The convert to yv12 is fine. All video you see on the internet, DVD, and television are in YV12 colorspace. The desync might have to do with a change in framerate. The best thing to do is to post your script.

For FFMS just extract the ffms2.dll into your avisynth plugin folder. It should autoload just fine as long as you aren't using 100+ plugins.

So I've got two videos, recorded using the exact same settings and when I look at the file information on both, they both having the exact same frame rate. For some reason though, I get an avisynth error saying that the framerates don't match and for some reason, even when I add in a ChangeFPS command to make both match up, it still says they don't match up. Any ideas what could be causing this and how I could go about fixing it? Here is the script I'm using, sans the ChangeFPS command:

code:

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\ffms-2.17\ffms2.dll")
import("C:\Program Files (x86)\AviSynth 2.5\plugins\ffms-2.17\FFMS2.avsi")
FFMpegSource2("C:\Users\paul\Desktop\DisasterPT4Raw1.mp4", vtrack=-1, atrack=-1, threads=1)++\
FFMpegSource2("C:\Users\paul\Desktop\DisasterPT4Raw2.mp4", vtrack=-1, atrack=-1, threads=1)

audio=WAVsource("E:\BD\Audio\BD-01-mixed.wav")

#Trim into separate clips 
clip1=Trim(source1, 180, 2674)
clip2=Trim(source1, 3216, 12630)
clip3=Trim(source1, 12713, 33586)
clip4=Trim(source2, 1887, 10205)


#Put together using the correct transitions

video0=clip1++BlankClip(clip1, 45)++clip2++BlankClip(clip1, 45)++clip3++clip4++BlankClip(clip1, 75)

video0=video0.Crop(2, 10, -0, -8).Lanczos4Resize(1280, 720).Tweak(cont=1.1).AudioDub(audio).ConvertToYV12()

return video0

It's worth noting that this is the exact same script template that used to work before getting my new computer. Didn't change anything except adding the YV12 thing.

I also must have clicked the wrong link for the FFMS thing, cause I got a whole folder full of files I didn't recognize.

Don't use Selecteven orchangefps ntsc video.

Use this link for ffms2

My capture device records at 60fps (can't change it) and basically just gets duplicate frames. Is there a better way to do it?

I got the FFMS working. I'll switch to it if the concensus is that it's better than DirectShowSource.

MEAT! posted:

Basically what I told Niggurath. If you want 30 fps, just put fpsnum=30 in your ffvideosource call. If you want NTSC, fpsnum=30000, fpsden=1001.

Component is perfectly fine, yes.

The thing is, most devices I've looked at only accept HDMI as input/provide it as output, so I was wondering if there were any decent ones that do component passthrough?

EntranceJew posted:

I would recommend getting a set of splitter wires vs a specialized capture device if you need composite input / output.

Instant Grat posted:

Quick question, say I want to record HD footage from a console, but HDMI isn't really an option, what device should I be looking at? Component is what I was thinking, preferably (the HDMI port on my TV is borked and turns any audio it gets into a horrible garbled mess, which would make recording sessions awful).

I think the Blackmagic Intensity does passthrough, if I recall correctly. Link might still be in the OP.

Tendales posted:

I've got kind of a weirdly specific question: Does anyone know how to force XCOM to use a different audio device? I want to force it to use one of my Virtual Audio Cables.

With most programs, I can just switch the default audio to a VAC line, start the game so that its using that line, then alt-tab out to reset the default audio back to normal. Most games will stay on the VAC line when I do that, but XCOM just happily switches back to my speakers.

There's no in-game option to change audio devices, but I'm hoping there's some .ini setting or something I can change.

I'm looking into the Elgato, but I want to confirm something before I make a decision.

Their website says it comes with a "Component Adapter," but doesn't give any more details on it. Am I correct in thinking it's a little cord that will allow me to plug in component cables and capture HD footage (including audio) from them? I want something with both HDMI and component support, and I want to make sure I won't get stuck without any way to record component input if I get this.

Hey I'm looking for a HD capture card, but I want to play off my computer, does anyone know which ones don't have any delay on PC? I have an HD PVR 2, but because it encodes before sending to my computer I have to use a TV. I've heard the blackmagic intensity doesn't have any delay, is that true, are there any others?

neetengie posted:

El Gato can split the video output to your TV so there's no delay, unless you only have access to one monitor that you need no delay for - in that case, I don't know.

So, ShadowPlay just updated and it now natively supports 1080p recording...
... but it also has a massive audio desync issue now too. Does anyone know of a good way to uniformly fix audio desync? Maybe an Adobe Premiere script or something? Google isn't giving me much and the Adobe sites have been down for some reason.
Alternatively, does anyone know why there isn't audio desync when you record to an external drive? If I could get that to work with my internal drive, that'd be perfect. You see, I'm dreading recording to an ext. drive because the files are split more often, which could crash the game and/or my computer if the splits occur during certain sequences. When you record to an internal drive you get larger files with half as many splits, but since the update all the audio gets desynced unless you use the 'Shadow Record' function, which is not conducive to an actual LP.

Hey, folks. I have a little problem with a game that I'm currently trying to record. So far, I recorded all my stuff with FRAPS at 30fps, and never had trouble. But this game slows down hard when I use 30Fps, and the control input lags a lot. When I just look at the Fps counter without recording, the game ranges from 90 to 100something Fps on average. So I tried recording with 60Fps for an experiment, and while the game ran smooth and without issues, the raw footage was rather choppy when I played it back with the Vlc player.

Nidoking posted:

Have you tried transcoding the 60ish FPS video to a flat 30 FPS and running that through VLC, or encoding a preview video with the same framerate but a lossy codec? 60 FPS with lossless compression is pretty chunky, and not many programs will handle it smoothly. When I work with 720p video in Avisynth, I always have to export in a lossy codec so I can preview it at normal speed. All the edits are the same, frame for frame, so I can throw away the preview version when I export my final video.

The converted AVI plays fine with audio in stuff like VLC media player, but when I try to edit it with an AVS script (I've tried VirtualDub and AvspMod) I get an error 'Error initialising audio stream output size'.

Tin Tim posted:

So here's my follow up on that. When transcoding the 60fps recording to a 30Fps video, I end up with a video that looks like it has constant max payne bullet time, and an audio track that's shorter than the video
