Overcrank simulation
Trying to get nice slow motion, had a go today and pleased how it came out, there's a slight loss of quality (I did go overboard a bit) but for a first test I dont think it's too bad,
used 1/1000 on the shutter I've since learned this may have been to much, not sure any thought's? Russ http://www.vimeo.com/1362962 |

frame rate
at what frame rate did you accomplish this at?

If you want really smooth slow motion the best you can really do with 50i is 50% speed, I tested this with a Drifting comp and shot at 1/250, comes out pretty smooth but for something that's not so fast moving like kicking around a soccer ball, probably even 120 would be better. The other option if you want even slower is use Twixtor or similar plugin. I've uploaded an example: (on my end vimeo doesn't play very smooth so might want to just download it) http://www.vimeo.com/1366717 |

I've done a bit of slo mo processing with CS3. Time remapping does a good job down to 50% and sometimes down to 33%. You can see some examples here: http://vimeo.com/1363432
Look at the track shots in between the interviews. AE's pixel motion can do magic or completely lose its mind as you can see here: http://vimeo.com/813381 Go in to 2:00. The water gets pretty chewed up and seems sometimes to run backward. Rendering the HDV footage gives good results, but when you send it to AME it turns a bit gumby. If you do want to send it to AME, you will have to render the time warped footage to an intermediate file, then send it to AME. Many have said that faster shutter speeds will give you better slow motion results. The theory makes sense, but I've gotten some good results shooting 1/60. The night track shot in the first clip is an example. It's a decent tracking shot so the cars look good. I didn't spend much time looking and the background, and really didn't care. Hope that helps. |
