🔷 MOV to BMP with Go

Extract BMP images from MOV video files for thumbnails, previews, frames, and content workflows.

GoREST APIMOV → BMP

Use this guide to convert MOV to BMP with Go, then adapt the example to your own app, backend, or processing flow.

Overview

What this guide covers

Conversion path

Use Converterer to accept or prepare a MOV file, trigger a MOV to BMP job, and return the output to your app or workflow.

Go example

Start with the example on this page, then adapt auth, file handling, polling, and result delivery to your environment.

Production usage

This is best suited to backend jobs, async processing, content pipelines, and repeatable conversion flows rather than one-off browser scripting.

Quick start

Get a working example in place

Code example

MOV to BMP

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
    "io"
    "mime/multipart"
    "net/http"
    "os"
)

func main() {
    body := &bytes.Buffer{}
    w := multipart.NewWriter(body)
    f, _ := os.Open("input.mov")
    fw, _ := w.CreateFormFile("input", "input.mov")
    io.Copy(fw, f)
    w.WriteField("output_format", "bmp")
    w.Close()

    req, _ := http.NewRequest(
        "POST",
        "https://api.converterer.com/convert",
        body,
    )
    req.SetBasicAuth(os.Getenv("CONVERTERER_API_KEY"), "")
    req.Header.Set("Content-Type", w.FormDataContentType())

    res, _ := http.DefaultClient.Do(req)
    var task map[string]any
    json.NewDecoder(res.Body).Decode(&task)
    fmt.Println(task["id"])
    // Result lands at <your-destination>/<id>.bmp
}
