dvd video capacity
on Nov 27, 2006 at 2:57:30 am

Just wanting to know approximately how much video content (in time/duration) can fit onto a dvd. The example being 19hrs of video. Does compression/filesize affect the capacity or is it more time-based?

Your wisdom is welcomed,

Thanks,
Dan

bitrate based :)

total bitrate = disk_size / min / 60 * 8 * 0.96
video_butrate = total_bitrate-sounds_bitrate

if you want to place 19hrs to dvd:...
1. take dvd-9 disk
2. encode video to 0.9Mbps, 352x480 (576)
3. encode audio to 64k
4. author in scenarist/dvdlad/maestro/dvdstudio

Hi Dan

Time and Bitrate are both important factors to remember. The longer the time, the smaller the bitrate you need to fit onto a 4.7G DVD-5 or a 7.95G DVD-9.

As Frippy so elogantly replied, you would need a very low bitrate to fit this much video on a disc. So low it will look very poor.

Thanks for the word of knowledge.

To maintain good quality video, how many dvd's would be required - eg. would a 3 x dvd set be sufficient?

for 19 hours - I'd say maybe 8.

Maintaining "Quality" will depend on your source videos -- are they OLD VHS recordings, are they slow or fast moving (head-to-head interviews, or sports/action), etc...

Describe what you are working with, and we can give better estimates on what might work for you...

Regards,
George

it's basically 19hrs of lectures at a convention (something i am hanging out to film!), so i imagine very static shots (2 x camera - distant / close up), internal lighting, shot on Panasonic DVX100 (miniDV), edit on FCP, nothing out of the ordinary.

Thanks for your imput,
Dan

IMHO "3500, CBR" will be best choice. Then, you need 9 DVD-5 disks :)
