OK: That solved the timestamp problem and created a missing stream.
Does anyone one know the magic option for getting all three streams into MOV.
If I use this to create a DV file (from DVR-DV) it works and creates this file:
ffmpeg -capture_raw_data true -f avfoundation -i DV-VCR -map 0 \
-map_metadata 0 \
-c:v copy \
-c:a copy \
-c copy \
-t 10 output.dv -y
Input #0, dv, from ‘output.dv’:
Metadata:
timecode : 00:00:00:00
Duration: 00:00:10.01, start: 0.000000, bitrate: 28771 kb/s
Stream #0:0: Video: dvvideo, yuv411p, 720x480 [SAR 8:9 DAR 4:3], 25000
kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc
Stream #0:1: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s
Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s
Three streams
If I just change the container to “.mov”
ffmpeg -capture_raw_data true -f avfoundation -i DV-VCR -map 0 \
-map_metadata 0 \
-c:v copy \
-c:a copy \
-c copy \
-t 10 output.mov -y
I get one stream:
nput #0, mov,mp4,m4a,3gp,3g2,mj2, from ‘output.mov’:

I have tried every variation of -map.
If I send the output to pipe and then to a file, all of the streams are their
for DV
If I do the import with Final Cut Pro X then I get this from the file. Also,
FCPX seems to be able to find the original timestamp from when the media was
created.
