Help with compression.

RevJonG schrieb am 06.09.2006 um 16:01 Uhr

Most of the video I create is used in church services imbedded in PowerPoint. I render the video as uncompressed AVI and then use virtual dub to compress it. Why you ask? Only because I have found the best compression for size, compatibility, and quality when imbedding in PowerPoint is "Microsoft Mpeg-4 video Codec V2". For some reason this is not one of my choices when rendering the video in Vegas. I am hoping someone can tell me how to make it show up as a choice because this would save me one time consuming step…
Thank YOU!

Have you tried when rendering:

- choose filetype .avi
- Click on "custom" button (to the right of the template choice drop-down)
- Select the Video tab
- Look at the drop down menu for video format. I'd expect the codec to show up there. (It doesn't on my machine, but I don't think I have this codec installed).

I have this codec on my PC, but although I can select it from Virtualdub, it does not show up when rendering from Vegas. Very strange.

Hmm... same with me. I didn't know I had this, but if I run Virtualdub I see it.. from Vegas I can't.

Thank you for your reply but alas, It is not there! I wish it were and my hope is someone will be able to tell me how to get it there.

I can not help with that particular codec question.
But what would fit very well inside Powerpoint is any video rendered to wmv - both being Windows natives so to speak. Wmv behaves well in Vegas.

I suspect that the reason it doesn't show up in Vegas is that Vegas is deliberately suppressing the presence of this codec.

To understand the reason for this we need a quick history lesson. Some years ago, before Microsoft finalised its ideas on .ASF (and later .WMV), they were investigating using the principles embodied in the MPEG4 standard for their next generation of video codec and released a series of development versions of this codec (for .AVI), called "Microsoft Mpeg-4 video Codec V1", "...V2", and "...V3". MS made it clear that these codecs were not intended to be used for anything other than test purposes, but because they were able to achieve very good quality at high (for the time) compression rates they were adopted by a lot of the people then interested in video (particularly those in the P&P (porn&piracy) spheres) and they became quite widely used despite Microsoft's wishes. (And if I recall correctly, the original illegal version of DivX was a just hacked version of one of these MS codecs.)

When Microsoft completed the development of this generation of codec they decided that they weren't going to make it available as a codec for .AVI after all, but would instead only incorporate it into their new streaming standard .ASF. They therefore removed the V1, V2 and V3 codecs from download availability on their own sites and put the word out that these were now non-codecs and that anyone else who was making them available for download should also remove them from circulation, and everyone should stop using them. Of course it did not work - once something like that gets established it is impossible to eradicate it completely and the V1, V2 and V3 codecs are still available for download from a variety of places and still in use to some degree even to this day.

Sony as a company tend to operate within the rules Microsoft set out and I suspect that because MS don't want people using these codecs anymore Vegas goes along with that desire and does not list them as available for use even if they are installed on the PC. Less Microsoft-fearing applications like VirtualDub just list everything that is installed on the PC regardless.
