Nut mouth should not occur when capturing video from DV via IEEE1394
without digital data processing. Fast HD will not help in this kind
of capture but good for video editing because video editing involve
very frequent data read/write on HD.
It usually occur in 3 situations:
1. capturing using analogue route like S-video or composite
2. Realtime hardware or software encoding during capture, especially
doing realtime audio compression together.
3. sometimes, just software encoding after video editing.  |

我做 DV AVI Edit 3-4 年
可能 HD 有 7200轉，都未試過 Nut 咀

dvd,
Thanks for your correction. DVDshrink is a freeware 
I agreed with you that editing part is also time-consuming, but that
is the most interesting part and that's what dvd-recorder cannot do,
like designing menu, adding subtitles, adding transition....
Moreover, CinemaCraft encoder is really very good and I always want
to have one but very very very expensive, seems like more than
HK$10000.
waiwai,
If your OS is WinXP/Win2k/WinMe, no driver is required for IEEE1394
capture card. All other things are done by software and the capture
card just acts like a copying machine only. That's why the card
itself is cheap if there is no other function.
Software encoder has better quality because
1. They has 2-pass encoding, ie. the film will be encoded two times
to get the best quality at a particular bitrate. With 2-pass VBR
(variable bitrate, not CBR constant bitrate) mode, the file size
prediction is much more accurate.
2. A lot of filter you can use for pre-processing, especially if you
know about avisynth. One of the most useful type of filter is for
noise removal which is quite annoying in indoor or nightime scene.
Moreover, those filter is free and constantly updated.
3. One more thing is that TMPG let you preserve the interlaced
structure of your DV movie. I don't recommend to change to
progressive structure as the final mpeg2 film is less fluent (576i
50 FIELDS/sec versus 25 frames/sec). Moreover, such change means
loss of information. I don't know if DVD-recorder will do such
change or not. But most video editing software with built-in mpeg2
encoder will change interlaced structure to progressive structure.
This is not the same as the line doubler or scaler which change 480i
(29.97 frames/sec) to 480p (29.97 frames/sec).
Too long again  |

1. I have try some NLE software that built-in MPEG encoder
like Ulead Media Studio Pro, PowerDirector, Studio DV
I find that TMPEG and Procoder is much better than all above.
2. TMPEG is a very good product from a Japanese young boy.
After I meet Procoder. I find that it is much professional
and the encoded picture is brighter.
3. Procoder 2.0 can plug to editing software like Edius and
Premiere Pro. U can direct encode from timeline.
4. Now, I think software solution is better than hardware.
a. Hardware solution is much expensive than sofeware
b. Technology is change very faster. Take HD ( mean HDV format )
for example, I think hardware solution will come much
late and more expensive than software solution.
5. Some hardware solution will limit the software like StudioDV
I cannot using other NLE or encode programs. |

dvd
- what I'm doin now is to extract the datecode
and input as subtitle file to IFOEDIT,
as I only want to view it as subtitle.
As I remember DVD Workshop 2 can do that
Try to have a look
U can download the user manual from Ulead. |

1. 你是否指ProCoder係最好用, 佢係software定hardware? 要賣幾錢?
Procoder is the best I have try.
It is a software encoder.
ProCoder 2.0 upgrade HK$1,200.00.
ProCoder 2.0 retail price HK$4,000.00
2. 同埋你哋之前所講嘅時間, 係有dv capture card定係冇呢?
I capture using general IEEE-1394 I/O card ( TI chipset)
All speed is counted for sofeware encode
( Be minded that different setting will change the quality
and encoding spped very much, i.e. 1 pass vs 2-pass
CBR vs VBR ) |

Waiwai, I have the same thinking as Oliver, but as I mentioned
earlier, only if you can afford the time, it will be fun producing
DVD the SOFTWAY. The time-consuming part is not the encoding part,
you can just on the machine and go to bed, but the time spending on
learning software, designing the menu, chapters, subtitles, music
...etc.
Anyway, regarding your question 咁可唔可以用dvd錄影機, 錄成dvd, 再?去
電腦做edit呢? If your editing is limit to cutting unwanted scene, yes
you can do it easyly with the freeware DVDSHRINK.
Oliver, Cinema Craft is so much faster than TMPGenc, it is 3X the time
for a 2 PASSES. |

One more thing, why the quality from software encode is better than
hardware encode? |
|
|
|
|
|
|
|
|
Wow! Very detail.... Thanks Oliver....
One thing I would like to clarify, is that only buy a IEEE1394 card
to insert into the computer. And then capture, edit and encode
actions are all executed by software only. Right? |
|
|

waiwai,
I want to clarify that 1hr DV video will make a 13G file, probably
peter so hing has captured his DV video to computer by composite or
S-video route and a raw avi file was produced (much much bigger than
DV-avi file).
All IEEE 1394 capture card can do the job but the price varies,
which depends on the bundled software and whether the card has
hardware MPEG 2 encoder function. So if you already got eg.
Powerdirector.. and don't like hardware MPEG 2 encoding, just buy
one less than HK$100. The quality should be the same since capturing
using IEEE1394 to DV-avi involves no processing of digital data.
Most important, there are two types of DV-avi files depends on what
capturing software to do the job; type 1 and type 2. The microsoft
movie maker and adobe premier will produce type 2 DV-avi file which
can edit by almost all software (including Virtualdub which is free
and fast but no special effect). I prefer microsoft movie maker 1.
To compare hardware and software mpeg2 encoding, I think software
will win for quality and hardware encoding will win for speed (real-
time). CinemaCraft encoder (software) is very good for quality and
speed but very very very expensive. I heard that Procoder is good
too and Canopus also produced good av editing product but expensive.
Personally I still prefer software encoding because of better
quality. I used TMPG as the quality is good and it's price is
acceptable. If your computer is not fast enough, just start the
encoding before going to bed and you will get what you want the next
morning.
For me, I will first capture DV to avi to computer, then edit,
encode and burn. Today hard-drive is getting cheaper and cheaper and
space should not an important issue. For one hour movie, around 40G
space is enough, preferrably 20G/20G in two partitions. One 20G for
capture and one 20G for editing as working platform and saving the
final mpeg 2 file. This will speed up by this simple way.
If you edit the file after MPEG 2 encoding, you got two problems:
1. you can no long cut the film at the exact frame (because avi
contain I frame only but MPEG 2 has IBP frame, you cannot cut the
video at B or p frame).
2. If you have done some transition or adding text, the modified
part of video will need to be re-encoded again, producing much
poorer quality video.
Lastly, forget about editting the video burned by DVD-recorder. It
will be much more complicated than what you expected.
Probably too long  |

買張Pro小小行 hardware o既 Capture啦!
我用2.4E+1G ram 做20分鐘片就等兩個幾鐘,仲未計入電腦同做剪接o既時間
如果張Capture咭係行hardware做實時壓縮的話,可以直接由 DV 以 MPEG 2格式
入電腦,但最好用一個獨立 HDD 存放影片 |

>>I thought it should be, capture avi, convert to MPEG2 (because the

咁可唔可以用dvd錄影機, 錄成dvd, 再攞去電腦做edit呢? |

Thanks for the info 米高, what I'm doin now is to extract the datecode

Wai2wai - 請問先後次序係唔係先capture avi, 然後edit,
跟住先convert去mpeg2, 再燒碟....?

Can you keep the date-code (time stamp) after the encoding?
- As I know, not.
But u can try to recall the timecode into picture with Sony Vegas
and encode the avi file to MPEG with any encoding software
The reason why I still prefer PC software encoding is because I'll
lose this data if connect and convert-direct thru IEEE.
- U mean u use the AV-DV function of DV camera?
if u use this function, no timecode will generate.
U need to key the date within NLE program
Can you manually set the BIT Rate? CBR and VBR?
- Nearly all encoding program can do it.
Can it produce PS or ES stream of MPEG?
- Canopus Procoder support
Source Formats

But most important one is follows:
HD and HDV Support
ProCoder 2.0 fully supports HD (720p and 1080i) and can transcode
between HD and SD seamlessly. It can also encode HD resolutions and
frame rates between formats, including MPEG, DivX, Windows Media 9
and QuickTime. ProCoder 2.0 is fully compliant with HDV MPEG
Transport streams captured from HDV cameras and decks.
Can you set the number of encoding PASSES?
- Yes, 1-pass or 2-pass |

米高 ,
Heard that the Canopus produces good AVI-MPEG product, but have not
tried it before. Few questions:-

reason why I still prefer PC software encoding is because I'll lose this
data if connect and convert-direct thru IEEE.
Can you manually set the BIT Rate? CBR and VBR?
