    Off the top of anyone’s head, is H.264/MPEG-4 AVC safe for editing?




      Hi. My Samsung MX20 camcorder outputs as MP4, and I tried converting it to AVI because I thought that there would be more trimming tools for AVI. I tried probably 3 or more MP4 to AVI converters, and all AVI ouputs never played properly in Elements. I had the following 2 problems happen to me that have been addressed already in the forums:


      Premier Elemenets 7 playing clip too fast, audio normal...


      .AVI video not importing correctly. Imports as audio only.



      In addition to these 2 things, I got random stuttering with other AVI files.

      I couldn't figure out how to trim and export with VirtualDub without blowing up the size, so I gave up on that. I recently found good MP4 cutting software, such as Yamb, so I thought I was good. But after testing it out, the sync was off. I tried other splitting software, but there were problems also with the MP4 that was output.


      I’ve decided to not convert, split, or touch the original MP4s.


      Here’s my Gspot:



      I downloaded the K-lite codec pack and ffdshow, but my windows media player doesn’t play the camcorder files, which I don’t’ mind, because VLC and Quicktime do. The camcorder files play in Elements 7, but I think there’s some choppiness that is due to my slow computer.


      I was just wondering if H.264/MPEG-4 AVC is a red flag in the same way that Divx and Xvid are.

      I saw a description of a Sanyo Xacti VPC-E camcorder that outputs as AVC/H.264 also, and that product comes bundled with Elements 4. 7 should be compatible right?




      I probably shouldn’t post since the original MP4s play, but I’m just wondering if this type (H.264/MPEG-4 AVC) may be problematic later on.

          I can't find any evidence in the specs for this camcorder that is shoots in AVCHD video.


          From the specs it appears that the camcorder shoots standard-def video. Beyond that, the specs are pretty vague, so I have to take your word for it that it saves video as MP4s.


          Unfortunately, if it is not saving to the AVCHD standard, the video is not likely to be compatible with Premiere Elements and you will not be able to edit it without converting it to a more standard format, like DV-AVI. This could well explain why you are experiencing the other challenges you describe.


          The FAQs to the right of our forum describe how to convert to DV-AVIs. Super, which is free, may work -- but Quicktime Pro, which costs $29 from Apple.com, definitely will.



          Also, which project preset did you choose when  you opened your Premiere Elements project? That too could be relevant.
