dvd video capacity

[Roman Melekh]

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, 352×480 (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?

[Eric Pautsch]

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…

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 🙂
