BigicloudTV Video Optimization Tool

This guide explains how to use the automated video converter to prepare your videos for upload to the BigicloudTV platform. This tool automatically:

• Resizes video to 720p (HD).
• Adds your logo to the top right corner.
• Compresses the video to a strict bitrate (2Mbps total) to ensure smooth streaming.

Part 1: Windows Users

1. Initial Setup (One-Time Only)

The script requires a tool called FFmpeg. Follow these steps carefully:

1. Click here to download FFmpeg (Windows).
2. Extract the downloaded ZIP file.
3. Open your C: Drive (C:\).
4. Create a new folder named ffmpeg.
5. Copy the contents of the extracted folder so that the bin folder is located strictly at:
   C:\ffmpeg\bin\
   Verification: You should see the file ffmpeg.exe inside that folder.

2. Create the Script

Open Notepad and copy the code below. Save the file as convert_all.bat (ensure "All Files" is selected in the save dialog so it doesn't end with .txt).

@echo off
setlocal enabledelayedexpansion

REM === Path to ffmpeg ===
set FFMPEG=C:\ffmpeg\bin\ffmpeg.exe
set LOGO=%~dp0logo.png

REM === Encoding settings (Strict ~2Mbps Total Limit) ===
REM Video (1800k) + Audio (128k) + Overhead ~= 2000k Total
set TARGET_BITRATE=1800k
set MAX_BITRATE=1800k
set BUF_SIZE=3600k
set AUDIO_BITRATE=128k

cd /d %~dp0

set OUTPUT=%~dp0converted
if not exist "%OUTPUT%" mkdir "%OUTPUT%"

for %%a in (*.mp4) do (
    echo Processing: %%a

    "%FFMPEG%" -i "%%a" -i "%LOGO%" -filter_complex ^
    "[0:v]scale=1280:720[bg];[1:v]scale=70:-1[logo];[bg][logo]overlay=W-w-40:40" ^
    -c:v h264_nvenc -preset p5 ^
    -profile:v high -level 4.0 -pix_fmt yuv420p ^
    -b:v %TARGET_BITRATE% -maxrate %MAX_BITRATE% -bufsize %BUF_SIZE% ^
    -r 30 -g 60 -keyint_min 60 -sc_threshold 0 ^
    -c:a aac -ar 48000 -b:a %AUDIO_BITRATE% ^
    -movflags +faststart ^
    -y "%OUTPUT%\%%~nxa"
)

echo.
echo Done! BigicloudTV optimized files created.
pause

3. Preparing Your Folder

1. Create a folder on your Desktop (e.g., "BigicloudTV_Convert").
2. Place the convert_all.bat file (that you just created) in this folder.
3. Add Your Logo:
   • Copy your logo image into this folder.
   • Crucial Step: You must rename your logo file to logo.png. The script will only look for a file with this exact name.
4. Copy all the .mp4 videos you want to convert into this same folder.

4. Running the Converter

1. Double-click convert_all.bat.
2. A window will open showing the progress.
3. Once finished, a new folder named converted will appear containing your BigicloudTV-ready videos.

5. Customization & Troubleshooting

Right-click convert_all.bat and select Edit to change settings.

Changing Resolution (720p to 1080p)
By default, the script outputs 720p. To switch to Full HD (1080p):

• Find: scale=1280:720
• Replace with: scale=1920:1080

Switching from GPU to CPU (If the script crashes)
By default, the script uses NVIDIA GPU acceleration. To use standard CPU mode:

• Find: -c:v h264_nvenc -preset p5 ^
• Replace with: -c:v libx264 -preset fast ^

Changing Quality (Bitrate)
Find set TARGET_BITRATE=1800k and increase it (e.g., to 3000k) if your BigicloudTV plan supports higher quality.

Part 2: Mac Users

MacOS cannot run .bat files. Please use the script below.

1. Install FFmpeg on Mac

1. Open the Terminal app.
2. Install Homebrew if needed, then type: brew install ffmpeg

2. Create the Mac Script

Create a text file named convert_for_bigicloud.sh with the following content:

#!/bin/bash

# Settings for BigicloudTV
TARGET_BITRATE="1800k"
MAX_BITRATE="1800k"
BUF_SIZE="3600k"
AUDIO_BITRATE="128k"
LOGO="logo.png"

# Create output folder
mkdir -p converted

# Loop through all MP4 files
for f in *.mp4; do
    echo "Processing for BigicloudTV: $f"
    
    ffmpeg -i "$f" -i "$LOGO" -filter_complex \
    "[0:v]scale=1280:720[bg];[1:v]scale=70:-1[logo];[bg][logo]overlay=main_w-overlay_w-40:40" \
    -c:v libx264 -preset fast \
    -profile:v high -level 4.0 -pix_fmt yuv420p \
    -b:v $TARGET_BITRATE -maxrate $MAX_BITRATE -bufsize $BUF_SIZE \
    -r 30 -g 60 -keyint_min 60 -sc_threshold 0 \
    -c:a aac -ar 48000 -b:a $AUDIO_BITRATE \
    -movflags +faststart \
    -y "converted/${f%.*}.mp4"
done

echo "Done! BigicloudTV optimized files created."

3. Running on Mac

1. Put the script, logo.png, and videos in one folder.
2. Open Terminal, type cd (with a space) and drag the folder into the window. Hit Enter.
3. Type chmod +x convert_for_bigicloud.sh to make it executable.
4. Run it by typing ./convert_for_bigicloud.sh
5. Note: To change resolution on Mac, edit the file and change scale=1280:720 to scale=1920:1080.
