I'm still working on a test post for this, but before I even get that far I'd like some help if possible. I'm working on the DS remake for DQ6. Obviously DS games are a pain in the rear end, because of the oddly shaped screenshots no matter what you do, but there are a few issues with this game in particular:

Grab Irfanview, open the Batch resize tool, set the size to 200%, and uncheck the "Use Resample (better quality)" checkbox.

There's also Crop options to get a single DS screen.

Put a fpsnum=60000, fpsden=1001 into your FFVideoSource call, as in:

FFVideoSource("source.mp4", fpsnum=60000, fpsden=1001)

Avisynth itself can't handle dropped frames or framerate changes within a single clip, so you have to tell FFMS2 to handle that.

Also throw a ChangeFPS(30) (or ChangeFPS(30000, 1001) really but whatever) in at the end of the script, I don't think anything in FF13 actually runs at 60 FPS so it's a waste of encoding time and filesize.

E: Audio cuts out before the video does. I don't know exactly how long, but it's about a quarter of a second pretty consistently once it starts desyncing.

Dunno what causes it if it's not what I posted above, but if it's a consistent desync just export the game audio track to Audacity and manually put in a 0.25s silence where it starts.

MP4 is a container. You need to reencode your Lagarith footage to H.264 before uploading it to Youtube or whatever. There are several tools for this available, check the OP.

The culprit is DirectShowSource(). It sucks, do not use it, grab FFMS2 and try again.

Also unless you recorded in like 2560x1440 I wouldn't reduce the resolution like that.

Well, first off, that's a very bad example shot. You're not gonna see differences on a static, mostly black menu screen. You want something with lots of movement.

That said, there's a couple different ways to get a video out of MeGui, which steps are you using exactly? If you use the AutoEncode and don't use the "Use Profile Settings" option then yeah, it'll ignore your encoding settings.

I suspect it's a chroma subsampling issue. Instead of converting the NES movie to Cinepak, convert it to Lagarith and make sure the RGB colorspace is selected in the Lagarith options. Then upscale that to an even integer multiple (2x, 4x, 6x, ...) with Nearest Neighbor.

You might also want to check out some better encoding tools than VirtualDub.

Then convert to uncompressed.

You probably just don't have Lagarith installed though. Do that.

It's an index file. Presumably, you indexed the file before moving it to your external HDD, and the index file still has the full path to the old video location. Either re-index or open up the index file in Notepad++ or something and edit the path.

I think your script scared off everyone else. Here, ask if anything is unclear.

code:

AviSource("F:\Fraps\Movies\FFXIV Sastasha Test (1440x900, 5-14).avi") # <- This loads the AVI file into the invisible "last" variable
v = AviSource("F:\Fraps\Movies\FFXIV Sastasha Test (1440x900, 5-14).avi") # <- This loads the same AVI file into the "v" variable
# Don't load the same file twice like this, it's unnecessary and wastes resources, and in your case leads to unrecognized scripting errors.
v1 = v.Trim(2355, 3114) # <- Trims "v" into a smaller section, stores the result in "v1"
v2 = v.Trim(3115, 23886) ++ ChangeSpeed(Trim(3115, 23886), 9) # <- Here is a big error. 
#    ^ Trims "v" into a smaller section
#                                       ^ Trims "last" into a smaller section
#                           ^ Takes the result from the trim on "last" and changes its speed
#                        ^ Combines the Trim on "v" and the speedchanged trim on "last" into a single clip
#^ And stores the result in "v2"
# The result is a clip that first plays the 3115-23886 part from "v" at normal speed, and then the same part from "last" at 9x speed. Clearly not what you wanted.
# You probably wanted something like: v2 = v.Trim(3115, 23886).ChangeSpeed(9)
v3 = v.Trim(23887, 26904) # This stuff is repeated several times with different trims
v4 = v.Trim(26905, 29415) ++ Changespeed(Trim(26905, 29415), 9)
v5 = v.Trim(29416, 32462)
v6 = v.Trim(32463, 53627) ++ Changespeed(Trim(32463, 53627), 9)
v7 = v.Trim(53628, 57812)
v8 = v.Trim(57813, 63972) ++ Changespeed(Trim(57813, 63972), 9)
v9 = v.Trim(63973, 69892) ++ FadeOut(Trim(69893,70200), 100)
# Here the trimmed section makes sense at lest, but you're still trimming on the "last" clip that probably shouldn't exist in the first place.
aud = WavSource("F:\Fraps\Movies\Born To Be Bone.wav") # Loads a WAV into "aud".
aud = aud.SSRC(v.AudioRate()) # And perform a few operations on it
aud = aud.ConvertAudioToFloat() # though I'm not sure what the point if this one is, but it should work

v2 = v2.AudioDub(aud) # Replace the audio of the intended speedup clips with the WAV file
v4 = v4.AudioDub(aud)
v6 = v6.AudioDub(aud)
v8 = v8.AudioDub(aud)

v = v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9 # combine all videos into a single clip, store it in "v"
# Note that you never do anything with "v" again after this!

Function ChangeSpeed(clip c, float factor) 
{
    return c.TimeStretch(tempo=100 * factor).AssumeFPS(c.FrameRate * factor) \
        .ChangeFPS(c.FrameRate)
}
ConvertToYV12() # Converts the video in "last" -- currently the input AVI file -- to YV12 and stores in "last"
# No explicit return statement anywhere, so Avisynth returns "last". Which in your case is the input video in YV12.

Admiral H. Curtiss: May 11, 2010; I think there are a bunch of people who can create trailing images. I know some who could do this as if they were just going out for a stroll.

Close but not quite. Your final lines of the script are:

code:

v = v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9
ConvertToYV12()

Or, to be more explicit:

code:

v = v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9
last = last.ConvertToYV12()
return last

Which won't do. Change it so that either last gets assigned the video now in v, or return v. Any of the following work.

code:

v = v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9
v = v.ConvertToYV12()
return v

code:

v = v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9
v.ConvertToYV12()

code:

v = v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9
v
ConvertToYV12()

code:

v1 ++ v2 ++ v3 ++ v4 ++ v5 ++ v6 ++ v7 ++ v8 ++ v9
ConvertToYV12()

Technically, if your "different file" guest audio is identical, yes, you could match them up perfectly and subtract one from the other to get a clean game-audio recording.

In practice, this is going to be a lot of trial and error to find the sweet spot in both temporal location and volume. It's probably easier to put your different file guest audio where it is at the moment and add them together to boost it to an audible level.

If you want to try anyway, Audacity doesn't have a direct way to subtract one audio track from another, but if you invert one of the tracks and then add them together that has the same effect.

I think your Trims are wrong, you might have based the frame numbers off the not sped up footage but you're cutting from the fast version here. If Trim tries to trim past the end of a clip it gets the last frame, which would explain why it's showing the same frame in 14 sections.

If you absolutely need to have a pixel perfect recording (you don't), then you can instead capture the raw RGB values, which also means that your video will be larger.

Actually you do, if you're recording at 1x on an old small-resolution sprite-based game. You'll end up with really ugly bleeding across the whole image otherwise.

Last night we recorded ourselves talking over video games and the outcome wasn't stellar. Once I started the actual game recording my audio went fairly staicy. https://www.dropbox.com/s/mbyzrhrt2pj9jhr/DARKpart1.mp3 - for reference. It starts about 1-2 minutes in the actual audio file. I REALLY want to save this audio. Is there anyway I can wizard this to not crappy sounding?

I'm not sure if that's fixable. If you *really* want to save it you could just rerecord yourself, you do have a reference of how you actually sounded at the time after all, but that's probably quite a bit of work.

Though I'm not very well versed in audio editing, maybe wait if someone else has an idea.

So I have a question regarding subtitles. I need to add them to a video, which I can do no problem. The thing is, I'd like to have them fade in and out, and I don't know how (or even if) I can do that in Avisynth. Is it possible, or do I need to use a program like Aegisub to get all fancy?

Create a clip with and keep the one without the subtitles and Dissolve between them. That's probably easy to adapt into a custom function, in fact.

Admiral H. Curtiss: May 11, 2010; I think there are a bunch of people who can create trailing images. I know some who could do this as if they were just going out for a stroll.

It's pretty simple really, the framerates of the three videos you're loading are slightly different. Force the framerate to a common one by doing, for example:

Video = FFVideoSource("F:\Raw footage\Sensors and Emblems.mp4", threads=1, fpsnum=30) +\
FFVideoSource("F:\Raw footage\The last Jammer.mp4", threads=1, fpsnum=30) +\
FFVideoSource("F:\Raw footage\trailer and Act 3 opening.mp4", threads=1, fpsnum=30)

As a sidenote, to prevent possible audio desync, it would be better to load and audiodub each individual video, then splice them together after dubbing the audio, using ++ (or ++\ on multiline statements) rather than what you're doing.

I see the problem but I have no idea how to fix it, because apparently there's no way to switch the delayed expansion state without creating a new scope. Batch scripts are horrible.

Try this but be aware that it could fail horribly when the OCR tool parses anything as having a word enclosed in exclamation points: http://pastebin.com/bwk0hWFC

Alternatively, use the original script and figure out how to set the recursion maximum to something higher than 32, that's puny for today's RAM.

Do note that this issue is supposedly fixed as of version 2.18. Unfortunately, googling for "FFMS2" still brings up the old Google Code page as the first result instead of the new Github page, so many people are not aware that there's versions past 2.17.

FFVideoSource has fpsnum and fpsden parameters to fix variable framerate files, try that maybe. Or the AssumeFPS function.

Do note that, if you still have the first HD PVR, I do not recommend this. The Happauge Capture software has created several half-corrupted recordings for me that would not load in any editing software I tried and had questionable playback behavior in MPC (not seeking properly for example).

Are the resulting video and audio lengths different? Call Info() on the clip directly after loading and compare.

If yes, then that should be easily fixable by just matching those. I had a function somewhere that emulates the old VDub "change framerate to match audio" thing if you want that.
