Canon GL2 question
|
Can't Post

|
I bought my first miniDV camera. It is the Canon GL2. I like everything about it except 1 thing. The issue occurs when I put it in normal mode and shoot diagonal lines. Examples that i noticed it on was shooting building roofs, painted parking lot lines and a dark table in my house against a light colored wall. When the camera is stationary, the picture looks great. But when I pan, the lines start to look jagged.
It looks to me like the camera writes over odd lines with one picture, then even lines with the next one. I'm not sure if this is an effect of interlacing?
I notice the issue heavily on my computer, noticebly on my 32 inch (normal NTSC, not HDTV) TV. And can't see it in the lcd monitor of the camera or a small 13" monitor. The pictures looks good in the small monitors.
When I went to the camera store I bought the camera from. The salesperson ran the video through a Small monitor and said it looked good so there was no problem. When I showed him how it looked on the computer he said that was a problem of the software (I burned a video quality mpeg with pinnicle 8). He could see the problem (as it was obvious on the mpeg) but said it wasn't the camera doing that even though it showed up in the first take on "Normal Mode" but not in the second take on "Frame mode". He said the "software is 8-bit and the camera is 16-bit" which causes the problem on the computer. He did say though that he never tried putting his on the computer. He has the same camera and says his works perfectly in Normal mode. He did let me shoot with his camera around the store and then the same shot with mine. When I brought the tape home and viewed it on the 32" tv, they did look about the same but there was no diagonal lines or sharply defined lines to really compare to.
When i shoot over grass and things like that where nothing is sharply defined, i don't notice the problem though i assume this is happening over the whole picture.
My QUESTION is:
Is it normal on the Canon GL2 to have this effect in Normal mode or is this a defective camera? Since I don't have another digital video camera, I have nothing to compare it to. Also, if this is normal, is this an effect of interlacing?
Also, just to clear up, I am running the video, it is not paused where i am seeing this.
