  .AVI quality and workflow

  Posted by Craig Meeks on June 10, 2013 at 6:14 pm

  Hello experts. I am using Pro 11. I traditionally use uncompressed .avi only for alpha channel renders so I havent had any issues. I often render many clips in .mp4 and then put them all into a final project to render again in mp4. Recently I’ve been trying to render all clips in uncompressed .avi then render the final project in .mp4 to increase overall quality. (is that a good idea?)

  My problem with .avi is that it comes out in very poor quality, usually choppy and sometimes glitchy. I have attached my render settings. Has anyone else experienced .avi problems like this? Or have any suggestions on workflow? Thanks.

  I think it depends on what is going to be your delivery format. YouTube, for instance, seems to like Main Concept MP4 (AVC/AAC) as a delivery format. So does Vimeo. I think it’s important, overall, to use the project settings that match your footage. Here’s some bitrates and frame sizes to throw at you:
  Frame size: HD 720p (1280×720)—again, your files may be in 1080p, so use that
  Profile: Main
  Field Order: None (Progressive scan)
  Pixel aspect ratio: 1.0000
  Variable bit rate (max) 5Mbits/sec
  (average): 4Mbits/sec
  Encode mode: automatic
  Audio:
  Samble rate: 44.1Khz
  bit rate: 320,000
  Again, these are for MP4 (AVC/AAC) file for progressive internet downloads, but I get spectacular results doing all my pre-renders of the timeline in this format and doing the final render for DVD. Just make sure you render in the Best Quality. But the professionals here probably know better than me on this topic. Where’s Douglas Spotted Eagle when you need him?

  You dont need to stress your workflow by working with
  uncompressed avi. You can simply use the Quicktime png format
  as one of the options for all your alpha channel renders instead.
  And even the Quicktime Phot-jpeg format for your final renders.

  Thanks Steve. I’ve still never tried quicktime png. I’ll give it a try. And thanks for your input Rick, I think I’ll stick with mp4 for all my renders if that’s what the professionals recommend. Uncompressed avi is a bit of a headache. I prefer 720 for my renders because of the render/upload times, and because of the video usually plays smoother for the end user. However, I use alot of screenshots and they are taken on 1080, so I like to keep it consistent.
