Burning timecode into mov file

bartom
Hi,
could anyone tell me the command in ffmpeg to burn the timecode track of a mov  file onto the video?
(I've installed the latest version of ffmpeg that has support for the ProRes codec).
Thank you very much for any hint.
Best wishes

Burn the track? If you meant burn the timecode onto the video, see
timecode and rate option in drawtext filter:
http://ffmpeg.org/libavfilter.html#drawtext

If you meant to add a timecode code track in the mov, this is not
supported at the moment: http://ffmpeg.org/general.html#Timecode. You can
extract the current timecode from the tmcd track with ffprobe though.

..at the moment.... How tantalising is that ;)

Re: Burning timecode into mov file

In reply to this post by Clément Bœsch
Hi,
Many thanks for your answers and  your help.

 I tried using ffprobe to extract  the timecode stream as you suggest, but ffprobe doesn't seem to be able to decode the timecode stream. I ran the command:

ffprobe -show_streams  test.mov
 
but I get the message 'Unsupported codec with id 0 for input stream 2' (the timecode stream). Do I need to specify some other option so that ffprobe can decode the timecode stream?
Thanks again for any help

T. Bar

The complete output of my command ffprobe -show_streams  test.mov is:

Re: Burning timecode into mov file

bartom
Thanks for your reply and pointing this out. I see now.
I ran the  command:

ffprobe -show_packets  test.mov

and in the  output of this command containing all the packets, there is only a single packet of the timecode stream (all the rest are audio and video packets). This is the packet of the timecode stream:

[PACKET]
codec_type=data
stream_index=2
pts=0
pts_time=0.000000
dts=0
dts_time=0.000000
duration=6371400
duration_time=2548.560000
size=4
pos=39369995192
flags=K
[/PACKET]

Is this normal, that there is  only one packet in the timecode stream? I had a total misconception concerning the timecode track. I thought that for each video frame, the timecode stream has a frame  storing a different timecode value. But I suppose I was wrong: each video file has only one value in the timecode track: the TAG:timecode=18:27:15:17 that you pointed out, which is the start timecode, and that's it?

Many thanks again.

This is normal for ffmpeg, which only supports a "first frame" timecode
and a rate. In fact some containers (mov, mxf and gxf?) support frame by
frame timecode tagging allowing for discontinuities. However there are
very few applications that can make use of this, and in particular every
NLE I have come across works the same as ffmpeg.

Re: Burning timecode into mov file

bartom
Ok. Thanks a lot for the clarification.
Yes, I'm dealing with mov files that can have discontinuities in the timecode. I have to preserve the discontinuities because they correspond to the real time, that  is what I want to burn onto the video.
I wanted to avoid using final cut pro, but I guess its the only option.
Many thanks again.

Clément, now, after some months, it seems supported:

"MOV X X"

but I can't make it work, and I've been searching and studying all day...

The command I'm trying to apply is:
ffmpeg -i <input.mov> -acodec copy -vcodec copy -metadata timecode=15:14:13:00 <output.mov>
but I get nothing...

Do you have some advice?

Thank you very much

Try -timecode 15:14:13:00?

If it doesn't work, please paste the command line and full output, as well
as the output of ffprobe output.mov.

Clément, I've tried the command
ffmpeg -i STD_0022.MOV -timecode 15:14:13:00 -acodec copy -vcodec copy std_0022_tc.mov
but I don't think I have any success. The timecode doesn't show up in QT 7.x nor in FCP.
I don't have ffprobe and I currently don't have the tools to compile it, since I understand there's no binary available for download. In the meantime, I've called the resulting MOV file with ffmpeg -i and this is the result:

        movenc: add timecode track support.

And:

    June, 7, 2012, FFmpeg 0.11.1

(and actually 0.11 is even older, .1 being just a bug fixes release)

So I believe your version is too old. Note that we highly recommend our
users to use the latest development version, which you can get on
https://ffmpeg.org/download.html.

You seem yo be looking for a Mac OS build, and unfortunately the static
build provided by tessus seem indeed limited to the release versions. I'd
suggest you to look into the wiki for detailed instructions:
https://ffmpeg.org/trac/ffmpeg/wiki/MacOSXCompilationGuide

MrGralich
>So I believe your version is too old.

Clément, thanks for your help, but the 0.11.1 is exactly the version that I've used, as reported in the output I had attached ("ffmpeg version 0.11.1-tessus Copyright (c) 2000-2012 the FFmpeg developers
  built on Aug 16 2012 18:49:35 with llvm_gcc 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)
 ").
So I must be giving some incorrect command, I'm afraid.

For the ffprobe, I've found the windows build and used it, but the output is exactly the same as the one returned by "ffmpeg -i" command.

I appreciate your help

That's what I was saying, 0.11.1 is the latest release but it is too old
anyway.

Re: Burning timecode into mov file

Greg79
Hello Guys,

sorry for opening this issue once again, but I'm trying to deal with quite the same problem.
I'm quite new in this field. Let me try to give you an overview.
I have several video stream from several synchronised cameras which I would like to save. For a later analysis I need to jump to a specific frame in each of these videos. To do this I thinking to use the timecode.
As far as I understood it correctly, that what I'm looking for is the "burnt in timecode" (BITC) which is keyed into each frame content, right?
The normal timecode is keyed in the header of GOP, which will allow me to do a kind of estimation, right?
The general question is, does only AVI or other video container, like MOV allow BITC?
It this feature related to the codec I'm using, as well? Which codecs are supporting BITC?

Thank you in advance.
Best Greg

All codecs accept BITC.
it is, as you stated,  burned into the video, so it  becomes part of it.
The encoder would not know if it's digits or regular video.
(aso you can never remove it...)

Hi Bouke,

thank you very much, your post was quite enlightening.
Nevertheless, I still don't know if I'm able to use BITC to address a particular frame.

For example does ffmpeg provides access to a particular frame by addressing it via BITC (give me frame at 00:04:12:42). If so, how to do it?

Best Regards and many tnx in advance.
Greg

Yes, manually while looking at the image :-)

Nope, FFmpeg has no OCR (that would be required)
If you want to adress specific frames, be aware that you need a proper codec
to do frame accurate searching.
check the -ss options to go to specific frames

very cool,

tnx a lot.. this was really enlightening!
A very last question, this method is not supported by all formats, right?
Is there a list with the supported formats somewhere?

cheers
