| I don't find trimming videos with ffmpeg particularly difficult, is just-ss xx -to xx -c copy basically. Sure, you need to get those time stamps using a media player, but you probably already have one so that isn't really an issue. What I've found to be trickier is dividing a video into multiple clips, where one clip can start at the end of another, but not necessarily. |

| ▲ | sorenjan 3 hours ago | parent [-] | | Missed opportunity to reference the famous Dropbox hn comment. I just think there are other closely related use cases where a separate program can add more value, especially in the terminal. I wouldn't suggest most people should use ffmpeg instead of a gui, those are too dissimilar. Another example is cutting out a part of a video, with ffmpeg you need to make two temporary videos and then concatenate them, that process would greatly benefit from a better ux. | | |
| ▲ | tptacek 2 hours ago | parent | next [-] | | Point of order: the Dropbox HN comment is famously misconstrued. People think it was about Dropbox; it was about the Dropbox YC application, and was both well-intentioned and constructive. | |

| ▲ | hiccuphippo 2 hours ago | parent | prev [-] | | I used a plugin in mpv to do it but I can't find it anymore. You just pressed a key to mark the start and end. And with . and , you could do it at keyframe resolution not just seconds. |

| I asked about this tool 3 days ago, HN is a magical place! https://news.ycombinator.com/item?id=47363432 |

| This is very cool. I built one of these myself around Christmas; Claude Code can put one together in just a couple prompts (this is also how I worked out how to have Claude test TUIs with tmux). What was striking about my finished product --- which is much less slick than this --- was how much of the heavy lifting was just working out which arguments to pass to ffmpeg. It's surprisingly handy to have something like this hanging around; I just use mine to fix up screen caps. Commenting mostly because when I did this I thought I was doing something very silly, and I'm glad I'm not completely crazy. |

| ▲ | booi 28 minutes ago | parent [-] | | You can use AI to figure out the arguments to ffmpeg. But indeed it seems like there's just a single call to FFmpeg CLI to power the whole thing which is amazing. ffmpegCmd := exec.Command("ffmpeg",
"-ss", fmt.Sprintf("%.3f", position.Seconds()),
"-i", p.path,
"-vf", strings.Join(filters, ","),
"-vframes", "1",
"-f", "image2pipe",
"-vcodec", "bmp",
"-loglevel", "error",
"-",
)

| Invoking ffmpeg, gzip and tar commands is a sort of reverse Turing test for LLMs |

| I think this is the first instance I've seen of an actual terminal video player. Very fun to play with. |
| |
| ▲ | mikkupikku 4 hours ago | parent [-] | | mplayer, mpv and I think VLC can do it, with the right output driver settings (libcaca or a few other choices.) | | |
| ▲ | tptacek 4 hours ago | parent | next [-] | | You can just use ffmpeg to extract frames, and then just render the raw images with unicode blocks. (There's Kitty Graphics too, but I couldn't figure out how to make terminal UI layout work with it.) | |
| ▲ | chadrs 4 hours ago | parent | prev [-] | | yeah I remember learning this trick in like 2007 with libaa and later caca for color. It looks like this app is shelling out to ffmpeg to get the bitmap of a frame and then shelling to something called chafa to covert to nice terminal-friendly video. https://github.com/hpjansson/chafa/ |

| I have been using this one[0] and it is small, fast, and seems to work pretty great for me so far. [0]https://github.com/wong-justin/vic |

| ▲ | wonger_ 8 minutes ago | parent [-] | | Happy to hear! Some of my thoughts when building it: - I haven't implemented audio support yet, but it would be nice - I like --dry-run - I didn't use a TUI widget library, but now it's at the point where it's tedious to refactor the UI / make it prettier - I like OP's timeline widget - Wanted to focus on static binaries. I got chafa static linking working for Linux, but haven't bundled ffmpeg yet - which reminds me of licenses -- chafa and ffmpeg are LGPL iirc - a couple other notes from early on: https://wonger.dev/posts/chafa-ffmpeg-progress |

| On MacOs I just press space and trim with finder. Even avoids re-compressing. |

| Could have really used this a couple days ago. I had to record a video an assignment, but due to lack of global hotkeys on OBS with wayland, I had to start and stop the video on the OBS GUI. I tried to figure out ffmpeg but I was too tired and it was getting close to the deadline so I spent some time learning how to to do it with kdenlive. |

| Having to separately download ffmpeg in the windows distribution does not really make sense Just bundle it |
| |
| ▲ | sorenjan 3 hours ago | parent | next [-] | | I disagree, I don't want another ffmpeg binary, I already have one. Winget works well, especially since this is already a terminal program. | |
| ▲ | ftchd 2 hours ago | parent | prev | next [-] | | People that use GUIs/tools for things like ffmpeg, rclone etc really want the developer to autodetect if they have it already, and use that instead of installing a separate version/binary. How do I know? I built one (https://github.com/rclone-ui/rclone-ui) | |
| ▲ | karlosvomacka 3 hours ago | parent | prev [-] | | afaik winget can automatically manage package dependencies. |

| I've been using ffmpeg with claude as video editor for long time. |
| |
| ▲ | hsuduebc2 3 hours ago | parent [-] | | You mean you let create claude command or it itself runs ffmpeg on your local machine and returns you finished cut? |

| I guess I can find another implementation to combine trimmed parts after taking out certain scenes? |
| |
| ▲ | hiccuphippo 4 hours ago | parent [-] | | Write a text file with all the parts like this: file 'file1.mp4'
file 'file2.mp4'
file 'file3.mp4'
Then call ffmpeg like this: ffmpeg -f concat -i files.txt -c copy output.mp4
And I guess you could make an LLM write a {G,T}UI for this if you really want. |
