Yeah and speaking of Twixtor, I've been using Motion for the slo-mo stuff: it analyzes two frames and creates a frame to place in between making a clip capable of super slo-mo. That plus shooting at 1/120 at 60 fps I think I'll have some cool effects for the next music video I'm shooting haha</p> http://www.videomaker.com/community/forums/topic/shutter-speed-2#post-71359 Tue, 04 Oct 2011 06:35:27 +0000 doublehamm 71359@http://www.videomaker.com/community/forums/ <p>Ahhhhh Twixtor is what I was looking for.  Loved what the demo could do but still waiting to purchase the full plug-in.  </p> http://www.videomaker.com/community/forums/topic/shutter-speed-2#post-71358 Tue, 04 Oct 2011 06:18:24 +0000 robGRAUERT 71358@http://www.videomaker.com/community/forums/ <p>Even if you weren't shooting for slo-mo, I wouldn't go below 1/120th if you're shooting at 60fps. When shooting 30fps, the shutter is usually 1/60. At 24fps the shutter is 1/48. So it makes sense to shoot at 1/120 when shooting 60fps when you're shooting for real-time playback.</p> <p>For slo-mo, I'd go way faster than 1/120. I've shot with the 7D at 1/1250. We were going for a choppy look rather than preppy for slo-mo, but the footage would work well it slowed down with Twixtor or something.</p> http://www.videomaker.com/community/forums/topic/shutter-speed-2#post-71354 Tue, 04 Oct 2011 03:38:29 +0000 Charles Schultz 71354@http://www.videomaker.com/community/forums/ <p>The faster the shutter speed the sharper the slow motion will look and depending on what is happening in the scene 120 fps might be too slow.</p> http://www.videomaker.com/community/forums/topic/shutter-speed-2#post-71352 Mon, 03 Oct 2011 22:17:39 +0000 doublehamm 71352@http://www.videomaker.com/community/forums/ <p>My guess would be that with a nice fluid slow motion addon it will better calculate the "missing" frames better if there is less motion blur.  </p> http://www.videomaker.com/community/forums/topic/shutter-speed-2#post-71349 Mon, 03 Oct 2011 14:39:08 +0000 Jacob Wayne Bondesen 71349@http://www.videomaker.com/community/forums/ <p>I have been using a Canon T2i and occasionally shoot action scenes that are planned to be editing in slow motion. I was just told by a friend that if I film at 60 fps, I need to keep the shutter speed at 120+ to be able to do the slow motion efficiently with good quality.

But here's the fact, 60i almost always means 60 interlaced fields per second.  That is the same as 30 (actually 29.97 but the difference does not matter) frames per second.  Also, 30p means 30 frames per second.  A frame is a whole picture whereas a field is half a picture.  That's why it takes two fields to make a frame.  Interestingly, the data rate for the two standards is the same.  After all, every 1/30 of a second all the pixels are transmitted regardless of whether they are scanned progressively or interlaced.  Of course, the compression method will change the actual data rate, but that is different consideration.</p> <p>History:</p> <p>I have read blogs where the writer seemed to attach some special or almost magical importance to 24 frames per second.  There isn't.  Originally, when movies were silent, the frame rate was 16 fps.  When sound came along it was found that a faster film speed was needed to record the optical sound track.  Thus, the speed was raised to 24 fps because it was the lowest film speed that allowed reasonable optical sound recording.</p> <p>For TV, 30 frames per second was selected back in 1945 because it reduced the effect of 60 Hz hum bars caused by 60 Hz ripple in the power supplies of early TVs.  Interlaced was selected because early TV screens (cathode ray tubes or CRTs) showed too much flicker when progressively scanned.  </p> <p>Anyway, my point is shoot whatever standard appeals to to and your type of work.  But remember that all analog TVs and the majority of digital TVs default to the 60i standard.  That means no matter what you shot at, the viewer is seeing 60i.  This is not true for video dubbed to film or for video displayed on a computer or special editing devices.</p> <p> </p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63389 Tue, 09 Nov 2010 19:12:56 +0000 roblewis56 63389@http://www.videomaker.com/community/forums/ <p>I often shoot sports and other subjects that have fast<br /> motion.  My camera is a Canon HF11. It<br /> has frame rate choices of 24p, 30p and 60i, the p standing for progressive and<br /> the i standing for interlaced. Clearly the faster frame rate is better so 30p<br /> is preferred over 24p, but is 60i better than 30p? Not necessarily since the<br /> second scan in interlaced occurs later possibly resulting in a shifted image.<br /> Also the Canon manual states: "Recordings made with the [PF24], [PF30]<br /> frame rate are converted and recorded on the memory as 60i". So to help<br /> clarify I carried out the experiment shown in the video by shooting a train<br /> passing in front of the camcorder at about 60-70 mph. In the computer, using<br /> either Adobe Premier Elements or CyberLink PowerDirector the 30p clips show a<br /> single image while the 60i clips show a split image. You can see this in the<br /> freeze frames. However, when uploaded to YouTube the video for 60i is not<br /> split. However, a DVD made from 60i clips show a split image.</p> <p><a href="http://www.youtube.com/watch?v=nxrBd5N4lIw">http://www.youtube.com/watch?v=nxrBd5N4lIw</a></p> <p> </p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63373 Tue, 09 Nov 2010 09:12:56 +0000 mrkinyo7 63373@http://www.videomaker.com/community/forums/ <p> The TM700 appears to be a really good camera with a GREAT Leica lens!  In fact I really wanted the HSC HD700 (I think that's right).  How do you convert the video to stream online.  I'm very new at this but I have IMovie, Premiere Pro CS4 and Final Cut Pro.</p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63372 Tue, 09 Nov 2010 09:09:44 +0000 XTR-91 63372@http://www.videomaker.com/community/forums/ <p>Panasonic HDC-TM700.  Shoot 1920x1080/60p video and then convert it to 480/24p for streaming online (though it does take a long time).</p> <p> </p> <p>I wish my camera's 1080/60i mode had a higher bitrate, as artifacting is much more of a problem with 60i on my cam.</p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63366 Tue, 09 Nov 2010 07:45:06 +0000 mrkinyo7 63366@http://www.videomaker.com/community/forums/ <p>@ XTR-91, thanks for the further clarification on the 60p and 60i.  I would typically shoot video in the 24p mode when I shoot anything other than sports and only use the 60i for shooting sports. This is all good information.  I thought that the 24P was a good quality mode of video.  I have actually shot some of my son's football games in this mode to give it the movie look.  It's cool.  What type of camcorder do you shoot with.</p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63345 Mon, 08 Nov 2010 18:26:17 +0000 XTR-91 63345@http://www.videomaker.com/community/forums/ <p>Just let me say if the 60FPS you're talking about is 60p, then definitely shoot with it, unless you're really trying to conserve camcorder memory.  If you're not, than 60i would be the better option for non-web video.  24p would be for economy purpose or special effect.</p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63334 Mon, 08 Nov 2010 12:54:03 +0000 mrkinyo7 63334@http://www.videomaker.com/community/forums/ <p>Wow!  This is the type of thoroughness that I wish that we could all use when answering questions.  I have a much better understanding of the differences between the two.  I've tried to read a lot about this online but I have to say that no one was able to explain this so that I could understand.</p> <p>Thank you.  By the way what type of stuff do you shoot?</p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63324 Mon, 08 Nov 2010 09:51:44 +0000 Jaimie 63324@http://www.videomaker.com/community/forums/ <p>The FPS business is confusing at best partly because FPS is used in two different ways.  24 FPS generally means 24 frames per second which is a film standard.  60 FPS generally means 60 fields per second which is the interlaced TV standard.  Since a TV frame is made up of two fields, 60 fields per second equals 30 TV frames per second.  Actually, the TV standard is 29.97 frames per second, but that's not important in this discussion.</p> <p>It would seem that there is not much difference between 24 and 30 frames per second, but there is because the TV frames are painted on the screen twice - once for the odd numbered scan lines and once for the even numbered scan lines.  This is where the 60 fields per second comes in, one field contains the odd numbered lines and the other field contains the even numbered.  This is called interlaced scanning and is abbreviated in HDTV as 1080i or 1080 lines interlaced.  In TV, the frame rate is always 30 frames per second.</p> <p>In the case of 24 frames per second, the frame is usually scanned progressively which accounts for the abbreviation 1080p.  This means that the scan lines are painted on the screen one after the other so there is no need to interlace two fields.  </p> <p>Interlaced scanning was originally implemented to reduce flicker on CRT displays, but it has the added advantage of smoothing out motion.  The cost of the smoothing is a reduction in sharpness on fast moving subjects.  That sharpness reduction is due to the fact that two adjacent scan lines are actually created 1/60 of a second apart and the subject has moved during that time interval.  The smoothing comes from the fact you are getting 60 "looks" at the picture every second as opposed to either 30 or 24 in the progressive scan modes.</p> <p>Progressive scan provides a sharper picture of moving subjects because, presumably, all scan line were exposed at the same time.  This is true if the camera has a shutter system that allows that simultaneous exposure, most do not.  Most progressive scan cameras scan every line from top to bottom meaning that the bottom of the picture is captured slightly later than the top.  The result is a slight horizontal stretching of rapidly moving objects.  </p> <p>To my eye on the videos we shoot, neither the slight blurring due to interlacing nor the stretching due to progressive scanning is important because the eye doesn't focus clearly on fast subjects.  But I also think the interlaced scanning produces smoother motion because the 60 fields per second provide more views of the subject (higher sampling rate).</p> <p>If you watch closely, fast motion on film movies is not really smooth nor sharply focused.  Pans are also jerkier than on TV, especially fast pans.  That is neither good nor bad, it is a characteristic of the art form.</p> <p>In the end, I shoot everything in 1080i 30 frames per second because nobody has every told me they wanted jerkier pans etc.</p> <p>Jaimie    </p> http://www.videomaker.com/community/forums/topic/24fps-vs-60fps#post-63323 Mon, 08 Nov 2010 09:09:14 +0000 mrkinyo7 63323@http://www.videomaker.com/community/forums/ <p>I am trying to get a firm understanding of the differences between 24 FPS and 60FPS.  While I don't truley know the difference, I typically use the 24 FPS when I want a movie look and 60FPS for my son's sports and low light situations.</p> http://www.videomaker.com/community/forums/topic/jerky-slow-motion-in-premiere-cs3-shot-60-fps-need-immediate-help#post-40759 Thu, 16 Oct 2008 11:56:45 +0000 Dysfunkshunal 40759@http://www.videomaker.com/community/forums/ <p>I am editing a music video where we shot a good deal of it with the audio mix sped up 100% and then filmed the band at 60 FPS, so that when played back they have that surreal, "singing and playing in real time but looks kinda slowish" feel.  It's been done a billion times and I know you know what I'm talking about.</p> <p>At any rate, when I right click on the clips in the timeline and choose "Speed/Duration", then drop it to 50% (with the Frame Blend option checked), it plays in the source windows at a nice, smooth speed.  But, when I render the clips out, suddenly they playback WORSE, containing jerky motion and it's not at all smooth anymore.</p> <p>Can anyone tell me how to fix this?  I've tried checking off Frame Blend as well but it still looks the same; clunky when rendered.  I think it's odd that it plays back so smoothly when not rendered (I'm assuming my vidcard is responsible for the video playback of unrendered clips?).  Here's some critical data that might help you come up with a solution:</p> <p>Shot On:  Panasonic DVC PRO HD Camera w/ Red Rock Lens<br /> Editing:  Adobe Premiere Pro CS3 (licensed)<br /> Editing Mode:  P2 720p 60Hz DVCPROHD<br /> Frame Size:  960 x 720 (16:9)<br /> Timebase:  23.976 frames/second<br /> Pixel Aspect Ratio:  HD Anamorphic 1080 (1.33)<br /> Display Format: 24 fps timecode</p>
