What can be causing inconsistent DVD video and audio distortions...

Does anyone have any idea why the DVD I burn using DVD Studio Pro (from a 90-min FCP QT movie) - whether it’s compressed by DVD Studio Pro, or through Compressor (with bit-rates of 4 for avg., and 7.2 for maximum) - plays with some serious simultaneous video and audio distortions on my brand new DVD player – that don’t show up at all when played on a friend's DVD player.
As a test, I burned a DVD with just the video, and it does NOT play the same distortions on my DVD player. This obviously means the video distortion is related to the audio being there, but, I don’t know why, or how to begin fixing the problem.
Any help would be tremendously appreciated!

Oh yes, indeedy!
Go into the AC3 encode tabs and have a look around. If you never used A.Pack with older versions of DVDSP then none of this will look familiar, but essentially the tabs are exactly the same as the old A.Pack application.
You can set the desired bitrate - for stereo you don't need more than 192Kbps. You can set the dialog normailsation value (for now, type in -31 and press return) and you can set the compression type - just use 'none'.
This should get you a reasonably useable AC3 file for your project, but as you might guess, there is a lot more to it than that! Head over to http:..www,macprovideo.com and see if you can get hold of the tutorials for A.Pack, or find a copy of Martin Sitter's book for DVD Studio Pro (any version). The chapter on A.Pack is well worth reading and possibly justifies the price of the book on its own.
Once you have got the audio encoding sorted out and are using it on a disc, see if the distortion still happens.
Also, can you describe the distortion that you are seeing?

What should be the quality of video and audio for bandwidth 768KB

Hello Friends
We are provoding 768kB bandwidth for our connection. Can any body tell us what should be the quality of video and audio we can set that does not effect frame rate which is 24 FPS.
thanks in advance.

Hi Samir
You could try out the bitrate calculator at http://www.adobe.com/devnet/flash/apps/flv_bitrate_calculator/ . It lets you try various encoding settings to see what fits best for the bandwidth available to you.

TS3623 I rented a movie and can watch preview perfectly with video and audio feed as signal strength is at top when I checked. However, when I purchased rental video is fine , but I get scratched sound for audio. Any thoughts to fix?

I rented a movie and can watch preview perfectly with video and audio feed as signal strength is at highest when I checked. However, when I purchased rental video is fine , but I get scratched sound for audio. Any thoughts to fix? I rented movie within week and it worked. All previews of movies and show also works.

I have a suspicion that the problem is not in the recording device itelf, but rather in the playback-software, which is struggling with an unfamiliar audio format/codec/whatever-it's-called... I opened the file in QuickTime Player 7 (7.6.6) and selected "Show Movie Properties" and it says:
"Video Track: H.264
Sound Track: Integer (Little Endian)"
All current Mac systems support Integer (both Big and Little Endian) audio natively. The fact you can hear anything at all proves that the audio is playing back. The most likely problem would be a malfunction associated with the mic pickup.

Getting Ripped DVD Video and Audio Into Encore

Do you have previously authored DVDs that need rework? Do you want to add menus with greater impact and functionality? Do you want to add some additional program or supplemental material? Does a client want their product demo DVD to be updated to reflect the capabilities of the new and improved version, but the source files no longer exist? Using Adobe Encore DVD and a freeware utility called DVD Decrypter (DVDD), you can accomplish this quickly and easily.
Disclaimer: I do not support the illegal copying and/or distribution of copyrighted works. The authors and distributors of the software I use have made it clear that they do not support illegal copying. This guide is intended solely to assist you in ripping and copying DVD video to which you have the legal rights. Any use of this guide to infringe the copyright of someone else’s intellectual property is prohibited.
This guide is based on Adobe Encore DVD 1.5.1 and DVD Decrypter version 3.5.4.0. Let’s Begin!
Place the DVD to be ripped in your DVD drive and launch DVDD. If you have more than one drive (e.g., a DVD-ROM and a DVD burner) make sure the one with the disc is selected in the Source dropdown list in the main program window. Now we need to set up DVDD to extract video in a way that is “Encore friendly”. This is the toughest part of the whole exercise. Click on the Tools menu item and choose “Settings…”.
Settings
General Tab: You can leave these set at their defaults if you like. Personally, I specify a custom Default Destination. I put my ripped video assets all in one place anyway, and having a default destination means I have one less thing to do when I rip a DVD.
IFO Mode Tab: Make sure that “Select Main Movie PGC” and “Enable Stream Processing” are checked. “Uncheck Suspect Cells” is probably a good default safety check. If your hard disks are formatted as NTFS, set File Splitting to “None”. I leave “Copy IFO File” checked with the default sub-items checked. Make sure that “Patch M2V Timecode” is unchecked. The items in the Create Additional Files section are purely optional. The author of DVDD has been kind enough to list which programs need which files; notice that Encore DVD isn’t listed as needing any of these extra files. I do keep the “Stream Information” box checked. DVDD generates very informative file names, but I like to keep “Include PGC Number” under File Names checked. Be advised you will get some lengthy file names after DVDD is finished ripping.
Stream Processing Tab: Since we enabled stream processing in the IFO Mode tab, we need to tell DVDD how to process those streams. To save yourself time and confusion later, check the “Convert PCM to WAV” box. Earlier versions of Encore required a Demuxed audio stream and a Raw video stream. Encore 1.5.1 can accept either type of video stream (Raw or Demuxed) but it does still require a Demuxed audio stream. However, I still recommend using Raw video and Demuxed audio, if only because it seems to be somewhat faster to process in DVDD. This workflow is also backward-compatible with earlier versions of Encore.
So let’s set up the Stream Processing tab now. In the Demux box, enter “0x8? 0xA? 0xC?”. This ensures that all audio streams in the selected PGC, whether AC3, PCM or MPEG will be set to Demux. In the Raw box, enter “0xE0”. This ensures that the video from the selected PGC will be set to Raw.
Additional Notes about the Stream Processing Tab:
1. For those of you asking the question, “What the heck is a PGC?” it’s just DVD-speak for the titles in a DVD project. And I’m not talking about the opening or end credits, either; I’m talking about the titles that result, for example, from the timelines you create in an Encore DVD project. There is a subtle difference between a PGC and a VTS (title set), but that's not important right now.
2. Happily, recent versions of DVDD create a WAV file after ripping that will import directly into Encore. Versions prior to 3.2.0.0 would create a WAV file that had to be imported to, and exported from, a sound editing program like Adobe Audition, Goldwave or SoundForge before Encore would recognize it.
Events Tab: For convenience sake, I recommend setting “Set Program Mode” in the Startup section to “IFO”. That way, whenever you launch DVDD, it will look familiar to you. You may safely ignore all of the other tabs in the Settings dialog.
Ripping
1.Under the Input Tab of the main program window, select the PGC you want to rip. You can only do one at a time.
2.Switch to the Stream Processing Tab. Verify that Enable Stream Processing is checked.
3.Check or uncheck any or all of the video and audio streams that are listed. Highlight each one to verify that all audio streams are set to Demux and the video stream is set to Raw.
4.If you didn’t select Default Destination in the General Settings Tab, then you need to tell DVDD where to put the ripped files now.
5.Click on the big DVD-to-Disk icon.
6.DVDD will announce, quite loudly, when it has finished. At that point you can rename the files or import them as is into Encore.
I hope you find this guide useful and that it helps you get the most out of your investment in Adobe Encore DVD.

OK, I can't tell you what we are doing, you'll have to trust me that it's for a very good cause. I'll simplify the use case as an example. If I can do the following we'll be OK:
1) Read video/audo files from a DVD that we created
2) Open these files with the QuickTime Player, click on Export to Apple TV to create an output file.
I'd rather not do an interim conversion of the video data (like use a 3rd party app to convert to mp4 first and then read into QT, but I'm considering a conversion to DV) because that could seriously hurt the apps effectiveness. I also can't use another app (MPEG Streamclip, HandBrake, VisualHub, etc.) to do the conversion.

What do I need to transfer video and audio from my 2009 Macbook to my television?

I want to watch a movie with my family tonight, but the DVD is broken. I was planning on renting the movie online and transferring the video and audio from my Macbook to the television. What cables will I need to accomplish this? Also, does anyone know, were I to use a Windows instead, would transferring the audio be simpler? (And what would I need to do that?)

Try doing it without a cable!
Use AirDrop, described here:

UPDATE - Oh, sorry, I see the article points out the MacBook is too old for AirDrop.

Can I export both the Video and Audio from Soundtrack Pro? or just audio?

I opened a video in STP and added some effects to the audio. But I do not see any video export options??? Can I only export the audio??? How do I add the New audio to the final video???

Thanks for that Soundaround. I tried to use the encoder option as well, down to an .mp4 file, but the video did not play properly. The source material is HD 1080i .mov and the frame rate was default, set to 100% of original.
Do you know Why this is? I also tried the same conversion in cocktail and got the same results. Can I only compress down to an HD .mp4? I want to retain normal sync and smooth playback?

Mpeg2 DVD VOBs Video and Audio into QuickTime ?

How can I read the mpeg2 VOB files from some DVD that we created into QuickTime Pro with the MPEG2 playback component ?
We have an app that does video and audio processing built on QuickTime. After the processing is done the result is written to an mp4 file using QuickTime export. We now have to be able to read DVDs that we create into this app (QuickTime), and after processing we must se the QuickTime export option to create the mp4 file. These are not commercial DVDs and are not copy protected. I'd like to just be able to read the mpeg2 video and audio directly into QuickTime but I haven't yet found a good way to do this. Here is what I have tried:
1) I can read individual VOB files with QuickTime, but I don't get any audio and I need all the VOB files as one.
2) I have used MPEG Streamclip to open the DVD VOB files and exported the demuxed mpeg2 video and aiff audio. Both files open together in QuickTime but since the total size of the video is over 4 GB the video and audio are off and drift more so throughout the video.
3) I used libdvdread to read the DVD and create a single MPEG2 file. This can be read by QuickTime but I don't get any audio. From what I understand this is muxed video and audio which QuickTime doesn't understand, but is playable by VLC.
I think I could probably ulibdvdread to read the VOB files into a muxed MPEG2 file, then use ffmpeg to convert this to a very large DV stream, then import that into QuickTime, but there has to be a better way than to do the lengthly and large file size conversion to DV which is not a format I ultimately want.
Before we go and write our own, I'm looking for a simple way to read the mpeg2 video and audio from a DVD format directly into QuickTime and preferably something that can be integrated into our app and not use another commercial stand alone app.

How can I use QuickTime to make a screen recording that has both video and audio?

How do use QuickTime to make a screen recording that can be saved with both video and audio together?

do you know of any software that would record a QT movie playing on my Mac screen with both audio and video?
I have used Ambrosia's Snapz Pro X ($69) for years, but they are currently upgrading their Kext (Kernel Extension) software for changes inroduced by the Lion release so it might not be your best bet at this time. I also use ScreenFlow but it is a combination capture and editing utility which runs $99 and may include more features than you may need or will use. Have also tried Screenflick ($29) which, to some extent, appears to have a functionality somewhere between that of Snapz Pro X and ScreenFlow. It is a bit more complicated to set up but for the price might be the best bargin at this point. All three can capture the entire screen or a portion thereof, with or without mic/line and/or system audio. (Or at least they all will as soon as Ambrosia updates its Kext routine.)
Here is a URL link posted by QTKirk three days ago to an article that recaps of a number of currently available third-party screen capture apps from around the world several of which may interest you: http://mac.appstorm.net/roundups/utilities-roundups/10-screen-recording-tools-fo r-mac/

Can I save both DVD-R and DVD-Video files onto the same DVD?

Can I save both DVD-R and DVD-Video files onto the same DVD?

Hi Stan,
I just want the user to be able to run my video clips either on a
computer or on a standard DVD player. It would be nice to include both
formats on a single disc. I am new to this and am not sure what format
is most widely used for standard DVD players. Thanks for your response
and any guidance you can give me.

Can I use iMovie to edit and enhance both video and audio of my homemade DVDs?

I have a lot of homemade DVDs converted from old VHS tapes. The video and audio quality need to be edited/enhanced. Can I use my iMovie 11 for this task? If not what are my options? Thanks.

Hi
There are several layers to this Q
• VHS-tapes has a low quiality as is
• converted to sort of .mpe2 to a DVD to be played on standard DVD-player - Quality is futher lost
• converting it back to DV or AIC - and more quality is lost
• edit it in iMovie'08 to 11 - even more quality is lost due to that when going from Event's to Project's - every second line building up the picture is discarded (as non of them - iM'08 to 11 - works woith interlaced SD-video
So if quality is of any interest - I would - and are doing
• Converting from VHS-tapes
- via a CANOPUS ADVC-300 - to digital
- in via FireWire to
- to iMovie HD6 or FinalCut (any version) - asa they all keep 100% of the interlaced SD-quality
- edit and put out on miniDV tape (still 100% preserved) or to a DVD made in iDVD with all that keep as high quality possibly. (No Video-DVD can keep 100% quality - it's due to standard and amount of compressing)
If Quality is of no importance - then
• DVDs needs to be converted to DV or AIC and this is no free standard on any Mac - You need a converting program as
- MPEG StreamClip (free on internet) + BUT it needs the .mpeg2 Component from Apple to work ($20)
- Roxio Toast™ - can also be used to back engineer - BUT this cost's much more - still to me all extras was more than worth it
- Analog way - DVD-player - A/D-box - import via FireWire

Video and audio out of synch on burned DVD. DVD project appears to be fine. I'm using 1X speed to burn disc. Project info indicates plenty of space. What should I do?

Video and audio are out of synch on some chapters of a burned double layer DVD. The iDVD (7.1.2) project seems to be fine. I'm burning the DVD using a 1X speed. What else can I do to solve this problem. Based on the project information, I have plenty of space relative to the DVD capacity.

Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

Every time I try to add a new video to my photo folder...iTunes says it's experiencing a problem and then it crashes and shuts down. What can I do to add video to my photo folders?

Hi mterry1723, one solution that might be worth trying is this:
- Close iTunes, if it's open
- Open Safari and got to 'Preferences'
- Select 'Security' on the top
- Untick all the security options in the menu
- Click the 'Show Cookies' button and look for all the 'apple' entries in the left-hand column.
- Highlight them (select them collectively) and press 'Remove'
- Now open iTunes and buy the song as usual.
- You may be asked to do the same security process as before, so do as asked.
- Hopefully, the security check will now have accepted your answers and start downloading the song as normal.
Remember to re-tick all the required security options you had just un-ticked in Safari preferences. You don't need to bother about opening the cookies again.
I hope this has worked for you and my profoundest apologies if it has not. Worth a go, though!
I did see this thread: https://discussions.apple.com/message/18259935#18259935 which may be of more help, mainly the last entry by 'c2boyd'

I keep getting the "connect to itunes" screen and have to restore my ipad. it will also drop the wifi connection every few mintues. what can be causing this?

I keep getting the "connect to itunes" screen and have to connect to itunes and do a restore on it. It will not pick up my ipad so I either have to do a restore or restore to new and it will work fine for a day or so except for dropping the wifi connection. What can be causing this? I have had this pad since January of this year and have not had any problems until recently.

If you have to keep restoring your iPad with iTunes repeatedly and there is no change after restoring as a new iPad or not from the iPad's backup, your iPad has a major problem - likely a hardware problem. The iPad includes a one year warranty. You can call AppleCare or make an appointment at an Apple store if there is one nearby.

What causes this? Video or Audio freeze on plays?

I have a new HP Pavilion 23 AMD 6 with 3.6 processor.
During video plays the video and audio will freeze but the audio is there too with the last input blurrping out like a loud F**T. That's the best I can explain it. It is only for second or so but annoying.
Here's a monkey in the works. The large screen TV does it too. Here's the conundrum. I think the PC did this before I switched to Comcast, about a month or more before Comcast was introduced into the equation. The first knee jerk would be to blame Comcast since the large screen tv does it too. However, I have never noticed it on the tablet, netbook or older Toshiba laptop. ???? So that might let Comcast off the hook, although it is odd that the new HP and the TV both do it.
Is there any issues with the audio or video card on this particular PC or a setting that could help? Here is a clip of the Device Manager and I trust I've shown the audio and video pertinents. I have used all the updates that this pc has asked for.
Thanks so much for any help! ":-D Jack

I know your pain... I have battled with this for years. My system is a Pavilion dv7 laptop. I am constantly plagued by the audio system, which frequently f*rts, and even more frequently, skips (backwards) a short time during playback - it's doing it right now! Sometimes, every few seconds. Other times it won't happen much at all... with no apparent difference in what I am doing or running.
Some things I can add to this thread:
1. The audio sucks regardless of the source !! I've seen other threads where streaming over interent was discussed - for me, I get the issue:
     a) audio/video browsing eg youtube or streamed webinars etc
     b) playing local music, ie iTunes .mp3 files saved on local disk
     c) playing from CD/DVD drive
2. I run a system with all the latest drivers from HP, WIn 7. No games or other crud.
I have seen many people comment with symptoms which I am sure is the same issue - for years. Wish someone could finally come up with a fix - it is a real sytem problem.
