I've downloaded an AVI movie and am converting it to DVD format through Nero Express 2. I've done this before so I know this part will be fine. For whatever reason I have to reduce the quality manually to fit on a DVD-R disc. What I need to know is what's too low for bitrates? If I select the "High Quality" setting with Nero it puts the bitrates at over 9000. I reduced the video to a little over 4000 to have it fit. Is that going to affect the quality big time??? I see people saying they are putting 2 AVI movies on 1 DVD-R so HOW low can you go before quality is noticable reduced? Alternatively, If Nero encodes an AVI video and I still have room left on the DVD-R disc will INCREASING the bitrate improve the quality or would the original bitrate be as good as it gets? Not sure if the following will help but I got this info from AVIcode regarding the above mentioned video. File: 27 KB (0.00 B), duration: 1:43:18, type: DSH, 1 audio stream(s), quality: 54 % Video: 0.00 B, 0 Kbps, 25.0 fps, 576*240 (2.21:1), XVID = XVID Mpeg-4, Supported Audio: 82 MB, 112 Kbps, 44100 Hz, 2 channels, 0x55 = Mpeg-1 audio Layer 3 (MP3), Supported
Ignore it. A 9000 kbps DVD movie is a such large movie that will need a DVD9, to be contained. If you will create a 9 GB movie from 700-1400 MB (1-2 AVIs), don't expect great results. Remember: garbage in = garbage out. Creating a 9000 kbps from even a couple of XviD AVIs (whose bitrate will be approx 1300-1500 kbps, for a 2h movie), even if Xvid compresses much better than MPEG-2, will be useless. What you shall avoid is lowering the quality, because the movie's quality can never be increased. Personally, a suggestion would be to use a better encoder than Nero, for instance CCE (very expensive but very fast) or TMPGenc (cheap , but very slow) or something other (sorry, I've no suggestions about this, because I already use CCE + VirtualDub [to change the movie's size] + DGPulldown [to change the movie's framerate] + a good audio encoder like FFMPEG GUI (to encode the AVIs MP3 sound in MP2 or AC3), that is the ones which are the best (for me).
Sounds complicated! I have tried using TMPGEnc 2.5 DVD to convert and VitualDub as well as IFOedit (can’t remember all the steps right now) but it would never play correctly on my DVD player. The sound and picture would always be “Shuttery” for lack of a better term. As if the DVD player couldn’t read the disc fast enough and it was having mini-freezes. I’ve asked a few times about correcting this but no one was able to give me a reason why it was happening. I know for certain it’s NOT the media. On recommendations from others I’ve tried 3 or 4 brands. Both DVD-R & DVD+R.
