AVI to PNG Conversion FAQ
How do I extract individual frames from AVI as PNG images?
+
Upload the AVI file and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is decoded from the AVI video stream, encoded as a separate PNG file, and bundled as a ZIP for download. AVI is Microsoft’s Audio Video Interleave, introduced in 1992 on top of the RIFF chunk format — one of the oldest containers still in circulation. PNG was designed in 1996 as a patent-free replacement for GIF, and became the web’s default lossless image format.
Why do my extracted frames have horizontal lines through them?
+
Because the source is interlaced. AVI content from the broadcast and DVD era stores two half-height fields per frame, captured a fiftieth of a second apart, and a still pulled straight out shows both woven together as combing on anything that moved. Enable deinterlacing before extraction and each still is built from a single reconstructed progressive frame.
Can I get the PNG frames without the subtitles?
+
Only if the AVI never had them burned in, because AVI has no selectable subtitle stream to switch off. Anything an AVI shows on screen is in the picture itself, so it is in every PNG the extraction produces and no setting removes it afterwards. Where a separate subtitle file exists alongside the video, extract from a source that kept the two apart and the frames come out clean. AVI has no native support for modern codecs, variable frame rate, soft subtitles or files over 4 GB without hacks, and its per-chunk overhead bloats the file.
Does the PNG output support transparency?
+
The format does, but the source has no alpha to give it — video frames and rendered pages are fully opaque by nature, so every pixel arrives solid. The alpha channel is still useful afterwards: it means you can cut a subject out of the PNG later without changing format again. PNG is the right choice for screenshots, logos, line art and anything with hard edges or transparency — no ringing, no colour banding.
How big will the PNG files be?
+
Larger than you might expect, because PNG keeps every pixel exactly rather than approximating. A 1080p still lands around 2-5 MB and a 4K still around 6-15 MB, so a long extraction run adds up quickly. That is the right trade when the images feed further processing, and the wrong one when they are going straight onto a web page. PNG uses DEFLATE compression over filtered scanlines, so every pixel survives exactly, plus a full 8-bit alpha channel.
Will a very large AVI file upload successfully?
+
Free accounts cap at 100 MB per file, and AVI sources run large because the format carries substantial per-chunk overhead on top of the video data. Premium lifts the cap considerably. If the file is split into numbered parts because of the format ceiling, upload them together and they are treated as one job.
At what resolution do the extracted PNG images come out?
+
Same resolution as the source AVI: a 1080p AVI produces 1920x1080 PNG frames, a 4K AVI produces 3840x2160 PNG frames. The converter does not upscale or downsample — pixel dimensions are pulled straight from the decoded frame. Use /resize-image/ after extraction if you need smaller thumbnails.
Can I extract every frame of an AVI as PNG?
+
Yes, but mind the file count — a 30 fps 1-minute AVI produces 1,800 PNG frames. We pack them into a single ZIP archive automatically. For longer clips, prefer the "1 per second" preset (60 frames per minute) or pick specific timestamps. An hour of AVI at every-frame would produce ~100,000 PNG images.
Will the PNG frames preserve the AVI colour grading?
+
Yes — colour is decoded with the same matrix the source AVI stream advertises (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to a PNG that cannot store HDR pixel ranges natively (JPG, PNG-8). Target high-bit PNG-16 or TIFF if you need to keep extended dynamic range.
How big is one extracted PNG frame on disk?
+
Depends on resolution and PNG codec choice: a 1080p PNG frame is 2-5 MB lossless, a 1080p JPG at quality 85 is 200-500 KB. Multiply by frame count to size the ZIP — at the extreme, every-frame PNG extraction of a 10-minute 1080p AVI is roughly 50 GB and gets split across multiple ZIPs.
Does the extracted PNG keep camera EXIF metadata?
+
An AVI container does not carry per-frame EXIF the way a still camera does, so the PNG files come out with empty EXIF blocks. The converter does embed a `creation_time` field pointing at the source frame timestamp, so you can re-sort the bundle in chronological order or correlate with subtitle / chapter markers.
How long does frame extraction from AVI to PNG take?
+
Frame decoding is fast — typically 20-30% of source duration. A 5-minute AVI -> PNG bundle finishes in about 1 minute regardless of how many frames you pick, because the bottleneck is the PNG encoder writing many small files in parallel, not the AVI demuxer.
