This software has a serious defect in selecting output bitrate. The minimum seems to be insanely high 5000 bps! Most captured FLV video will use a bitrate of under 1000 bps, so most converted videos will be 10X the size after conversion. Most of that excessive bitrate can't improve quality of the video. It will to be re-transcoded again for any effective use. I haven't contacted Dimo but as it is, I might as well remove the program because the license doesn't permit upgrades to any improved version. IOW - not ready for use yet.

Thank you very much, TK, for your very informative comments, they are utmost helpful and constructive!

(And yes, just like FeMaster states it, once I will have converted a bunch of very old .flv files, there will not be any more need for such a converter.)

The only reason I can see anybody bothering to buy this any longer is to eliminate their antique collection of FLV files. Adobe is killing Flash in just over a year, leaving FLV and all of Flash's constant security holes as just a faded memory; or nightmare, depending upon how you look at things...

Correction: For several files, click on the down arrow in the "Add File" button. But file sizes blown up by factor 20 is really "too much".

Just converts the files 1-by-1, you cannot select several files for conversion which would then be converted one after the other.

That is possible with Wondershare UniConverter which is number one in toptenreviews for converters but has an abysmal converting quality: if the original flv file isn't that good, the converted mp4 target file is unviewable.

Here with Dimo FLV Converter the default target mp4 files (other formats are available, I didn't tried them) isn't better than the original file quality of course, but it is not worse either. I cannot say more precisely but I think the original quality is maintained, perhaps not 100 p.c. but then certainly to a high degree, so this program is MUCH better in this respect than the Wondershare thing.

On the other hand, here are some file sizes for Dimo conversions, flv to mp4: 16 MB > 324 MB, 16 MB > 328 MB, 48 MB > 863 MB.

I know that the target file size in such a conversion is "blown up", but with Wondershare, it's around 2-3 times the original size, here it's systematically by factor 20, and I think that's crazy.

So I would like to hear about other such converters, with good conversion quality (like here) AND acceptable target file size.
