iDVD bad deinterlacing or wrong DVD norm handling?

Hello,


I asked someone to look at two files that I created with iDVD out of the same source.

One was 3000kbps, the other was 5900kbps (iDVD seems to never use a higher bitrate!)


He said, that the bitrates are still enough to avoid to harsh artefacts. However he said, it looks as if bad deinterlacing or even a bad handling of the norm (PAL DVD) was done.


COULD IT BE THAT iDVD is not good at that or, that because it is an American App, it maybe doesn't handle PAL that well?


Here are the two iDVD encodes, if you care to have a look https://www.wetransfer.com/downloads/02aae2e65d04775a7c16a0707005743a20160119171 248/3fd95dd4642f954e992310e2b7c0383920160119171248/7b0040


This is the original source (h.264) http://www.jottacloud.com/p/eichhoernchen/209b5ff1056f47f2a380d9a958180012

and what Toast did of it (setting custom, half-pel, 7-8.5mbps, audio 448kbps, progressive) http://www.jottacloud.com/p/eichhoernchen/94007a89aa0a469d898ae91d208e0164


(side note: Toast, too won't use a higher bitrate than 5700kbps for this cartoon, however I could get Toast to use 8mbps when I had it convert a HD-movie to DVD-video. While iDVD even uses 5900kbps, when given HD-content).

Any input?


The question about deinterlacing issues and ghosting aside.


Can someone see which of the linked files look better/best?


iDVD (3045kbps professional quality): http://www.jottacloud.com/p/eichhoernchen/3a14073435cf41b3bdf3c65756ac133b

iDVD (5900kbps professional quality, maximum iDVD will use with the given source file): http://www.jottacloud.com/p/eichhoernchen/b0d2f168ac4841958d51595712fc4922

Toast-8 (5700kbps, maximum bitrate that Toast uses for the material): https://www.jottacloud.com/p/eichhoernchen/94007a89aa0a469d898ae91d208e0164


Thanks!

Thanks, but no matter, if I choose interlace or progressive in Toast OR choose deinterlacing in the DVD-player-App in OS X (as the help atricle sugguests) it is still there. Also, it seems it is not really interlacing error, but something different. Looks different. I guess it is error that come from converting NTSC to PAL.


I decided to live with it. If it has to do with deinterlacing, the help desk article says that it will disappear on TV (not sure, if they are only talking about Tubes and not LCD-TV-Flatscreens, but anyway... I am now just trying to find the right bitrate.
