automation to convert stills to movies (NOT image sequences)
on May 5, 2011 at 10:18:45 pm

I need to convert a large number of individual images to movies. These are NOT image sequences.

For example: I need to convert an individual TIFF file into a 2 second DV quicktime movie. Then I'll receive another TIFF file, which needs to become another 2 sec QT movie. Ultimately, I'll receive batches of hundreds of such images and I need to be able to convert each TIFF image to be a separate 2 sec QT movie.

I can manually do this by importing the TIFF into AE, placing it into a 2 second comp and exporting.

Is there a way to automate this process to handle thousands of individual conversions? Or is there a better tool someone can suggest to do this efficiently?

Thanks.

I'd use an editing application for this where you can specify the length of the clip on import and then do a batch export

Exactly what are you DOING to these stills? Just a straight still to movie conversion, nothing else required? If so, follow Malcom's advice.

If there's more to it, fess up...

Hi Dave,

Malcolm's answer is brilliant, I think. I'll experiment with it today.

To answer your question, I'm cutting an animated feature and the first phase is to edit what's called a 'storyboard movie' (basically thousands of drawings provided to me as TIFF scans). I used to simply import the TIFFs directly as stills into FCP, but FCP rapidly bogs down when you get to thousands of stills in a sequence. So I had the idea to convert the stills to quicktime media before I import. For the low-res period of the project, DV seems like the way to go because I get the best system performance.

So, for Malcolm's workflow, I'll set the stills duration at 2 seconds, import a batch of stills, then export the resulting movies and poof, I should have 2 second media for each panel, which I'll re-import and be good to go... one hopes.

Tom

If you already know that FCP's going to choke on your stills, here's Plan B for doing it in After Effects:

If the file names include a number, e.g. "00738_Storyboard", you can import an image sequence. Use the Interpret Footage settings to make them 2 seconds long. If you're working at 23.976 (aka 23.98), set the comp frame rate at 23.976, and interpret the footage as 1/47.952; 47.952 is 23.976*2. When you put the footage into the comp, each frame should be 2 seconds long.

I THINK that interpret footage frame rate trick will work; never tried it.

--OR--

Make a 23.976 comp. Add each still to the comp in order, last one at the bottom, first one at the top. Select all of them, and trim them to 2-seconds long. While highlighted, use the Sequence Layers keyframe assistant:

In either case, you'll probably need to adjust the duration of the comp; that's pretty easy. Keep in mind that the maximum length of an AE comp is 2 Hours.

That would be good if the final stage was this stringout of stills, but this is only the beginning; my job really begins with editing those stills to create a reference movie for animation. So, I need each panel as a discreet piece of media. I think Malcolm's solution still comes out ahead.

But thanks for the ideas; I might find a way to put your workflow to work elsewhere.
