Premiere Dynamic Link vs Export to Encore, and bitrate calculator qs?
My June 22 thread q in the subject line was answered by Stan Jones. But, Jeff Pulera generously answered my other qs embedded in the body. This new thread is a response to Jeff’s advice in that part of my June 22 thread.At this point, it’s my goal to produce the highest resolution a/v possible on a 25GB BD-R, disregarding the time it takes.
My first attempt as stated in the June 22 thread: Premiere Pro CS5.5.2 project to Encore CS5.1: Adobe Dynamic Link > Send to Encore > New Project dialog: Settings: Authoring Mode: Blu-ray > Default Transcode Settings… Automatic Transcoding: Max A/V Bitrate 40.0 Mbps >Video Transcoding: Codec H.264; Dimensions 1920x1080 (what I want); Frame Rate 29.97 (selecting 59.97 reduces the dimensions to 1440x1080); Audio Transcoding Scheme Dolby Digital. On Encore’s Project panel, two files appeared, Types: Timeline and Premiere Pro Sequence. I created no menus. On the Timeline panel, the prproj End Action is Stop, Duration is 00;59;58;14.Menu Remote is Return to Last Menu. Chapter 1 (the only chapter) Link is Not Set. Properties panel, In and Poster are all zeros, End Action is Not Set. I burned a BD-R disc at Write Speed 8x (2 hours to transcode). Playedback on two players without any issue.
Jeff’s response, if I understood correctly:
In Premiere, File > Export > Media… > Export Settings dialog Format: H.264 Blu-ray > Video Bitrate Settings (to determine the settings, use DVD-HQ : Bitrate & GOP calculator [see * below])> Audio tab, Audio Format Dolby Digital, 192kbps > Source Range: Entire Sequence > Export. Audio and video exported as separate files with extensions m4v and ac3 (took 1hr 15mins). File > Close Project.In Encore, New Project dialog > type Name > OK > rightclick Project panel > Import As > Timeline… > navigate to and select the audio and video clips together > Open. Encore “Stopped responding” at 25% encoding for ac3 file. Why? Tried solutions offered in Ronald’s June 24 thread, but to no avail.
* DVD-HQ : Bitrate & GOP calculator settings::
Source length 60 minutes. Video format NTSC. Audio format Custom 640 kb/s. I chose this number because Wikipedia stated that Blu-ray Disc can output an AC-3 signal at a full 640 kbit/s. Audio streams 3. Chose this number because I have a stereo track and a 5.1 track that link to the video, and a stereo wav/m4a music track. Rate control Automatic. Scene motion Heavy or mixed. Scene detection Active. Bitrate limit BD (48 Mb/s).Media size BD SL (23.28 GiB). Other assets 0 MiB.
Results:Status OK. Rate control CBR. Bitrate, max, av, min 44700 kb/s. 42100 kb/s if Audio format is 1536 kb/s (DVD PCM). 29500 if bitrate limit is 35 Mb/s. 32100 if bitrate limit is 35 and audio format is 640.
GOP structure and limit. The instructions seem to indicate that for BD i should use the decoder’s defaults. Size (approx) Video 19644 MiB, Audio 824 MiB, Remaining 3372 MiB. Does this mean I can almost max out a BD disc with one hour of a/v, or have I inputted incorrect data in the settings?
If the calculator calculates best bitrate setting to be 44.7, but Jeff advises to stay away from 40.0, 25-30 being more appropriate, do I have a quandary, or have I inputted incorrect data in the settings, or misunderstood something? Thanks for all your help, Don
