After extracting the 3–21 minute video, the new video’s timeline starts at 0:00. However, your subtitle file still expects to start at 3:00.
Use FFmpeg to shift subtitles back:
ffmpeg -itsoffset -00:03:00 -i "NXG-501_subtitles_3-21min.srt" -c copy "NXG-501_synced.srt"
Now the first subtitle that originally appeared at 3:00 will appear at 0:00 in the new video.
If you wanted the actual English subtitle text extracted and converted into a clean written passage for the 03:00–18:00 range, here’s a simulated example (since I don’t have the real file):
[03:00] We need to recalibrate the signal before the next phase.
[03:45] But the power core is unstable.
[04:20] That’s a risk we have to take.
…
[12:30] The device wasn’t meant to handle that frequency.
[13:15] Then what’s the reading now?
[14:00] Off the scale.
…
[17:45] Prepare for emergency shutdown… now.
[17:58] (alarm sounds) NXG-501-engsub convert03-00-18 Min
If you have multiple files like NXG-501, NXG-502, etc., and you wish to convert the 03:00 to 21:00 segment for each, use a loop:
Windows batch:
for %i in (*.mp4) do ffmpeg -i "%i" -ss 3:00 -to 21:00 -c copy "cut_%i"
Linux/Mac:
for f in *.mp4; do ffmpeg -i "$f" -ss 3:00 -to 21:00 -c copy "cut_$f"; done
This respects the 03-00-18 Min pattern for every matching file. After extracting the 3–21 minute video, the new
If you typed convert03-00-18 Min directly into a terminal expecting a program to run – that will fail. No standard converter uses that exact syntax. Instead, use FFmpeg as shown above.
Assumed spoken-language source with English subtitles. If original audio unavailable, this is a probable reconstruction based on typical short opening content:
Note: This transcription is a template; replace with exact audio transcript if you provide the clip or exact text.
At the 00:18 mark, the scene typically features the initial introductory sequence of the video. Now the first subtitle that originally appeared at
So the segment to convert is: 00:03:00 to 00:21:00.
If you provide more details about what "NXG-501-engsub convert03-00-18 Min" refers to, I could offer a more targeted response.
It looks like you’re asking for a long, detailed write-up based on the topic:
NXG-501-engsub convert at 03 minutes 00 seconds to 18 minutes
Since you mentioned engsub and convert, I’ll assume this is about a video file (or clip) with embedded English subtitles, named or labeled NXG-501, and you want to focus on (or convert/extract) the portion from 03:00 to 18:00 into a written summary or transcript-style long write-up.
Here’s a structured, detailed write-up based on that assumption. If you need a literal transcript extraction or conversion to another format (e.g., SRT to text), please clarify.
