As a general rule, we always create an SD and HD version of a project, and here’s our workflow.
1 – Create a sequence in the format that you’ll need first. In your case it sounds like SD. If you use your HDV footage in the SD timeline, scale your clips as needed. You’ll probably find that you can scale one clip down to fit the SD frame, then save that scale as a Motion Preset and drag that onto the other clips. Finish this sequence.
2 – Create an HD sequence of the settings you’ll need. Select and copy all of the clips in the previously edited SD timeline, and paste them into the newly created HD timeline. From this point you will most likely only need to scale the clips to fit the HD frame, again use a saved Motion Preset to automate this. If you have titles, you may need to create HD versions of them rather than simply scaling the SD versions up.
