We've been doing a lot lately, some stuff will make your jaw drop, but make sure you notice this:

Yep, a lot of good stuff. Rerecording goodness, some DSP-4 fixes, and pf has fixed several things, as well.

Glitch-free SMRPG, anyone?

BTW, did you get that DKC3 bug triaged?

Impressive. ZMVs are becoming more stable and more powerful than I had dreamed...

Post by **Nach** » Wed Apr 06, 2005 12:53 am

So anyone doing anything cool with the new movie support?
Does anyone realize the full extent of what you can now do?

BTW, we're still not done with adding features yet

And did anyone notice that ZMVs are now smaller?

Just curious, is there a limit to the length movies can be (other than disk space)?

I'm wondering because I found some interesting info about movie length/compression that I didn't really know about in the following zip:
http://www.zophar.net/zsnes/zmv/smw33.zip (This zip has a v0.989c ZMV that is a complete walkthrough of Super Mario World.)

4294967295 bytes or frames, which ever comes first.

I just read the zip there.
What he writes simply isn't true.

4 gigabytes? That should be plenty.

I'm not surprised to hear that for some reason.

BTW, I'll post what he said here, for those who don't want the zip:

Super Mario World (U)
---------------------

Recorded on zsnes v0.989c

Note:
-----
You may ask you why I haven't recorded this movie on zsnes v1.36? The answer is simple:
Since the zsnes v1.01 the movie-recorder has been changed and I think it's very sad.
With this new movie-recorder it's just impossible to record movies longer than 10 minutes at least on games like Super Mario World, Secret of Evermore and other big games because the player input will not be recorded exactly after this time. The reason is the compressing method which makes the movie-files smaller. But on a zsnes v0.989c or v0.991 there is no compressing method and you can record as much as you want without changes in the movie.
You can still compress with Win-Zip and its the same then.
I recommend to watch the movie with the version of the zsnes-emulator it has been recorded!

To clarify on the issue.

Right after ZSNES v1.0, zsKnight and _Demo_ started adding internet play.

Prior to that, ZSNES proccessed input, record/playedback movie, did some nonsense with emulation and prints frame to screen, then continue.

With the new internet play code, they put that right after input and some emulation stuff, and this code is/was highly integrated with frame skipping and latency, and they moved the movie code after this.

The main issue here being that frame skip does nonsense before movie proccessing thus screwing up movies.

It has absolutely nothing to do with compressing the data or a ten minute time limit.

The new ZMV code now handles proccessing of movies right after input before all the netplay/latency/frameskip garbage.

Unforunetly though, ZSNES still has netplay and related code spread out all over the place thus causing some strange anomilies if you play with Fast Foward enabled.

Hmm, so ZMVs are supposed to record at less than 1KB/minute, right? Well, I just recorded a brief movie with the latest CVS (with clean install) for ZSNESW and it was about 260KB (the same as 1.42). Am I missing something?

Post by **Nach** » Tue Apr 12, 2005 7:11 pm

Ys, the input is less than 1KB a minute. The ZMV itself contains a ZST too. It's 260KB just for the ZST in small games.

Ack, I don't know why I didn't think of that.

It takes a rather long movie to overcome the overhead of the savestate. I've found this to be true for a long time now.

The savestate data compresses rather well, even with the less advanced algorithms. Solid archiving is awesome on savestates and ZMVs, too. They tend to have a lot of common data, particularly if they're from the same game. Unless it's changed recently, there are also two copies of CGRAM in the savestate: a previous and a current. It becomes rather impressive how eliminating small redundancies ends up in accumulating large amounts of saved space when dealing with a wide breadth of files.

If you look in a MZT directory. You'll see the compressed ZMVs in there are quite tiny.

Not really a relevant thread to post it in, but...

Profile -> Link to Off-site Avatar -> Enter URL

You either need webhosting, or a server that you've setup yourself. Don't try linking to local files (I always get a decent laugh at that); they need to be uploaded to a remote system which successfully accepts HTTP requests for images. Certain free hosts try to block the serving of images to clients where the referrer is off-site. In some cases, like geocities, this was easily bypassed...

This is rather odd.

So, have the problems with Zsnes desyncing playing older ZMVs gone? Will the new ones play any ZMV without desyncing?

Post by **Nach** » Tue Apr 12, 2005 11:26 pm

ZSNES will now play any ZMV without desyncing if the timing used to make the movie and play it back is the same. Meaning same ZSNES version (or a version which matches timings in the areas the game uses), and no trying to change the frame rate.

grinvader and I want to do something about getting ZMV to work right even when you turn on slow down.
