Any Super 8 cameras with 25 fps ?

[christoph]

Maybe someone else can explain why this method of transfer could cause problems with audio because I just don't see it.

well imagine you film a clock and record it ticking for 10 seconds:

the film will record 240frames at 24fps
the audio will record 10 seconds
the projector will project 240 at 25fps.. that takes 9.6 seconds
the video camera will record 240 frames at 25fps, again 9.6 secs

import the whole thing into your computer and try to match the ticking and the moving hands of the clock and you will see why you'll have to change the audio (you can also change the video of course, but quality suffers and it takes more time)

hope that cleared things up.

I see what you are saying when it comes to trying to sync audio and film recorded simultaneosly Christoph, but he just wants to add a music track to the video (I'm assuming it's just a pre-recorded music track and not one that was recorded while filming). This shouldn't present any problems, should it?

nah, that's no problem whatsoever.. i was assuming we were talking about shooting a music video because otherwise music doesnt really sync to anything. but these days hardly any music clip has shots that are longer than 2 seconds in it's final edit anyway.. so it's a pretty moot point too (besides, you wouldnt really want to change the audio speed in a music vid i guess ;).

Ok so - wait

If you get a song & the aritst sings along with a mini disc playing the song in the backgraound of the shoot just for the artist to mime.
The s8 cam shoots 24 fps ( no sound obviously ) - we then speed up the footage by 1 fps to 25 fps on the projector - we would then have the artist running a bit ahead of the track when we come to import the original cd track into the nle ?
we theorectically have to speed up the music track to fall right in line with the artist mime - or does 1fps to minor to notice ?

I understand that we dont normally see the artist singing along 100 % of the video but - when the artist does - it would definitely be ahead of the original recorded track - unless off course :roll: Im completely wrong
For example - if we were to shoot sound also at 24 fps & match that with the original recording of the music track ( off cd ) - would that be in sync or off ?
I guess Im confusing the hell out of this issue now - sorry ? :oops:

yes

well, it depends on how long you show him without a cut. i'd say 3 seconds are no prob, more than 5 and it's beginning to become noticable. then readjust sync for the next cut.
but in this case you would probably want to slow down the video, and not speed up the audio, since the speed of the music is important for a song.

no, you're right :)

you cant use the word fps for sound really (thats FRAMES per second.. audio doesnt have frames). with analog audio, you had different running speeds, so you could say i'm recording with 5cm/sec (5cm of tape) and play back with 6cm/sec (that will change the pitch though, remember when playing LPs on the speed for single records, ie 33rpm at 45rpm?). but todays digital recorders are all cristal synced, so you record 10 seconds and then you play them back it's still 10 seconds, no matter which speed you have chosen with your camera. (it's dead easy to change it in your NLE though).
but if you were to record a live concert, shoot 24fps with the camera, transfer at 25fps and use the live audio it would drift out of sync as well, just like the ticking of the clock does in my example above.

i am getting a nizo that is crystal synced to 25fps if anybody is interested. i think it was the last model made
