All to frequently, I see QuickTime Files called "Sequence 01.mov" or "Untitled Sequences.mov"
You know why this is bad right? Because you have no idea what that file is.
In the same way you should stay organized in your edit, you should name your sequences and watermark your work.
Being organized means no bins named "Stuff", "Misc.", "Other", or my favorite "Other Misc Stuff."
Naming your sequences means you can look at the file name and know what the sequence is meant for (Approval? Mastering? Client h.264 delivery?)
Watermarking your video helps your client understand what you're giving them. Every version except the final should have a watermark. It protects your work and helps your client know what it's meant for.
