Re: Can this be stitched at all?

Hi all,
I am stitching frames of a video. When watching the result the seam flickers.
Bruno suggested to use --no-optimize for enblend to solve this.
But it didn't.
So I thought I save a mask once and then use it for all images.
Mask saved in hugin using --save-mask as enblend options.
However I get this error when using enblend option --load-mask with hugin:
enblend: input image "/home/me/mask-1.tif" does not have an alpha channel
Whats wrong?
Thanks,
Jan
Enblend version:
me <at> ubuntu:~$ enblend -V
enblend 4.1-60f6a8a30980
Full error message:
make: `test' is up to date.
nona -z PACKBITS -r ldr -m TIFF_m -o 1a -i 0 /tmp/huginpto_DPI1wG
nona -z PACKBITS -r ldr -m TIFF_m -o 1a -i 1 /tmp/huginpto_DPI1wG
enblend --compression 100 --load-mask /home/me/mask-1.tif -w -f836x418 -o 1a.jpg 1a0000.tif 1a0001.tif
enblend: input image "/home/me/mask-1.tif" does not have an alpha channel

Bruno,
it got a bit better, but it still flickers.
Also I am totally unsure about photometrics. I just adjusted EV a bit by try and error.
But I managed to get the quality of the source images up by extracting the frames using avidemux instead of mplayer. Then redid the whole project.
Anyone knows why this does not extract the best quality jpgs?
mplayer -vo jpeg:optimize=100:quality=100:outdir=/home/me/frames video.avi -nosound
However even with the --no-optimize parameter it still flickers at the seams.
Please find 100 left and right frames (zip), .pto, pto.mk and the resulting (longer) .avi here:

Btw. avidemux can "play" all jpgs in a folder. Just pick the first one and click "play". (In the lower left hand corner). Saves you the creation of a video for testing.
Btw, how do you stitch all left and right frames in a folder?
I probably do it wrong by using a custom shell script.
Thanks,

The seam is being placed in a different location in each frame, you
can use the enblend --no-optimize parameter to force a fixed seam
location (this will be quicker too).
