Different frame rates in one movie

Hi there... have a flash movie at 18 frames p/s, have had to
embed video which is at 25 frames p/s (obviously this means that
the video itself is slower than the sound). Is there any way i can
use action script to control the frame rate of a movie - have it at
18 fps for a certain amount of frames, then up to 25 fps for the
next couple of frames, and then back down to 18fps??
Any help would b greatly appreciated.

Import with progressive steaming and it will not matter, and
you shouldn't embed FLV files unless it is absolutely necessary.
You can't change the frame rate with actionscript.

How can I edit multiple clips with different frame rates on the same timeline

how can I edit multiple clips with different frame rates on the same timeline

You do not want to edit material from different frame rates on one timeline. You CAN do this, but it is a very bad idea - and this is why.
Once you establish the sequence frame rate - lets say it is PAL material at 25fps, any material that you drop into the sequence other than 25 fps will have to be changed to play at 25 fps. If the material you add is NTSC (29.97), FCP will DROP 5 frames per sec to bring the frame rate down to 25 fps. Which 5 get thrown away? Every 6th one. This yields a funky cadence that becomes even more complex as as there are also interlaced fields (DV/NTSC is an interlaced format). Oh, and by the way, the image sizes are different as well. DV/PAL has 576 lines of resolution and DV/NTSC has 480. FCP has to scale up the NTSC to fit the PAL frame.
You do not want FCP adjusting these things on the fly. You want to do a thoughtful (and time consuming) conversion so that you end up with all your material in one format with the best possible image from the conversion process. Compressor can do an adequate job with Frame Controls turned on. The Natress Standards Conversion FCP plugin is another way to go. A third option is to find a post house that can do the conversion for you using a hardware based process.
The good news is, once everything is in the same format, editing it will be painless and the output process very quick.
Whatever frame rate/ image size you select, I'd suggest using ProRes for the codec. It is 4:2:2 color and will withstand color correction and composting with much more grace than any variant of DV based codecs.
Have fun.

Different frame rate in movie mode? iPhone 4

I noticed that my iPhone shoots video clips with different frame rate from time to time. I suppose it slows frame rate on dark shots. For now all of my daylight shots are 30 fps, while night or dark ones are 25 and 24. This makes it hard to edit clips in iMovie for example, because difference in frame rate causes strobe motion effect on output.

Anybody have the same?
For reliable results I would suggest to shoot two clips: one in sunny daylight conditions, another with ordinary room lightning, maybe a little darker than normal.
Please let me know of the results. Thanks

Doesn't seem to be just a Quicktime bug:

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???

How can I use two sequences w/ different frame rates

I shot wedding (on Sony Z5) initially (1st tape) in DV widescreen (29.97/ 30 fps) but tapes 2, 3 & 4 were shot 1080p24 fps Big mistake; now obvious.
Edited all in FCP 6. On trying to cut & paste sequences together I get " cannot nest sequences with different editing timebases".
I have 23 min.intro/ ceremony sequence as stand alone QT mov now. How can I best convert that and/or merge it w/ the rest ( 62 min. 24 fps sequences), or perform other action to unite the diff frame rates into one, w/ best looking quality for the DVD/ bride & groom? Trying to beat Xmas deadline...
Thanks in advance! Happy Holidays to all.
3 Ghz Intel Core 2 Duo / 8 GB / OS 10.6.8 FCP 6.0.6

I went back and forth on this.
Ordinarily, I'd conform to the format that the majority of the footage was shot in. But if you're going to DVD, and it's going to be compressed to 480 anyway, then why not down convert the 1080 footage to 480?. At the same time, I would imagine re-timing the 24 (23.98?) to 29.97 would look reasonably consistent with the 29.97 SD.
This could be done in FCP, but I think Compressor will produce a better result. The adjustments you need are in the Settings menu in the Encoder (with Audio set to pass through), Geometry (720x480 16:9 Anamorphic), and Frame Controls (Resize Filter set to Best).
This will not be a short encode, so I would first test a short section to double check your settings and sound sync are right, and to compare against the quality of tape 1.
Good luck.

Concerning multiple frame-rates in one export file to perceive important necessary philosophies.

consider READ QUESTION, The following 4#'d Paragraphs should be skipped and not considered to be read and don't link
to my discussion it's question.
4.It's a strange world we live in, yet the wonders are revealed if realised once more.
Hello my dear friend or opposition. As this was my first post I represented my normal
thought flow throughout as it would be me daily, reflecting as necessary, apologizing in advance
if thrown out of balance.
1.Rather contradicing or raising questions, I would like to consider this very moment the age
of turn around points. As the evolution and perhaps one a day, revolution continues I would
like to take a moment to stand by this process, I conclude we are going towards the red pitt hole.
2. I also consider After Effect a program to allow whatever creativity could thrown at it, powered
by our imagination creating a new breed of cinema. I consider myself a philospher, always spellinG it
wrong but even thaT I consider mental restrictions only preventing me to reach out for your location,
wherever or however you may consider that to be so.
3. Proclaiming filters most out, but if I could only change one mind, I succeeded. I plan to rewrite
or so to speak, re-introduce what could be film and where we could are going with it, possibly. Film will
be an art that could differ as much as some painters have created unpredictably impossible differences
between them selfs. Concludingly art style differ so does reality, I am thanking the creators of After Effects,
and improvers, hereby with a salute for a program potentially as versatile.
QUESTION
Film=60:00 seconds
first 00:10 seconds=>a 2000FRAMES/s animation,
2nd 00:11-60:00 seconds=> 60FRAMES/s film.
Exports results in one frame-rate, I have done insufficient research as why this is still a limit,
or might not be because of simply not knowing enough yet. I created this story that could
potentially explain our source and the infinite continuation of that and why.
Thank you for your time, and I do appreciate it already if
you read this far. Information regarding the question is fine.

Imagine a movie theater. The projector is running happily away at 24 fps. All of a sudden you want to watch the movie at 60fps. You pick up your cell phone and call the lobby and talk to the manager. He thinks this is an interesting idea so he sends the projectionist up to the booth to look for a speed control on the projector. No luck, this one only runs at 24fps.
That's how video containers work. You render to a container (mov, avi, flv, whatever) and you've just bought a projector with only one speed. If you want to change speeds in the middle you have to have a very special projector. No way around that.
So the answer is that you can't render to the same container with different frame rates.
You can, however, in a single comp, have footage that runs from 1 frame per hour to 99 frames per second. You can interpret the footage placed in a comp at any frame rate from 1 per second to 99 frames per second, which would accomplish what you are trying to do, except for the part that the first hour of the movie rendered movie would contain more than one frame.
There are different types of containers however that can display each frame for a specific time interval. Animated Gif is the simplest movie container of this type. Flash is the most common. These are non standard video containers and you have to control the timing outside of AE.
It would help if we had a little less escortaric posing of your question. What exactly, in an actionable question, are you trying to do and why?

Re-connecting media to different frame rate clip

Hi guys,
Wondering whether anyone can help me out to solve an error I've made...
So, I've basically completed an edit (some episodes on Final Cut Pro X, some on Final Cut 7) only to find out that I'd transcoded the media at the incorrect frame rate, 23.98 instead of 25fps. Yup, pretty big error. And now I need to redeliver the projects in the 25fps format.
I've transcoded a clip to the correct 25fps rate and tried to reconnect that clip to the 23.98fps one in the timeline, but I'm unable to reconnect as the clips are of differing frame rates.
Has anyone got any ideas how I can reconnect the clips or any suggestions that will make this situation easier to rectify rather than copying out the entire edit which will cause me to spend a week crying into my keyboard.
Thanks in advance for any suggestions.
Olly

Hmmm...
Tried this but it brings in the media that is 23.98 and there's no way I can tell to link to the new 25fps clips. Unless there's anything else I can do? Any other way to match the clips? (the 25fps clips are that little bit longer in duration) I also have some edits in fcp7. By using cinema tools in that would I be able to change the frame rates and link up to the new 25fps?
Cheers for the advice though Russ, this way does give me the template of the 23.98 edit so that I can match the new 25fps shots to, but it's gonna be a long process.

Relink project clips with different frame rate

Somehow the clips in my project sequence ended up with a different frame rate (25) than the original media files (23.95), and they are no longer linked -- maybe this happened during import from iMovie. When I try to relink project files to source media, I get an error message saying they cannot be relinked because they have a different frame rate. I changed the sequence framerate to 23.95 (by creating a new project with 23.95 as the frame rate, then copying and pasting the other timeline into it), but all the clips remain at 25, so the problem remains.
How can I change the clip properties to frame rate 23.95 so I can link to the original media?
Thanks.

The media got unlinked importing the project and events from iMovie to Final Cut.
I've attached screen shots with all the specs.

Two timecode stripes at different frame rates? (and other BITC stuff)

I'm not an FCP user, but I'm working with an editor who's not that up on the finer points of FCP operation. Would like to know if certain things are possible...
1a. Is it possible for FCP to simultaneously output a QT file with two different BITC stripes running at different frame rates (say, 29.97 fps and 23.976fps)? Or...
1b. For an already BITC'd work print (striped with 23.976 timecode) is it possible to add a second stripe at 29.97 fps, synchronized from the 1-hour mark (first frame of picture)?
2. Are there any parameters available in FCP to adjust the size of the numbers and the position of a timecode stripe?
3. BONUS QUESTION: what does the "R" in "TCR" mean? (just curious -- I've seen this for years but never knew what the "R" stood for).
Message was edited by: iSchwartz

iSchwarz!
Welcome to the visual side of things. Never thought I'd see you venture out of Soundtrack Pro and Logic land, glad to see you here.
3. R stand for Reader. TimeCodeReader. G will stand for Generator. TimeCodeGenerator
2. You mean adjust the TCR window? If you drop the filter on a clip, load that clip into the viewer, you can adjust the filter parameters there.
1b. BITC? There are 2 type of timecode that I'm aware of: VTC (or ViTC)(Vertical Interval Timecode) and LTC (Longitudinal Timecode). I seriously doubt this as then FCP would have to use to different timebases within the same sequence.
1a. Again, I seriously doubt this do to the different timebases.
You could print to tape this 23.976 fps sequence which FCP would add the pulldown resulting in 29.97 fps timecode and then import that. Or, maybe Compressor can add the pulldown and export a file wtih 29.97 fps timecode. Don't know, never needed to try that.
Good luck, report back with your findings.

Footage of different formats on one timeline; also different frame rates

I need to edit footage of different formats on one timeline. The end product will be compressed for the web so I do not need to be working in HD.
I have been using the timeline settings for DVCAM (720 x 480) Anamorphic.
I have broll footage shot and captured at 960 x 720 59.95 FPS DVCPRO HD 720p60
And Interview footage shoot in DV Cam -- 720 x 480 29.79 Dv/DVCPRO – NSTC
When I put the HD footage on the timeline and render it, it appears to be in fast-forward – as if I adjusted the speed of the clip. I am wondering if it is caused by the difference in frame rates and also what I can do about it.
Thanks!

The main bulk of your footage is DV and DVCAM, with some B-roll at DVCPRO HD, and you need to deliver HDCAM? Then you either need to have a dub facility use a Terranex to upconvert all the DV to DVCPRO HD, or you need to invest in a Kona 3 and use that to upconvert your footage to DVCPRO HD...and also use that to output to HDCAM.

Working with many different formats/codecs/frame rates within one Sequence.

Good Afternoon,
As an editor for an ad agency I am being tasked with cutting a demo reel together. Nothing too difficult.
The reel is to include video footage of past projects, going back a couple years or so. The footage that I will be given will undoubtably be in a variety of formats, codecs, frame sizes, frame rates, etc (all SD, though). Delivery is SD DVD.
My question is this:
What is the best way to set up my timeline for a barrage of clips with differing specs?
Do I encode all the media assets FIRST to conform to my Sequence Settings? Or do I just deal with the large amounts of timeline rendering as I work with different formats and codecs? Or do I....?
I am running FCP 5.1.4, so I don't have the Open Timeline feature going for me.
I appreciate any advice and tips you can offer!
Thanks!

Your final format is NTSC SD DVD, so you're going to have to go to 720x480 at some point. This is what I would upscale to. Make sure your "client" knows that the 320x240 wmv's may not look to good in the final production.
Personally I use MPEG Streamclip (an excellent FREE application that's part of many a pro's arsenal) for this kind of conversion and/or upscaling. It's not particularly intuitive (especially for upscaling) so read the manual.
You may need to get hold of Flip4Mac or Episode for the wmv conversions.
I would tend to convert to a lossless codec like Apple Uncompressed or Animation. You could try going to NTSC-DV but you're going to lose some quality initially and again when you do the final mpeg2 compression.
Experiment.

Multiple formats and frame rates in one sequence

i have material shot on many different cameras. it includes PAL and NTSC, HD and SD, 24, 25, 30, and 60 fps, ProRes, DCVProHD, DVCam, etc etc. the final product is going to HD in both NTSC 24fps and Pal 25fps, for NatGeo domestic and international.
the roughs are already done with this hodgepodge. my job is to clean up the audio (done), and send the video out in for color, titles, and graphics. i'm trying to get at least the frame rates to match at 24, much of it is already in 24 dvcprohd or prores, so i have been doing quicktime exports of the non-dvcprohd/prores video to prores, then conforming to 24p in cinema tools, then overlaying the clips in the sequence with a fit to fill edit. sync has not been a problem, miraculously, even though the speeds end up between 100 and 125 percent.
am i doing anything right, and if not, what's a preferable way to handle this mess? i tried media manager initially but nothing would relink, so i gave up and started doing the clips individually as stated above.
all i know for sure is that whatever i end up doing, they're not paying me nearly enough.
-m

Hi Shane - Thanks for getting back to me! I figured I'd have to compress it, but
my question is - how? Initially, I used MPEG Streamclip to import the 23.98 dvd footage in as a DV/DVC Pro QT at 100% Best Quality. I then imported those files into FCP. After getting your e-mail, I went to export the files into Compressor (from FCP), and I'm only given 5 setting choices under "QT." I'm not sure which one to select . . . Uncompressed 10 bit? Any ideas? Again, thanks so much!!!

Video doesn't slow when added to timeline of different frame rate

I'm having trouble understanding what's going on here. I have a video shot at 59.94 fps, and I add it to a sequence that is set at 29.97 fps. It plays back normally which makes sense if premiere is dropping frames by 1/2, but the drop frame indicator says that it isn't dropping frames. The clip also runs the same length. The interpret frame rate for the clip in the project window says 59.94 fps, so if it's added to a sequence that is set at 29.97 fps and it's NOT dropping frames, shouldn't it be slowed down?

OK cool thank you very much. So I've been doing some research to figure out the best way to edit this project. The problem is that I have some GoPro videos shot at 1080X1920 and 59.94 fps and some at 480X840 and 240 fps. But the catch is I want to make the final product work well for Youtube. This is how I feel I should go about getting the best quality for my final video.
1. Set the sequence settings to 720X1280 (which is what I will export as so that the 480X840 doesn't loose as much quality compared to having to resize up to 1080X1920 to match the other clips). I don't think there's much quality loss in down-scaling the 1080X1920 to 720X1280 (if any, or is there?), so it's kind of a happy medium for both frame sizes that I have and it's still good for Youtube.
2. Apparently Youtube really works well with 29.97 fps, so this is what I will set the sequence frame rate at.
**Another side question I have is what if my sequence frame rate is set at 29.97fps and I interpret the frame rate of a 59.94fps clip as 29.97fps and add it to the sequence. Now if I use the rate stretch tool to speed up the now slowed down clip to 200% so that it plays at normal speed. Will Premiere remove frames to speed up the clip or does it really increase the rate of the frames so that I don't loose any frames?** My guess is if I export at 29.97fps it will remove half of the frames.
Is it not possible to have an exported movie clip that contains multiple frame rates?

Inserting old swf into new fla with different frame rate

Hi, I'm trying to insert an old banner ad into a new Flash site. The problem is, the banner I made at 20 frames per second, and the Flash site is set to 41, so it literally plays the banner twice as fast. Any ideas as to what I can do about this? Thank you.

A few of them I may have the original source files on disk. Do you know what's the easiest way to transpose them to the higher frame rate?
For the ones I don't have, I should open the swf file in the new site and add a frame between each already existing frame?
Yes I imported the swf, I'm kind of just finding my way around Flash and I don't know how to load them dynamically. If I did load them dynamically, would they play at their original frame rate?

Understanding compositions with different frame rate

Hey everyone,
I am working with AVCHD footage with a frame rate of 25.
If it drop my footage into a new compostion after affects sets everything
up automatically.
I'd now like to what happens to my avchd clip if I change the frame rate
of my compostion from 25 to 24. What excatly happens to the frame
missing? Does AE just gets rid of it?
Does it make a difference if I just change my comp settings from 25 to 24
or if I drop my 25 comp into a new one with 24.
Thinking of it the other way around, if I change my frame rate from 25 to 50,
does that mean that AE doubles the frames of my files?
In general, does the changes have any impact on the speed of my footage?
I'm looking forward to your reply. Much appreciated.
Best,
Alex
PS: this count for Premier Pro aswell?

When you create a layer in a composition, and that layer is based on a video footage item, the composition checks at each composition frame to see (sample) the data from the footage item. If there isn't a single frame of data from the footage item that exactly lines up with the frame in the composition, then the composition samples from the footage frames on either side and does one of several things: It can either just pick one of the two frames, or it can just mix them together, or it can do something much smarter and try to reconstruct the image that would have existed between the two frames.What it does depends on what frame blending setting you're using.
When you're using a footage item that has a higher frame rate than your composition, and both frame rates are relatively high, you don't need to worry about this at all, as the default settings tend to work just fine.
To sum up, changing the frame rate of the composition just changes how often the composition samples the image data from the footage item. It does nothing to the footage item itslef and doesn't affect how fast the video from that footage item plays in a layer.
To interpret a footage item as being at another frame rate, or to conform a footage item to a frame rate, you have to use the Interpret Footage dialog box.
For more information, see "Frame rate".
