I've just bought my first camcorder , the Sony TRV 19 and am very pleased
with the results when I play a recording through my video and onto the tv .
The problem I'm having is that when I've downloaded the same recording onto
my laptop ( via firewire ) I can only view the clip at 360 width maximum and
if I try to view it full screen the clip becomes pixellated and looks
nowhere near as good it did on the tv . I've tried a few things to resolve
this issue so far which are

1) downloading a piece of software called 'hires' which tweeks some settings
in the registry apparently which hasn't done anything

2) Used some software called 'DVIO' which downloads the recording straight
to the hard drive in AVI type 2 format I think , the file sizes are
consistent to sizes I've read on here ie. 5mins per gig but again when
viewing them can only display them at 360 width

I've also used tmpgenc to convert it to mpg , this actually converts it to
720 width but the quality of the clip is pretty awful which seems to
indicate it decoded it from the 360 width size ( does this make any sense
? ) .

So summing up the quality of the recording is ok , judging by the quality of
the tv picture , the file is being downloaded is the correct size going by
the file size it creates so the only thing I can think of is of a software
nature . Can anybody help ?



What did you use to "capture" the clip onto the PC?
Often the capture program allows you to specify what quality and resolution you
want the captured clip to be - any subsequent editing or conversion isn't going
to improve on that.
Make sure your capture program is set to capture 720x576 DV format and you
should be OK

A friend with a recently acquired DCR-PC105e has a similar problem.
Apparently the Microsoft DV codec *decodes* type-1 DV files at 360
horizontal resolution by default. If you have the option to capture as a
type-2 DV file then this will play back at the proper size. The decoding of
type-1 DV files is controlled by a registry key value:

HKEY_CURRENT_USER\Software\Microsoft\DirectShow\DV DecProperties\PropDisplay

Set the DWORD value to 03E8 hexadecimal or 1000 decimal for display at 720
pixels.

AFAIK this only affects decoding of type-1 DV AVI files. They always seem to
be captured at full DV resolution (3.5MB/s).

Hi Juan,
I've previously downloaded a program called "hires" which does this for
you , I've checked the registry setting and it is set up correctly . Here's
some information I sent to Lol about the capture


I captured it using VideoStudio6 package that came with my pyro firewire
pcmcia card , the Sony software is pretty useless . I looked at the
properties window of the saved clip and it read

Frame rate 25
data rate 3515
compression DV encoder type 1
attributes 24 bit 720 x 576

The clip when viewed using videostudio looks blured and pixelated but
when viewed using windows media player at 100 % shows it as being 360 x
288 . When increasing the size to 200 % ( 720 x 576 ) the picture becomes
pixelated as on videostudio , nothing like as clear as is being displayed on
my tv through my video .

I've tried to play it using Quicktime but it doesn't want to know, I've
also encoded it using tmpgenc but the results are the same with an even more
pixelated file due to the compression ie. it's compressed it as if it were a
360 x 288 file although the output mpg file is size 720 x 576 . I've put a
very small video clip ( 2.7 mb , 0.76 secs ) at

http://uk.geocities.com/stiggsy_uk/sample.avi


I've had a browse through various forums and guides but there is nothing
at all related to this problem . Any other ideas ?
