25p to 24p audio?

I have been trying for a week using soundtrack pro to conform the sound of a 25p 1.5 hr movie to 24p.
Used cinema tools to get the video 24p (23.98 on the FCP timeline) but can not seem to get the audio to sync up properly.
I tried process>time stretch and set it to the exact hh:mm:ss:ff that is the end of the movie in the 24p FCP timeline but that doesn't seem to work. (in soundtrack)
Anyone have a way to do this in FCP? in Soundtrack? In Logic lite? any other app?
your advice will be much appreciated.. supposed to be getting this thing out on DVD to many many people but can't get the audio fixed
thx

Why do you need to conform anything? Depending on your release needs, the audio can remain a separate file. The length of your sound track won't change regardless of the frame rate; 90 minutes of 25fps is the same amount of time as 90 minutes at 24fps.
Again, my apologies for not knowing anything at all useful about your problem. Last time I shot double system or had to convert from 23.97 crystal to 29.97 NTSC was maybe 20 years ago.
Best of luck, please come back and close the post if you get it figured out.

Convert 25p to 24p ... I *want" to slow it down by 4%. How?

I have a FCP timeline in DVCPRO-HD 1080i50. Footage is shot in 25p in P2 format.
I would like to convert to 24p. And I would like the converted timeline to be 4% slower. And so each frame is preserved and unaltered.
I've looked at exporting to Compressor, but the conversion appears to "mess around" with the frames in order to not end up 4% slower.
Is there a way to re-time each frames, and slow the timeline down by 4%?
Many thanks.

I exported the 25p clips as a self-contained QT file. Then I brought it into FCP and used Cinema Tools to Conform to 24p. Then I exported it again. The result: the 25p file and the 24p file were the SAME duration. In other works, it has not slowed down by 4%.
I need a way to change from 25p to 24p by matching frame by frame, so that the 24p video is 4% slower.
Any help appreciated.

25P to 24P conform audio?

I have been trying for almost a week now to get this done for a 85min movie. I am bringing in the .aif from the 25P movie (exported as aif from FCP). Then once it loads up I select process and time stretch. then i set the hh:mm:ss:ff to be exactly how long the movie is in the 24P timeline in FCP (actually a 23.98 timeline). I also set the STP prefs to be 23.98.
I have tried now so many times and can't get the sound to sync up.
I read something about slowing down 4%. Maybe, I can try that. but how?
or maybe i should be using frames?
I read that STP automatically adjusts the pitch too. Does anyone know about doing this as well?
thanks in advance. totally confused.

23.98 vs. 24p audio

hello,
i have been having a lot of trouble matching my audio exports.
i am working with a 23.98 timeline with 24pa footage shot from the DVX100.
my sound engineer is working with a 24p timeline, so i have exported video and audio for him to work with under 24p video and audio.
the aiff exports, however, will not match my 24p video. even if i export the aiff in the 24 timeline, it wont synch with the 24p video.
the video is being exported at DV 48k-24 and audio is 48k stereo.
can anyone help me?
thanks,
steve

Yes... we are running into a variation of this as well. Very frustrating... it didn't happen to us before Quicktime 7. We are also using a mixed Windows/Mac environment, and it seems that we are unable to make a true 23.976 (or even a 23.98) fps movie with Quicktime no matter what. They seem to always come from a Windows machine with the FPS set to 23.99. This makes our conversions balk as well as our Final Cut system. What we are doing is taking a series of special effects digital dailies compressed in H.264 (or Sorenson), sent via FTP, and then converting them to DV for editing in Final Cut (4.5). When doing the conversion, we now run into any number of problems, including a doubling of frame 19 so that frame 19 and 20 are identical, and this continues through the shot. We also have Final Cut kicking back shot to us that don't have the new "Aperture display" feature not set to "classic"... a neat feature, but not at the cost of breaking a well-honed workflow.

Importing 24p audio falls out of synch

Hello,
I was just capturing two tapes of a musc video, using a panasonic GS500 to import, shot in 24p on a DVX100, and captured on the standard DV NTSC 48 kHz preset. When I watched my clips afterwards, I found that the audio falls out of synch in the longer clips. I don't understand why this has happened, because I thought the 24p was still recorded on the tape as DV NTSC but with a 3:2 pulldown effect on it. My question is how can I fix this importing problem so it doesn't fall out of synch again when I re-import?
Thank You,
Kyle

This can happen with long captures. Better Camera/deck seems to be key here.
For now, you could select the clips that drift and do a 'File'/Export as AIFF...48khz/16bit. Then re-link/replace the new audio with the original video files.
Recapturing in shorter clip length may avoid funky Aud Rates. Either way, you'll likely need to create new multi-clips and edit with those.
Within current multi-clip sequences, you can control-shift/drag left or right on an angle in the viewer to bring the sync back in line. This should only affect the angle/clip following a cut, and not the sync prior to a cut.
If you've already made many cuts througout the timeline, you could use the 'slip' tool on out of sync clips after you've collapsed the multiclip.
Hope that helps,
Kevan

30P to 24P audio problem

Hi all,
quick question that I cannot ind an answer to: I shot at 30, and I want to slow it down to 24 for a slight slow mo look, I right click the file in PP, interpret footage-23.98 then try playing it in the source monitor, it looks and sounds great (albeit audio that sounds like Barry White) Once I drag it into the Sequence which is at 23.976, the video looks the same, but the audio is early by several seconds (still Barry Whitish, but very off)
Any ideas? I need the slow audio synced in the final output so I can re-do the vocals and match to the slowed down mouth movements.
I'm on a Mac 2008 8 core, Snow Leopard, 12 GB RAM, etc.
Thanks!

Don't use Interpret Footage. Right click the clip and change it's Speed/Duration.

24P Audio Problem on burned Disc

I have an asset that was shot and compressed at 23.98. When I bring it in to Studio Pro 4 it plays fine ... audio is synced and all is good. (Although, the inspector says it is a 29.97 file ... I assume this isn't an issue though ... I can confirm that it is compressed at the correct fps.)
Anyway, once I burn the disc the audio seams a hair out of sync with the piece when played on external DVD players ... confirmed on multiple DVD decks. Maddening! Lips don't quite match. What in the heck am I doing wrong?!?!
Thoughts anyone?

Is the audio lagging or in advance right off the bat, and remaining at the same rate of missmatch throughout, or is it slowly going out of sync?
Is the audio AIFF or AC3?
If AIFF, this may be the problem even though the format is in the DVD spec.
Are you viewing on a consumer large screen (42" or larger) LCD or Plasma?
Some displays without lip sync adjustability built-in will pass the audio milliseconds before the video (always before, not after).
Improper lip sync drives me crazy watching network TV.
( and a few commercial DVDs as well)
The standard is too loose.
I use a Felston DD540 to correct the audio on some channels.

PAL (25p) - 24p - NTSC DVD

I have two CanonXL1e (PAL) cameras. I am planning to shoot footage at 25p and conform the clips to 23.98fps, edit in FCP on 23.98fps sequences, and then output to NTSC DVDs at 23.98fps.
The audio gets out of sync when I conform the 25p clips to 23.98fps and drop them into a 23.98fps sequence.
The audio stays in sync with the video when I conform the 25p clips to 24fps and drop them into a 24fps sequence. The problem I have with this setup is when I export the 24fps sequence from FCP to Mpeg2 using compressor I seem to drop a frame every once in a while. Is this because it's going from 24fps to 23.98 fps?
What is the correct workflow to get from PAL 25p to 24p to NTSC DVD?

I have not - but instead of conforming to 24, does cinema tools give you the option to conform to 23.98? If not, I'd have to think it's like Dropframe/Non-Dropframe sync issues - stuff drops out at the rate of 2 frames per minute. Not noticeable in the first minute, but definitely discernible after 3.
I don't know of any option other than to run the audio at 99.9% or slipping the audio every minute...
Or is that 100.1%?

Convert 25p clip to 24p via AE and Dynamic Link

I heard somewhere that AE is great at converting 25p to 24p and vice versa. If I have a clip or clips in my 24p project which filmed at 25p, can I use dynamic link to send them to AE, convert to 24p there, and end up with a perfect 24p project?

depends on your needs...
1. You can use AE to conform a clip via "optical flow" to a new frame rate - that works great for single short clips and you have to supervise the process and tune settings to prevent motion artifacts (the process generates new synthesized frames by morphing) Don't use dynamic Link to embed it in your timeline - just render out a new conformed clip - less problems - more speed...
2. You can use the "Interpred Footage" option in Premiere and set the framerate of the source clips from 25p to 24p this is simple and you just can use the clip in your 24p sequence. The audio will be streched and that can result in a too low pitch. In this case you can use Adobe Audition to do a HQ audio conform with pitch/stretch compensation.
--> !Attention! If you use "Interpred Foogate" and change the frame rate Premiere will loose the adaped timing for multiple audio tracks in the soure file after reloading a project - check audio sync all the time if you use this feature or replace the clip audio with external audio files...

Audio sync problems. Need some advice!

I have a project with 25p files from a D7 camera. The external recorded audio is synced with PluralEyes, with the audio/videosettings in FCP set to 24p. So I have 25p video and 24p audio. The audio is drifting and I have green lines on the audio showing that there is a problem.
Is there an easy way to fix this? Can I convert the audiofiles in some way, and reconnect in the timeline?

Have you tried using cinematools to conform the 25p material to 24p. Be sure and duplicate your files before testing.

What to do with one 25i and one 25p file in same Timeline???

Hey!
I was bothering you with questions of how do I put 30p and 25i footage together, but things have changed. [i]HUNTREX and ANN BENS, thanx a bunch for your help)[/i]
Canon released new Firmware for its 5D MkII camera, so I can shoot 25p and 24p... But now the problem is still there!
Now I have Interlaced and Progressive footage to put together!!!!
I also decided to get Cineform NEOSCENE which converts both MPEG-2 from my Sony FX-1 HDV camcorder and AVCHD (H.264) from Canon 5D into CINEFORM-AVI...
So, to avoid mixing formats in codec part - I ended up with those AVIs!
So for the first time yesterday I imported AVI-s made by NEOSCENE from both my FX-1 25fps (1080i) Sony camcorder and my 5D MkII 25fps progressive (1080p) into my PREMIERE PRO..
Little difference in Contrast (Canon is better!!!) - but now I am left with NEW PROBLEM!!!
I have, ergo, one Cineform-AVI, which is INTERLACED, and the other Cineform-AVI which is PROGRESSIVE (both 25 fps)...
]Which Preset to choose in PPRO?
I tried with Sony's XDCAM EX 1080 25i preset - but then the Progressive material seems to have lot of flickering... Not to mention that both have YELLOW LINE above in Timeline - meaning it is not the Preset for those files, but it seems to be my best choice (regarding resolution and FPS)!
]Now, HOW TO HANDLE THOSE TWO FILES ON TIMELINE - One 25i, the other 25p?
Do I deinterlace the 25i or do something else with 25p? How? Any Tricks?
What would you do?
And what preset would you use????
Hope you'll be able to help me with this one!:)
V.

Hello again!
If it were me, I would deinterlace the 25i footage and keep the project progressive. But it does really depend on what your final output requires.
Little difference in Contrast (Canon is better!!!)
Try using Premiere's color correction tools (fast color corrector, curves, etc.) for that.
I tried with Sony's XDCAM EX 1080 25i preset - but then
the Progressive material seems to have lot of flickering.
Did you try interlacing the footage (Right click on clip, select "field options", and check "interlace consecutive frames")?

23.98 (24p) PAL in DVDSP?

23.98 (24p) PAL in DVDSP?
quote from the DVDSP manual:
To create a 24 fps MPEG-2 asset, you need to use Compressor (included with DVD Studio Pro) or a third-party encoder that supports encoding 24 fps MPEG-2 assets…
…You can use 24 fps video assets in tracks just like you would use regular 29.97 fps or 25 fps video assets, as long as they match the project’s video standard (NTSC or PAL). You can also combine 24 fps assets with regular video assets within a track, as long as they use the same resolution.

We have tried this with CinemaCraft creating a 23.98p file 720x576 using a custom preset.
When attempting to bring this into a PAL DVDSP project - we are told the asset is NTSC and can't be used.
We contacted CinemaCraft - they tested and got the same result.
Both we and they created a 23.98p NTSC and tried to bring this into a NTSC project as a test - DVDSP stated file was invalid.
CinemaCraft support deduced DVDSP does not support 24p files - which seems contradictory with the text from the manual.
We tried to make a 23.98p or 24p PAL M2V with the standard Apple Compressor (without CinemaCraft) - as soon as we select PAL the frame rate drop down jumps to 25fps and is greyed out.
It would appear Compressor is not capable of creating 24p PAL files.
It also seems DVDSP doesn't support them even if you can make them.
We have a 24p ProRes422 feature and would love to not speed it up, was hoping to 'flag' the stream for 2:2 pulldown in the player - sounded good in theory.
Anyone done that here?

You're actually better off not using CF24. Best would be to shoot 50i on the Z1u and de-interlace then slow from 25p to 24p in post. This works very well.
Next best is probably to use my Standards Conversion www.nattress.com 60i to 24p plugin which does a better job than the CF24 mode, and you don't have to go to the bother of removing pulldown.

MP4 files have audio but not video

Using Premiere Pro CS6, I have no video when importing clips shoot with the new Canon HF G30. The clips are shoot in 1080P @ PF25 (25P). The audio is fine, but there simply is no video. Importing AVCHD clip from the same camera has no problems. Any suggestions as to how I get these clips imported with both video and sound?

Here they are:
MP4:
And the AVCHD:
Remember, I have tried importing both clips in Premiere Pro CS6, and the MP4 clip shows no video. The AVCHD clip does.

1280x720 25p not outputting through Mercury + Blackmagic

So this issue is why I am not really using AE CC 2014 as much as I would like to.
When I make a comp that is 1280 x 720 and a frame rate of 25p it does not show in my broadcast monitor. I have switched on the output for non standard frame sizes set to centred but I get a down size to 576 at 50i rather than an upscale to HD 50i. Is this at all possible and why is 25p not a standard output when it is a preset in the composition chooser? In fact there is no preset for 1280x720 50p which is a telling omission. To get it to work you need to change the default 1280x720 preset in After Effects to 50p for it to show correctly. Now I understand that 1280x720 50p is an industry standard but my workflow (and I think if you look on Vimeo you will find this to be the case) is 1280x720 25p 30p or 24p for output.
This from the compression guidelines on Vimeo's site:
Vimeo recommends uploading with frame rates of 24 (or 23.976), 25, and 30 (or 29.97). If you know the frame rate of your footage, it's best to encode your final video at the same frame rate. However, if your footage exceeds 30 FPS (frames per second), you should encode your video at half that frame rate. For example, if you shot at 60 FPS, you should encode your final video at 30 FPS. If you're uncertain what frame rate you shot at, set your frame rate to either "Current" or 30 FPS. If there is an option for keyframes, choose the same value you used for frame rate. Important: Always choose "constant" frame rate instead of "variable" frame rate.
When I use After Effects CC this is not an issue and a 1280x720 25p timeline gets output as I can select a 720 50p output in video preview settings. Yes it is the old video output system that has now been replaced by Mercury in AE CC2014 but it's much better. I used to always shoot 720 50p as this allowed for great slomo if you needed it but you could output to 25p by dropping it in 25p or 24p timeline. I now have a GH4 which shoots 50p full HD so it's not so much of an issue, but seriously you could not edit a 720 24p timeline and view it at 50p it just look rubbish.
So all I'd like to know is who's fault this is and if a fix would be at all possible. I would hazard a guess that because Blackmagic has no 25p output then the ball is in their court. However since it did work in AECC perfectly well before why can't it work here.
It would be great to hear if other people have this issue.

Make sure you have installed the latest version of the Blackmagic drivers for your device: http://www.blackmagicdesign.com/support
If the problem persists, please post a screenshot of Preferences > Video Preview in After Effects CC 2014.
Also, test whether or not video preview through the Blackmagic device works in Premiere Pro CC 2014.

FCPX: file type question (MP4 or what?)

Hi there,
here's one more.
I was editing some video from Sony A-55 camera and noticed something odd. When stopping in parts of the film where there is movement, a zigzag-edge appears. Now this would be fine in, say, DV. But the footage is supposed to be MP4, 1440x1080 progressive.
When I select a clip (in event browser or timeline) the inspector shows that it is interlaced. Also I have a possibility to change something... to either un-modified, upper-, lower- or progressive. I know what they mean, but if fcpx "thinks" it's interlaced, what should I do?
The camera has two choices when filming: AVCHD and MP4. They aren't comparable, I know... that's what the camera says. The AVCHD (1920x1080) is interlaced and the MP4 (1440x1080) is progressive, again, that's what the specification says. All of my material is MP4.
Should I change the setting in the box to progressive before I edit? Is there anything I can do if the project is practically finished, ie. should change the setting in every clip in timeline?
This is very important because the whole project started in "based on first clip"-mode, so pretty much everything is screwed up setting-wise... so can change project settings afterwards?
Thanks for your help,
Teemu

Here's a screensave to help understand:
this is how it looks originally and like I said, this is supposed to be progressive...
who is wrong, and more importantly, what should I do to have best quality in final version?

I try to resist saying "all" but many, many, many camera manufacturers (all of whom have slightly variant methods of compilining video into formats like AVC/H.264, etc.) usually have their cameras set to shoot 60 frames per second... and since progressive is not supported at 1920x1080 in AVC, the 1080 is always interlaced (if any camera does 1080/60p, the output file is *not* going to be AVCHD, it will be some other format.) Then, that 1080/60i footage is repackaged * in software * to be 30p, 25p, and 24p - and when played at those rates, it will appear to be so. If there is a way for the file format to inform other software how it's supposed to be rendered, somehow that eludes FCPX. [I was looking at some cameras last night and saw that telltale line: "shoots 25p at 60i" ... big tip-off!]
When you import your footage into FCPX and you see interlacing, you can go into your Settings pane (the same as the image you have in your post) and change the Field Dominance Override (most of the time it should be Lower Field first) in order to remove the interlacing. You might want to create your projects with Custom settings and *set* the 25p and have FCPX "conform" the incoming footage to the storyline (that usually eliminates the problem you are describing).
If you are using another application to render out ProRes versions for importing into FCPX, we need to know what you're using! It also helps to know if you are importing your footage via Import from Camera. That's why Tom keeps asking what you are doing to get the footage into FCPX.
