Slow Motion Video.
-
Haven’t seen much video on PI, but thought I’d post this. I was testing a premiere plugin called Twixtor that generates slow motion footage from stuff I shot with my 7D, and it worked okay. There are a few glitches, but all in all I was impressed with the plugin.

Hmmm…. the embed thingy doesn’t work.
Andy,
You put the following url in between the tags (its not clear how to so I’ll improve that) eg
[vimeo]http://www.vimeo.com/17429358[/vimeo]Which gives you :)

To be honest, we don’t really do video on the site, its more a still photography forum for photographers.
Its been mentioned by 1 or 2 in the past but I’m not sure that there is enough interest to warrant any dedicated
forum etc for it… anyhow, thats enough from me :)Only getting to view it now. Very very interesting Andy !
Well worth watching. Not sure what I can offer in terms of improvements though.Would like to see more !
just wondering why you would do a slow motion test and not capture in camera and instead rely on post production plug in which creates glitches, it doesn’t seem to make much sense. or was it purely to test the plug in.
I can’t afford a slow motion camera, but love the look, so this is a combination of my 7D running at its fastest frame-rate (a measly 60fps, but my other cameras only run at 25 or 30), and the plugin doing what it can with that footage. It was a worthwhile experiment. Where all of the objects in the shot are moving at similar speeds, the plugin works quite well, so I know I can use it in those circumstances. It’s only when things move at different speeds, or when things move too much between frames that the effect looks jumpy.
makes sense now, didn’t know that was another of the 7d’s limitations, another reason I wont be going dslr as a moving image camera for some time yet.
What do you shoot on? 7D is great for standard stuff, but the few things it can’t do bug me. Also, I just got an external monitor, and it makes all the difference. So handy being able to see what you’re shooting again :)
Hey Andy,
Great post!
I have a question for you. When set in PAL format the max setting on the 7D is 50fps and in NTSC it’s 60fps. What’s the major difference in these 2 settings other the the 10 fps :roll:
Is there a downside to NTSC as we all live on PAL land? Suppose you can always output in whatever format you like?
Cheers,
John.Hi John,
The main differences between PAL and NTSC are to do with whether the footage is interlaced. NTSC footage records a frame in two stage, first it records every second line, then it records the other set of lines. PAL records a straight frame in one go. It’s very easy to convert PAL to NTSC, but slightly harder to convert NTSC to PAL without losing any quality. Most TVs in Europe play PAL and NTSC, while in the US, most TVs only play NTSC (or at least that used to be the case). On the internet, neither PAL or NTSC are used, but most video file formats used uninterlaced – progressive images, which is closer to PAL. PAL is also closer to cinema format with the frame rate being 25 (movies are usually shot at 24fps).
For best results, have a think about where your video will need to play, and shoot in as close to that format as possible. The more you convert, the more you degrade quality. For this video, it was just a test that would end up on the internet, so while PAL would have given me a slightly better picture, I was willing to convert from NTSC to a progressive file for the sake of those extra 10 frames per second.
Anyone else shooting video here? Maybe others have something to add?
