AEScripts AfterCodecs v1.12.2 for After Effects Full Version Free Download

AEScripts AfterCodecs v1.12.2 is a professional export and encoding plugin from Autokroma that adds a much broader selection of codecs and encoding controls directly to Adobe After Effects. Its biggest advantage is that it lets you export formats such as Apple ProRes, H.264, H.265 and HAP directly from the After Effects Render Queue, without depending on QuickTime or sending the render through Adobe Media Encoder.

For anyone doing serious motion graphics, VFX, compositing, or delivery work, AfterCodecs is one of those utilities that can become a permanent part of the workflow.

What is AfterCodecs?

AfterCodecs is essentially an alternative professional encoding layer for Adobe’s video applications.

It integrates with:

Adobe After Effects
Adobe Premiere Pro
Adobe Media Encoder

and provides native exporters for:

ProRes
H.264
H.265
HAP

It supports both .MOV and .MP4 workflows and is available on Windows and macOS.

The big deal historically was ProRes encoding on Windows without QuickTime. It also provides additional control over H.264/H.265 encoding that isn’t available through the normal After Effects workflow.

Apple ProRes on Windows

One of AfterCodecs’ most useful features is ProRes export on Windows.

It supports:

ProRes 422 Proxy
ProRes 422 LT
ProRes 422
ProRes 422 HQ
ProRes 4444
ProRes 4444 XQ

It also provides two unofficial profiles:

ProRes 422 Ultra
ProRes 4444 Light

The 4444 Light profile is particularly interesting because it is designed to retain alpha-channel support while reducing file size compared with conventional ProRes 4444.

That is useful for motion-graphics workflows where you need transparent renders for:

Compositing
Broadcast graphics
VFX elements
Lower-thirds
Motion templates
Overlay animations

H.264 and H.265 Encoding

AfterCodecs isn’t just about ProRes.

Its H.264/H.265 encoders provide control over the tradeoff between:

Encoding speed ↔ Quality ↔ File size

You can choose faster encoding for previews or more intensive encoding for final delivery. The developers also claim support for high-resolution encoding up to 8K.

This makes it useful when you need to create:

Client previews
Social-media exports
YouTube videos
Web delivery files
High-quality compressed masters
Small review files

Direct H.264 Export from After Effects

This is one of the practical reasons to install AfterCodecs.

Instead of:

After Effects → Render → Adobe Media Encoder → H.264

you can use:

After Effects → Render Queue → AfterCodecs H.264

The plugin specifically provides H.264/H.265 export directly through the After Effects Render Queue.

That can simplify the workflow considerably.

Advanced H.264/H.265 Controls

AfterCodecs exposes considerably more encoding options than a basic “quality slider”.

Features include:

File-size targeting
10-bit-per-channel encoding
Full-range encoding
YUV 4:2:2
YUV 4:4:4
Tuning profiles
Quality/speed controls

This makes it useful for professional delivery where you actually care about the encoding characteristics rather than simply choosing “H.264”.

File-Size Targeting

The FileSize targeting feature is particularly useful.

Instead of guessing the bitrate needed to hit a particular file size, you can target a desired output size and let the encoder adjust its parameters accordingly.

This can be useful when a client, platform, or upload system imposes a maximum file size.

For example:

5 GB master → target 500 MB delivery file

rather than repeatedly exporting and checking whether the result is small enough.

HAP Codec Support

AfterCodecs also supports all four major HAP codecs from Vidvox.

These are particularly relevant to real-time playback and media-server workflows.

HAP is commonly used for applications involving:

Live visuals
Projection mapping
VJ systems
Large video installations
Real-time playback
Event visuals

AfterCodecs provides the HAP codecs without the resolution restrictions associated with some older workflows.

MultiRender

AfterCodecs also includes MultiRender functionality.

This is particularly useful in Premiere Pro and Media Encoder, where you can batch-export multiple sections of a timeline based on markers.

For example:

Timeline

→ Marker 01 → Product A
→ Marker 02 → Product B
→ Marker 03 → Product C
→ Marker 04 → Product D

MultiRender can turn those sections into separate output files.

That can save a ridiculous amount of repetitive exporting in large projects.

Premiere Pro Features

AfterCodecs isn’t limited to After Effects.

Its Premiere Pro/Media Encoder workflow includes several additional tools, including:

MultiRender Markers
Exporting all audio tracks separately
Quick sub-resolution buttons
Custom frame rates

The Quick Sub Resolutions controls are useful for rapidly switching output dimensions to:

Full
Half
Quarter
Eighth

resolution for preview and delivery workflows.

Custom Frame Rates

AfterCodecs allows custom frame-rate configuration rather than forcing you into a limited set of presets.

That’s useful for specialized workflows involving:

23.976 fps
24 fps
25 fps
29.97 fps
30 fps
50 fps
59.94 fps
60 fps
High-frame-rate output

and other custom delivery requirements.

10-bit and 4:4:4 Workflows

For professional post-production, one of the more interesting aspects is the support for 10 bpc and YUV 4:2:2 / 4:4:4 encoding options.

These options can be important when you’re trying to preserve more colour information through an intermediate or delivery pipeline.

This is much more relevant for:

VFX
Color grading
Broadcast
Professional mastering
High-quality intermediates

than ordinary social-media exports.

YouTube Export Profile

AfterCodecs includes a dedicated YouTube Upload profile.

The goal is to provide a quick export configuration that follows YouTube’s recommended upload characteristics.

So instead of manually configuring:

Codec
Bitrate
Profile
Keyframe settings
Quality

you can use a dedicated preset.

No QuickTime Required

One of AfterCodecs’ historical advantages is that it removes the need for QuickTime-based codec support.

The plugin provides modern codec support directly on Windows and macOS.

That’s particularly important for older After Effects workflows where certain codecs were previously tied to QuickTime components.

Batch Rendering

If you’re dealing with hundreds or thousands of deliverables, AfterCodecs becomes considerably more useful.

The developer specifically highlights the ability to batch export thousands of videos through MultiRender.

This is useful for:

Localization
Social media campaigns
Automated advertising
Product variants
Multiple aspect ratios
Client versions
Data-driven video

After Effects Render Queue Integration

AfterCodecs integrates directly into the After Effects Render Queue.

That means you don’t have to abandon the familiar AE workflow.

A typical workflow becomes:

Composition

↓

Add to Render Queue

↓

Output Module

↓

AfterCodecs

↓

Codec + parameters

↓

Render

This is one of the reasons it feels much more natural than a standalone encoder.

Performance

AfterCodecs is designed around fast native encoding and regularly receives codec and performance updates. The developer specifically markets H.264/H.265 as providing a range from fast preview encoding to higher-quality final encoding.

Actual encoding speed depends heavily on:

CPU
GPU
Resolution
Codec
Bitrate
Encoding profile
Source complexity

So don’t interpret “fast” as a fixed performance number.

Compatibility

The current AfterCodecs listing supports:

After Effects: 2017 through 2026
Premiere Pro: 2017 through 2026
Media Encoder: 2017 through 2026

It supports Windows 10/11 and macOS versions from macOS 12 Monterey through macOS 26 Tahoe, including Apple Silicon and Intel Macs.

The official changelog shows that v1.12.1, released January 24, 2026, added support for Adobe’s 2026 applications.

One thing to note: the official page currently exposes version-history information through 1.12.1, so I would treat your stated v1.12.2 as the specific build you’re cataloguing rather than claiming additional 1.12.2 features that aren’t documented on the official page.

AfterCodecs vs Adobe Media Encoder

This is where AfterCodecs makes the most sense.

Feature	AfterCodecs	Adobe Media Encoder
Direct AE Render Queue encoding	✅	Usually separate workflow
ProRes on Windows	✅	Supported
H.264	✅	✅
H.265	✅	✅
HAP	✅	❌
MultiRender	✅	Limited/different workflow
File-size targeting	✅	Limited
10-bit options	✅	Depends on codec
4:2:2 / 4:4:4 options	✅	Codec-dependent
YouTube preset	✅	✅
QuickTime dependency	❌	❌

The important point isn’t that AfterCodecs makes Media Encoder obsolete. Adobe Media Encoder is still a much broader encoding application.

AfterCodecs is valuable because it gives you more direct control from the Adobe timeline and adds codecs/features that Adobe’s standard exporter doesn’t provide in the same way.

Who Should Use AfterCodecs?

After Effects Artists

Probably the most obvious audience.

If you regularly export ProRes, H.264 or H.265, being able to do it directly from the AE Render Queue is extremely convenient.

VFX Artists

The ProRes 4444 workflows are particularly useful for transparent VFX elements and intermediate renders.

Motion Designers

Useful for quickly generating:

Client previews
Social exports
ProRes masters
Alpha-channel overlays
Review files

Broadcast Designers

ProRes, high-quality intermediates, custom encoding and alpha workflows make AfterCodecs particularly relevant.

Video Production Studios

MultiRender becomes valuable when generating large numbers of deliverables.

Where It Fits in Your Pipeline

For the software collection you’ve been building, AfterCodecs belongs at the very end of the pipeline.

For example:

Blender / Houdini / Cinema 4D / 3ds Max

↓
Rendering

↓

After Effects

↓
Compositing + Motion Graphics

↓

AfterCodecs

↓
ProRes / H.264 / H.265 / HAP

That’s a very clean workflow.

And unlike something like another visual-effects plugin, AfterCodecs doesn’t compete with your existing software. It fixes the delivery/export stage.
