This ones a bit meta , if your running low on time to make a presentation video for your FLORA technique, #FLORATechnique. I made one to quickly make an explainer vid by providing it some screenshots and a description of your technique / software. Give it an overview screenshot and 4 supplementary screens. And you get 30 seconds of 5 separate 6 seconds videos with narration you can download and merge or edit. See attached compiled video few sample of what it outputs, the last bit on the compiled video is seedance being seedance 🤪 Try it here: https://app.flora.ai/techniques/explainer

Here's an example process with ffmpeg command to do that last part quickly:

Create an input file list (inputs.txt) listing all video clips names in order , note the file prefix is literal as are the quotes: file 'clip1.mp4' file 'clip2.mp4' file 'clip3.mp4'

Then this ffmpeg command: ffmpeg -f concat -safe 0 -i inputs.txt -i audio.mp3 -c:v copy -c:a aac -map 0:v:0 -map 1:a:0 -shortest output.mp4

Parameters Explanation, -f concat -safe 0 -i inputs.txt: Uses the concat demuxer to read the list of files. -i audio.mp3: Inputs the single audio file. -c:v copy: Stream copies the video (fast, no re-encoding). -c:a aac: Re-encodes audio to AAC for better compatibility with MP4. -map 0:v:0 -map 1:a:0: Takes the video from the first input (concat) and audio from the second input. -shortest: Ends the output file when the shortest input (likely the audio) finishes.
