Then why are you "slumming" here? :-)

###### some settings and notes ######


using mpeg4 as output codec for ffmpeg results in a a fourcc of FMP4 and the camera says "file failed". Using msmpeg4v1 results in a FOURCC of MPG4. Using msmpeg4v2 results in MP42. msmpeg4 results in DIV3 mencoder appears to let you override the fourcc.






Note that undocumented "-vtag M4S2" lets you set the fourcc. with "-vcodec msmpeg4v1 -vtag M4S2" there is no file failed message but you get a blank screen/audio when playing.
This mostly works:


time ffmpeg -i hedwig_and_the_angry_inch.mpg -f asf -b 1680 -s 640x480 -r 29.97 -aspect 4:3 -vcodec mpeg4 -vtag M4S2 -ar 11025 -ab 44 -ac 1 -acodec adpcm_ms /tmp/CLIP0054.ASF



There is some green and pink garbage which probably represents mpeg opcodes that aren't understood. Intermittent crashes, more frequent when using TV out. Some crashes are sticky and persist between playings; playing a short clip that was recorded on the camera often helps to reset. Sometimes the camera hangs and the batteries have to be removed.


With "-vtag M4S2" the mpeg4 codec works (sort of) but not the msmpeg4, msmpeg4v1, msmpeg4v2 codecs.


The manual for the ISDV2 mentions default settings used with ArcSoft MediaConverter:
320x240, ASF, 2.0Mb bideo bitrate, 128Kb audio bit rate, 25 fps.

You don't think a newbie forum would help? Then maybe the newbies
would assist each other and pick up a thing or two.

The regular use forums would be better. They would have a higher
percentage of useful posts, questions and answers with some value to
readers.

We were all newbies once, it's just a stage you go through, there's
nothing condescending about it - but hopefully we learn eventually.

It's one of the problems with these all-in-one software types
that are popular now.
It's a black box and you don't learn anything. Now you feed in an avi
or an flv, and out the other end comes an ISO of all things.
Which you're supposed to write to a dvd, and Hey Presto! play it
your dvd player. But what if it doesn't doesn't play?
You never saw, or even knew about the intermediate mpeg 2 files,
so you can't test them to see if they play in VLC or WMP -
in short you're completely lost and you never learned anything.
It would be funny if it wasn't so sad.

And to top it off, they think the ISO is a video file
and they want to know how to "play" it.
