 This is a reason for concern!  It _could_ be because of your playback or
display setup, though.  But you should make sure that there are no dropped
frames or bad handling of interlacing in the DV encoding step.


The A/D S-Video/DV converting was made using the Datavideo DN-300 video HDD recorder, 250GB or 19 hours of some of my first Hi8 footages. By monitoring S-video output to HDTV during recording, I could see that the playback in general (before adjusting brightnes) became darker than the Hi8 source.

I know some of footages have some TBC error and dropout due to a growing video head error. But I used a TBC with some filtering added. I could also add that due to a faulty button panel, it wasn't possible to set the camcorder in Edit mode. But I don't think there is noticeable processing of the signal during playback on this Sony Hi8 camcorder.

Else I haven't made any extensiv testing or any customizing. I firewire mounted DN300 to my fast office workstation running openSUSE 10.2 x86_64 (Dell Precision 490, Xeon 5160 3GHx, 1333Mhz FSB, 2GB RAM, NVidia Quadro FX550, 24"LCD 1900x1200). Opened DV files in Mplayer default setup, and also upscaled the window to screen.

I won't say the converted DV quality in general bad, just not as good as monitoring playback of the S-video source. On some portions I can see some grain. Maybe this is due to I had to add brightness to the video, and/or noise from the tape. I reality I think this is just what Adobe said in their DV primer: the DV bandwidth 3.6 MB/s can be a little too small for S-video plus noise from tape.
