| Issue | Reason | Fix | |-------|--------|-----| | | MP4 only supports mov_text . Using -c:s copy on an ass / srt track will drop it. | Use -c:s mov_text (or -c:s srt for MKV). | | Audio sync drift | Different framerates or variable‑frame‑rate (VFR) video. | Add -vsync 2 or -fflags +genpts . | | File size too large | Low CRF (high quality) or high audio bitrate. | Increase CRF (e.g., 24) or lower audio bitrate ( -b:a 128k ). | | Hard‑coded subtitles look blurry | Source subtitle is a bitmap (PGS) at low resolution. | Upscale with -vf "scale=1920:1080" before burning, or extract and OCR to text before re‑encoding. | | Container mismatch (e.g., trying to put mov_text subtitles into MKV) | MKV expects text subtitles in SRT/ASS, not mov_text . | For MKV, use -c:s srt or -c:s ass . |
