Slow Motion is choppy...anything to do with XL1s?
 
I'm new to the videography arena and I must say, it's a lot more fun than I had thought. I don't know if this has been answered in this forum but I couldn't find the answer to it.

I recently filmed a large project with the XL1s and I edited the video footage. I noticed that some of the footage that I made slow motion, were very choppy.

Why is that? Is it a frame rate issue on the XL1s or is it the editing software? How can I adjust it on the camcorder since I can't seem to find it.

If the scene was fast movement across the screen you may get a more "choppy " slomo.What nle are you using and what type of file are you creating and what are you viewing it on? NTSC or computer monitor?

Welcome aboard DVInfo.net Stan! With all due respect you haven't
searched enough. Slowmotion has been often talked about here
and it boils down to two things:

1. yes your fps is one of the problems. Best (in case of DV) is 60i (interlaced, then 30p (progressive/frame mode) and finally 24p.

2. some programs produce far better results than others

Always shoot stuff that is to be slow motioned in 60i.

I entered the word "slowmotion" into our search engine, and the
first page with results already included such threads as:

This already talks about basically everything you need to know
about slow motion and our camera's. Make sure you check the
"remove/reduce interlace flicker" option in your NLE of choice as
well.

I guess I probably don't understand too much of the video terminology yet, which is why I probably thought the search results made no sense to me. In any case, it seems as though increasing the frame rate is the key.

How would I do that on the XL1s?

Hi Stan,

I hate to tell you this, but you should check the Handbook, this is a very basic function of your XL-1s and there are illustrations to show you exactly where these functions are on the camera. But just to give you a hand - you will find the shutter up and down button on the surface facing the back end of the camera on the manual iris/select protrusion. It is marked "shutter" and the buttons have a + and a - on them.

You can get a fake progressive scan by changing the camera menu settings in CAM. SET UP to "Frame" mode.

I hope that this helps. But really read the manual, there is some stuff about clear scan you should know about as well.

Thanks. When I initially read the manual about the shutter, I had thought it talked about the picture aspect of the camera, not the video. The term shutter reminds me of a camera and I don't reference that with video. I reference "frames per second" with video.

No problem, I see what you mean, that is confusing. Canon mixed some strange photo camera functions into the XL-1s, which I agree, can lead to confusion.

Good luck!

That is correct. To do good slow motion you need more frames
per second. However, no con/pro-sumer camera has multiple
framerates (one HD camera had 60 fps I believe), so you are
stuck with either 24p/30p or 60 interlaced (which is the best to
use to kinda fake it).
