So, as you know, there are sites that collect HCG's, but I wondered about the next level, recordings.

So what makes recording H-Scenes an economical idea, you ask.

1. Low amount of change between dialogue means a (relatively) low file size, for instance

The GIF I have attached is 7MB in video format (I record 64k voices, but I'll get to that in a bit.) the GIF itself is 1/7th of the video file, a huge difference.

You might be asking why size is even important at all, well for that, I was thinking a mega-collection torrent or whatever you call it,

For now the scope of this idea is for english releases only, even that is an extremely large task.

So, GIF vs Video, first I'll go into my recording setup…

OBS, 10 QB (Quality Balance), Unlimited Bitrate, 30FPS (output flv)

GifCam, 1FPS (I wish I could set it to lower than that, but..) (Output gif) (By the way the GIF is 7 minutes)

Now, GIFs do not have the capability of videos, sound, time seeking, so even though t saves a lot of space, it is impractical, for now.

For GIFs to become a practical alternative, you would need a program that plays a gif, and two different audio tracks, and has seek function with synced audio, of course, very much doubt something like that exists. pity.

And so, video is the (practical) solution,

I record the scene with 64k voices and music turned off, then record the associated music with 128k in a separate file

1. this lowers the filesize by a large amount

2. it enables free control over voice/music balance

I do not have any averages for H-scenes per visual novel. Their length is usually between 7 and 15 minutes.

And so, I ask you, is there a demand for H-scene recordings, or is a pipe dream?

(Also, sorry if this is the wrong board, it's fairly relevant.)

> is there a demand for H-scene recordings?

Yes.

Anyway, I'll come back in a bit with all the (Bukkake Ranch) recordings. This one is actually a bit different, it has some of those animated scenes which drive up the file size a considerable amount, be back tomorrow, most likely. (About 15x3 + 5 scenes)

A large amount of scenes for my first sample, ah, well. I didn't want to choose any non-nukige because spoilers and all.

I hope that for non-nukige this idea would increase sales.

As for nukige themselves, well, probably the opposite.

Didn't get much accomplished, decent sample sizes, non-users file expire eventually, nobody will tell me when that is..

https://mega.co.nz/#fm/OBt1hJRL

Sarah - Service - MP3 is the BGM for the Service videos (As for the BGM's actual name, who fuckin knows?)

Sarah - Pleasure L3 is a test demonstration of a scene with an animation, with animations turned off, and accompanied Animation GIF,

lastly there is the project notes, full of things you don't really need to know.

Most importantly, I need to gather a group of people willing to help out, this is impossible for one person, especially me, my internet sucks. 2 Games a day at best,

If you know a board where I might find some help, please suggest it.

>Recording into gif.

Couldn't you just make recordings into webm and have them with audio while you're at it too. That seems a lot more convenient than having to deal with gifs of any kind.

This is a rip of the wmvs Lilith was using for their VN and then converting them into webm.

Sorry, I forgot I signed out of the temporary mega session, the files aren't available anymore.

To 3313, the GIF reason is because of filesizes, even on average we have like at least 10 H-scenes per VN, sometimes the bigger ones have 40, and it really adds up.

I never did find the magical software that could sync GIFs with music but I did find something I could use instead, VDUB, vdub that combines GIF files with audiofiles so the user can build the movies themselves, that way the user can have a convenient file while only downloading the 1/7th of the data that the convenient file is.

I will be returning in a bit with some more samples from a different game, I still have to work out how to incorporate VDUB into the equation.

Also lastly, if anybody here knows how torrents work I'd like assistance setting one up for the collection, I really have no idea.


 No.3478

I didn't know this was a thing, I'm glad to see others doing it. I've done a few recordings of scenes I liked, from the following VNs:

Gonin!? Pitari to Tekichuu! Kyousei Uranai

Gyakushuu 5

Lightning Warrior Raidy

Aku no Onna Kanbu 2

Dark Lord

Monsters Raid

13nin no Uruwashiki Kedamono

I record and encode with BB Flashback Pro 4. The average filesize depends on resolution, but it's about 30MBs for 15-20 minute scenes at 800x600, if I set the FPS to 4 (which never lowers quality, unless there's animation involved, since I always have the text speed at maximum/instant). 720p is at about 30MB per 10 minutes.

I guess you could lower the quality, though, if you wanted to prioritize a low filesize.

Back from the testing, I appear to have hit the color limitation of GIFs because these look terrible, oh well, I wanted to at least give it a shot,

1280x720p = 3mb/m would be about half for older 800x600 resolution stuff,… I think.

See attached file for why GIFs are not a viable alternative, Might want to redirect the idea into just the "better" scenes instead of every single one, given that we're looking at 150MB-700MB per game.

It's a shame, they really were so much smaller in filesize, but I couldn't in good conscience say these are good enough quality.

Will look recording as movie files, be back later.

Nah, I know who I replied to.

Using OBS to record so I can encode with ffmpeg later, still, I wasn't able to achieve a reasonable quality with your numbers, even with the important audio/music separation idea*

[Record voices at 64k and include the music separately at 128k, reduces audio size by half]

I'm not sure if your method can get much better quality at a lower file size or if your files look terrible.

>>3478

You claim to get 1.5MB-2.0MB, which is not something I could get with FFMPEG that still looked decent, can you provide some of your files? (also confirm or clarify your audio recording)

Here's Q7 which has a 1.7/min rate, somewhat pixelated.

FFMPEG says your audio bitrate is 85/k,

(85k * 15 = 9.5m of this file is audio~)

Anyway, I can confirm that these look much better than the equivalent filesize, but the problem is that this is a "community" project, I can't very well expect people to buy (or "get") a professional video editor.

Basically we need a free alternative that works just as well as your recording method/encode method, thought that is very wishful..

Back from much encoding, no recording since I used your file.

First off, the 5 pictures I have included are screenshots of the various CRF rates, they are not in motion, so please do not treat them the same as a video.

Secondly, here is the links to the Five (I have made many more, but this is just for efficiency)

Lastly, I have included my notes here.

I need the public's opinion on what looks good enough, I could just throw 25 in there but I hope 30 is better

As always, video only, the audio is always the same file size so don't worry about it.

Call for volunteers:

0. Japanese-only games with good- h-scenes, I know opinions vary and all, but I have no experience with japanese-only games, so your suggestions are welcome.

1. If you're interested in recording, here are some pre-requisites that will help you make better use of your time spent on the process

1.01: Linux: for now, I have not located a reliable method to direct audio to other (virtual) outputs in Windows, J Audio Connection Kit may or may not work, if you want to help and still want to use windows, I could use the feedback on getting audio separation to work.

1.02: OBS (Multiplatform):

The capability to record a window is an important part of the recording process, it's a shame that winXP isn't supported.

1.03: Virtualbox + winXP

Most visual novels are not complex programs, some of them require d3d, VB does support that if necessary.

So the reasoning behind winXP before W7 is just the resource difference, one takes less RAM than the other, that's all

Well if that hasn't deterred you, you can post in the thread and or come over to #8chH on freenode

I am recording some things myself, but I think if you have a really good computer you can do even much more than I can, like record 16 scenes at once if you wanted to.

In addition, I still need assistance in setting up a torrent, so if you are an expert on that..

why not record your VN's with

simplescreenrecorder ?

It allows you to:

-record audio

-select a certain window to record

-automatically records to webm/ogg/mkv

-its pretty fast

should be in your gnu/linux repos

I haven't tried a virtual box with microshaft windows to test the recording out though

attached is what it can do

SSS is an equivalent option, I find using OBS would have the benefit of a clearer UI when trying to record multiple scenes at once (Via the "scenes" in obs itself) however, I will try as you say for now and do my next tests with SSS w/ webm (on what game? it's a secret to everyone.)

Neither can record multiple things at once without opening them twice which is annoying but whatever.

need feedback on video/audio quality for Test1: Hanabira1

Upload the japanese ones if you like, I'm looking for a 100% completion on english titles, I have to be a bit more selective on japanese though.

SSS doesn't work by the way, it doesn't record a window, only an area.

I really am not the one fit to do this, even though I have the time, I don't have the processor necessary to run 10 virtual boxes at once, and you know, recording 10 scenes at once would save so much time overall, and I can record a measly one.

the WEBMs went fine, around the same size or slightly less in file size, -crf 30 and libvopus b:a 64k Something like 17 minutes for 10MB (the limit over here)

I'll be hanging out in #8chH on freenode when I'm awake

You should really consider using animated PNG for this format. You won't have to deal with the color palette limitations of GIF and you will have smaller file sizes.
