Advanced encoding notes for The Batman (2022)
These notes are primarily used for precision audio sync, XML shift-script recommendations for different sources of the film/series, and notes on any peculiarities with the source material. Please note that these are situational, for example the precision audio sync details are meant for advanced/perfectionist users and not required to encode a decent quality edit.
If you're encoding an edit for the first time it's best to just use the default mp4 export from your NLE program and not mess with trying to get absolutely perfect quality until you're comfortable with the basics of loading, calibrating, and exporting an edit video. However, some Advanced pages list "Shift script values" that may make life easier for beginners trying to calibrate their BluRays.
The sync on these films is a bit strange because Batman Begins is FAR off from synced with an 83ms delay relative to video shown by Mediainfo's advanced mode. The video on Batman Begins is also misaligned 12 pixels vertically.
Batman Begins: BluRay MLP Audio, add 3712 sample delay (yes, a whole 77.33ms!)
The Batman: BluRay AC3 Audio, delay 8ms from perfect mkv audio sync
Dark Knight Rises: BluRay DTS-MA Audio, hasten 7ms from perfect mkv audio sync
Shift script values for BluRay encoding:
-----
# the batman bluray
$fta_ht = @{
"459" = -216;
"460" = -2;
"458" = 0;
}
