Welcome to the forum!
Likely the installation of all that "stuff" (ffdshow, DivX, etc.) has made it difficult, if not impossible, for Premiere to sort out what's what with your video. Another possible source of trouble is if you're using the trial version.
FFDShow has been known to cause problems for several Adobe programs. How was it added to the computer, K-Lite,or similar?
The MainConcept H.264 should have priority here. If there was a CODEC "pack" used, it could well be that the priority would have been altered, and something else has priority now.
I have bought a Samsung HMX-H100NM for my son, and we have had the hardest time importing the video cilps in Adobe Premiere Pro.
Here is what I found so far:
- If you check the video size on the "green square clips", it's completely bogus. It might be set to 4x13 instead of 1920x1080 for example.
- There was a firmware update for the HMX-100N on the Samsung web site in late December 2009. As of January 17, 2010, it is not there aymore. I was told at the end of December 2009 that there would be a new firmware upgrade in January 2010, so maybe a new version is coming soon.
- After upgrading the firmware (I'm not sure exactly what happened with the old firmware installed, except that importing didn't work at all), I find that I'm able to import some clips if I set the camera resolution to "fine" or "superfine". The other resolution still gives me clips that I cannot import. When a clip import is successful, I can play the vide. However, if I save the project and reopen it, I will get "green squares" in lieu of some of the good clips. Rebooting the computer and reopening the same project might give me a different set of bad clips. I have reported this as a bug.
- Just for the heck of it, we tried importing the same video clips in Adobe Premiere Elements and that worked just fine.
1. Try setting your video resolution to "fine" or "super fine" in camera.
2. Try using Adobe Premiere Elements.
3. Pray that we get a fix in Premiere Pro soon.
4. I'm looking for recommendation for a different video camera that will work "out of the box"
Try any HDV/P2/XDCAM camera, and if you are in for a more powerful PC as well, any AVCHD. I recommend the XDCAM-EX3 personally.
Have you tried re-naming your .mp4 file with an .mpg
see if that works.
It doesnt work for all avc1 but might work with yours.
its worth a shot.
Thanks for the suggestions. I appreciate all the help I can get making sense of the wild world of video cameras.. The XDCAM-EX3 is a little pricey for my 11-year old son. HDV might be the way to go for now. We'll try to stay away from AVCHD.
Thanks for your suggestion, Glenn. I did try changing the file extension and it did not work for me.
