I inserted several short video clips (extention .avi) throughout a presentation of mostly still images, and the the videos are not playing smoothly. They are jerky, and some are frozen - not moving at all. What would cause this?
Please read here and answer the questions:
And for introductory video tutorials on Premiere Pro:
OK -- I am using CS4 4.2.1, on computer w/ MS Windows XP 2002, (My computer won't handle CS5 version.) The videos have extension .avi, from various digital cameras. The jerky/freezing issue is displaying during edit mode on PremierePro, as well as after I burned it onto a Blueray disc. I had hoped it was just because of my computer deficencies, and that after export to media and thru the encoding process, it wd turn out OK, but it did not.
Thx for your help Jeff, I will get better at this, and will watch the tutorial that you recommended.
>avi, from various digital cameras
That will MOST LIKELY mean they are not "true" DV AVI, but are some other codec inside a DVD wrapper

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037
Report back with the codec details of your file, use the programs below... a screen shot works well to SHOW people what you are doing
If you have a red line over the timeline after importing a video and before adding any effects... your project is wrong for your video... read above about codecs
Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project

Thank you John, this is extremely helpful. I read Bill Hunt's post, and that described the problem exactly. I used the Gspot program, and here are the Codec details on one of my problem video files:

So, according to Mr Hunt, it wd appear that I need to convert this video file into Spearmint gum? What is the program to do that??
I neglected to include the info in the last bottom box on the GSpot window -- it is headed by: Proposed Codec Solutions and Tests:
I clicked all the buttons, and it ends up with "Render OK. The Following combination of filters was used: and then a bunch of code.
I clicked the LAST blue button, and voila -- there was my video playing perfectly. I'm just not clear on how I apply that "combination of filters"
to my video to make the conversion.

Your file is MJPEG... which you MAY be able to edit without conversion

If they still will not edit, you MAY need to convert...

I am happy to report back that finally, after many hours of reading the various posts and reveiewing various software that all of you suggested, I found one quite simple solution, in the body of this post by Steve Grisetti: http://forums.adobe.com/thread/415317. Even as a novice, I was able to quite simply convert my problem video files (from older model digital cameras, canon and samsung) by using Windows Moviemaker, of all things. It worked like a charm, converted the files to DV-AVI in a matter of seconds, and they now play beautiffully in Premiere Pro. I also got quite an education on codecs in the process. Thank you everyone.
With MJPEG, I first suggest that one search the utility disc, that comes with their camera. There is usually a specific version of the particular MJPEG CODEC somewhere on that disc. Each camera mfgr. seems to love to tweak the MJPEG CODEC, to suit their purposes, and that often means that other MJPEG CODEC's might not work, or work well. The camera's utility disc should have that version of the MJPEG CODEC, but it might not be easy to find. It is sometimes a separate install, and sometimes will install with CODEC along with the camera's driver. However, in many cases, it will install, when one installs the camera's cataloging, or editing software. Even if one will not be using that software, having the proper version of the MJPEG CODEC will usually allow Premiere to edit the footage, without having to convert.
Still, converting is always a workaround, and if it works, that is great. I always like to "go native," if at all possible, but sometimes, it is just not possible, such as with Xvid/DivX, etc.
Thank you Hunt. I will definitely try that route first, if I encounter the issue again, and it is one of my own cameras. This time, unfortunately, I was putting together a retrospective on someone's life, and utilizing footage from various (unknown) sources where the stills/video clips had been taken sometimes many years ago by people I don't know.
