GIMP GAP Green Frames

[mixt]

So I wanted to use pcsx2 to record videos. PCSX2 does a nice job of video capturing into AVI except for a few points where I assume the plug-in is struggling and it duplicates a frame.

I got GAP (GIMP Animation Package) to remove the duplicated frames while remaining in a high image quality. Problem being it won't load it up properly. I can get media players to play it back (albeit with lag) but GAP makes every single frame solid green (008800) such as this. Loading any other video I can find works (including other AVIs), but it doesn't seem to like anything coming from PCSX2.

I'm really at a loss here. I've tried all forms of encryption PCSX2 offers to me (including unencrypted); varying video lengths, sizes, and frame rates; editing extraction options in GAP. I just can't seem to change the result any.

what kind of AVI ? use mediainfo

why not use video editing software like virtualdub ?

if you delete frames, won't that cause a/v desync, or maybe you don't care about audio ?

what kind of AVI

Open DML I think (I haven't dealt with trying to distinguish them past file extension)

Too broad. PCSX2 is a PS2 emulator. What happens is that the video capture application will take frames from the graphics plug-in and save it. This mostly works but if the plug-in is struggling too much then it will resend the same frame until it can continue. So I'm only looking to remove a few frames at a time scattered across the video.

if you delete frames, won't that cause a/v desync, or maybe you don't care about audio ?

The video in question doesn't even have audio. It would take too much time to process and synch both live (since they are exported from different plug-ins).

AVI is just a container. I was more interested in the compression format used

I meant use vdub to delete the duplicate frames, instead of GIMP/GAP

Would YUV be what you're looking for? That and the DML mentioned earlier are the only things MediaInfo tells me that I don't recognize. That or I'm not looking at the right spot in the program. If that still isn't what you're looking for I'll screencap it.

Even looking at vdub now I don't see anything about frame deletion. Basic crops yes, but trying to manually remove a few frames in a 60fps video is annoying, doing that for every few seconds of video every time I export is murder.

I decided on GIMP GAP since it would provide minimal quality loss (since it is a image editor primarily) and I know from working on GIFs it has a very easy method to remove dupes.

ok.. so you're saying automatic dupe detection and removal in gimp gap ? I thought you were manually doing it

you could probably use an avisynth function like dedup or related filters for detection and removal

you could probably use fraps to record audio & video

in mediainfo , if you use view=>text you can copy & paste the text view back here

Worth looking into. I've never used avisynth before. Is there any respectable drop in quality? I'm a bit of a quality fiend.

I'm looking into fraps. It's output files lag things a lot (It is taking WMM an estimated two hours to compile a bit shy of ten minutes of video). I can't judge the flow much yet because of it taking so long. GIMP is struggling to recognize it, giving just the first two frames for now, but that looks like something I can fix with a bit of work.

Your file is uncompressed ; avisynth is a frame server - the final quality depends on what compression you choose. If you choose uncompressed, it will be bit for bit identical

You can choose lossy or lossless compression methods as well , perhaps you wanted smaller filesize, or a format that actually plays well (smoothly) in a media player . Uncompressed video usually isn't meant for smooth playback

Part of the reason you might be lagging and dropping frames (or dupes) might be that you're encountering bottlenecks like HDD I/O . You need a SSD or 2xraid-0 setup to sustain uncompressed 8-bit 4:2:2 YUV . ~1500 megabits/s is ~187 megabytes/s

If you really don't want duplicated frames,
better avoid Windows Movie Maker like the plague.
The Windows Media DMO encoders are too slow,
and unless you have learned the "how-to",
you will get even more duplicated frames.

If you want even better quality use a lossless RGB recording format like FRAPS in lossless mode . The format you're currently recording in has subsampled chroma , so the color edges won't be as crisp

I suspect GIMP probably doesn't handle YUV as well as RGB (most image formats are RGB). The reason it has green frames might have to do with the way the chroma planes are arranged in your particular recording (a different YUV configuration like UYVY might make it play nicer with GIMP GAP)
