Same pictures.One trip.

Black Bars makes your thumbnails. Beat Videos makes your videos. Ship a batch through both and you run the same pictures twice, then match the files back up by hand. That second trip is the only thing this deletes. Drop the beats and the pictures once, check the pairs, and every beat comes back as "Midnight 140 Cm.mp4" and "Midnight 140 Cm.jpg": same name, same picture, both ready to upload.

Beat with no artwork? It makes a clean one from the name. Pictures with no beats? You get the thumbnails on their own.

Upload to more than one channel? Name it here before you pair, and every pair you make lands under that channel. Each channel downloads as its own zip, named after it. Leave it empty and nothing changes.

The picture punches on every kick. I listen to the sub-100 Hz of your own beat, so it lands on your drums. No tempo to type in, nothing to line up. Costs you: a slower render and a file around 3× bigger. Every frame moves now.

Skip this if you only want the videos. If you want them, I'll read the name, BPM and key off each beat and hand you a ready-to-paste YouTube title, description and pinned comment for every one. Fix any field above and it updates here.

I'll find the beat-name slot and swap in each beat's name.

Goes into every description and every pinned comment.

Pair a beat above and the copy shows up here.

Keep your presets?

Drop once.Get both files.

  1. Drop both

    Your thumbnails and your beats, whole folders welcome. I read each beat's name, BPM and key right off the file name. Got something that plays before the beat, a speech, a movie line, a clip? Drop it in the intro lane and it lands in front of every one.

  2. Pair and make

    Auto-pair by name, or click a beat and then a picture. Hit Make my batch. Your machine renders every MP4 and its matching JPG: no upload, no server, no watermark.

  3. Upload and done

    "Free Drake Type Beat - Midnight - 140 Cm.mp3" comes out as "Drake Midnight 140 Cm.mp4": the junk stripped, the name, BPM and key kept. Grab the matching titles, descriptions and pinned comments, paste, publish.

Whole Batch,answered.

Does it work on my phone?

Black Bars does. Beat Videos and the video half of Whole Batch need a laptop browser that can render video: Chrome, Edge or Safari. Whole Batch's thumbnails work anywhere.

How many files at once?

Black Bars takes up to ~300 pics a drop, subfolders included. Beat Videos takes whole folders of beats and covers.

Which file types?

Pics: JPG, PNG, WEBP, BMP, TIFF. Beats: MP3, WAV, M4A. Intros: MP3, WAV, MP4, MOV.

Do my files get uploaded anywhere?

No. The tools run in your browser, on your machine. Your beats and pics never leave it.

Is there a watermark?

No. Your videos and thumbnails come out clean.

Does it upload to YouTube for me?

The free tools don't. They hand you the files and the copy, ready for your upload.

Is it really free?

Yes. No card, no trial clock. A free account gets you the download.

Why do you want my email?

It is how your free account works and how the download reaches you. It goes to Kit, my email service. One click unsubscribes.

Rocket I built Black Bars for the thumbnails and Beat Videos for the videos, then sat there every week doing both: same pictures, two tools, two folders, then matching the files back up by hand. So I built the one that does the whole run. The other two aren't going anywhere. If you only need one of them, use that one.

One drop.Two outputs.
