    Working with various video codecs and formats

    Scrublitzer Level 1

      Hello,

       

      I have a general question regarding the concept of Adobe Premiere CS6:

       

      I'd like to start a project in which I can combine various video codecs and formats. I start using sequence presets where I choose a preset which matches my desired resolution, framerate and field dominance.

       

      My question now is: Does it matter at all which codec I choose?

       

      For example, if I choose AVC-Intra or XDCAM-EX: in both cases, the video preview (which is the format in which Premiere renders the timeline preview files, right?) is "I-Frame only MPEG". Is it correct, that at the end, when exporting my sequence, these video preview files are ignored anyway and everything will be rendered from the original files?

       

      If i understand Premiere Pro correctly, this is a totally different approach to Final Cut 7, where I can reuse the rendered timeline files using the "Export Quicktime" function.

       

      Please correct me if my basic understanding of Premiere Pro is wrong.

      Thank you very much!

       

      Best regards

      Mark

          Rather sequence preset, not a codec. It helps PrPro work faster. See this help section and that discussion.

          Correct, unless you ticked 'Use Previews' in the Export Settings dialog box.

          See above. The question is not whether you can, the question is whether you actually want. Reusing MPEG-2 preview files is not wise. However, if you set your preview codec to a lossless production one (which, in turn, will take more time on rendering preview files), you may want to reuse those files on exporting. Especially on conditions they won't be re-encoded. See this help section on smart rendering (can't wait for the detailed explanation about smart rendering improvements in CS Next).
