If the conversion 'looks' okay at 24fps, maybe you should try to convert the audio
separately. You might run into sync issues, but it still is worth a try.
You could use Audacity's resampling features to make separate audiotracks, then use
the separate audio feature of DVD-o-matic. The resampling/sampling rate conversion
parameters of course need to be adjusted to match DVD-o-matics framerate handling. But
maybe Carl will find a flaw in the conversion you tried.
When do you need this finished and what is your source footage format?

It is 60 FPS. I can convert it, and it looks good
when on screen at 24 FPS after I do the extra stuff to it, and heck, it even looks great
if I convert it using DVD-o-matic, the sound just...drops in tone.
As for an external player, we have had trouble with using Blu-ray players, etc, in that,
for some reason, some of these private bookings' content (indie filmmakers, etc) will
not work on the players we bought, and I am referring to Sony Blu-ray players, no
knock-offs or anything. This having caused us trouble (and lost bookings), we simply were
told by the company's owner, it must be made into DCP. Using off-the-shelf
Blu-rays/DVDs, I recall we've never had a failure on that, but of course, we don't
have any of those, just indie filmmakers with their burned disks (some pressed, but same
problem, oddly). Media players and computers seem to work fine (most of the time), but
they're inelegant at times.
Thanks for the response!

Subject: Re: [DVD-o-matic] A couple questions...
At 60fps and with a DSS100, I would advise to play it from an external player - PC,
mediaplayer, whatever, through the projectors DVI input.
Not that it isn't possible to do this conversion, but with the DSS100 not being able
to play 60fps and 30fps, there is little chance for a graceful conversion to this target
system. It would need high quality temporal interpolation and, depending on the footage,
may still show judder, smearing or ghosting afterwards.
Is it actually 60p or 60/30i ?

Good day!
One of the theatres I'm involved with is in need of a preview for a special booking
we have upcoming, and the only one we had access to in a reasonable format was in 60 FPS,
but since this preview is to be used with a DSS100/DSP100 which does not like anything but
24 FPS, I was attempting to use DVD-o-matic 0.87 x64 Windows version (I have also tried
earlier versions before now to the same effect) to change it to 24 FPS, and the outcome
was that the audio sounded at least an octave lower. As it is important for our managers
to be able to do this with a minimum of fuss and perhaps as streamlined a process as
possible, I was wondering if there was something I was doing wrong, or if there is a
process to follow for such things. I have found this to be an issue for me before now,
but I was hoping that perhaps it was simply that I have done something in error.
Also, I was noticing that when I'm converting some video into DCP, DVD-o-matic will
change the audio (for 23.976 FPS or 24 FPS, 44.1kHz is adjusted to 48kHz (doesn't seem
to sound odd), for 29.97 FPS to 24 FPS, 44.1 kHz is adjusted to 59940Hz (becomes a lower
octave, which I cannot use, 30 FPS to 24 FPS takes the audio from 44.1kHz to 60kHz
(can't use), and finally 59.94 FPS to 24 FPS changes the audio from 44.1kHz to 59940Hz
(also cannot use - deeper again) ( I would have thought that the 60 FPS would be even
higher than 30 FPS).) Is there a reason that even if the video is at the frame rate I
want, the sound still gets adjusted, and if I'm changing the frame rate, the audio
resample goes up, but the sound becomes deeper? I would have thought the sound would
becoming more shrill, if anything.
Again, I love this program, and the efforts being put into it is amazing, and I'm
willing to assume I'm messing something up. I just would like it if I didn't need
to use a different program to 'pre-adjust' frame rates to get the audio to sound
like the original.
Thank you for all the work you do,
Leslie Hartmier
