where are the B-frames?

[drcl]

Maybe I'm misreading the log files, but the frame sizes indicate auto GKnot isnt using b-frames. I'm using Xvid which came with it. I reset to defaults before doing any encoding. Xvid seems to reset to simple @ level0 after I have encoded a movie.

Can anyone tell me how to make AutoGKnot use b-frames?

[unskinnyboy]

Post your log file please.:rolleyes:

If the compressibility test gave a whopping high value, AutoGK will switch off b-frames to avoid undersizing - which is probably what happened in your case.

The other ones are too large

[unskinnyboy]

If this is your log file, then definitely B-frames were used. Whatever made you think otherwise? Can you explain what you meant by "but the frame sizes indicate auto GKnot isnt using b-frames"?

Open the .avi in GSpot v2.52 and see if indicates 'BVOP'.

maybe this is useful?

So that's it? Just I and P all the way? B never comes up anywhere in the stats file? That's weird.

I can't understand why something pretty basic as opening an .avi in GSpot won't work for you. Anyways, do this then - Rar the log file (since it is only textual content it should compress well from ~5 MB to ~1 MB) and upload it to http://www.bighosting.net/. I need to see the whole log file.

http://img155.exs.cx/img155/4315/clipboard012cr.jpg

It does seem as if it doesn't use any B-frames, but I am at a loss to explain why (It doesn't show in the log that it switched it off even).:confused: I will just wait along with you for someone more experienced to come by and shed some light on this.:)

[drcl]

Thanks for trying.

It isnt anything to do with ESS compatability is it?

[len0x]

I'd make sure you're using correctly installed approved version of XviD...

[drcl]

I'm just using whatever you supplied. I believe its XviD-1.0.3-20122004 Final Release. I had a later beta installed previously but I uninstalled that before installing AutoGKnot. I then reset the codec to defaults. I'm using AGK1.95 btw.

Even though I'm having this problem i still got a decent result from AutoGKnot, with a Divx3 like look, which I actually like.

Just like to say it's a great piece of software which really should be on the shelves.

[len0x]

If you open XviD codec settings right after encoding is finished - do you see b-frames checked or not?

[drcl]

I re-installed everything once more and from the virtual dub video graph I can see that B-frames are being used this time. No idea what I was doing wrong.

@Lennox

The codec was being set to simple at level 0 so b-frames are not available.

[unskinnyboy]

Immediately after the encode, the profile should have been at AS @ L5, how did it end up at S @ L0?

[drcl]

i did the encode twice. each time i reset to defaults. i dont know how or why it was set to that profile.

sorry len0x for calling you lennox
