When I do captures for DVD transfers, I usually use a SVHS VCR with a line TBC (true Time-base correction) to correct horizontal jitter and an external full-frame TBC (really just a frame sync/buffer as my unit does little jitter correction) to clean up the sync (front/back porch, color burst, etc) and output proper RS-170a to the capture card. It also provides a stable continuous sync signal to prevent frame dropping.
A popular DVD recorder with pass-through TBC is the Panasonic DMR-E10. Some of the JVC DVHS machines also have pass through TBC functionality as well. |
I'd love to have a professional one, but I could not even afford a 20$ used pro unit at a ham fest a week back(low on my priorities compared to caps for my restorations).
I always thought of a TBC as only cleaning synch issues and not the video that makes it to the screen...That site stretches the definition I've always had of a TBC.
I mostly use a Toshiba D-VR5 for elimination of flag waving/ bends at the top of the screen on my tube sets. I feed it S-video from my JVC HR-S3912U SVHS-ET deck(the Toshiba is a VCR/DVD recorder, but I don't like or use the tape section of it). I also have a Panasonic DMR-E80H that may have a TBC, but the current state of my system wiring prevents me from easily testing that.
I do have a NEC brand DS8000U mkII SVHS deck with a three setting "Digital NR" that improves video noise issues(I can't find any info about this deck online). It does get motion issues at it's highest setting, but the lower settings seem to get the job done without doing that to an objectionable or noticeable extent.
I almost never transfer video tape to digital formats...As I prefer to watch my tapes on a CRT TV with a tape deck(In fact aside from my computers, which I rarely watch video on, I only use CRTs for the video I watch). Also most of my tapes are first gen time-shifts made on decks I still own and keep working, so anything more than synch correction is not all that noticeable or important to me.
