iDVD burns disc, but blurry motion

Laura:

Welcome to the Apple Discussions. What is the playing time of the movie? If it is less than 120 minutes including menus you can burn it to a single layer DVD-R disk.

What speed did you burn it at? It's best to burn at the slowest speed possible to get the highest quality burn. Also try using the Professional Quality setting. Are you saving as a disk image before burning to disk? If not it's a good way of checking out the encoding before burning. You can mount the disk image and play it with DVD Player. If it plays satisfactorily that way then it should play that way if it's a good burn and good media. Verbatim DVD-R disks is the brand most recommended.

You have some top notch advice from OT here.... Suggest you follow it to the letter.


Also, if by chance you still have no joy with the completed /burned DVD, then try using Roxio Toast instead of iDvd to burn it to the media mentioned above by OT (which I will also second). Verbatim is best but Maxell would be my second choice.


Btw, Have you tried burning as a QT reference movie as opposed to a self-contained movie to reduce the size of the above 80 min. / 125 GB !!! file?

Good luck & good night.

All good advice.

However, I want to know what codec you used to export an 80-minute movie that created a 125GB file? iDVD will be expecting something along the lines of a DV file which is 13GB/hour. The preview function is merely showing you your uncompressed file, so it should look the same. If you follow the advice above (making a disc image) that will show you the actual compressed file.

I'll keep a close eye on your progress and good luck.

Laura:

Make sure you have at least 25GB free on your boot drive and don't let your computer sleep during the save as disk image process.

OT

What was your source material? How was it captured?

Very glad to see you and Mike goth this worked out. I wish I could of offered more help but I always start out shooting in DV-NTSC hence I don't encounter this issue often. That and I always launch i-apps (or pro apps) when my camcorder (TRV900) is actually plugged in to the computer and most of the time the app will default to the correct settings.

@Mike ...... well done.

I have run into a similar problem. I have been trying to burn a DVD with several quicktime videos (a little less than 5 GBs total) through iDVD, but I get the motion blur problem with the end product. I changed the encoding to best quality which has reduced the motion blur (at least in the disk image... I haven't done a burn of it yet), but I was wondering if anyone had any suggestions to fix the problem completely. It's a large project. The runtime is a little over two hours, so it's on a double layer DVD.

There is no sure fire way to get rid of motion blur completely when shooting under 30 frames per second / 29.97. But you can reduce its effects by following seven simple rules:





1. Use high quality encoding (depending on run time). This doesn't mean setting it at best quality but rather at Best Performance or Pro settings when appropriate and called for.


2. Keep video playback under 60 mins. whenever possible. ( And remember that slideshows, added audio, motion menus, etc. use up space on the media itself and hence reduce available playback at its highest quality).


3. Use video footage with little or no camera movement in terms of panning or fast moving objects.


4. Make a disc image to the desktop and test the image with apple's dvd player app prior to burning the movie to DVD-R.


5. Lower the burn speed to 4x or lower.



6. When you exceed 60 mins. of QT playback (and up to 120 mins max) use Dual Layer media instead of single layer.



7. Use Verbatim or Maxell DVD-R.

I've been trying to figure out how to lower the burn speed but haven't been able to find where to do that. Is that under iDVD somewhere?

Also, I have iDVD 6 and the pro setting for encoding isn't an option. It seems that best quality will probably work best for this project as it is longer. I saved the disc image and it looked better than when I had it on best performance. Do you know if Toast is a better program to burn with?

Also, I have several smaller videos. The longest is thirty minutes and I think the average is about fifteen. Does the video playback rule (number 2 on your list) pertain to the total video playback or each video? I'm using a dual layer dvd so I thought that help with the encoding/motion blur problem. Would you suggest taking off some of the videos and burning it to a separate dvd?

Thanks.

You may want to post your question to the iDvd6 Forum as well since iDvd'08 is significantly different from all earlier versions of this app. That and we really make every effort on these Forums to keep troubleshooting categorized by application and version number so folks don't get confused.


Keep in mind that in earlier versions of iDvd6 you will need to lower the burn speed thru either Roxio Toast (which is what I prefer) or apple's disc utility (the option to lower the speed becomes available after hitting the burn button).


Also iDvd 6 only allows for 2 encoding options (not 3) namely Best Quality and Best Performance. Only iDvd'08 offers the 3rd option or Pro settings as well.


Hope this helps and please remember in the future to post in the appropriate forum for the most accurate responses to your question/s.


Good luck.
