Default 30fps video to UK PAL DVD judder problem

Hi all
I have a Sanyo Xacti camcorder which produces excellent looking video
when connected to PC or HDTV but I have a problem when creating a DVD
for UK PAL player. In any moving scene the video has a jerky effect as if
1 in every 6 frames has been removed, I'm wondering if in the transcoding
that
the frametrate has been dropped to 25fps to play on a UK system and if this
is
the case if there is any way to create a DVD which will have smooth video
motion.
I'm using Nero 8 which came with the camera to create the DVD.
Any help with this would be very much appreciated.

The honest answer is that I don't know, but....
In another thread I guided another poster in how to convert video with
an excellent free converter.
This is the download, it is freeware and it is simple to use:
http://www.softpedia.com/progScreens...hot-93342.html
The site has a screengrab and You can do a bit of googling to learn about
it.

I created a throwaway google email account to post a full guide

The first email has the full guide, though it was compiled for the other
poster and his device, it's worth giving a try with your problem.
In your case follow the guide, but import either the original footage
or the vob files from the DVD.
Then select to create either "DVD PAL" which will produce converted
VOB folders, or select from drop down to create an MPEG2 and
tweak the settings - bitrate, aspect and framerate (25fps)
It's free and it works, give it a try.

Default 30fps video to UK PAL DVD judder problem

Thanks for your reply, I have tried a number of video converters and
AVS Video Converter 6.2 was one of them. Unfortunately the output
to DVD has the same judder as with Nero 8
The fundamental problem is that the camera can only record at 30fps
and UK DVD PAL is only 25fps. It would appear to be impossible to
convert from 30fps to 25fps without removing frames and this is what leads
to
the juddery effect. I'm starting to think that to produce smooth DVD motion
for UK one has to use a camera which can record at 25fps. Such a shame
because
in every other way the Xacti HD1010 is a really great little camera. I
notice that
the Panasonic HDC-SD9 which is similarly specced and priced
has 25fps mode so would solve this problem.
Still would be very pleased to hear from anyone who could solve the
problem with the Xacti.

Did you buy the camcorder in NTSC-land? Is that why it does 30 fps rather
than 25 fps? I don't think there is a *good* way of translating 30 to 25 -
even professional broadcasters (eg American news reports from the USA) show
very noticeable judder on movement or panning - and that's with sophiticated
modern blending of frames rather than just dropping every 6th one.

Thanks very much for your follow up post. I have also come to the conclusion
you are right that the only way to make good looking UK PAL DVD's is to use
a
25fps camera. I may still keep this one as I think some newer HDTV's and
Blu Ray players
direcly accept the SDHC cards with MP4 movies on and are happy to play at
30fps when
required to do so and hence look great.
I would simply have to buy a 25fps camera (and with lower resolution too)
to create DVD's

Xacti HD1010 purchased in UK from Camerabox.
I dont think they make a special model for the UK, this is the spec on the
Sanyo UK website.

I may be wrong But are you trying to burn a HD video on to a DVD disc.

Typical: products sold in PAL-land which are really NTSC products with a bit
of post-processing to extrapolate the extra spatial resolution or
interpolate the lower temporal resolution.

A lot of digital stills cameras which can also take movies can only do so at
30 fps and not 25 fps, even though they can be switched to output to TV at
either PAL or NTSC resolution/rate.

That records in MPEG4 with H.264 codec, the frame rate will be 24fps.
Type into google:
H.264/MPEG-4 AVC
Then do a second search on:
Converting MPEG4 24fps to PAL 25fps
Also go through your camera's instructions, Or Sanyo's Europeasn site and
their support links, there may just be a setting to change recordings from
default 24fps to PAL 25fps?
Or, the cam may have come with software that may allow capture at user
defined fps, "source" (24fps), or PAL or NTSC .
Apparently Nero8 software has a "recode" option for MPEG4 at 24fps, and
supposedly is very successful at converting, but Nero8 isn't free.

Default 30fps video to UK PAL DVD judder problem

Try this, but for HD MPEG4 clips you will need a fast, stable
and healthy internet connection!
Important to note you may have to do this is in segments
as it will only convert each segment upto 150mb max file size.
Which equates to approx 10 mins of SP DVD quality

http://media-convert.com/

Scroll down the site to the "File".Browse option and insert your MPEG4
To the immediate right is options to choose "Input format", obviously
use the drop down to select "MPEG4".
Then scroll down to "Output" format and choose "DVD PAL".
Click the "OK" button
