Time Overlay guide
Convert Time Overlay PNG sequence to ProRes 4444 with alpha
ProRes 4444 keeps your alpha and color quality in a single file editors prefer. The Time Overlay PNG sequence export already ships with a conversion script that does this for you on macOS, Linux, and Windows.
Recommended Time Overlay export: PNG sequence export, then convert with ffmpeg.
Step 01
Install ffmpeg
macOS: `brew install ffmpeg`. Windows: download from ffmpeg.org and add the bin folder to PATH. Linux: `sudo apt install ffmpeg` or your package manager equivalent.
Step 02
Download the Time Overlay PNG sequence
Export 'PNG Sequence' from the Time Overlay generator. The downloaded zip includes the frames plus `convert-to-prores.sh`, `convert-to-prores.bat`, and a README.
Step 03
Run the bundled script
Unzip the archive. On macOS or Linux, run `./convert-to-prores.sh` from a terminal. On Windows, double-click `convert-to-prores.bat`. The script writes `output.mov` next to the frames.
Step 04
Manual one-liner if you prefer
Run `ffmpeg -framerate 30 -i frame-%04d.png -c:v prores_ks -profile:v 4444 -pix_fmt yuva444p10le output.mov` from inside the frames folder.
Time Overlay tips
ProRes 4444 alpha is large but lossless. Use it as a master, then transcode for delivery if file size matters. Premiere, DaVinci, and Final Cut all import this file as transparent media without further setup.
