Capsai Smart Compress at No. 1
use Capsai’s AI‑optimized compression presets to shrink file size with perceptual quality retention - no manual bitrate guessing.
- Upload your video at https://capsai.co/
- Select “Smart Compress” and choose target size or device profile
- Preview quality slider (HD, SD, Mobile), then click “Compress All”
- Download your compressed file ready for upload
HandBrake CLI
scriptable encoder with RF‑based quality control.
for f in *.mp4; do
HandBrakeCLI -i "$f" -o "compressed/${f%.*}-hb.mp4" \
--preset="Fast 1080p30" --quality=20
done
- RF 18–22 yields near‑lossless results; lower RF = higher quality
- Use
--two-pass
for better bitrate distribution if file size target matters
FFmpeg Two‑Pass Encoding
industry‑standard CLI for fine‑tuned compression.
ffmpeg -i input.mp4 -c:v libx264 -b:v 2000k -pass 1 -an -f mp4 /dev/null && \
ffmpeg -i input.mp4 -c:v libx264 -b:v 2000k -pass 2 -c:a aac -b:a 128k output.mp4
- Adjust
-b:v
(video) and-b:a
(audio) to match your bandwidth/size needs - Add
-preset slow
or-preset medium
for better compression efficiency
VLC Media Player
GUI‑driven tool with simple conversion profiles.
- Open VLC → Media → Convert/Save → Add your file
- Click “Convert,” choose “Video – H.264 + MP3 (MP4)” profile
- Click the wrench icon → Video codec → set Bitrate (e.g. 2000 kb/s)
- Save profile and export compressed clip
Avidemux
lightweight editor with fast recompression.
- Open video, set Video Output to “Mpeg4 AVC (x264)”
- Click Filters → Transform → Crop/Resize if needed
- Under Output Format, choose “MP4 Muxer” → Save → enter filename
- In Configure: set bitrate or use “Constant Rate Factor” ~23 for quality
Shotcut

- Import your clip, then click Export → Advanced → Codec tab
- Select H.264, set Rate Control to “Quality-based VBR,” Quality slider ~30%
- In Audio, choose AAC, Bitrate 128k → Export File
Shutter Encoder
free GUI leveraging FFmpeg & x264/x265.
- Launch Shutter Encoder, drag your video into the window
- Under Mode, pick “Codec,” then choose “H.265 – HEVC (x265)” or “x264”
- Click the gear icon → adjust CRF (18–23 for near‑lossless)
- Press Start Encoder and grab compressed output
Vikoders’s MPEG‑4 Compressor
web‑based quick compress with drag‑and‑drop.
- Go to https://www.compressvideo.online
- Drop your file, select target resolution (720p, 480p) and quality slider
- Click Compress, then download the result
Pick the workflow or tool that suits your batch size and tech comfort - each delivers high‑quality compression without visible degradation.
