From 60p to 24p...

Hi guys, with new FCX how do you now conform 60p into 24p? Thanks a bunch !

@RedHavoc
Yes. I downloaded Final Cut Pro X this morning and created a project with a frame rate of 24p. I imported footage shot on my Canon 7D @60fps. I dropped a clip in the timeline, selected it, went to Modify>Retime>Conform Speed and it retimed the footage to 40% of it's original speed.

Black frames at the end of an exported file when converting from 60p to 24p

I have another export issue that I can't figure out.
I import footage I shot at 23.98fps (on a JVC HD100) using a Kona LH card at 59.94fps DVCPro HD, in which it has a 2:3 cadence. I need to make files that are actually 23.98p DVCProHD. Unfortunately, when I export in Final Cut from the 59.94 original, the new 23.98 file has all of the image, exported correctly, followed by a number of black frames such that the total number of frames in the exported file equals the number of frames in the original file. That is:
If the original 59.94 file was 3s long, that is 60 * 3 = 180 frames. The exported 23.98 file also has 180 frames, but only 3s of image = 3 * 24 = 72 frames, followed by 180 - 72 = 108 frames = 4s 12frames of black.
How can I prevent this from happening, and end up with an exported file that is (e.g.) just the 3s of image, and not 7.5s of which 4.5s are black?
It's true that I can manually clip this black off, but I need to do many clips as a batch, and would really not have to change one clip at a time. It is also true that I can do a batch in compressor, and that this process does not suffer this problem -- that is, there is no extra black -- however, there is another problem: the original 59.94 DVCProHD files are actually 1280x720 with square pixels; the files exported from FCP via the KONA DVCProHD codec maintain this true HD proportion, but the ones exprted through compressor (which does not appear to support the KONA LH implementation of DVCProHD as an option) have the size 960x720 with anamorphic pixels, and I would rather keep the original size. Thus, I would rather export from fcp. If anyone has any insight into how I might resolve this....
Thanks,
Robert Schaller

Thanks. If I understand you correctly, it does seem to export correctly if I paste the 59.94 clip into a 23.98 sequence (you can't nest sequences that have different time bases) and export from there, and it doesn't even have to specify square pixels, etc.: the AJA codec implementation seems to take care of that. There is no longer any extra black, so, per file, that gives the right result.
That, however, is only one part of the problem, though a significant part. Next is, I really would like to do this as a batch process, as I tend to have many clips to do at one time. As soon as I try any kind of batch export, I end up with one of two problems:
1) if I try to batch export from fcp, I'm back to having extra black frames, or
2) if I try to batch export with compressor, I get 960x720 files.
If anyone has any suggestions on how to get the right files in a batch, that would be the next step. Is fcp scriptable? And, if so, can you write a script that takes a clip, pastes it into a blank 23.98 DVCPro timeline, sets the correct in and out points (i.e, in at the beginning and out 1 before the end), exports it with a specified codec and time base, with a name based on the source clip, and then repeats that as needed?
Thanks for any input --

Converting 30p/60p to 24p

hello
i am trying to convert my 60p footage from my Canon 7D to 24p to get that "film look". If i simply drag a 60p clip into a 24p timeline, will it automatically convert it to 24p?
This seems to make sense, but Philip Bloom on his web site has this long process of conforming it to 24p in Cinema Tools, then speeding that back up in Compressor to match the original timing. Does it have to be done this way or can i just drag it in?
thanks
heres the link for philip blooms workflow:
http://philipbloom.co.uk/tutorials/canon-5dmkii-tutorials/how-to-convert-canon-5 dmk2-footage-from-30p-to-24p/

be aware, the "film look" has much less to do with the frame rate and more to do with cinematographic elements like depth of field, lighting, and grain. Even if you convert 30 to 24, you still had a shutter speed of 1/60th of a second, so the individual frames have less motion involved than if you had a shutter speed of 1/48th of a second.

How do I convert frame rate from 30p to 24p????

I am about to start post on a short film shot on the mark II. I am going to convert the footage to ProRes. The director wants the "film" look. Can I change the frame rate from 30p to 24p in compressor? Are there any key settings I should know about?

There are lot of different ways to go about it, all have mixed results, and there is no way you'll get flawless results. However, here's a few ways to try:
A) Conform to 23.98, using Cinema Tools - You'll be slowing down the footage, so this is no good if you have on-set dialogue recording you're going to keep and need lip sync. If you weren't going to use any on-set audio and doing all dialogue and FX replacement, it wouldn't matter. This is also effective for music videos - just speed up the audio playback while shooting, and when you slow the video down in post, it'll match.
B) Use retiming in Compressor - I believe this uses some advanced frame blending and optical flow - I've had decent results with this method, but you can end up with some artifacts on high motion material.
C) Use Twixtor within FCP or Adobe After Effects. This has been my preferred method for surgical speed manipulation. It's time consuming and just like method B, you'll get artifacts on high motion material.
What you definitely do NOT want to do is drop your 30p footage into a 24p timeline. The motion will be horribly stuttery. Similarly, don't try to just use frame blending to achieve the frame rate conversion - it's not very impressive to see frame blending all over everything.
You're best results will come from having low motion footage. Interviews, head shots, etc. work great. If you're doing a lot of action, I'd advise against trying to convert using anything but method A. If you can get your hands on the 7D, you can shoot 24p natively.

How to create subtle slowmotion from 30p to 24p?

Hi,
What's the best way to create a very subtle slowmotion from 30p to 24p in Motion? Is it to create a 24p project, import the 30p footage and then change the timing speed to 80%? Do I have to use any kind of 'frame blending'?
Thank u very much for your answers!

Select your imported video. In Properties > Timing... slow down the video Speed to 80%. You can apply a frame blending from the dropdown (if you want to... try them out!) but I don't see where you'd have to if the playback is 24p, unless you want to add the effect to the video (optical flow might be interesting).

Converting 720/60p to 24p

Im using a Panasonic HMC150 and shot some footage in 720/60p so I can try out the slow motion effect. How do I convert the clips shot in 720/60p to 24p using Final Cut Pro? I don't know how to set the timeline up to be 24p. Is it just a matter of getting the footage in the timeline and changing the speed?

YOu use Cinema Tools. Tutorial found here:

Combining 24p from V1U with 24p from VX100

As I understand it, 24p is not 24p is not 24p, and there are some issues that might arise from mixing 24p from two different brands. Is this the case? If so, what is needed to be able to capture and use the footage from a Sony 24p and a Panasonic 24P. A plug in? A setting? Hardware?

It there/was there a problem in the past with Final Cut Pro capturing 24 P from the V1U? We had heard there was. but we are not clear what that problem may have been or how it manifested itself?

60p to 24p Pulldown Conversion - Best Settings?

Our studio recently purchased a new camera for some run-and-gun shooting. Unfortunately, it does not support 24p natively, only 60p & 60i. It does, however, support shutter speeds from 1/2 all the way to 1/4000. What advice can you give regarding pulldown conversion into a 24p project, both for camera settings and FCPX?
Please note that I'm looking for 1:1 speed, NOT slow-mo.

Shane, I understand the difference in motion. And as I said, it was not my intention to capture at the frame rate that I did. With regards to the slight stutteryness, I'm comparing one of these problem clips to an actual 24pN clip from an earlier part of the shoot. I put both in the 23.97 timeline, but the one captured at 60p feels like it should still run slightly smoother or with a little bit more motion blur maybe. I think I'm simply looking for the best way to cheat that "look" back into the footage.
Your post below is right. Cinema Tools is not a good option for that as this doesn't really have much to do with 2:3 3:2 pulldown type operations and it won't let me conform the footage anyway.

Conform Speed- 60p to 24p

Hi guys, one feature that nobody seems to be talking about is the "conform speed" from the speed-popup-thingy, I love I can conform to 24p for true slow mo when I shoot 60p (avoiding to go to Cinema tools, not to mention the native ingest of my DSL footage while transcoding in the bg)
But I'm not sure if one should use the "rate conform" of this conformed clip (in the inspector) at the default 'floor' or at 'nearest neighbor'.
What would act like a simple frame by frame conforming without introducing any artifacts? In my tests it seems that "nearest neighbor" is more appropriate but I could be wrong...
Any ideas?

60p to 24p

Hello all,
I recently shot some footage with an HVX set at 720p24, but the gremlins in my fire-store 100, for whatever reason, told it to start recording at 720p60 halfway through my shoot. By this I mean, that the footage has 60 individual (no duplicate) frames with the time code at 59.94.
What's the best way to re-conform this to 24p to match the rest of my clips? I've read about people doing this with compressor or with something called a Natress filter, but I don't know the specifics of either route. Have any of you done this and had the resulting 24p clip play back smoothly?
Thanks.
Ben

833x480 from 60p

I normally edit with FCP7, but FCP7 will not import HDV footage properly, it's all buggy and normally I have to go to Imovie when I tape in 30P. There's never any issues getting 1280 x 720 video with Imovie, it's only now that I taped something in 60p that the capture is not getting the full aspect ratio.
I'm seeing everybody post that Imovie is downgrading their video to 960x540 at times generally when they've captured 1920x1080 footage
Imovie '09 is downgrading my hdv60p video to 833x480 even when I selet "full" in the capture settings upon capture.
In the past when I taped in hdv30p Imovie 09 would capture the full image at 1280 x 720 no problems.
Is there another setting somewhere that I'm missing?
Thanks for any info

How to convert 60p to 24p?

We are shooting with the HDX-900. Mostly 720p. Our deck is the
Panasonic AJ-1400. I'm looking at wanting to convert footage shot at
60p to 50% slomo.
Anyone have any ideas?

In the Browser, does it say 59.94 for the frame rate? If so, then it is some hiccup. I hit this every now and then. In this case I would then use Cinema Tools to OPEN the clip and then CONFORM it to 23.98fps. COPY IT FIRST...it modifies the clip destructively...meaning it will be slow motion now forever...no going back.

How can I copy the config from one SF300-24p to another?

I can download the config, but do not see any upload options.
Fred

Fred,
The saved config is a text file.
You should be able to backup a config to your desktop and restore it to another similar unit. I hope..
let me know if you have any problems. See my screen shot below;

720p60 3:2 Pulldown to 720p24 in Final Cut?

We shot a feature film with a Panasonic Varicam at 24p and captured directly to a computer via HD-SDI through a BlackMagic Design Decklink HD Extreme using Apple's ProRes codec (looks fantastic by the way... for those interested there is definitely a visual difference between DVCProHD and ProRes when capturing from an uncompressed source). The transport mechanism was 720p60 because that's what the Varicam outputs, and Final Cut's capture doesn't pay any attention to the HD-SDI meta-data (if any exists) so the pulldown frames were not removed in the capture process.
So, now I have all of this 60p footage that has superfluous frames added in the 3:2 pulldown process of the camera. When we edit these clips within Final Cut in a 24fps timeline, about a fifth of our clips play back stuttered as they are dropping, or more accurately doubling, every other frame and ignoring those in-between. I've figured out the reason for this is because Final Cut has no clue what frame of the 3:2 sequence each clip begins with and thus thinks each clip begins on an A1 frame. In 4 out of 5 frame sequences, this is fine, as shown here:
Normal telecine sequence:
AAA BB CCC DD EEE FF…
Edit starts on first frame:
AAABBCCCDDEEEFF
ABCDEF
Edit starts on second frame:
AABBCCCDDEEEFF
ABCDEF
Edit starts on third frame:
ABBCCCDDEEEFF
ACCEE
Edit starts on fourth frame:
BBCCCDDEEEFFG
BCDEFG
Edit starts on fifth frame:
BCCCDDEEEFFGGG
BCDEFG
As such, we see a stuttering issue (which appears as 12fps... every other frame is ignored of the original footage) on all clips that begin with the 3rd A-frame because Final Cut reverses this pulldown automatically but assumes that the beginning of the clip is at the beginning of the sequence every time, when it's not. I had hoped that I could somehow change the starting pulldown frame within Final Cut but see no way to do this. Cinema Tools doesn't have any good tools for working with 60p original content, so I'm stuck here.
I downloaded and installed the Nattress Standards Conversion filters and have experimented with them but have not been successful at eradicating this problem entirely. It seems its conversion from 60p to 24p assumes 60 unique frames, not a 3:2 pulldown clip. This coupled with the fact that Final Cut has some flakiness with its handling of the pulldown in general leaves me seeking the best strategy for handling this from wise council, which I would absolutely this forum to be.
Thanks for any help in advance!

Alex, thanks for your help. I didn't notice one of the FCP settings for my camera had been changed. Funny how working at 2:45 a.m. can sneak up on your brain.
Thanks again & take care!

Canon 7D 720/60p converted to 720/24p in Premiere Pro CS4

I've exhausted all my resources trying to find a simple answer but it seems like anything regarding 60p to 24p is about slow motion video which I already know how to do and understand thoroughly.
My question is, with my Canon 7D, there's no option for 720/24p (23.976), there's only 720/60p (29.97) or 50p. Getting 30p video is simple because Premiere just drops every other frame. Now 24p is a little trickier. There is an option for 1080/24p which is overkill for what I want and need to do. I also don't have the capacity in memory cards for that.
I understand that if I drop a 60p video on a 24p timeline, Premiere will just drop frames. But since 60 is not divisible by 24.. how does Premiere know which frames to drop? I believe there's also a Frame Blending option as well.. how would that work?
I'm looking for the best way to convert 60p video to 24p in Premiere. I can't imagine it being overly complicated.

Thanks for the reply but I'm not sure who told you that 1080p24 produces smaller file sizes than 720p60.
Canon 7D has a max recording limit of 4gb (per file) due to FAT32 file system restrictions. At 1080p, 4gb = 12minutes. On a 16gb card, that's only 48minutes. At 720p, 4gb = 30minutes. That's 2 hours.
Then it's Canon's encoding scheme or sensor use that makes such a huge difference. My AVCHD files from a Panasonic HMC150 are smaller at 1080p24 than at 720p60. Which makes sense since the raw pixel count per second is less with 1080p24 (49,766,400 at 1080p24 versus 55,296,00 for 720p60).
I have a tutorial on my web site about using dv2film, which is designed to convert 60i DV to 24p DV. But it also works for HD footage. Check it out and let me know what you think.
