Minumim decent average bitrate for reencoding

[herbapou]

Hi,

I am trying to make room to fit some extras when converting a dual layer DVD to a DVD-R.

I am pretty new to this and only made 3 DVD's. On all 3, I used the following bitrates in DVD2DVDR (using CCE 2.5, 2 pass VBR): [MIN 2300 / AVG 3500 / MAX 5200] and my movies turn up just fine.

But I am scare to go lower than 3500 AVG. Could I go to 3000 AVG and still get good quality?

OTHER SUBJECT:

Subtitles: I did the 2 pulldown trick for DVDMaestro, but they end-ud out of sync from the middle of the movie to the end, finishing at about 2 secs out of sync at the end. Normal?

Thanks

Since I don't care about the video quality of the extras I use VBR 1800 3 pass on all the extras and than figure out how much space I'll have when I take out the origina l VTS and replace with the re-encoded one.

I would never sacrifice movie quality to put extras on, since they are all
junk anyhow.

However, it really depends on your movie.. if it's a high action movie, then dropping down to 3000kbps is going to be noticeable, however for most movies it won't be. Just set your max high.

I've been backing up kids movies. Been trying many different options and have found half D1 encoding with 2-Pass tmpgenc (0 min, 1500 avg and 2000 max) gives respectable results.

With the above settings I can fit two movies (i.e. Shrek and Monsters Inc) and still have a gigabyte left over to throw on some cartoons.

Please note above that I say kids movies - quality is noticably lower than the original but still as good (or better) than SVCD. Sound is as good as the original as I remux the original AC3 track. All-in-all, 4 hours of videos and the original disks stay peanut butter free

On my HDTV, I can see noticable quality loss in recompressed video even in very low motion scenes with 4Mbs bitrates encoded by CCE with the highest quality settings and multiple passes using the robshot method (encoded at about 75% of the original bitrate.) Ironically, I don't notice any problems with fast motion scenes where everything is moving too fast to really notice.
