Is it possible to replace the video file in a timeline without losing the Encore chapter marks? I do not mean dynamically linked video from Premiere or AE, but pre-rendered video imported into Encore CS6 and chapter markes created in Encore.
I am having an issue with Encore insisting on transcoding my .264 video file, so I want to replace it with a .m4v file, but I do not want to lose the chapter marks in doing so. It's annoying having to add them over and over again.
I think that the "Replace Asset" function should work for you. Try right clicking on the asset in the project window, and select the new video.
Just make damn sure the new assets has a different name than the original. The change of extension should be enough, but I'd change the file name as well, just to be sure. I typically add a _r for a revised version, with _ra and _rb for each successive revision.
