DivX to BMP Conversion FAQ
How do I extract individual frames from DivX as BMP images?
+
Upload the DivX 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 DivX video stream, encoded as a separate BMP file, and bundled as a ZIP for download. DivX names a codec rather than a container — an MPEG-4 Part 2 implementation that made ripping a DVD to a single CD possible around 1999. BMP is the Windows Bitmap, the raw raster format built into Windows since 1985.
Why do my extracted frames have horizontal lines through them?
+
Because the source is interlaced. DivX 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 BMP frames without the subtitles?
+
Only if the DivX never had them burned in, because DivX has no selectable subtitle stream to switch off. Anything a DivX shows on screen is in the picture itself, so it is in every BMP 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. DivX needs roughly twice the bitrate of H.264 for the same quality and has no path to HDR, 10-bit colour or resolutions beyond 1080p.
How big will the BMP files be?
+
Larger than you might expect, because BMP 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. BMP usually stores completely uncompressed pixel rows with a small header, which is why it is so simple to parse.
Will a very large DivX file upload successfully?
+
Free accounts cap at 100 MB per file, and DivX 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 BMP images come out?
+
Same resolution as the source DivX: a 1080p DivX produces 1920x1080 BMP frames, a 4K DivX produces 3840x2160 BMP 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 a DivX as BMP?
+
Yes, but mind the file count — a 30 fps 1-minute DivX produces 1,800 BMP 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 DivX at every-frame would produce ~100,000 BMP images.
Will the BMP frames preserve the DivX colour grading?
+
Yes — colour is decoded with the same matrix the source DivX stream advertises (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR when extracting to a BMP 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 BMP frame on disk?
+
Depends on resolution and BMP 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 DivX is roughly 50 GB and gets split across multiple ZIPs.
Does the extracted BMP keep camera EXIF metadata?
+
A DivX container does not carry per-frame EXIF the way a still camera does, so the BMP 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 DivX to BMP take?
+
Frame decoding is fast — typically 20-30% of source duration. A 5-minute DivX -> BMP bundle finishes in about 1 minute regardless of how many frames you pick, because the bottleneck is the BMP encoder writing many small files in parallel, not the DivX demuxer.
Can I extract frames at exact timestamps inside the DivX video?
+
Yes — the advanced timestamp option accepts a comma-separated list (e.g. `00:01:23, 00:05:00, 00:10:42.5`) and produces one BMP file per timestamp. Useful for chapter thumbnails, scene reference shots, or building a contact sheet for review.
