Video for Windows 1.0:
https://winworldpc.com/product/video-for-windows/1x

Hello, I am trying to encode a video in Microsoft Video 1 using the VIDEDIT editor included with the Video For Windows 1.0 suite. I tried to re-encode the video WNDSURF1.AVI, which is included in the suite. When Video>Compression Options is opened an error message appears, and when pressing continue on this error message the Compression Options menu appears, however the dropdown for Video Compression Method has no options. When you push About on the Compression Options menu, I get another error message. When I close the Compression Options menu, and re-open it, I no longer get the error message, and the Video Compression Method dropdown menu now has 4 options, No Change, Microsoft RLE, Full Frames, and Cinepak. Pushing Configure on the menu with Cinepak video compression option selected shows the configuration menu for Cinepak but if you mess around with the Cinepak menu it shows an error message. The video player in VIDEDIT is able to play back WNDSURF1.AVI and other Microsoft Video 1 samples just fine, as well as RLE samples. Occasionally the ability to compress in RLE will go away as well but I am not sure if that is a feature of the program. I have the same issues using other sample videos other than WNDSURF1.AVI.

VIDEDIT.EXE will let me encode video in RLE but will stop around 40% and say “Cannot write to output file.” It will let me encode MSV1 > Cinepak but the resulting video has major palette errors (most of the colors are purple) and the audio will be very choppy or non existent. It will not let me encode in Microsoft Video 1 at all as there is no option to use the codec in the Video Compression Method menu. When I tried RLE > Cinepak the editor gave and error message and hanged.

Any help would be appreciated. Thanks!
Expected behavior

-Be able to encode video in Microsoft Video 1

-Additionally, if possible, be able to encode properly in Cinepak and RLE formats

Unfortunately I cannot share the sample videos I used, as it does not let me upload .avi files, but you can find many test samples on this disc:

#1492 fixes the audio problem and crashes. For transcoding from video 1 to cinepak video-video format in the videdit menu needs to be set to 16 or 32 bit as it doesn't appear to like 256 color palette bitmaps.

Hi, I apologize for such a late response, I have been very busy lately.

I have tested VIDEDIT now and it does what I want it to do! Thank you so much! I should of specified more in my original posting but I was really trying to re-encode Cinepak compressed videos in 256 color Microsoft Video 1 in order to use them properly on a 286 computer. I am not that concerned about the program not supporting palletization for Cinepak videos because it seems to work for Microsoft Video 1, and you can't use Cinepak on a 286.

I have 2 more questions I'd like to ask:

-I cannot get VIDEDIT to open Indeo videos and I think the codec is installed. ("Unable to open compressor" error.) I saw in another bug report you had a registry fix for a similar issue?

#364

-I am using the Windows Hypervisor Platform hypervisor, whpxvm.dll, with OTVDM. I have an AMD CPU. I am getting normal performance out of VIDEDIT (sometimes better performance on some operations) , but I was wondering if it was possible to speed up the program's operation. Are there any settings I can change in OTVDM.ini or elsewhere to achieve better performance? I was running this program on DOSBox and I liked using the turbo mode feature in order to encode at lightning speed. Is it possible to increase the clock speed of the emulated CPU? VIDEDIT unfortunately is a pretty slow program and I guess that comes with it's age.

Thanks for all your help!

Indeo is shipped with current version of windows but disabled by default probably because of security problem with it. It does work for me with the registry change. That only works for indeo 3.2 though for 4.1 and 5.0 you need
"vidc.iv41"="C:\WINDOWS\syswow64\ir41_32original.dll"
"vidc.iv50"="C:\WINDOWS\syswow64\ir50_32.dll"

Dosbox speeds up the whole machine in way that is impossible for winevdm. The codecs themselves are win32 and run outside the emulation so whpx shouldn't make much of a difference. The only idea I have is that color conversion slows things so use 24bit color.
