Slow Motion and Frame Rates?

Hi I have a Sony NEX-VG20EH camera and it has an adjustable frame rate. I have put the frame rate on 8000 and recorded some footage. When i load it into Premiere it is still showing as 50.00 fps. I want to do some slow motion stuff but when i slow it down to 10% it is still quite "jumpy". Any ideas?

While many cameras DO offer the ability to "overcrank" for a short duration, such as to capture a golf swing in slow-motion, I looked at the specs for your camera and don't see that feature listed.
Raising the shutter speed means that the shutter is open for a shorter duration during the exposure of each frame of video. At slow shutter speeds, fast motion will look blurred on a freeze frame or during slow playback, because the subject moved quite a bit during the time the shutter was open. A fast shutter will "freeze" each moment in time clearly, but also lowers light sensitivity, so best used outdoors in good light.
It can be fun to play with shutter speeds - on my honeymoon, I was shooting the airplane prop out my window and cranked up the shutter speed until the prop STOPPED and I could read the serial number off of it in my viewfinder!! Note this was in the old days with CCD sensors - the new CMOS sensors have skew which warps the image in many cases.
Note that very high shutter speeds will result in choppy motion, so only use as needed.

Slow motion and frame rate and shutter speed

I have two cameras that record 60i and three that use 30p. Neither of the 60i cameras has a 30p option (one has a pf30). If I understand how FCPx handles this, if I drop both frame rates into a project, I get 30p out, correct? In effect de-interlacing the 60i footage to 30p. Is it best to import the 30p footage first to set that frame rate so that the 60i gets rendered to 30p?
We're producing a fishing DVD so good quality motion footage is important. This is an instructional DVD so I will be using some retiming to slow footage down to illustrate key points in the instruction.
I've read a lot of stuff on 1080i 60i vs. pf30 vs.30p vs. 24fps and benefits of using 720p vs. 1080i. Also looked at information on slow vs. fast shutter speeds.
So, the bottom line to get the best motion results for the DVD, I should be shooting at best bit rate possible, use 1080i 60i or 30p depending on the camera and let FCPx set everything to 30p. Correct?

For the 1080/60i media, it is best to have FCPX conform it to 30p (29.97p). [30p is a real timing: 30 exact frames per second, but it is not broadcast compliant. 29.97 is quite often simply referred to as 30, just for simplicity and/or laziness. The final decision for which to use rests with you. Also note, like "30 fps", 60 more often refers to 59.94 fps... for the same reasons.]
As for your target being DVD: DVD is always 480 lines whether it is anamorphic (16:9) or standard 4:3. If you would like to have "enhanced" slow motion, my recommendation would be to shoot in 720/60p (which is genuinely progressive "60" frames per second) and will give a slightly better edge on slow motion effects (retiming). That said, FCPX retiming is usually quite good no matter what the frame rate (frame blending recommended over optical flow [which tends to give a "morphing" effect when pushed too far].) 1280x720 frame size will give you plenty of downsampling resolution for DVD as well. [I *believe* that FCPX will use all of the 60fps available from the original video in retiming, even if the frame rate of the project is slower than the original media; so, 720/60p conformed to a 30p project and retimed to 50% will use every frame of the 60p slowed down by half... (somebody correct me if I'm wrong!)]
Best bitrate is also an important feature, but that is not due to the choice of format as much as that provided by the camera itself. Bitrates out of the camera may be relative to the frame size (they are in my consumer camcorders). A common consumer grade camcorder will top out at a bitrate (for 1080) somewhere between 17.5 and 22.5 Mbps, whereas an HD capable DSLR will usually top out at (easily) *twice* as much (45Mbps average from my Canon T4i) or more. Furthermore, the DVD standard imposes framerate restrictions (max is somewhere between 5 and 8Mbps -- the software that creates your DVDs will usually transcode for best bitrate, so not something you really need to bother with - just set the transcoder to best possible quality and provide it with the best quality video that's reasonable.) Whichever camera provides the highest bitrate should be your "main" camera.
As you may have discovered: another factor for a quality video regardless of camera is shutter speed. If you set the shutter speed too high (faster than twice the frame rate) then you will have "stuttering" issues (there will be "gaps" from still frame to still frame). Keep the shutter speed at the same or no more than twice the frame rate: e.g., for 1080/30p (target) the shutter speed should never be more than 1/60th of a second (I'll use 1/30th, 1/40th, or 1/50th usually). I haven't shot a lot of 720/60p, but I think I would still keep the shutter speed at between 1/60th and 1/120th exclusively [that is -- I wouldn't go as high as 1/120th or greater... but that's me... you should experiment for best results for you. If this creates exposure issues, then consider neutral density filters or circular polarizing filters to help bring scenes into exposure range (via aperture or iso or both.)

Good luck! Have a good shoot!

Working with slow motion/mixed frame rates

Hello!
Just wondering what the best solution is for slow motion. The majority of my footage is shot on DSLRs in 1080 at 29.97fps, so this is my sequence and project setting, however, I also have some slow motion clips shot in 1080 at 96fps. I have tried selecting the slow motion clips to Modify, Interpret Footage, Assume this frame rate but for some reason it's not slowing down in the playback and the metadata is still saying the clip is shot in 29.97fps. Am I forgetting something?
Thanks in advance!

Hi,
I have the same issue, I have tried with CS6 and CC same issue.
even with the sony plugin.
come on Adobe

How to best achieve slow motion and fast motion

Hi - I am new to the forum and a basic user of Premiere Pro CS5. I am working on a project shot at 24 fps, and would like to do slow and fast motion.
From what i understand there are 2-3 different ways to do this in Premiere - choosing speed/duration of the clip from timeline, or choosing time remapping form effects panel ot using rate stretch tool. Wondering how do these compare and which is better - any pointers for this will be great help. Also is slow motion and fast motion better done in After Effects than Premiere. Or any recommended plugins that would work on cs5 and cs5.5. Thanks.

The main difference between using time-remapping and just using time-stretching is that time-remapping allows you to change the speed quite flexibly at different times in the same clip, whereas stretching just changes the rate for the whole clip.
See this page:
"Change speed and duration for one or more clips"
> Also is slow motion and fast motion better done in After Effects than Premiere.
After Effects has far more control, especially with regard to how new image information is created between the original frames when you change speed and require frame interpolation (frame blending). Pixel Motion and Timewarp use a very advanced motion vector method (based on the Foundry's Kronos software) for doing this.
See "Time-stretching and time-remapping".

Slow motion and speedup during a single clip

Is there a way to take a single clip, and slow down portions of the clip, while speeding up other portions of the clip.
Is there a way to adjust playback speed using keyframes I guess is my basic question, so the start of the clip is slow motion, then the middle is played back at an accelerated or normal rate, then the end of the clip becomes slow motion again.
-Roger

Yes, is the short answer. Using the time remapping feature in the "effects" panel (top center of the screen, second tab from the left) you can set certain portions of the clip to play back at normal speed, then slow it down in certain sections, and then speed it back up. You can also cut the clip using the razor tool (in the tools panel at bottom right of the screen) and just reduce the speed of that section of the clip. The downside to using the time remapping (if my memory serves me - don't take my word for it) is that you lose audio, but the transitions from normal to slow-mo and back are much smoother. Using the razor tool, you simply place the timeline indicator where you would like to begin the slow motion segment, then cut the clip with the razor tool, the repeat the process where you want the slow-mo section to end. Then, select the section that you want to play back in slow motion, and reduce the speed. This is the method that was used before the time remapping feature was available. The transitions are not at smooth, but you can keep audio for the sections where the speed isn't modified. Just be sure to select the "ripple edit" check box when you modify the speed/duration setting of the clip (right click the video clip to get the speed/duration setting dialog box).

Slow motion and other effects are grayed out

Just switched from iMovie 9 to 11, and can't take advantage of the slow motion, instant replay and other effects, because they are all grayed out in the Clip menu. Why? I do not see the "convert entire clip" option referred to in the help file. What is wrong?

Yes, that is it. The trailers are pretty scripted.
If you want to add an effect to a trailer, first complete the trailer.
Then, in the Project Library List view, right click on the trailer name, and select DUPLICATE. (This will give you a copy of the trailer in case you want to edit it some more.)
Then, with the trailer name still selected, click FILE/CONVERT TO PROJECT.
This will turn your trailer into a normal project, and you can use any of the capabilities of iMovie, including the slow motion and instant replay effects.

Slow motion and Normal speed?

Can I take video shot 720p at 60 fps and use both slow motion and normal speeds in the same video??

Time Stretch is where I would start. If you need to apply that Effect to only part of a Clip, just use the Razor/Scissors Tool, to Cut that Clip, into the segments, where you wish to apply Time Stretch.
Posterize Time can be effective, as well, but from my reading of your needs, I think that Time Stretch (Rt-click the Clip, or Clip segment and apply).
Good luck,
Hunt

Slow motion and reminder setting

Guys,
Is there a function for slow motion and for setting a reminder for a program rather than recording?

JMF Dimension and frame rate

Why I'm not getting success when I try to determinate the Dimension and frame rate of the VideoFormat passing the parameters to the constructor ?
processor.setContentDescriptor(new FileTypeDescriptor(FileTypeDescriptor.MSVIDEO));
TrackControl tracks[] = processor.getTrackControls();
float rate = Math.abs(Float.parseFloat(jcbQuadrosSegundo.getSelectedItem().toString()));
VideoFormat vf = new VideoFormat(VideoFormat.H263, getTamanho(), Format.NOT_SPECIFIED, Format.byteArray, rate);
FormatControl fc = (FormatControl) tracks[0];
Format f = fc.setFormat(vf);
tracks[0].setEnabled(false);
processor.realize();
...getTamanho() return an Dimension that indicates de width and height.
jcbQuadrosSegundo is an JComboBox.
Thanks !!

Skype is generally on autopilot. I believe 1920x1080 (1080p) would be the max resolution as far as I can recall. If the Internet connection isn't good enough at both ends, it will drop down to the resolution the call can handle. The max resolution of the mobile device would be dependent on the hardware and the Skype client. The webcam resolution compatibility is sometimes dependent on the version Skype. Some people achieve better compatibility with the desktop version 6.1 vs the current 6.3. If you want to monitor the resolution you can view the call technical info. It will display the current resolution of both feeds and other call stats.
This external site has some good info on it, though a bit dated, it should provide some insight. I'm not sure if any of the mobile resolutions have been updated greater than 320x240.

What do the "Automatic" settings do for Frame size and Frame rate in Compressor 4.1.1?

Can anyone tell me, very specifically and with technical detail, what the "Automatic" settings do (in Compressor 4.1.1) for the following setting attributes: (1) Frame size and (2) Frame rate
Thank you!

Hi, in addition to Russ's advice for the VIDEO PROPERTIES in the Inspector, you might consider the "automatic" options being proposed by compressor.app V4.1.x as OPTIMAL for the destination codec you have specified that deviate (or differ in some way) form the MASTER (source) from where your are transcoding. There's no real TECHNICAL detail. These UI values simply are passed as parameters to the codec. The image/audio results can be PREVIEWed ofcourse in the compressor.app V4.1.x UI (Current PAne) ... us the slider and the timeline to determine final taste!
Suggested Examples may include:
REDUCED frame rate for a slower device or stream or bit rate or destination dleivery platform
reduced bit rate for older devices
smaller FRAME SIZE for say SD devices specified
INCREASED frame size with added "padding" in a situation like LETTERBOXING (4:3 in a 17:9 for example.. may others)
ye old PAL to NTSC conversion
inter-frame group of pictures (GOP) for distribution.
Scaling
retiming
cropping verses scaling
or simply what compressor.app "thinks" would work best - usually the best for most work.
others will have many more suggestions.
Also note that there are some nice overidding settings in the inspector/Video for resizing and retiming and Cropping you might consider.
For client based production distributions, many of us use CUSTOMISED settings. You may create and delete these on an AS NEEDED basis.
Lastly, There's likely a good write up the defaults in the latest Compressor.app V4.1 Users Guide PDf - you might want to pull it down from http://manuals.apple.com and shove it in ibooks.app. I recommend getting a copy. Also get the latest FCPX 10.1 Users Guide and Motion while you're there. Great for iPAD and iPHONE too if you get bored.
FWIW.

Slow motion and time measurement

Hi I have a problem and im wondering can someone here help me with it. Im trying to measure time in my .mov file. I wish to slow down the movie and measure time in the movie. Is there anyway of doing this. Im hoping to measure it quite accurately

Hi -
The short answer is yes, this is possible by using iMovie, Final Cut Express or Final Cut Pro to slow the movie down.
The problem is the precision of the time intervals displayed will be based on the original frame rate of the video - slowing the video down does not add temporal resolution, on the other hand, it demonstrates the relatively low temporal resolution of video at nominal rates of 30 fps - effectively 30 samples per second.
The only method you have of counting time between the start point of the action and the end point of the action is to count the frames that occur between those two points and divide them by the frame rate used to shoot the video. This might be easier to do with the movie running in slow motion, but it will not increase the accuracy - you just see the frames go by, each frame individually held for display in longer intervals.
There are high-speed cameras that shoot at 1000 fps available for rental which when you slowed down will allow you much greater precision in seeing action unfold in slow motion - but the rental charges can be staggering:

Hope this helps.

Slow Motion and iDVD

I have looked through various questions and answers for months now and have never been able to sort out the fact that iDVD won't create watchable DVDs of my .mov files if they contain slow motion. I'm using iDVD6.
I used to do this all the time on my old G4 iBook without any problems, but the encoding on that seems to have been updated as well.
It's infuriating to be able to watch a nice smooth movie in Quicktime at full resolution, then have iDVD create a rubbish DVD version with flickering and juddering. I video sports activity and use slow motion a lot.
I've tried switching between Best Performance and Quality, have tried creating a disk image first then burning slowly.
So many people seem to have huge frustrations trying to do simple things with iDVD. I have been a Mac fan for years, but my DVD problems and the swathe of DVD problems experienced by others has really tarnished my view of Apple. There is clearly a problem with the way iDVD encodes video, so where's the fix?
Should I just give up and use Toast? Any warnings about that?

Welcome to the forums.
Here are a couple ideas: If your video is under 60 min, use Best Performance for the highest resolution. Import your video from the iMovie file rather than exporting or converting the file (use the Import command or drag the file into your menu area).
Please advise where the .mov files originate; Quicktime is a container format and your .mov file can be more or less compressed... and break down during slow motion if it's substantially compressed or has a low frame rate.

Slow motion and trailing in premiere pro cs6

attached is a sample of a clip edited years ago with liquid edition.
In liquid edition "timewarp editor" you could create slow motion together with trailing effect as it shows in the attached clip.
I wonder if it can be done in premiere pro cs6
thanks arikw

Well, you could do it manually if you wanted to. Just pile up a few tracks of the same clip and offset each one by a frame or two from the others. Then set the opacity to something low, like 25%, and see how that looks.
There may be an effect for it that I just am not familiar with.

Motion 5 Frame Rate Dropping

So I'm using motion 5.0.7 on my 2010 MacBook Pro with 8GB of RAM and no other applications open and when I play video footage at 1080p at 25fps in the playback window, even if I have done nothing in the way of editing it, the frame rate drops to 7fps and lower. This is particularly frustrating as the video tends to 'jutter' when playing back?
Any solutions?

Well, laptops don't have the most powerful GPUs in them, which is an issue for Motion. What is the duration of this project?
Go to the Render menu (top right in Canvas) and make sure you turn off all functions you don't need (lights, shadows, etc) and drop the quality and resolution settings a bit lower.
