I just purchased a NEC 2510 and Nero 6 (18.104.22.168) last week. I am trying to back up mini dv camcorder footages and using Nero 6 and I noticed quality deterioration in the final export file. Is this what is expected from Nero and/or other encoding software? To be exact, I did the following:
- Captured video to hard disk from miniDV camcorder through firewire and store as very large AVI file.
- Used Nero Vision Express (22.214.171.124) to cut the portion of video I want and export to DV-format file. Noticed slight deterioration in quality compared to uncut file.
- Then Used Windows Movie Maker 2 to do something similar and export to DV-format file. The export was much faster than Nero Vision Express and the quality was like the original captured dv file.
- Anyway, I used Nero Vision Express to open the two exported DV files and export to DVD format (Mpeg).
- Burned the Mpeg files to CD (rather then to DVD at this point because I don’t want to waste DVD disks whilst testing the files).
- Played both files on my computer using Windows Media Player and then played them on my Philips 625 DVD player.
There is definitely a loss in quality with both files when compared to the original captured DV video. I have copied mini dv output to videotapes (normal composite video) in the past and though VHS is lower quality, the taped videos were very good. I would have expected the Mpeg videos to be better then VHS tapes. I have tried re-exported using High Quality, 2-pass encoding but the same result.
What I would like to know from those of you who have experience in this area are:
- Do you find a reduction in quality from Nero Vision Express when you use it to cut portions of a video and export in DV format?
- Do you also find a reduction in quality when you export a DV file to DVD (Mpeg-2) format?
- Is the reduction in quality from DV to Mpeg2 expected from all other software?
Thanks in advance.
