Just wondering, how do you record these videos? I'm trying to record stuff from MAME and would like some ideas on how to do that.

The easiest and fastest way is to use "ADB Tool", by motoschifo, which lets you create videos with a few passages in mp4 and avi, with ease.

You can find it here: http://adb.arcadeitalia.net/download.php

Ignore what AntoPISA said. Just use MAME's built in AVI-writing functionality, -aviwrite.

It will output an uncompressed AVI, so you'll need a good bit of disk space to store the resulting videos, but you won't wind up with source material that's already had shitty compression applied to it, which will be further shitted up by YouTube.

You can also explicitly specify the desired output resolution for the AVI by using -snapsize XxY where X is the width and Y is the height. This can, for example, be used to generate HD-resolution footage that has been upscaled using nearest-neighbor, which preserves crisp pixel edges when uploading to YouTube, whereas uploading a video clip at the game's native resolution will often result in nothing more than 480p viewing being available, and the block-based compression that YouTube uses will absolutely destroy the quality of the video at that size.

Additionally, if you go AntoPISA's route, you'll wind up capturing the bilinear-upscaled output of MAME, and not the raw pixels of the game, and that looks like shit when uploaded to YouTube.

Hi,
my tool is written to simplify the works to make shortplay videos of a game and maximizing the quality (lossless compression, color fidelity).
But that is not the best solution if you need a more specific ingame footage.
If you plan to upload file to Youtube, please remember to make a file at least at full-hd resolution as said by MooglyGuy, otherwise the final quality will be very bad.

MooglyGuy's right if it's a video game. But if it's a non-video system relying on artwork like the LED/VFD games (or my MCU programmers coming in 0.182) you'll need to do it AntoPISA's way.

Except you still don't, doesn't the BGFX backend still provide a way of writing out an uncompressed AVI of the final composited output?

Maybe mame should incorporate dosbox ZMBV lossless video codec.

Is the license compatible? I'd be alright with bringing in just about any lossless video codec as long as the license is compatible.

AFAIK the codec license is the same as dosbox (GPLv2) and most players (vlc, mpc-hc, mplayer) already have support for playing it right out of the box (only windows media player could not play the test videos I downloaded).

How well-supported is it by the common video encoder packs? Let's say I were to eventually (can't right now; contracting gig taking up all my attention) add support for it in MAME, and generated a video with it. Could I upload it directly to YouTube? If not, would I be able to install e.g. the K-Lite Codec Pack or CCCP, and simply chuck it into VirtualDub and reencode it without issue?

Ideally MAME wants to keep core components and OSD level stuff as BSD tho so that it's easy enough to produce a clean BSD-only build for people who want that.

Adding components that are GPL at that level is something, afaik, the team try to avoid.

K-Lite supports zmbv:

That'd be great if you could add it. The format is pretty good for games that don't have a lot of color and it's not very CPU intensive. Hope it can be done!

I indeed could upload an avi in zmbv to youtube:

http://youtu.be/KHje2spv6jQ <--- youtube needed several minutes to process it, dunno why.

and was able to open and view said avi file in virtualdub 1.10.4 x64 running under w8.1 x64. Prior to doing that I downloaded the codec from here http://www.vogons.org/viewtopic.php?p=306810 and installed it using the the included text instructions.

I still can't open it in windows media player (maybe it needs a reboot?) and after installing the codec I can no longer open in mpc-hc O_o; I got the test avis from here:

This is true. However, I think there's an argument to be made for moving the AVI logging itself entirely into the OSD layer, at which point the core license guideline would be moot.

AVI writing seems like something that would be better handled by the OSD layer anyway, since it would allow easier customization of encoders on a per-platform basis.

I'll throw it on the backburner, then, along with moving AVI writing into the OSD layer. Can't really give a timeline, other than MAME is on hold in my life at the moment due to my contracting gig taking up all of my time until at least May/June-ish.

That is cool and good luck in your work.

What you actually want to do is make A/V logging an OSD module, as has been done with audio, video, input, and other sorts of things. The switch would become e.g. -logav avi or -logav x264 or whatever.

As a side comment, avi (just as mp4 or mkv) is a container while x264 (like zmbv or vp9) is a (video) codec.

You knew exactly what I was getting at (I deliberately gave a very sketchy example because I knew Ryan would understand) but you chose to nitpick anyway. See if I actually add that x264 support now.

I didn't even know this was possible with MAME (I should have known better)

I will try next video using this native method. Great !
