608 to scc has truncated lines... maybe?

a@slo.me
I'm running the command

ffmpeg  -f lavfi -i movie="1.mp4[out+subcc]" \
 -map 0:1 -c copy  out1.scc \
 -map 0:1  out1.vtt \
 2> con.txt

The video file is here

> https://slo.me/ffscc/1.mp4

con.txt, out1.scc, and out1.vtt are attached.

my scc file comes out like this



Scenarist_SCC V1.0

00:00:00:03     9420

00:00:00:04     94f4

00:00:00:05     5b6d

00:00:00:06     7573

00:00:00:07     e9e3

00:00:00:08     2070

00:00:00:09     ec61

00:00:00:10     79e9

00:00:00:11     6e67

00:00:00:12     5d80

00:00:00:13     942c

00:00:00:16     942f

00:00:02:04     942c

00:00:04:13     9420

00:00:04:14     9452


however, my webvtt file comes out as expected


WEBVTT

00:00.533 --> 00:02.135
[music playing]

00:05.538 --> 00:08.641
\h\h\h- In Egypt’s capital,
Cairo, one environmentalist

00:08.742 --> 00:13.546
taps into the power of community
to spread his green message.

00:13.646 --> 00:14.981
My name is Sharif Hosny.

00:15.081 --> 00:16.916
I’m the co-founder of Schaduf.

00:17.017 --> 00:21.187
- Schaduf is an Arabic word for
an ancient irrigation tool that

00:21.287 --> 00:24.190
is still used by farmers today.

00:24.290 --> 00:28.228
It lifts water to irrigate
\hcanals to harvest crops.




I'm not sure of my mistake.


Thank you for your time,

Adrian

My apologies, I see it now.

ffmpeg   -i out1.scc -map 0 out2.vtt

and it outputs the same as the out1.vtt .
