  Mpeg HD conversion issue

  Posted by Sean David on August 16, 2010 at 3:40 pm

  I expect this has been asked before in various ways, but I haven’t found the answer via searching.

  I have been supplied several HD .mpeg files which Premiere Pro CS5 reports the following on:

  Type: MPEG Movie
  Image Size: 1440 x 1080
  Pixel Depth: 32
  Frame Rate: 25.00
  Source Audio Format: 48000 Hz – compressed – Stereo
  Project Audio Format: 48000 Hz – 32 bit floating point – Stereo
  Total Duration: 00:09:02:20
  Average Data Rate: 3.1 MB / second
  Pixel Aspect Ratio: 1.3333

  I know it came from a Sony HD camera but was only supplied the tapes and capturing it was a mission via a third-party so re-capturing is not really an option.

  I have imported them into PPro CS5 but they take forever to index (some are about an hour long) and are really, really slow to scrub, edit, etc., and the indexing process sometimes starts over when I reload the project. It is way too slow to actually edit with them.

  The specs on my machine are pretty good, I7 720, Win 7, 8GB RAM, 1GB HD5870 Card, an Asus G73JH-X3. The files are on an external drive accessed via USB2 and SD AVI DV files edit flawlessly and with no delays. I have tested the files on my laptop hard drive now and it is now perfectly fast so it would appear to be too resource intensive to use mpeg files via USB2? I can put the files on my local HDD for now, but may not be able to do so in future.

  My preferred solution is to convert the files to another format with the least loss of quality possible. My project is SD Anamorphic 16:9 going to DVD so down sampling would be fine if necessary.

  I have CS5 Media Encoder, and tried encoding to AVI SD DV but the quality wasn’t good enough, there is something like ‘compression’ artifacts that were not present in the original. How do I tell if this mpeg file is interlaced and if so is that likely to be the problem here?

  I tried SUPER to export to uncompressed AVI and 30GB later for the first file the quality seems ok but the color has shifted significantly.

  I would really appreciate some suggestion as to the workflow on this as my experiments so far have not worked.

  Thanks,

  Sean
