Format comparison
For Premiere Pro and DaVinci Resolve, start with a PNG sequence; both document image-sequence workflows and preserve the exported alpha channel. For Final Cut Pro, use MOV with HEVC alpha or convert the PNG frames to ProRes 4444. For OBS and Streamlabs, WebM with alpha is the practical single-file choice. CapCut support varies by platform and version, so test a short PNG or WebM export before committing to a long render. The table below separates documented paths from formats that need verification in your exact setup.

|---|---|---|---|---|---|---|---|---|
| PNG sequencePNG image sequence (zipped) | Lossless | Native | Native | Works | Unreliable | Unreliable | Chrome, Edge, Firefox, Safari | The safest browser export for professional editing. Premiere Pro and DaVinci Resolve document image-sequence import, and PNG preserves lossless transparency. |

File-size and export-time benchmarks are measured per release and published here once recorded.
Pick this first for Premiere or Resolve. For Final Cut, convert it to ProRes 4444 when you want one timeline-ready file.
Best for: The safest browser export for professional editing. Premiere Pro and DaVinci Resolve document image-sequence import, and PNG preserves lossless transparency.
Watch out: It is a folder of frames rather than a single clip. Final Cut and CapCut may require a different still-image or conversion workflow, so verify timing before a deadline.
The fast single-file path for streaming. For editing, use PNG or a documented professional codec.
Best for: Quick streaming overlays. Drops into OBS and Streamlabs as a Media Source with the background already cut out, and plays back cheaply.
Watch out: More compressed alpha edges than VP9. Adobe, Blackmagic, and Apple documentation do not establish this WebM-alpha file as a dependable native editing path.
Use it for OBS when file size matters. Use PNG or ProRes 4444 for a professional editing handoff.
Best for: A smaller single transparent video file for OBS and browser-based workflows where VP9 alpha has been tested.
Watch out: Cannot be exported in Safari. Native alpha import is not documented as a dependable route in Premiere Pro, DaVinci Resolve, or Final Cut Pro.
The right direct single-file format for Final Cut on a supported Mac. Elsewhere, use PNG or convert to a documented codec.
Best for: Apple workflows. Apple documents HEVC with alpha as a transparent media path for Final Cut Pro.
Watch out: Can only be exported from Safari 17.4+ on macOS. Treat Premiere, Resolve, and CapCut compatibility as version-dependent until tested locally.
Use only when you need a true lossless master in a pro editor. Otherwise the PNG sequence is enough.
Best for: A lossless alpha master inside Premiere, DaVinci, or Final Cut, converted from a PNG sequence with the bundled script.
Watch out: Not a direct browser export and very large on disk. Not meant for CapCut or live streaming software.
A PNG sequence is the safest direct browser export for editing, and Premiere Pro and DaVinci Resolve document image-sequence workflows. For a single professional editing file, convert the frames to ProRes 4444. Final Cut users on supported Macs can also choose MOV with HEVC alpha.
On a supported Mac, use MOV with HEVC alpha or convert the PNG sequence to ProRes 4444 for Final Cut Pro. Apple documents both codecs as supporting alpha. Do not depend on a WebM-alpha editing workflow unless you have tested it in your exact version.
Export WebM (with alpha) for OBS or Streamlabs and add it as a Media Source. If playback is heavy, make a shorter overlay or reduce resolution and frame rate, then verify looping and transparency in a test scene.
Only when you need a lossless alpha master inside a professional editor. ProRes 4444 is converted from the PNG sequence with the bundled ffmpeg script. For most edits, the PNG sequence itself is already lossless and sufficient.
