Quicktime reference files - re-wrap - fps off - speedyrazor - 05.08.2018

Hi, I apologise for asking this here, but I found an old thread by Selur that got things working mostly for me (https://forum.selur.net/showthread.php?tid=162), so thought I would ask here, as you guys are very knowledgeable.

I have been supplied loads of QuickTime reference files (.mov container, with video.m2v and multiple audios.wav). All I am trying to do is re-wrap this into a single .mov file, which works fine using quicktime, for example.
To get the below command working, I need to run the ffmpeg.exe from the same folder as the content.
Using the below command I am able to achieve this, but I have a couple of issues which I can not seem to resolve.

c:\Temp>ffmpeg -enable_drefs 1 -use_absolute_path 1 -i CSP0002377.mov -map 0 -c copy test.mov

The input file is 25fps, but my output file is 26.40fps, and I can't sort out why this is happening.
I also get lots of these errors in the ffmpeg output:

Non-monotonous DTS in output stream 0:0; previous: 227334, current: 227328; changing to 227335. This may result in incorrect timestamps in the output file.

I have attached the ffmpeg outputs for the the initial copy and to show the format of the outputted file.
output1.txt = Initial ffmpeg copy
output2.txt = outputted file
If someone could point me int the right direction, that would be great.
Thanks.

Seems like there is some problem with the time code
What I would try adding '-r 25' to the command line.

Concerning output of ffmpeg for me is:

[mov,mp4,m4a,3gp,3g2,mj2 @ 00000013919db100] st: 0 edit list: 1 Missing key frame while searching for timestamp: 0

block, looks like at some point the time codes stopped and are just repeating 227328 in the input.

In case '-r 25' doesn't help I would also try '-timecode 00:00::00 -timecode_rate 25'.

RE: Quicktime reference files - re-wrap - fps off - speedyrazor - 05.08.2018

Hi Selur, thanks for your quick reply, I already tried the -r 25 option, no difference.
I tried your suggestion '-timecode 00:00::00 -timecode_rate 25' but ffmpeg is not recognising the timecode_rate option, getting 'Unrecognized option 'timecode_rate'.
Just using -timecode 00:00:00:00 also gives the same issues. If I re-encode, then all is good, but i just need a re-warp to consolidate all external files into one stand alone file.

Kind regards.

RE: Quicktime reference files - re-wrap - fps off - Selur - 05.08.2018

Does '-timecode 00:00::00 -r 25' work?

Also try adding '-fflags +genpts'.

RE: Quicktime reference files - re-wrap - fps off - speedyrazor - 05.08.2018

So I just tried:

c:\Temp>ffmpeg -enable_drefs 1 -use_absolute_path 1 -i c:\Temp\CSP0002140.mov -map 0 -c copy -fflags +genpts -timecode 00:00::00 -r 25 test.mov -y

Which gave same results Sad

Attached is outputnew.txt is the ffmpeg output from that.

Kind regards.

RE: Quicktime reference files - re-wrap - fps off - Selur - 05.08.2018

Does it change anything when you use:

ffmpeg -y -fflags +genpts -map_metadata -1 -enable_drefs 1 -use_absolute_path 1 -i c:\Temp\CSP0002140.mov -c copy -r 25 test.mov

instead?

Also try:

ffmpeg -y -enable_drefs 1 -use_absolute_path 1 -i c:\Temp\CSP0002140.mov -c copy -fflags +bitexact -flags:v +bitexact -flags:a +bitexact -r 25 test.mov

This gives:
Option map_metadata (set metadata information of outfile from infile) cannot be applied to input url c:\Temp\CSP0002140.mov -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to.

Also try:

ffmpeg -y -enable_drefs 1 -use_absolute_path 1 -i c:\Temp\CSP0002140.mov -c copy -fflags +bitexact -flags:v +bitexact -flags:a +bitexact -r 25 test.mov

This gives:
basically the same issues, but only have a single audio in the output.

RE: Quicktime reference files - re-wrap - fps off - Selur - 05.08.2018

Ah sorry, try

ffmpeg -y -enable_drefs 1 -use_absolute_path 1 -i c:\Temp\CSP0002140.mov -fflags +genpts -map_metadata -1 -c copy -r 25 test.mov

Gives same result, same errors, but again with only one audio Sad

RE: Quicktime reference files - re-wrap - fps off - Selur - 05.08.2018

Okay, the only first audio might be due to the missing '-map 0'.

What I wanted to archive is that the timecode infos get ignored and new generated, since:

this time code data from stream 0:0 and 0:5 seem to differ.
