How To Import 3gp Video?

[EpheMeroN]

I have a Samsung smartphone and I record a lot of videos with it of my kids. I want to be able to edit these videos but hardly any video editor accepts 3gp video.

How can I import these into AviSynth, and export them as AVI files using a lossless codec like Lagarith? I would want the audio decoded to WAV as well so it can be edited alongside the video.

or just re-encode it to ffvhuff/pcm avi with ffmpeg.

Okay that worked. I can import the video now into VirtualDub which will allow me to encode it to lossless. However, the audio is not being decoded? Am I doing something wrong?

Here's my script:

LoadPlugin("C:\Program Files\AviSynth 2.5\Plugins\ffms2.dll")
Import("C:\Program Files\AviSynth 2.5\Plugins\FFMS2.avsi")

FFmpegSource2("C:\Users\User1\Desktop\VID_20110507_105531.3gp")

By default, FFmpegSource2 ignores audio.
You need to add atrack=-1.

Excellent! That worked perfectly.

Now... any suggestions for upscaling / deblocking? I didn't realize how poor of quality 3gp video can be. I'm seeing 352x288 at 14.xx fps with heavy blocking when I try to upscale. I want to eventually upload to YouTube for family to see.

ffmpegsource2 has built in options for quantizer adaptive deblocking. I'm not sure what the proper syntax is, but here is the documentation:
