megui: oversized (huge) file with cq-profile

[Hobojobo]

Hi,
I am doing some tests with megui (0.2.4.1038 with latest updates) and the video x264 profiles.
I took chapter 15, the lobby shooting, from "The Matrix" (PAL-DVD)
The cq-asp_q2_eq(crf) profile returned a totally oversized file (413 MB without audio)

Is something wrong with the profile or ...?

--crf 0

you sure you didn't enter the wrong crf value or maybe you accidently clicked on lossless

[Hobojobo]

That's what I thought, too.
But uninstalled megui and downloaded all once again incl. the profiles with the auto updater, no chance to mess up the settings and did the encode again. Same thing. :confused:

Edit: When I open the video configuration dialog of the cq-profile the command line starts with --crf 18 --ref 3 --....
That is strange.
The log tells me, as above, --crf 0 --ref3 --...
Funny.

[Hobojobo]

Try this:
Select a CQ-ASP_Q2_eq(crf) profile
Open video configuration (config)
You can see the command line:
--crf 18 --ref 3 --mixed-refs --bframes 3 --b-pyramid --b-rdo --bime --weightb --filter -2,-1 --subme 6 --trellis 1 --analyse all --8x8dct --vbv-maxrate 25000 --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "" ""

Tick Lossless. The command line will change.

--qp 18 --ref 3 --mixed-refs --bframes 3 --b-pyramid --b-rdo --bime --weightb --filter -2,-1 --subme 6 --trellis 1 --analyse all --8x8dct --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "" ""

Untick Lossless again.
The command line should change. It should be identical with the default.
No, it does not do the trick.
It remains the same.

Is this a bug?

[Hobojobo]

I tested megui 0.2.4.1026 with the same settings as before.

log file shows --crf 18... and the output size is of course reasonable.

So it is a bug in megui 0.2.4.1038, I guess.
Can somebody confirm this behaviour?
