I am attempting to burn a 3 hour+ movie that I created on Premiere Pro CC to Blu-ray. However, during my final build on Encore, I continue to receive errors that have to do with audio bitrate underflow problems. I experienced this issue during several test runs and fixed it by changing certain settings in my project to (automatic), but on this final build, it's failing again. Let me provide all the relevant details below for context. BTW, it's worth noting that one month ago I had never so much as used Adobe or created a DVD of any sort. I am on multiple concurrent learning curves.
SET-UP: I have all the right equipment. I’m using Adobe Premiere Pro CC with Adobe Encore CS6. I’ve purchased a professional grade Blu-ray DVD burner and have installed all the correct drivers on my Macbook Pro. The problem lives somewhere in the realm of either A) how I’m encoding my movie files from Premiere Pro or more likely B) My setting for burning the entire DVD project to the disc.
ENCODING MY MOVIE FILES:
- The final movie file that I’m exporting is just over 3 hours in length.
- I’m saving the movie file with the following settings:
- H.264 Blu-ray format
- I’m using custom settings to export both the video and audio to maximize the quality (both my input and output source settings do match)
- VIDEO: 1920x1080 aspect ratio, 29.97 fps frame rate, NTSC TV standard, Level 4.1, Bitrate encoding is VBR-1 pass, target bitrate setting is 30 Mbps and max bitrate is 35 mbps. I’ve also set it for maximum render quality.
- AUDIO: PCM, 48kHz speed, stereo, sample size is 16 bit
- It took about 12-13 hours to encode these files. The .m4v video file is 41.25 GB and the .wav audio file is 2.12 GB.
- I saved these directly to my 250 GB internal hard-drive to allow for the fastest burning to DVD possible and intend to move them to an external hard-drive once I’ve created the media for the client.
- I know these files work because when I import them as assets into Adobe Encore to build the DVD, the assets render correctly (although it does take several minutes for Encore to “import" the 41.25 GB.
BURNING THE BLU-RAY:
- My final Blu-ray project includes just two menus and one timeline that I created in Encore. The assets that I imported are 2 WAV audio files, which are the songs overlaying my DVD menus (about 80 MBs each). Lastly and most importantly, it includes the audio and video files that I created with Premiere Pro.
- During numerous test efforts to create a Blu-ray image (with smaller files), I continually received an error stating something about too high of a “bitrate underflow” with my audio files. The fix was to make sure that I changed the Blu-ray transcode setting to Automatic (originally it said "Don’t Transcode”). Because of how I created the video file, I was able to leave that on “Don’t Transcode.”)
- However, when it came time for my moment of truth — burning this entire project to Blu-ray DVD — it’s been one epic fail after another.
- These are my settings on the project build screen for Encore:
- First of all, the project does Check out — there are no errors in its construction.
- Format: Blu-ray / Output Blu-ray Disc (or image … it failed for both) / Source: Current Project / Destination is either DVD burner or folder on my computer / The entire project is 45.72 GB. (I’m attempting to burn this on a Verbatim BD-R DL 50 GB blank disc (5 of which I’ve already wasted).
I’ve spent hours researching every step and I’m coming up with nothing. And because Blu-ray is already an antiquated technology, all my local contacts are telling me that they’re delivering products digitally now. So I’m at a loss. PLEASE HELP ;-)
