Default problem of head on camcorder, help

I've sold a Sony Hi8 Camcorder (first generation of camcorder,
DCR TRV-7000E ).
The buyer tell me now that he cannot read tape that has been
recorded on others camcorders (I think 8mm) and from test tape
that professionnals use.
But it record well and read his own recorded tape. He asked
a repairer that told head are defective.

Is that possible that a camcorder that record and read very well its
own tape has defective head ?

if a camcorder cannot read tapes recorded on other camcorders is
it considered defective ?

1. if the heads record and play back properly , they aren't defective
, though they may be misalligned from normal setting.

2. many camcorders cannot replay tapes from a different camcorder
especially those recorded in LP mode.

Most likely, the heads are out of alignment, which will result in the
symptoms you've described.

Yes. If it was within the alignment specification, it wouldn't have this
problem.

Given the information that we've gleaned from the OP, ISTM that the most
likely cause is an LP recording from another camcorder.

Sony manuals state quite clearly that LP recordings from another
camcorder are likely not to replay properly.

You know, the OP said the camcorder he sold is Hi-8, but he didn't say
what kind of camcorders the problem tapes came from.

One can't expect a Hi-8 camcorder to read a digital-8 tape, for
instance. By design...

On the contrary, there's nothing to indicate that the buyer of the camcorder
was attempting to play back LP tapes. The default for Sony camcorders is
SP, not LP, and it takes a deliberate change to a menu setting to access LP.

All indications are that the camcorder heads are out of alignment, which is
a very, very common condition for older consumer camcorders.

And, as an aside, it is relatively rare for properly aligned camcorders to
fail to play back tapes recorded in other machines, EVEN if they are
recorded in LP.

Incidently, not to belabor a point, but I took a quick look at your website.
It's well-intentioned, but has a fair amount of incorrect information.
Specifically:

1. Premiere is capable of time-code based scene detection on capture.
You're wrong when you say it can only import entire clips. It also will run
on less than 512 meg of RAM.

2. Capture can be done within a video editor, but can also be done with
specialized tools, e.g. Scenealyzer Live. These are capable of optical
scene detection, as well as time-code-based scene detection, and can also
preview a tape to allow clip-specific captures.

4. AVI and mpeg are particularly poor choices for sending video over the
internet. High-compression formats, e.g. Apple's .mov Quicktime or
Microsoft's .wmv are much better.

5. "Most people have a VHS recorder, but DVD can present problems"? That
may be true in Britain, I don't know. It's certainly not true in the US,
where you can buy DVD players for as little as $25.

6. What set-top DVD players do you know that will play DVD-RAM?

7. Most miniDV camcorders do NOT provide the highest quality video.
Contemporary consumer camcorders are dismal kludges that produce grainy,
noisey video. Most Hi8 camcorders will produce higher-quality video.

6. "Movies" shot in low light are not grainy, etc. unless shot with
poor-quality consumer camcorders. My camcorder is a VX2000 miniDV and it
produces brilliant, sharp, saturated non-grainy video by the light of a
single candle. There's nothing inherent in either digital formats,
generally, or the miniDV format, specifically, that results in poor
low-light performance. The effect that you describe is the result of
deliberate design compromises introduced by camcorder manufactures in their
lower-end consumer machines.

7. "Nightshot" is simply infra-red sensitive videography. It is not
limited to 3 feet and produces wonderful results with good camcorders.

8. PAL camcorders are available from reputable dealers in the US at good
prices, e.g. B&H and Adorama, both of which are extremely ethical, reliable
and will readily accept returns and exchanges.

9. Neither Digital8 nor MiniDV support component video as part of the spec.

10. You wrote: " You should also be aware that shooting in low light (no
matter what the manufacturer claims) results in a substantial loss of
quality." That's utterly and completely wrong. Have you ever seen the
output of a decent miniDV camcorder?

11. AVI isn't "uncompressed." AVI is nothing more than a file wrapper which
can accomodate a variety of codec-encoded video formats. HuffyUV-encoded
avi is compressed, but non-lossy. DV-25, i.e. miniDV and Digital8, encoded
avi is most definitely encoded in lossy format at a ratio of about 5 to 1.

I don't have time to review everything else on your website. I appreciate
your interest in helping other amateurs, but jumping in with misleading or
simply erroneous information does more harm than good.
