MP4Cam2AVI Overview

Introduction:

MP4Cam2AVI is a .MP4|.MOV to .AVI convert & join tool for digital MPEG-4 cameras, such as Sanyo Xacti C1/C4, Pentax Optio MX/MX4, Sony DSC-M1, Olympus C770 Movie, Samsung V40/50/70 etc. Also it supports MJPEG .MOV files from digital photo cameras.

MP4Cam2AVI converts video from .MP4|.MOV to .AVI WITHOUT RECOMPRESSION, that means no quality loss and much faster converson. Audio can be converted to PCM or MP3, or stored 'as is', in source format.

Program should work with .mp4 and .mov files with MPEG-4 Advanced Simple Profile or MJPEG video, and AAC, u-Law or PCM sound.



Features:

MP4Cam2AVI works with both MPEG4 and MJPEG video content. MJPEG is video compression format is most photo cameras.
With MP4Cam2AVI, you can convert & join many .mp4(.mov) files from your MPEG4/MJPEG digital camera to one .avi file, or each .mp4(.mov) file to one .avi file.

For MPEG4 source video, target .avi files can be played like standard DivX movies (with DivX codec), edited with any .avi editing software (i.e. VirtualDub, Adobe Premiere, Pinnacle Studio etc.) or played with hardware DVD-MPEG4 players.

For MJPEG source video, target files can be edited with any .avi editing apps.

Input files:
File type: *.MP4, *.MOV
Video: MPEG4 Advanced Simple Profile, MJPEG
Audio: AAC, PCM, u-Law

Output files:
File types: *.AVI
Video: Source video, NO RECOMPRESSION (MPEG4 or MJPEG)
Audio: Source audio, PCM or MP3



Interface:

Main window:




'file prefix:'

Use it for custom file re-order. When you push 'file prefix' button, selected files are renamed like VCLP****.MP4 -> NN_VCLP****.MP4, where NN - is prefix value (for example 01, 03, etc.). Files are sotred by name, so you cans use prefixes to re-order files.

To remove existing prefixes, set prefix to '' and push 'file prefix:' button.

'preview playlist'

Generates .asx playlist from selected files and opens it in default player. To change player, go to 'settings' tab

'FourCC'

FourCC is a changeable parameter in AVI header, it tells what codec to use for video decompression. You should select FourCC according to MPEG-4 codecs installed on your system (see quick guide for more details). In most cases, default option 'DX50' is acceptable.

When you convert MJPEG files, this option does't matter, FourCC is set to 'MJPG' automatically.

'action'

MP4Cam2AVI has two modes:

1. Many MP4 (MOV) -> One AVI (convert & join)

2. Many MP4 (MOV) -> Many AVI (convert only)

'crop video frames ...'

Check it, if you want crop frames at the end of the file, if audio stream is shorter then video stream. When unchecked, audio silence will be inserted instead of cropping. If some of your files have no audio (Olympus C-770), uncheck this option, otherwise these files will be skipped.

'audio format'

With 'Source audio' option audio is not recompressed, but with AAC input sound target avi files may not be compatible with hardware DVD-MPEG4 players and video editing software, so be careful.

'mono output'

May be useful for Olympus C770 owners. Although it records sound as stereo, it's internal mic is mono. Check this option to downmix channels.

'2 X downsample'

Reduces output sample rate 2 times (i.e. 48000 Hz -> 24000 Hz).

'files with frozen frames'

with some slow or bad SD cards Sanyo C1 video can freeze sometimes, use this option to exclude frozen fragments from target avi file. 'save good fragments > msec [2000]' means that frozen fragment will be excluded, and the remaining part of video sample will be saved, if it is longer than 2000 msec (2 seconds)
