    problem editing a file


      Hi: last night I  converted an F4v file to mpeg 2 and avi. They play quite well on my computer media player. When Importing it to Premiere Elements 8 , the file jumps when previewing and rendering. Like a touch of "fast motion" and jerky stop and go effect. Any help on what to do or what is wrong to fix this.

      Thanks howard

          How much system memory you have installed, such as 2Gig or ???
          Operating System version, such as Win7 64bit Pro... or whatevevr
          -including your security settings, such as are YOU the Administrator
          -and have you tried to RIGHT click the program Icon and then select
          -the Run as Administrator option (for Windows, not sure about Mac)
          Your Firewall settings and brand of anti-virus are you running
          Brand/Model graphics card, sush as ATI "xxxx" or nVidia "xxxx"
          -or the brand/model graphics chip if on the motherboard
          -and the exact driver version for the above graphics card/chip
          -and how much video memory you have on your graphics card
          Brand/Model sound card, or sound "chip" name on Motherboard

            Well, I figured out what was going on! The video frame rate was to HIGH when converting the F4v file. I changed the conversion frame rate to 25 fps and it is fine now. NEXT big question. I know when ripping dvds for editing on adobe,,it is best to use the VOB file to edit on adobe. In the ABOVE case, where I downloaded a clip (file) converted it from f4v to both avi and mpeg 2.....what is the best format to edit in elements to also eventually the best mpeg 2 for computer PICTURE?

            there are so many files you can convert the f4v to; what will give me the best results in the END?

            Thanks Howard

              Glad that you got the Frame Rate handled.


              For editing in PrE, with SD (Standard Definition) material, the ultimate format is DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio. That is the format that gives the very best results, and is the format that PrE is built around.


              Now, for ultimate quality, one should START with that format, as it is only very slightly compressed to start with. When one starts with other compressed formats, the only thing to be gained is the ease of editing, as that initial compression has already striped much data from the file to begin with. Conversion will make editing easier, but will NOT restore that lost data. It is gone forever.


              When faced with other formats, I always convert to DV-AVI Type II files, even if PrE can Import them, such as WMV.


              An exception would be if I only had an existing, 100% DVD-compliant VOB, and then I would Import those. If the VOB's were not 100% DVD-compliant, say from a DVR device, I would either directly convert to DV-AVI, or would use my DVR deck and my Canopus A-D bridge, to Capture from the DVD to DV-AVI Type II files. This is just another form of conversion.


              If you are then going to DVD, there WILL be another compression step involved, as DVD is MPEG-2, and that requires compression - again. In the case of having to use DVD to begin with, I just explain to my client, that they will have to live with the double MPEG-2 compression, and show them where this will likely show up the worst. If they cannot live with that, then there are but two choices: go to the original material, before the DVD, or scratch the Project.


              In some cases, the client started with a miniDVD camera (MPEG-2 compression # 1), then went to a DVD (MPEG-2 compression # 2), and now want to edit that to yet another DVD (MPEG-2 compression # 3). Almost all motion will show artifacts, and there is nothing that can be done about that. It will look horrible.


              If you can go to the original source material, before any compression, or any other compression, you are best off. If not, converting to DV-AVI Type II will be the next best option.


              Hope that helps, and good luck,
