avimerge no longer on Ubuntu 20 ??

I have a web site that takes a image every minute and at the end of the day I make avi of all the images. At the end of the month I make an avi of all the daily avi's and have done for years. At the end of this year I intended to make a video of all the monthly videos as well

I had to stop using mencoder as it did not always work and started using avimerge with great success for years. on find the first day of January 2021 my script failed as it could not find avimerge on my system.

I had Ubuntu 18.04 and I upgraded to 20 and now avimerge has dissapeared from my system.

I tried to install
Quote:

apt install avimerge Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package avimerge

I found that avimerge is part of transcode but that is not found

Quote:

apt install transcode transcode-utils Reading package lists... Done Building dependency tree Reading state information... Done Package transcode is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'transcode' has no installation candidate E: Unable to locate package transcode-utils

I tried apt-cache search transcode and it gave me a long list but most were library files.

I have ffmpeg installed and I thought it was part of that

I am working on a workaround with ffmpeg concat but avimerge works so well

Any help on how to install avimerge to Ubuntu 20.04 would be greatly appresiated.
