AutoGK Problem with bitrate and standalone player

[clarenceb5]

Hi I'm new here, but I've been familiar with DivX and XviD for some time now. I have a standalone dvd player that plays DivX and Xvid files it is the Kiss DP-500 model. The problem I am having is my player won't play DivX files with a bitrate greater than 3 mbps, I have contacted Kiss Technology asking them if this will be a fix in future firmware releases but I have not gotten a responce from them on it yet.

I have been using AutoGK for about a month now, in my opinion it is the best and easiest tool for converting my DVD's to DivX files. Because I use a standalone player I don't really care much about file sizes so I make most of my DivX files with AutoGK and I use the "Target Quality (in percentage)" feature and I usually set it to 100%. Most of the resulting avi files have been under 3 mbps bitrate but a few of them have resulted with bitrates higher than 3 mbps, my question now is: How can I find out what the resulting bitrate will be before I start the conversion process? I'm greatful that the tool is available for me to use but I'm not liking the fact that I have to perform the conversion which sometimes can take up to 8 hours on my pc before I find out what the bitrate is going to be. I've tried bitrate calculators but I don't understand them or all the features they have built into them. Is there something I can do to find out the bitrate of the avi file before I perform the conversion?

Sorry if this issue has been answered already, I've been searching the forum for the last week looking for an answer to my question but I have been unable to so far.

Thanks in advance for any help I receive.

It's not an AutoGK issue -- it's a codec configuration issue. Quality based encodes do not have fixed bitrates, nor do they have bitrate limits. Instead, they use fixed Quantizer values for encoding the images.

For example:There are hardware players that are "DivX Certified" to a particular level of compatibility. "Home Theater" is a level for some DivX certified DVD players, and it has a maximum bitrate of 4000kbps. Because of that limit, quality based encoding is not available when encoding for "DivX Home Theater Certified" players.For much more on codec settings, Quantizers, encoding algorithms, and the like ... click on http://www.divx.com/support/guides/DivXGuide51.pdf

Hi-

How can I find out what the resulting bitrate will be before I start the conversion process?

You can't, not when using Target quality (in percentage). You'll have to use 2-pass encoding for a Predefined or Custom size. That way you can use a Bitrate Calculator (I recommend GKnot) to figure the final average bitrate. Just plug in the length of the movie (given by DVDDecrypter) and the bitrate of the audio (also given by DVDDecrypter, if using the AC3, or determined by you in the Advanced Settings, if MP3). Then fill in the file size to get the bitrate, or the bitrate to get the file size. But doing it this way still won't protect you from bitrate spikes. I have some videos with higher than 3000 average bitrate that play fine on my standalone. But I also have many with much lower bitrates that will freeze for a short period when the bitrate skyrockets temporarily.
