As I previously mentioned CRF 18 is virtually lossless; but with higher resolution encodes, you can get away with even higher CRF numbers (and thus lower bitrate).

Fraps source was ~900MB

h264 @ CRF 22 is roughly ~26MB
http://www.megaupload.com/?d=EMJJNB73

h264 @ CRF 28 is roughly ~11MB
http://www.megaupload.com/?d=IFP0NW9F

h264 @ CRF 30 is roughly ~9MB
http://www.megaupload.com/?d=2U28KGF9

All look fine to me, none of these were encoded with "ultra slow HQ" settings that govern the other x264 parameters.
Had they been, compression and quality at the given bitrates could have been improved even further.

Simply select the "High Profile" preset, goto settings, video tab & select "Constant Quality" and move the slider over to where you want.
Go to Audio and reduce the bitrate if you don't need it as high.
Adjust the output size @ anamorphic settings as you see fit under the picture tab, exit the settings window & encode.

If it doesn't work for you; I have no clue why.

CRF 22 is already borderline. And keep in mind, it's not h264, it's x264. Using x264-specific terms (like CRF) and calling it h264 can be very confusing for others

OP, use this: http://www.overclock.net/6852708-post14.html

You can join them with Virtualdub into one large AVI before compressing. Open the first one normally, then File -> Append AVI segment in order. Finally, make sure under Video, Direct stream copy is selected, then Save as AVI. If you do it this way, the joined AVI will not be bigger than all of them combined.

Another option is to create an AVS which joins them, like so:
avisource("file1.avi")+avisource("file2.avi")+.... +avisource("file20.avi") -- etc... then drag and drop that AVS onto the BAT.

I used http://www.ultimate-dvdr.com/media-f...avi-files.html this guide to join my avi files together from fraps,I ended up with a 26Gb file(one lap of the 'Ring in SHIFT=8:20 sec video),Then I used Ripbot264 to convert it down to 668Mb for upload to youtube.

Yeah, I've used it so much, I refer to them interchangeably even though that's not correct

-

h264 = Standard
x264 = h264 Encoder.

To be precise, H.264 is a standard A codec is a package containing both a decoder and an encoder.

That's true too
Though not necessarily containing both; a codec in and of itself really just implies an implementation of said standard in one or both; technically speaking XD

A codec is a device or computer program capable of encoding and/or decoding a digital data stream or signal.
Quote:
a format is a document (the standard), a way of storing data, while a codec is a program (an implementation) which can read or write such files.
That's exactly what I said
An example being the CoreAVC Codec; nothing more than software decoder for h.264 bitstreams.

I think that's just a case of bad semantics. A codec necessarily does both, otherwise it wouldn't be a codec:
Quote:
The word codec is a portmanteau of 'compressor-decompressor' or, more commonly, 'coder-decoder'.

i know a step by step guide on how to compress fraps video with almost no loss of video quality at How to Compress Fraps Videos

It helps to easily compress Fraps video into much smaller file size with almost no loss of video quality as well as convert Fraps video to AVI, MP4, WMV, FLV, MOV, MKV, MPG and more.
