HD Capturing / DVD creation question.

gchan · Post by **gchan** » Thu Aug 02, 2007 8:37 pm

I use Canon xh-a1 camcorder for recording.

While capturing to my PC, I use my project and capture setting as

1440 x 1080
16:9
18000 Variable rate
and while making DVD it becomes 720x 580, 16:9 and 8000 bits

My friends says, capturing / editing / making dvd on 720x 580, 16:9 and 8000 bits is faster and gives the same result.

Is it true ?

Thanks

Depends on how big your TV monitor is

Tv is 65" Mitsubishi HDTV.

will it make any difference ?

It most certainly will

If you watch a video on a 12" screen you will not normally notice any difference - everything will be sharp and in focus. Play the video on your 65" screen and every spot or blemish will be magnified to the point of distraction.

One of my sons has a TV screen about the size you mentioned. Some of the satellite/cable channels - those with the TV station logo in the corner of the screen - are a good example. On a 'normal' TV set everything appears very 'normal'. On His Giant TV screen many of those TV station logo's are blurred, fuzzy and very distracting.

This is one example where using HDTV comes into its own.
With a HDTV broadcast the logo will be as sharp as if you were watching on a normal TV.

So the answer to your friends point about

capturing / editing / making dvd on 720x 580, 16:9 and 8000 bits is faster and gives the same result.

rather depends upon what you are going to use to watch the completed project upon.

Oh Thanks a lot.

Just to get my point clear

Capturing in high resolution, editing in high resolution and burning it on DVD with (720 x 580) will be of better quality when compared to capturing in 720 and burning in 720. (when watching on big TV)

This depends on how well the software can perform the HDV to SD conversion.
If you have a downconvert feature in your camcorder which when activated, on most HDV cams the HDV recorded video on the tape is output via the firewire port as standard defintion. These downconvert features in the camcorder usually do a pretty good job and is faster then having the software performing a downconvert. But it really depends on the software how well the conversion will be.
If you in PAL format it's 720x576 for dvd and I would use a pretty high bit rate with mpeg or dolby audio, at least 8000kbs.

If your NTSC I think you will find you setting will be 720 x 480
