'yadif=mode=send_field' is one way to convert fields to frames at the same frame size and twice the

interpolation filter.
I seek a fields-to-frames filter that does not add cosmetics. In my

They are defined as "int", which can be platform dependant. ffmpeg

Hi there
Can I suggest you post for us the actual commandline that ends up getting
executed, and the output from ffmpeg, at least until it gets down to the
serious number crunching? The problem may be in the way the command is being
assembled.

Hi Laura
OK.
Ordinarily I'd say unless the filenames literally contain your home address and
phone number, don't obfuscate them, because that's exactly the sort of place
the wet can get in.
Still, in this case it does look like it's seeing the input audio and then
writing about 4.5MB of audio
Hi,
The bit I posted was from a shell script so it was posted verbatim. The
variables are being correctly substituted because $SOURCE is found and the
output is at the expected $OUTDIR + $OUTPFX location.
As for the output, see below. I have changed filenames to obfuscated values
because I

Am I missing something simple here ?
The command I am using is based on the example given at

Hi Phil
Just standard Mac OS X preview (click on a mp4 and hit space, it pops up a
preview window and starts playing). Doing so on the source file provides
stereo audio output that is identical to what is seen in Adobe Premiere. Doing
so on the ffmpeg output provides pure silence.

That looks like a different file, judging by your original post:

There should be a file ending with _1080.mp4 in ${OUTDIR}/1080/,
Hmm.
Can you convert a small test file, verify it has the same issue, and upload it
somewhere?
Also, can you install a separate media player such as VLC, and try playing the

Hi Peter
Actually, I have inadvertently already tried it with "another program". The
target for all this work is web playback on video.js.
The lack of audio on video.js is what then drove me back to trying to listen to
