I am trying to decide the recording speed to use for dubbing my Hi8 home videos to my Panasonic DMR-ES15. The Hi8 tapes are two hours each, so SP (2-hour) would be the most convenient. However, as I would like to have the highest-quality dubbing to DVD, I could also use XP (1-hour) and record to a dual-layer DVD+R. This would be a hassle, in that I would have to stop the Hi8 tape after 60 minutes, finalize the first layer on the DVD recorder, then dub the second hour onto the second DVD layer.
So what I’m asking is whether the quality difference between XP and SP on the Panasonic recorder would be significant for video that has Hi8 as its source. Since Hi8 records two hours of video onto the same length of tape as my Digital8 camcorder records only one hour, I am wondering if Hi8 uses only half the bit rate of Digital8. On the other hand, maybe the additional tape required to record one hour of video on Digital8 is because of date and timecode data, which analog recordings do not have.
In short, can anyone advise as to whether Hi8 would look just as good dubbed at SP as XP on this Panasonic recorder?
Thank you in advance for your advice.
