That does t work unless you hack the registry too so Vegas looks up both ac3 folders. that is the reason you to rename it.

Thanks Oldsmoke.  I am just leave it then.  I don't care for ac3 studio.  I got ac3 pro working  and I am happy with that.

what is the registry key, I searched but couldn't find it.

There are many, not an easy task to get that done. I worked on it for a while but I dont have time to complete it.

Registry: There are many instances of ac3plug in vp13 if these can be replicated in vp14 all well & good.  Not found any instances of ac3plug.dll.  Unless a '.reg ' working file is published there will be a load of corrupt registry files around.

Please make sure you have a good image/backup of your system disk before experimenting.

Can anyone tell me if the MAGIX VEGAS Pro 13.0 builds 543 and 545 had the AC-3 Pro encoder?

An excellent question. Can someone please answer?

There is no download for DVDA 6 from Magix only VP13 is new branded

Can anyone tell me if the MAGIX VEGAS Pro 13.0 builds 543 and 545 had the AC-3 Pro encoder?

Never tried that, since the last SCS version is still fine.

AC3 Pro still present in VP13 build 543.

Hi Nick,

ac3 Pro and ac3 Studio are both available in MVP13 build 545.

Best Regards......George

Vegas Creative Software really needs to explain the reasons behind this decision ?

I downloaded the trial for Premiere Pro, and it includes Dolby Digital (Pro) and Dolby Digital Plus.
It doesn't say specifically Dolby Digital Pro, but it does include 95% of the same controls/config that VP13 has on offer for AC-3 Pro encoding.

Dolby Digital Plus appears to be next generation above Pro, going by Dolby's comparison chart here.

There is some irony about all this. Adobe dropped support for their disc creation software Encore when CC was released, but inside of Premier Pro they are offering latest technology for AC-3 Audio encoding. Vegas Creative Software is continuing support for DVD Architect Pro, yet has gone backwards in Vegas Pro for encoding options related to disc creation. What should have actually happened and would have increased tremendous confidence amongst all Vegas users, is the addition of Dolby Digital Plus as well as maintaining Pro. Hopefully they may consider doing this in VP15, if they want to stay competitive with Adobe Premiere Pro. I would pay for this if it was there!

As far as I see here, the trick to transfer the AC3 Pro encoder seems to work also with the DVDA 6 b 237 to DVDA 7.

I use only DVDA 5.2 build 131 and it works for me.

The funny point is: I have rendered a short test event to both AC3 Studio and AC3 Pro. Imported that in DVDA7. And looking at optimise I see that none of the two files seems to be re-encoded by DVDA 7 (so optimize is fine with both streams in DVDA7).

have you tried a Blu-ray Disc?

Right. The output of AC3 studio encoder is recompressed for Blu-ray, while the output of AC3 Pro stays uncompressed for Blu-ray.

So, what is funny or new?

It remains, AC-3 Pro is still required for Blu-rays when DVDA should not recompress.

The file size and MediaInfo reports for 192kbps AC-3 Studio and Pro renders are identical. I'm thinking there may be some flag or metadata in the Pro render that certifies it as encoded by the official Dolby encoder. And perhaps the Blu-ray spec is more strict than DVD about that. Just a guess.

It remains, AC-3 Pro is still required for Blu-rays when DVDA should not recompress.

True, but it is also true that the AC3 Pro Plugin used in DVDA 6 (and also 5.2) can be used in DVDA7.

True, but it is also true that the AC3 Pro Plugin used in DVDA 6 (and also 5.2) can be used in DVDA7.

AC3 Pro plugin can't be used in DVDA7. When I try to create a disc which need audio reencoding, I end up with an error.

2- Another test: after creating a disc (Blu-Ray) with reencoded audio from DVDA7, I then unmux one of the "m2ts" file created and reimport it in DVDA7. And the audio still needs to be reencoded even though it has already been encoded by this software... It seems that DVDA7 definitely can't be used for creating compliant Blu-Ray disc.

I have no problems (just a short test file)
where is your ac-3 pro plugin exactly?
How do create the files for DVDA?
For Blu-ray you need

1. a video stream (mpeg 2 or avc)
2. an audio stream (ac-3 pro)

then there is no need to recompress
how did you unmux the m2ts file?

I actually use ac3studio in Vegas to encode the audio and mpeg 2 for the video.

Import in DVDA, create ISO file (with audio rencoded by DVDA7).

Then use Winrar to open the iso file, extract the m2ts file created, unmux with TSmuxer and import both files (audio+video) in DVDA7. When I create the ISO, the audio still need to be reencoded.

 That's why DVDA7 doen't create compliant bluray file.
