Troubleshooting of runway issues

== Resolve the error 'Generation error' ==
=== Error condition ===
After waiting patiently for several minutes in the queue for a video generation task to be processed, I encountered a "Generation error" which prevented the video from being successfully produced. The complete error message is as follows:

<pre>
Generation error

Your credits will be refunded. Please try again or adjust your prompt if you continue to encounter this error.
</pre>

The official Runway FAQ addresses the "Generation error" issue in their article "[https://help.runwayml.com/hc/en-us/articles/32880432736659-Why-am-I-getting-an-error-when-I-m-trying-to-generate Why am I getting an error when I'm trying to generate? – Runway]" The explanation provided is that "The model is unable to produce a high-quality output based on your inputs, and to avoid wasting your credits, the generation process was terminated."

=== Solution ===
# Refine your prompt: Modify how you describe the desired shot or scene.
# Adjust your reference image: Either make changes to your current reference image or try using a different one altogether.

== Fixing Time Sequence Errors in Generated Videos ==
=== Error condition ===
"Sometimes the generated video is good, but the time sequence is incorrect. For example, you might want to show a customer entering a café, but the generated video shows the customer leaving the café instead.

=== Solution ===
Use ffmpeg to reverse the playback order of the video.

# Go to [https://www.ffmpeg.org/download.html Download FFmpeg] website to download & install ffmpeg software.
# Open the terminal
# To reverse audio and video. Key in the command<ref>[https://github.com/sakydev/til/blob/main/ffmpeg/reverse-a-video-in-ffmpeg.md til/ffmpeg/reverse-a-video-in-ffmpeg.md at main · sakydev/til]</ref> {{kbd | key=<nowiki>ffmpeg -i input.mp4 -vf reverse -af areverse output.mp4</nowiki>}}

Explanation of options (from {{kbd | key=<nowiki>ffmpeg --help</nowiki>}})
* -i <input file>
* -vf <filter_graph> alias for -filter:v (apply filters to video streams)
* -af <filter_graph> alias for -filter:a (apply filters to audio streams)

== Fixing Artifacts in AI-Generated Videos ==
=== Error condition ===
Sometimes the beginning of generated videos may have strange shaking, dark shadows, or other unusual phenomena.

=== Solution ===
Change the duration of the video generated in Runway from 5 seconds to 10 seconds, then use ffmpeg to trim the video and remove the unsuitable parts.

# Go to [https://www.ffmpeg.org/download.html Download FFmpeg] website to download & install ffmpeg software.
# Open the terminal
# To remove the first 3 seconds of the video. Key in the command<ref>[https://stackoverflow.com/questions/18444194/cutting-multimedia-files-based-on-start-and-end-time-using-ffmpeg Cutting multimedia files based on start and end time using ffmpeg - Stack Overflow]</ref> {{kbd | key=<nowiki>ffmpeg -i input.mp4 -ss 00:00:03 -c copy output.mp4</nowiki>}}

Explanation of options (from {{kbd | key=<nowiki>ffmpeg --help</nowiki>}})
* -i <input file>
* -ss <time_off> start transcoding at specified time
* -c[:<stream_spec>] <codec> select encoder/decoder ('copy' to copy stream without reencoding)
