It works !!!
I put two 10V 470uF capacitors on the SAA7110A chip and the diagonal
lines are all gone.. (I used legs (14- & 16+) and (18- & 20+))

That is not that easy, you chan caputere only every n'th frame with the
-T/--time-lapse num option.
if you want to create a single image with that you might have to work

It sure looks like the data rate for MJPEG is much higher than
DV (DV is fixed at ~25mega

Lo all,
I'm trying to write a shell script frontend to a

I've used mjpegtools to generate an MPEG-1 video. I then turned that
video into a VideoCD. Now, the videos play fine on software players, but
they cause my hardware DVD player to hang hard (have to power-cycle it).
Does anyone have any idea what's going on? Does my hardware player just
suck? It
Forgot to mention that I used vcdimager 0.7.13, dvgrab 1.2, and a CVS
version of mjpegtools downloaded about 2 weeks to a month ago. MPEGs were
encoded with -f 1, denoisified (no options), scaled to VCD, and were done
in full quality settings, and standard VCD sizes/bitrates.

Greetings,
yuvdenoise 1.6.1.90 seems to introduce an artifact into its filtered output.
The artifact is at the top left corner of the picture, has the
appearance resembling a translucent frame, and seems to have a size of
256x256 pixels.
I have created demonstration material and testcases, and
I've been doing a lot of video encoding over the last several weeks with
mjpegtools, and it's great! One suggestion I have is that perhaps when

picture in preference to the edges, or have an option to do so. I've had
some video

That was the problem, although I've had media in this SAME BATCH that
works flawlessly. Thanks, you saved me a ton of time and a lot of
headache. I was using Sta
As a previous poster suggested - it ended up being bad media. But thanks
