Changing Bitrate in DVD Author

[c_hernandez32]

I use TMPEGenc DVD Author to create simple DVDs of my photoslide shows. I encode the video with Mainconcept encoder from Adobe Premiere at the highest bitrate 9kbps. This is the encoder that can be purchased seperate for use soley in Premiere Pro. A computer lab at my school has both installed in a certain lab. I save the video onto a Jaz disc and do the DVD at home. I noticed that I would fill up the DVD and then only about half of the DVD would be filled up after creating the Video_TS folder. I noticed that it would take long to create the folders. A ten minute video would take 20 to create. Is this because my computer is really slow or is DVD author converting the 9kbps video to 7.5 (which is in the general settings for each track). I use DD audio, so there is no further compression. Can I change the set bitrate or is 9kps beyond the DVD spec. I really didn't care if I couldn't fit as much video on to a DVD, but it burned me to see that the size changed after I created the folders.

If you push the bitrate higher than the spec you will most likely have playback issues on standalone players.

If it is only taking 20 minutes, I would say it is unlikely to be re-encoding. What is probably happening is that your original file has LPCM audio, which TDA is reencoding to mpeg1-layer2 audio, reducing the space required/used substantially.
