1. In Subler, it seems I can edit Chapter Names without having to encode the file all over again, but have to with iFlicks 2. Why are the two different? 2. Does editing metadata such the poster, cast, date, etc, effect the actual file of the movie? My plan is to store all my movies on a hard drive and be able to update the just metadata as it changes on TMDB for example lets say every year so it is all current. So will overtime all these revisions of the metadata effect the file? 3. Is there a way to protect a file from deletion? For example I could set a password for a file and to be able to delete it or edit it I would have to unlock it first. 4. Anyone know what AC3 is? From what my understanding, is it is the uncompressed audio bitrate from the movie and can be played if the stereo audio isn't supported? 5. In iFlicks 2, what does the option Update Metadata and Rename mean, and how does it differ from the option Update Metadata? 6. Does MakeMKV also save the Chapter names? It saves the correct time stamps but I can't find the names... I will reply more questions I have, because they are bound to come.
