In the absence of 60p, How2getSloMo?

[Jaadgy Akanni]

The HD110 doesn't shoot 60p. So my question is: What would be a good and effective way to get professional looking Slow Motion when your only options are 24p and 30p. What's the best software to achieve it?

[Antony Michael Wilson]

Progressive scan at 24, 25 or 30 fps will not produce good results with interpolated slo-mo. No software can really do anything about this. The best solution with your camera is to shoot in the esoteric SD 50 or 60p MPEG2 format. 50p is based on PAL resolution so it will up-scale better to 720p than the NTSC-based 60p SD version.

If you search this forum, there are various discussions on how best to do this with the different NLEs out there.

shoot 60i and run at 50%, in some editors, it will de-interlace and use every other field when expanding...in others, you can get plugins or scripts that will de/re interlace for you...

The best slow motion/time effects software is twixtor...

You can demo the plug in and see of it works for you.

Best.

You can only shoot 60i in standard def with this camera, and as another poster mentioned the camera allows you to shoot 60p in standard def. Why would you want to shoot 60i when you can shoot 60p at the same resolution (really double the vertical resolution)?

Twixtor works great! Just a note on the sample video on their site: This is a New Zealand band and I saw their video on TV her about 6-12months ago. On the big screen the footage looks amazing, I thought they would have used a Varicam etc. The TV feed was only SD but it looked great just like film cranking.

I think shake will do stuff like that too...time ramping and what not with interpolated frames to fill space.

I found the built in speed controls in PPRo2 using Aspect HD work pretty good down to about 70%, without frame blending. 80% speed has a great feel to it.

Thank you guys for providing so much information. You guys are priceless. I'll be trying most of these suggested solutions and see what I like best.

I've found the Timewarp filter in After Effects Pro to be very good at slo-mo, although like all these slo-mo rendering can be very slow.

In fact I've managed to create pretty good ramping with timewarp.

Someone posted some slomo they did with the hd110 and though the colors and resolution looked amazing, I did notice that the motion was still not slow enough. In fact, all the examples I've seen give me that impression. I guess that in order to achieve slower motion the camera would have to be able to shoot 120fps and that's just not happening.

[Antony Michael Wilson]

Software interpolated slo mo often looks fine from 50i or 60i but - with 24, 25 or 30 fps progressive, there just isn't the temporal information to interpolate from. Results from 24p in particular are very disappointing compared to what you'd get from, say, regular interlaced DV. If you own a HD100, there is absolutely no point shooting 60i or 50i when you can shoot SD res 60p or 50p, which will certainly give you better results. As I've said, 50p is based on PAL resolution so it'll look better when bumped up to 720p.

I use the "Frame Blending" feature when changing the speed in FCP. It basically creates a cross fade between each frame which gives it a very smooth motion. It doesn't look bad at all. I use it all the time for my wedding videos.

Here is a short sample of a music video I just shot on the HD100 this way.

Everything you see here except for the intro macro shots of the guitar was shot in 60i and changed to 50% duration....no other interpolating was done. The majority of the video is in 24p, not this type of slomo...what you are going to see is not the final product, but rather just some clips I put into the timeline over the song to see how this looked.

Since the majority of the video is in 24p, why didn't you change duration to 40% instead. I don't know what it would do to the image but it would make it even slower.
