Compressor UI (Go, Tauri, SvelteKit & Tailwind)

Compress videos using highly efficient & modern codecs (hardware accelerated) 🚀

My two motivations for this project:

• Learning Tauri & SvelteKit and Go
• I've tried many video compressors, but some were quite clunky and not user-friendly, others didn't support newer codecs and hardware acceleration. I wanted to create a simple and easy-to-use video compressor that anyone can use.

Todo

• HEVC + AMF (AMD hardware acceleration)
• Windows support
• View input & output file info/metadata
• Progress bar, estimated time, FPS, realtime log
• Estimate file size before compression
• Batch processing
• NVIDIA hardware acceleration
• Add more codecs
• Linux

Development

Benchmarks

Street at Night: 50MB/s 4K60 AVC Main@L5.2

I downloaded the source video and cut it to be 99.9 MiB (16s, 717ms). Quality tests were done with MSU_VQMT_14.1r12839_free_64, metric Netflix VMAF, color Y, colorspace auto YUV.

System:

• RX 6750 XT 12 GB GDDR6
• 32GB RAM @ 3200 MHz
• Ryzen 5 5600X
• Windows 11

Presets are my own collections of arguments I built into this program, NOT FFmpeg/encoders preset option! "No" means that the only FFmpeg arguments used are the ones to set the codec, bitrate and to encode the audio in 64k Opus.

Preset (Bitrate)¹	Bitrate²	File Size	VMAF (mean)³	Encoding Time
No 4000	5.0	10.2 MiB	59.71	11.34s
UltraSlow 4000	6.1	12.2 MiB	64.42	81.95s
Optimal 800-1600	15.7	32.0 MiB	79.241	9.27s

¹ Target bitrate in Kbps, as set in the UI.

² Actual bitrate in Mbps of the output video, as reported by MediaInfo.

³ Whereas 100 is the best possible score, and means - according to the metric - practically indistinguishable quality compared to the source video.
