PAL to NTSC & Audio Sync

Thanks in advance for your help.
I receiveda an audio file that was originally in sync to a PAL master and I need to sync it to the NTSC video master. The audio come out short when dragging it into the NTSC timeline and speeding it up 4% gets it closer but it is still out of sync (drifts)
How would you go about properly matching/resyncing the audio to the NTSC video? Either in FCP or ProTools.
Thank you.

PAL is 25 fps, while NTSC is 30 fps (if you matherial originated in video, not film, that is!). Please calculate the percentage more crefully. 4% is just not enough. Try 20.83% instead/
Sorry if I'm wrong but we never use NTSC in Europe.

PAL to NTSC Audio Sync Issues

Hi All,
I've searched through the forums and have found some similar issues but nothing exactly like this.
I am editing a music concert that was shot in PAL. The audio was also recorded separately and has been edited and mixed in ProTools.
When I take the exported audio and put it into my PAL timeline, it drifts out of sync with the video as expected. My questions are:
1) How should the audio be exported to match up to my PAL timeline?
2) When we convert to NTSC, I will use the Nattress filters for video, but what do i need to be concerned about re: the audio?
Thanks big time,
Jason

Here's what I don't understand - some guys captured this concert in two ways - a PAL camera (and associated audio) and then some sort of audio recording, a believe a DAT.
They gave us PAL tapes which we have captured, and then ProTools audio files. Theoretically everything should match up at this point (the audio from the cameras and the audio from the recorder should be the same, right?)...
Why would it be that after changing the MIXES (but not shortening or lengthening the audio), exporting from ProTools, and then laying them into the FCP track (syncing up to the first beat of a song, etc), they audio drifts? Not bad, about 1 1/2 seconds in 6 1/2 min of footage.. but nonetheless, this is a HUGE pain.
Given this is a music DVD and the artist is a major musical stickler, changing the audio has a ZERO percent chance of being acceptable...
Thanks again for your help -

PAL to NTSC audio conversion?

I have converted my PAL video to NTSC but the audio was mixed separately and so it's still set at 25fps and hence becomes out of sync when I lay it against the video track.
So how do I convert the separate audio.aiff files from 25fps to 30fps?
Thx
Kevin

audio doesn't really have a frame rate. I understand from reading other posts that fcp (and/or) quicktime may associate a frame rate with an audio file, but there should be a way to remove this association. Maybe try running the audio file thru compressor? If you want to send me a short section of the audio file, I'll see what I can do. My email is in my profile.
I seem to remember there being something about importing the audio file into a new fcp project with an default easy setup with the correct frame rate. Not sure about this.

PAL to NTSC - losing audio sync

hi
i have been using nattress standards conversion to convert a 6min DV PAL Video to NTSC.
it works fine, besides the audio which went out of sync.
i have tried re-converting to original video to NTSC with the "sync to external audio" but the results are the same.
am i doing something wrong or is it always like that ?
is there a way to do it (in compressor ???) without losing to sync ?
thanx
nir

One of the reasons I can't use the Nattress system is because I can't get the audio to sync - despite using "sync to external audio" as you found.
As Silal pointed out, a great way (high quality / hassle-free) to convert PAL to NTSC (although it takes a lot longer than Nattress) is the Hanumang method listed on Silal's link.

NTSC audio to PAL ?

I had an NTSC video converted to PAL, but I just realized that there was a slight glitch in the original audio. I have a short timeframe so sending the video back out isn't an option. I was hoping that I could output the audio seperately, but when I do the audio slowly drifts out of sync. I'm guessing it's because of the different frame-rates and how the video was converted to PAL. So basically I'm wondering if there's a setting in FCP or compressor to convert the audio to PAL or if I need to manually slow down the 29.97fps NTSC sound by a certain percentage to get it to match up with the 25fps PAL video, similar to slowing down sound to match up with telecined film. Any help is appreciated.

Export the audio as an AIFF file from FCP. You can then convert it in Compressor to Dolby ac3.
The audio file is neither PAL nor NTSC. If it was 32' 26" long, for example in one format it must be the same in the other.
You should check that both your NTSC and PAL video files have exactly the same duration, otherwise the standards conversion was not done correctly.

PAL subclip out of sync when placed on NTSC timeline?

The job: 700 adverts from PAL and NTSC from 40 U-Matics - choose 300 and make an NTSC DVD compilation.
I converted the tapes to DVCPRO50.
I created subclips for each ad on each tape.
I created a new NTSC DV timeline and placed the subclips on the timeline.
(I planned to use Nattress Standards Conversion to convert the PAL subclips to NTSC).
I noticed that the PAL clips' audio cut out early. I displayed the audio waveforms for the clip - the waveform wasn't cut off - it was in sync with the end of the clip, Final cut was playing the audio late and cutting it off to match the video.
I exported the edit (to check if there was a delay in the playback of the audio on my machine), the actual output had the audio out of sync too.
When I exported the subclip as a QuickTime movie and reimported it, placed this new PAL movie on the NTSC timeline, the cut off didn't happen.
Surely the subclip and the exported QuickTime movie should behave the same on the same timeline.
Has anyone else had this problem?
Is this a known bug in Final Cut?

How was this clip imported? If it was captured/ingested, did you make sure that the sample rate of the capture settings matched the sample rate of your audio? Normally FCE will give you a warning if they don't match, but it can't hurt to make sure.

Transfer PAL to NTSC and extract audio: Best Place in L.A.

I have a little record company. I'm going to release a video of a concert as a DVD and will ALSO release a CD of the same concert. I want to extract audio from the PAL (for the CD)at best quality for remastering.
I also want to Convert the PAL to NTSC so I can edit it in FCP. (I assume that's the best quality Video I can get under the circumstances. Is that so? Is there a better way? It's music, so it HAS TO BE in sync)
I will do the editing for the DVD master, and my mastering guy will deal with the music for the CD.
1. Can anyone suggest the best place in L.A. to do these transfers?
2. Can anyone suggest the best place in L.A. to author and replicate the DVDs?

Laurie,
I've put the word out to the LA contingent of FCP elitists about your question. Hopefully one of them will respond.
If you decide to go through a software based conversion, there is a thread over in the FCP forum that will be useful to read.

PAL to NTSC simple solution

I realise there are probably many threads discussing this topic but I have just finished converting a 25fps movie to 23.98fps i.e PAL to NTSC and found after a lot of trial and error and trying an array of recommended methods that the simplest and best result is this:
1. Export your movie as a self contained clip from FCP and the audio as an .aiff
2. Open the clip in Cinema Tools and conform it from 25fps to 23.98fps
3. Open a new project in FCP and import the clip and the .aiff
4. Double click the clip within the Browser and adjust its speed to 104.165 with frame blending off which will adjust the clips lenght to the same exact lenght of the original PAL file and the .aiff
5. Put the video clip onto a time line with the same settings as the clip along with the .aiff audio
This final clip will now have a frame rate of 23.98 and the exact lenght of the original PAL clip with the original audio in sync.
For some peculiar reason the running time of the movie shown in the timeline is not the same as that shown in the browser but when you export it for dvd using compressor the resulting m2v is the correct lenght. You must also export the audio from the new timeline to go on the dvd as either another .aiff or a dolby digital.
There are some odd things going on with the stated running times of everything but the end result is correct.

I'm with Michael on this.
I use Graeme Natress's Standards Converter for this within FCP if it is a small project and use Compressor feeding Qmaster clusters for something more lengthy.
Clusters make a huge difference in the performance of Compressor. I have Clusters set up on machines running 10.6.8, 10.7.5 and 10.8.3 so I know it works on the range of current OSX versions.
Digital Rebellion has a good write-up on how to set up Qmaster.
Good luck,

So frustrating that nobody knows why. Audio Sync issue.

I have an imovie project of old family footage that was ported over from VHS through a sony dcr pc120e mini dv cam straight through to intel imac via firewire. The imovie project is flawless and the sound is perfectly in sync. ive exported to idvd and when finished the audio is out of sync on the final disk. Now i have been reading about this issue and see that people blame idvd8 but it happens when i make a dvd with my imovie project using toast titanium 9 too. Surely if it plays perfectly as an imovie project there must be a way of transferring to dvd without audio sync issues. If anyone knows a solution or piece of software that will remedy this please please let me know as i have wasted about 12 dvds in various experiments.

thanks for answering some of my Qs ...
there's one thing, I do suspect, which was a 'source' for sync-weirdness for years.. which is the AUDIO connected to some video.
you told us, video is 25fps, and audio is included 16bit (which is good...)
I assume, adding some NON-conform audio could cause trouble... (as a 12bit audio would cause outofsynciness) .. we do know very little about, how iM08 handles audio+video internally, we 'Silverbacks' had long discussions about really weird side effects as a 'zooming' of dvfiles on export etc. I wouldn't be surprised, if adding some non-iTS, non-48kHz-aiff, non-whatever... causes such an effect.
so, please answer my audio Q from above: source, format, bitrate...?
and just for curiosity: how long is your project in total? hh:min:sec?
==edit==
pops into mind: in iM vers3, there was some 'bug', concerning PAL wrong audio and NTSC good audio ... wow < scratching bald head > .. try to contact some wiseguy with better memory..

Audio Sync Issues Final Cut Express 3.0

I'm running an older version of FCE 3.0 I am having sync issues (audio slower than the video) when importing from my camera (small Panasonic handycam).
Does anyone have a solution?
thanks

Sync problems are often caused by using the wrong Easy Setup.
Cameras can shoot audio in either 12bit or 16bit mode.
The standard Easy Setup of "DV - PAL" (or NTSC) is for 16bit audio.
If you shoot 12bit audio your easy setup must contain "32kHz".

PAL to NTSC Text issues

Question about FPS and Audio Sync...

If I record a program from a broadcast HD source and it's transmitted at 24 FPS and I edit/export it in .wmv format at 30 FPS is it possible that it's causing any audio sync issues I might be having? Should I be exporting it at 24 FPS?

Well, you're not likely to be able to get 24p video to work right in Premiere Elements regardless.
That said, no, the difference in frame rate alone will not cause your audio to go out of sync.
What you'll more likely see is poor blend of frames in your video. It might look jaggy or fuzzy on output.
That is IF it works at all. Premiere Elements technically only supports 25 fps PAL and 29.97 fps NTSC.

Having trouble with Audio Sync in FCExpress

Hello, everyone...a question for the board.
I recently acquired a new iMac with Final Cut Express...planning to try some video editing at home.
I haven't been successful with the proper configuration for captured video, however...using a Sony TRV-900 as my source, video feeding in via firewire 800 (I bought a 400/800 adapter to make it work), and ingesting using NTSC Basic...however, my audio is still not in sync with the video--the video is always ahead, and it jumps further ahead the more I ingest.
Is there some configuration I need to use so that the audio syncs correctly? Is it, as I suspect, a drop-frame issue that I haven't set up correctly?
Any help you could throw my way would be very much appreciated.

I realize that most DV cameras will record in 32 and 48 sampling rates. What I'm trying to get you to do is see what you've ALREADY recorded.
Open one of the captured clips in QuickTime, then hit Command j to see the movie properties. Or in FCP, right-click on a captured clip and choose Item Properties to see what audio you are trying to capture. Once you know that, create a Sequence with those settings, then capture any remaining footage with those settings. If needed, recapture any footage that was previously captured using the wrong settings.

Audio Sync Problem after transitions/filters applied to timeline in FCP

I have Final Cut Pro 5.1.2 on a MAC Pro. I installed 2 Maxtor SATA II 200gig drives and created a striped RAID. I want to be clear about audio sync issues. I have my easy setup/properties....all those settings set to DV NTSC and I am monitoring out from my DV Deck via firewire, not the audio from the computer.
After capturing the clip(s) I assemble them onto the timeline, add a few transitions or filters. The audio shifts off a lot. More everytime I add or do more with the clip. After rendering more, the audio shifts more. All scratch disks, rendered clips points to the Video Drive (striped RAID) I've setup. I'm not new to video editing but new to a MAC. Yes, I am a PC guy. I work with Premiere Pro 1.5. I am pleased so far making the switch, just need to fix this audio issue.
All properties of the audio clip are correct, DV NTSC properties - 48K etc. This particular capture I made with 2 channel mono clips instead of a single DV stereo stream, simply because I have a split audio on the production tape and would like to take advantage of working with two seperate mono audio files. When I trim, I make sure the audio stays with the video but it appears that when I do trim, add a transition or filter, that's when the audio goes out of sync. No indication with a ("- #")on the icon. The clips which I captured are less than a minute long. Used for testing in these new learning stages.
Questions:
1. I created a striped RAID with the 2 Maxtor drives, I used MAC OS Extended (Journaled) with 256k Raid Block size. Is this correct?
2. Would the audio captured in 2 channel mono affect the sync? (assuming you don't shift it manually on the timeline)
3. What other MAC settings should I do to the system that will result in better preformances?
4. What settings should I set in FCP for better performance results?
MAC Pro Mac OS X (10.4.8) FCP Studio
MAC Pro Mac OS X (10.4.8) FCP Studio
MAC Pro Mac OS X (10.4.8) FCP Studio

hi vcp
welcome to the forum, glad you made the switch ... you won't be sorry (although you might be wondering at the moment!)
1. nothing wring with that
2. no
3. just don't install 3rd party crap you don't need ... and don't install any anti-vrus software
4. no special settings required
what camera did you capture from? did you capture with FCP?
cheers

Exported .mp4 and FlipFactory audio sync problems

I work for a television station, and we use FlipFactory to convert everything before going to our playout server.
When using the H.264 preset in CS5.5, everything works fine.
When using the same preset in CS6, after going through FlipFactory, the audio sync starts to drift. By the end of a 30 minute program, the audio is way out of sync. If I play the file (after CS6 export, before FlipFactory) in WMP, VLC, MPC, the audio stays in sync.
Using the H.264 BluRay preset, everything is fine (in both CS5.5 and CS6), but obviously, the file size is larger due to the container.
I understand that most will say this is a FlipFactory issue since the file plays back fine before FF does it's thing, but something must have changed from CS5.5 to CS6 regarding the H.264 encoder, as CS5.5's files go through FF just fine.
Any help would be appreciated.

Did somewhat of what you asked. I exported the same show in CS6, one using the H.264 preset, one using the H.264 BluRay preset. The H.264 preset one drifts out of sync after FlipFactory, the other stays in sync.
Here are the media info specs for each file (I did use different bitrates on the two, but that shouldn't cause an issue):
