    missing video


      I am a long time user of Adobe PE, now 14 and have never seen this before.


      I shot several hours of lecture video. This camera breaks one session into multiple files and all files play perfectly on the PC using VLC. Within Adobe 14 one of the files shows up with a blank video portion, sound is ok. The sequential files before and after are fine. I have done no preprocessing, just straight from the camera as always.


      I renamed & reloaded the file, same result. I removed the adobe files and cleared the cache, same result. I ran "auto analyzer" and got the same result.


      I have used this camera for several years and processed hundreds of hours of footage. The footage before and after are perfect and VLC can tell no difference between them. I've been using this PC & video card for over a year. Some files are fine, some are not, all were created sequentially at the same time on the same camera.


      Any ideas what is wrong and how I can fix it?  Thanks.

          I certainly don't see anything in your Media Info report that would indicate there's anything unusual about this file. Especially since it apparently came from the same camcorder, using the same settings, as the other videos in the set.


          I assume, based on your graphics card, that you've got a reasonably powered computer with adequate (100+ gigs) of free space, and that you've checked it for viruses and other malware.


          These are pretty large files -- each one over 20 minutes long -- so they may put some stress on a computer.


          I assume you've opened a new project and tried using only that video file in it.


          The only other thing I can think of is that you may not have given the program time to completely conform all of the files when you first added them to your project. Usually the process of conforming files, on a fast computer, takes a few seconds. But you've got several very large files -- and that would explain why the video added to your project earlier work just fine but those added later do not.

            Thanks Steve - I did try them independently. I also erased their cfa files and reconfirmed them.


            I bought a 3.4GHz i7-2600/w 8GB with Adobe in mind a year ago. 18GB videos used to take 24 hours to render/save on a Dual Core and now they take 2 hours or less. I have over 400GB free so it's not a resource issue. The other noteworthy items is that files that are sequentially after this one are fine.


            Is there some transcoder app I can use to read and rewrite the files? Maybe unscramble the coding? They play through a video player without issue.

              Try downloading the free program Handbrake. Open one of these videos in Handbrake and select the options to output it as 1280x720 at 60 fps and constant frame rate. I'll bet you a cup of coffee the video Handbrake outputs will look identical to your original footage and will load right into Premiere Elements!

                Thanks Steve, I will.


                I tried VLC's save/convert and it had no effect. I rebooted too. Running Handbrake now.

                  Well handbrake truncated the video however a good ways in.


                  I ended up taking the audio from the origional audio and the VLC convert video to cobble something together.


                  I will shoot several hours of static video to see if the camera or the SSD recreates this weird file again.

                    The save bombed with "unknown error" so I tried to render it - which completes without error.  I tried the save again, same error.


                    I'm trying a uncompressed AVI save now as per the Adobe suggestion for this error. If that works I will just use that as the source.


                    I haven't tried the camera test - don't want to loose the virgin files...
