What's the difference between Free and PRO?

The Free version is limited to 50 files per batch but includes all features: EXIF-based auto organization, filename patterns, preset management, GPS sorting, and more. PRO ($9.99 one-time purchase) removes the file limit for unlimited processing. Try the Free version first!

How long can I use the Free version?

The Free version has no time limit - it's free forever. It's not a trial period, so you can use it permanently for up to 50 files per batch.

Complete Guide to Video & Audio Formats

"What's the difference between MP4 and MOV?" "Should I use H.264 or HEVC?"

Video and audio formats come in many varieties, and the relationship between containers and codecs can be confusing.

This guide explains the fundamentals of video and audio formats, from basic concepts to practical recommendations for every use case.

Containers vs Codecs

The most important concept to understand is the difference between containers and codecs.

Containers (File Formats)

A container is the "box" that holds video and audio data together in a single file.

Container	Extension	Key Feature
MP4	.mp4	Most universal. Plays on virtually all devices
MOV	.mov	Apple-developed. Excellent Final Cut Pro integration
MKV	.mkv	Supports many codecs/subtitles. Highly flexible
WebM	.webm	Google-developed. Optimized for web delivery

Codecs (Compression Algorithms)

A codec is the algorithm that compresses and decompresses video/audio data.

Video Codecs:

Codec	Full Name	Key Feature	Primary Use
H.264	AVC	Most widespread. Highest compatibility	YouTube, SNS, web
HEVC	H.265	~40% better compression than H.264	4K video, storage saving
VP9	—	Google-developed. Open source	YouTube (server-side), WebM
AV1	—	Next-gen. Best compression ratio	Future web delivery

Audio Codecs:

Codec	Key Feature	Primary Use
AAC	High quality, small files. Most universal	Video audio tracks
MP3	Widely supported. Slightly dated	Music distribution, podcasts
FLAC	Lossless compression. No quality loss	Music archival, pro use
Opus	High quality at low bitrates	WebM video, VoIP

How Containers and Codecs Relate

The key insight: containers and codecs are independent concepts.

For example, an "MP4 file" can contain different codecs:

MP4 container:
├── Video: H.264 or HEVC or AV1
└── Audio: AAC or MP3

Same MP4, different codecs = completely different quality and file sizes.

Major Containers in Detail

MP4 (.mp4)

The most recommended container overall.

✅ Plays on virtually all devices and platforms
✅ Supported by YouTube, TikTok, Instagram, X/Twitter
✅ Supports H.264, HEVC, AV1
❌ Limited subtitle track support

Rating: ★★★★★ Best for: SNS posts, web delivery, general video

MOV (.mov)

Apple's container format. The standard in Mac video production workflows.

✅ ProRes codec support (high-quality intermediate files)
✅ Perfect integration with Final Cut Pro
✅ Supports H.264, HEVC
❌ Slightly lower compatibility on Windows/Android

Rating: ★★★★☆ Best for: Mac video production, intermediate files, Apple ecosystem

MKV (.mkv)

Open source and the most flexible container available.

✅ Supports virtually all codecs
✅ Multiple audio and subtitle tracks
✅ Chapter support
❌ Not supported on some devices/platforms

Rating: ★★★☆☆ Best for: Archival, multi-audio/subtitle, PC environments

WebM (.webm)

Google's web-delivery focused container.

✅ VP9 and AV1 codec support
✅ High compression efficiency for web
✅ Open source
❌ Low compatibility on Apple devices

Rating: ★★★☆☆ Best for: Web delivery, browser playback, server-side

Video Codec Comparison

H.264 vs HEVC vs VP9 vs AV1

Feature	H.264	HEVC	VP9	AV1
Compression	★★★☆☆	★★★★☆	★★★★☆	★★★★★
Encoding Speed	★★★★★	★★★★☆	★★★☆☆	★★☆☆☆
Compatibility	★★★★★	★★★★☆	★★★☆☆	★★★☆☆
HW Encoding (Mac)	✅ Yes	✅ Yes	❌ No	❌ No
License	Paid	Paid	Free	Free

Which Codec Should You Choose?

When in doubt, go with H.264. It plays everywhere and encodes fast.

1080p and below, general use → H.264
4K video, want to save storage → HEVC
WebM container delivery → VP9
Maximum compression (time is OK) → AV1

Audio Format Selection

Audio Tracks in Video

For audio within video files, AAC is the optimal choice in almost all cases.

Codec	Bitrate Guide	Use Case
AAC 128kbps	General SNS posts	TikTok, Instagram, Shorts
AAC 192kbps	High-quality audio	YouTube, podcasts
AAC 256kbps	Maximum quality	4K video, music content

Audio-Only Files

When working with audio files only:

Format	Quality	File Size	Use Case
M4A (AAC)	◎ High	Small	Podcast distribution
MP3	○ Good	Small	Wide sharing
FLAC	◎ Lossless	Large	Music archival
OGG (Opus)	◎ High	Very small	Web delivery

Quick Reference: Best Format by Use Case

Use Case	Container	Video Codec	Audio Codec
YouTube upload	MP4	H.264 / HEVC	AAC
YouTube Shorts	MP4	H.264	AAC
TikTok	MP4	H.264	AAC
Instagram Reels	MP4	H.264	AAC
Website embed	MP4 / WebM	H.264 / VP9	AAC / Opus
Intermediate (Mac)	MOV	ProRes	PCM
Archive	MKV	HEVC	FLAC
Podcast	M4A	—	AAC 192kbps
Music distribution	MP3 / FLAC	—	MP3 / FLAC

Select output format or preset
Convert

Complex format decisions simplified — just pick a preset and optimal settings are applied.

Summary

Choosing the right video and audio format means matching the right combination to your use case.

Key Takeaways

Containers are "boxes," codecs are "compression methods" — separate concepts
When in doubt: MP4 + H.264 + AAC — the most universal combo
For 4K, use HEVC — dramatically reduces file size
Audio-only: M4A (AAC) or MP3 — choose based on distribution platform

When format conversion gets complicated, let DockBuddy Converter's presets do the thinking.
