I recently decided it was time to digitize my stock of old video tapes and began with 60 video8 tapes ,all of them 20 to 25 years old. I have initially succeeded and got good results capturing several tapes but found that some of the tapes about 1/4 have playback problems all similar , resulting in large horizontal bands filling about half a frame that give very terrible capture results. I have tried to identify the origin of the problem in a effort to solve or minimize the situation in order to get a capture with a minimum quality. I have not been able searching the internet and several forums to find a similar pattern or anything that appears identical and so far without identifying the problem I was unable to find a solution, in case there is one.
The original camera a Sony CCD-F500E is no longer in good condition , eventually it will still be able to play the tapes but the cassette compartment, is blocked ,I have tried several possible solutions to open it but gave up as I think the camera need service .
As I had a Sony deck SLV-T2000 HI8 / VHS dual in good condition that reads video8 tapes I tried to use it to make the captures and tried 2 hardware approaches :
SLV-T2000 (Svideo) – canopus advc55 – pc (firewire)
SLV-T2000 (Svideo) – pinnacle moviebox usb710 – pc (usb )
The results were of similar quality and with very few or none drop frames
As a capture software I have tried windv, scenanalyser Live, virtualdub
and pinnacle studio 15 the results where all very similar but in the end I have retained as more practical the svideo-advc55-firewire and windv as capture software.
However I have not been completely satisfied with the capture results and after reading that eventually better results were possible with a dgital8 camera, bought a used sony DCR- TRV238E with TBC/DNR backward compatible with video8.
The captures with the Sony digital8 with TBC on and DNR off seemed to me to give the best results so far.
Is with that final configuration Sony digital8 (TBC-on/DNR-off) directly through firewire and with WinDV as capture software that I got about 40 very reasonable quality captured files and about 15- 20 crappy ones all with the same problem 3-4 large horizontal bands/stripes occupying almost half or even more of each frame.
I tried almost all the possibilities I could figure out to try to solve or minimize the situation:
I tried the SLV-T2000 deck and DCR- TRV238E camera using all the possible outputs, S-Video composite for the deck , firewire, s-video e composite for the camera . I tried also an external tbc the AVT-8710 in both systems and both outputs (s-video ,composite ) without any results
I cleaned the video heads from camera and deck , no results whatever
I tried switching camera TBC and DNR but again no results
Tried to record from camera to a HDD/DVD recorder LG RH199HS directly through firewire or through s-video or composite with or without the external TBC AVT-8710 without any results.
I tried to make some post processing with videocleaner / virtualdub
with different type of filters namely desinterlace, denoising ( including neat video) and several other with no better results
The tapes were ok 10-15 years ago the last time that I saw them and they don’t appear to have any physical damages. Bad and good ones are of the same brands Sony and TDK , from 60 or 90 min all of them recorded in SP . The tapes have been stored all together in a file box for the last 15 years or so and I don’t believe they have been submitted to magnetic fields during the storage..
In this moment I am out of options and I hope expert help and identify the problem and propose any action on the capture or post processing (restoration) side that can at least minimize the situation
Thanks in advance
