viewing a QVGA/VGA resolution video with NTSC DV resolution (with a TV)

[Lightbreaker]

I have questions:

What will you see if you edited a QVGA or a VGA resolution video and to be viewed on a TV (which in NTSC format)?

Is it chunky? is it blurred? Because I'll edit a movie with a low-resolution camera (low budget) and I have VGA resolution digital camera at 30fps. I'll present it to my prof.. My only worry is having low-quality frames.


Thanks.

Explain what you mean by (QVGA = 320x240?) or (VGA = 640x480?) resolution? What bit depth? Uncompressed?

640x480 can be higher resolution than NTSC but resolution is only part of picture quality. Most "low resolution" cameras don't fill the 640x480 raster with quality video. Key issues are lens, chroma separation, optimal RGB processing.

352x480 can look quite good on NTSC TV when interlace is preserved from the camera to the encoded file. 320x240 must be progressive and needs upscaling to 320x480 for interlace conversion to NTSC. This can cause blocking on edges and other upscale artifacts.
