Make sure your entire set of video tools (codecs, programs) uses the same amount of bits. Probably 32 bit.

There are some serious issues with the recommended YouTube encoding guidelines, especially in recommending all videos be encoded at 720p or over. Here's exactly what's wrong:

Look man, I tested this by uploading several different resolutions and framerates of a few videos and that article is more or less just a collection of my results. If you're convinced it's so wrong, please provide examples to the contrary.

Some things I do want to point out though:

quote:

The section explaining when YouTube encodes to HD is wrong. YouTube will always encode your videos as HD if they have a resolution of 720 vertical pixels or more. Horizontal resolution does not matter.

Maybe I didn't phrase that well, but I meant that HD can be triggered by either horizontal or vertical. 32 x 720 will trigger HD. 1280 x 32 will also trigger HD.

quote:

While YouTube regularly messes with 480p, it doesn't always. Recommending a target of 720p+ isn't always necessary.

Perhaps, but it happens very often, and is especially noticable on things like text. Feel free to try uploading 480p, but in my experience the result will look like poo poo more often than not.

quote:

YouTube does not encode audio in SD videos at 96 kbps.

It did for me. Download my example videos linked and you will see that the SD ones are 96 kbps and the HD ones are 192 kbps.

Also I *really* have to question your advice of using Bilinear resizing, because that will almost certainly result in a blurry mess.

Don't use regular VBA, get VBA-rr or VBA-M.

http://sourceforge.net/projects/vbam/

I'm not sure which one has more solid AVI recording, try both. Using in-emulator recording should remove all PC-related frameskips as well (but not frameskips due to improper emulation or actual in-game lag!).

That said, Mother 3 surprisingly GBA-hardware-intensive, so you may have some minor issues still.

That looks like Composite capture. Composite is old and awful, use S-Video at the very least. Also make sure you properly deinterlace.

That wouldn't help, you need to get a PS2 S-Video cable. Do *not* get a multi-console video cable, as those usually have terrible quality, find a PS2-only one, and read the reviews for the cable.

The PS2's AV out is the same as the PS3 and (I think) PS1 AV out, so if you find a PS3 S-Video cable that should work too.

If you could actually keep Miiverse running in the background it could be considered, but as-is you have to reload the app -- which takes like half a minute! -- every time you want a different screenshot, so yeah, not recommended.

It doesn't scale them particularly well either from what I've seen, gimme a bit and I'll show an example...

Nevermind, looks like the bad scaling is caused by the app/website, the raw screenshots it generates look really nice.

Left is a (I assume) raw capture I grabbed off Giant Bomb, right is my Miiverse post.

I guess you could use this to make LPs, but the half a minute load per screenshot is still a bit much.

Do you need to go to Miiverse? Can you not pull it off of the SD card it saves to?

Except for some rare games like Animal Crossing, this is the only way to take screenshots. You can't actually save the framebuffer to SD or anything, just post it to Miiverse. It's kinda dumb, yes.

So how come capture card makers can't actually design sensible software? I've had my HD PVR (1, regular edition) for a couple years now and originally I used the ArcSoft Total Media Extreme that came with it. Terrible UI design, a nonstandard window that you can't resize, and usually took like two or three tries to actually recognize the PVR. After it was recognized it usually worked fine, unless I turned off the PVR while it was still on, then I had to restart the program to make it work again. And it always crashed after I closed it once I was done. Which, whatever, but still.

Then recently, Hauppauge released a tool of their own, Hauppauge Capture. Great, finally something that's hopefully better. And it is, I guess, but still not great. It's *still* a nonstandard window, but at least you can resize this once, but only diagonally for some reason. It recognizes the PVR better, but the "Record" button is a piece of poo poo and only works half the time I click it, especially when trying to stop a recording. It also outputs TS files that only work in Avisynth/FFMS2 half the time (the other half is "Can't parse file, most likely a transport stream not cut at packet boundaries"), which forces me to remux them. There is a built-in remuxer, but it takes forever and has no batch functionality, and it also reencodes the nice 384kbps AC3 stream into a 128kbps AAC one without telling you. Also I'm stuck with a German version of the program that was obviously not translated by someone actually speaking the language, without any options to change the language as far as I can tell, presumably just because my Windows locale is Austria.

So I guess my long-winded rant-y question is: Is there any actual good recording software for the HD PVR?

For 1), just start some batch processes in either Irfanview (GUI) or ImageMagick (command line).

For 2), I recommend my FaceCopy tool, it has both manual visual copy-and-paste functionality as well as exactly what you want with the batch shorthand replacements.

Mico posted:

FPSnum actually does nothing without FPSden. They're numerator and denominator, FPS is stored as a fraction in video files.

Actually,

the doc posted:

int fpsnum = -1, int fpsden = 1
Controls the framerate of the output; used for VFR to CFR conversions. If fpsnum is less than or equal to zero (the default), the output will contain the same frames that the input did, and the frame rate reported to Avisynth will be set based on the input clip's average frame duration. If fpsnum is greater than zero, FFVideoSource will force a constant frame rate, expressed as a rational number where fpsnum is the numerator and fpsden is the denominator. This may naturally cause FFVideoSource to drop or duplicate frames to achieve the desired frame rate, and the output is not guaranteed to have the same number of frames that the input did.

fpsden has a default of 1, so leaving it out is completely fine if you want an integer as your framerate.

Anyway, the actual question:

Psion posted:

While we're at it, I see fpsnum=30 and I've seen ChangeFPS(30) ... is there a real reason to use one over the other?

Technically, fpsnum=30 lets the source filter handle the conversion while reading the file from disk into the script, while ChangeFPS(30) lets Avisynth handle the conversion after the file has already been loaded. In practice, this makes no difference if your video file has a constant framerate, but makes a big difference when the video file has a variable framerate, since by not providing the parameter Avisynth will assume that all frames in the video have a constant duration -- because Avisynth does not support variable framerates.

When in doubt, use the fpsnum parameter.

Last I checked PCSX2's video recorder makes a file just called "recording" in its own directory, no matter what your AVI filename is, which is the audio. It's pretty stupid.

VDub does. I thought FFMpegSource2() was supposed to load the audio too, but try FFAudioSource() on the same file and AudioDub()ing them together.

Try:

FOR %%G IN (*.raw) DO sox -r 44100 -e unsigned -b 8 -c 1 "%%G" "%%G.wav"

And run the batch file just like that, no dragging/dropping. Might need to rename it to *.bat instead of *.cmd.

Well they're raw, which means they don't have any metadata associated with them, and it's completely up to the playing program to interpret them.

Only because AviSource() told you that it's RGB32 doesn't mean that it actually is -- again, this is a codec decoding issue. Try the version on the site for YV12.

Failure to understand the last variable. What you're doing at the moment is:

last = AudioDub(v, a) # places full video into last variable
last = Dissolve(last.Trim(3374,8558), last.Trim(9328,10642), last.Trim(11926,16118), 60) # replace contents of the last variable with three clips, dissolved into each other
last = last.Trim(17815,31205) # remove the first 17k frames of the remaining video after the dissolve

Fix is either:

AudioDub(v, a)
Dissolve(Trim(3374,8558), Trim(9328,10642), Trim(11926,16118), 60) ++ Trim(17815,31205)

or:

video = AudioDub(v, a)
a = Dissolve(video.Trim(3374,8558), video.Trim(9328,10642), video.Trim(11926,16118), 60)
b = video.Trim(17815,31205)
final = a ++ b
return final

Unfortunately, Irfanview sucks at transparency, so I don't think so. ImageMagick definitely works if you know your way around a command line.

While that may work, I do not recommend needless conversions to RGB and back into YV12, it'll degrade your colors. Once is probably not gonna be noticeable, but for the future, you want to either:
- Record in RGB, do all your edits in RGB, and only convert to YV12 at the end. (less chance to screw up)
- Or record in YV12, edit in YV12. (smaller raw filesize, also not ideal for pixel art stuff)

Try applying Yadif but that does not look like normal interlacing.

I recall there being some tool in maybe Megui (?) that checked a video for possible interlacing and told you which method is the correct one to resolve it, try searching for that if Yadif doesn't help.

Ah, seeing that source video, could you try something? Record another (short) gameplay video, but only start the recording once the game has booted and the PS3 is in "PS2 mode". It might be an issue caused by the switch in video mode when switching from the PS3 OS to the PS2 mode.

Avisynth can not handle multiple video streams with different resolution/framerate/etc within the same file. I believe FFMS2 does have options to override that so you can get the correct "part" of video with the correct settings, but you'd have to check the doc.

e: It might even be as simple as adding a fpsnum=60 parameter to the FFVideoSource call.

Really, though, it all depends on your footage. The only way to really find out is to encode several different quality versions of the same video and find the spot where it gets too artifacted.

Don't change your aspect ratio unless you know what you're doing. If your sole reason for wanting to stretch your footage just to "get rid of those black bars", then for the love of God don't stretch your footage.

That said, hold Shift in Edit Mode to override aspect ratio while dragging the size.

Hey, I've recently had a situation where an SD capture card provided me with 720x480 footage, which made sense to squish to get it back to its intended 4:3 aspect ratio.

But yes, that is a pretty specific use case, which is why I included that bolded part above.
