Need help?APNG to AVCHD Converter
APNG (Animated PNG) is a lossless, frame-based image format with full transparency; AVCHD is the HD camcorder and Blu-ray authoring format Sony and Panasonic built around H.264 video in an MTS/M2TS transport stream. Converting an animation into AVCHD is unusual — AVCHD is meant for camcorder footage and disc authoring, not web animations — so if your goal is simply a playable video file, convert APNG to MP4 instead. This converter exists for the narrow case where you genuinely need an AVCHD-structured clip for a disc-authoring or camcorder-editing workflow. Note that AVCHD video carries no alpha channel, so any transparency in your APNG is flattened onto the background color you choose.

How to Convert APNG to AVCHD
- Upload Your APNG File: Drag and drop your animated PNG onto the page or click "Upload." You can add several files at once.
- Pick a Merge Strategy: Choose "Merge images" to combine multiple uploads into one AVCHD clip, or "Video per image" to get a separate file for each.
- Set Image Duration, Background Color, and Quality Preset: Image Duration controls how long each frame is shown; Background Color fills the area where the APNG was transparent (default black); the Quality Preset defaults to "Very High."
- Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.
Frequently Asked Questions
Is APNG to AVCHD a sensible conversion, or should I use MP4 instead?
For almost everyone, MP4 is the better target. AVCHD is a camcorder and Blu-ray authoring format — its value is being editable in tools like Sony Vegas or PowerDirector and burnable to disc without re-encoding. If you just want a shareable, broadly playable video of your animation, convert APNG to MP4; both use H.264, but MP4 plays everywhere with no disc-authoring overhead.
What happens to my APNG's transparency in AVCHD?
It is flattened. AVCHD stores H.264 video, which has no alpha channel, so any transparent pixels are filled with the Background Color you select (black by default). If preserving transparency matters, AVCHD — and any standard video format — is the wrong destination; keep the file as APNG or WebP.
Will the output AVCHD have sound?
No. APNG is an image format with no audio track, so the resulting AVCHD is silent. The converter still writes an AC-3 audio configuration because AVCHD players expect it, but there is nothing to encode unless you add audio in a later editing step.
How does Image Duration affect the AVCHD clip?
Image Duration sets how long each frame of your APNG is displayed in the output. In our testing, a 12-frame APNG at the "1/24s (single frame at 24fps)" setting produced a roughly half-second clip, while "1 second per frame" stretched the same 12 frames to a 12-second video. Pick a short per-frame duration to keep the animation playing at its original speed.
Does the AVCHD file follow the full BDMV disc folder structure?
No. This tool outputs a single H.264-in-MPEG-transport-stream file using AVCHD's .mts/.m2ts encoding, which imports into editors and disc-authoring software. It does not generate the full BDMV directory tree that a camcorder writes to a memory card or that a Blu-ray needs at the root — your authoring application builds that structure when you finalize a disc.
What resolution and frame rate should I pick for AVCHD?
AVCHD is defined around HD frame sizes — 720p, 1080i, and 1080p — so leave the resolution at an HD preset such as 1920×1080 for the cleanest compatibility with camcorder editors and players. Setting a non-standard size can produce a file that plays in VLC but is rejected by stricter AVCHD-only software.
What software opens an AVCHD file once I download it?
VLC, Adobe Premiere Pro (CS4 and later), Sony Vegas, and CyberLink PowerDirector all read AVCHD, as do PlayStation 3 and many Blu-ray players. On a plain desktop without those tools, an .mts file may not open in the default photo or media viewer, which is another reason most users are better served by MP4.
