Hello,

The HDV I capture from my cannon XH A1 via Firewire is very grainy and pixelated (see attached photo).

PD Version: PD 9 Ultra Trial 9.0.0.2701

1. Under the Capture tab I am able to preview and record the file. The preview of the file during the capture appears to be very high quality.

2. After the file is captured, if dragged into the timeline, viewed in the Media Viewer (at Full HD resolution) or rendered, the file is extremely pixelated.

What has worked:

1. successfully captured HD quality video using 3 differents brands of editing software.
2. I was able to import these files captured by other software into PD and the quality looked great.

This leads me to believe that it is a problem with the capture step within PD. Any ideas?

Thanks!

GG

After you save the capture, open it with a program like Media Info and look at the codec and bitrate. __________________________________

Thanks for the reply:

Here is a MediaInfo report for one of the pixelated files I captured through PD9:

Does it look that bad even when played in other media players or produced to a video? I don't see anything in the specs that would cause it to be poor quality. Have you tried changing the capture profile to see what happens? __________________________________

I am having the same issue and see no resolution anywhere in these posts. My camcorder is a Canon VIXIA HV40 HDV. Great quality when hooked directly to the TV.
