## Speed up video
If you need speed up your final video file, install `ffmpeg`` and run one of these commands for the desired speed:
**Speed 1.2:**
```
ffmpeg -i temp/movie-out.mp4 -filter_complex "[0:v]setpts=0.8333*PTS[v];[0:a]atempo=1.2[a]" -map "[v]" -map "[a]" -c:a mp3 temp/movie_1_2x_with_audio.mp4
```
**Speed 1.5:**
```
ffmpeg -i temp/movie-out.mp4 -filter_complex "[0:v]setpts=0.6667*PTS[v];[0:a]atempo=1.5[a]" -map "[v]" -map "[a]" -c:a mp3 temp/movie_1_5x_with_audio.mp4
```
**Speed 1.75:**
```
ffmpeg -i temp/movie-out.mp4 -filter_complex "[0:v]setpts=0.5714*PTS[v];[0:a]atempo=1.75[a]" -map "[v]" -map "[a]" -c:a mp3 temp/movie_1_75x_with_audio.mp4
```
**Speed 2.0:**
```
ffmpeg -i temp/movie-out.mp4 -filter_complex "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]" -map "[v]" -map "[a]" -c:a mp3 temp/movie_2x_with_audio.mp4
