Hi All
I'm a new user of Transcode, I'm not trying to do anything overly
involved just transcode (not re-encode) DV in a QT container into DV in
a Type1 AVI container (or type 2 I don't really care as long as Windows
Media Encoder can read it and I believe unlike VfW encoders that because
WME is Dshow based it can read type1 and type2 AVI wrapped DV, anyhow)
tcproble showed:
# tcprobe -i part1.mov
[tcprobe] Digital Video (NTSC)
[tcprobe] summary for part1.mov, (*) = not default, 0 = not
detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 4:3 (*)
frame rate: -f 29.970 [25.000] frc=4 (*)
no audio track: use "null" import module for audio
(NB. It misidentified the res here as QT shows that .mov as being DV 720
x 576)
Which suggested to me that it couldn't identify the audio. So I tried
exporting the QT/DV as DV stream from QTPro and transcoding that to
type1 AVI/DV:
# transcode -P 3 -i Part1.dv -y dv -o part1_dv.avi

Which suggested the Audio needed re-encoding to match the DV standard (I
thought basic DV was lax about the audio format, oh well) so setting the
passthrough to 1 (hopefully letting it do whatever it needs to the
audio):

So there's something wrong with the video that the output encoder desn't
support? Does anyone know if there's something nonstandard about my DV
stream? Or, contrary to what the error says is it having trouble with
the audio export because the default it's plumped for seem a little odd
TIA for any light that can be shed.
