Encore: Bluray Project Flicks At Menu Loop Point

Hello,

I have created a Bluray menu for a project, and I have used a video with a loop point

as my menu with a fade in/ fade out, so that it is more aesthetically pleasing.

Everything is good in the encore preview, however, upon building a bluray folder, I can

see that both at the loop point of the video menu and when it changes to my transition,

the screen flicks/ jumps. Is there any way to stop this from happening? I understand

Encore is no longer supported.

Thanks.

I am working on a project and experiencing this issue. Thanks Stan Jones​ for pointing me to this thread.

I tried what is mentioned Averdahl​ described above in 2 ways. First, I used Premiere to split my background motion menu video into two halves - first half is the 8 seconds before the buttons appear and the second half is the remainder of the video which loops forever.

     1. First I set the 8 second video as a timeline that is set to First Play with the End Action pointing to the motion menu comprised of the 2nd half of my video. This still produced a glitch at the point where the first video transitions to the motion menu (main menu).

     2. Next I tried making the 8 second clip a motion menu set to First Play and Loop set to None and the End Action points to the Main Menu with the motion menu background that loops forever, which I believe is what Averdahl suggested above. Again, this produced a glitch at the point where the 2 menus transition - by "glitch" I mean that it shows about a half second of black screen and the audio stops and then begins playing the motion menu again.

It seems to me that this created an even larger glitch than when I had a the Loop Point set originally. Am I still missing something?

Thanks for all the help!

I never use timelines for motion menues, i do always use menues and place the video there. I do however never use audio on my menues so maybe that´s the issue. (?)

Here is a test short Blu-ray test i did. I can see this and navigate to/from menues with no glithes on my OPPO Blu-ray player and on my desktop computer using PowerDVD 17. Download this, unpack the ISO file and try: Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

Does this glitch as well?

I played your BD iso with PowerDVD and it worked just fine. Smooth, seamless transition from the fade to when the buttons started. Is there anything I am missing?

I started a new project, added my intro video and my main menu video as assets. I created 2 new menus for the intro video and the main menu video. I set the intro video as the motion menu for the intro menu, set loop to None and the End Action to the main menu. I set the main video as the motion menu background for the main menu and set it to loop forever with 0 loop point.

After I build the project to an iso and mount it and then play it poerDVD, the glitch is still there. Is there an extra step that you are doing to make the 2 menus flow seamlessly?

Thanks again!

Unfortunately, I am still finding a flicker in the menu after trying (Averdahl)'s method.

Is there any other way, or should I consider a different approach?

Is there any other way, or should I consider a different approach?

If a menu is one minute long and it comes to it´s end there will never be a seamless jump back to the start of the menu. I see this in mass produced Blu-rays as well. Workaround it by doing the menu longer. How long are your menu today?

How are you viewing the result, on a tv set from a burned Blu-ray disc of are you using software on a computer?

It would be great if you can film it so one can see how it actually looks and when it happens and how it looks. If the menu is interlaced it will always look bad while if the menu is progressive it will look good.

I use motion menues in every Blu-ray project i do and stopped using the Loop Point feature for some years ago. I use the fade up video in a Menu as First Play and set the Loop to None and then set End Action of the intro to the main menu. By doing this i don´t have to use the Loop Point feature.

By doing this the glitch caused by the Loop Pint feature is gone.

Intro in a separate file+menues in a separate file/s is the way to go if seameless menues is your goal.

EDIT:

If using the Loop Point: Be aware of that a Loop Point always must point at an I-frame. So if your transition ends at 00:00:05:00 the Loop Point can´t be set to 00:00:05:00, it will find the nearest I-frame which is either 00:00:04:24 or 00:00:05:03. I have a gut feeling that your Loop Point points to a point where the transition has not finished, thus the issue. No matter what, using the Loop Point feature will never create seamless menues.

    Thanks for posting this. I remembered you had an alternative method, but could not find a thread that described it.

      First, if you have not, test with a disk in a player. The actual amount of pause may vary depending on player.

      But, you are probably experiencing a problem in Encore that was not solved before it became end of life.

      Jon Gedes thought he found a workaround using BDEdit, but concluded in the end that he had not.

      Re: Animated menu loop point bug. Any magical fixes found?

      You can try to avoid the loop point by using the pre-loop portion as an intro ending with the menu.

      Thanks for your response.

      I am currently creating both blurays and dvd's of the same content and using the same technique for both,

      however I have not had this problem with dvd's at all.

      Yep. The belief is that it was produced by the method Adobe picked to handle this technique in blurays.
