除左容量細d....mpeg 4 會唔會比mpeg 1 更靚 ?

[edho]

mpeg4 靚過 mpeg1
但係冇mpeg2(dvd) 咁靚

[kkkleung]

Compression ratio of MPEG4 is larger than MPEG1 & 2. Therefore, the MPEG4 quality will be degraded a little bit.

Movie quality for same resolution:
MPEG1>MPEG2>MPEG4

File size for same resolution:
MPEG1>MPEG2>MPEG4

[edho]

Movie quality for same resolution:
MPEG1>MPEG2>MPEG4

you mean mpeg1 better than mpeg2?
but mpeg1 is vcd format
and mpeg2 dvd format?

[kkkleung]

Yes, VCD uses MPEG1 and DVD uses MPEG2.

I mean the movie quality of MPEG1 is better than MPEG2 at the same resoluttion. For instance, the quality MPEG1 file of resolution at 640 x 480 30fps is better than the quality MPEG2 file of resolution at 640 x 480 30fps.

Mpeg 1 壓縮比係比較小架

Mpeg 2 次之

Mpeg 4 則最大

因此 Mpeg 1 o係破壞性壓縮壓得最小既大前提下, 畫質是最好的

但問題是...用 Mpeg 1 要做到 Mpeg 2 o係 dvd 上面既畫質, 個 file 就會大好多喇

[taolala]

黎緊....會越來越多dc 用mpeg 4 嗎?

[edho]

thx kkkleung and dnamc2 for telling me about this.

[kkkleung]

Although, the MPEG4 file is highly compressed, I do not find the movie quality degraded by my eyes.

It is actually cannot distinguish the MPEG1, MPEG2 and MPEG4 movie quality by human eyes.

Therefore, MPEG4 is preferable for movie file. Thanks MPEG4.

有無software 可轉mpeg 1 to mpeg 4?
