Hello,

I was able to get this to work, but I had to write out to a jpg format instead of png. Not really a big deal on my end, but now the streaks are gone. It took a little bit to get the correct colortable with IDL, but it works now.

Thanks for all the help!

[Michael Rampe]$ ffmpeg -f image2 -i image_%2d.png -y -r 20 -sameq movie.mpg

Tried this and still had streaks, so it must be further upstream.

Would an issue with the color table associated with the image possibly cause this? It might be that I have to go back to my original code and fix something in there.

Have you tried to replicate this with the images I sent you?

Thank you!

We were mainly setting the buffer to limit the size of the movie files. Not sure if that is the proper way, but it seemed to work.

I did remove it and tried it, but I was still seeing streaks, even in the original .mov file.

I will try and get the updated version. I don’t have admin privileges on the machine I’m running this on, so I will try and get them to install the latest version. It might take a little while though.

Thanks for the suggestions!

Ah… Of course… I am creating a .mov file and then converting it to an mp4 file along with a couple other formats (mpg, ogv).

To .mov

ffmpeg -f image2 -bufsize 12000.0k -i image_%2d.png -y -r 20 -sameq movie.mov

From .mov to mpg4

ffmpeg -f mov -i movie.mov -vcodec libx264 -fpre /apps/base/share/ffmpeg/libx264-normal.ffpreset -bufsize 12000.0k -b 3000k -minrate 500 -y movie.mp4

Gladly!

Here are 2 images from a time series. This was before I used the convert -type command.

Thank you for the help!

Thank you for the suggestion!

I was able to get it to work, but only for the grayscale colorspace. The other spaces are still leaving me with streaks in the final movie and an empty color table when I read it in.

I am going to keep testing this way and see what I can get.

The movie is fine if I do not use the imagemagick convert command, but when I try to combine another image (even if it is the same image) I get streaks when I use ffmpeg. I am using:

call=’convert -composite ‘+tsi_temp+$
‘ ‘+tsi_temp+’ -geometry 150×140+580+27 ‘+tsi_temp

to convert the image. The latest I have found out is after I use the convert command, the color table from the metadata is not available.

I am guessing that I am loosing information along the way that ffmpeg uses.

Thoughts?

Thanks!

Adam
