# mpv-cut
## What Is This
This extension allows you to:
The core functionality of this script is to very
quickly cut videos both losslessly and re-encoded-ly
with the help of the fantastic media player
[mpv](https://mpv.io/installation/).
- Quickly cut videos both losslessly and re-encoded-ly.
There is also the added functionality of:
- Logging the timestamps of cuts to a text file for later use with the `make_cuts` script.
- Logging the current timestamp to a bookmark file and reloading them as chapters in mpv.
- Specify custom actions in a `config.lua` file to support your own use cases
without having to modify the script itself or write your own extension.
More details in [usage](#usage).
- Bookmark timestamps to a `.book` file and load them as chapters.
- Save cut information to a `.list` file for backup and make cuts later.
- Choose meaningful channel names to organize the aforementioned actions.
All directly in the fantastic media player [mpv](https://mpv.io/installation/).
## Requirements
Besides mpv, you must have the following in your PATH:
- ffmpeg
- node
Besides mpv, you must have `ffmpeg` in your PATH.
## Installation
#### Linux/MacOS
```
git clone -b release --single-branch "https://github.com/familyfriendlymikey/mpv-cut.git" ~/.config/mpv/scripts/mpv-cut
```
#### Windows
In
`%AppData%\Roaming\mpv\scripts` or `Users\user\scoop\persist\mpv\scripts` run:
```
git clone -b release --single-branch "https://github.com/familyfriendlymikey/mpv-cut.git"
```

### Cutting A Video Losslessly
- Press `c` to begin a cut.
- Seek to a later time in the video.
- Press `c` again to make the cut.
The resulting cut will be placed in the same directory as the source file.
### Other Actions
### Actions
You can press `a` to cycle between the two default actions:
You can press `a` to cycle between three default actions:
- Copy (lossless cut, rounds to keyframes).
- Encode (re-encoded cut, exact).
### Cutting To Global Dir
- List (simply add the timestamps for the cut to a `.list` file).
You can press `g` to toggle saving to the
configured global directory as opposed to
the same directory as the source file.
### Cut Lists
Instead of making cuts immediately, you can choose to store all cuts
in a "cut list" text file.
Toggle this behavior with the `l` key.
When you're ready to make your cuts, press `0` in mpv.
The `make_cuts` script can also be invoked directly.
The very last argument must be rows of JSON.
In the case of a cut list, you can simply do
```
./make_cuts "$(cat cut_list_name.list)"
```
Preceding the aforementioned JSON argument may be 0 to 2 arguments:
- If there are `0` arguments,
it will use the current working directory
as the input dir to look for the filenames of the cuts passed
to it, and will also output cuts to the current directory.
- If there is `1` argument, it will use it
as both the indir and outdir.
- If there are `2` arguments, it will use the first one
as the indir and the second one as the outdir.
If any of the filenames do not exist in the indir,
the ffmpeg command for that cut will simply fail.
`mpv-cut` uses an extensible list of *actions* that you can modify in your
`config.lua`. This makes it easy to change the `ffmpeg` command (or any command
for that matter) to suit your specific situation. It should be possible to
create custom actions with limited coding knowledge. More details in
[config](#config).
### Bookmarking
Press `i` to append the current timestamp to a bookmark text file.
This automatically reloads the timestamps as chapters in mpv.
You can navigate between these chapters with the default mpv bindings,
`!` and `@`.

### Channels
The resulting cuts and bookmark files will be prefixed a channel
number. This is to help you categorize cuts and bookmarks. You
can press `-` to decrement the channel and `=` to increment the
channel.

## FAQ
### Why Do I Need Node?
The actual `mpv-cut` extension acts as a sort of minimal interface to an
arbitrary `make_cuts` binary. This way, users can extend the
functionality using whatever language they want, without being tied to
LUA and relying on `mpv`'s API. Most people on GitHub know how to code
in some language, but not everyone wants to learn LUA and an API to
cut their videos.
I chose to write the default `make_cuts` script in Imba, an extremely
underrated language that compiles to readable JavaScript. Python would
have been a good candidate as well, but Python's VM takes
significantly longer to start up than Node's which I didn't like.
### What Is The Point Of A Cut List?
There are plenty of reasons, but to give some examples:
- Video seems to be pretty complex, at least to me.
One video file may cause certain issues,
and another may not, which makes writing
an ffmpeg command that accounts for all scenarios difficult.
If you spend a ton of time making many cuts in a long movie
only to find that the colors look off because of some
10-bit h265 dolby mega surround whatever the fuck,
with a cut list it's trivial to edit
the ffmpeg command and re-make the cuts.

- Maybe you forget that the foreign language video you're cutting has
softsubs rather than hardsubs,
and you make a bunch of encode cuts
resulting in cuts that have no subtitles.

- You delete the source video for storage reasons,
but still want to have a back up of the cut timestamps
in the event you need to remake the cuts.

### Why Would I Bookmark Instead Of Cutting?
Suppose you're watching a movie or show for your own enjoyment,
but you also want to compile funny moments to post online
or send to your friends.
It would ruin your viewing experience to wait for a funny
moment to be over in order to make a cut.
Instead, you can quickly make a bookmark whenever you laugh,
and once you're done watching you can go back and make actual cuts.

### Why Is Lossless Cutting Called "Copy"?
This refers to ffmpeg's `-copy` flag which copies the input stream
instead of re-encoding it, meaning that the cut will process
extremely quickly and the resulting video will retain
100% of the original quality.
The main drawback is that the cut may have some extra
video at the beginning and end,
and as a result of that there may be some slightly wonky behavior
with video players and editors.

- As mentioned above, copying the input stream is very fast and lossless
but the cuts are not exact. Sometimes you want a cut to be exact.

### How Can I Merge (Concatenate) The Resulting Cuts Into One File?
To concatenate videos with ffmpeg,
you need to create a file with content like this:
To concatenate videos with ffmpeg, you need to create a file with content like
this:
```
file cut_1.mp4
file cut_2.mp4
file cut_3.mp4
file cut_4.mp4
```
You can name the file whatever you want, here I named it `concat.txt`.
Then run the command:
```
ffmpeg -f concat -safe 0 -i concat.txt -c copy out.mp4
```
That's annoying though, so you can skip
manually creating the file by using bash.
This command will concatenate all files in the current directory
that begin with "COPY_":

```
ffmpeg -f concat -safe 0 -i <(printf 'file %q\n' "$PWD"/COPY_*) -c copy lol.mp4
```
- You need to escape apostrophes which is why
we are using `printf %q "$string"`.
- Instead of actually creating a file we just
use process substitution `<(whatever)` to create a temporary file,
which is why we need the `$PWD` in there for the absolute path.

You can also do it in vim, among other things.
```
ls | vim -
:%s/'/\\'/g
:%norm Ifile
:wq concat.txt
```
This substitution might not cover all cases, but whatever,
if you're concatenating a file named `[{}1;']["!.mp4`
you can figure it out yourself.

### Can I Make Seeking And Reverse Playback Faster?
Depending on the encoding of the video file being played, the following may be quite slow:
Depending on the encoding of the video file being played, the following may be
quite slow:
- The use of `exact` in `input.conf`.
- The use of the `.` and `,` keys to go frame by frame.
- The holding down of the `,` key to play the video in reverse.
Long story short, if the video uses an encoding that is difficult for mpv to decode,
exact seeking and backwards playback won't be smooth, which for normal playback is not a problem at all,
since by default mpv very quickly seeks keyframe-wise when you press `left arrow` or `right arrow`.

decode, exact seeking and backwards playback won't be smooth, which for normal
playback is not a problem at all, since by default mpv very quickly seeks
keyframe-wise when you press `left arrow` or `right arrow`.
However if we are very intensively cutting a video,
it may be useful to be able to quickly seek to an exact time, and to quickly play in reverse.
In this case, it is useful to first make a proxy of the original video which is very easy to decode,
generate a cut list with the proxy, and then apply the cut list to the original video.

it is useful to first make a proxy of the original video which is very easy to

original video.
To create a proxy which will be very easy to decode, you can use this ffmpeg command:
```
ffmpeg -noautorotate -i input.mp4 -pix_fmt yuv420p -g 1 -sn -an -vf colormatrix=bt601:bt709,scale=w=1280:h=1280:force_original_aspect_ratio=decrease:force_divisible_by=2 -c:v libx264 -crf 16 -preset superfast -tune fastdecode proxy.mp4
```
The important options here are the `-g 1` and the scale filter.
The other options are more or less irrelevant.
The resulting video file should seek extremely quickly
and play backwards just fine.
Once you are done generating the cut list,
simply open the `cut_list.txt` file,
substitute the proxy file name for the original file name,
and run `make_cuts` on it.

## Development
Uploading releases to GitHub is a pain, so I thought why not create an orphaned branch for releases.
To set it up, all I did was:
```
git checkout --orphan release
```
Then, when I want to release a new version, until I find a better way I just do:
```
TMPDIR=`mktemp -d`
cp dist/* "$TMPDIR"
git checkout release
git rm -r '*'
cp "$TMPDIR"/* .
git add --all
git commit -m "version number"
git push
```
Once you are done generating the cut list, simply open the `cut_list.txt` file,
substitute the proxy file name for the original file name, and run `make_cuts`
on it.
