AVCHD to BLU RAY with vegas 8 and DVDA 5?

[John Rofrano]

The rule of thumb is to choose the settings that are closest to your source. In your case, option 2) Blu-ray 1920-1080 50i 16Mbps is the one to render to in Vegas. Then when you create your Blu-ray project in DVD Architect 5, select AVC 1920×1080-50i, 16:9 since you’re already working with 1920×1080 AVCHD footage. It won’t hurt to use other settings but sticking with the format you are using makes things simpler.

Thanks for your answer!!!

I see your point but for my information:

Is there an difference between quality of option 1 or 2 from vegas 8?
What i mean :
Option 1 is an template who says :video format=mpeg2 25mbps
Option 2 is an template who says :video format=AVC 16mbps

I know my source is only 15 Mbps so that doesn’t matter but what about the codec’s
Which is better from AVCHD to: AVC or MPEG2 or is it the same codec with an another name???

I hope you can explain it to me!!

I guess the easiest way to explain is that AVC is more advanced, and can carry the same quality as mpeg2 but with a lower bitrate. So just because AVC is at 16mbps and MPEG2 is 25mbps, doesn’t mean that mpeg2 is better. AVC is already what you’re recording in, and will allow you to fit more data on each disc, so there’s no real advantage to convert it to mpeg2.

Thanks again for your time to explain it to me!!

So you say that AVC = AVCHD = format/codec from camcorder??
Sorry for the silly question then but why does Vegas 8 have templates for render to Blu-ray .avc extension and AVCHD .mt2s extension when it is the same??( i know that avc is only video and avchd is video and sound but is that the only difference??)

Oke last question and then i am a happy man:

When i in DVDA 5 have made a blu-ray disc(i.e AVC) and after that i want to use the same compilation for a normal dvd. Can i simple change the properties of the project to DVD and then “Prepare disk” again?
Does DVDA5 do all the right encoding to normal mpeg2 or must i do it myself in vegas all over and make an another compilation to make a normal video-dvd??

Thanks in advance!!!!

Almost… not all AVC is HD. You would also use the AVC to make MPEG4 files for Sony PSP, etc. But in your case, the AVC that you have is AVCHD.

Mostly. The Blu-ray template makes an elemental stream (video only) which is all ready for authoring and the AVCHD makes a transport stream of both audio and video.

It should do all of the re-encoding and make a regular DVD. I have been tempted to try this but haven’t yet. I have changed the project from Blu-ray to DVD and reused all of the menus and just substituted MPEG-2 files that I created in Vegas but next time I will try it this way and see. Sure seems like a lot less work than what I was doing.

thank you very much for your information!

I’ll will try the avc encoding.
I hope dvda will encoding it also to a dvd. May the testing begin……

[Michel Van nistelrooij]

Oke i have upgraded my computer with some memory and i’m testing with the AVC templates

2) Sony avc Blu-ray 1920-1080 50i 16Mbps(makes a .AVC extension)
3) Sony avc AVCHD 1920-1080 PAL 16Mbps (makes a .m2ts extension)

Still i have one question:

When i look into the templates of Vegas( button custom and then the settings of the template) , i see 1 difference between the two templates( except that 1 is with audio and the other format not)

Template 2 uses profile: Main
Template 3 uses profile: High

I have a Sony TG3, so can someone explain me what is the best template i can use???
What is the difference between profile main and high??
Quality or other decoding format???

I hope someone knows the answer!!
Thanks again!!

[John Rofrano]

I believe they will both give you the same video quality. I would use the AVCHD template because it includes audio and therefore is one less step in the process. You might want to try both and see if you can see a difference in video quality but I would bet that you can’t.
