# Membuat edit video xAI

> Gunakan POST /grok/v1/videos/edits untuk mengedit video sumber dengan prompt teks, mempertahankan gerakan, dan mendapatkan request_id untuk polling hasil async.

Gunakan endpoint ini untuk mengedit MP4 yang sudah ada dengan instruksi teks. Hasil output akan tetap lebih dekat dengan timing dan komposisi klip sumber dibandingkan permintaan generasi baru.

## Sebelum Anda mengirim permintaan

* Sediakan `video.url` yang dapat diakses
* Jaga agar klip sumber tetap pendek; panduan xAI sendiri membatasi edit hingga sekitar 8,7 detik
* Gunakan instruksi yang terfokus dan menjelaskan satu perubahan yang jelas
* Simpan `request_id` yang dikembalikan, karena edit menggunakan alur polling yang sama seperti generasi

## Alur pengeditan

<Steps>
  <Step title="Kirim permintaan edit">
    Kirim URL video sumber, prompt edit, dan `model: grok-imagine-video`.
  </Step>

  <Step title="Poll untuk hasil akhir">
    Panggil [Get xAI video results](./get-video-generation-results) sampai pekerjaan selesai.
  </Step>

  <Step title="Simpan aset yang telah diedit">
    Unduh output yang sudah selesai atau pindahkan URL yang dikembalikan ke pipeline penyimpanan Anda sendiri.
  </Step>
</Steps>

## Apa yang berubah di CometAPI

xAI mendokumentasikan pengeditan video sebagai lifecycle async yang sama seperti generasi, hanya saja menggunakan video sumber alih-alih gambar sumber opsional. CometAPI mempertahankan perilaku tersebut dan endpoint polling yang sama, sehingga workflow edit Anda tetap start -> poll -> download.
