Balance : Auto
Focus : Auto (0)
Image Stabilization : Off
Exposure Time : 1/50
Make : Canon
Recording Mode : Unknown (8)
Capture Frame Rate : 50
Video Frame Rate : 50
Audio Sample Rate : 48000
Time Code : 17:51:41:21
...

2. The file rename script MU_TC2name (the BELL character displays as a round dot):
