Which video programme is suggested to play D7000 HD movie? I downloaded a programme to play it but the quality is not acceptable. Please advise.

除左player仲要睇你部pc既config, 唔一定係個player問題.

I'll check it. But, which player do you use?

[tmchan71]

I suggest VLC player. It is free.

I've downloaded the VLC player but the problem can not be solved. :(
The video is not smooth.

Which part of PC's config is required to be changed? (e.g. Temp. memory, display config...)

=================================
All of those.
唔知你部機有幾耐, 如果兩三年內既可能都冇問題. 最好dual core, vga卡可以support硬解.
另外你個file如果係save嚮ext hdd又或者係nas既話話, 咁就好大機會會睇得唔順, 因為i/o or network速度唔夠, 可以試下save嚮pc睇下得唔得.

Nikon D7000 HD Video File size
5.5 MB/sec (1080P),
5.5 MB/sec (720P),
2.8 MB/sec (VGA)

1. 請問 5.5 MB/sec 1080P & 720P bit rate 會唔好低呀 ?
2. 1080P 同 720P bit rate 一樣, 咁即係1080P 畫質唔會好得去邊啦 ? 對嗎 ?
3. 720P 畫質好嗎 ? 能接受嗎 ?
4. 請問 720P 1G 能錄多少分鐘 ?

我用 Sanyo HD2000 HD bit rate 如下
[Full-HR]: 1920 x 1080 (60 fps, 24 Mbps),
[Full-HD]: 1920 x 1080 (60 fields/ sec., 16 Mbps),
[Full-SHQ]: 1920 x 1080 (30 fps,12 Mbps),
[HD-SHQ]: 1280 x 720 (30 fps, 9 Mbps),
[TV-SHQ]: 640 x 480 (30 fps, 3 Mbps)

請大家分享你們的心得, 謝謝 !!

Max file size per clip 4GB

Running time (approx. based on 4GB file)
12 min for 1080P, 12 min for 720p, 24 min for VGA

都係咁上下,

請問 Nikon D7000 說明書在那裡能找到有關資料 ? 謝謝 !!

24Mbps=3MBps
16Mbps=2MBps
12Mbps=1.5MBps
9Mbps=1.125MBps
3Mbps=375KBps

8b=1B

[eedbt]

5.5 MB = 44Mbps

1080p / 720p 44Mbps

File size 超大, 會頂唔順 @@"

[eedbt]

1080p / 720p 44Mbps

SDHC Class 6/10 寫入速度都無咁快,

如果真的是這速度,

就會連 SanDisk Extreme® III 30MB/s 卡都頂唔順 @@"

[eedbt]

SanDisk Extreme® III 30MB/s

30MB/s x 8 = 240Mbps 才對嗎 ?

SanDisk Extreme® III 30MB/s

30MB/s x 8 = 240Mbps 才對嗎 ?

=============================================

PC既計算方法係:
8bit(b)=1Byte(B)
1024Byte=1KB
1024KB=1MB
1024MB=1GB

所以如果係5.5MB/s, 咁理論上要class 6既卡先夠快, 但class 6既意思係(理論上可以有6 MB/s read or/and write), 但實際上因為有其他因數, 好多時都做唔到.
所以用class 10既卡會比較好.
usb II理論速度有400mbps(around 50MB/s), 但好似從來都冇一隻usb dvice可以去到呢個速度, 原因亦都係一樣.
一般usb 既ext hdd有十幾MB/s其實已經唔錯.
至於nas, 好多都用緊Gb lan, 理論上可以去到大約100MB/s, 但今期e-zone做既2-bays平價nas測試, 最快果隻都係得5xMB/s. (仲要係剛開始用, NAS會因為你SAVE既FILES愈來愈多而愈來愈慢)

5.5 MB/sec

1 分鐘 : 5.5 x 60 = 330MB
12 分鐘 : 330 x 12 = 3.96GB

4GB 可錄 12 分鐘, 太大食, 頂佢唔順 @@"
