Re: Question regarding blockiness at outer fringe of video frame
by Mike Konstan on Aug 29, 2008 at 1:29:57 pm

They tried re-encoding the file using ProCoder on the PC, and got rid of the problem. Of course, they just cranked up the bit rate super high and that's apparently what did the trick.

My file was encoded at around 1000 kbps because they originally wanted to keep the quality up but the file size small since there were many videos to include in the presentation. The settings I used seemed to be the best compromise, it's just that we started getting the blockiness on the edge on that particular PC. That file was also difficult to do since it involved slowly sweeping lighting effects that revealed product features in black limbo.

I checked their re-encoded file and the bit rate was all the way up to 16,000kbps! The guys just used the "High Quality VBR" setting in ProCoder and cranked up the Quality setting to 100% as well. So the resulting file looked great, the bit rate is super high and the file size nearly doubled to about 52 mb.

I think they could have increased the quality without taking the bit rate up quite so high-- seems like overkill on the data rate. But it works for them...

Thanks again for your help with decyphering these issues, Daniel!
