Quick AVI Creator (QAC) is a FREEWARE, easy to use front-end, which uses several GNU licensed applications to convert video from DVD / MPEG / AVI / DIVX / MKV / MP4 / FLV / F4V / ASF / WMV sources, to AVI / MKV / MP4 containers by using either XviD or x264 video encoders.

Supported up to 2 audio tracks with formats AC3 / DTS / PCM / MPEG / WMA / AAC / OGG either for converting or direct copying according to the provided source and the desired output.

Supported up to 1 subtitle track, either internal DVD / MP4 / MKV subtitles or external text subtitles with formats Subripper (srt), MicroDVD (sub), Sub Station Alpha (ssa / ass) and VobSub ripped subtitles (idx - sub).

The extra goal of the Quick AVI Creator is the absolute tuning of the output. To accomplish this goal, QAC uses AvsP which is the main difference between Quick AVI Creator and other video conversion front-ends.

Therefore you have the full control of the generated Avisynth script, thus you take advantage of every feature that the Avisynth offers. You will be able to preview the output, trim, resize, deinterlace, if necessary, modify the frame rate, or add Avisynth filters (such as denoise).

avi to h264 conversion

  • dvd_to_matrska
  • movie_to_xvid
  • xvid_to_mp4

System Requirements

Obviously a proper decoding filter for decompressing AVI, DivX, XviD, etc. should be installed. Even if you already have one, my suggestion is ffdshow which has been tested and verified that QAC works smoothly with this.

Supported Windows 2000 and above versions. Windows 7 is recommended.

At least a Power User account is required. (Admin account is recommended).

The FLV transcoding feature requires the Microsoft .NET Framework 2.0.

It is recommended to use a modern computer with powerful multi-core processor and sufficient memory.

Attempting to encode video by using older slow machines, you may need ages to complete the task.

Certain programs so called "Internet Security suites", may need to be trained in order to allow certain background activities when QAC launching the several included applications (tools).
