Creating Blu-ray Disks

[RoccoP]

I have a high definition video camera that records to Digital Video tape. Using my iee1394 connection (firewire) I copied the files to my PC. Each tape created a file approximately 11.5 GB in size.

Now here is my question When I try to create a Blu-ray disk with Roxio 2009 it converts the files so that their size goes down about 50%.

So I figured I would use Nero that came with my recordable Blu-ray drive. When it creates the files they increase in size by about 33% so the files are 1.8 GB in size.

So my question is what gives. I figured at the best quality I would be able to get 2 tapes on at about 23GB in size so a 25GB Blu-ray would be perfect.

 

With Roxio 2009 I can fit 4 videos and with Nero only 1. What is going on here. I am new at this so any advice will be appreciated.

You are thinking way too hard and looking at numbers that have no meaning in the end…

 

Burn! Then compare the results.

 

Don't convert anything. Add the files to VideoWave, save a VW Project. Then open a New BD Project in MyDVD and add the VW Project.

 

Video work has always been based on time. File size is a useless measure… By your thinking you could make an Audio CD of 240, 3.5Mb mp3 files! But an Audio CD only holds 80 Minutes so you only get 20 of those songs on it…

 

Think Time

How much fits on 25GB Bluray disc also depends on the codec used. The Bluray standard uses MPEG 2 or AVCHD. MyDVD can now smart render MPEG 2 HD and AVCHD. But I think you need to have the Project settings close to the input first. Here is what MyDVD supports:

HQ 1920x1080p

SP 1920X1080i

LP 1440x1080i

EP 1280X720p

 

The above resolutions can use MPEG 2 or AVCHD. So if you are using HDV on tape, you should set MyDVD to LP with MPEG 2 because that is what HDV uses. MyDVD should not re-render the files except where you have done editing (transitions, effect, etc.).

 

 

Thanks for your help. I will check this out. I believe the source material was 1440x1080i. I will try to create it with those settings

HDV camcorder? Those use MPEG 2 HD 1440X1080i. If you burn to AVCHD to standard DVD, the files will have to be converted to AVCHD. If the files are already AVCHD, then processing will be faster.
