Hi Bruce - back to pick up this thread.

Not a silly question; I tried it: iTunes said that file (a .mov file) was
not supported on this iPod (prob. All iPods). I did try an .m4v version I
made with Handbrake (which was still 42+ Mb in size) which took immediately.

I think "compression" is used quite loosely in this scenario, and "they"
really mean "encoded".
Best regards,
Dana

I believe that ability came about in a relatively recent version of 
HandBrake.

2009-08-21 Thread John Niven 

I've used HandBrake to convert DVD's to a format that went onto my iPod nano, 
but I couldn't see how to convert other files. I ended up buying "MP4 
Converter" which seems to do the job, though I have had some audio sync 
problems which I haven't tracked down yet.

Yes, I have Handbrake. I will also give that a try.
Basically looking for something that shrinks video file size for use in an
iPod; surely others have done it?

Try Handbrake.  It does a conversion appropriate for the end

Yes and no. Porting to the iPod is a matter of compression (for things  
like DVD's) and conversion to the correct format. I've tried  
converting some .flv video to .mv4 manually with QT pro and have ended  
up with gigantic file sizes; I clearly don't know what I'm doing...

Send me the youtube ID or URL, I'll see what cosmopod will make of it,  
as it makes pretty well optimized movies. (or you can try cosmopod

 Thank you for responding, Bruce. Let's see if I can be clearer. The movie
was found on YouTube, and was downloaded as (I am sure) a Flash movie via
Perian, then ported to QuickTime. QT's movie inspector says this about the
resulting file:

H.264 (Perian), 512 x 288, Millions
AAC, Stereo, 44.100 kHz
With normal size stated as:
512 x 288 pixels (actual)

What I want to do is "shrink" it, i.e. Do the same to it as say MP3 or Lame
(or yet another lossless compressor - yes, I know MP3 is not lossless per
se, but I'm offering an analogy) does to uncompressed audio - would that not
be the *intent* of porting such a document to an iPod?

> To shrink it down size-wise you'll have to use custom settings.

In QuickTime? What are some good "custom" settings? What are others doing to
media as they prep it for iTunes marketability?

Many thanks,
Dana

It's entirely possible to do this, as QT might well be upscaling the  
video, because convert .mov to iPod gets you specifically  
formatted .m4v files.

Without knowing what the original specs are, it's hard to tell, but if  
it was small (320 x 240 or something) it could well have been smaller  
in the original; .mov files can contain considerable compression as  
well.

To shrink it down size-wise you'll have to use custom settings.

Is this right? (QT -> m4v video question)

2009-08-20 Thread Dana Collins 

I have a QT movie (.mov format) showing a demonstration of realtime
audio pitch manipulation that I want to use for class lecture. The QT
original is at 27.8 MB - thought I'd port it to my iPod Touch for
convenience (I use an Apple A/V composite adapter for overhead screen
projection on downloaded movies), so, in QuickTime, I select "export"
then "movie to iPod", converting the format to .m4v - I noticed it
took an exorbitant amount of time (27 minutes, when the movie clip is
maybe 12 minutes) and then left me with an m4v file weighing in at a
whopping 80.5 MB! I was sure the file sizes would be exponentially the
reverse (isn't m4v a form of encoded "compression" as mp3 is to
audio?).
Does this sound right? Should I be using a different exporting
algorithm?
Thanks in advance,
Dana
