If I "modify" a clips frame rate is this a permanent alteration, as in Apple Cinema Tool?

I have some footage shot at 59.97 FPS and need to interpret the frame rate at 23.98. If I do this via the "modify, interpret footage" menu options, will this permanently alter the clip? In Apple Cinema Tools, it permanently alters the footage.
Thanks!

Clip frame rate wrong in imovie 11

Ever since I upgraded to imovie 11 all of my video clips show a 60 in a yellow frame - both in events and projects - with the message "indicates clip frame rate (60fps) is not a multiple of the current project (25 fps)". What does this mean? As I said shows in events and projects. To stop audio jumping I detached all audio from clip but how do I fix the clip frame rate? Assume this causes "jumpy replay" problems. How do I fix and where??? Please help. Could not find solutions anywhere.

Are you speaking about this particular change of frame rates or any?
Having transfered Super 8 film that was shot at 18 fps, I have little choice but to change the rate. So far everything seems to be working out fine. For 24 fps iMovie does a pull-down of 1 1 2; for 30, 2 2 1. I'm a little confused as to whether I should use 24 or 30 fps. I'll be asking about this in a new thread.
The easiest way to change a projects framerate is to edit the project xml file.
Right click on your iMovie project file and choose "Show package contents..." (or something similar)
Edit the "Project" file (no extension) using the free Textwrangler editor or a plist capable editor.
Find the node "frameRate" and update to 30.
Really? That's a cool trick! But it sounds like it could easily mess things up. Have you tried this and with what scenarios?
or easier just create a new project

So close to fixing this problem with iMovie clip frame rate!

Hi! Please help!
I'm recording short videos in iMovie using the built-in camera on my Macbook Pro. I did this yesterday and again this morning without incident. Everything worked great. Then, this afternoon, I made another video - EXACTLY the same way I'd done the other ones - and yet, this time, the clip mysteriously recorded at 18fps instead of 30fps. As a result (I think) the audio is out of synch. I have detached the audio as some have suggested in other forums, but this has not fixed the problem.
QUESTION: How can I convert the clip from 18fps to 30fps?? Is this even possible?? I'd really like to avoid re-recording, if at all possible.
I am a novice. Please explain any solutions to me as though I am a child. Thank-you!

Duplicate frames in clip. frame rate?

I was scrubbing through some footage in a clip in my viewer window. I noticed something interesting. As I was scrubbing, I noticed there were a few duplicate frames.
E.g.: A B C D D E F G H H I J K, etc.. etc..
so 3 unique frames, 2 duplicate frames
what does this mean?

Sounds like a normal standards conversion or film transfer pulldown, or media that has been slightly slow-mo'd for some reason. Usually when people have this they know why it's there.
The particular way you're seeing it probably also has something to do with your viewer being set to less than 100%, so you aren't seeing both fields (you would also see them on a native format external CRT).
But you don't say anything about what this media is, where it came from, what your clip settings are...

Frame Rate - Is this info correct?

If I have a 25 fps movie and I want to make an SD NTSC dvd I can drop it into encore and it will convert it to 29.97 so it will play in a region 1 dvd player automatically. However if I want to make a NTSC blue ray then I will need to have a region free blue ray player in order to play it because it will keep it at 25 unless I take it into another program to convert it to 24 or 29.97. Is all is this info correct? Thank you

Help with sequence settings in final cut for project with 2 different frame rates.

I really need help with this one! I finished editing a wedding video and realized after exporting that it was filmed in two different frame rates. This has happened before but I converted the footage to match and fixed the problem. In this case, the footage is part 30fps and part 60fps. The majority of it was filmed in 30fps. I cannot convert the 60 to 30 without the slow motion effect which I do not need so I have to find a way to burn this to a DVD without it looking messed up! The video was shot with two Canon 7ds if that helps anything. The first sequence I set at 29.97 and exported as a quicktime movie and all the footage filmed in 60 looked perfect and the footage in 30 looked jittery. Then I tried the sequence at 59.97 and it switched. The footage filmed at 30 looked good and the 60 was cropped in. I am so confused! Any advice or suggestions would be greatly appreciated!!

Thanks for your help Michael! The frame rates are 29.97 1920 x 1080 and 59.94 1280 x 720. I did a control click on the clips in final cut and viewed the item properties/format to find this info. The Canon 7d is a DSLR but we use it for video. As for my workflow, the first thing I do is import the footage onto my computer and then drag the clips into mpeg streamclip. I choose apple prores 422 and uncheck the interlaced box. Once this is done I import the .mov files into final cut. The sequence automatically sets itself to whatever clip I drag in first so it originally set as 29.97. When I finished editing wedding video, I export it to a quicktime movie and choose whatever settings match the sequence, in this case apple prores 422 1920 x 1080 30p. Once that is done I use iDVD to burn the discs.
I knew something was wrong when I watched the quicktime movie and all the 30fps footage was jittery and most of the cross dissolves looked strange. That's when I figured out the footage was at two different frame rates. What I don't understand is why whatever the sequence is set at in final cut, the clips of the opposite frame rate look right but the clips set at the matching frame rate don't???

Progressive frame rate

This is my first foray into HD, so my apology for this rudimentary question.
How can I tell if an HD footage is progressive or interlaced?
I have 30min worth of HDCAM. The post house that did the transfer told me that they're 1080p25 (I have no reason to doubt them). I'm just curious if there's any way I can double-check to make sure that they're 25p and not 25i.
I imported a sample clip into FCP and looked under 'Item Properties'. I only saw the following data but no mentioning of whether it's progressive or interlaced:
Vid Rate: 25fps
Frame Size: 1920 x 1080
Compressor: Uncompressed 8-bit 4:2:2
Pixel Aspect: Square
Field Dominance: Upper (Odd)
By the way, does progressive video have a field dominance?
Thanks,
td

Thanks for the detailed answer. I'm based in Vietnam and none of the local post houses have much experience in doing progressive HD since most of their work is for TVCs. I had to go to Bangkok to do the full-grade transfer (from 35mm) to HDCAM and conform in FCP. I specifically asked for 25P frame rate because this will finish in film. I wonder if they messed up (I hope that's not the case).
I just need to clarify a few things.
The reason my question came up was because as I understand it, progressive video should have no field dominance. Is this correct?
All these footages have Upper field dominance. Is this a definite indication that they're interlaced? Are there any type of HD that has an Upper field dominance?
I did a few test and got mixed result. But I'm not sure if this is because my system is not set up to do anything more than DV, and I don't have a 1080p25 Codec in my system. These are the tests I did:
Since the post house has a more recent version of FCP than I do, they gave me an XML file of the conformed project. I imported the XML, with the 'Override with setting from XML' box checked. Everything is red on the timeline, even after I changed all the timeline's settings to match the footages' settings.
However, when I create a new project, set the Sequence Settings to 1920x1080, Square pixel, Upper Field Dominance, Compressor as Uncompressed 8-bit 4:2:2. Import a clip directly into the FCP project and place it on this time line. It's gray.
I created a new timeline with same setting, except for Field Dominance set to NONE, the clip is still gray when placed on the timeline.
On the other hand, when I looked at one of the footages at full-size, frame by frame, on my Cinema display (I don't have an HD broadcast monitor), the edges look pretty sharp. For ex. I have a shot of a swish pan following a car speeding across the screen. There are some horizontal streaks in the background, but these look like motion blurs rather than interlaced artifacts. The edge of the car is sharp, with no jaggy. This seems to indicate that it's progressive.
My big worry is that the post house did the transfer (to tape) at 25P, but captured at 50i or 25i by mistake. Then again, if the Codec on the footages says Uncompressed 8-bit, then the captured footages should be the same as what's on the master tape, shouldn't it?
I'm thoroughly confused at this point. Anything that helps to shed light on this would be greatly appreciated.
I apologize for the lengthy note, but I figured it may help to give some backgrounds on the project. I need to get this sorted out before going online. This could be a very costly fix, especially since I'm paying for this film out of my own pocket. But at least if I catch it on time, I can minimize the damage.
Thanks again.

Variable Frame Rate on H.264 output

I am using AE CS6 (cloud version). I am trying to render compositions to 1080p mp4. Each time the comp appears to render fine. But bringing it into my NLE crashes my NLE. I brought the media into MediaInfo (app from SourceForge that shows everything about a media clip). It says that the Frame Rate is VARIABLE Min: 60fps; Max 60.6 fps. The composition was 80 fps, and I told the renderer to keep it at 80. MediaInfo also said the duration was over 6 seconds. The composition was a little over 4 seconds. So the overall speed of the comp was incorrect. I've been in the video business for about 10 years. I understand frame rates, etc. Never heard of VARIABLE frame rates until this.
I was able to launder the media file through a freeware media format converter, and got it back into constant frame rate so I could proceed in the NLE with the project. But the time was still 6 seconds. So I had to speed up the clip in the NLE to get it back correct.
Since moving to CS6 from CS4, I decided to start using the H.264 output module. So I've just started encountering this variable frame rate problem.
So my questions... What is variable frame rate, how did I 'request' it, why is even the variable frame rate no where near the comp frame rate, and what do I do to simply get an mp4 with the 80fps that I want?
This is very reproducible for me. My comps are usually either HDTV 1920x1080 or HDV 1440x1080.
Add to Render Queue
Select DV Settings, change field order to none
Select H.264 output module
Render
Can someone explain what's going on?
Thanks.
Jerry

Where did you get that footage and what format was it originally shot in? Was it shot in slow motion or did you change the frame rate in AE? Why would you need 80fps footage unless you're going to slow it down to a normal frame rate?
Also, h.264 is not only a very lossy format, it's also a bad intermediate format. So if you're planning on editting that footage later on in an NLE, I'd suggest rendering it to something else. Premiere should work fine with h.264, but not FCP, although I think they fixed it in FCPX, but you didn't say what NLE you're using.
Second of all, the H.264 encoder is much better in Adobe Media Encoder. Check this post by Andrew Yoole:

Report
As the other guys have said, don't use AE to render using temporal codecs. Temporal codecs like H264 rely on storing partial frames based on earlier information. AE renders and encodes one frame at a time, so most of the efficiency of a codec like H264 is lost. The result is that you get much lower overall quality from an AE h.264 render than if you were to encode it externally.
Adobe Media Encoder or Quicktime 7 will encode great quality H.264 files.
Was this helpful? Yes No
As I said I'm not sure why you would need to take an 80fps piece of footage back into an NLE, but if you're trying to make that footage play back in slow motion, you're going to have to re-interpret the frame rate of the footage in After Effects to play back at standard rate. And, if you're going to use the AE Render Queue to output something for more editing, I would suggest using best settings and outputting to a production codec such as a ProRes, Animation, Uncompressed 10bit, Uncompressed 8bit or Black Magic.
Also I've never used that media info app before, but I know that when you open up quicktime and hit command I on the mac to view the inspector, the playing fps jumps around. I think this happens because the player doesn't necessarily play back the correct frame rate at all times.
This Adobe Captivate blog talks about variable frame rates in F4V files. Maybe it might help explain things.

FCE frame rate problem?!

Hi, if someone could help me with this asap that would be so helpful?!
Basically I'm having a problem with the frame rate in Final Cut Express. I was using 3 different Sequences to edit different clips/audio in. I then wanted to put them all in to the same Sequence but when I did the clips were flashing different colours and wouldn't play properly. All of the clips were 30fps however the project frame rate was 29.97fps? How did the frame rate of the project change because I didn't know you could change it and how can I change it back?! Thansk :-)

29.97fps is the actual frame rate for NTSC (North American) video. It has historically been called "30fps" for convenience sake. However in recent years true 30fps capability has appeared even in some consumer camcorders. This can result in some subtle problems if you mix real 30fps material in a standard 29.97fps sequence. The "change" you refer to could occur if your clips were recorded at a real 30fps and you put them in a 29.97fps sequence. FCE will try to conform the clips to the sequence settings.
For completeness, here is what FCE supports:
SD video at the following frame rates. FCE imports DV video as QuickTime/Apple DV during capture from your camcorder
DV-NTSC @ 29.97 fps
DV-PAL @ 25 fps
HD video at the following frame rates. FCE transcodes all HD video (HDV and AVCHD) to QuickTime/Apple Intermediate Codec during capture from your camcorder.
720p25,
720p30
1080i50
1080i60

Why did frame rate of video shot on iphone 5 change from 30 fps to 24 fps?

Why did frame rate of video shot on iphone 5 change from 30 fps to 24 fps?

My understanding (which could be wrong) is that the iPhone shoots video with a variable frame rate. This is likely so it can optimize video for FaceTime. So uncomplicated scenes can be shot with a lower framerate, and active scenes will be shot with a higher framerate.

Frame rate = One picture in 5 seconds?

Hi, I am capturing video from a web cam in rgb. I want to send only one picture in five seconds across the network (Frame Rate = 0,2). This does not seem to work. My code:
          Object frameRate = processor.getControl("javax.media.control.FrameRateControl");
          if(frameRate != null)
Logger.getInstanceOf().writeLog(Constants.LOG_INFO, this.getClass(), "createProcessor()", "Current frame rate is: " + String.valueOf(((FrameRateControl) frameRate).getFrameRate()) + " frames per second ...");
          FrameRateControl frc = (FrameRateControl) frameRate;
          frc.setFrameRate(0.2f);
Logger.getInstanceOf().writeLog(Constants.LOG_INFO, this.getClass(), "createProcessor()", "New frame rate is: " + String.valueOf(((FrameRateControl) frameRate).getFrameRate())+ " frames per second ...");
It seems as if I can only reduce the Frame Rate to 5. I am using a H263 video format. Does anybody know how to further reduce the frame rate?
Regards, Nik

Hi, I found the answer myself.
When you capture with RGB in Frame Rate 15 and 320x240 Dimensions and you want to transmit using H263, you can only reduce the Frame Rate to 5 FPS. I do this using the code above on a realized player. When you want to further reduce the frame rate you need to create a second processor taking the H263 Stream with 5 FPS as input. Using the code above on the second realized processor enables you to further reduce the Frame Rate.
This worked for me.
I also used the following code WITH NO SUCCESS:
     Format checkForVideoSizes(Format original, Format supported) {
          int width, height;
          Dimension size = ((VideoFormat) original).getSize();
          Format jpegFmt = new Format(VideoFormat.JPEG_RTP);
          Format h263Fmt = new Format(VideoFormat.H263_RTP);
          return (new VideoFormat(VideoFormat.H263_RTP, new Dimension(width, height),
                    Format.NOT_SPECIFIED, null, Format.NOT_SPECIFIED))
                    .intersects(supported);
Anyway ... the problem is solved.

Best frame rates for 4 different cameras in multicam

Well, I've been flopping around in different threads on this forum, but I think the question is beginning to finally take shape for me. Basically it's all about deciding on frame rates for four different cameras I will be using to shoot a 6-day intensive course I will be teaching. The video will be primarily for computer viewing (YouTube, Quicktime movies). Here are the cameras:
2 new Canon cameras capable of frame rates of 60i, 30 frames per second progressive "recorded as 60i", and 24 frames per second progressive also "recorded as 60i" (there is a known issue with importing the 30 frames per second into fcpx, as fcpx does not recognize this as progressive, but ClipWrap can get around this).
1 Sony capable of 60i, 60P, and 24P
1 Sanyo capable of 60i and 30P
Possible settings:
Just do all at 60i, but people say this is not so good for computer viewing
Canon at 30 fps (using ClipWrap to see it gets recognized as progressive), and the Sony and Sanyo at 60i. Will this cause syncing or other problems, mixing frame rates like this? How bad a hit in quality is 60i on computer screens?
Canon and Sanyo at 30 fps, Sony at 60i
Same as #3, but use JES Deinterlacer to get Sony 60i to 30 fps.(I tried this out, by the way, and the resulting frame rate, after deinterlacing, showed up in the inspector window at 30, not 29.97. Is that a problem?
Anyway, I aplogogize for wearing out my welcome on this forum, and I thank everyone for creating such a wonderful bank of information.

Not sure what you're trying to achieve here - for the best overall quality, if possible, choose a frame rate that all the cameras can achieve. That way you won't lose quality in the conversion.
If you're not satisfied with that, you need to do some tests to see which gives you the effect you like best. Nobody here can help you really - it's up to you.

What is frame rate with 1920x1080/60p?

I'm currently shooting and editing HD 1920x1080/60i (interlaced format, 29.97 frames/sec). To reduce motion artifacts, I'm considering a change in my workflow to HD 1920x1080/60p (progressive format), but first I must update my understanding of this newer format. Question 1: What is the frame rate for this format, 30 or 60 frames/sec? If the answer is 30 frames/sec, why is it called 60p? Question 2: How many complete scans (combining odd and even lines) are produced per frame? Question 3: Would a Master File exported from Final Cut Pro X (by default, a QuickTime movie file) be progressive or interlaced? Question 4: Would iDVD v.08 accept a progressive movie file for making standard DVDs?
Your answers to these questions are very much appreciated.

Thank you, Tom Wolsky and Karsten Schlüter, for your fast replies!
Tom, regarding my Question 4: Are you sure that the latest version of iDVD can accept progressive 1920x1080 QuickTime movie files at 59.94 frames/sec? As you may know, iDVD is no longer supported by Apple, and their Technical Support is unable to answer my question. I respect your experience in this area and would like you to advise me in my proposed switch to a progressive workflow. I can't afford to shoot in a format that will not allow me to make standard DVDs.
Best regards from Interlacer.

Mixing frame rates

Hi all. I will be doing a 3 or 4 camera project soon. I have two Canon tapeless AVCHD cameras, a Vixia HFM43 and an HFG10. I'm going to borrow two more cameras but don't know what kind they are yet. I was thinking of shooting the HFM43 in Canon's FXP mode with a 30 frame rate, and the HFG10 also in FXP mode but with a true 24 fps progressive, a frame rate that the other Canon is not capable of. I wanted the better frame rate because I am sometimes going to crop and zoom in on parts of the video taken with that camera, and the higher quality video it takes seems to make this possible without making the video too grainy. I have since googled a bit on mixing frame rates like this in one project, and people generally warn against it. Is this true? Is it better to stick to one frame rate?

Calm down, calm down . . . everything is OK.
Canon's 60i and 30p are both the same frame rate . . . 30fps. (Ignore the 29.97 as it is the daft American system and can be regarded as 30fps)
It's just that the 60i has 2 interlaced fields (don't worry about it!) per frame whereas 30p has 2 identical fields (equivalent to one field) per frame.
If you are interested you can read about interlaced and progressive frames in Wikipedia!
Suffice it to reiterate, they are both 30fps.
It would make sense in future to have all cameras set to the same although it shouldn't make any difference.
NOTE: Over the past few years a number of cameras have included a "60p" setting (note the "p").
This is 60fps and shouldn't be mixed with 60i or 30p

Setting jmf bit rate/ frame rate

Hi!!
I'm with some problems configuring my video settings.
Where should I go to set the frame rate od my video streaming?
I'm using H263 format, and the frame rate is variable and I want to set it for a lower value so that my video streaming can be more "fluid".
Should I go to Control Panel of the Windows and change there at Multimedia codecs?
Regards from Portugal

Here You have sample how to specify frame rate (in this exampke - 10f). I use here data from video caprure and create processor with ProcessorModel. Then I send it by network (RAW_RTP - in this dimentions it id H263)
VideoFormat vf = null;
Dimension size = new Dimension(176, 144);
vf = new VideoFormat("RGB", size, Format.NOT_SPECIFIED, null, 10f);
Format [] formats = new Format[] { vf };
ContentDescriptor cd = new ContentDescriptor(ContentDescriptor.RAW_RTP);
ProcessorModel proc_mod = new ProcessorModel(dsCapt, formats, cd);
dsCapt is DataSource from my capture device.
for details look: JVidCap file from : http://java.sun.com/products/java-media/jmf/2.1.1/solutions/JVidCap.html

If I "modify" a clips frame rate is this a permanent alteration, as in Apple Cinema Tool?
