30p fps to 24p fps when no interlace is involved

Hello: I've shot my clip in 720p60, then uncompressed it, edited it in FCP in a 29.97fps timeline sequence, export (using QuickTime Conversion) as H.264 at 29.97fps and the result is very smooth. When I export as H.264 at 24fps the result has a slightly jerky motion (possibly because every 5th frame has been deleted ???). What is the best method to convert from 30p fps to 24p fps (no interlace is involved) ? Thank-You, MLR

Broadcast stations won't EVER want to air things in 24 fps. Here in America, when they get 24fps material they do a process called telecine and ADD (or Combine) frames to get it to 30 anyway.
Leave it at 30.
Now, if you edited in 24 with native 24 material that would be a different story. You could add the telecine cadence onto your video and make it just right with a 'film-look'.
Here's what I suggest you do...
Call up MTV and ask them to send you their BROADCAST SPECS (often called a red book... or white book). They'll be happy to point you in the direction of it.
Also do it for PBS and maybe Discovery Channel.
Read EVERY word. Will be an education you couldn't EVER pay for. Might also open your eyes to how far over your head you might be.
Good luck...

24 fps to 25 fps please advise

Hello,
I have a project which is recorded with HD camera, captured as 10-bit uncompressed, but most of material was recorded at 25 fps, some at 24 fps. I need advise how to convert 24 fps to 25 fps, i tried Compressor with duplicate 24th frame option, but that looks bad. Anyone have suggestion how to convert it????

You may have better luck pre-exporting media with compressor if you nest the clips into a 25 FPS sequence first. New frames will obviously need to get created, but turning on the frame controls in compressor can give you smoother results, though it'ss probably increase your encoding time significantly.
Another option you might try testing out is to re-conform the clips to 25 FPS in Cinema tools. This will effectiively speed up the clips, and the audio to match, with a slight pitch shift, however, this conversion is practically instantaneous and can be done in a batch. Keep in mind that this will most likely reconform the existing clips, so you may want to create some QT refrerence movies to reconform, particularly if you have started editing with the 24p clips - a reconnect won't be possible once the frame rates have changed.
Hope this helps -

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.

Convert 24 fps to 25 fps project.

I have accidentally made some recordings in 24 fps.
The need for a film which should also be on television - in a 25 fps project.
So the problem is that I have both 24 fps and 25 fps in the same project. it gives strobe flashes. Is there a way I can avoid it?

Personally, I'd say you're massively hosed...
You could try optical flow retiming - available in Motion/Shake/Compressor to generate new clips with the proper frame rate. But that takes a lot of time. Can you post an example of the flashes you're talking about?

Movie fps VS playing fps in quicktime inspector

using a 30FPS movie as example...
movie fps is the real FPS of movie.
playing fps is the FPS of:
A. the movie actual playback FPS (meaning even though it says 30 FPS it might not be)
B. the movie is indeed 30FPS but playback FPS is just FPS of playback as effected by system performance in qt player. but in an NLE it will playback true 30 FPS

The actual FPS might be 30, but the Inspector in QT Player will tell you how fast IT can play back the video. Might be 30fps, might be 27fps...whatever it can do. But the actual REAL FPS will still be 30fps.

Converting 30 fps to 25 fps

hi,
I shot some multicam footage on 2 7d cameras one was unfortunatly 30 (23.97) fps and the other 25fps any advice as to what would be best way to convert the 30 fps to 25 fps ?
I need to multiclip it in pro res 1920 x 1080 progressive sequence.
many thanks

It can't be real 23.976. It has to be 29.97 with advanced pulldown, so recorded at the higher frame rate. You couldn't tell a one frame speed up, not slow down, by listening to it.
I think Graeme's tool is worth it, both for quality and equally importantly for speed if you're doing a lot of material. Compressor can be painfully slow.

You shoot 24p, 25p, 30p but iMove 09 treats it as interlace! Why?

If your HD camcorder can shoot “1080p25” (progressive 25fps) or “1080p30” (progressive 30fps), of course you want to shoot using these frame rates. The Canon HV40 and Canon HF S11 are examples of HD camcorders that can shoot progressive video at 25fps (in PAL regions) or at 30fps (in NTSC regions) in addition to “1080i50” or “1080i60.” They can also shoot 24fps.
When you shoot 1080p24, 1080p25, or 1080p30, in most cases progressive video is recorded as interlace video. Both 1080p24 and 1080p30 are recorded as 1080i60 while 1080p25 is recorded as 1080i50.
When iMovie 09 imports this video, it will treat this progressive video as interlaced HD. Unfortunately, iMovie treats interlaced HD badly. If you Stabilize a clip, employ a PIP or Crop, add a Ken Burns effect to a video clip, or use a Wipe or Pseudo-3D transition (such as Cube)—iMovie on-the-fly converts your 1080-line video to 540p (960x540) video. Therefore, all 1080i clips in your movie will lose up to 35% vertical resolution and up to 40% horizontal resolution. This loss of resolution will occur even if you add only one of these effects.
But, what if iMovie didn't do this?
What if iMovie correctly saw progressive HD as progressive HD -- not interlaced HD? This would allow all scaling FX to be used. Moreover, because you ARE shooting progressive HD, NO scaling artifacts would be introduced!
Would this be a benefit to HDV and AVCHD 1080i shooters?
Absolutely! Especially if all this could accomplished without wasting time and image quality recompressing your video.

The Pana 300 is a great camcorder, but I wish it shot 30p. If you want a Cine look you'll have to shoot 24fps rather than the easier to use 30fps.
Anyway, about removing pulldown:
1) You CAN remove 2-3 pulldown. But, it requires a recompresion from AIC to AIC after your clips' AVCHD is converted by iMovie to AIC. This would provide real 1080p24. I call this "TRUE 1080P." But, with a MacBook this might take too long. And, you lose a generation of quality!
2) A better solution is to get iMovie to treat your video as though it has no pulldown and is progressive. I call this "FALSE 1080P" because once 2-3 pulldown is added during recording, the video has BECOME interlaced. (I'll explain about this in my other thread on dealing with 1080i50 and 1080i60.)
PS: The reason I prefer to shoot 1080p30 is because then the goal is to get iMovie to treat 25p/30p video as though it were progressive. I call this "TRUE 1080P" because it really IS progressive.
We know what it is, but iMovie doesn't. And, how can iM since it is recorded as 1080i50 and 1080i60. It's too bad Canon and Panasonic record 25p/30p as interlaced. The neat thing about TRUE 1080P is that after editing as progressive you can export as 1080i or 720p. And, no matter what FX you use you'll never get scaling artifacts!

Does the video's FPS play a factor when exporting in a higher FPS?

The reason i am asking is becuase by now i have a theory but i need it confirmed. the video i am using runs at 24FPS average but i am rendering out in 30FPS. now the issue that comes into play is the fact that the video and audio drift out of sync in parts and gets progressively worse as time goes on. is this because of my export FPS is higher than my video's FPS or is this a common issue with any type of exporting?
Needless to say i don't need to state my specs as i have already ruled that out.(not pc illiterate) I know for sure this is a software specific issue due to the fact that i have no had this issue before till now.
It might be an interesting fact to say that i am using cartoon animation and syncing live recording clips to the animation.

A bit of an update. i'm on a much more updated PC now and now i'm running into a new problem on top of my previous one. when it comes to exporting MP4 files, it does not matter what encoder i use, adobe will ALWAYS shrink the video and cut off more than one minuet of video. the enitre episode is there, but it's for some reason or the other speed up the video. why is this happpening? and if ANYONE was paying attention to my ealier post:
I AM CLIPS FROM AN ANIMATED SERIES THE FOOTAGE WAS NOT SHOT BY ME
the frame rate for the footage is in 24FPS as i said ealier. the video is perfectly sync'd with the audio on the timeline, yet it ALWAYS DRIFTS out of sync as well as shrinks my video down. can ANYONE who KNOWS what they are talking about when it comes to adobe priemere pro explain to me why this is happening and how i can fix it?

Why does premiere elements 8 change a 29.97 fps to a 25 when conforming?

I have a project setting of NTSC HDV 1440 x 1080 with a frame rate of 29.97. when i import video, it conforms and indexes it and then suddenly the frame rate is no longer 29.97 but 25? why does it do this?

Best continue this discussion in your other thread in which the matter was brought up
http://forums.adobe.com/thread/1404750?tstart=0
In your original thread, please see my latest reply and some mini checks to detemine the cause of what you are describing for file frame rate being converted from 29.97 to 25 by project conforming.
Thanks.

No support for 24p camcorders? (de-interlacing, 3:2 pull-down)

I have the Canon HV20, which is not a new camcorder by any measure. It captures video in 24p (which is great for low-lighting conditions), but then writes it to tape in 60i. This is similar to how DVDs send cinematic video to your television.
Alas, I can't get iMovie to handling this video (and probably any interlaced video). I've tried exporting it to Quicktime (full 1080 resolution) at 24fps, and the output looks like crap due to incorrect de-interlacing or 3:2 recognition. Even if I open the original raw capture using quicktime and step through the "frames", quicktime shows 2 out of every 5 "frames" interlaced, since it incorrectly identifies the video as 29.97 fps.
Is there any way to use iMovie with interlaced video? With 24p recorded as 60i? Will Final Cut Express do any better? Thanks in advance.
Another possibility, can I export the video as 60i and let my TV or PS3 perform the 3:2 pull-down?

Are you familiar with 60i video? If the source video isn't de-interlaced, it's going to look bad even when exported uncompressed, assuming your exporting to some progressive scan format such as 30p or 24p.
2 out of every 5 frames (at 30fps) look like the ball on this webpage:
http://www.labdv.com/leon-lab/video/interlace_en.htm
There is a form of deinterlacing available when exporting to QuickTime. This solves the problem if I wanted a QuickTime container, but the option isn't available when exporting to MPEG-4.

30 fps to 25 fps

Does anyone know what settings in PPCS4 would give smooth playback when converting 30 fps footage (from Canon 5D MK II) to 25 fps? Every setting I've tried gives jerky output. I also tried the ConvertXtoDVD program, and it works beautifully out of the box, with very smooth DVD playback.
In the very near future, I need to mix Canon HV20 (25p) and 5D (30p) video,
so converting the 30p footage to 25p should be the first step, final output being a PAL DVD and a blu ray disc

Prateek, the 30fps to 25 fps conversion kind of works, but the output is jerky/choppy. It is playable, but not pretty to look at, because motion is not smooth like in the original 30 fps clip. It does not matter what the output format or media is, the result is the same. A search on the net suggests that there are some more intelligent ways of doing the conversion than the one implemented by premiere's mainconcept codec

50 fps to 25 fps, twice as slow... how to?

Hi all,
First of all : I am a total video rooky. But my friend let's me play with his Final Cut Studio this weekend as to explore what I can do with high frame rate video. Now, can somebody tell me what the best way is to achieve this :
25 fps video output
lossless codec
easy to work with in AE
input:
slowmo video file shot on Canon 7D
1920 x 1080
H.264 codec Linear PCM
colorprofile 1-1-6
bitrate 47.393
Goes without saying that I want no frame loss, and of course the output can be slower.
Thanks!
Alex

If you used a Canon 7D and shot at 1080p you either shot 24p, 25p or 30p (29.97)
If you shot at 50p (or 60p) you shot 1280 x 720.
These are the only frame rates and sizes this camera shoots in HD.
You need to convert the H264 to an editable format before you can use it in FCP, preferably an Apple ProRes format.
If Cinema Tools is outputting a 1280 x 720 frame size that's most likely what you have input.
Open one of the original H264 files in Quicktime, in the menu bar select WINDOW > SHOW MOVIE INSPECTOR this will show exactly what the frame size and fps is.

3:2 pull-down from 30 fps to 24 fps while capturing

Urgent !!
When opening a new NTSC premiere project, I can choose either 4/3 or 4/3(23,976 fps) which is supposed to do an automatic 3:2 pull-down removal in order to obtain a 23,9 fps progressive clip. This is very important because numerical work on progressive frames is much more precise and artefact-free than on interlaced ones (NTSC is interlaced).
But when I choose this option, I can't drive my device anymore, and can't capture any frames (in this case I'm using a black magic SD pro card).
So, this option doesn't work. What can I do, expect capturing my clip in regular 4/3 and transfering it to After effects(that I heard can actually do this pull-down process)?? This is much longer, I whant to make this pull-down removal while capturing !!!
Help!!!

My understanding is that pulldown removal happens during playback of the file, not capturing, which is simply a straight digital copy of the original.

50 fps to 25 fps

Hey
Ok so i decided to keep my videos in 25 fps (it was shoot in 50 fps) , im using compressor for rendering, should i do anything to get the video more smooth? because when i try to render from 50 to 25 fps it doesnt look good. Which option should i use?
thx

You're in the FCS forum, not the FCPX forum.

HD 24p from V1U has interlacing artifacts

I am just starting to play with my new Sony V1U. I shot a few clips at 24p and brought them into FCP. When I look at them on a 24fps, I still see interlacing on every 2 of 4 frames??
The clips themselves are still listed with a 29.97 timebase, but I can't figure out how or if I should change this. The Capture Preset is set for HDV. (There is no option for 1080p24)
Shouldn't I be able to see all 24 frames progressive in the timeline? Any ideas?

I just purchased a V1U myself. Just getting FCP 5.1.2 is NOT going to fix your problem. FCP doesn't support the V1U's true 1080 24p yet. The only HDV that FCP is referencing when you see 1080 24p is the Canon 24f thing (shutter of cam isn't true 24p, it is a software-in-the-cam solution, albeit a very convincing one...)
Anyhoo, I had success pulling the 29.97 footage down and removing the 3:2 cadence from my V1U footage. The result was squeaky clean 24p. Looks great. You'll need to use cinema tools and AIC instead of HDV (cinema tools won't let you apply pull down to frames that don't exist, so native HDV is no good; you'll need to make all your frames I frames...) I've already started using the cam's 24p scan A mode to make this easier (it resets the cadence every time you pause the camera...)
If all this sounds completely foreign to you, I advise just waiting a few months for Apple to officially support it in a future FCP release, so that FCP will remove the frames on capture.
