Advices CCE settings w/ DV-AVI ???

[hattia]

Hello,

I'm kind a newbie and I would like to get some feedback from people who are using CCE to reencode their DV-AVI files.

Actually, my CCE settings are following :
-upper field first = YES
-linear quant,
-zigzag,
-progressive,
-DC precision = 10

-GOP n/m is set to 4

-image quality priority=5
-noise is turn off

I'm sastify with the result but ...maybe....I can improve it by better tuning up my CCE settings ??????????????


I was told that for DV-AVI format, it is better to set GOP as 3/5 ??!!



Any advives will be appreciated

thanks

Is your DV progressive? Most cameras shoot interlaced.

Obviously your target format shall be MPEG-2. Do you wish to create SVCDs or DVDs?

bb,

My target is DVD. And I set Mpg2 format in CCE settings.

My camcorder is Canon ZR40. I have not found in the specification if it records in interlaced mode ?!.

I tried to look the properties of my generated DV-Avi files with Windows media player...but it doesn't say if it is 'interlaced' or 'progressive'...

Do we know some kind of AVI Infos viewer to get this informations ???!

thanks

Bitrate Viewer maybe? I'm not sure if it reads DV. Normally though you can spot an interlaced file visually by pausing the movie and stepping through a few frames. If you see jagged edges every couple of frames then you are dealing with an interlaced file, but if the image is clean in every frame then you have progressive.

Your DV file is most probably interlaced. Progressive scan is (unfortunately) a rare feature which is supported only by a few camcorders like the Canon MV3.

If you watch your DV file, e.g. using Windows Media Player (6.4 preferred), then make sure you view the video at full size (720x576 for PAL, 720x480 NTSC). You find the settings under Properties, when you have a DV file open and paused. Or open it in VirtualDub, and look for jagged edges. I'm almost certain you'll find them easily (look for scenes with movement).

If your video is interlaced, then encode in interlaced mode with a reasonably high bitrate (interlaced encoding needs a higher bitrate than progressive). Thus do not check "progressive".
