Re: No valid Source when opening H.265 file

This is another case of our PS demux mistakenly recognizing an mp4 file as PS. I won't have time to do a deeper dive to see if there is anything we can do about it for a couple of weeks. But this should be added to a github issue so it doesn't get overlooked.

Re: Constant framerate not constant?

This discussion comes up all the time. Every framerate can't be represented perfectly by the clock HandBrake uses internally. HandBrake uses the standard 90khz clock used by all transport streams and program streams. This is the same clock used by all broadcast TV, Blurays (including UHD), and DVDs....

Re: Include sub folders when selecting source folder?

It's not possible. There are lots of complications when dealing with multiple directories of files. I chose not to deal with those complications when initially writing batch support and haven't had the motivation to go back and work through the issues to enhance it.

To be clear, we are not against SRT passthru support. It's just not high on anyone's priority list and there are lots of other interesting things to do.

Ugh, I stated something backwards. "Align A/V start" *prevents* the insertion of an "empty edit". Empty edits confuse some players.

Re: Encoding shifts video 2 frames back

Is this an intermediate file that you will be re-encoding again? If so, why placebo? For intermediates, it's a whole lot faster to just use more disk space to preserve quality. Even if it's not an intermediate, placebo has it's name for a reason. The amount of gain you might get with placebo can be ...

Re: why you said 18 to 20 crf for standard ??? and 20 to 23 for hd ?? non sence!!

For SD content, you are starting out with a low quality source. If you want to refrain from degrading much further, you use a lower RF. For HD content, you could apply the same logic as above. I.e. "you want to refrain from degrading it much further". But this is overkill for the vast majority of pe...

Re: Encoding shifts video 2 frames back

1. Ultrafast is "less effecient" at compression. What this means is that for a given desired quality, the filesize will most likely be larger. The quality slider only provides a rough control of the actual output quality. Changing other settings (e.g. changing from placebo to ultrafast) slightly cha...

Re: Encoding shifts video 2 frames back

I had a look at the files you supplied. Both the uncompressed and encoded version have 968 video frames. When I single step through both the original and encoded version, I see the logo appear at frame 14 and hear a blip at frame 17 (playing back with mpv). If I had to guess, AE is ignoring or not p...

Re: Encoding shifts video 2 frames back

The encoded output definitely has 6811 frames, from your log: [00:03:46] mux: track 0, 6811 frames, 1304093854 bytes, 36725.28 kbps, fifo 512 This line in the log comes from the muxer (very last stage in the encoding pipeline). It counts every frame that gets output. How are you determining the numb...

Re: 10 bit vs 12 bit video opinions

If you run your own tests (as MiniSiets has done), you can see the difference in both quality and file size of 10 bit vs. 8 bit encoded content even when starting with an 8 bit source. The visual differences are most pronounced in flat-ish backgrounds and darker areas where an 8 bit encode will typi...

Re: Encoding shifts video 2 frames back

Do you know how many frames are actually in your original video? The log says the duration is 4:44.07 (284.07 seconds). At a framerate of 23.976, that's 6810.86232 frames. The log reports that 6811 frames were output. So the numbers all add up. Nothing missing according to what's reported in the log...

Re: how do I extract SSA/ASS subtitles

Ahh, that explains it. DVDs can have CC "tracks". CC are special in that they are not really separate tracks at all but are embedded in the the video track. HandBrake detects their presence and presents them in the UI as a subtitle "track" and labels the track "Closed Caption". CC are text and HandB...

Re: how do I extract SSA/ASS subtitles

To clarify Woodstock's comment, DVD (and BD PGS) subtitles are images. SSA is text. To convert from the images to text requires optical character recognition which HandBrake does not do. We require an activity log of your encode to help you further. Your description of your problem makes no sense be...

Re: How to find movie name with cli

The title is sometimes available depending on the source. BD and DVD often (but not always) store the title in the volume info. Other formats often have the title in metadata tags. The CLI doesn't show this by default, but there is a "--json" option that outputs status information including the full...

The log shows that it created 2 audio tracks and that data was written to those tracks. There are not other similar reports, so it's unlikely that the data is all silence. But maybe you gave us the wrong log? You said the audio is mp3, but in this log the source audio is AAC and the 2 output tracs a...

Re: Telecined material filter help.

What mduell said... Also, I've never seen hard telecine in a 23.976 fps source (it's soft telecined if it's a DVD source). It would be very unusual for there to be a mix of hard and soft telecine in the same source.
