best speed to shoot to get slight slow-motion effect in music video?

[Cumie Music]

Hi,

We're doing a minimal video production this Sunday. We want to achieve a slight slow-motion effect for a music video. Shooting with Canon 5D. What speed should we shoot with the camera?

1. 59.98 frames per second (or is it 59.96) and slow it down to 23.98 frames afterwards. OR,
2. 50fps and then bring it to 25 (or 23.98)

The 1st option means we need to lip sync to our song played 2.5 times as fast, which may be difficult/weird.
The 2nd option means 2x as fast - might work better.

Any thoughts on this? Is there a slow-motion standard for music videos? (Coldplay's "Yellow" is at a quite nice speed.)

Many thanks!

Keep it simple: divisible by 2. Your singer has to sing on location to a double-speed audio recording (a bit tricky for the talent) while you shoot twice the frames per second. I haven't actually done this on video, but was quite successful doing it with 16mm film a few years back. It stayed in sync even with long scenes.

Since you're doing a "minimal" production (and I don't know what features your camera has), you always have the option of shooting the picture portion at normal speed, then slowing it down to 50 percent in post. (You should ramp up the shutter speed during the shoot for less motion smearing.) Of course, this latter option duplicates frames and may not give you the best slo-mo effect.

...And since you're in a PAL country, we are talking about 50fps down to 25.

There is NOT a slow-motion standard speed for music videos. Half speed should suffice quite well. Ever thought about doing a test-run first?

Another advantage of half speed is all the notes are the same, just one octave lower.
