I use mencoder to encode Flash videos for various reasons. Here's a command I use for videos of the kids:
mencoder $1 \ -ofps 30 \ -o $1.flv \ -of lavf \ -oac mp3lame \ -lameopts abr:br=64 \ -srate 22050 \ -ovc lavc \ -lavcopts vcodec=flv:keyint=50:vbitrate=600:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 \ -vf scale=480:320
That gives 30 frames/sec with a video bitrate of 600 bits/sec, and audio sample rate of 22050. For a webinar, which has fairly static screen images, I drop the frame rate to 10 or so (-ofps 10), set a bigger video size (-vf scale=720:480), and change the keyframe interval to 250:
mencoder $1 \ -ofps 10 \ -o $1.flv \ -of lavf \ -oac mp3lame \ -lameopts abr:br=64 \ -srate 22050 \ -ovc lavc \ -lavcopts vcodec=flv:keyint=250:vbitrate=600:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 \ -vf scale=720:480 \
Other possible options:
So you made some changes and want to commit to two different branches?
You have this:
$ git status modified: foo modified: bar
You want foo on branch A and bar on branch B. Easy enough:
$ git co A $ git add foo $ git commit $ git co B $ git add bar $ git commit
You want foo on branch A along with one of your changes from bar. You want the other changes in file bar on branch B.
$ git co A $ git add foo $ git add -p bar $ git commit $ git co B $ git add bar $ git commit
Note the "git add -p bar". At that point, git will ask you, interactively, which changes you want to include in the changeset.
What if branch B doesn't exist yet? Instead of simply doing 'git co B' you would do 'git co -b B'.
At some point, you have a local branch that has never been pushed to the origin (that's just the usual name for the primary remote repo, btw). You can push the branch like this:
$ git push origin B
That pushes the current branch to a branch named B on origin. You could be on branch B, and do this:
$ git push origin C
And you've just pushed to a branch named C, and confused your future self.
Suppose you want to set up the remote branch and the local branch should track it. So that git status will show you things like "Your branch is ahead of origin/B by 10 commits [ you should push]" and also so that you can, in future, simply run `git push`. Then you'd do this on the first push:
$ git push -u origin B
And subsequent pushes would just be:
$ git push
When creating a branch with git:
git co -b new_branch_name
This says make a branch named new_branch_name and switch to it.
When the time comes to push it to your remote server:
git push -u origin new_branch_name
This says push the current branch to origin (your default remote server) and call it new_branch_name on origin, and also set up to track that remote branch (-u). Tracking means, when you're on this branch and do git pull, git knows which branch to merge into this one. And git status tells you useful things like "Your branch is ahead of origin by 1 commit".
"The composability of vim commands is a beautiful thing."
Meaning that you can put vim commands together to make new commands.
