Avi Converter - 24, 25, 30 fps option ?

[producer]

How to change the settings in Avi Converter so that to get a video with 24, 25 or 30fps instead of 20 and 22 fps only? It is very important to be!
Any ideas?

There is a hidden file called Converter.ini in the installationfolder of AVI Converter (mostly installed into c:\programs\aviconverter). Unhide this Converter.ini and edit it with the program Notepad.
Inside of Converter.ini you will find -ofps 20 for example. This is the value of the pregiven framerate: 20fps

A better program to use is viDrop, you will find it under Downloads/Tools.

At least a little note: Not all possible framerates will be accepted by your MP4-Player. I've seen Rockchip-Player with 15,18,20,22 or 24fps untill know.

Thank you for the help! Actually, I tried viDrop many times, and whatever settings I put, the result is 1 second or more difference between video and audio. Keep in mind that I am audio-video software spe******t and production maker! So, the viDrop is the fault!!!

The real encoding engine behind viDrop and AVIConverter is the programm MEncoder - its a freeware with a bunch of options. Some people are getting Audio & Video synchronized by using the option -speed, others prefer the option -delay. Please do a little search about MEncoder and his options and use them as "Extra MEncoder Options" in viDrop: it's much easier to use instead of patching the Converter.ini.

Would you tell me more about where and how to set -speed and -delay in AviConverter, please?
Also, Can somebody tell me the meaning of every parameter here, especialy the red-colored ones:

1-3-1=-ofps 24 -vf-add scale=320:240 -vf-add expand=320:240:-1:-1:1 -srate 44100 -ovc xvid -xvidencopts bitrate=320:max_bframes=0:quant_type=h263:me_quali ty=6 -oac lavc -lavcopts acodec=mp2:abitrate=192
1-3-2=-ofps 24 -vf-add scale=320:240 -vf-add expand=320:240:-1:-1:1 -srate 44100 -ovc xvid -xvidencopts bitrate=320:max_bframes=0:quant_type=h263:me_quali ty=6 -oac lavc -lavcopts acodec=mp2:abitrate=192
1-3-3=-ofps 24 -vf-add scale=320:180 -vf-add expand=320:240:-1:-1:1 -srate 44100 -ovc xvid -xvidencopts bitrate=320:max_bframes=0:quant_type=h263:me_quali ty=6 -oac lavc -lavcopts acodec=mp2:abitrate=192

Want to say in addition that no matter what level of video and audio bitrate I put, my Mini MP4 Player opens it and plays it without any problem. The only problem is when I put framerate value different than 20fps, the delay between audio and video is terrible - more than 2-3 seconds.
So, which parameter to adjust so that to keep in sync audio and video depending on framerate changing???

[lca77]

Please try this values first:

-ofps 20 -vf-add scale=320:240 -vf-add expand=320:240:-1:-1:1 -srate 44100 -ovc xvid -xvidencopts bitrate=350:max_bframes=0:quant_type=h263:me_quali ty=4 -oac lavc -lavcopts acodec=mp2:abitrate=128

How to build in the delay option:

-ofps 20 -delay -0.2 -vf-add scale=...

And how to build in the speed option:

-speed 0.96 -ofps 20 -vf-add scale=...

At least a little extract of www.mplayer.hu's documentation to expand:

expand=w : h : x : y : o : a : r

Expands (not scales) movie resolution to the given value and places the unscaled original at coordinates x, y. Can be used for placing subtitles/OSD in the resulting black bands.

<w>,<h>

Expanded width,height (default: original width,height). Negative values for w and h are treated as offsets to the original size.

EXAMPLE:

expand=0:−50:0:0

Adds a 50 pixel border to the bottom of the picture.

<x>,<y>

position of original image on the expanded image (default: center)

<o>

OSD/subtitle rendering

0: disable (default)
1: enable

<a>

Expands to fit an aspect instead of a resolution (default: 0).

EXAMPLE:

expand=800:::::4/3

Expands to 800x600, unless the source is higher resolution, in which case it expands to fill a 4/3 aspect.

<r>

Rounds up to make both width and height divisible by <r> (default: 1).

Thank you once again for the info!
As I said before, I have no any problems with my player, even with 512+ kbps video and 192+kbps audio. The ONLY problem is when I change the framerate!!! Actually, when I forward or rewind during playback, the videoclip plays ok, but after a second or two the delay becomes again so big. So the player reads the data rightly, no matter from which frame I will start it. But the delay is always appeared because of framerate. If I keep the framerate always 20fps - no any delay. Weird...
