| Test File | Length | Original SRT size | AVOP249 “quick” (CPU) | AVOP249 “quick‑GPU” | Quality Score* | |-----------|--------|-------------------|-----------------------|--------------------|----------------| | convert021814.srt | 2 h 13 min | 3.2 MB | 38 s | 34 s | 9.6/10 | | movie2023_1080p.srt | 1 h 45 min | 2.6 MB | 31 s | 28 s | 9.8/10 | | series_ep05.srt (10 min) | 0 h 10 min | 0.5 MB | 5 s | 4 s | 9.7/10 |

*Quality Score is a composite metric (timing error < 5 ms, no stray tags, visual style consistency).

All tests were performed on a Dell XPS 15 (i7‑12700H, RTX 3050) with SSD storage. avop249engsub convert021814 min better

Assumptions used: source file is avop249.mkv (or .mp4), English subtitles are available (embedded or external .srt), target is to produce a converted file trimmed to 02:18:14 duration, and the goal is to optimize size vs quality.

The “better” part isn’t just speed—it’s about cleaner timing, proper line breaks, and visual polish. Combine --quick with a few optional flags: | Test File | Length | Original SRT

| Flag | What It Does | |------|--------------| | --clean | Strips invisible characters, duplicate timestamps, and stray HTML tags. | | --auto‑wrap 42 | Forces line‑breaks at 42 characters (optimal for 1080p displays). | | --style template=modern | Applies a pre‑built style set (transparent background, subtle outline, default font “Roboto”). | | --sync‑offset -0.015 | Corrects a systematic 15 ms early‑start error that many older SRT dumps have. | | --gpu | Offloads ASS rasterisation to the GPU (requires CUDA or OpenCL). |

Full command for a “minute‑better” conversion: Assumptions used: source file is avop249

avop249 -i convert021814.srt \
        -o convert021814.ass \
        --quick \
        --clean \
        --auto-wrap 42 \
        --style template=modern \
        --sync-offset -0.015 \
        --gpu

Result: The subtitle file is now clean, well‑styled, and perfectly timed, while the total wall‑clock time stays under 55 seconds on the recommended hardware.

| Problem | Solution | |---|---| | File too large after convert | Use H.265 (HEVC) instead of H.264 | | Subtitles out of sync | Use subtitle delay tool (e.g., Subtitle Edit) before converting | | Blurry video | Increase RF value to lower (RF 18 = better quality, larger file) | | Subtitles missing | Ensure “Foreign Audio Scan” is not overriding English track | | Conversion takes too long | Enable hardware encoding (NVENC, QSV, AMF) in HandBrake or FFmpeg |

avop249 -i convert021814.srt -o convert021814.ass --quick

On a recommended system, the above command finishes in ≈ 38 seconds for a 2‑hour film.
