HLTV

If you record HLTV demos from a client while logged in as a player all you will get is your first-person perspective in the recording.

If you record while logged in from a client as a spectator then you will record the all players and all perspectives.

In both the above cases, there will be visible aim issues and lag that has nothing to do with reality but is caused by your client and computer and graphics system... IE: you see someone shooting at someone else and that player dies but the shooter doesn't appear to be aiming close enough but blood is squirting nonetheless.

The best quality recordings are made (full map, all players) when recorded directly by the HLTV proxy server running on the same computer as the server itself, commanded to do so directly from the console of the HLTV proxy server.

Slower server computers may not like this and it may cause real lag for the server. The amount of disk space used is also quite extensive ... around 1 megabyte per minute on the average.

Keeping the server (and your client computer too) disk(s) defragged is very important.

Of less quality (but still much better than from a client player) would be to make the recording from the HLTV Proxy server running on some other computer on a LAN or worse still running across the internet (but still much better than from a client).

The farther away from the server you get the less "real" the recording gets, but usually something is better than nothing.

One word of warning though, in HLDM if you start recording demo as a player in the game, you will lose all your current weapons and ammo, sort of an automatic "ok you can record but now die first!" penalty. I'm unsure about other mods.

The autorecord command isn't needed anymore because the record command does it all automatically ... just start a recording and it will create a new recording with the map name and date-sequence for every map until you tell it to stop.

If you want to record just one map then just put in "stop" for client or "stoprecording" for the hltv server in the appropriate config file so when the map changes it will automatically be stopped.

Unfortunately there is no way for HLTV to know how to record just one round (CS, CZ or DOD) so you'll have to do that manually but this works very nicely for recording demos on a per-map basis assuming you have the disk space for it.
