 Posted: Fri Jan 03, 2025 2:56 pm Post subject: huffyhuv compression |
 |
|
i have a video coded huffyhuv and its 14GB for 8 minutes its too much.
| Code: |
m@localhost ~/Videos $ file tg.mkv
tg.mkv: Matroska data
|
i try to compress with devedeng with reduce bitrate but loose quality.
Is there a way to reduce the dimension with no loose quality? |

Hi Marcofras,
| Code: | m@localhost ~/Videos $ file tg.mkv
tg.mkv: Matroska data |
reports media container format only.
Try ffprobe (from ffmpeg) for full media codec(s) printout.
>Is there a way to reduce the dimension with no loose quality?
You can use ffmpeg 'crop' filter to change dimension of a video.
Cropping will result in re-encoding but input codec is lossless (huffyhuv), so re-encoding to lossless output codec (huffyhuv) should be obviously lossless. |

FFV1 is pretty good at compressing video losslessly (shuold be built in ffmpeg).
Another codec to test is Lagarith. It's lossless too.
Both should compress better than huffyuv, but require more cpu cycles.

... if I recall correctly.
