BMP to DivX Converter

Turn a BMP Image Into a DivX Clip: What This Tutorial Covers

A BMP is a single still picture and DivX is a video format, so this conversion does not simply "reformat" your image — it builds a short silent video clip that holds your bitmap on screen for a length of time you choose. This walkthrough is for anyone who needs a still photo to play on a DivX-certified DVD or media player, a CD-era set-top box, or a video timeline that will not accept an image. It covers the settings that genuinely change the result (duration, frame size, background colour, quality), what the .divx file actually contains, and where DivX loses badly to MP4.

How to Convert BMP to DivX

1. Upload Your BMP Files: Drag and drop your .bmp onto the page or click "Add Files." Several bitmaps can go in at once, and Merge strategy decides what happens next — Merge images stitches them into one sequence, Video per image gives each bitmap its own clip.
2. Set the Image Duration: In the advanced options, the Duration dropdown runs from 1/60s (single frame at 60fps) all the way to 10 seconds per frame. This is the most important control on the page: a bitmap has no inherent length, so whatever you pick here is the length of the clip.
3. Pick Frame Size and Quality: Under Video resolution, Keep original matches your bitmap's pixel dimensions, while Fixed Resolutions offers exact frames such as 1920 x 1080 (Full HD) or 1080 x 1080 (Square) and Preset Resolutions offers 144p through 4320p. Background Color — White unless you change it — fills any letterbox bars the aspect-ratio change leaves behind. Quality Preset opens on Very High (Recommended).
4. Convert and Download: Click "Convert" and download your .divx file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.

Walk-through: Getting the Duration and Frame Right

The output is a silent clip — a bitmap carries no audio, so there is nothing to encode on that side and nothing you can do about it here. Everything you control is about how one frame is presented over time.

With Merge images selected, total runtime is just the number of bitmaps multiplied by the per-frame duration — twelve bitmaps at 2 seconds each give a 24-second clip. A few more things worth knowing before you convert:

• If your BMP is not a standard video shape, pick a Fixed Resolution close to its aspect ratio. The image is scaled to fit and Background Color paints whatever is left over, so a tall bitmap in a 1920 x 1080 frame gets white pillars on either side unless you change that colour.
• If the bitmap is very large, remember it is uncompressed on the way up — roughly three bytes per pixel at 24-bit, so a 4000x3000 bitmap is about 36 MB of upload before any conversion happens.
• If the clip must stay small, shorten the Duration first and lower the resolution second; both cut far more than dropping the Quality Preset does.

Which Target Should a Still Image Actually Go To?

Common Errors and How to Fix Them

• "The clip is over before I see anything" — You chose a fractional Duration such as 1/24s, which produces exactly one frame. Raise Duration to whole seconds.
• "My player shows a blank frame with no picture" — The frame was probably scaled into a mismatched aspect ratio and pushed behind the letterbox bars. Switch Video resolution to Keep original, or pick a Fixed Resolution close to the bitmap's own shape.
• "There's no sound" — Expected. A bitmap has no audio, so the clip is silent by design; add a soundtrack afterwards in a video editor if you need one.
• "My phone or TV won't play the .divx file" — Most modern devices dropped native DivX and AVI playback years ago. Convert to BMP to MP4 instead.
• "The file is bigger than the original image" — MPEG-4 Part 2 is designed for moving footage, not one repeated frame, so a long high-resolution clip can easily exceed the source bitmap. Shorten the Duration or drop the resolution.
• "The bars around my image are the wrong colour" — Background Color is White unless you change it. Set it to Black, or to whatever your bitmap's edges match, before converting.

When This Doesn't Work

DivX in an AVI-style file is a legacy endpoint — it exists for DivX-certified DVD players and Xvid-era hardware that predate H.264, and it has no advantage on anything newer. If your target is a modern phone, browser, social platform, or editor, use BMP to MP4 for a clip that plays everywhere, or BMP to AVI if a tool specifically demands the AVI extension. If the goal is a looping animation on a web page rather than a video file, an animated image beats any video container for this job. And if you already have a DivX file you are trying to modernise, DivX to MP4 is the direction you want.

Frequently Asked Questions

Does converting BMP to DivX add sound?

No. A bitmap contains only pixels, so the resulting clip has no audio track at all — it is silent by construction, not by a setting you can flip. If you need sound, add it afterwards in a video editor, which is also where you would sync it to the image's on-screen time.

How long will the DivX video be?

Exactly as long as the Image Duration you choose, multiplied by the number of bitmaps if you selected Merge images. The dropdown spans a single frame (1/60s, 1/30s, 1/24s) up to 10 seconds per frame, so one bitmap at 5 seconds gives a 5-second clip and eight bitmaps at 5 seconds give 40 seconds.

What is actually inside the .divx file?

MPEG-4 Part 2 video — the Advanced Simple Profile codec that DivX 4, 5, and 6 popularised — carried in an AVI-structured file that uses the .divx extension, with no audio stream. The Video Codec control on this page lists DivX and nothing else, because that is the only sensible payload for this container. Note this is not the DivX Media Format that DivX 6 introduced for menus and multiple tracks; it is the plain codec-in-AVI arrangement DivX-certified players expect.

Is DivX still worth using instead of MP4?

Only for old hardware. DivX began as Jérôme Rota's "DivX ;-)" hack in the late 1990s, became a real product with DivX 4.0 in 2001, and is still maintained as consumer software by DivX, LLC — but the codec itself is MPEG-4 Part 2, a generation behind H.264. Phones, browsers, smart TVs, and editors all favour MP4 now. Pick DivX when a DivX-certified player is the destination; otherwise convert to MP4.

Why is my DivX clip larger than the BMP it came from?

Because video codecs spend bits per second, not per image. MPEG-4 Part 2 compresses by predicting motion between frames, and a still image gives it nothing to predict — so a ten-second 1080p clip stores ten seconds' worth of bitrate for a picture that never changes. Shorten the Duration, lower the resolution, or drop the Quality Preset a step to cap the result — file-size targeting modes don't appear for image sources.

What plays a .divx file on a computer?

VLC and the free DivX Player open .divx and .avi clips on Windows and macOS, and any player built on FFmpeg's demuxers will handle the file too. What generally will not play it: browsers, phones, and the built-in players on recent versions of Windows and macOS, all of which dropped native DivX support. That gap is the main reason MP4 is the safer choice for anything you intend to share.

Can I turn a folder of bitmaps into one slideshow clip?

Yes — that is what Merge strategy → Merge images does. Upload the bitmaps in the order you want them, choose a Duration for how long each one holds, and you get a single clip. Choosing Video per image instead gives you one separate .divx file per bitmap, which is what you want when the images are unrelated.

My bitmap isn't 16:9 — what happens to the shape?

The image is scaled to fit inside the frame you chose without distorting it, and the leftover area is filled with the Background Color, which is White unless you change it. A portrait bitmap in a 1920 x 1080 frame therefore gets white pillars either side. To avoid bars entirely, leave Video resolution on Keep original, or pick a Fixed Resolution with the same aspect ratio as your bitmap — there are square, vertical, and ultrawide presets in that list.

Are my uploaded files kept private?

Yes. Your bitmap is sent over an encrypted connection, converted on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark on the output, and files are never shared or made public.
