Built withElectronTypeScriptReactWebGL2FFmpegwhisper.cpp
OVERVIEW
About the Reelsaz project
Reelsaz is an installable Windows app for Persian-speaking content creators. Raw footage — for example someone talking to camera — goes in, and Reelsaz writes word-by-word Persian subtitles, cuts silences and pauses, and adds animated captions, colour, effects and sound to deliver a reel that is ready to post.
All processing happens on the user's own computer: nothing is uploaded, no internet connection is needed, and the export is tuned so the video still looks sharp after Instagram's compression.
Challenge
Well-known video editors either render Persian incorrectly (broken, reversed letters), need an online service and a foreign-currency subscription for subtitles and silence removal, or are so complex that a simple reel takes hours. Video exported with ordinary settings also turns blurry and washed-out after uploading to Instagram.
Solution
A complete editor was built for Persian from the ground up: a dedicated Persian text engine for captions, offline speech recognition for subtitles, automatic removal of silences and filler words, and a deterministic render engine so the preview and the export are identical. Export settings were chosen specifically for Instagram so quality survives compression.
