An investigation of times required to burn DVD during 'audio' phase.

These figures are for a 1 hour 40 minutes movie, with 3 tracks of Audio, trying to save to disk image on desktop. 80 Gig of HD free.
When iDVD appears ‘hung’ it is actually saving to a file, called ‘tempmovie.mov’, in the iDVD project, which in turn is actually a package. I used a spreadsheet to track the size over time of this file, which hit a max of 1.01 GB in my case.
• First attempt, 3 audio tracks....
Rendering Menu/Assets took 3 1/2 hours.
Rendering Audio
- Phase 1. iDVD ‘locked’ and ‘unresponsive’. Rendering the file tempmovie.mov took 42 hours using up to 80% of processor time. iMovie used 12-18%. Initial spurt of several hundred Mb of file size in an hour, then about 100 Mb in second hour, then adding to the file at a low of 10 Mb per hour, high of 15 Mb/hr.
- Phase 2. Spinning activity wheel (burning wheel?) started back up after indeterminate time (running at night). New file called ‘CurrentAudio’ created, but not added to, no files ‘growing’. iDVD unresponsive, but not marked in the Activity Monitor as such. Menus greyed out.
Rest of audio terminated after waiting 60 hrs with iDVD using average of 13% processor time. I gave up on it, had to force-quit. iMovie was using about 8% of the processor time.
• Second attempt...Single audio track.
Trashed old iDVD project. Opened iMovie file with Garageband; took 41 hours processing time to merge the 1 stereo track and two mono tracks to 1 stereo track. Saved audio as two stereo tracks of 192 bit AIFF in less than 10 minutes. Exported it to iTunes.
Turned off two tracks in iMovie file (top & bottom tracks), erased third (center) track and imported Garageband track to center via iTunes. Sent to iDVD.
Rendering Menu/Assets took 3 1/2 hours
Rendering Audio
- Phase 1. iDVD ‘locked’ and ‘unresponsive’. Rendering tempmovie.mov took 16 1/2 hours, max. 80% processor for iDVD, max.12% for iMovie. Initial spurt of 240 Mb file size in first hour, then about 130 Mb in second, 90 in third hour, 66 in fourth, average of 45 +/- 6 Mb per hour after 4 hours. At end, 20Mb file ‘CurrentAudio’ created.
- Phase 2. 14 hours at least spent with iDVD only using average of 2% of processor, iMovie using 5.5%. No spinning ‘burning’ wheel. Again, iDVD was unresponsive, but not marked in the Activity Monitor as such. I terminated the process with a force-quit.
• Third attempt. Trashed, then re-installed iMovie & iDVD, with updates. Single audio track, erased the turned-off bottom track, as Activity Monitor had showed iDVD still opening the clips from the turned off bottom track during the second attempt.
Trashed old iDVD project. Made small edit to iMovie project. Changed destination for finished disk image to Movie folder rather than desktop.
Rendering Menu/Assets took 3 1/2 hours
Rendering Audio
- Phase 1. iDVD ‘locked’ and ‘unresponsive’. Rendering tempmovie.mov took 1 hour 45 minutes. Initial spurt of 600 Mb file size in first hour, then about 570 Mb/hr for balance. max. 88% processor for iDVD, max. 3.2% for iMovie.
- Phase 2. 11 minutes to save disk image.
Conclusions.
Using three tracks of Audio increases the rendering time enormously (42 hours for audio).
It also pays to erase unwanted tracks in iMovie rather than just unticking them (16 hrs vers. 1.75 hrs for audio).
It takes the same amount of time to render three tracks in iDVD as it does to export them to Garageband, (and you still have to re-render in iDVD afterward).
Either iDVD doesn’t like saving to the desktop, or I had a corrupt/missing file that prevented saving the disk image. Probably the latter.

Brian,
this year's price "Most Longanimous Person of The Year" belongs to you!! THANKS for you efforts and reports..
you've probably read Karl Petersen's reports about some mysterious "benchmark", when an iM project gets stuttering/unrespondsively due to "too many" audio clips..
.. I'm actually producing my Xmas gifts.. 55min project = 2h encoding ... (see spec below) ...
but: I'm editing my iM projects mostly on an external harddrive; and it is a "habitual ritual" of mine, to import the final movie as QT/Full Quality file onto my internal hd, THEN fire-up iDVD => never had any trouble with audio-encoding; my videos are "solid" dv-streams ...
so, how about adding that (single dv-stream of your movie) setting to your test set-up ...?
and: why the hack 1:40h for testing?? why not ... 5min? ;-))
happy holidays ..

Apack sounds fine - Simulator/burned DVD definite audio pumping

Can't understand why after many days research/testing/fiddling I cannot seem to get the AC3 audio to play cleanly in DVD SP 2 simulator or when burnt to DVD...the FCP 4.5 audio is set between -12 and -6 (peaks), export as aiff files, compress in Apack at 192 kbs, stereo, -31 dialnorm (return entered), sounds great/fine when played back in Apack...import into DVD SP 2 and there is definite gain pumping or whatever one calls it throughout some tracks. Host will be speaking, at certain points, the volume will rise up, then the level will dip down for a second or two, then rise back up a bit even increasing the background hiss just a bit, then remain constant for a while, then rise up/down again...at least this always happens in the same places.
Wonder why only in DVD SP/burned DVD does this happen, and how does one overcome this? Very annoying.
Thanks much

Just to be sure - are you hearing this in DVD Player or on a set top player?
If you look in the DVD Player preferences, have you got the disable dolby dynamic range compression checked or unchecked?
If unchecked, this can give you the same effect as you describe... so try checking it and playing the disc again.

Burned DVD loses audio near the end.

I am running IMovie 11, IDVD 7.12 on an IMac 2.7 Ghz i5 OS 10.8.2. I worked for about two months creating an IMovie that covers my family's entire seventeen day trip to Greece and Istanbul. It has a lot of title slides that explain in detail what we saw. I purchased copious amounts of Greek and Turkish music and appropriate sound effects. The Movie is about 150 minutes long. I previewed I Movie and it worked great. I transferred to IDVD by using share IDVD. I chose Professional Quality and wide screen, NTSC and Dual layer disc. The DVD preview worked great, however after burning the disc there were two problems. First, the intro theme with drop zones and scene selections failed to appear. I suspect that was because there was something on the initial menu tile in the map. I suspect that created an autoplay but won't know until I burn another copy. Does that make sense to you?
Second, at about the 130th minute all of the audio was muted. Pictures and video footage were there also all of the title slides but no audio. I called Apple Support and since I am still qualified under Apple Care they agreed to help. First attempt was to delete the previous encoding and re-burn. that took three hours but the disc had the same problems. (At that time, neither myself not the apple tech thought about the autoplay feature, as I was most concerened about the audio problem.) After that disc failed again I called Apple Support again. This time we cleared out the autoplay function, trashed the two preference files for IDVD in the preferences folder and shutdown the computer. I started it back up by zapping the parameter ram. Option, Command, P and R buttons on start-up. I am currently re-encoding and reburning another dual layer disc. If this doesn't work, could the problem be the size of the project? Is there any way that I can take my IMovie project and split it into two sections of about an hour and fifteen minutes each then burn them through IDVD to two different discs? If this would work please tell me how to make a copy of my IMovie project and how I can split it in two. Also any other ideas anyone has would be greatly appreciated. TIA

Hi
Can it be so that You use DL-DVDs ? They can be problematic - I only use SL-DVDs
Else
No audio on DVD disc.
Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an Audio-CD .aiff (Same as played on standard Stereo CD - no .mp3)
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser (iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as MEDIUM (or ev. as Large)
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provoking it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.

Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies — except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format — that I have noticed.
7. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)
Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple’s Disk Utilities application
• OR burn with Roxio Toast™ if You got it

Burned DVD loses Audio while playing

So i have tried to Burn a movie twice using both High Quality and Professional Quality performance to do it. The movie will play (theres no slide shows or pics or anything) for a while just fine, and then about 10 minutes in the sound disappears for the rest of the movie (and its two hours long!). When I play it in IDVD preview it plays just fine, same with the actual file playing in quick time, so its not my file thats messed up. I have no idea how to fix this. Any clues?

First, are you using music purchased from iTunes? If so, you should take these preliminary steps.
1. Burn the music in question to a CD.
2. Reimport the music as an AIFF file. iTunes>Preferences>Advanced>Importing>Import using: (drop down menu) AIFF encoder
3. This music can now be imported into your project.
Before you burn a DVD, you should first create a disk image. In iDVD, go to File>Save as disk image. Doing so will allow you to view your project on your computer's DVD player. You will be able view your project exactly how it will play once burned to disk. That enables you to find and correct any errors before burning a disk.
I hope this helps.

After burning dvd, the audio out runs the actions or speaking

after the dvd is made and i play it back on a dvd player, it is as if the audio is being heard before the actuall speaking. why is this?

They were all encoded in compressor and all are about 7.6 Mb/s. The thing is, only 2 of 14 have the issue. Granted, they are the 2 longest, but not by that much. And it is out of sync for the entire program, it doesn't gradually get out of sync. Also, opening the Video_TS folder (on the computer, not the disk) in VLC shows the same problem, so its not the player, the disk media, or even the burning process. It's somewhere in the "build" process. I will try a lower data rate for those two, but it should be fine for less than an hour of material.

Burned dvd plays audio but not video

I just completed the first part of a wedding video and it burned fine. I just finished the second part and it looks and plays fine in imovie and idvd preview. However when I burn it and try to play it the dvd will only play the audio. the dvd starts like it's going to be fine, but the video stalls on the first frame and the audio continues. does anyone have any suggestions. I am trying to avoid starting over, but I don't know what else to do. I tried eliminating the first clip in case it was corrupt, but that didn't help.

First thing you might do is in iDVD, use the menu option to "Delete encoded assetts" in case the previous garbage from the last project or burn is messing things up. If that doesn't work here are my standard list of things I do when I have issue or even just before I go to burn a new project...
Run Cache Out X (free download) to clear all system and application caches.
Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system.
Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
Reboot your Mac.

Burn DVD, get audio but black screen and no video

Hi. I'm using iDVD 7.1.1. I exported a short movie (720p, 16:9) from Final Cut Pro (export as Quicktime movie) and stuck it in my project. It looks find when I preview it but when I burn the disk (Professional Quality encoding) I get a black screen after I click through from the menu, though I can hear the audio. Please help!!
(I'm using a MacBook Pro i7).
Thanks

Hi
A. Try to do a DiskImage first. File and down to Save as a DiskImage - test this with DVD-tool to see that it runns OK
B. Free space on Start-up hard disk. How much ?

N500 Optical drive will not burn DVD's

When I try to burn a DVD +R with the internal Optiarc DVDRW DL in my N500, the drive acts like it is trying to read the disc and then ejects it and asks for a disc. I have tried several discs, each with the same result. I was able to burn DVD's from the same spindle with no problems on other machines.
The drive reads DVD's and will burn a CD.
Any clues as to what could be done to fix it?
If it's not fixable, can I get a replacement DVD drive. I cannot find one on the Lenovo parts and accessories web pages.
Thanks,
Tim Holmes

I'm burning dvd's that won't play on a regular dvd player. What am I doing wrong? Are there some simple things to check to figure this out? (Sorry, I know this has been asked many times)

I'm burning dvd's that won't play on a regular dvd player. What am I doing wrong? They play fine on computers but not on dvd players. Are there some simple things to check to figure this out? (Sorry, I know this has been asked many times). Created in DVD studio pro.

Hi
Just my thoughts to add to the excellent answers above.
• BRAND of DVD used - Matters when doing Video-DVDs
Memorex, NoName etc cheap brands usually do NOT work
I only Use Verbatim (more organic dye in these)
• Type of DVD - matters
- DVD+/RW - usually results in problems
- DL-DVDs are more problematic than SL-DVDs
- DVD+R are a more modern sort - BUT PLAYS BADLY or not at all on older DVD-players
I only use DVD-R
• BURN SPEED - matters
- Best in iDVD app - IS NOT BEST at all but results in lot's of Burn Errors = Doesn't play well or at all
I set this down to x2 or x4 max.

Burn dvd from quick time

how do you burn DVD using remote dvd

Hi
<5Gb most often not working and the DVD most often ruined.
I never go under 25Gb free space on internal start-up boot hard disk.
Yours Bengt W

I repeatedly get "error during rendering/encoding of menus/slideshow" message. This process is the same on my iMac, MacBook and another iMac. I have been burning dvd's int he same way for the past 12 months using the exact same steps successfully.

I keep getting "error during rendering/encoding of menus/slideshows" message. I have been burning DVD's in exactly the same way for the past 12 months and mostly on my MacBook which is 3 years old. Obviously I'm using iDVD. I purchased an iMac about a year ago and moved to use this for dvd burning without problem. A few months ago (approximately) I started to experience problems with burning with the error message above. I tried everything including starting the whole process from scratch right down to capturing the movie clips from my video recorder into iMovie, then using them in iDVD. Still the same message came up. I lost count of how many times I repeated the process with different clips and variations and the same thing happened. This was also the case with my MacBook and my husband's iMac.
After taking both of mymac's tothe service centre, having new optical thingys put it and even a new hard drive on my iMac along with a new DVD burner the same thing happened. They told me it must be the process that I am using that is incorrect!
I took my 27" iMac to an apple shop and asked them to assist me while I use the same technique as I always had. The same message came up so they tried using my clips in one of their mac's. The same message. They tried it with different clips and the same message. The only way we could get theirs to work was with a magic DVD which did not produce what I needed and was limited with only one page.
I now cannot use any of my Mac's for the intended purpose that I bought them for - to produce good media for my work! It was suggested that I purchase some non Mac software to burn DVDs which defeats the object of having a mac with iDVD in my opinion. I have a book on iDVD which is very informative and have followed the process to the letter and checked all the trouble shooting and still no remedy. It was mentioned that an up-date may have caused the problem on all my macs.
I feel that this issue should be addressed by Apple as a matter of correctness.
I now find that on the net there are many posts in forums and such like with exactly the same (almost word for word) problems. Please Apple, keep/regain your good name and sort this out.

Thanks Bengt W for your attention to this matter. So much appreciated. And thanks for putting me right on the aim of forums (new to this). Although, you may regret asking for more information. I've added everything I can below.
The process I used is as follows:
Import recorded clips of between 5 and 15minutes each from my video recorder into i
Edit the clips (remove unwanted start and endng)
Add title to front of clips
‘Share’ them to ‘movie’ (export using QuickTime)folder in .mov format individually
Open iDVD and ‘create new project’
Select ‘favourite’ theme that I have set up forall my work dvd’s (this has been used successfully many times and I’ve triedwithout using the favourite them).
Add 2 submenus for each group of clips
Select submenu - drag and drop between 3 – 6 clips in each of the twosubmenus
Change title colours on clips
Dragand drop image into drop zones where required
In‘map’ view I check for any yellow warnings before burning to disc
In an attempt to remedy the problems I’ve tried the following:
Try new DVD discs
Try different themes (favourites and standardones)
Change images in drop zones
Start whole process again even from importingfrom camera again
Two other completely different computers (iMacand MacBook) with iDVD
Go to apple shop and use their computers to doin iDVD
Try with one clip and no menu pages added
Use a clip that I already have that did notoriginate from my camera
Turn computer off and restart
New hard drive
New optical lense (thing)
New DVD burner
Saving to disc image rather than dvd disc
Other points:
I also have a ‘flip’ and ‘iPhone’ whereI’ve imported footage camera which, although limited, records and makes videoclips and burns them to DVD through iDVD without problem.
For example, I have just gone through steps 5 - 11 using some clips that were already imported from my iphone to iPhoto and dragged across. I used a theme that I've used before which has failed and added one sub menu page where the clip went. It burned to disc image successfully.
The startup disc, I believe will have no space issues asit’s a new hard drive with no use apart from this. That could have been an issue before (I didn’t check it) butnot now.

Video "jigsaw" artifacts appear when camera pans on burned DVDs

I've been pulling my hair out for days as I export endless new sequences at different settings and then burn DVDs, only to find that the problem does not go away. The issue is the infamous "jigsaw" artifact effect, or whatever you want to call it, meaning that when viewing the resulting DVDs, when the camera pans, images "tear" and kind of spazz out. This seems most noticeable when panning past straight vertical objects, but is not limited to only this circumstance. My suspicion is that this is all the result of an interlacing issue in iDVD, but I have certainly learned that I am capable of overlooking the obvious or being wrong. What I don't understand is that with all of us out there working on Avids and using iDVD, either there does not seem to be a unified ideal export setting that resolves this issue, or I am having a comparatively unique problem. The shame is that most of the DVDs are looking great, and it is only this one issue that is sabotaging completion of this project. I'm at my wits end, so any and all knowledgeable help is supremely appreciated. Help me keep my hair.
When viewing any of these exported clips within quicktime player, the jigsaw is not visible. But when viewing the burned DVDs on my Mac, the jigsaw is visible.
When viewing the burned DVDs on my Panasonic HDTV (TH-42PX75U) the jigsaw is visible. When viewing the burned DVDs on my Sony Trinitron Production monitor (non HD), the jigsaw is visible.
Avid Software: Avid Xpress DV 3.5.0
Editing system info: Mac G4 "Mirror door" model - Dual 1.2 Ghz PowerPC - memory 1024 MB
OS Software on Editing System - OS X version 10.2.3
Quicktime version on Editing system: QT version 6.3
Software used to burn DVDs: Idvd 8 version 7.0.1
Computer used to burn DVDs: MacBookPro3,1 - Intel Core 2 Duo 2.2 GHz (codec downloaded from Avid and installed - prior post about video not displayed in QT exports was due to missing codec)
Quicktime version on Computer used to burn DVDs - QT Version 7.4 (92) (with Pro upgrade)
DVD media used: TDK DVD-R 8X 4.7GB
Info on sequence I am burning - A 1 hour and 50 minute program of African wildlife footage all shot on regular mini DV tapes. Camera used was the Panasonic AGDVX100A on the 24 frame setting that does not require a software fix (the correction is done in camera). All the footage was digitized using this camera. When viewing any of these exports afterward within quicktime player, the "jigsaw" is not visible. It only becomes visible after burning them and then watching the dvd. All burns in iDVD 8 are using the "professional" burn mode.
Export settings from Avid and iDVD 8 result summary -
1) Exported at "same as source" from Avid yields arguably the absolute worst result, as I rather suspected with the whole field / interlacing issue, but I was feeling hopeful.
2) Trying to bypass Quicktime by using "dvstream" as the export setting also yields a very poor result. This jigsaw problem does not occur, but the resulting image is terrible. Very milky blacks, the compression is worse, as in much more noticeable, than any other export, and the image is soft and thin looking, rather anemic, and it ruins the visuals completely. What is a bit odd to me however is that I had been using dvstream to burn DVDs of other projects for years on prior versions of iDVD and it never seemed to be a problem. As I tried this one first, without having the Avid codec installed in my MacBook (which I use to burn as I can run iDVD8 on it, also meaning that trying quicktime reference is not an option, I must export, then move the completed export to my macbook pro), I am currently exporting it one more time to see if installation of the codec fixes the horrible compression and color result, but I am not hopeful at all.
3) Tried using an Avid forum suggestion that recommended using 720 X 480 - crop/pad - RGB color levels - even (lower field first) - native dimension 720 x 480. No good.
4) Another Avid forum suggestion to try the "Animation" setting for video
instead of "Avid DV" is not a viable option. The infamous "2 GB limit" message
comes up as the export nears completion and aborts. This message does not appear
with any other export setting. When cutting my sequence in half, the same problem occurs. Even if I could get it to work, the result would be useless if it meant I had to send people several DVDs of the program chopped up into little bits.
5) Heres a summary of other export attempts all using Quicktime movie and "Avid DV" for video, keeping in mind the info I read about how at least one version of iDVD had the field order (ntsc vs pal)reversed a while back. I would expect that Apple has fixed this problem by now, but just in case...
a) odd field - 720 x 486 - 601 - crop/pad - 4:3 Non-square
b) odd field - 720 x 480 - 601 - crop/pad - 4:3 Non-square
c) even field - 720 x 486 - 601 - crop/pad - 4:3 Non-square
d) even field - 720 x 480 - - 601 - crop/pad - 4:3 Non-square
Suggestions to buy a different dvd burning program or new software are nice and all, but I simply cannot afford it. I also have a fear that if I were to try a different program that the same darn thing would happen, as no one seems to be able to say with 100% certainty that this specific problem would be fixed. The only thing that would be worse than my sense of hopelessness and helplessness at present would be spending more money and still not having this maddening issue be resolved.
Help... and thanks to any of you who take the time to read this epic length post and reply!

PROBLEM SOLVED! Thanks to having downloaded Toast 8, the dreaded interlacing has disappeared. The first test made me nervous. I exported from Avid using Sorenson and using the "automatic" settings for Toast's detection of fields etc. The DVD still had the jigsaw at the same spots, but it was not as pronounced as some of the tests with iDVD. I then exported "same as source" and used the advanced settings in Toast to tell it "lower field" and maxed the compression settings as much as I could without exceeding disc space. The DVD result is the best looking I've seen so far and all interlacing artifacts are gone! Thanks to Blackdog at the Avid Forum. I now know this interlacing problem was 100% the fault of iDVD 8 and will be using Toast from now on.
