need help, im a newbie in encoding,

what i want to learn is how can i convert/encode a raw video which i recorded using Fraps.. the raw vid from Fraps is really big. i want to re-encode it to HD, altho i dont know much about it, i heard something about H264 and 720p which i also dont know what 720p means.

i have avisynth and MeGUI
please teach me how to encode a raw .avi to a HD .avi using MeGUI

also how much bitrate to make it HD?

Try staxrip if you are a newbie, starting with MeGUI is IMO far too advanced to start out on. Try opening your files (StaxRip will merge them for you) then select x264 and a constant quality preset.

i also dont know what 720p means.

720p means 720 vertical lines of resolution while "p" means progressive, as opposed to interlaced.

also how much bitrate to make it HD?
Entirely subjective, I would advise a CRF value (between 18 and 24, lower being higher quality) rather than bitrate

I think even StaxRip might be more than necessary in this case :)

I'd suggest using Ripbot264. It's very simple!

:search:

Some basics:

H.264 is a video compression standard that is rapidly becoming the new standard for almost all applications. There are numerous implementations of this standard, including x264, Mainconcept, Sony, Apple etc...

Everyone on this board pretty much uses x264, because it's extremely fast compared to the competition and offers superior quality in almost every conceivable case. Also, if's free open source.

A GUI like MeGUI, StaxRip, AutoMKV, or Ripbot264 uses x264 in conjunction with other tools to take an input and convert it to H.264.

There is no such thing as "how much bitrate for HD." HD is anything at a higher resolution than SD: In other words, 1920x1080 (1080p) and 1280x720 (720p) are HD material. You can have a stream that's 1080p with 300 kbps (would be stupid to do that, but it's possible) and it's still legitimate "HD material."

question
can staxrip or ripbot264 add subtitle?

In Staxrip you can, you can hard sub them by adding it as a filter line. Or you can do softsubs ,subs that you can turn on and off, using mkvtoolnix with the merge gui. Just drag and drop the video that you already encoded,then drop the subtitles. Your output will be .mkv.
I recommend Aegisub for subtitle creation.

Also, be sure that the resolution you encode to is AT MOST the same as your source material. Encoding to a higher resolution is pretty much pointless. If your source video isn't HD, then neither should the final encoded video be.
