I believe that the stutters might happen when Fraps switches from one file to another. It creates files up to 4 GB in size (for FAT file system compatibility), and starting a new file is more resource-intensive than normal file writing.
Hmm, I don't believe so. I never made any recording that surpassed 1Gb filesize, plus all my drives are formatted to NTFS.
But either ways, I tried ZDSoft, and I didn't like it (I mean, I didn't try those codecs, but the program itself is too laggy even when saving uncompressed for me).
So I ended up using Fraps, but now the ironic thing is: I never placed Fraps on max recording quality (fullscreen and 60fps), so I tried it, and it worked even better (I know, strange, in 30fps it stutters, at 60fps it doesn't, and UT runs at 85fps normally), as long I didn't have anything else besides firefox an UT running, and it never stuttered. I got full quality, no laggy video clips. But then to actually make the video was an headache: Movie Maker accepted the AVI files, made the entire video, then it wouldn't publish it properlly, then I tried VideoSpin, but it's useless, so then looked for a converter, and I found the most awsome converter of all: it doesn't take much time to convert, and you can keep most quality, so I ended up converting to WMV, using Movie Maker again. Then it wouldn't even publish... had to divide the entire project in 3 different parts, publish each one, rejoin the videos with movie maker again, aplly the music, and publish again.
Now what could be a video of at least 720p, is barelly 480p... :\
Either ways, my preview is done and launched. The quality isn't as good as I desired, but at least it shows somewhat what the pack is and has on it.
Thanks for the help
