Het begint.
- Sluit de poorten voor vanavond...

en verdubbel de beveiliging op de muur.

00:00:04,356 --> 00:00:06,593
Wat voorafging in The Walking Dead.

00:00:07,579 --> 00:00:10,251
De mensen schijten
in hun broek van angst.

Synced Subs:

1
00:00:01,004 --> 00:00:02,404

00:00:06,369 --> 00:00:08,385

It seems the original subs are complete wrong. Looks like a different episode. But after the sync its looks alot better. But still few sec out-sync

00:00:01,585 --> 00:00:03,353
Here's to the sale of our flip house.

2
00:00:03,378 --> 00:00:05,878
Much like me, it looks
good on the outside,

3
00:00:05,914 --> 00:00:07,797
but it has a questionable foundation.

Synced:

1
00:00:06,615 --> 00:00:08,383
Here's to the sale of our flip house.

2
00:00:08,408 --> 00:00:10,908
Much like me, it looks
good on the outside,

3
00:00:10,944 --> 00:00:12,827
but it has a questionable foundation.

This one is complete out-sync. The first one must start around: 00:00:02,200 --> 00:00:04,100

Start by reproducing the issue with the subsync commands and subtitle samples shown for both episodes. Compare the generated subtitle timings with the stated expected offsets and investigate why synchronization remains incorrect when the input subtitles appear to belong to another episode. Done means the reported cases produce correctly aligned subtitles or are rejected with a clear explanation.
