|} | |||
This article has been written around 2008 when emulating games in MAME was way more difficult as it is today in {{CURRENTYEAR}}. Emulating games at that time required a lot of CPU and there often was simply not enough performance left for capturing said games without loosing frames in the process. Both MAME and the conventional capture systems used were prone to frameskips. This article -at that time- tried to mitigate these issues by showing an alternative capture method (albeit more complex). | |||

You will find your mng file inside the '''snap''' folder and the wave inside the '''root folder''' of your mame(where the mame exe is).

*For all other odd numbers (like 59 if you capture cps2) select the third option and chose: '''change so video and audio durations match''' like in the screenshot shown below. Note that my screenshot shows a 59.634 framerate. This is absolutley ok because if you visit [http://www.mameworld.net/maws/romset/ssf2xj the mame database maws] and scroll down to frequency you will notice: The game runs at 59.633333Hz. This is not an error. The game really runs at that frequency. A lot older games have such strange frequencies. | *For all other odd numbers (like 59 if you capture cps2) select the third option and chose: '''change so video and audio durations match''' like in the screenshot shown below.

== | == Capturing with aviwrite (new & easy method) == | ||
This method follows a different new approach. Newer mame versions support a avi writing method to ease up things. Please take a look at these two sections before you read on. They explain the commandline structure and how to write own batch scripts for recording. | |||

:[[Mame_Video_Capturing#Writing_your_own_batch_file_and_recording]] | |||
Instead of using this line([[Mame_Video_Capturing#Introduction: | from above example]): | |||
<code>MameUI32.exe ssf2t -pb ssf2t.inp -mngwrite ssf2t.mng -wavwrite ssf2t.wav</code> | |||
you have to change it into: | |||
<code>MameUI32.exe ssf2t -pb ssf2t.inp -aviwrite ssf2t.avi</code> | |||
The resulting file will be saved in your snap folder. It wil contain sound so there is no need to write a wave file inside the command line. This method is very easy to use. | |||
= Postproduction = | |||
You can do additional work like resize the video, add some filter and do other editing. Remember: Uncompressed video files are very large! Try a lossless codec like lagarith to preserve quality for further editing. Select file and then Save as AVI to save your footage. | |||
If your framerate was 60 you are done. This is probably what you wanted in the first place Sit back and enjoy your crisp, fluid 60fps video footage. If your framerate was odd ( like 59.634 for CPS2 games ) then adjust it to match 60fps. Trust me you will not notice the difference between 59.634 and 60. | |||
