Based on my experiences, BV shows the VBV buffer value incorrectly. It's always double in reality.



Nope, target bitrate was 3069kbps and the max 5000kbps.



And this often causes problems...

@Inc: I used AVS to crop, filter and resize and then MEncoder's noise (3th) before expanding so the noise is certainly only in the film pixel area.

(EDIT: Answering to Phil)
That seems to be the case. The weird thing is that the curve CCE-encoded video gives is not like the one that MEncoder gives when using the registered version.

The Q value at that point is -0.29, the green color gets all messed up with JPG compression :x

Ok guys, I'll get the pictures for you shortly.

DVDMaestro didn't complain anything so the encode should be ok. Funny how the bitrate can get too low as I encoded the movie as anamorphic and there...

It's a damn shame that MEncoder doesn't give the timestamp where the underflows occur. I just finished the encoding process and there's some 20-30 underflow errors 8O I'll try authoring a DVD in...

Phil, no problem :wink:

By the way, Bitrate Viewer shows really funny figures..Q is sometimes negative :lol:

That's the problem..quant 1 is generally considered A Bad Thing To Do since the quality increase is pretty much negligible compared to quant 2. The filesize just gets a lot bigger.

This also...

I'm currently testing encoding with MEncoder again (with the same movie), this time with min quantizer=2 to avoid buffer underflows and lmin=1. Now it seems that the encode will end up undersized...

:?: Could you explain me then how you get a framecount of 24 within a GOP setted in CCE? :wink:
CCE allows only a max framecount of 15 (even in NTSC) within a GOP.
Or ... did I miss something...

Well, in that case Mencoder's of no use to me as the main reason was the speed of CCE and ability to use 24-frame GOPs combined :cry:

I personally dislike TMPGEnc for DVD encodes since it takes...

That's because I wanted to make sure that the min bitrate is around 300kbps so my Pioneer doesn't get hiccups. I also didn't want the noise to be put on the borders and I was unsure which Blockbuster...

I used your latest CVS build (P4 optimized), 2-pass. The first pass doesn't show any underflows, they occur in the second pass.

I solved Phil's problem by cropping, resizing and filtering in the...

Buffer underflows

I've been getting some buffer underflows with my DVD encode tests, avg bitrate 2000-3000kbps. Is there any simple way to get rid of them or do I just have to use CCE for those encodes :lol: ?
