"Under 100MB" is a very vague term... because it says nothing about its source.

Where did you get these MKV/OGM files and what are they in terms of resolution, content, and length? What codec do they use? Why do you need them converted to Realmedia?

It's a few lectures of International Space Development Conference (ISDC) that my dad filmed, I don't know whats with him and MKVs files, Whats so special about them? All i know is you can't play them with windows media player.

I want them in real media because I've seen some videos that still looked good and didn't lose to much quality and were under 100mb.

I don't have a big hard drive so I want to save as much space as i can, and I know I can stream real media if i need too. My site http://lunar-tourism.com/ (im stilll working on it)

idk about the resolution but each lecture is between 30-45 mins

All i know is you can't play them with windows media player.Yes you can, install a compliant codec pack like the CCCP (http://www.cccp-project.net/). VLC, Mplayer, and the Core Media Player also have built-in filters that allow you to play it even if the codecs on your system are completely screwed up. But any Directshow-based player, Windows Media Player being one of these, can play MKV files fine as long as the appropriate filters are installed.

MKV is popular for three reasons:

1. It is one of the two major formats that allows H.264 video without ugly hacks and general bugginess.
2. It allows almost any video or audio format. This is quite important as it means you can use AC3 audio from DVDs in it without re-encoding, which MP4, the other major H.264-compliant format, cannot.
3. It has very good subtitle support, making it the format of choice for anime fansubbers.

I want them in real media because I've seen some videos that still looked good and didn't lose to much quality and were under 100mb.The MKVs are almost certainly in H.264, which is superior to RealMedia. You will always lose quality by re-encoding.

ok....i still don't like them, is there away to make them smaller?

300mb per lecture is a bit to much for me

But i do have to say the MKV has very very good video and sound quality but i just really don't have the space....

maybe theres an app i can buy?
I want to make this easy too or atleast has steps thats why im asking for a tut

i don't care if i lose some quality......the cam is on a guy on a stand
but putting subs in isn't a bad idea, sometimes you can't understand them, is there an app so you can make subs and put it in the video?

Pretty much any of the applications in MPEG-4 Enocder GUIs (http://forum.doom9.org/forumdisplay.php?f=78) can recompress them. You'll lose some quality and it'll take a while, but you do what you have to do. Adding subs is a very manual, labor-intensive process, and the best resources for that are anime fansubbing how-tos, the guides for using Aegissub.

Yes, you can recompress them to the same format at a lower bitrate. You'll obviously lose quality, but you can see how low you can get it while the video is still tolerable.

MeGUI is a free application that can do this.

All i know is you can't play them with windows media player.for ogm and mkv and rm you need to install special filters to play those files in wmp

try installing haali media splitter and ffdshow

no need to reencode

To compress a 300MB file to 100MB, the quality must will be sacrificed (perhaps, picture will be much smaller, bitrate will be much lower...).
If you do need to convert to rm/rmvb format, I recommend you winavi video converter (http://www.winavi.com/en/video-converter/video-converter.htm).

Hmm, its an account with 4 posts, of which every single post consisted of promoting a for-pay product that does what free products already do...

hmm... :rolleyes::rolleyes::rolleyes:
