macOS

Supported OS: High Sierra, Mojave, Catalina and Big Sur.

Installation

1. Disable Gatekeeper.

Open the Terminal.app (Applications/Utilities)

Type or paste in the following command and press Enter:

sudo spctl --master-disable

Re-enable gatekeeper again with this command:

sudo spctl --master-enable

I do this after running vapoursynth at least one time.

It will ask for your password (because we are using the sudo command).

Enter your macOS password (you won't see the characters!)

2. Download VapourSynth: here
3. Install Miniconda.pkg.

Select "Install for me only"

4. Open the Terminal.app (Applications/Utilities)

Type or paste in the following command and press Enter:

conda install -c conda-forge imagemagick

When asked if you want to proceed, type in "y" and press Enter:

Let it run, it will take some time.

5. Install VapourSynth.pkg

This will install a folder in your desktop with some shortcuts.

6. Install everything else.

Move the video_edit folder to /Library/Frameworks/VapourSynth.framework (Finder -> Go -> Go to the Folder)

Create a shortcut to video_edit and place it in the vapoursynth folder on your desktop. (the alias name has to be "video_edit").

Right Click -> Make Alias

Then copy the alias and paste it here:

Move the ffmpeg folder to /Library/Frameworks/VapourSynth.framework/bin

Move all the plugins to "VapourSynth/Add Plugins" and the scripts to "VapourSynth/Add Scripts"

Move vsedit.config to ~/Library/Preferences

Move the nnedi3 folder to /usr/local/share (if the share folder is missing, go to usr/local and create it)

Add VapourSynth.app to the dock.

Usage

Drag any video onto VapourSynth.app

A window will appear asking you to enter the timestamp you want:

Then it will ask you to enter the time you want to extract (let's say 4 seconds from the timestamp we entered before):

After that, the resizer and vapoursynth editor will open.

First thing you have to do is open script.vpy from the editor.

If you are low in RAM, enable the core.max_cache_size line. This is done by removing the hash # at the beginning of the line.

Now, the resizer is self-explanatory. I won't explain much here (just don't use vcfreq, finesharp is better)

Copy the code and paste it here:

Now what I do first is disable all filters except the essential ones (like debilinear to resize and the crop one)

If I run them all at the same time, my computer suffers a lot xD

If you are running on a potato you can't really do much

Preview your script and select the frames you want to extract for your gif.

I'll extract frames 20 to 45. You'll have to add these numbers in the Trim parameters.

Now, enable all filters again and save the script. If you want to see the output, preview the script, but don't run it in real time.

Important: check the script before encoding (editor -> Script Tab -> Check Script). Errors will show up here. If no errors are found, then you will see this message:

To get the output, we can use makepsd or the encode feature inside vsedit.

Encoding

makepsd

This is the best since we get the output in .psd format.

After saving the script, go to video_edit and double click on "makepsd"

You'll see a gear on top of your screen. Wait for it to finish.

It will save the .psd in /output

vsedit "Encode video"

Editor -> Script Tab -> Encode video

You have two presets (you can add more tho): rawvideo and png sequence.

Make sure the Header is always Y4M.

Click on start to begin.

After finishing encoding, you can import the video in PhotoShop.
