how do i get better video quality using a dazzle dvd recorder?

Q. When i record something with my film camcorder, i transfer it to my computer by playing it back and recording it onto my computer using the dazzle dvd recorder. When i do this however, the video quality drops significantly, but the audio is fine. how do i get better video quality with my dazzle, even though my camcorder doesnt have an s-video output?

A. You did not tell us which camcorder.

If it is an analog camcorder, you are reducing the quality when you transfer to the VOB DVD standard definition format. Each time you compress, you reduce quality. When you compress the video, dideo data is discarded. When you "decompress" the video, the decompression is providing only "best guess" when rebuilding the video.

If you want "best video quality", then don't re-use the tapes - transfer directly from the camcorder to the computer and skip the offload to the DVD recorder.

I don't think you are using a "film" camcorder. Film cameras would require you to send the exposed film out for developing and return to you with the developed film. Analog and digital video tape are more likely what you are using.

If you are using analog tape (VHS, VHS-C, Hi8), then get an analog/digital converter (USB for Pinnacle Dazzle; firewire for Canopus ADVC55 or ADVC110).

If you are using digital tape (Digital8 or miniDV), then install a firewire port on your computer and transfer the digital video directly. Firewire, IEEE1394 and i.LINK are all the same thing. If your computer has no firewire port and no expansion slot to add one, then your only option is the USB-connectinganalog/digital converter described above. USB-to-Firewire adapter/hub/converter/cable things do not work.

In either case, bypassing the DVD step you currently do and saving that for the LAST step of the process will greatly improve your video quality.


If you want to upload videos to the computer easily, what is the best camcorder to have?
Q. Is it better to get a DV camcorder, even though it requires a firewire port? Is it better to get a hard drive or sd card camcorder? I don't want a flash memory camcorder, but most importantly I want a camcorder with good video quality on the camera and the computer once it is transferred.

A. The best video quality continues to come from video captured in DV or HDV format. For consumer camcorders, that means miniDV tape. There are external hard drives for camcorders typically with a firewire port - from companies like Focus Enhancements (FireStore) - but even those external hard drives save to DV or HDV format.

Internal hard drive or flash memory based camcorders typically store the captured video in a very compressed MPEG2 (standard definition) or AVCHD (high definition) format.

DVD camcorders compress even more into their VOB or VRO format files and their video is not menat to be edited - though people try by ripping the video, the quality is not very good.

Video compression = discarded data = reduced video quality.

Firewire400 ports are typically cheap to add

if your computer has an available PCI port.

If you use an Apple Macintosh, they have had firewire ports for almost ten years... the only exception is the new Mac Air.

From my experience:

MiniDV tape: Lock the tape, then rewind to where you want to start the import, click import, go do something else until the import is done. The clips are a single huge file in the editor, but making the individual clips is as easy as dragging them to the desktop outside the editor window. Store the tape in a cool dry place, nice long shelf life. Camera dies, get another camera. Do not reuse tapes.

Hard drive or flash memory: Since all the files are individual (and there will be more than you expect because the largest file is 20 minutes - there is no frame drop, but there is an extra step to put the clips back together when editing), and copying to your computer is fast - some computer operating systems may need an additional file conversion step. Before you start editing, make another copy of the files for archiving... another hard drive or burning discs (data DVDs, not video DVD format). Camera dies - let's hope all the files were transferred, otherwise, the internal HDD is not removable, so get to know folks like http://drivesavers.com/ and open your wallet REALLY wide...
