What you're looking at is the shutter speed (although, video cameras don't have an actual shutter). Your camera only shoot up to 30fps. Ryan M on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-71817 Sun, 23 Oct 2011 18:22:24 +0000 Ryan M 71817@http://www.videomaker.com/community/forums/ I'm also curious on the topic. I shoot with a Canon XH-A1 but mainly at 60fps and for any slow motion shots I integrate the amazing abilities of motion, but with my camera's ability to shoot at ridiculous fps, why not take advantage of it? I want to import high quality slow motion around 1000fps (my camera goes up to 15,000 according to the dial settings) but when i import video and slow it down, it looks just like normal 60fps shots on FCP. Do I have to import it at a different setting than normal film? Thanks!

I would like to burn a SD DVD in 29.97 fps, but some of the videos contain are in 12fps or less, so that if I burn the dvd in 29.97, those video will play faster than the original. I would like to know, is there any way I can burn the dvd in 29.97 but wouldn't affect the contain video's quality and frame rate? Thanks in advance for help, really thanks! robGRAUERT on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58984 Tue, 25 May 2010 04:21:27 +0000 robGRAUERT 58984@http://www.videomaker.com/community/forums/ if it works for ya, then it works for ya... anindya49 on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58976 Mon, 24 May 2010 22:38:23 +0000 anindya49 58976@http://www.videomaker.com/community/forums/ Rob, thanks for the motion compensation tip! The two half frames in 60i are taken 1/60th of a second apart; they do not refer to the same instant in time. The deinterlacing simply converts each half frame to a full frame by filling in the missing lines. That's a better approach than trying to guess the whole frame. For a 60p output, both the half frames are used to produce two full frames (the full temporal resolution of 60i is used). For 30p output, one of the half frames is discarded, while the other one is converted into a full frame, or some kind of frame blending is used. 60i itself is not the same thing as 30p because the even and odd fields in 60i are shifted in time with respect to each other. The advantage of this approach is that only the spatial resolution is interpolated, not the temporal resolution. So there are no motion artifacts. When I play back the converted progressive file frame by frame, there are 60 frames in each second, and they are all distinct, as they should be. Even without the motion compensation setting the video looks very good (that's why I didn't bother turning the other things on). I'll turn it on to see if there is any improvement. A similar technique is available for JES deinterlacer, described in its documentation. Btw there are other places on the web which suggest this (search Compressor 60i to 60p): <a href="http://forums.skateperception.com/index.php?showtopic=154566" rel="nofollow">http://forums.skateperception.com/index.php?showtopic=154566</a> Anyway, I've used this and the (40%) slow motion is very smooth and high quality. Of course, the best approach is to shoot 60p if available. I do that on my HMC150 which has a 720 60p mode. I use the 60i to 60p conversion for my HF200. robGRAUERT on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58964 Mon, 24 May 2010 15:26:56 +0000 robGRAUERT 58964@http://www.videomaker.com/community/forums/ "Dragging a 60i file onto this with produce a true 60fps progressive video. The idea here is to convert each interlaced frame into a progressive frame, so that you have 60 unique frames per second." An interlaced frame consists of 2 fields, which is why 60i is 29.97. If you were to only de-interlace, you get 30p. The setting you create de-interlaces and creates a 30p to 60p conversion at the same time. You are pulling an extra 30 frames out of no where (not that optical flow in Motion doesn't do that). Also, when converting 30 to 60, you also need to change the Rate Conversion setting to "Best (High Quality Motion Compensated), which you forgot to mention. anindya49 on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58954 Mon, 24 May 2010 13:29:21 +0000 anindya49 58954@http://www.videomaker.com/community/forums/ The field output needs to be progressive, the FPS has to be set to 60 and the deinterlace filter needs to be on. Actually there's not much difference between the two Prores presets apart from the interlaced check box in video compression settings, which I think controls the output? As long as this is correctly set any one of the two presets can be used as a starting point. Here are the steps I use for 60i to 60p (this is true 60i and not 24p over 60i): <ul> <li>Open Compressor.</li> <li>In the Settings window, choose Apple->Other Workflows->Advanced Format Conversions->Apple Codecs.</li> <li>Choose one of the Apple Prores 422 codecs (normal quality should be fine). Right click it and choose "Duplicate".</li> <li>A copy of the codec should now appear under the Custom heading. Select it. </li> <li>In the Inspector window, click the Encoder tab. Click the Video Settings button.</li> <li>In the Standard Video Compression Settings dialog, make the following changes: Motion->Frame Rate->59.94, uncheck the interlaced checkbox under Compressor. Click Ok.</li> <li>Next click the Frame Controls Tab. Click the gear button to activate the tab and then turn Frame Controls on. Set Output Fields->Progressive and Deinterlace->Better.</li> <li>Give the preset a new name like "60i to 60p" and save it.</li> </ul> That's all. Dragging a 60i file onto this with produce a true 60fps progressive video. The idea here is to convert each interlaced frame into a progressive frame, so that you have 60 unique frames per second. I use this often on 60i footage and it produces 60p, not 30p if you do it right. Using Cinema Tools I've got beautiful slo-mo without using Motion. It's very possible. JES deinterlacer can also do this, but I prefer using Compressor. Of course, if the original is 24p, then Motion is the only way. jsanti3 on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58933 Mon, 24 May 2010 06:35:30 +0000 jsanti3 58933@http://www.videomaker.com/community/forums/ Awesome feedback guys!

Here is an example of the summary tab after you are done:" Deinterlacing 60i does not give you 60fps. It will still only give you 29.97 - it will just be progressive, and it won't even slow down that much once you conform in CInema tools. The "ProRes 422 for Progressive Material" is for a progressive SOURCE. So if he wants to deinterlace and transcode to ProRes, he should use "ProRes422 for Interlaced Material," turn on Frame Controls, and set up the Frame Controls pane for deinterlacing. But like I implied, it's pretty much pointless to deinterlace 60i to get slow mo out of it. You're better off bringing it into Motion and using Optical Flow anindya49 on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58929 Mon, 24 May 2010 02:34:24 +0000 anindya49 58929@http://www.videomaker.com/community/forums/ Just to be clear, shooting at a higher frame rate and then playing the footage back at a lower frame rate produces very smooth slow motion. If instead you just use FCP's speed controls to slow the footage down, it will be jerky as the intermediate frames are not there anymore. One solution is to use Motion to generate the intermediate frames (see article referred to by Earl above). However, as with any other automation, your mileage may vary. Motion attempts to fill in the missing frames. The technology is somewhat similar to a feature found in some new LCD TVs where the motion in 24fps movies can be smoothed out by the TV (It creeps me out, but some people seem to like the effect). anindya49 on "Slow Mo in Final Cut Pro" http://www.videomaker.com/community/forums/topic/slow-mo-in-final-cut-pro#post-58928 Mon, 24 May 2010 02:08:35 +0000 anindya49 58928@http://www.videomaker.com/community/forums/ If you are shooting in a progressive 60 fps format, just change the fps from 60 to 24 in Cinema Tools. Instant slow motion. If you are using one of the interlaced 60i modes, use Compressor to de-interlace it to 60p. Then use Cinema Tools.

From what I hear it seems people shoot at a higher frame rate and then import the footage at a lesser one. Is that true? If so, how do you do that in Final Cut Pro? Example shooting at 60p and then bringing into 24p. Outside of Final Cut Pro, is there any other software you need to have to accomplish this effect? Can someone please explain this?

I'm using Premiere Pro v7.0 I've taken a few clips that are .mov files. In quicktime the videos look beautiful and display at full frame rate. However, in Premiere, instead of displaying or saving at the correct frame rate of 29.97, it thinks the frame rate is 2.99 fps. The strange thing is is that the duration of the video is correct, so if I try to manually adjust the frame rate with the 'Interpret Footage' it shortens the duration of the clip proportionally. Another odd thing is that Premiere shows the video track frame rate to be 29.97 in the clip properties but then assigns a frame rate of 2.99 for the whole thing. Here's what it shows for one of them: Type: QuickTime Movie File Size: 151.08MB Image Size: 848x480 Pixel Depth: 24 Frame Rate: 2.99 Audio 44100 Hz - 16 bit - Mono Total Duration: 00;04;08;15 Average Date Rate: 622.55KB / second Pixel Aspect Ration: 1.000 Quick Time Details: Move contains 1 video track(s), 1 audio track(s) and 0 timecode track(s) Video: This movie appears to have DROPPED FRAMES.

I do throw training (jav, baseball, football) and do not feel the 60 frame per second rate is as useful as some of the higher rates I see on TV. Does anyone know good cameras for this type of use and what they might cost? Probably going to be alot higher than what I paid for my Canon ZR 65mc! and yeah, price will be an issue! TIA
