Please help codec issue

[johnfranki]

Hello, for some time know I would record video game footage on my computer using emulators. These programs use certain codecs to compress video and such. Forever now I have used Microsoft video 1 for a codec, but all of a sudden when I would compress videos it makes the video change blue and alternate colors around which isn't good. Anyone with codec experiences or advice on how to fix this issue, I would greatly appreciate because I have searched for 3 days now, and if my question is a tad vague I will clarify.

MS Video 1 is extremely old, slow and doesn't compress well. It sounds like the software is using VFW codecs -- you could try HuffYUV for lossless realtime encoding. You would want to compress that more later on. Some other possibilities are PicVideo MJPEG and Divx. Xvid may work too but it's a little slower. ffdshow includes several VFW encoders.

I would download and install HuffYUV first because it's free and simple. If the software allows you to use HuffYUV it should allow you to use other VFW encoders.

What emulator are you using?

[Cornucopia]

It's very likely that MS Video1 uses some DLLs which have dependencies based on older versions of Directshow, VFW, etc. It's also very likely that your machine has since been updated beyond the point at which those dependencies have been broken.

Best way around this is to create a "clean sandbox" using a custom-made Virtual Machine, with OS, DS/VFW, and all other apps and features working in the correct era for the codec (both encoding and playback) and for the game emulator.

I have sownloaded ffdshow codec, and it is working beautifully I get full frames and great quality, thank you so much dude. And as far as emulators I use nestopia,snes9x, and vgba. Thanks again you saved my can.

Hello Jonh,

I also record videos from emulators.

Already lost many time looking for best codec.

Now I can share my find.

Use camstudio codec. He's not have colors problem entioned and works on any Windows and any emulator with AVIout

Any questions, reply

I use nestopia,snes9x, and vgba

Thanks. Do they have the recording ability built in or are you using a screen capture utility like CamStudio?

Both have AVIout engine.

I have used ffdshow codec to record a well recording and am finding some slight audio lag about 7 minutes and when many things are on the screen, in is ffdshow made for this? Edit tried camstudio and is working a tad better so deli ma solved I suppose thanks guys.

What endoder did you use in ffdshow? If you use one that is too CPU intensive you will likely get dropped frames which can cause A/V sync problems.

Very strange. Because I record many videos on nestopia and never get desync.

After record, open in VDub and play. If correct sync, this problem is on the players (very normal).

Try record with HUFFYUV (included in Klite Megapack Version). Bigger files but 60fps record no frames on C2D E4500 at 640x480.

Tell us after this.

Do not install Klite Megapack unless you want to screw up your system. ffdshow includes a HuffYUV encoder. Its MJPEG encoder should be pretty fast too. There's a standalone version of HuffYUV that's multithreaded. Its significantly faster than the old single threaded version if you have a multicore CPU.

Never had problems with the Klite. Use since 2005.

Just I posted it already contains all necessary codecs to encoder files.

Tks for Huffyuv MT. I will test tomorrow.

I actual discovered that there is nothing wrong with, either the camstudio or ffdshow codecs when recording on the emulators, but this is just a desync problem that can be fixed with virtual dub. However when I try to compress it says I don't have the two compression codecs that I have, mpeg layer 3 for audio and ffdshow for video, stumped again.

[jagabo]

I'm not sure what your saying but...

There are two audio systems and two video systems in Windows: Directshow and ACM (Audio Compression Manager), and DirectShow and VFW (Video For Windows). Some programs use one system, some use the other. Each system has its own codecs. ACM and VFW are old and deprecated (though still supported) by Microsoft. Programs written for one system cannot use the other system's codecs. Most media players use DirectShow for both audio and video. Many video editors, including VirtualDub, use VFW and ACM.

Also, it's possible for a codec to have the ability to encode (compress) but not decode (decompress), or vice versa.

ffdshow has separate configuration dialogs its DirectShow and VFW codecs. Be sure you have the video codecs you are using enabled in both sections. Start -> All Programs -> ffdshow -> VFW Configuration, and Start -> All Programs -> ffdshow -> Video Decoder Configuration (DirectShow).

You can use LAME ACM for MP3 encoding and decoding in VirtualDub.
