Difference between miniDV and AVCHD...

Hi.



My main question here is that when I'm applying the slow motion effects on footages captured using my new flash-based camcorder, the video appears jerky. [Footages without slow motion appears clear]. Some background info below:



I've been using Premier Elements 4 and recently version 7 to do all my video editing work. My old videocam used miniDV tapes and when working with these footages I can simply download the footages using Premier Elements using the PAL-DV project settings. I can work on the footages adding effects such as slow motion and the final DVD appears clear, smooth and fine.



HOWEVER, I recently bought the new Canon HF11. When working with these footages, I select the PAL-AVCHD project settings. Almost all the final footages (output to DVD) appears very clear and smooth with the exception of the footages in slow motion - it appears very jerky.



I thought that the jerkyness is caused when you choose the wrong project setting (ie. upper vs lower field first) - by choosing the PAL-AVCHD project setting, I would've thought that it should be fine.



The way I'm able to get around this is to deinterlace the footages with the slow motion effect. My question is why do I need to deinterlace the footages when working with AVCHD, considering that I do not have to do this when working with footages from miniDV tapes? Am I doing something wrong or is this how AVCHD works (ie. have to de-interlace slow motion footages?)



Just trying to understand how this whole AVCHD format works, etc. Thanks in advance.

Can you confirm what the specs I'm finding seem to say: This camcorder records AVCHD at 24p?



That non-standard frame rate could be the issue.



Also, how are you getting the video from the camcorder into your computer? Are you using the Media Downloader in Premiere Elements or other software?

Slow motion effect also looks poor when using standard definition MPEG2 files instead of DV-AVI... perhaps it is the compressed nature or file structure of the MPEG2/AVCHD that causes the problem.

Here's the specs of my camera:

Looks like it's AVCHD at 25p (or 50i)



I'm copying the files directly to the computer - ie. plug the camcorder to my PC, an external drive appears in Windows Exploer - I just copy the MTS files to my PC.



I just did some more testing and even de-interlacing it doesn't fully fix the jerkyness of the final footages on DVD.

Paul has a very good point.



Though you may be able to minimize the jerkiness by right-clicking on the clip and selecting Frame Blend.



I just don't think, working with MPEG4s (and assuming you're using all the correct settings), you'll be able to do seamless slow motion.

From what I can see, I'm using all the correct settings.



I'll need to try the Frame Blend option - never tried that before - all I've tried is de-interlacing the slow motion footages which fixed some of the jerkiness.



Thanks for your help.
