https://forums.adobe.com/people/Guy+Burns wrote In my experience with Encore, when I butt clips against each other and Build to Blu-ray, the end of each clip seems to pause for maybe 0.25 seconds before going onto the next clip. In my testing, all clips were rendered out of Premiere as m4v and wav files, in legal Blu-ray format, such that Encore reports them as Don't Transcode. The clips I've tested come from a variety of sources, but are mainly old TV ads, movie trailers, shorts and cartoons. They could be NTSC or PAL, interlaced or progressive, but all are rendered as 1920 x 1080, 23.976 fps. In what follows: Cut means the outgoing clip shows full-brightness images right till the end of the clip Fade means the clip fades to black in one second, right at the end of the clip Black means the final 0.5 second of the clip is black. Here is what I've found: Multiple clips on a single timeline when played in Encore – no problems. Multiple clips on a single timeline when Built to Blu-ray – Cut and Fade clips show the pause problem. Fade clips seems to pause at about half brightness, whereas Cut clips pause on the last frame. Black clips don't have the pause problem. The pause problem occurs when I build to a folder and play that from a fast USB stick, and also when built to a Blu-ray disk. Reassembling the clips one at a time onto separate timelines, and then generating a Playlist, has the same result as above. The problem does not occur if I extract the m2ts files from the Blu-ray, open them in VLC, and play them automatically in sequence. Similarly, if I Join the extracted m2ts files using tsmuxer, and play the new file in VLC, there is no pause problem. Similarly, if I use tsmuxer to multiplex the original m4v and wav files (directly out of Premiere) into m2ts, then Join, then assemble in VLC, again no problem. Ques 1 Is it possible to fix this pause problem, or is it inherent in Blu-ray? Ques 2 Is it likely that the problem is due to the types of clips I'm using? Would the problem disappear if tried stills that Fade? Ques 3 Making the final 0.5 seconds of a clip black, fixes the problem. Would a shorter time work? Ques 4 Although I've been testing on material that's not my own, my real interest in all of this will be when I produce my own Blu-rays. Based on advice I read from experienced users of Premiere, I generated my projects in a number of Sequences. I assumed that I would then render each Sequence, and have the Blu-ray authoring program join them together seamlessly. But it appears I may be mistaken; that doing so will not work properly; that Blu-ray cannot play a series of m2ts files without a pause between them. When professionals produce a feature film on Blu-ray, do they ever do so in small sections? Or are films always rendered as one big file when it's time to go to Blu-ray? Thanks in advance for any comments. Question 1: Yes - do not do this. Assemble all your assets before authoring, and remember that Authoring is just that - it is not editing, and you simply should not butt clips up against each other. If you must do this then do it in Premiere, render the Elementary Streams & use those for authoring. Treat Encore as an assembly tool, and not an editor. Question 2 No - the problem is trying to edit in Encore. Question 4 Each sequence should be rendered out and thought of as the actual playlist - not part of a playlist. If I am putting a disc together with a 2 hour video film, then the whole film goes into one sequence and gets spit out as a .264 file with separate audio files. If you need to join 2 or more clips together then do it, but make sure each sequence is complete & self contained. Films are always rendered as one large file. Blu-ray is complicated, and you will need to forget everything you know about DVD as it is no longer relevant. If you want to start doing commercial titles then there are some gotchas: 1 - AACS is mandatory so you will need a tool capable of outputting at the least a Type A BDCMF file with AACS flags set. 2 - Your clients will need an AACS content owners license 3 - You cannot create BD-R titles using written media & sell them as Blu-ray discs as these are non compliant products and if they find out about it Sony will order all copies destroyed if they carry the Blu-ray logo - however you can sell as BD-ROM finalized as BDMV. 4 - the biggest one of them all - what authoring package to use. There used to be 3 tools available that would handle replica content in one package - Encore cannot output Blu-ray replication masters without a plugin and I am not sure this is even still available any longer A - NetBlender's DoStudio was bought by Sony Creative Software & has been shut down now. B - Sony's own Blu-Print has been shut down C - Sony Creative Software no longer exists - all assets have been sold to Magix except DoStudio & Blu-Print, and DVD-Architect & Vegas cannot produce replica output masters D - Scenarist is still viable, still developed & still supported but it is £60,000 per seat plus annual support fees.
