Patch to hb_fix_aspect

Proposed patch to hb_fix_aspect: 1) Increases the minimum dimensions from 16px to 32px avoid crashes related to small dimensions. 2) Consolidates hard coded modulus into one variable. It's cleaner, plus switching to something other than mod 16 is now easier (at least as far as libhb is concerned). 3...

Re: High Profile

That's exactly why we ask for an activity log. Sorry I missed it in your short paste.

For the record, ac3 is supported in mp4.

Anyway, glad to hear you got it sorted.

You probably need to switch the other options as well. -e x264 -q 20.0 -a 1,1 -E ac3,faac -B auto,160 -6 auto,dpl2 -R Auto,48 -D 0.0,0.0 -f mp4 --detelecine --decomb --loose-anamorphic -m -x b-adapt=2:rc-lookahead=50 Still, this is unconventional and may not work.

Re: [SVN 1797] 6-channel AAC input does not work

Status update:

j45 has provided a patch http://handbrake.fr/pastebin/pastebin.php?show=1069 that will allow HandBrake to downsample 6 channel aac input to 2 channel, a workaround to this bug until proper 6 channel decoding and/or passthru is supported.

Re: x264 + xbmc + original xbox

vbv-bufsize and vbv-maxrate are to be used together, and do work in constant quality mode. They are most useful when you know the buffer size and bitrate limits of a hardware decoder. Getting it right with a software decoder can be difficult and different settings may be needed for different softwar...

IMHO that's a bit too restrictive. However, I would enjoy seeing that in a tooltip for the slider control.

I'll prefix this with the fact that I previously worked at a video production company, and I do a lot of work with video today. Most of my workflow is uncompressed.

Re: WinGUI - preset with Constant Quality=100 is not restored.

Quick note to add: Despite the obvious point that using RF 0 is silly, the bug mentioned is probably legit. I'm guessing that there is a comparison against 0 instead of null/nil, causing a value of 0 to be seen as RF not set, instead of set to zero. +1 for removing % display in the GUI, in favor of ...

Re: WinGUI - preset with Constant Quality=100 is not restored.

RF values greater than say, 18, only increase bitrate and provide no humanly visible quality gains. x264 developers have said many times that RF 19.25 is near-transparent to the source for SD content. On HD content, an even lower RF may be necessary. I have a Panasonic GF1 and I shoot all videos as ...

Re: SDTV ~ CRF Filesize Wars

First, let me say that I always appreciate it when people do their own testing. However, much of the information you present here is not very useful, and some of it downright incorrect. Take for example your assessment that "The standard movie-size on the net is around 720mb XVID". I know exactly ho...

Re: Encoding from point A to point B

+1 for letting the user determine chapter markers. Worst case is the output will not begin with a chapter marker, but this should be expected behavior.

Re: Re-coding mp4/aac5.1 for iPod Touch produces weird result :(

I should mention, the language being "und" or "eng" is probably not the issue. Rather, I'm calling attention to the lack of a bitrate listed in the former example, as well as "5.1" being used rather than "6 channels".

Re: Re-coding mp4/aac5.1 for iPod Touch produces weird result :(

I've been trying to narrow this down a bit. The audio in your source is read by ffmpeg like this: Stream #0.1(und): Audio: aac, 48000 Hz, 5.1, s16 However, in my testing, what HandBrake produces when selecting 6-channel discrete AAC output from AC3 input is read back by ffmpeg like this: Stream #0.1...

Re: How to determine bitrate?

An encode at RF=19 or lower should be damn near transparent to the original source. Going lower than RF=18 is practically pointless. Quality and bitrate are only loosely related, and you most certainly do not need anywhere near 15GB to do a decent hidef encode with the latest x264. 5mbps x264 is inc...

Re: Encoding from point A to point B

I can verify that on most sources (various containers and durations) this does appear to be start-time accurate within one second, and produces the requested duration. With transport streams the start time can be off by as much as 30 seconds or more, but this is expected given van's comments: http:/...

I hate to supplement what the other devs have written, but I think it might be all of this "bit" talk that's confusing people. If you have no idea what a bit is, this is for you. There are 8 bits in a byte. There are 1024 bytes in a kilobyte (kibibyte, proper). There are 1024 kilobytes in a megabyte...
