Slow Motion

I'm new here and to the DVX 100B. I have a question about slow motion. The book & DVD talk about creating slow and fast motion in camera, but nothing about doing it in post. Are there reasons for doing it this way that I'm overlooking? Generally, I don't make those decisions until editing (for effect, to sync with music, etc.).

Shooting 24p doesn't prohibit creating slow or fast motion in post, does it?

Tnanks,

Bill,

You can certainly do slowmo with 24p in post. However, it will require some frame blending or interpolation to get it done. This can range from very bad quality in some NLE's to very good quality using RevisionFX Twixtor.

It's better to know in advance which shots you intend to slowmo, and perhaps shoot 30p (slowed frame-to-frame to 24p in post for a slight slowmo), or 60i, slowed to 24p in post for a slower smoother slowmo.

For slow or fast motion, you may want to think about shutter speeds (make the shutter faster for slow mo, slower for fast mo).

Slow Motion

I had a question in the same vein as above.

I just shot a music video in 24p and thought about what scenes I wanted in slow motion ahead of the shoot. For those scenes I shot in 60i. I believe it was the F4 setting because the exposure and white balance were as close to the 24p setting as possible.

Now I'm editing in Final Cut Pro and I'm slowing the 60i scenes down to about 80%.

The footage doesn't blend well with the 24p footage.

Do I need to do something else, ie: uncheck the frame blending box, ect.

Can it be done in Final Cut, or do I need another program?
 
Bill,
After Effects has a feature called time warp which does a very nice job with slow motion, even works well with 24p footage.

Grasshopper,
Are you editing in a 24p timeline? If so then slow your 60i footage down to 40%. If you're editing in a 29.97 timeline, then slow your footage down 50%

Thanks for the help! I consider myself more of a storyteller than a technician. In the past, I've decided on the cuts then used an editor to make it happen. Now that I have my own camera, I want to learn the whole process from top to bottom. So, if I ask novice questions from time to time, it's because in a sense, I am.

Snapsnack: I shot a documentary in and around Syracuse while I was living up there. I had access to film equipment from SU. The film had it's world premiere at the newly refurbished Palace Theatre last April and has aired twice on WCNY. Small world, huh?

Are you ready for the snow?

Bill
 
Snow? Does it snow here? Yeah I'm already planning my trips to Vegas to visit my brother. Anything to get through the winter.

Congrats on the documentary, next time I'm at the WCNY studios I'll hit em up for a copy. If you have any more questions feel free to PM me. Enjoy your warm Texas weather, I'm off to buy some shovels.

I believe my timeline is 29.97. I was hoping not to have to slow the action down that much. It's mostly walking.

But I guess that will blend better.
Thanks.
 
I think I made a post about it somwehere else but I'll post it again.

I have a method of doing slow-mo on the DVX that produces exceptionally high quality footage but requires FCP and compressor to do so. The pdf for it is here and the results are here.

Good luck mang.
 
Thanks everybody! I still doubt I'll pre-plan slow motion shots, but if I do, I now have a good idea of what I need to do for the best results.

I'm really enjoying the DVX 100B and I like the look and feel of the shots I'm getting.

I saw some amazing slomo of a wedding here done with timewarp... dont remember who posted it thou...
 
The best way of going about doing slow motion is this: first you have your footage transferred to HDCAM. Then you have the HD transferred to 35mm film. After you've done that, you have the 35mm optically double printed. After that you transfer it to MiniDV, campture the footage, and edit away.

Deff Agree with Josh... I have been playing with Twixtor for past few days and it's fantatsic, very sophisticated plug in in terms of slow mo (bleding frame)....

My best,
