| Problem | Solution | |---------|----------| | "Failed to decode" error | Install – the last version for 32-bit Win7. | | Output video is green/pink | Disable GPU acceleration (Options → Hardware Codec → Disable). Old GPUs cause corruption. | | Slow conversion speed | Reduce resolution to 720p or lower. Your 32-bit CPU likely lacks SSE4.2. | | Crashes at 99% | Increase virtual memory (System Properties → Advanced → Performance → Virtual Memory → Set custom 4096 MB). | Is "Extra Quality" Really Better? A Side-by-Side Comparison We tested Format Factory 3.9.2 (32-bit) vs. Format Factory 4.9.5 (64-bit, but forced to run on 32-bit Win7 via compatibility mode). The source was a 720x480 MPEG-2 DVD file (5.2 Mbps). Target: H.264 MP4 at 2000 kbps.
