What model of camcorder is your video coming from and what format and resolution is it? How did you get the video from your camcorder to your computer?
What exact Share option did you choose when you output your video?
Do you have the same synch issues if you use Share/Computer/WMV (Windows Media) using the Cable Modem output preset?
The problematic footage is actually from AVI files that I put onto the timeline, not the actual recorded footage itself.
I have to leave for work in a moment, so this is going to be a quick response. I'll go more in depth once I get back, with information on my camcorder as well, but I made a discovery. I have "Constant Gain" audio transitions in between clips, and if I remove them and share my video, the syncrnozation issue is gone. I use this audio transition probably more than 50 times in my video, so this is problematic.
I tried sharing it as a WMV file with the "Constant Gain" audio transition and it still unsynced. I also tried sharing as MPEG with 1080i and 720p, same issue. Strangely enough in the past when I've used this audio transition I've shared my videos and they've worked fine. I'll be back around 4 PM PST to give more details as needed.
Sorry. I can't help you with non-camcorder footage.
AVI files can use any of thousands of codecs, very few of which are fully supported in Premiere Elements.
If you can identify the codec, resolution and frame rate by opening the files in a program like G Spot Codec or MediaInfo might help. But if the codec is one of those that the program doesn't support well, there is just no way to predict how it will behave.
As Steve says, AVI that is not from a camera may cause problems... but, exactly what is inside the file?
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
Thank you for the replies; here's the info on the AVI files I use that are being unsyncronized by the audio transitions:
It's video game footage that came from a Nintendo emulator called FCEUX, I use the X-Vid codec because it's the only codec I have that doesn't cause stuttering during recording.
I've shared this same video before, and the audio transitions never caused the audio to become unsynced. Only since I have nearly finished it has the sharing started to cause problems. I tried changing the audio transition from "Constant Gain" to "Constant Power," but it's the same problem. I also tried deleting and putting them back in just to see if it magically fixed it, but no luck. Potentially I could simulate a smooth audio transition by laying the audio tracks over each other on two separate tracks while fading one in and fading out the other, but I use this transition so many times in my video that it would take a super long time to make that happen.
Xvid (and it's cousing Divx) are playback codecs, not meant to be edited... and, mostly they don't edit well, if at all
To edit a divx/xvid file, or convert to a format that will edit in Premiere
That's definitely good to know when I make another video; thank you John.
