    codec problem with PrE 2.0

    AndrewSixtyTwo

      I needed to edit some HDV footage but only having an old laptop running PrE2.0, I converted the clips first. I converted using QuickMediaConverter to AVI/DivX was then able to view, edit, render etc. the clips in PrE 2.0. I happily edited for several weeks then, without warning, PrE 2.0 started having problems with the same clips.

       

      Now, when I open the same project that used to work fine in PrE 2.0, the clips now appear as black boxes and the video cannot be viewed. The audio can still be heard.

       

      I am guessing something was updated on the laptop and messed up the codecs. There was no restore point set so I have been trying to step back and reinstall codecs etc. Now I am stuck!

       

      When I check the converted files with GSpot it says the correct codec is installed - DivX 4 (OpenDivX).

       

      I would really like to fix the problem as I have already done a lot of editing. Otherwise I guess start again and upgrade to PrE 3 or 4 (I have tried trial versions of PrE 7&9 but they are both unstable on my little machine).

       

      Does anyone have any ideas what I can do?

       

      Thank you!

          It looks as though you took editable video and converted it to an uneditable format!

           

          Although version 2 of Premiere Elements can't even edit HDV. In fact, it can pretty much edit DV-AVIs and that's about it. (You definitely can't edit Divx in any version of the product -- or most video editors for that matter.)

           

          I'd recommend either converting your video to DV-AVIs (using a product like Super) or, better, getting your hands on version 4 or later of Premiere Elements.

            Thanks for your prompt response Steve, much appreciated.

             

            Yes, looks like I somehow managed to fool PrE with my dodgy converted files for a while, but then it woke up!

             

            I tried Super without success but saw on you'd also suggested Movie Maker as a DV-AVI converter elsewhere, which I found has worked. So I could go back and re-convert the files again.

             

            However I think I am going to follow your advice and upgrade to PrE 4.0. I have looked at the specs for it and I think my Lenovo T60 should be OK?

             

            Thanks again

              Andrew,

               

              What ever you do, I would stay far away from DivX, or Xvid. Those are very highly-compressed, delivery formats/CODEC's for deliver only.

               

              That you got Imports with both Audio & Video is amazing. Most users, with much more recent versions of PrE, have major issues, plus the compression is extremely heavy, so quality will definitely suffer.

               

              Good luck,

                As for that laptop -- it's near the bottom of the real world specs for video editing, but it may work.

                 

                It's hard to say, since the specs for that computer say it could have a 120 gig hard drive -- or it could have a 40 gig.

                 

                You'll definitely want to keep at least 20-30 gigs of free, defragmented hard drive space on your computer at all time. I don't know that that leaves you much room for your video! So it may also be wise to get an external hard drive and use it to store your video and storage files. If you keep it connected to your laptop, it may work like a second hard drive.

                 

                Although, in all honesty, you may be better off investing in a new desktop computer. This model of laptop is several years old and has a very low-powered processor. You may be amazed at how much more power (and a much more satisfying video editing experience) you can get for a few hundred dollars in a new HP!

                  - you need AT LEAST 2 drives for video editing, 3 is better

                  Trying to use only ONE Hard Drive for Video Editing
                  .
                  You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to various parts of the hard drive to do Windows housekeeping or to load program segments for various functions
                  .
                  Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work
                  .
                  You as a person cannot do both at the same time with the same hand
                  .
                  A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for easy video editing
                  .
                  One hard drive is not as good as two which is not as good as three

                    Usually, the biggest limitation of a laptop is the I/O sub-system, i.e. the number and size of HDD's (Hard Disk Drives). This ARTICLE will give you more detail and background.

                     

                    Also, many laptops have embedded Intel graphics chips. These are fine for word processing, a little Excel work, but not good for video editing. The biggest drawback is the total lack of driver updates and support. An NLE (Non Linear Editor), like PrE, interfaces more closely with the video driver (and audio driver too), than almost any other program will. It is necessary to be able to update the driver frequently, and have updates available, with video editing. If you have an Intel embedded graphics chip, you will very likely encounter display issues at some time. An nVidia, or ATI chip is highly recommended.

                     

                    Good luck,

                      Thank you all so much - this forum has to be one of the most helpful I have ever used.

                       

                      I certainly will, when my meagre budget allows, upgrade my machine - well overdue!

                       

                      In the meantime I do have three external HDDs that I can allocate as per the articles to help spread the I/O load. At least my machine does have the ATI Mobility Radeon X1300 display chipset.

                       

                      I am also upgrading to PrE4.0 to keep me going just a little bit longer.

                       

                      Thanks again

                        Having an ATI chip, and their driver support, is a very, very positive note.

                         

                        For full utilization of externals, I use FW-800's, and eSATA is even better. FW-400/IEEE-1394a will work, but is slow. Unfortunately, the USB units connect so slowly, that editing to/from can cause major issues.

                         

                        Good luck,

                        PS - We're in London in April and October, and are often told that we bring the best weather of the year. Now, there have been a few times, when we did not hear that, but fully understood. Then, there was the year that our April trip got moved to June, and it was the hottest June that either the UK, or Europe had experienced in over 50 years. Even being from Arizona, USA, the land of the desert and the saguaro cactus, we admitted that it WAS hot. Sunny London is good. Just had two guests from London here for an event, and they both commented on how nice it was to warm up - but that was just over a week ago.
