I think I've asked this before, but does anyone have any alternatives to using Skype screen share? I don't like using Skype for streaming because the audio quality is pretty poor, so I usually use TeamSpeak, but I'd still like to share the screen while streaming.

I am trying to append two AVI files together in Avisynth for editing, one is a raw 20 minute long recording using dxtory, the other is a 2 minute long edit I made in After Effects. Both are lossless AVI files, but they ended up with seperate bit rates so I cannot combine them in Avisynth. Is there a way around this? I tried using

code:

Source1=AviSource("E:\Axiom Verge LP Test\episode1full.avi")
Source2=AviSource("E:\Axiom Verge LP Test\episode1-bosscut.avi")
Return Source1+Source2

but it throws the same error as if I just tried to append them using

code:

AviSource("E:\Axiom Verge LP Test\episode1full.avi") +\
AviSource("E:\Axiom Verge LP Test\episode1-bosscut.avi")

Is there a way around this? I really don't want to spend 2 hours rendering in aftereffects for a complicated 10s video edit.

I am getting the following error in VirtualDubMod

quote:

Avisynth open failure:

ConvertToYV12 doesn't open, gives an error at the bottom of the screen: VideoSourceAVI errorL An unknown error occurred (may be corrupt data). (error code -100)

ConertToYV12 doesn't work on one of the AVI files individually either.

The reason I recommended ConvertToYV12 is that you're going to need to do that at the end anyway when you go to encode the file. I guess ConvertToYV12 doesn't like RGB24 color formats. (So you may need to convert to RGB32 and then YV12.)

If you launch a Steam game and then Alt-Tab to the desktop, you start broadcasting that instead, so it would work. You can also add the other games to the Steam Library through the "Add a Non-Steam Game..." which will also work with broadcasting.

Not strictly related to LP, but you guys are where I learned AviSynth. I agreed to edit some video for a friend, and despite some...annoyances, it's been going relatively well. I stripped out the audio from the clips to edit it all together in audacity, output in WAV format. But for some reason when I try to use AudioDub, it doesn't actually add the audio track. Audio track is in the same folder as the AVS, videos are in subfolders based on which camera it the clip was shot on. I cannot help the fact they are all in a stupid format, with different frame sizes and framerates, thus all the ConvertFPS and Spline64Resize.

code:

clip1 = QTInput("/A kevin/MVI_0001.mov")
clip2 = QTInput("/B penny/MVI_0010.mov")
clip3 = QTInput("/C alex/MVI_1021.mov")

clip5 = QTInput("/A kevin/MVI_0003.mov")
clip6 = QTInput("/B penny/MVI_0011.mov")
audio = WavSource("Dean_Runaway.wav")

clip1 = clip1.Trim(50,356)
clip2 = clip2.Trim(440,652)
clip3 = clip3.Trim(1198,1434)
clip4 = clip4.Trim(450,1315)
clip5 = clip5.Trim(90,300)
clip6 = clip6.Trim(60,498)

clip1 = ConvertFPS(clip1, clip2)
clip2 = clip2.Spline64Resize(1280,720)
clip2 = Tweak(clip2, bright = 30, cont = 1.3)
clip3 = clip3.Spline64Resize(1280,720)
clip3 = convertFPS(clip3, clip2)
clip4 = clip4.Spline64Resize(1280,720)
clip4 = convertFPS(clip4, clip2)
clip5 = convertFPS(clip5, clip2)
clip6 = clip6.Spline64Resize(1280,720)
clip6 = convertFPS(clip6, clip2)
clip6 = Tweak(clip6, sat = .70, maxSat = 75, minSat = 55, bright = 20, cont = 1.2)

I've had that happen as well, where everything looks like audiodub should work, but it somehow refuses. Then I end up replacing the last lines with something like the following, and usually it works, but I hope that someone else might be able to explain why.

end = audiodub(fullclip, audio)
end .ConvertToYV12()

What if you change the end to be like so:

fullclip = Audiodub(fullclip, audio).ConvertToYV12()

AviSynth wiki posted:

ChangeFPS changes the frame rate by deleting or duplicating frames.
...
The filter [ConvertFPS] attempts to convert the frame rate of clip to new_rate without dropping or inserting frames, providing a smooth conversion with results similar to those of standalone converter boxes. The output will have (almost) the same duration as clip, but the number of frames will change proportional to the ratio of target and source frame rates.

The way those were worded made me concerned that if I used ChangeFPS, the new frame rate would mean my cuts would be mistimed due to deleted frames.

Muxing after the video is encoded didn't work (using MeGUI's mp4 muxer), and neither did Fleve's suggestion.

I think I found a much simpler way of sharing audio via skype than fiddling with voicemeeter and virtual audio cable. This should work when sharing screen.

I enabled stereo mix in recording devices, then skype>tools>options>audio settings>microphone>stereo mix

If anyone can try it out and let me know, I'd appreciate it. It seems to work when I'm messing with skype's echotest123 but I can't seem to get my mic loud enough.

Looking at your script, you're making your cuts before doing anything to the frame rate, so that won't make your cuts mistimed.
Remember that your script will be worked through top to bottom, so changing frame rate or stuff after you did your cuts doesn't affect them. If you'd put your cuts after your frame rate changes, that might be different.

ChangeFPS and ConvertFPS both create videos with different frame numbers, the difference is that ChangeFPS doesn't blend frames. Blending frames is bad, you don't want to do it.

I'm not sure what's wrong with your AviSynth script, it should be dubbing in the audio file you specified.

Are you sure the WAV file contains the audio you think it does?

Yes, I can open the WAV file separately and it plays exactly what I expect it to, and it's definitely a 16-bit, 44.1 kHz PCM WAV file.

Are you sure it's actually not getting loaded/dubbed? You didn't accidentally turn off the volume of VDub or something?

The only other thing I can think of is that the WAV file is too big. I've had issues where audio files of several hours wouldn't load entirely with WAVSource() and ended up working around that with NicAudio: https://nicaudio.codeplex.com/ But for me that would still play the start of the audio file, it'd just cut out at some point.

Okay, apparently manual muxing does insert the audio, but for whatever reason Windows Media Player doesn't recognize/play it back, and for some reason it's the damned default player. VLC does handle the audio fine, at least.

Now to go back and retry the audio track because my attempt at noise reduction made things sound shittier than I realized and it's really obviously bad when it's with the video. :negative:

What's the best option/emulator for recording PS1 footage using in-emulator AVI recording?

Mainly to avoid hiccups and the like messing up video, and also so I can abuse fast-forward and have the video come out normal speed (though since the idea's a SSLP it'd be not as big an issue). My computer's beefy enough now that I can handle direct screen recording, but I had bad experiences using FRAPS to record a PS1 LP several years ago that led me to do a lot of editing for some of the videos I posted on it. Using in-emulator recording is generally the best way to get the most accurate video. That said, if screen recording's the best option I'll go that route.

If it's just for pulling screenshots, psxjin is... acceptable.

I mean, you can only use savestates if you manually "save as" each time, and I still haven't figured out what voodoo sorcery is required to get the memory card files from re-initializing each time you boot it, and the audio from the video usually desyncs....

But it does dump video and emulate PS1 games. Usually.

Edit: Dammit, edit tag. :v:

ePSXe is another choice, if you want an emulator that works better. It requires screen recording, though.

I'd love to do videos of FMVs and possibly other stuff too, so audio desync would rule it out.

Does PPSSPP support PS1-to-PSP games and AVI Recording? Because that honestly sounds like a better option than once again diving into the clusterfuck that is PS1 emulation.

e: Looks like it doesn't have AVI recording, so looking like screen capture on whatever PS1 emulator I choose it is.

Well Dxtory might be worth looking into; I just finished an LP of a PS1 game and used that for capturing the video, and there were no noticeable slowdown issues or hiccups. Otherwise I'm not overly familiar with in-emulator recording options for either PSP or PS1 emulators.

midwifecrisis: Jul 5, 2005; oh, have I got some GREAT news for you!

I'm looking for feedback on GeForce Experience ShadowPlay as a way of recording. I guess you can't specify codecs with it but it records in H.264. I played around with FRAPS and DxTory and wasn't satisfied because of the performance hits - ShadowPlay had no slowdown. It also has the ability to stream from your mic but I'm most likely going to cut out redundant parts of the video and then record in post, probably with a co-commentator.

So far I can't really find any reason NOT to use it - is there anything that I might not be factoring into the equation, as a first time LPer?

# ? Jul 3, 2015 21:54

Xenoveritas: May 9, 2010; Dinosaur Gum

How do you intend to edit/encode your final videos?

ShadowPlay can have issues. Generally it works fairly well. The reason it doesn't add any real slowdown and the reason you always end up with a lossy H.264 file are because newer Nvidia cards (600+, I think) all contain dedicated H.264 encoding hardware to allow the Nvidia card to stream to that Nvidia Shield device you've surely got. (I mean, everyone has an Nvidia Shield, right?) They realized that they could use the same technology to instead save to your disk.

The caveats I'm aware of are:

If you're using Logitech hardware, be warned that ShadowPlay does not play well with the Logitech Gaming Software. I don't know if that only applies if you're using a Logitech headset (I'd assume so) but if you are, you're going to want to kill the Logitech Gaming Software while recording. Otherwise you risk the audio cutting out.
If you're editing with AviSynth, FFMpegSource has issues with files generated by ShadowPlay (specifically, audio desync). You can work around them with FFMpeg.

Beyond that it's been working for me.

# ? Jul 3, 2015 22:15

midwifecrisis: Jul 5, 2005; oh, have I got some GREAT news for you!

I'll be using Adobe Premiere for the video and Audacity for the commentary afterwards. The only Logitech hardware I have is a mouse, but I'll be on the lookout for any audio issues just in case since it does have software.

How detrimental will that loss be if I encode with Lagarith in the final product? Are there alternative light-weight programs for recording that'll still let me choose another codec?

It's kind of annoying because my computer is pretty decent, (i7 5820k, 16gb of RAM with a 750Ti) but even on a game from 2012 that slowdown still creeps through. Maybe I'm being overly sensitive though, the frame rate doesn't go below 30. Usually 35-45.
