Final .AVI size wrong?

[Killstun]

I have just tried to make my first 2CD DivX movie with GKnot. But I'm running in to trouble when it comes to the final .AVI size. The outcome is only about 900 MB instead of 1300 MB. How can that be? Is it because I'm not running a compressibility check? The GKnot log is shown below:

(I'm doing the audio seperately, and have checked 'No audio' in setup)

I was about to post the standard answer: read this (http://forum.doom9.org/showthread.php?s=&threadid=24584) and come back, when I noticed the following lines:

Have you checked the size of the files Liar_movie.avi and Liar_Credits.avi? If they are the right size, then try join them manually (and add audio) and see if it turns out the right size. If not, do a compression test and see what the result is. Do remember that some people have reported saturation with as low compression ratio as 60% when B-frames are enabled. If you ask me, I think is looks like overkill doing a 2CD rip at 640x336 when the movie only is 1h23m.

[Killstun]

The file Liar_movie.avi is also in wrong size, but you gave me a hint with the overkill. The reason why I wanted 2 CDs for this "little" movie is because it deserves it ;-) - but I have done a compressibility check, which give a huge indication of overkill. Red box appears next to 'Load ->'.

I have now made the resulution bigger, and can come down to 0.338 in 'Bits/(Pixel*Frame)'. Could that maybe be enough for the rip to be much closer to 2cd's? I have read that the optimal thing is to stay around 0.25 for 2cd's, but don't have any experience with this.

[hakko504]

0.338 bpp sounds good to me, have you made a compression test at that resolution?

In my experience, most films will turn out fine as long as the
compression test shows values between 60-80%, regardless of the actual bits/(pixel*frame) value. If the bpp value is high (0.5 or higher), they will usually look OK with compression ratio down to 40%. If the compression ratio is higher than 80% (DivX3:100%) then you will most likely get saturated movies and not reach your target size, so at that point you should either increase resolution or decrease number of CDs.

[PeterTheMaster]

this happens all the time. i didnt have a single case where the intermediate files were deleted. maybe there is some synergy with the avi overheads or its because of the clustersize of the filesystem.

I was very perplexed by this when I first saw it happening on every one of my rips, so I did some investigating to find out why. This happens when you are not muxing the audio into your video. The overhead on each AVI is 8192KB and you lose this amount when you join two AVI files. If you have GKnot mux in the audio, no error message because of the interleaving.

[Killstun]

I will try to make another one without the AVI overhead box checked. Will then hope that this will get i right, because I really need to encode audio seperately. This also maybe the solution to another problem, when I'm melting picture and sound together. I will return tomorrow again ;-)

[PeterTheMaster]

i never let gknot mux because i use ogg (yes: vorbis).

"I will try to make another one without the AVI overhead box checked."

will not change this. i had this box checked in the past. i dont do it any more because i use ogm (yes: ogg)

seems like Wef made a little mistake, this error shouldnt occur in case of
movie + credits < both
but
(movie-8k) + (credits-8k) < (both-8k)
(if that 8k is correct)

how can this be cause of another problem? the only thing it causes is that the intermediate files pollute your harddisk until you kill them manually.

[Killstun]

Did not get the first part you wrote, but my problem was as you said when movie + credits are being merge. The other problem I mentioned has also been solved. It was because of an audio error I made myself with the Mp3 codec :-(
