HandBrake

just found a thread that is about the same issue:
viewtopic.php?f=11&t=30407

do you need a sample file?

I can easily provide one

Many TV Channels switch between 2.0 and 5.1 channels on-the-fly. Advertisings are send with stereo audio but movies often with 5.1 (surround sound) the issue is that often the channels start the first seconds of the movie with stereo sound but switch to surround then. If you want to keep the credits...

nice idea, could be helpful
and showing a little bit extra information shouldn't hurt at all

Hmm, VP9 is supposedly 7% faster than H.265, or so I read somewhere. Well they claimed that for VP8 in comparison with H264 already. Which obviously didn't end up right... H264 - as implemented in x264 - is way faster and is way more efficient than VP8 in any implemented form. We will see whether a...

he doesn't want an option like "pls stay below this file size", but a bar/text next next to the avg fps that shows "current avg. Bitrate * length of the movie" which shouldn't be hard to implement, right? of course it isn't accurate, but he was asking for an estimated file size i...

the progress of the preview encode should be shown in the taskbar

They are just guessing at this point with regards to VP9. Is it about me? Anyway, x265 might be usable in 2020 if not after. But till there I'd like to see an alternative thing to shine more (VP9, YkT, Daala). Very unlikely, as money is their biggest (if not the only) motivation. what is YkT? I hav...

you should try out Subtitle Edit instead ;) it works awesome for me and you can use a wide range of formats as in- and output ->you could export .ass to .srt for example you can see the subtitles directly on the video and sync them with the video if they are asynchronous and to top it off: it's open...

some interesting looking ones that I found: http://www.ee.cityu.edu.hk/~lmpo/publications/1996_IEEE_TCSVT_4SS.pdf http://www.snellgroup.com/documents/white-papers/Motion_Compensated_Frame_Rate_Conversion_White_Paper.pdf http://www.snellgroup.com/documents/engineering-guides/emotion.pdf https://www.g...

ok
as a general threading for several filters or just for this one?

is someone working on a threaded version of nl-means at the moment? / how likely is it that someone will take care of this in the future?

For the quality setting estimation might not be possible, but if you choose a file size over 4gb or set the average bitrate to a value that makes the file size exceed 4gb then there should be a notification/error/abort (average bitrate/s*runtime of the movie=estimated file size) EDIT: scrap what I j...

a portable version is a nice idea

just a quick notice: CLI versions are already available as .zip acrhives, so this is probably about the GUI, right?

OK then forget about it, all formats for my needs are supported anyways

What do you think about implementing more input formats for subtitles? If someone is interested he/she could acquire knowledge from Subtitle Edit (open source, GPL): http://www.nikse.dk/SubtitleEdit/ https://github.com/SubtitleEdit/subtitleedit Subtitle Edit can read, write, and convert between more...

Yep, thx Just wanted to list further scalers and info about scaling algorithms, If somebody who is interested in implementing it into Handbrake/FMPEG, he might find it useful A book about a super resolution algorithm with subpixel motion estimation (starts at page 229, but you need to buy the book f...

What do you think about implementing an option to convert your video file from 2d to 3d? I know that software-based solutions weill never beat real 3d recordings/videos but it's at least something. Article about an Avisynth script: http://www.maximumpc.com/article/howtos/how_upgrade_your_2d_movies_3...

Having some experience with super resolution algorithms, I can say that the results are typically not dramatic if you're going for a natural looking upscale. Animation excepted, of course. That said it's cool tech, and patches as always, are welcome. I've not yet found an open source implementation...

Will look out for open-source super resolution filters. But the open-source-code for all scalers for animations are available at the sites presented in the quote above, it's all GPL or LGPL, I think ;) (Just click on the links and your browsers takes you to the Google code pages containing the sourc...

Another interesting link about this topic:

And a German paper about it:

Lol I had to Google that codec :lol: Never heard of it before. Of course there is no way to do that but I didn't ask for it as I don't have any videos encoded by VC-1. (There is also no way for me to use the new opencl bicubic image scaler as I'm using a nvidia card, but I'm not complaining. -> ther...

Ok sorry for wrong statement then and thx for your correction. I don't know how it is now as I only use Vidcoder and helped translating it into the German language, but at the time I switched to Vidcoder the Handbrake GUI for Windows didn't support pausing encodes which was one of the reasons why I ...

Are you talking to me or epstewart?

My source frames are encoded either in H264 (HD) or MPEG-2 (SD) ->TV recordings: Transportstreams

Handbrake supports both so that it should be possible to just pass most of the frames through if they are OK.

What do you think about implementing further image/video scaling algorithms? There are so called "super resolution" scalers out there with and without subpixel motion estimation which could enhance video Quality a lot and guess informations from nearby pixels so that scaled videos would lo...

Would be nice to have at least a "partial" video passthrough -> advice the handbrake core to reuse existing frames, but if there are a/v sync errors reencode the particular scene. You wouldn't be able to change the framerate or use filters and stuff but it would result in a working video p...
