  1. Hi All. Just flashed with hacked firmware for Toshiba m1712. Was ripping at 4X on average on dvd9 with toshiba firmware. Now averaging close to 8x. No other changes made.

    On episodic disks (especially cartoons - futurama), is there a visible difference when compressing? I did both methods splitting and making one dvdr on a regular episodic series. I did notice on a tv series (the shield) episode disk which compressed to around 50%, there was visible blockiness even after deep analysis, although the picture is grainy to start with. Would this also show on a cartoon series disk? I just ask because it would seem that cartoon disks would show less blockiness since it seems to be more of a 'simple' video. Or just split them up with shrink? SPlitting with shrink (2 eps no compression, 2 eps still pictures) was Much faster than trying to compress/deep analysis. But it would be nice to keep it like the original, on one disk.

    What would you consider as High and Low average bitrates as in an actual number, utilizing bitrate viewer. This question is to assist in making the decision in whether to use for regular movie backups and not episode disksdvdshrink or dvd2one (according to lordsmurf).

    Thanks.

  2. yes, even cartoon series show blockiness when you're compressing at 50%.

    I just backed up the special edition cowboy bebop series. there are 26 episodes on 3 dvd's. I wanted to keep the menus and got rid of all the extras, but the quality didn't turn out as great as i wanted. I should have split each disk in two using dvdfab or something. I mean, they are still watchable but could be a lot better.

  3. bitrate really depends on the length and number of episodes you want to put on one dvd-r. When i'm converting anime avi's to mpg2, I usually put like 5-6 episodes on each disk for a 26 episode series.

    my average bitrate is usually around 3900-4800.

    Well Cowboy Bebop is very detailed and has alot of high motion scenes, plus 26 episodes for only 3 DVD-Rs is alot and it sounds like you're original DVDs were a bootleg set of Cowboy Bebop. Official R1 and R4 versions was on 6 DVDs and the R2 NTSC version was on 9 DVDs. There is no official release of Cowboy Bebop that was on only 3 DVDs. I have that 3 DVD bootleg set (pressed DVD-9s, it has english and japanese audio, english and chinese subtitles) and the video quality is very bad to begin with, it was encoded with a constant bitrate and has lots of pixelation in it so I can't imagine how it would look if compressed to DVD-R.

    On the other hand, my Family Guy backups done with DVDShrink look very good and I can't really tell a difference betwee them and the originals and they have 7 episodes each DVD.

    So my guess is that the quality of the backup will be greatly affected by the cartoon you are backing up, something with not alot of detail/low motion will probably look good while with some higher detailed/high motion cartoons you'll notice problems.

    I haven't done any back ups of Futurama but my guess is that it will look pretty good when transcoded with something like DVDShrink

  5. Family guy at slighty over 50% with Nero Recode, no worries, not visible to me.

    Complexity of animation is key, imo. Looney Tunes MIGHT also be compression-friendly, as all the razzle-dazzle (dust clouds, speed lines etc) was actually a device to cut down on the number of frames needed to produce an effect, so in fact the animation is often simpler than, say, Disney classics like Snow White.

    I will probably tets this theory out. Thank goodness for DVD-RW.

  6. thanks for the replies. that was what i was thinking also that low motion would be basically indiscernable to regular eyes for regular viewing. Curiously though, futurama does once in awhile get complex animation going with cgi. wonder how that affects compression and blockiness. Appears also that bitrate is not that much of an issue regarding toons?

    Like i said, the quality is not the greatest. If i ever do it over again, I would split each disk in two. That being said though, it's really only the high motion scenes that come out really pixelated. The other parts of the movie are decent enough to watch.
