| | |
| | Thermalvideo exportieren: |
| | <code> |
| | ffmpeg -i "YUN_0210.mp4" -y -vcodec libx264 -movflags faststart -map 0:v:1 -pix_fmt yuv420p "YUN_0210-thermal.mp4" |
| | </code> |
| | |
| | Normalvideo exportieren: |
| | <code> |
| | ffmpeg -i "YUN_0210.mp4" -y -vcodec libx264 -movflags faststart -map 0:v:0 -pix_fmt yuv420p "YUN_0210-normal.mp4" |
