I'm on a rather long and winding road toward backing up my family's vhs tapes. I have a Toshiba vcr but wanted something better for the job, so I decided to purchace a Samsung GVR-S960 on ebay. The problem is I'm not really happy with the output.
It seems to have constant red green and blue colouration travelling across the picture. The Toshiba seems to suffer too but it's more pronounced on the Sanyo.
with a better player (s-vhs jvc/pana) you should get much less chroma noise
with the vdub filter camcorder color denoise you can remove some of it without bad side effects, have a look here: http://acobw.narod.ru/
Please attach all sample images and clips to the forum.
What you see is "chroma noise", and it looks to be caused by lack of flying erase head on a reused tape. Most of this can actually be removed in software, but it's better to remove it in hardware. See attached sample. Hardware removal is far more accurate, and can often remove 100% of the issue. Software is maybe 90% accurate at best.
You need a better VCR. Not only does this clip have chroma problems, but timing/timebase issues. Straight lines are wiggly, but should not be, and would not be in a better JVC/Panasonic S-VHS VCR.
Looks like I'll give up on this machine then and return it, bit of a shame as it's great build quality and has some nifty features but it looks like this particular one has had its day.
For the next one I'll have to choose something a little more conventional
Yeah, it seemed where there was chroma noise on the tape it was definitely more pronounced on the Sanyo. I wouldn't mind getting hold of a less abused model to check out the quality.
Incidentally it seemed to have a full-frame TBC which also worked on pass-through. Perhaps the lack of a line TBC goes some way to explain the issues you mentioned.
I capture almost always directly in uncompressed.
Then is filtered.
Then in mpeg2 or in MP4
Depending on customer requirements.
Most I just need to capture, anything to make the customer himself.
For I have for capturing the best recorder.
------------------------------
Youtube has since re-encoded.
Something unfortunate quality
... Video = 450 x 360 with 939 kbps
Watch again = OK ... but save so = No
---------------------- addendum
have just loaded the 480P version.
Looks better even if the data rate is low.

Lagarith vs. Huffyuv is preference, and largely based on codec use. For example, I can't easily instal Lagarith on Linux or Mac, which I do use at times. Huffyuv is also easier on the CPU, which can matter for single-core systems.
Thanks guys. Clearly I've got a lot to learn, which I hope to do once I'm over my hardware fixation
I use both Macbook and PC, and Macbook's Bootcamp as there's only Windows drivers for the XCapture-1. The Macbook was the better choice for capturing over my aging PC but I recently got a Xeon cpu that's compatible with my motherboard so the PC's now likely better for multi-threading.
I much prefer Windows thanks to years of experience but got the Macbook to wean myself off the PC and learn something new
