Great software, works well and produces videos that play nicely on Nokia 770 / Mplayer.

Two comments:
- According to what I saw in the profile, it seems you are forcing the frame rate to 25. Why not leave it as source frame rate?
- The target bitrate for video (512 kbps) seems to me a little bit low. I would target 784 kbps.

I will make some tests with various content I have. I very interested to see how you manage video size / aspect ratio transformation.

Hi!
thanks for your reply.

According to what I saw in the profile, it seems you are forcing the frame rate to 25. Why not leave it as source frame rate?
You can remove '-r 25' from the file ini.
If you delete the file ini, the file will be created again with the default settings.
I have forced to 25 because sometimes FFMPEG does not recognize the source frame rate (in some video that i have tested).
In the next version i will add a option to force the destination frame rate to any value or to leave as is.

The target bitrate for video (512 kbps) seems to me a little bit low. I would target 784 kbps
If you make some tests, please let me know :-)

I will make some tests with various content I have. I very interested to see how you manage video size / aspect ratio transformation.
If you are interested, this is the formula that i use:

Width/Height: Source video resolution
dstWidth/dstHeight: Destination video resolution
maxWidth/maxHeight: Max Width/Height destination video resolution (400x240 or 400x224)
VideoRatio = Width/Height

1) - Fit Width
dstWidth = maxWidth
dstHeight = Round((1/VideoRatio) * dstWidth/16)*16 : I use multiples of 16

2) - Fit Height
dstHeight = maxHeight
dstWidth := Round(VideoRatio * dstHeight/16)*16;

3) - Stretch
dstWidth = maxWidth
dstHeight = maxHeight

Then i calc the crop values (multiples of 2) to pass to FFMPEG if dstHeight>maxHeight or dstWidth>maxWidth

I want add a option to force destination VideoRatio (in the next versions).

Great. In general, it is a good idea to avoid modification of the frame rate (can lead to synchro issues) unless you use integer division (1 out of 2 or 1 out of 3 for example)

I already did using mencoder. I convert my daily tv shows in 400x240, original frame rate, 784kbps for video and 192 kbps for audio, and it runs very smoothly.

Maybe an other way to compute the new size would be:
if VideoRatio < 400/240 then fit width else fit height.

This way you do not crop

New Version: N800 Video Converter 0.8.0.3
http://xoomer.alice.it/sepaolo/n800vc/

Whats New:

* You can force Frame Rate and/or Aspect Ratio (or leave the original)
New Frame Rates and Aspect Ratios can be added editing the ini file
* If the Video is cropped, the label 'Auto Crop' becomes RED
* Double Click on text box 'Dest. Dir' opens the Destination Dir in File Manager
* New Layout

The File ZIP contains only the EXE and the INI files, download the version 0.8.0.2 if you need FFMPEG and/or MPLAYER

P.S.: I have tested this setting (in the ini file), Video:784kpbs, Audio: 128kbps,
FFMPEG_ENC=-vcodec xvid -vtag divx -b 784000 -acodec mp3 -ar 44100 -ab 128000
and the video is smooth with MPLayer and Multimedia Player.

Eh Eh! E pensare che ero partito da un file BAT che faceva egregiamente il suo lavoro , comunque ti seguo da tempo su ICHP e sui vari BLOG, e 'a causa tua' ho preso l'N800 :-)

I'm in two minds about this...

Video Convert is an amazingly good program, with a nice and easy to learn user interface (I don't believe in "intuitive" user interfaces), it does its thing without a hitch and produces the output the user wanted.

But...

When a converter produces files that are actually larger than the Divx files it converts, I'm inclined to say: "Thanks, but I need the card space". A 704 MB Divx of "the African Queen" (480x352) topped off at over 1 GB for the N800 converted file (320x240), while VirtualDub gives me a file of around 350 MB for the same resolution. We could go on about the amazing advantages of high bitrates for video and sound, but the simple fact is that I can't see the former and don't really care about the latter.

I wonder if it would be possible, for the simpletons among us, to get an option to set a maximum file size, something I find much more important in a space-deprived mobile media player than home theatre-quality output. Or maybe a box that gives an educated guess of the size for various bitrates. Obviously, that would imply the possibility for the user to change the bitrates...

Do the videos that are converted with this program run well in the build-in medea player?
