Not when you have a 40GB on your laptop with win2000 installed on it of course

Else, no it is not important WHEN YOU ARE AWARE OF THE PROBLEM ! That is the purpose of the forum also, to warn people. Because manual D2S never mention it needs so much space.

EDIT: and I hadn't see Zyphon's post yet
Note: Zyphon you can still work from the DVD with AnyDVD installed but it is not recommanded (for your drive safe).

40gb, r u sure ?

4 - 8 gb rip
upto 5 sample tests - 40 to 60 mb each
final encode.
audio ripped 500mb
then dont do the multiplex (.bat trick in multiplexxer settings)
import the files into dvd lab pro
compile.. (by this time u can have deleted the main ripped vobs)
another 4 gb (but minus the deleted vobs)

how do you work out 40

with diko - i experienced too much trouble.. n its not very much customizable for my liking, dvd2svcd kicks ass for beginner or advanced imho.
alternative:
check "no images" in cd image tab.
open the notepad and write:
@ rem
save as "RunBBMPEG.bat" and put in the bbmpeg folder under d2s
choose that "RunBBMPEG.bat" in the multiplexer tab.
check "don't delete any files" in misc. tab.
encode as normal(choose the kvcd notch)
you will get:
6-8Gb for the source ripp
4.37 GB for the video and audio elementary streams
you will need less then 13gb do do the whole job
here you can delete the 6-8Gb for the source ripp!

after the CCE encode take the encoded video file(or puldown encoded file ntsc).mpv and the .ac3 and author in tmpgencdvdauthor(or other authoring program)

plus 4 gb if you used pulldown (as you mentioned just under).

I also forgot this part in my list posted above and that give a total of 34 GB if you let D2SRoba works alone.

right
6-8Gb for the source ripp ,
4.37 GB for the video and audio elementary streams and
plus 4 gb if you used pulldown
....then needed round 16.5Gb!

Thanks for the info Phil.

As it happens I did have to buy AnyDVD because ages ago I purchased CloneDVD to back up my DVD's until I turned to DVDShrink.

Hopefully now though Sansgrip tool will eliminate both.

Hey Guys.

Now, I've made a DVD with a res. of 352x576 in 16:9 but the DVD-Player doesn't read this flag and there aren't any borders. First I have put the Video, after patching in 4:3 because TMPGEnc DVD Author can't read this res. in 16:9, and after authoring I repatched the files to 16:9. But Now, the DVD-Player see it as a 4:3 movie.

What I've done wrong?

Hope you can help.

Or isn't a res of 352x576 anamorph compatible?

You can't encode 352x at 16:9 for DVD target
It's out of DVD specs. You must encode 4:3

I've one another question to the spec.

At the moment I encode with HC Encoder and want to use only one B-Frame because the quality is a little bit better and this gives me more compression. In the past, I also make my ONE-CD-Encodes with TMPGEnc with only one B-Frame and the results are very, very good and this SVCDs and VCDs were played very well on my SAP.

Now, my question:

Are one B-Frames allowed in a DVD-Stream? Or is the only limitation the lengh of a GOP?

Hope you can help me.

I don't see any reason why it wouldn't be compliant.

I can't see how setting 1 B frame can compress more than setting 2 B frames

Like in the PM. In my tests 1-B-Frame gives me more compression and it looks in high motion scenes better as 2-B-Frames. But I test again and post my results.

But you say it's dvd-compliant?

Another test with HCE and CQ:

1-B-Frame(s) - 85.671Kb; ~0,49x% more compression
2-B-Frame(s) - 86.177Kb;

1-B-Frame(s) - 100.434Kb; ~0,79x% more compression
2-B-Frame(s) - 101.222Kb;


Today, I post also my results with TMPGEnc's CQ mode.

What is the actual GOP structure in all those cases? VirtualDubMod will show it properly.

Can you explain this? I don't understand, what you mean.

It's a GOP of 15 Frames and in one example 2 B-Frames between the Ps and one with only one B-Frame between the P's, or what you mean?

Exactly. What it is like in the encoded file - is it really IPBPBPB... or something else?

Yes, it is.

IPBPBPBPBPBPBPB is my GOP and have more compression then the same with 2 B-Frames. I've tested it also with TMPGEnc again and it is more then 2% more compression.

But I have a problem with my TMPGEnc, hope you can help and test it on your systems.

If I set my GOP to "1-5-1-1-15" I only get a GOP of 12
If I set my GOP to "1-14-1-1-15" Then I get a GOP of 16

I can't get a GOP of 15 with TMPGenc 2.520.xx. Only I set to "1-16-1-1-16" and then switch ClosedGOPs on then I get 15 Frames.

Do you have the same Problems with 15 Frames? With 18 it works.

EDIT: With 1-B-Frame only (sorry don't know the word) values like 12, 14, or 18 are possible. With 2-B's only 13, 15, 17 etc. are possible. With the option closed GOP all values are possible.

Sorry, but it just doesn't work that way.
If you do a 2-pass encode, which guarantees an accurate file size, you'll see that at lower bitrates the 2 B frames clip will look far better that 1 B frame.
As you go higher in bitrate, the opposite occurs, and you'll get a sharper picture with less B frames.
If you can afford even higher bitrates (>~10Mbps), IP GOP will be better than IBBP, and if you can afford >~50Mbps, then I frame only GOP is the best
You're obviously using CQ mode, and the encoder will compensate for frame (GOP) length.

Sure. IBP or IBBP is DVD compliant.

For me my 1-B-Frame encodes looks great and they have less blocks then the 2-B-Frames. They looks also better in high motion scenes because there is 1-B-Frame better.
Here some pic from my TMPGEnc test with 1, 2 and 3-B-Frames:




The GOP are:

1-20-3-1-0
1-27-2-1-0
and
1-41-1-1-0 (from inc.)

The compression of one b-Frame is much better.

If you say this then 1-B-Frame would be the best choise for CQ mode in every encoder. But the quality looks also better with HCE 2pass.

Sure. IBP or IBBP is DVD compliant.
This is what I actually want.
