HandBrake

You might want to disable "Foreign audio search". It automatically adds any subtitle track that looks like it may have subtitles for a sequence with foreign audio. In this case, it interpreted the forced subtitles in a track (which are probably the watermark you are seeing) as potential fo...

I'm not even sure why Handbrake is increasing the bitrate since I doubt it's increasing the quality You assume correctly that HandBrake can't increase the quality. When a video is recompressed to a "higher quality" than the original, all you are doing is faithfully preserving all the comp...

Is it possible even when I cut a clip from a middle of a longer movie? Both video and audio are well underway so start time should be irrelevant. In this scenario is is almost guaranteed that the start times will not align. Audio frame and video frames have differing durations. So if you start an a...

I did do a quick check this time to see how much trouble it would be. ffmpeg supports reading compressed PGS. But it does not support writing compressed PGS. So I'll have to patch ffmpeg to add this feature. Probably a day's work at worst. Just have to set aside my work on OctoPrint and OctoDash for...

In media files, it is possible for the first audio timestamp and the first video timestamp to be different, e.g. the audio starts at time X and the video starts at time Y. Align A/V start shortens or extends the duration of the first video frame to force X == Y. If the original difference in start t...

HandBrake has a convenient "Interlace Detection" filter that may help in this scenario. When this filter is enabled, it looks for combing artefacts in the incoming frames and marks the combed frames. The information about which frames have combing is fed through to the "Deinterlace&qu...

The PGS track is compressed in the zlib format in mkvmerge file, but uncompressed in the HandBrake one. That's interesting. I didn't know that was an option in mkv. It certainly would save a lot of space. Will have to look into adding support for that since zlib is already one of our dependencies. ...

But why isn’t there info about bitrate of video and audio streams (in MKV from HandBrake), please? Not sure really. The matroska specification has no track elements for bitrate, but it can be calculated from duration and size of the data in the track. Matroska does have "Technical Information ...

Unfortunately, HandBrake's detelecine filter doesn't have any logging that could tell us more about what might be happening. I really should add a verbose logging option so we can see if there are any breaks in the 2-3 pulldown pattern. But that looks like what is happening. If you are really intere...

Is there a reason you are choosing to encode to MPEG-2? If you don't require MPEG-2 for some player compatibility reason, you should use a more modern codec. The MPEG-2 codec is old technology (nearly 30 years old) and the encoder implementation (i.e. the software implementing the spec) is much less...

Is there a feasible reason why the default 1080p preset would have automatic cropping set 268 to the right? This is my fifth time using the program, and it wasn't there previously. Because commercial formats have limited allowable resolutions. So when the video is mastered, they add black bars to m...

Ok i give up. I think i’ll need an activity log here even for asking if truehd atmos its better than a 64kbps mono mp3 or for just to say “hello”... Yes. They are easy to generate, give details most people don't know are needed and prevent miscommunication between people that often don't speak the ...

No way to know from the information you've provided.

We really need to see an activity log to understand what you are doing. But the "auto" anamorphic mode keeps as many pixels as possible of the original source while adhering to any other limits that other settings may impose (like the "Resolution Limit" setting). So, for example,...

Try a software encoder rather than NVEnc hardware encoder.

Are you using the flatpak we publish? Do you use gnome or kde desktop?

There are a couple of ways. Use encoder "levels". Levels are designed to tune encoder settings to match the capabilities of a player or playback environment (i.e. streaming). Levels implicitly set "VBV" settings that limit bitrate. Information about levels https://help.encoding.c...

What tool are you using to measure HandBrake's output framerate?

If you are worried about spikes causing playback problems, then you should be using encoder "level" or VBV settings to limit such spikes. For example the level used in the activity log you provided (3.0) limits peak bitrate to 10Mbps. As far as I know, this information is not available fro...

Okay.. I will stick to doing "Same as Source", CFR, and checking the logs to make sure no duplicates or frames were removed or added, etc. I saw some people in another forum (and maybe another program other than Handbrake) talking about doubling the frame rate if you are deinterlacing... ...

DVDs are CFR only if you apply pulldown flags (soft telecine), otherwise they can be VFR. Since pulldown flags are intended for playback on an interlaced display and otherwise introduce combing artifacts, HandBrake does not apply them. Actually, HandBrake does apply the pulldown flags. But applicat...

The crop marks unfortunately were removed when we improved the ability to render filters in the previews. The crop marks were added by the GUI after all rendering. With the new pipeline, it's more difficult for the GUI to know how to position and scale them. What really needs to be done to bring the...

Error 12 is an out of memory condition. I.e. it attempted to allocate some memory and failed. This is typically not a problem at the resolution you are encoding even for very modest machines. How much memory does your machine have? What other applications are you running? Have you tried rebooting la...
