How to film stock footage with your iPhone

This is the guide I wanted when I started. It explains what stock footage is, how BlackBox Global works, how to film with an iPhone so the clips are accepted, and what the money looks like in reality. It follows the BlackBox Success Guide, which every member has to read anyway. I am a contributor and I build a free iPhone app for the technical part, so the app appears in one section below. Everything else works without it.

What stock footage is and who pays for it

Stock footage is short video clips that other people license for their own projects: adverts, YouTube videos, corporate films, news, documentaries, TV series. A clip is one continuous shot, usually 10 to 15 seconds long, with no sound and no editing. The buyer pays the agency, the agency pays the contributor a share, and the same clip can sell many times over several years.

BlackBox Global is a distributor. You upload a clip once, and BlackBox sends it to Shutterstock, Pond5, Adobe Stock, iStock, DepositPhotos, Freepik, Envato and Canva. Membership is free. When a clip sells, BlackBox keeps 15% of the net sale and pays the rest to you by PayPal on the 20th of the month, after your balance reaches $10. PayPal takes its own fee from the payment.

The realistic timeline, from the BlackBox FAQ: clips are normally online for one to three months before the first sale, and steady sales usually begin around 500 clips of professional quality. BlackBox's record is one clip that made over $20,000 in four years. That is the exception. Most clips sell for a few dollars, some never sell, and a few sell again and again. Quality and variety decide it. BlackBox says a hundred excellent clips outsell a thousand average ones.

Two things to know before you start. Clips appear on the agencies under the name BlackBoxGuild. BlackBox does not report which agency sold a clip or which agency rejected it. People who want their own name on the agencies and detailed statistics usually upload to the agencies directly. BlackBox suits people who want to upload once and let someone else handle eight agencies.

How to film so BlackBox accepts it

BlackBox reviews every clip before it goes to the agencies, and the agencies review it again. The technical rules are strict and the quality rules are stricter. BlackBox says plainly that it is not looking for home video. An iPhone can produce clips that pass, but only if you treat it like a camera.

1. Use a manual camera app. The built-in Camera app changes exposure, focus and white balance while recording, and that ruins a stock clip. Use an app with manual controls, for example Blackmagic Camera (free) or Filmic Pro. Lock exposure, focus and white balance before you press record.
2. Set a fixed frame rate and resolution. Film in 4K or 1080p at 25 or 30 fps. BlackBox accepts 23.98, 24, 25, 29.97, 30, 50, 59.94 and 60 fps. The iPhone records at a variable frame rate by default, which the BlackBox portal rejects. The fix is in the upload section below.
3. Keep the phone still. Use a tripod or a gimbal. Shaky footage is the same rejection on a phone as on a cinema camera. The built-in stabilisation of the phone often adds a wobble that reviewers call the jello effect, so mount the phone instead of relying on it.
4. Film in good light only. Noise is the number one rejection reason at the agencies. A phone sensor is small. Film at sunrise, at sunset, in daylight and in well-lit interiors. Dusk, night and dim rooms produce the noise that reviewers reject.
5. Use an ND filter in daylight. With a fixed shutter speed, bright light needs a neutral density filter to keep the exposure right. A clip-on ND filter for the iPhone costs less than a tripod.
6. No digital zoom. Zooming in on a phone crops the sensor and adds noise. Move closer or use a different lens.
7. One continuous shot, 10 to 15 seconds. Deliver the raw shot without cuts, transitions, music or titles. Sound is not needed, because the uploaded clip has no audio track. BlackBox accepts 5 to 59 seconds, and says 10 to 15 second clips sell best. Start recording two seconds early and stop two seconds late, then trim.
8. Check the clip on a big screen. The phone screen hides noise, soft focus and rolling shutter. BlackBox recommends checking clips on a laptop or monitor before upload. Delete anything you are not sure about.
9. People and property need releases. A recognisable person needs a model release. Private property, artwork and logos need a property release. BlackBox accepts digital releases from the Easy Release app. Footage of people doing everyday things is in high demand, and the release is the price of that demand.

What to film: BlackBox says the agencies have enough scenic and aerial shots, and that well-produced, authentic footage of people is what sells. Everyday life, work, cooking, commuting, sport, hobbies. Shoot what you have access to and what you can do well.

Check your gallery first

Some clips you already have will pass. Go through your photo library with this list and keep only the clips where every answer is yes:

• The camera was still, on a tripod or held steady with no walking.
• The light was good and the dark areas are clean, with no noise.
• Exposure and focus did not change during the clip.
• It is one continuous shot of at least 5 seconds.
• No recognisable faces, number plates, logos or artwork, or you can get a release.
• The clip is not already on Shutterstock, Pond5, Adobe Stock or another agency under your own account.

Expect to keep a small number. That is normal. The point of the check is to learn what passes before you go out and film more.

Drone pilots

Drone footage goes through the same review. The extra work is getting the file to the phone: download the clip from the drone app to your photo library, or use a card reader and the Files app. From there the upload works the same as for iPhone clips, so you can prepare and upload a day's footage from the hotel in the evening without a laptop.

Two BlackBox rules matter here. Accounts created after 15 April 2025 can upload 50 clips a week, so a big trip needs a few weeks of uploads. And BlackBox is not a regulator: local flight rules and permissions are your responsibility, and a clip filmed where drones are not allowed can bring problems later.

Create the BlackBox account

1. Register at blackbox.global. Membership is free. One account per person.
2. Read the Terms of Service and the Success Guide. BlackBox calls the guide mandatory, and it is long. Read it anyway. Most account problems come from people who did not.
3. Enter your PayPal address during registration and confirm it later in My Settings. This is where the money goes.
4. Wait for the approval email. The BlackBox website says to start uploading once you are approved, and BlackBox reviews every clip after that.
5. Find your FTP credentials in the portal. Uploads go over FTP to the BlackBox server, and the portal shows the host, user name and password for your account.

Prepare and upload the clips

The portal checks every file. The most common technical rejection for iPhone footage is the frame rate: the phone records at a variable frame rate, so a clip labelled 30 fps is really 29.9-something, for example 29.95, and the portal rejects it. The real rejection emails are on the rejections page. The other checks are resolution, no audio track, duration between 5 and 59 seconds, and file size.

On a desktop you can fix this with any editor or encoder that exports at a constant frame rate, strips the audio, and trims the clip. On the phone, this is what Brollr does: pick clips from the photo library or share a file from the Files app, trim, and the app re-encodes the clip to a constant supported frame rate, removes the audio, checks the resolution and size, and uploads the batch over FTP to the portal. This part is free and needs no sign-up. The app also has optional AI keywording that writes a title, description and keywords for a clip, as a paid add-on with 5 free credits every month. You can ignore it and write the metadata yourself in the portal.

After the upload, the clips appear in your BlackBox workspace. Add the title, description and keywords there, mark editorial clips as editorial, attach releases, and press Submit. BlackBox asks you to process uploaded clips within 30 days.

What happens after Submit

The clip shows as Pending Review while BlackBox checks it, then Ready when it has been sent to the agencies, then Online when at least one agency has accepted it. BlackBox normally sends clips to the agencies within one to three days. Agency review takes days to weeks. A clip rejected by BlackBox comes back with an email and a short reason, and you can fix the problem and upload it again. A clip rejected by all agencies shows as Rejected without an email, and BlackBox does not allow resubmitting the same clip with small changes.

Sales notifications arrive by email and in the My Earnings area of the portal. Subscription sales from the agencies that sell by subscription are reported about 60 days later as a monthly total. The payment arrives by PayPal on the 20th of the following month.
