How to add a transparent overlay in Premiere Pro
Premiere Pro reads the alpha channel in a ProRes 4444 file by itself, so an overlay exported that way goes on V2 above your footage and is transparent with no keying.
Premiere Pro is one of the editors that needs no green screen at all. Give it the right file and the graphic arrives already cut out, ready to sit over your footage on a track of its own — the only work is choosing that file and putting it on the right track.
Export ProRes 4444, not MP4
In the export panel, choose Premiere Pro under Where will you use this. The format becomes ProRes 4444 · transparent, a .mov file that carries an alpha channel: the per-pixel transparency an MP4 has no room for, which is why an MP4 of the same graphic arrives as a black rectangle.
The file is large next to an MP4, because ProRes is built to be edited rather than sent anywhere and throws very little away. What you upload to YouTube is Premiere's own export at the end, not this. Premiere reads ProRes on Windows as well as on a Mac. On a plan, a ProRes export is one of the month's 4K-and-ProRes allowance; a project unlocked on its own exports it as often as you need.
On V2, above the footage
Import it — File, then Import, or drag it into the Project panel — and drag it onto V2 over the clip on V1. Premiere reads the alpha channel on its own, so the Program monitor shows the graphic over your picture and nothing else.
Match the size before exporting rather than after. Pick Landscape (1920×1080) or Vertical (1080×1920) from the size button above the canvas so the file lands at the sequence's frame size. A smaller file can be fitted with Set to Frame Size, but that is Premiere enlarging a finished picture. Position, Scale and Opacity in Effect Controls work on it like any other clip.
When it arrives black, or with a halo
A black ground means Premiere has been told to ignore the alpha. Right-click the clip in the Project panel, choose Modify, then Interpret Footage, and make sure Ignore Alpha Channel is not ticked.
The same dialog explains a pale halo around soft edges or a glow. CtaYou writes straight alpha, not premultiplied, so the premultiplied option there should be off; read the other way, every half-transparent pixel is brightened, and the edge of the graphic shows it first.
Timing and sound
The animation enters and leaves by itself, so it needs no Cross Dissolve at either end — a dissolve on top of a built-in exit only muddies it. Trim nothing off the tail; the last second is usually the graphic leaving.
If the template has sound, the .mov carries it, and it lands on its own audio track under the clip. Lower it in the mix, or delete it if the graphic should stay silent. The file uses the project's frame rate, shown at the top of the export panel; Premiere conforms a different rate on its own, but matching your sequence keeps every frame.
Questions
- Why is my transparent video black in Premiere Pro?
- Either the file has no alpha channel — an MP4 never does — or Premiere is ignoring it. Export as ProRes 4444, and check Modify, then Interpret Footage, where Ignore Alpha Channel should be unticked.
- Which track does an overlay go on in Premiere Pro?
- Any video track above your footage. Premiere draws higher tracks over lower ones, so a graphic on V2 sits over the clip on V1, and a second graphic on V3 sits over both.
- Can I change the overlay's size and position in Premiere?
- Yes, with Position and Scale in Effect Controls, like any clip. Keep enlargement to a minimum by exporting at the sequence's size in the first place.
