Using iMac (late 2006) with OS 10.6.8 to convert VHS tapes to digital files for storage on external hard drive. Playing tapes through a Samsung DVD/VCR combo (DVD-VR357) machine with HDMI output. Want digital files to mirror tape clarity/quality as close as possible without sacrificing a mortgage payment. Should I invest in a capture device with HDMI input? Knowing the inherent limitations of VHS tapes, would an HDMI video capture device produce a higher quality digital file than using an S-video cable with Roxio Easy VHS to DVD for Mac? If the HDMI video capture device would result in better picture clarity/quality, can you folks please suggest some options. Much appreciated.
