M4V to PNG Conversion FAQ
How do I extract individual frames from M4V as PNG images?
+
Upload the M4V and open the options. Frame Extraction has two modes: Single Frame saves one PNG from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a PNG image. There is no every-Nth-frame or one-per-second mode. M4V is Apple’s variant of MP4, used by iTunes and the Apple TV app for films and TV episodes. PNG was designed in 1996 as a patent-free replacement for GIF, and became the web’s default lossless image format.
Will subtitles show up in the PNG frames I extract?
+
Not if they are a real subtitle track. An M4V keeps subtitles as their own stream and the player draws them over the picture at playback time, so the decoded frame the converter writes out as a PNG has clean pixels underneath. Subtitles that were burned into the video before it ever became an M4V are a different matter — by then they are part of the image and every extracted frame keeps them.
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.
At what resolution do the extracted PNG images come out?
+
Same resolution as the source M4V: a 1080p M4V produces 1920x1080 PNG frames, a 4K M4V 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 M4V as PNG?
+
Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 PNG images. For a single still, choose Single Frame and enter the second you want instead.
Will the PNG frames preserve the M4V colour grading?
+
HDR footage is not tone-mapped: each frame is converted from the M4V as it is decoded, so a frame from an HDR M4V can look flat or washed out as a PNG. Standard (SDR) video keeps its colours.
How long does frame extraction from M4V to PNG take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Is my M4V private during frame extraction?
+
Yes. Uploaded M4V files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
