Audio levels change depending on dvd player

I have exported a 30 minute documentary from IMovie '11 to iDVD and burned it to disc. When I play this on my own dvd player and televison (standard definition) the sound levels are fine. But when the dvd was played on a friend's dvd player connected to a flat screen tv, the sound levels varied considerably. Is there a way to make sure that the DVD plays on all player?. Should I create one iMovie in the HD/widescreen format and export to iDVD and burn that version so that I have one version for SD and one for HD? Can someone explain what causes this variations?

Thanks for the comments. I checked the cables and they are correct.
If I put an earlier DVD into the same player, it plays fine. It's only the DVD to which I added additional audio that the DVD player won't play correctly. In other words, the audio in the tracks plays fine, but the audio in the menus doesn't play on the DVD player, but plays fine when using a computer.
I don't want to adjust the DVD player settings, because I want the audio to be present on all setups.
For the audio, it's stereo. I export it as an AIF from FCP and then run that through either APack or Compressor2, to turn it to an AC3.
If it were a DVD Player issue, then an earlier DVD with the same menu audio (that now won't play) shouldn't play, but it plays fine. It's only when I add new audio to the tracks that the DVD player stops playing the old menu audio.

Audio doesn't play in DVD player

Hello,
First post here, so be gentle.
When I burn a DVD, there is no sound when I play it on my dvd player. It plays fine when played on my Mac.
Here is what is going on:
1. capture HD video in imovie 06.
2. add chapters, no external audio or photos
3. export to idvd
4. check video in idvd, all looks good, includes audio
5. burn dvd
6. when burn is complete, play in DVD player
results:
No sound when playing video.
I am not sure where to go next, I will try another DVD player this evening. When creating a DVD with the exact same setup but not HD content, everything worked fine.
Any Ideas?
Thanks
Bill

If it plays OK in your Mac, iDVD 'has done its thing'.
Not all set top like writable media - this might be your problem.
More likely, your problem involves a high level of burn errors resulting from low quality media and/or a high burn speed. Instead of going directly from iDVD to writable media, create a disk image file (an option under FILE). Use Apple's DVD Player to verify the mounted (by double-clicking on the disk image icon), then use Apple's Disk Utility or Roxio's Toast to burn the disk image to writable media. Use good quality media (Maxell or Verbatim) and burn at a low speed (4x or slower).

Audio Level Change to and from progr

When I get into even a simple program that i made that didnt go full screen my media player music (WMP ) quieted even though there is now visable change in any audio, also and most importantly is when I load up WC3 or WoW my volume gets lowered on the media player and once again no volume controls change so there is no visable change, I've also had times were there was no sound coming from the player or game, unless I minimised the program and restarted play back in some way but then right when i get back into the game it quits. Sound Blaster Adigy SE?even this simple program that i made changes my audio level soundhttp://thesite.mine.nu:8080/elipse%20test.exeMessage Edited by CTS_AE on 04-20-20072:02 AM

Just to back up Michael. The native sample rate for video is 48khz. To work at anything other than that is to ask for problems.

Apple's DVD Player: audio in-sync. External DVD Player: audio out of sync

I exported my Sequence from FCP to QT, used compressor to make m2v and ac3 (Dolby) files, then used DVD SP to burn a DVD.
When I play the DVD on my Mac Pro using Apple's DVD Player, MPEG Streamclip or VLC, the audio is in sync with respect to the images, FCP's Canvas and FCP's QT export.
But when I play the DVD using any of three different external DVD players, the audio momentarily drifts out of sync by 30 to 40 frames, near the end of my 30-minute program, but is back in sync after about a minute, when the shot at hand ends and the next shot begins.
More specifically, it's as if the video lags by about 30 to 40 frames, but there is no stuttering or other obvious visual sign that this is happening.
Why would Apple's DVD Player, MPEG Streamclip or VLC play the audio in sync while these external DVD Players play it out of sync?
I should add that in order to verify that the TVs to which the external DVD players are attached are not the source of the problem, I monitored the audio using headphones connected directly to the audio outputs of the DVD Players as well as connected to the headphone jacks of the TVs, and there was no difference, i.e. in both cases, the audio drifts out of sync momentarily, as I describe above.
I can only think that DVD SP is muxing the m2v and ac3 file in such a way that software DVD players can demux it without difficulty, but hardware DVD players cannot.
Does anyone know how to fix this problem?
Thanks.

Please tell us what was wrong.

HT4072 Can I play audio from movies in the DVD player using iTunes or Airplay?

I would like to play audio from movies in the MacBook DVD player using iTunes or Airplay? Is this possible?

Is it important that the music come from a video, or are you just looking to listen to music in the background, while doing something else. If the later, you can certainly play music from the Music App, Pandora, or iHeart Radio, etc., and with the music playing, tap your home button to go to your home page and open anything else you want and the music will continue.
I don't have any videos to try out right now, but you try the same thing out and if the music continues, it works. If it doesn't, it doesn't.

Random Audio Levels Change Exporting STP to Aiff Master

I've been mixing a feature film scene by scene (STP can't seem to handle a full feature mix at once due to memory problems) and generally pleased. However, I've noticed on two out of 10 scenes mixed so far, when I exported the aiff file as a master mix, audio levels on various clips (not all) drop considerably in the mixed file. Even clips in the same track lose audio level in places in the mix, seemingly randomly. It's very weird. Then, when I listen again in STP the levels have been mysteriously dropped as well. NOT the volume slider bar. It stays the same. No change in gain. All LOOKS as it was before exporting but the drops are there. It's as if the exporting process has done something to the STP timeline levels without visually changing anything. If I change the layout screens or play around with the submix locations, all returns to normal in STP. But after I tried exporting again, the same problem happens.
I couldn't find any other forum help with this. Some people suggested 'Render to Action' or 'Flatten Audible Actions' for a similar problem someone else posted, but those options are ghosted out on my multi-track project.
I tried deleting all .plist files related to audio, soundtrack and final cut studio (not easy to find, may have missed something). And this problem doesn't exist on some other scenes using the same process which worked fine.... so it's extremely odd.
I am using minimum filtration, just a limiter with -4.5db and 3db of gain on one track. All dialogue going to a submix and all fx to another. There are only 4 tracks of audio in the mix in question.
I 'analysed' and 'fixed' all phase issues in clips. No change.
The original recordings are .wav files from a Zoom H4N set at 44.1 hz, but that's the same in all scenes, so not sure why only two would make a problem. (the project itself is set to 48hz)
I'm fairly experienced in FCP Studio but getting a bit loony over this one, so hope you can offer some help. Please don't suggest using other software like Pro Tools for this mix. It has been working fine and I'm happy with 8 scenes. There must be something simple going on with the 2 odd ones.

I may have found a clue, but still don't know how to fix it. The file from FCP to STP was a stereo file with mic A on left and mic B on right (used a Zoom H4N). I split the file in STP into two mono files and separated the tracks. So actor A is on track 1 and Actor B on 2. All levels fine. I checkerboarded the tracks so there wasn't a lot of overlap. So far so good. Somehow, STP seems to be reading only Track 1 when it does the export; the level drop I'm hearing seems to be Actor B appearing on Actor A's lavalier, even though that data has (supposedly?) been chopped for the checkerboarding. Is this clear? IOW, even though the timeline shows clearly distinct and clearly audible separate mono tracks 1 and 2, the export mix isn't reading it that way and ignores my separation of stereo to 2 mono tracks, preferring to read from only one of the stereo tracks (or possibly only Track 1, but not throughout the track, only where the checkerboarding has occured). And then it somehow 'remembers' the export when it re-opens the project until I make almost any adjustment in STP and it magically returns to normal. Help!!

Audio levels changing in mix

I spend a lot of time getting my audio mix right and ensuring that nothing goes above 0db (red line). After playing back the project time and time again and seeing no issues with the levels going above zero, today I open the project and now levels are guess what, going above zero! Why is this? What can cause the levels to change? The levels I have set on my clips are where they were yesterday so why are they now showing over 0dbs?

For the future: You may want to use the "Dynamics" effect for the master track with limiter set to 0dB and adjusted by compressor. Then it will take care nothing goes over 0dB no matter what.

Changing region on DVD player

Hi, I am trying to watch a PAL dvd and I know there is a way to change the region but I can't figure it out, can some one plaese help me!!

Just wondering how Apple (and probably every other computer manufacturer) managed to get that past the movie studio lawyers.
Apple wouldn't want to hard-code the region because it would mean different drives for computers headed for different parts of the world: so at least one change is necessary, from the default region to the user's region. Since there would probably be finger trouble if only one change was allowed (which Apple would have to sort out under guarantee) five is a reasonable compromise. Anyway, it's very easy to buy ordinary DVD players which can be fiddled to all regions, so Apple are actually being tougher on the subject than many other, non-computer, manufacturers.

Unexplained audio level changes

I keep running into a very strange problem. After I've put a sequence together, and done an audio mix (keyframing/rubberbanding audio tracks in FCP), certain pieces of music will be too loud during playback, even though I have them turned down low, or even all the way down. If I stop the playback and start it again from the same spot, or even back it up a few seconds, it plays back correctly.
It seems to do this only with music tracks. I've tried trashing render files, replacing the original files, and I repair my permissions and trash prefs on a regular basis.
Any suggestions?

Try this...
In your user prefs, reduce the quality of the audio playback to "medium" or "low" and see if it helps. Using a "low" setting drastically reduces the processor load on your Mac during playback.
The audio quality won't be affected to any degree that will bother you for any listening purpose except serious review for post-production done through a "reference" monitor system of speakers. In my opinion, you should be doing that work outside of FCP in a dedicated audio editor anyway. So practically speaking, changing the playback quality setting shouldn't matter much to you in most cases.
So try setting the audio playback quality to "low" and see what happens.
Another question: are all your audio tracks 16-bit 48Khz sample rate, or are some of them different, which means they need to be rendered before playback?
That could affect real-time playback, too.

Automated audio level changes in PP6 now possible on a clip by clip basis?

Anyone know if PPro 6 now enables audio automation to be written on a clip basis rather than on the track? This was the one key feature missing for me when attempting to move from FCP7. I couldn't get my head around having the entire mix rendered useless by inserting a clip at the front of the edit .... waiting for this one - please tell me it's been done!
Best, Ken.

Jim Simon wrote:
Using keyframes is automating volume.
Well...in this context, "automating volume" refers to using the Touch, Latch and Write options of the audio mixer. If you set the keyframes yourself, that's more of a "manual" adjustment.
Well then, let's extrapolate from your statement. The instant that you start moving the "Automation Fader," you have made a manual adjustment.
There's no way to get to "automation" without doing some work, "manually."
The "real" automation is in the playback, irrespective of the method you used to get there.
(BTW, I think that rippling track automation is a damn good idea, and it should have always been there.)

My iPhone automatically changes the audio level to max/zero

Hi all. I have a problem with my iPhone audio level. When I'm listening to music with my head phones on, my iPhone sometimes changes the audio level max or zero all by itself. When I try to decrease/increase the sound, it continues to increase/decrease until sound reaches to the max/zero. Restarting the iPhone stops the audio level change. But this does not solve problem once and for all. It happens time to time, but it is becoming somewhat irritating.
Anyone have a solution for this? I've checked the internet, but couldn't find anyone have this problem. I guess I'm the only one who has this problem. Thanks in advance.
BTW, my iPhone is 6 plus & its iOS version is 8.1.3 (12B446). Although I has been happening since I bought it in December

I wanted to update this post. I realised a something new with the issue and found a way that I can temporarily solve it without restarting the iPhone. Right before it happens, an orange blinking light appears on the empty (white) side of the sound level at the music player. I marked that area on the photo below, although I couldn't managed to capture that orange blinking light. If I change the sound level via buttons, sound goes to max or min (depending on my button choice). Unplugging and re-plugging headphones don't affect this. After re-plugging, blinking continues. But if I unplug my headphone, then close the music player from double tapping the home button & restarting the music player, turns it it to normal. Even my sound level stays the same, at the level I configured before this issue starts happening.
A remainder, this issue only happens after I start listening to music with my headphones. Same thing with speaker never happened. I hope this message make you all understand my issue better. I also hope that there is a solution

Level change when adding audio keyframes

Hi all,
I've been in Avid Land for the last few months and just came back and noticed something that was getting on my nerves when I left (I don't recall seeing this before FCP 6). When I add keyframes to my audio levels with the pen tool, I get a keyframe, but at the same time, it lowers my level as if I had added a keyframe and then dragged it down. As far as I can tell it does this every time.
Does anyone know what this is about?
Thanks,
Matt

I was having this problem, so just before I composed this reply I did some tests. It could well be 'sloppy mouse work' but I don't think so. This time the audio level went up by 1 db but before it was dropping by 1 db when adding a keyframe. During the test, no matter how accurate I was the audio level changed when adding a keyframe. The track I was working on was enlarge somewhat and the problem didn't happen on standard sized tracks. I feel that this has to be some sort of bug.
I have always found FCP a little bit on the 'accurate' side. You have to be very precise when clicking on items otherwise you will miss. Some buttons are way too small and I think Apple could improve the FCP workflow by enlarging some buttons and allowing more space around clickable items.
A good example of this is the 3 way colour corrector. The left and right buttons for blacks/mids/whites are very hard to hit and I quite often hit the maximum by mistake.
I have worked on many non-linear systems and FCP is the only one where mouse accuracy is so important.
I am, to some extent used to this now and I suppose it is a minor inconvenience in comparison to the benefits of using FCP but, in the interests of improvement and ease of use it would be good if Apple could take this onboard.
Weenie.

DVD Player 5.6 and OS 10.8.3

I purchased an LG DVD writer GP60NS50 to go with my MacBook Pro 15" Retina which has no internal DVD player.
When I put in a purchased DVD movie, DVD Player 5.6 starts up and plays the previews, but then it either jams when playing the FBI warning, or it will not let me choose to Play Movie. Once the menu background plays thru its music, DVD Player jams, and I have to force quit.
I can rip the movie to the hard drive, and then DVD Player lets me choose Play Movie, and the movie starts playing.
SO, why does DVD Player jam up on playing a movie from the DVD player? LG says there is no software update on this model, and it is Mac compatible.
I have re-loaded OX 10.8.3 with no change on DVD Player.

Thanks.
The DVD Player problem solver has no problem listed that covers this.
I have opened my (invisible) User Library and deleted the DVD Player preferences.
It didn't change anything.
I have region code 1 (US and Canada) chosen for playing DVD's.
I tried opening a movie with VLC. VLC quit.
I tried using Hand Brake to choose the movie. It quit too.
Playing the movie The Girl Who Kicked the Hornet's Nest jams up 5 seconds into a 7 second FBI warning.
Playing the movie The DaVinci Code plays all the previews and plays the 66 seconds of audio with the Play Movie choice on the screen. Clicking on anything gives the "Not Allowed" alert. Once the 66 seconds of audio is supposed to repeat, DVD Player jams up and I have to Force Quit.
I was able to rip both movies to the hard drive, and they both play fine with DVD Player from the hard drive.

Unable to Connect T7900 To DVD Player

i had bought philips DVP 550 DVD Player which supports 7.1 channel system and i had also bought a Creative T7900. But i m not able to connect the T7900's Stereophonic Pins to the DVD Player, as there are 8 Audio RCA pins to the DVD Player as (Front left&Right, Surround left& right, centre, subwoofer, rear left&right), i m having a problem to connect the streophonic to the RCA pins so please give me a suggestion about this. Manish

You just need to follow Jason-CL's thread for 5.1 and use an extra 3.5mm jack to rca lead for the rear surround.

MacBook as upconverting DVD player

Does a MacBook - connected directly to a plasma HDTV - offer any advantage over a regular DVD player?
I couldn't find much on this topic so I tested it myself and found my MacBook is an excellent DVD player. I don't have an upconverting DVD player to compare to, but I can say the MacBook (FrontRow player in Leopard) is far superior to my progressive scan Toshiba SD-3750 DVD player (component connections), which isn't bad. I suspect the direct digital connection to my Panasonic 50" plasma accounts for most of the gain - no D to A to D conversions. Not sure whether the Mac or the panny does the upconversion, but the result is very good.
Now, I don't know if I want to hook up my laptop every time I rent a DVD, but it'll be hard to watch the old Toshiba player now that I've seen the light.

I played on DVD from my MacBook to my LCD and it did work great. However, the downside of doing so is just not worth it in my opinion.
1. Cord problem. Necessary to hookup cords to TV to do so.
2. Perhaps unsafe layouts as to where to place MacBook. Due to cord length, I had to balance my MacBook on a chair and hope is stayed there.
3. Wear and tear on DVD player in laptop. From reading several posts on this site, there seems to be a problem of DVD malfunctions due to perhaps excessive play.
4. Economics, there are several up-conversion DVD players on the market for well less than $100. I recently bought one at Costco for about $40 and it seems to do a great job and plays everything I throw at it including stuff I burn, some of which, my MacBook DVD player won't play.
5. Ease of use in having a DVD player ready to go at a moments notice without going through the hoops of connecting a MacBook.
6. And the biggest reason, I don't have to worry about a DVD getting stuck in my MacBook. From time to time, I had DVD's and CD's get stuck in desktop optical drives. At least when it happens there, they have a tiny hole that will eject the tray manually when poked with a paperclip.
1. I use my MacBook's "extension" cord left in place near the TV, and use only the brick for most day-to-day stuff. I also have a DVI-HDMI cable just for this purpose, with the Apple adapter, also in place. Worst thing is I have to borrow the audio cables from the regular DVD player. Going to optical cables soon, so even this will be easy.
2. Yes, perching on anything isn't good. I have a handy spot on the floor that's out of the way.
3. My biggest qualm. I don't use the drive for much else and frankly don't watch many movies, so I'm not too worried. But agreed it's not a good permanent installation. I guess a cheap external DVD drive is an option. More cables though!
4. I've been wondering how good a job they do, whether they're a scam or not. Do the cheap ones really beat an older progressive-scan DVD player? Maybe with the HDMI (all digital) connection they do. Also considering a PS3, and that's what got me thinking in the first place. Seems like PS3 = AppleTV+Blu-Ray player+gaming.
5. No question, but see #1. I only started doing this to watch Lost in HD streaming - something not possible with a DVD player - and then I got intrigued by the whole HD and Blu-ray movie thing.
6. Whew, this hasn't happened yet, knock on wood. My daughter managed to squish her MacBook so that the slot narrowed and that caused some trouble but otherwise I haven't had one get stuck.
