Thank you Jeff.
I used the defaults and it built the image just fine.

hi Jeff,

I’ve read about the HD2SD workflow process recently, but have not tried it out. If you don’t mind, please send it to kissupandu@yahoo.com.
I capture using MAtrox to MAtrox MPEG-2 I-frame HD AVI files.

Thanks
Nanda

hi Jeff,

1 – yes that was intentional to encode to Matrox H.264 1080p 23.98, I think it was because I liked that look better for some clips. If you have any recommendations on why this need not be done or should not be done, please share. This has always been my workflow. Capture to 1080i 29.97 Matrox AVI, export to H.264 23.98, import to Encore, build/burn. Maybe I will try to encode to Matrox H.264 1080i 29.97.

2 – I just remembered that I had ‘filled up’ another bluray disk w/ a 22.xGB image size and it was not the bitrate that did this, but the duration, while keeping the bitrate default of either 25 (4.1) or 15 (4.0) in the Matrox preset.

3. When I tried to build image using the 40MBps bit rate Matrox H.264 video file, after importing the file, Encore threw an error that the bitrate of the file exceeds the bluray spec – like you said. So, I guess the practical limit is lower than the theoretical limit. Although I recall being able to go up to 30-35Mbps.

Lastly my q was more about why the image file size REDUCED to 3.86GB, when I simply increased the bitrate to 40Mbps in Transcode Settings, but went back to 15.xGB when I reverted to default Transcode Settings of 15Mbps or 25Mbps.

I would expect then that Encore CS6 to not give the option of a 40MBps bit rate in the Project Settings or Default Transcode Settings.

thank you again for your prompt reply.

hi Jeff,

I ran into a very similar or nearly identical issue and found this thread. I hope you will be able to comment on it as reading through the thread did not give me any clues.

I exported a 1hr17min HD clip (Matrox AVI 1080i 29.97) from CS6 to a MAtrox H.264 1080p 23.98fps, with
– using 40Mbps bitrate for video,
– 16bit audio
and the resulting
– H.264 video file was 22.xGB
– and the audio was ~800MB

I
– imported these into Encore CS6 as a timeline
– right clicked on each file, then Locate Transcoded File, selected the same files from the file system.
– left Blu-ray Transcode settings as Automatic (which means use Project Defaults)
– verified Check Project successfully (no errors)

When I go to build a disc image, it shows 15.6GB image size!

My project settings have default transcode settings for bluray set to use 40Mbps for video (H.264).

So I did Revert to Original action on the .264 video file, went into Transcode Settings, changed the Quality Preset Settings for Matrox H.264 1080 23.98fps to use 40Mbps bitrate, saved the changes and when I re-locate transcoded file and do a build image, the image size is 3.86GB!!

I normally don’t change the bitrate during export from AME or from CS6, when exporting to H.264 – but this time I did as I wanted to use as much of the bluray disc as possible.

Is Encore CS6 limiting the size of the image??

Errol,

I may be late in this response, but hope this helps.
Files 2GB or larger will cause Encore CS5 to ‘hang’ or become very slow during import or drag and drop to the timeline – I found this to be a known issue/bug on the Adobe site, but cannot find a link to it now. If you split the files to < 2GB parts and then import them, it will work somewhat better – but it will still be slow.
