I performed the transfer last night. Since the whole purpose of the excercise was to have two versions of the same event on the same tape I performed the basic tape to tape using the firewire/i-link connection. If it didn't work satisfactorily I would just record over the duff bits.
It was an easy thing to do, connect lead, press record/pause on destination and play on the source. When required scenes were being played I took the destination off pause and stopped it at the end. Not frame perfect but OK for the purpose of this excercise. With ilink allowing transport control I would have thought that it was possible to have one unit control the other but it would appear that an external edit controller would be required to perform this task.
HDV and DV seems to coexist quite happily side by side. There was a short transition period of blank during playback as HDV goes into DV which caused the TV to resynch from 1080i to 576i. Setting the output of the HDR-HC1E to 576i also had a short blank transition phase - it maybe that I left a few blank frames at the end of the HDV before recording the DV or there is indeed a transition whilst the HDR-HC1E processes the transition between HDV and DV. If it is the latter, it will be unacceptable for a smooth frame perfected edit but it is just fine for my purposes. As expected, small borders at the side catered for a 4:3 frame in a 16:9 format. Interestingly datacode time and exposure information were preserved during the transfer.
Being able to compare the results of the well respected Sony TRV900 and HDR-HC1E were quite interesting, especially when viewing like for like at 576i output via component on a 32" LCD display. Even at SD, the HDR-HC1E proved noticably the sharper picture. The scenes were shot inside a church with areas of low light and where the sun shone shined through the window bright spots of light. The HDR-HC1E showed no signs of grain whereas the TRV900 did - odd since in reviews of the HC1E it has been criticised of having grain in low light. Exposure wise, it was a close call. At first it looked as if the HC1E when playng at HD 1080i had over exposed by quite a bit whereas the TRV900 looked very good indeed. However, when we were looking at the results in SD 576i, the exposure of the HC1E appeared as good as the TRV900. This seems to indicate a fault in my system upstream of the HC1E when viewing HD content at 1080i. I tried to calibrate the over exposure out on the display but could not manage it. It looks like everything from about 70% - 100% IRE is compressed with little or no contrast. That will be something for me to fathom another day but will be difficult without an alternate 1080i source so check against.
Thanks all for your help
