  Suggestions for high-speed draft exports

  Posted by Paddy Uglow on February 3, 2014 at 10:53 am

  Hi,
  I’m often asked to send people a draft of edits, and I need them to be
  1. Reasonably small
  2. Fairly representative of the final piece (so leaving any video effects on)
  3. Quick-exporting so I’m not waiting ages between iterations

  I’m on CS6, using Media Encoder.
  I’m probably going to be using h.264 whatever I do.
  The obvious things are to turn off “maximum render quality” and “frame blending”.
  And 1 pass is quicker than 2 pass, I assume.
  But does a high data rate mean the computer has to do less compression and exports quicker? Or is it SLOWER because it’s trying to get maximum quality?
  Would putting in a lower frame rate export quicker because there are less delta-frames(?) to produce? Jerky playback would be OK for a draft. Maybe 5fps for a 25fps video?

  Any suggestions/experience would be appreciated!

  A higher data rate will take longer to compress and longer to upload finished file.
  With the frame rate, I wouldn’t drop below half the frame rate.

  As promised, here are my test results for high-speed drafting (particularly if you need to send a new draft every time you make an update; even savings of a few minutes can mean you get a lot more work done in the day).

  It appears (in Adobe Media Coder at least) that FRAME RATE is the best way of speeding up an export.
  I turned off frame blending and maximum quality to start with.
  A 25fps export of my 6 minute 2-camera edit with some overlaid stills took 6:17
  A 12.5fps export of the same thing took 3:56
  And a 10fps (a bit jerky, but still useful as a draft) took 3:25.

  Interestingly, data rate didn’t make a lot of difference. The exports above were 640×360 at 0.3mb/s. Exports at 3mb/s were about 3% slower.

  When I did the 0.3mb/s 10fps one at 320×180 pixels, it took 3:11 to export.

  Bear in mind that the “reading XMP” stage took around 1:15 of the export time in all cases.

  Yes, this isn’t super-scientific, I’m certain that low-framerate drafts of long videos will be a lot quicker than native framerate ones. I’m not so sure about video with lots of effects etc; possibly a smaller framesize will benefit there?

  I hope that’s helpful to someone out there!
