Let me throw this open to all,
With regard to Super 8 sound film cartridges, of which I have loads still in the freezer, is it recommended to shoot at 18fps or 24fps? Does the 24fps help to eliminate the sound jitter, or is there really little difference? Up to now I have been using 18fps, simply to save on film, as there’s obviously a 25% saving to be made – or is this false economy?
When compared to a tape recorder, the 18fps represents a speed slightly slower than the 3-3/4ips, whilst the 24fps would be slightly quicker than this. So it is unlikely that there would be much improvement in actual sound quality. You have to virtually double the speed of magnetic audio tape to get any appreciable improvement – frequency response etc.
Any thoughts or discussion on this subject would be gratefully received.
Thank you.
Dave.

Hi Steve,
I know exactly what you mean about the panning. When shooting Regular 8 or Super 8 (silent, of course) I always pan at 24fps, then switch back to the 16fps (reg 8) or 18fps (sup 8) for all other types of shots. This has a two-fold advantage.
1. The blurring and any jerkiness is kept to a minimum, and
2. When the whole film is projected at the 16 or 18fps throughout, the panning scenes are extremely smooth, and, although slower, this does not seem to detract from any impact, as the scenes are much clearer.
If the idea of the panning scene is to create blurred jerkiness, then fine to use the slower speed throughout.
But - sound film is a different matter - you can't keep changing the projector speed!!
As you rightly say, projector noise is also a consideration. Dave.

Thanks Joe, Transfer to video is not an issue for me, as I intend to keep everything on film. The cameras I use are both Bauers; an S409XL and an S609XL with microprocessor. In your opinion, do these cameras justify 24fps? I use John Schwind for my processing. The other thing is, I don't have a separate projection room, so projector noise at 24fps is a bit of a factor.
In view of the above, would you still think 24fps is worth doing?
Many thanks,
David.
