If you're serious about video, get a tripod. In most cases you should not have camera shake. They call this "locked down".
There are some inexpensive alternatives for editing software, too. I use Final Cut Pro, which isn't all that expensive but requires a MAC to use it. I adjust color, contrast, sharpening, masking and remove audio with it.
My time lapses are done mostly in Photoshop CS6 but I may pull it into FCPX to see if any other tweaks might boot the clip's appeal.
As far as keyboarding, I used to do it manually but now I have created CSV files for each agency. It's a bit of a hassle maintaining multiple CSV's but very fast when uploading them to the bulk uploaded clips. Some agencies claim they can accept other agencies' CSV file but I have found that to not be true. Search for each agency's CSV video requirement and they all have samples that you can exploit.
