Quality after cature

[LeThanhNguyen]

Hi everyone,
This is an absolute Newbie. I have a problem with the clip quality after capture from Digital camcorder and look for your help. I have captured a movie from the tape to computer via USB port using Ulead VideoStudio 9.0 then burned to DVD. Problem is the quality is much lower than the clip which uses the tape on TV (it is only about 70% in comparison with the tape). I checked the clip file.AVI and recognised that it is worse than the origin (the tape) and the converted file to MPEG for burning into DVD is worst. I thought may be because of the software so I used Nero to capture and found the quality is not better. Another problem is the synchronisation between the voice and the picture in the DVD clip, they are not in the same time. A friend of mine advised me that I should use the Firewire conector IEEE 1394 to connect with computer but I am not so sure as my computer doesn't have IEEE 1394 port, if it was correct I will buy the 1394 card and cable. My computer configuration is Petium iv 2.4, RAM 512 MB;HDD 80GB DVD writer Samsung SH162.
My question is that is it correct if the connection via IEEE 1394 will improve the quality?
If not what cause the bad quality? Software or other hardware?
Thank you for your help.

Your friend was right. Get IEEE-1394 for a quality transfer.

DV camcorder USB is usually low bitrate MPeg intended only for web streaming.

Firewire cards are quite inexpensive. If you need a good editor, these cards are often bundled with excellent editing progs at a very good price.

Both USB and Firewire offer a simple file transfer. The problem is not really inherent in the connection, just that many cameras specifically limit the quality of the USB transfer in order to lessen the filesize and therefore the transfer time. The higher bandwidth available with firewire removes the need for such limitation.

See if your camera offers a true "file transfer" mode, USB would take longer but there is no good reason the same quality can't be available, it is a choice of the manufacturer.

Sony DV camcorders in particular only offer low datarate MPeg2 over USB. You can't get to the DV data over USB.

Thank you very much for your held. I successed perfectly. I followed your instruction and installed the 1394 card into my computer and captured. The result has nothing to complain. I have a question that after converting the file.AVI and burn to DVD, does the converted file exist in the HDD? I understood the *.AVI is converted to MPEG 2 and burned but I can not find the MPEG file in the HDD.
You know It takes time to convert and build a file before burning to the DVD, if the second copy is needed, it takes very little time to burn it. I wonder whether we can save the converted file and the next time the DVD can be burned much faster (I use the Ulead VideoStudio 9.3)

If I understand correctly, you want to first convert the DV-AVI file to an MPeg2 file before authoring and burning the DVD. You then want to save the MPeg2 file for other uses.

I have Video studio 8 here so hopefully version 9 still works the same way.

When you have finished editing your program,

1. Select "Share" Menu on top.
2. Select "Create Video File"
3. Select "DVD". Name the file. Save. This will be your MPeg2 file.

When that has rendered,
4. Save project file.
5. Create a new project
6. Import the MPeg2 file to the timeline.
7. Under "Share", Select "Create Disc" then DVD.
8. Then author a DVD as you did before. The MPeg2 file will remain on the HDD.

Alternatively, steps 5-6 could be done in a different authoring program (e.g. TMPGEnc DVD Author, Adobe Encore, etc.)

If all you want to do is make additional DVDs from the same master file, Then on the last page before burning the DVD, select "Create Disc Image file". The ISO file will be used to create additional copies.

Thanks edDV very much. That's exactly I want to know. I have to say that my skill has been improved a lot by learning your knowledge.
