NTSC to PAL conversion - what about audio?

I'm converting an NTSC project to PAL. I'm using JES Deinterlacer to convert my Mpeg 2s to PAL at 25fps. What about my AC3 audio clips? How do convert them from 29.97 to 25fps?

Just to be clear, sound is the same. It does not matter what video standard you are using as audio is independent of the video standard. Just re-use the .ac3s that you have already got.
Note that one second filled with about 29.97 video frames lasts the same time as one second of exactly 25 video frames, and my watch has moved on one second!
P.S. There's one caveat - if you change the length (running-time) of your video for some reason, you would have to adjust the audio to match. This only happens if you are using conversion "cheats" like mapping 29.97fps to 23.98fps progressive, and then going to PAL, for instance.

NTSC to PAL Conversion Process

I've read all the posts that suggest using JES Deinterlacer to convert an NTSC QuickTime file to PAL.
The questions are ...
- Do I then just compress that new PAL file using Compressor's standard MPEG-2 settings?
- Is there anything special I need to set in Compressor (v1.2.1) for PAL?
- What about audio? Can I use my old NTSC AC3 file or should I re-compress the AC3 in A.Pack using the PAL source?
Thanks!
-Bob.

Yes.

No. Compressor just take the video standard from your source movie. When you encode NTSC footage you don't have to tell Compressor nothig about the standard. The same here.
- What about audio? Can I use my old NTSC AC3 file or should I re-compress the AC3 in A.Pack using the PAL source?
Using the original audio from your NTSC movie will give you "most probably" an out of sync issue. Encode the audio using the new PAL movie.
If you cn upgrade to Compressor 2, you'll find the new Standard Conversion features great!
Come back if you find problems!

Pitch Change fix for 24p NTSC to PAL Conversion

Anyone here have a decent tutorial for Audacity or Soundtrack Pro to fix 4% pitch change caused from 24p NTSC to PAL conversion? I don't have Protools. Thanks!
Alexander

In the Project tab of STP (top left pane) there is an Audio PullUp/PullDown menu. You should find the preset you need in there.

Audiobooks are currently a one-time only download. If it didn't download correctly then try the 'report a problem' link from your purchase history : log into your account on your computer's iTunes via Store > View My Account and you should then see a Purchase History section with a 'see all' link to the right of it ; click on that and you should see a list of your purchases ; find that audiobook and use the 'Report a Problem' link.

Any successful NTSC to PAL conversions out there and how?

Hi all. I am using Compressor 2 and have yet to get a good NTSC to PAL conversion with the built in preset. I could use some suggestions.

If you are unhappy with the current results don't use the standard preset. Try one of the other frame control options that offer higher quality but with much longer processing times. Also, make certain that you have the latest Compressor updates, the last update had fixes for NTSC/PAL conversions.
Finally, you might want to try the freeware utiltiy JES Deinterlacer. JES does adaptive deinterlacing, inverse telecine, and NTSC/PAL conversion and many users seem to be happy with its results (and since it is a completely free download you can hardly go wrong).

Converting NTSC to PAL in CS5, the audio is out of sync-too slow. What do I need to adjust?

Hi. I had to purchase a new Sony video camera in USA (NTSC 29.9fps). We are PAL, so most of my holiday movie is PAL 16:9 widescreen. When I imported the clips from the NTSC camera, I converted the clips to PAL 25fps but the audio is out of sync and appears to be too slow. eg. a male voice is high pitched and not quite audible. Is it the 'bit rate' difference causing the problem and if so, how do I change that in CS5? The PAL clips off my old camera are imported as MPG files. The new camera files are MTS. I am not sure if this is important but would appreciate some help. Thanks.

Adobe doesn't have any tools that perform adequate NTSC<=>PAL conversions, in my view. You may be better off creating a separate video for the NTSC stuff, keeping it as NTSC. Your player should be able to handle it fine.

NTSC TO PAL conversion sounds/looks slows

Using Compressor 3.0.5 I made a test. A 4 minute HDV 720p30 clip was exported, reference from FCP. I used the Apple > Other workflows > advanced format conversion > standard def > DV PAL setting to change it from NTSC to PAL. I also made a test conversion using the Nattress Standards conversion plugin.
Questions
1. audio/video sounds/looks slower with the Compressor version than the Nattress plugin test version. Since both are playing at 25fps in Quicktime player, what should I do in the Compressor setting to get good results? How do I correct it?
FYI I imported the Compressor compressed file into DVD SP, made a PAL project, track 16:9 letterbox and it looks o.k., just sounds/looks slow.
Thanks for helping!

I don't have the answer to your question, but...
NTSC DVDs will play back in %99 of PAL set top devices without issues. Computers don't care if the standard is NTSC or PAL. If this is a one-off disc, chances are it will work fine as it is. Check with the recipient.
If you are about to make dozens of discs or even go to replication, you should look into having the master transferred via a dedicated hardware converter such as those from Terranex or Snell & Wilcox.
You will get excellent quality and it will be real time.

PAL to NTSC or NTSC to PAL Conversion in Premiere

Hi Guys,
I have come hat in had to ask the gurus here about format conversion. I have a Lagarith AVI that is PAL, 30 FPS & progressive. If I am encoding that to NTSC, what steps should I be taking?
Thanks!
Howard

you dont have to have hat in hand... nobody is gonna bite your head off.
this is place where users of programs like YOU help each other.
To do that sometimes questions are answered with an eye toward fixing ( educating ? ) a person about the underlying causes of confusion. This means spending a moment to explain things sometimes...rather than just blurting out the obvious and making a poster look for the answer somewhere else.
NTSC is based on the electrical grid of 60 cycles per second... and so half of that is 30 frames per second.
PAL is based on an electrical grid that generates AC current at 50 cycles per second.. so half of THAT is 25 fps.
This has to do with broadcast TV. It has NOTHING to do with what your camera actually shoots, your options with your source material... it ONLY has to do with broadcast TV.
If you live in a country that is PAL ( like the UK ? ) then they broadcast PAL at 25fps.
If you live in a country like the USA then they broadcast at 30 FPS.
What you need to do is determine what country you want to send your product to... broadcast it...or make DVD for local TV's to watch it...
Do you live and work and want to deliver your video in PAL or NTSC ?
Again, this has NOTHING to do with what you shot your video with. It only has to do with what your delivery is.
If your original source material ( video you shot ) is 30 FPS... than it is in line with being NTSC...cause that's what the US and other places using 60 cycle per second electric generators use for their main power grid.
That is what Ann meant by saying it is " already" NTSC ". she was referring to your source material if it is in fact 30 FPS.
What YOU do with that in your editing export etc to accomodate different 'markets' ( pal and ntsc etc ) is up to YOU.... and there are different ways to do that...depending on which way you are going....
For example, interleaved is nice for some broadcast markets ... instead of progressive. It all depends on stuff you want to deliver to. It has nothing to do with what you SHOT it at...or your source material.
Google NTSC and PAL and progressive vs interlaced and you will start to see what is going on...
good luck !

VHS (NTSC and PAL) conversion to DVD

I am trying to figure out an easy way to convert years of old kids videos (VHS in both NTSC and PAL format) to DVD.
I have seen there are combo VHS players (NTSC) with DVD recorder and hard drives. This looks like a lot easier than connecting Canoplus ADVC device.
Any advice welcome,
thanks

Welcome to Apple Discussions
If you have a digital camcorder you can do what I do. I use a Sony DV camcorder as a pass-through to convert video tape (VHS, Beta & video 8) via FireWire into iMovie.

NTSC to PAL conversion lost chapter markers

I have a home movie in NTSC that I wish to send to England on a DVD and so want to convert to PAL. Following the instructions in Help, I created a PAL version in Quicktime. iDVD can open this but the chapter markers seem to have disappeared and I can't open it in iMovie to reset the markers - presumably QT doesn't support markers.
Pete

Just send the NTSC disc to England. About 99.9% of the DVD players play NTSC discs (and about 99% of the TVs handle it, too).
(This is for home video DVDs; we're not talking commercial/Hollywood discs here that have region codes).

Ntsc to pal conversion

what is the best settings in COMPRESSOR to convert a DV file from NTSC to PAL (that will not take 4 days to convert one hour....)

If you think of your time as worth, oh $50/hr then all you need to do is save 2hrs and the software has paid for itself. Any speed increases after that are pure profit.
If your your time has no monetary value, then I can appreciate your desire to use compressor for this.
Hopefully someone will chime in with settings.
Good luck.

Ntsc to pal conversions with small file sizes

I'm trying to convert a file from NTSC to PAL, which I have done successfully in the past. However, the file needs to be under 200MB (the video is 3.40) and I can not seem to get it any lower than 346 MB using the dv-pal setting and everything as low as possible and the sound set to mono. Any suggestions?
Thanks,
Christy

DV PAL is a set data rate - 3.56 MB/s when run at 25 fps.
If you want a smaller file size you have two choices -
1. convert the file to another codec that allows for smaller frame sizes, slower frame rates and increased intra and inter frame compression.
2. If it must be DV/PAL, cut the length of the video to reach your 200mb limit.
Of course there is the third choice of simply giving them the larger file because that's what an un-compromised DV/PAL version of the file will be.

If I get the Apple Universal Dock , what cable do I then need to get video from the dock to my HDTV . What about audio ?

If I get the Apple Universal Dock , what cable do I then need to get video to my HDTV ? What about the audio portion ?

OK, so that part is correct. Then, do I just hookup and it automatically goes onto my computer? What will capture it, or will it simply show on my desktop and I need to open it with...what?

TIP: 24p ntsc to PAL conversion

Many thanks to Graeme Nattress for this solution.
Our project was a 90-minute doc edited in 24p ntsc. We needed to create a PAL version by transcoding in software. If we simply placed the ntsc version in a PAL sequence, the frame rate change resulted in blurry motion and repeated frames, giving the motion a jerky look.
I had been trying to use the Nattress standards conversion plugins with no success. However, Graeme was kind enough to recommend the following workflow:
1. Create a reference movie of the original sellf-contained movie of the ntsc version
2. Conform the 24p clip to 25 fps in Cinema Tools. This took about 1 second. The resulting clip was 4% shorter (about 4 minutes) and the audio was automatically speeded up to match.
3. I now placed the 25 fps ntsc clip into a PAL sequence and scaled it up to 120% to fill the PAL frame. I exported my mpeg for DVD using compressor, which took only about 6 hours to encode on a dual 1.8 G5, a perfectly acceptable ratio of about 4:1. The result was that all of our original 24P frames were intact, with no conversion, interpolation, extra frames, blurring, etc. The quality was much better than any other workflow I had tested, and it saved us lots of rendering and exporting time.
Thanks again Graeme!
Max Average

Yes, definitely the way to do it.
Even in the NTSC world, low-budget filmmakers have been doing the reverse for years - shooting PAL because of the ease of conversion from 25fps video to a 24fps film print - a 4% slow-down in this case. The extra 96 lines of vertical resolution is especially beneficial in this workflow too!
Good to see you NTSC guys more with PAL!

NTSC to PAL conversion help

I am editing an NTSC program in FCPx (Project settings are 720p HD, 920x720, 29.97fps; Render format Apple ProRes 422 (HQ) )
In Compressor I am trying to ocnvert the program to PAL using the *H.264 codec (.mov). There is no "PAL" setting option for this format, but I have set the frame rate to 25fps, however my program duration is being affected, with the 30min episode coming out at around 34mins, obviously slowing down during the frame rate conversion. What can I do to prevent this?
(*Ideally I want to create a MXF format render, but Compressor seems unable to do this?)
Help much appreciated ASAP as I have a deadline of today!
thanks,
Geoff

Even if you can't make MXF, you should probably still adhere to the rest of the specs, namely MPEG-2 encoding at 8MBps.
For the framerate conversion, make sure Frame Controls are On, and set length to "100% of original", and use the highest-quality frame conversion. It is very slow, but unless there are very fast-moving objects, it will produce excellent quality. Be sure target framerate is set to 25fps (it should be if you use any PAL preset.)
The company to which Russ H linked seem to make an MXF export plugin for for FCP and Compressor, though perhaps not directly for FCP-X, but I have no experience with them.
