Also, what KIND of file are you using?

2. Re: Timeline audio cut short
SAFEHARBOR11 Nov 16, 2012 9:15 AM (in response to John T Smith)Saw a similar posting the other day and the issue turned out to be that the source clip was a multiplexed .mpeg clip. Ideally, you want the audio clip separate from the video, so typically an .m2v video and .wav audio file. Please let us know the workflow you are using
Thanks

seiurus Nov 16, 2012 9:57 AM (in response to SAFEHARBOR11)Yes, it's true. I have exactly an mpeg multiplexed clip, but isn't that what you want, to avoid having to fiddle around with audio sync, etc? Separating the audio and video does work, but seems kind of "primitive".

4. Re: Timeline audio cut short
John T Smith Nov 16, 2012 10:17 AM (in response to seiurus)You export out of PPro as MPEG2 DVD - note the DVD part!
That creates what Encore wants... a video file and associated audio file
When you give Encore a MUXED file, with video and audio in the same file, Encore must DE-mux to have two separate data streams... and Encore sometimes "struggles" with that
Do as Jeff said, export from PPro to MPEG2 DVD, and try again

SAFEHARBOR11 Nov 16, 2012 12:53 PM (in response to seiurus)Hi Steve,
By default, Encore is set up to take your .wav file and convert, or "transcode", to Dolby AC-3. Therefore, you don't want your audio pre-compressed and mixed with the video. Give Encore the .m2v video clip, and that is ready for disc and will not be transcoded any further, and the uncompressed, high-quality .wav audio gets turned into Dolby, and everyone is happy ;-)
As John pointed out, you are creating extra work for Encore by feeding it a muxed file, since it has to pull apart the (already compressed) audio and video, and then re-compress the audio AGAIN, so losing quality there as well as increasing build time.
Nothing primitive about it, you're providing Encore with a "ready to go" video clip and a "ready to transcode, high quality uncompressed" audio source. Note that if you have Adobe Media Encoder CS6, look under the AUDIO tab and you will find a "Dolby" option and can in that case export the .ac3 file right along with the .m2v and then they are BOTH ready for Encore, no transcoding then in Encore.
Regarding sync, if you output the Premiere sequence as MPEG-2 video, and there is no corruption/glitch in the file (there should never be), and you do the same for the audio, they will ALWAYS sync perfectly. These are DIGITAL files we are talkng about. Unless your software is broken, no worries, it is designed to work this way. Heck, sometimes I export an .avi from Premiere and encode to MPEG-2 using 3rd-party freeware (with no audio) and then I just export a straight .wav out of Premiere and marry the two files together in Encore...no prob!
