Anamorphic destination or not?
 
If source is anamorphic should destination also be anamorphic?
eg. opened source in moviestacker & "anamorphic" for source automaticly check marks the box, But in this case do i manually also have to select anamorphic for destination aswell?

It depends if you want to do an anamorphic DVD or not.
If you don't and want to compress better, although loosing the anamorph target, then deselect anamorph destination.

Thanks kwag ... If I dont do anamorphic destination with this source then the blck bars on the top & botom are wider than the movie part :D

Actually, if you target non-anamorphic from an anamorphic source, you should get larger black bars top and bottom, because the film pixel area will be fixed to a smaller area.
Then when you playback on your SAP, you'll probably need the "zoom" adjustment on your TV to correctly display the proper aspect ratio.

Which is not good, since the upscaling done by the SAP will never give you the same quality levels, if you chose to encode anamorphic originally.

Exactly :)
Only do non-anamorphic targets if you really want to cram up more space on your target DVD.
In my case, if I do non-anamorphic targets, I can see them perfectly on my 4:3 HDTV without any need of adjustment.
This way I can easily fit about 4 movies on my KDVDs, and the result is excelent.
If I had done anamorphic target, then I could only fit 3 movies ;)
It all depends on your SAP/TV combination.

Hi Kwag,

What max/min bitrates + CQ factor do you use when you encode anamorphic with 3 movies and what Max/min Bitrates + CQ factor do you suggest, lets say, If I have to encode anamorphic with 2 movies and AC3 sound in one DVD.

The easy way is CQMatic.
I think that with 3 movies, the sound isn't ac3 but mp2.

To be more precise, the main question is not the format but the bitrate. If AC3 means 5.1 at 384 kbps then yes, for 3 movie you can't use that. You have to use 112 or 128, and for this it is better to use mp2.

hmmm, but does it calculate based on two movies + AC3 sound and I wanted to reap the benefits of his experience than some calculation done by a software. ;)

Any experienced people will give you the same answer : your question don't have any answer.

Each source is different and you can't bet what will be the CQ.
For the bitrate, this is a little different and for 3 movies you can use 4500 for max as a good value. But some film won't be good below 6000, and it's better to put 2 on a DVD and not 3.

Well thanks, this is also by experience, otherwise you would have told me to use CQmatic ;)

You are right, I wanted to say that, but your explanation is better than mine one.
BTW, the previous quoted text is mine not supermule's one (compare with your quoted post).

Maybe you don't understood me or me don't understood you.
You can't fit several movies in 1 DVD without doing some calculation.
So it is for that that I recommend you CQMatic, that is the easy way. Also it is the classic method.
My personal taste is 2 movies in one DVD, so doesn't matter really what will be the final bitrate, as there is enough to obtain excelent quality for each movie, whatever be the length of them.
Also a thing is maxbitrate, that Dialhot pointed you and another the avgbitrate. The final quality is related with this one also.
The modern method is, IMHO, to use ProCalc Lite. I called its job as Avalilable Space Proportional Allocation (ASPA). If you want to put 2 or more movies in 1 DVD, it calculates proportional space related to their (streams) complexity, and give you the proportional space to each one of the streams. Also gives you the necessary avg bitrate, so you can encode your streams with any encoder that you want.
ProCalc lite and ASPA don't have here a general consensus yet. But you can follow news in its own thread.
I do use ProCalc Lite and ASPA method in all my backups.

Thanks Prodater, I will try to use this tool.
