IDVD 6 encoded takes twice as long as iDVD 5?

I did a quick search of archives but if this has been answered and I missed it, I apologize.
I tried upgrading to iLife 6 (since this computer was purchased in December it came with iLife 5). Even using the identical menus I used from iDVD 5 in iDVD 6, encoding times are -at least- double in iDVD 6. To confirm this I deleted iLife 6 and reinstalled iLife 5 and encoded the same projects in iDVD 5 and the time difference really is a factor of 2! I tried the usual: repair permissions, installed the latest updates to iDVD 6 but the differenence remains with iDVD 6 taking twice as long to encode the same project.
Is this consistent with others' experiences?
Is there something I'm missing here?

Thanks John, the old discussion was helpful. It seems that others have found iDVD 6 to be a dog on non-Intel Macs as well and, in some cases, experienced even worse than a 100% slowdown if I read some of the posts correctly.
I hate to think that -this- is how Apple is claiming that Intel Macs are so much faster, by creating Universal Apps that run terribly on non-Intel Macs! My computer is a currently shipping model (I was stupid enough to believe the story that that Intel Pro machines wouldn't be released until 2007). If Apple software isn't optimized for it's own shipping hardware, which seems to be the case... sorry to digress
Anyway, I'll try to have some specific comparison results later after I reinstall 6. I checked and iDVD 5 was running consistently at 230-240% CPU usage with peaks of 270% so it is doing a good job of using the multiple processors (processor performance set to "automatic"). It'll be interesting to see what iDVD 6 does in that regard.

Batch capture takes twice as long to capture

Weird problem. Say I have 3 clips on a single tape (this happens across all tapes and projects) I log them and then select them to batch capture.
All, seemingly, goes well, they cue up and the log and capture screen says "item 1 of 3" or "2 of 3" etc.. but then when it looks like it is done, rather than end, it goes all the way back to the beginning and seemingly re-captures all footage! When I check my capture scratch folder, i only have one file for each capture sequence.
Thus, my capturing takes 2x as long to capture!
any ideas?
thanks
FC Studio 2 (i.e. FCP 6.x)

So it's PAL footage? or NTSC? anamorphic?
Odd though, never seen this behavior, so not sure how to troubleshoot it other than to rebuild your startup disk... (the old sledge hammer approach). It shouldn't be happening though and likely won't with all the setup being clean (as in rebuilding your startup disk). It's all up to the latest too right? 104.11 or or 10.5.2, and QT 7.4.1? FCP 6.0.2, right?

IMovie 08 takes twice as long to produce inferior output

I'm using a Sony HC42 miniDV camera. It records in wide screen format.
In iMovie 6 it takes 9 minutes to save a QuickTime movie of about 2-1/2 minues duration. In iMovie '08 it takes 18 minutes to save the same movie.
The QuickTime from iMovie 6 file is much better quality, perhaps because it uses the true resolution of the source material which is 869x480 pixels. iMovie 08 insists on converting the video capture to 960 x 540.
Samples of both can be seen here:

Query takes twice as long for identical database on two seperate systems.

Hi, I am looking for some help with a performance issue on a particular database.
I am executing the query
'for $o in collection("rx.dbxml")/rx[dbxml:metadata("janusId")="12345"] order by $o/@dos descending return <item id="{ replace(dbxml:metadata("dbxml:name", $o),""", "_") }"> {$o} </item>'
on two different systems through a python xmlrpclib ServerProxy object. This is the my test query but the performance of other queries exhibits the same issue.
The data on both systems is identical and the time required to execute this query is the same for both systems across
every database, except for one. For this particular database, the time required to execute the query on System B is double
that of System A.
This is only the case for one particular database which makes me think that it is a data issue?
However the data is identical on both systems.
Is anyone aware of any data related issues that would cause such a performance hit based on
the different setups listed below? What should be my next step in diagnosing this problem?
System A
- 1 x Quad core Intel(R) Xeon(R) CPU E5450 @ 3.00GHz
- 32 GB RAM
- Red Hat Enterprise Linux Server 5.1 (Tikanga)
- Berkeley dbxml 2.4.13 patched to 2.4.16
- bsddb3 4.5.0
- Python 2.4.4
- Twisted 8.2.0
- SOAPpy 0.12.0
- Filesystem Size Used Avail Use% Mounted on
/dev/sda5 39G 33G 4.3G 89% /
System B
- 2 x Dual core Intel(R) Xeon(TM) CPU @ 2.80GHz
- 12 GB RAM
- Red Hat Enterprise Linux Server 5.3 (Tikanga)
- Berkeley dbxml 2.4.16
- bsddb3 4.7.5

- SOAPpy 0.12.0
- Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 384G 88G 277G 25% /
Thanks for any help.

Try looking at db_stat output for each system for the query itself.
1. clear stats:
db_stat -Z -m
2. run the query
3. look at stats:
db_stat -m
Note any suspicious differences. You can/should also monitor disk and IO during the queries. If the plans are truly the same and the data is the same that points at system differences which would mostly be IO. At least that's the first place to look.

IDVD 6 v/s DVDSP v.s iDVD 8

Hi all! I've been using FCE and iDVD 6 to create DVDs made from SD video shot by me on miniDV cameras and I've been pretty annoyed with the process and somehat disappointed with the results. I used to use DVDSP 1.5 and loved it. I used it in conjunction with an early version of FCE back on my old eMac and the DVDs I made looked great. When I picked up my G5 iMac and upgraded to FCE 3.5 I lost the ability to export to mpeg2 and ever since then I've had tons of problems getting a decent image onto DVD. I've been using iDVD to create DVDs using my exported QT files and I've had pixelating, interlacing artifacts, freezing, you name it. I finally got a decent DVD that plays OK but the quality isn't quite what it was with my old setup. The image quality looks a little softer to me, and the edges of objects aren't as sharp as I feel like they were back when I was using FCE 1 and DVDSP 1.5.
Because of all this, I'm seriously considering biting the bullet and picking up the FCP suite. I'm wondering though, has anybody else noticed this? Has anybody noticed any difference in quality of DVDs created in DVDSP and iDVD? Or what about iDVD 8 v/s iDVD 6? Are there improvements between the versions (specifically in the mpeg2 encoder) that could make my final DVDs look better? Is it worthwhile for me to consider the move to DVDSP? Any advice or recommendations?
Thanks is advance for the assistance and for taking the time to read this.

I'm not certain you'll see the kind of improvement you want. But you will see minor improvements when using 2 pass VBR settings or professional settings, yes.
It also takes twice as long to encode under the pro settings. If you do a significant amount of camera panning (which I personally try and avoid with the use of a quality tripod) and/or you happen to video fast moving objects; then the improvements will be even more noticeable.

IDVD Encoding; Why dose it take so long?

Hi ive been trying to burn a 5gb movie in mp4 format with I dvd on a dual layer DVD, the encoding settings are set to high quality. im using a macbook pro with 2.4 ghz and 4gb ram. the estimated time for it says 80 hours. I left it alone for like 3 hours, closed all other aplications, and now it says 120 hours! thats outrageous. is this normal? and is there any way to speed it up so it wont take more than a day?

Some file types take a very long time to encode in iDVD.
For example, source files encoded with some flavors of h.264 (while highly optimised and high in quality) do take significant effort to decode and play. If the source file has been created in an application like Handbrake where the encoder options can be very complex, then this can happen when used in iDVD.

Differences between iDVD encoder settings

Greetings,
OK, I looked in the forums, Pogue and Miller's iMovie'09 and iDVD book, and on the Web, and haven't found a satisfactory answer.
There are three options: Best Perf., Hi Quality, and Professional Quality.
On the iDVD help page (the same can be found at http://support.apple.com/kb/PH5417) it says, and I am paraphrasing and summarizing:
BP: Background processing available. Good for up to 1-hr videos, and quality will be excellent. preset bit rate. Use HQ or PQ for longer video.
HQ: This is the _best encoding option_ [my emphasis] for videos between 1 and 2 hours long. [OK so far.] (iDVD book and Apple disagree on bit rate; the former says VBR, while Apple seems to imply CBR.)
PQ: uses advanced technology, resulting in the _best quality of video possible_ [again, my emphasis]. Select for projects of up 2 hours duration. Time-consuming.
OK. so what's the deal here?
1) HQ and PQ can't both be best. Or is HQ best as a compromise of some sort, in which case it should specify it?
2) What are the differences for videos of less than 1 hour? Seems to me that you can't improve on the BP setting in this case. IOW, is there any point using HQ or PQ for videos of less than 1 hour?
3) For videos of 1 to 2 hours, does PQ always give better results than HQ?
So, is the following right:
A) For videos of less than 1 hour: use BP, as the others won't improve anything.
B) For videos between 1 and 2 hours: PQ will give better quality than HQ, but it will take a lot longer to burn the DVD, and BP won't fit.
Thanks!

Hi

About so.
iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones
• Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
• Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.
About double on DL DVDs.
BUT -
THE TIME is not just the Movie Duration ! ! !
IT IS - Movie time PLUS Menu time !
And Menu can take 15 minutes (or even more from Movie time)
• Using an elaborated Menu with Sub-menus and Animation (playing buttons) and Audio - Can take a lot of TIME
I use an as simple one possibly - most often "Brushed Metal" from Old Themes - NO animation - NO Audio and this takes less than 1 minute. Resulting in about 59 minutes to my movie.
THEN
I think that I get best possibly result with Best Performances if movie is less than 45 minutes and for all that's more I use the Professional Qualit.

IDVD Encoding/Rendering Error

I've started having a problem burning dvds from iMovie using iDVD. PowerMac G5, 10.4.11, iDVD 6.0.4 and iMovie 6.0.3.
About 60% through the Menu rendering, I get the folllowing Error message:
"Error during rendering/encoding, there was an error during rendering/encoding of the menu/slideshows. Burning process cancelled."
I logged into a different account and it worked fine. Back in the original account, I trashed the iDVD plist but to no avail. I still get the error. I've also used Onyx to repair permissions and optomize the system, but the problem still persists.
Any ideas would be appreciated.

An internet connection makes updating your mac so much easier. I wish I had a dollar for every time I found separate user accounts on the same machine acting completely different from one another .... more times than I can shake a stick at.
I'm currently running iLife'09 on this particular mac so I can't be of much help for iDvd6 updates at this moment.
I'm guessing the most current version is iDVD 6.0.4
Is this what you run on all your macs?

Does iDVD encode dvd's with a particular region on them?

I have relatives in Mexico who I would like to share some dvd's with, but I'm concerned about their dvd players which are typically region 4. Will iDVD encode dvd's with a particular region?

No, DVDs made on your Mac are 'region 0' which mean they will play anywhere. Nor will they attempt to change the region code on a Mac.
Of more concern to you if whether Mexico (Region 4) uses NTSC the same as the US (Region 1). It does!

IMovie too long for iDVD

My iMovie is 1 hr. 17 min. long. After setting preferences to Best Quality, it says the movie is too long for iDVD. How do I cut the movie into 2 sections to put onto 2 DVD's?

STR,
This may not be a practical suggestion for you, but if you had access to a good quality S-VHS recorder (or HI8) , you could export your video to two discs, burning for maximum image quality straight from iMovie, and transferring that material onto a single S-VHS tape or HI8 tape ?
I find the maximum length of PAL video I can burn onto a 4.7GB disc for best quality is less that 58 minutes; above that duration, the quality deteriorates quite badly .

Media encoder takes too long

When I render any sequence, such as a 4 minute sequence, as either a Quicktime file or AVI, Adobe Media Encoder takes many hours to
render it. I had a previous issue where the export quality was too low. Adobe told me to install K-Lite Codec pack. After
that, the quality was better but not perfect. I would render a movie a file and compare the Premiere Pro and original video file. T
he rendered video was lower quality than the original video file. Now, Adobe Media Encoder estimates 3 hours to render a 3 minute SD
AVI sequence or any other type of video file. Adobe Media Encoder never seemed to work properly.
Windows XP Professional and Premiere Pro CS4

hi harm, thank you for the response.
Harm, I have heard that K-Lite might not be the cause here.
That this media encoder problem can be solved without removing K-Lite.
I would not prefer removing it as it has improved my export quality.
Do you have any other suggestions

Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins). How do I fix this?

My Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins) every single time I have shut it down. I try not to shut it down at all now because once or twice, I have got a grey screen, and then nothing. I've held down the power button to shut down again and restart How do I fix all this?

Start up with your built-in Recovery disk by holding down the Command and R keys when starting. Open Disk Utility from there and use it to REPAIR your disk (you've already verified it and it came up with errors).
With any luck, your problems will be solved. While I was there, I would also repair permissions.
Good luck,

My original iPad takes about 5 long seconds before responding to my finger tap in the safari window. Like I tap in Safari window, then count 5 seconds before I can begin typing my search words. Is this normal? I really don't remember it taking so long when I bought it, but it has been this way for awhile. I have closed all open apps many times to no avail. I just reset all settings and still 5 seconds. I don't have a lot on my iPad with plenty of free space available. Also, I have to click twice on many things that typically take one click. Like it highlights it with first click, then second click completes the action that normally would be done in one click, like Facebook like button. Like will underline with click one, then will change to like on second click. Do I need to try to restore from my computer?
Thanks for any help!

Ive tried that but when Im logged in I dont have all the permmisions I should have so it just runs the test for my usernames own little virtual world. Ive been using macs for over a decade now and I have never had my computer do anything like this. while sitting in front of my screen I watched the mouse go to some personal files and change the permissions and then covered their tracks by changing the timestamp on the file dates back. I watched it happpen while all internet conections were off. I had my identity stolen, my facebook password changed, my email accounts closed out. and my firmware password changed all within two weeks of the origninal boot date

Why does exporting HD to a tape take a very long time?

Not a tech problem, really, just a question: just wondering if anyone in here knows why it takes forever to export an HD movie back to HD videotape? I sometimes like to backup my raw footage tapes and have always done so with SD format but HD takes FOREVER, relatively speaking.
On my old SD camera, I could import in real time and watch it on the screen as it imported, and then export back out in real time as well.
Now, obviously HD is a much bigger file format so it's going to naturally take longer and it does, as import usually goes about half speed (I use firewire) but it all gets digitized okay. A full length 60 minute tape takes about 90- 120 minutes to import fully.
The problem is when I want to export that exact same footage back to a duplicate tape. Last night I did one (and it's still going now) that is taking 14 hours to export back to tape. Granted, the duplication is perfect and gets everything on the tape, but it just takes 6 - 7 times longer to do it than it did on import.
So here's my question: why would it import in 2 hours and then export in 14?

Thanks, Andy -- that's exactly what it is. I should have noted in my original post that the videocamera/tape itself wasn't wasn't moving/recording during that long time window, but I was getting a window on the Mac screen that read "exporting to camera" and then below that "Encoding".
I was wondering why encoding was necessary to export and now that I've Googled the term "conform", I see that it's because of the conform process.
Just too bad it takes so darned long.
Thanks for the info.

Why is it that it would take a very long time [if ever] to change or adjust the tempo of a loop in the audio track when i set it to adjust regions to locators? Until now the spinning wheel of death is still very much spinning. thanks for any help.
Is there another way to adjust tempo of loops the faster way, any other technique?

No clue why the final processes have suddenly started to take so long. Two things I'd try: a) capture from an older tape to see if some problem with the new tape is at fault. And b) check the health of your RAM and the hard drive.
The red frame sounds a bit like a glitch we used to have in OnLocation (actually in its predecessor HDV Rack) which was caused by a partial GOP. But that was a product of HDV Rack recording from the live video stream. It turned out that HDV cameras intentionally interrupt the data stream for an instant upon starting to record--specifically to avoid recording a partial GOP to tape. So my gut says that the tape has partial GOPs at the points where you stopped/started recording.
