View Full Version : Bad jaggies and combing....

OK, I'm not sure if this is an "interlaced" vs "progressive" issue or not, but here's my question.
I shot about 50 minutes of video from a 90th birthday party at the beach several weeks ago. I used a small Canon point and shoot set to video. I am amazed at the very good, close up, PQ that little camera puts out. Nothing like a GL2, but very good. It is an AVI file and I processed it in Adobe P.E. 3.
For some strange reason, when I play back the burned DVD, the picture has a lot of jaggies and what I think is combing. In other words you can see the ends of the scan lines especially where there is a contrast difference.
This is most noticable on my 23 inch LCD display.
Any suggestions to smooth out the next burn??

Tom,
Back when your DVD-VIDEO was only at the Preview before Burn stage, did you see any traces of this "edging"?
Have you tried a soft Gaussian blur effect?
You say that you have a Canon point & shoot camera, and you say your movies are AVI. Are they DV AVI or AVI Motion JPEG? In these cases, if you are not placing DV AVI on the Timetime, have you tried converting your Timeline content to DV AVI standard (File/Export/Movie). If your Canon is offering you an AVI widescreen option, you can still use the File/Export/Movie route to the DV AVI widescreen, just change the aspect ratio in the Settings for the DV AVI export.
Please let me know what happens.

OK, it comes from the camra as an AVI file. That's all it says in the properties : AVI.
No widescreen option. That's really not important here, 4:3 is fine, unless there is some reason that widescreen would be better.
I went back and looked at some video I shot last summer with the same camera and it is fine. No jaggies, no combing, you can't even see the scan lines.
Yes, ATR, I can barely see the scan lines in the Adobe editing monitor. I can't figure out what is different now from last summer. I'm shooting the same frame rate and the same size.:confused:
It is possible that I used Windows Movie Maker last summer to process the video and saved it as an AVI movie........ but what difference could that make? This looks so bad to me.

ATR,
When I read this, I have to admit, it went right over my head.... sorry.
Now I understand..... I'm working on it right now.
thanks again for your amazing patience. Tom B.

Sorry for the slow response. I went for a two day visit to my home state where I was gifted with old equipment with which to "play". More about another time.
There are all sorts of AVI, example DV AVI, AVI MPEG4, etc, etc. AVI is considered the wrapper; whereas, DV and MPEG4 would be compressor types. DV AVI is the way to go for Premiere Elements. You could use Windows Movie Maker for conversion to DV AVI or Premiere Elements File Menu/Export/Movie for that task...depends.
Check it out and see what happens. If "negative", we will move on to plan B (as of yet undefined).
