Bit rate for slideshows

[Berzelius]

I've just completed a slideshow project containing a number of titles, each of which I first converted to a video file at 4000kbps. It now occurs to me to wonder whether the bit rate is important for a slideshow where, except for any transitions, nothing actually moves. In other words, could I have used an even lower bit rate for producing the video files without any effect on the quality (except for transitions)?

I would just go for the highest bit rate possible where your project fits on the DVD.

I agree with Clevo. So if your slideshows play for around an hour or less, you could burn using an 8000 kbps bitrate for highest quality. And correspondingly lower the longer your slideshows last. They may originally be made up of still images, but they have been converted to video, and the same rule applies to the frames i.e. the lower the bitrate, the lower the final quality of playback.

Thanks for the reply. Following on from earlier advice in the forum I used 4000kbps as the total length is 1 hr 48 min. I was just wondering whether it was allowable to reduce the rate even further to make the video files smaller without loss of quality. Obviously the saying that there's no such thing as a free lunch applies here!

Hi

You will probably get in excess of 120 minutes using 4000 kbps

Check the size of your 1 hr 48 minute file and compare it to 4.3 Gb
That¡¦s the size that a single layer disc will hold.
A quick calculation will tell you how many minutes you have left to fill the disc.
