Videos must be re-rendered every time project is reopened

Tags: #file_structure #re-rendering #file_saving #adobe_premiere_elements_10 #school #file_preview

I have just installed Adobe Premiere in a media class on about 30 workstations, and we have run in to a problem on each of them.  I'm hoping you may be able to help me.  Thank you in advance for any advice you may be able to provide!

 

Steps to reproduce problem
  1. Create new project
  2. Get Media - IMAG0043.AVI
  3. Drag IMAG0043.AVI to timeline
  4. Started rendering the clip.  Render Details says the clip is rendered as 7b53c88e... (the window isn't wide enough to print the full name)
  5. Allow the rendering to complete.  The timeline shows a green line.
  6. Save the project
  7. Close the project
  8. Open the project
  9. The timeline shows a red line.  Playback is jerky as you'd expect from an unrendered clip.
  10. If I Hit enter, it will render it again - this time with a different (apparently randomly generated) filename.
  11. Repeat Steps 6-10 until hair falls out.
Observations:
  • The status bar at the bottom of the Window says "Loaded C:\Documents and Settings\sne\sne's Documents\Adobe\Premiere Elements\10.0\Adobe Premiere Elements Preview Files\Test2.PRV\Rendered - 7b53c88e-bfd8-448...
  • If I Manually browse to that folder, I see a file called "Rendered - 7b53c88e-bfd8-448c-8246-ed4ee5553efd.avi".  That file plays just fine.
Settings under Preferences, Scratch Disks are:
  • Captured Video: Same as Project
  • Captured Audio: Same as Project
  • Video Previews: Same as Project
  • Audio Previews: Same as Project
  • Media Cache: Custom (C:\PEScratch10)
  • Disc Encoding: Same as Project
Computer Specs:
  • Core2 Duo CPU 3GHz
  • 2GB RAM
  • ATI Radeon HD 4550 video card w/512MB memory, core clock @ 600MHz, Memory clock @ 800MHz

    Computers installed on a network have unique needs and unique challenges.


    I'd recommend you contact Adobe Tech Support. Ask for a supervisor.

    First... you are in the Premiere Elements forum, but your first line says Premiere

     

    Are you using Premiere Elements, or Premiere... and which version?

     

    >IMAG0043.AVI

     

    Unless that is some other codec hiding inside an AVI file, you should not need to render... if your project is correct

     

    What is your project, and what codec is inside that AVI file?

    Thank you for your response.  I am using Adobe Premiere Elements 10. 

     

    The AVI files in use are H.264, 29.970fps, 1920x1080, 128kbps 48KHz 2 Channel audio

     

    For project settings, I've been using the preset "Hard Disk, Flash Memory Camcorder\Full HD 1080i 30".  Currently it consists of a single <15 second video clip.

    Hmmm.. I just had a strange development.  I created a new project, started to render it, and this time PE10 asked me for the activation code for the Adobe Encoder.  I saved the project and re-opened it and the rendering appears to have stuck.  I'm not sure what made the difference, but at least I know something is working correctly.  I'll play with some settings and report back if I find a solution.

    As far as I know, those files will not work at all

     

    H.264 will NOT work inside an AVI wrapper http://forums.adobe.com/thread/854115

    Nice find!  Thank you.  I figured if the codec would play, it was working fine.  It looks like H.264 support in PE10 is buggy at best.  After 2 days of testing and looking for fixes, using your advice I moved the files to MP4 containers.

     

    When working with H.264 AVI files, they would lose their rendering about 90% of the time.  Using MP4, they seem to keep the rendering normally.  Thank you!

    With an adequately fast computer, the H.264 should edit fine.

     

    Where things get difficult is when camera mfgrs. wrap the H.264 inside of the AVI wrapper. PrE, up to version 10, will handle H.264 wrapped in the traditional MOV, or MP4 containers. It does not know to look for H.264 inside of an AVI. The same is true for PrPro, up through CS 5.5. It is my understanding that Adobe has rewritten some code, so that that brand new program CAN handle H.264 in the AVI wrapper, but I have not tried it yet.

     

    The file formats, AVI, WMV, MOV, etc., are but wrappers, though there are some "common" CODEC's found inside them. It's when camera mfgrs. use untraditional wrappers for fairly common CODEC's, that issues can occur. Why they chose to do such things is a mystery to me.

     

    Many PrPro CS 5.5, and earlier, have had good luck re-wrapping to MOV, or MP4.

     

    Good luck, and maybe Adobe will have the new code to use H.264, inside the AVI wrapper, in PrE 11?
