could anybody suggest a non software rememdy for VHS (VHS-c) dot crawl, or is this an intereference problem on the composite cable https://drive.google.com/file/d/0B_kjh0L1etroTWt3MHFPdEVUM2s/view?usp=sharing

ItsMeLenny: related: http://forum.videohelp.com/threads/331681-s-video-artifacts
15:00
ItsMeLenny
yeah, ive been through about every forum, i spent 300 on a tbc, it was awful i sent it back and didnt get a full refund
15:01
ItsMeLenny
and i only have composite out
15:01
ItsMeLenny
i'll beee baack

ItsMeLenny: what VCR are you using?
15:10
intracube
is it possible the original recording was SVHS-C?
15:10
intracube
a non SVHS deck may bork at the signal
15:12
intracube
and what capture device are you using?
15:13
ItsMeLenny
nah, it was a consumer camera, so VHSc, i still have the camera, that is what im using for the capture
15:13
ItsMeLenny
as i tried a number of VHS players and they were all worse than the original camera
15:13
ItsMeLenny
in colour and/or alignment
15:13
intracube
ah ok
15:14
intracube
so maybe the capture device is the problem
15:14
ItsMeLenny
i was having massive frame drops but they updated the capture card and that fixed the problem
15:14
ItsMeLenny
the capture device is a blackmagic intensity pro
15:15
ItsMeLenny
its just capturing what it recieves
15:15
ItsMeLenny
so i dont know if its electrical interference, or just vhs tape degredation
15:18
ItsMeLenny
ive been told the capture card is awful based on that it doesnt have a ADC or what not, which is allegedly part of the problem, but i was given no explanation as to why that would be a problem
15:18
intracube
ADC?
15:18
ItsMeLenny
nor a solution besides "chuck it out it's rubbish"
15:18
ItsMeLenny
which for something i spent $200 on
15:18
ItsMeLenny
analogue to digital converter
15:19
intracube
ah, not enough coffee this morning :)
15:19
intracube
I use a Pana SVHS deck-->TBC-->Thomson/GV DV box (ADVC-55)
15:20
intracube
DV isn't quite as good as uncompressed but it works well
15:20
ItsMeLenny
ah yeah
15:20
intracube
http://www.amazon.co.uk/ADVC-55-Analogue-to-DV-Converter/dp/B0013UU0PQ
15:22
intracube
but it's expensive for what it is these days...
15:22
ItsMeLenny
yeah a SVHS deck might solve the problem, but theyre usually quite expensive, and the TBC i did try degraded my footage a lot, and i dont want to spend more than that what i did on it, ive been looking at comb filter devices, which after the firmware update they did on that blackmagic card it seems to have fixed the timing issues so i dont get hundreds of frame dropouts
15:22
ItsMeLenny
yeah, i was looking at those ADVCs years and years ago and always wanted one, they even brought out one with a TBC built in, but now theyre all incredibly expensive
15:23
ItsMeLenny
grassvalley i knew them as
15:24
ItsMeLenny
from this camera magazine a friend got me in probably ~2008, i still have it :P
15:24
ItsMeLenny
the Kramer FC-10D as a comb filter looks good, and theyre only 20USD, but its hard to find one that ships to australia
15:37
intracube
ItsMeLenny: does your TV have any loop-through capability?
15:37
intracube
maybe you could feed the comp signal through it and get S-Video out or even HDMI
15:39
ItsMeLenny
nah my tv is a CRT :P
15:40
intracube
might still do comp->s-vid conversion
15:40
ItsMeLenny
i think it only has composite out from what i remember, but the signal is passed straight through
15:40
ItsMeLenny
ive tested that before
15:41
intracube
RCA/phono connectors are usually fixed either in or out IIRC
15:41
intracube
but the SCART can sometimes be switched to route the signal
15:41
intracube
often an option buried in the menu
15:41
ItsMeLenny
definitely has no scart
15:41
ItsMeLenny
:P
15:41
intracube
ah ok
15:41
ItsMeLenny
has component input though
15:41
intracube

Bertl: think he means the dots in the blue sky
16:16
se6astian
good evening
16:16
intracube
rather than horizontal tearing
16:16
intracube
evening se6astian
16:16
Bertl
there is clearly some interlacing happening, but it isn't on even/odd lines, instead it seems to be off by a few lines
16:17
Bertl
the moire effect in the sky is the result of this shift
16:20
ItsMeLennny
yeah the heronbone pattern in the sky
16:20
ItsMeLennny
i thought it was a result of luma passing to the chroma channel and vice versa
16:21
intracube
Bertl: not sure what you mean. this is with the fields separated: https://lh5.googleusercontent.com/-fI9DvzK7pd8/VSKkKIYR49I/AAAAAAAABB4/pzo_htzXTbA/w720-h576-no/ItsMeLenny_deinterlace.png
16:21
intracube
dot pattern is similar in both fields
16:22
Bertl
okay, that pattern is bad digitizing
16:25
intracube
one of the forum posts said it looked like HF chroma noise leaking into the luma channel
16:25
intracube
or not being filtered properly

yeah, chroma dot crawl :P
18:29
ItsMeLennny
which i dont know if thats electrical or any kind of interference in the cable
18:29
ItsMeLennny
or because VHS is Y+C combined anyway that its 'burnt in' to the tape
18:29
ItsMeLennny
im off to bed, thanks for the suggestions
