    Working an AVI file

    kdoc2 Level 1

      Needless to say I'm new, and unclear on how to adjust settings so that I can capture and play new files. Up to now, my files have played fine in APP. Today I borrowed a friends EP-2 Camera which captures 720 AVI files on an SD card. I copied and pasted these files from the card onto my hard drive. They have the following characteristics: 30 fps; 1280x72 (1.0); 44100 16 bit (the audio works fine). They play fine in Bridge and Windows Media Player, but the video doesn't play in APP--that is, the video does not move after the first frame, but audio is OK.  I tried AVC I 100 720, seeing that it uses a "1.0", and tried some other settings, but the video doesn't play in APP. In Bridge the aspect ratio is 1.77 (that is, the width is 1.77 times the height. Suggestions?

       

      Thank you

          AVI is but a "wrapper." I do not know that camera, but what CODEC does it use? The behavior sounds like Xvid, or DivX, though other CODEC's can cause the same issues. This ARTICLE will give you some background on "wrappers," and how to peer inside of them.

           

          Good luck,

            As before, many thanks Hunt. I'll try that when I have some time.Tell me, does Final Cut have these quirks--are files, and formats, etc problems with all of video editing?

             

            I do have to hand it to you and you folks: the knowledge and service on this forum is amazing.

              Some editing software works better than others when you are trying to use an OUTPUT format for an INPUT file

               

              Some reading...

                Unfortunately, I know nothing of FCP. Still, whatever file format it is designed around, one will still get quirks with other formats. I just do not know the structure of FCP.

                 

                Sorry, but good luck,

                  Thanks Hunt: I'm not trying to be a pest about this question of one approach to video editing vs. another. I'm just beginning in this field, and trying to understand the differences. While it seems strange to me that a powerful program like APP should have trouble opening an AVI file, when Bridge and Windows Media Player can do so, that probably simply reflects my ignorance of the complexity of video editing, and of the multiple formats and codecs out there. I'll get there, with all of your help!! I'll try and read those various posts suggested.

                    You need to go back and click the links Hunt and I have provided, and READ

                     

                    I could go to MSWORD and save a file as MYFILE.AVI - but that does not mean PPro could edit the file

                     

                    AVI means almost nothing... you need to determine the CODEC inside that file

                     

                    If the codec is anything other than DV AVI type 2 with 16bit 48khz sound... you will most likely have problems

                     

                    Now... click links and read

                      Kdoc2,

                       

                      There is a vast difference between playing an AV file, and editing that same file. All depends on the CODEC inside the "wrapper." Some CODEC's are only for playback, or encoding, while some others allow an NLE to ingest and edit that material. Two examples of the former are the Xvid & DivX CODEC's. Those are "delivery-only" CODEC's. There are a few consumer-level NLE's that WILL edit those (though the quality has already been heavily compromised). An example of the latter is the MS DV CODEC, which will allow playback, encoding and also editing in PrPRo. Unfortunately, the use of each CODEC depends heavily on the particular CODEC - there are no real constants, unfortunately.

                       

                      Good luck,
