FFmpeg 9.0.2 2026-10-19

Wonderful. I use it to run a Drag'n'Drop .bat script (created in chatGPT4) to convert any video format/codec to streaming FROM Telegram format without needing to download it from Telegram first. Copy below text to a .txt file on your desktop on PC only and rename the extension to .bat , then Drag'n'Drop your video onto it and it will convert automatically leaving the streaming version in the same folder as the original. Easier than Handbrake tool:

@echo off
setlocal enabledelayedexpansion

:: Drag-and-drop batch script for FFmpeg
:: Converts any video to Telegram-ready .mp4

if "%~1"=="" (
echo Drag and drop a video file onto this script to convert it.
pause
exit /b
)

set "input=%~1"
set "name=%~n1"
set "ext=%~x1"
set "dir=%~dp1"
set "output=%dir%%name%_telegram.mp4"

echo Converting "%input%" to "%output%"...
ffmpeg -i "%input%" -c:v libx264 -preset fast -crf 23 -c:a aac -b:a 128k -movflags +faststart "%output%"
echo Done!
pause
