Supported formats and quality options

Post.php supports a range of formats designed to cover both audio and video use cases. Below is a breakdown of the most common formats, including typical codecs, bitrates, and quality options. The exact options can vary depending on the source video and t

Audio formats

• MP3— Commonly encoded at 128 kbps, 192 kbps, or 320 kbps with a sample rate of 44.1 kHz or 48 kHz. MP3 is widely compatible with almost every device and player..
• AAC— Efficient, high‑quality audio at 128–256 kbps; a good choice for streaming devices and newer players..
• WAV— Lossless PCM audio; large file sizes but highest fidelity. Ideal for editing or archival purposes..

Video formats

• MP4 (H.264/AAC)— The most compatible video format, supporting resolutions from 144p to 1080p (and higher for some sources). Typical bitrates range from 1,000 kbps to 10,000 kbps depending on resolution and frame rate..
• WEBM (VP9/Opus)— An open format optimized for web playback, often offering good quality at modest file sizes, especially for 720p and 1080p content..
• MKV— Flexible container format for advanced users; support may depend on the player. We commonly provide MP4 as the default for broad compatibility..

Quality options and what they mean

Quality is a blend of resolution, bitrate, and codec efficiency. Here are typical choices you’ll see and what to expect:

• Audio quality(MP3, AAC, WAV): 128 kbps for basic listening on mobile, 192–320 kbps for clear playback on headphones or car speakers. WAV is lossless and best for editing..
• Video quality(MP4/WEBM): 240p, 360p, 480p, 720p, 1080p. Higher resolutions provide sharper detail but larger file sizes. Some videos offer higher than 1080p when available on YouTube..
• Frame rate and codecs: H.264 is the most compatible; newer videos may utilize H.265/HEVC or VP9 for better compression at similar quality, reducing file size for the same visual quality.

Technical details about the format you choose

Knowing the basics helps you pick the right output. Here are typical technical specs you might encounter:

• MP3: Codec – MPEG‑1/2 Audio Layer III; Bitrate – 128–320 kbps; Sample rate – 44.1 kHz or 48 kHz; Channels – 2 (stereo).
• AAC: Codec – Advanced Audio Coding; Bitrate – 128–256 kbps; Sample rate – 44.1/48 kHz; Channels – 2.
• WAV: Codec – PCM; Bitrate – depends on sample rate and bit depth; Commonly 44.1 kHz, 16‑bit; pure lossless audio; large file sizes.
• MP4: Video codec – H.264 or H.265 (HEVC) where supported; Audio codec – AAC or Opus; Bitrate – typically 1,000–10,000 kbps for 720p–1080p; Resolutions – 144p to 1080p, sometimes higher depending on source.
• WEBM: Video codec – VP9; Audio codec – Opus or Vorbis; Bitrate – similar ranges to MP4 for given resolutions; generally good compression.

Use cases: why you might choose a specific format

Different situations call for different formats. Here are common scenarios and the formats that fit best:

• Offline listening on mobile devices: MP3 at 128–192 kbps provides small file sizes with clear sound—great for commutes and workouts.
• Offline video playback on laptops: MP4 at 720p or 1080p for smooth playback on larger screens without excessive bandwidth requirements.
• Archival and editing projects: WAV or AIFF (if available) for lossless quality and maximum editing flexibility.
• Web embedding and streaming: WEBM with VP9 for compatible, efficient web playback when you publish online or share links.
