Show HN: Video editor app that generates FFmpeg commands
Hello Friends, I have built a new video editor app that generates
ffmpeg commands to get the edited video. This gives you flexibility
to use it in scripts etc. for your video editing workflows and
makes editing tasks smooth by letting you visually adjust video
elements that are difficult to adjust in commandline. Demo is here
- https://www.youtube.com/watch?v=KSvazNBEfTc Link is here -
https://newbeelearn.com/tools/videoeditor/ Features are - video,
image, text editing - adjustable timeline and layers - adjust
position, size , alignment, font size color, borders etc. - quick
info of image, video files - preview player to get the idea of
edited video with play, pause, seek. Limitations are - Audio
files(mp3) are currently not supported though audio inside mp4 will
work - player is not frame accurate it just gives u close enough
approximation. - file paths are not supported due to browser's
security limitations. - I have only tested happy path so there
would be many bugs but it should work for simple tasks Others -
Completely free - No registration/login etc. - Works online does
not requires any installation - Works offline after first load -
Works locally does not requires server Background is i generally
have one off video tasks and i don't mind using ffmpeg for it but
recently i had to create a bunch of product videos and it was
difficult to get text etc. right on commandline, i tried kdenlive
and openshot as well but couldn't figure out how to something
simple like adding a logo and text to it(i guess i am dumb) so i
created this new app to suit my workflow

| While only tangentially related, I dove into a rabbit hole not
| long ago trying to find the best ffmpeg GUI (that doesn't require
| Wine or a VM to run on macOS) and found some good stuff.
| Handbrake [1] is great and uses ffmpeg as part of its backend,
| but it gets somewhat limited when you start requiring more
| advanced things like vf chains, scripting/automation,
| obscure/legacy codec support, or specific hardware acceleration
| needs. I wanted to find something that gets (close to) as densely
| packed with features as ffmpeg from the command line, and here's
| what I found. I'm not going to list all their features and
| pros/cons, but just let others know about some of these as a
| starting point.
|
| I'm not affiliated with any of these programs (Handbrake and
| ffmpeg included) in any way, I just want to point others in the
| right direction if they come across this comment.
|
| StaxRip [2] - One of the most popular and complete options. Seems
| like one of the the go-tos on the VideoHelp [3] forums for video
| editing GUIs. Supports AviSynth+ and VapourSynth scripts among
| other advanced features.
|
| clever FFmpeg-GUI [4] - Another VideoHelp go-to. I'm not 100%
| sure if this supports AviSynth/VapourSynth, but it's pretty damn
| feature-complete as far as ffmpeg goes.
|
| Shutter Encoder [5] - Probably has the most intuitive UI of the
| bunch, it feels much closer to a Premiere Pro/Davinci Resolve
| type program rather than an ffmpeg wrapper, albeit those
| applications are much more robust for different tasks.
|
| Hybrid [6] - My favorite out of these, purely because it was easy
| enough to get running on macOS and didn't sacrifice many ffmpeg
| features. Also supports AviSynth/VapourSynth.
|
| Honestly, probably didn't even need to comment this; I wish I had
| more knowledge about these to share in-depth. If you're serious
| about video encoding, your best bet is to start learning how to
| use ffmpeg from the command line anyways, then maybe add
| AviSynth+/VapourSynth into the mix as you see fit, though those
| are a good deal more advanced than even ffmpeg. Just my two
| cents.

| Can you recommend a tool for dicing up 2h digitizations of VHS

| drewp wrote:
| Yeah, I play a VHS tape and capture the whole thing. Maybe

| not for TV shows).
| pdyc wrote:
| u can do it with this command, it will just copy audio and
| video
|
| ffmpeg -i input.mp4 -ss 00:00:00 -to 0:30:00 -c:v copy -c:a
| copy chapter1.mkv
|
| u can just copy paste it 10 times in your text editor, than
| adjust ss, to times using any video player that can play vhs
| file.
| drewp wrote:
| That's where I am now. I'd like to optimize out the
| retyping and duplication of time strings.
|
| I want the player ui (I'm using mpv) to have a command
| that:
|
| 1. Remembers the last end time to use as this chapter's
| start time
|
| 2. Gets the current time to use as chapter-end.
|
| 3. Accepts the name (e.g. 'chapter1').
|
| 4. Runs the ffmpeg copy command.
|
| Perhaps mpv+lua can already handle this. I see commands for
| setting a loop range and for calling a subprocess. Not sure
| how I'd input the chapter name. Maybe I'll have an LLM name
| the chapters for me :)
| pdyc wrote:
| u r on right track with llm, just tell it that you will
| give input file and set of start, end times and that it
| should generate the command for u. As a bonus ask it to
| give u the example as well so that it doesn't
| misunderstands! i think even chatgpt mini should be able
| to do it.
| drewp wrote:
| I found some existing mpv scripts:
|
| https://github.com/oltodosel/mpv-
| scripts/blob/master/show_ch... display chapter names as
| OSD
|
| https://gitlab.com/lvml/mpv-plugin-excerpt press 'i' and
| 'o' for in/out points, then 'x' to make a new (auto-
| named) file.
|
| https://github.com/shinchiro/mpv-createchapter press
| 'shift-c' to mark chapters; export as xml file.
|
| https://github.com/mar04/chapters_for_mpv mark chapter
| times, input titles, save as txt file
|
| By having an LLM name the chapters, I meant having
| whisper do speechrec on the chapter and then asking an LM
| to summarize the content into a name up to k chars.

| Wow!! This is like the pgadmin4 of postgres!!!

| It is much much needed to make ffmepg on par with a video editor!

| I wonder what a gstreamer equivalent would be like.
