Further to my last comment - I've now checked and I don't want their software and driver update managers Sumo and Dumo or their cleaner, but in control panel these appear to have been installed along with the AVI toolbox - ie there's not 4 different programs, just AVI toolbox - so if I wanted the AVI tool I have to keep these other programs I don't want. Not happy KC Softwares and uninstalling the lot!

I installed this via the website directly as advised by Kondoril - brilliant way to avoid the internet security preventing download issue. I installed the lite version, carefully checking I wouldn't get any additional unwanted software - and it said nothing about anything else on the website except the lite installer did not contain any sponsor. Shocked to see it also downloaded KC cleaner, Dumo and Sumo?! The cleaner gives me a clue what that does, but don't even know what these other 2 programs do. I didn't get an option to not select them either, what's going on KC Softwares?
On top of that the program doesn't even appear to work as I can't load an AVI file - I get 'Indice ImageList incorrect', close that popup and says 'check video codecs' and '! Unable to extract frame'. I'm not sure if that's what previous comments are referring to when they say the software is 'useless' and 'would not function', but this file I've tried to load opens in VLC and other programs easily, can't see what issue this AVI toolbox has with it. And I don't know whether to waste my time trying to learn what may be the problem due to the other comments - were they unable to load a file too, try and learn what issue was and still found it wouldn't work? More descriptive comments would be helpful, but anyway I'm not sure I want to waste my time on this when there are plenty of free AVI splitters out there that load files without a problem.

I went out of my way to download, install, and try on two different machines -- one Win 8.1 and one Win 10. I agree with previous comment that this software is fairly useless PLUS this software would not function on either machine!!

Fairly useless. GAOTD has got to up its game and offer better stuff or I'll just stop looking altogether. That is almost the case now.

VirtualDub is the king in the domain of video editing, can do much more, but costs nothing.
A quick look found : Avidemux, Vidiot, Video Edit Master, Jahshaka, OpenShot, Shotcut, and more can be found.
So why should we pay $14.99 for such a simple video editor?

AVI Toolbox, like most all video software, has its limitations -- IMHO the 1st step is establishing what that type of software, & the app itself can & can't do. Typically an old school avi splitter rewrites the avi file you have opened, using the start & end times you set in the program. A decent example might be the free VirtualDub, that works with the avi files common years ago when it was 1st released -- avi files encoded using VFW [Video For Windows] codecs, & that were very often made up of all complete frames. This type of splitter can't do all types of video files, though most types of video can be stuck in an avi container.

Usually the software's web site has a listing of some sort on what file types it can work with, but the only info I saw was the single forum post complaining that [what I assumes was] the full version of the trial had the usually optional software bundled. The biggest limitation I've found personally with splitting or trimming avi files in apps like V/Dub, is that I very rarely have old school avi files to work with. In fact, the only time I've used V/Dub that way in the last several years is when I had to use AviSynth to decode a format like VC1, feeding that to V/Dub [because apps like Vegas won't accept AviSynth as input] & outputting a UT Video intermediate.

That's not to say AVI Toolbox might not be useful to some folks, & if simplicity is your thing, without all the options available in VirtualDub, it has to be simpler to use. Just don't expect it to handle every video file or every format.

RE: the AVI Toolbox feature set...
Taking a screenshot is relatively easy nowadays -- it used to be more difficult when video was always displayed on an overlay layer that the average screen capture software couldn't "see". It became more difficult when NTSC & PAL broadcast video started becoming common on PCs, & then with video DVDs because they used the same standards. The problem is that the standard 720 x 480/576 [NTSC/PAL] video frames aren't shown at that size on a TV at all -- if you watch it as-is the aspect ratio is off. DVD software players stretch the picture to correct the aspect ratio, & I think that's where the trend, started to be able to do a screen capture within the player.

With an app like AVI Toolbox [like most editing capable software] you have to keep an eye on the aspect ratio of the video as displayed. While HDTVs brought the 1080p & 720p frame sizes that are so very common, where what you see is what you get, the old broadcast standard videos are still common too, plus occasionally you might come across anamorphic video, e.g. 1440 x 1080 video that plays at the standard 1920 X 1080. There are also niche apps out there that average several frames in hopes of improving the snapshot or capture of a single frame.

Extracting the audio [sound] track is pretty easy, with the biggest gotcha being that the software needs to understand the video format you've got, e.g. you *probably* won't use the same app to demux [de-multiplex] AVC/H.264 that you'd use for mpg2 [used on video DVDs]. That said, AVI Toolbox should be OK with the file types it handles, & you shouldn't have any trouble finding alternatives at sites like videohelp for whatever other format you've got. Beyond that, once you get that audio track, variable bit rate mp3 audio can be iffy to work with, while AC3 & DTS can be a bear -- DTS because you can't get official software, AC3 because of that & because of its structure. If/when you get into 5.1-7.1 etc., to edit or to save an intermediary you need software capable of waveformatex, or preferred, .w64 [Wave 64], because the latter doesn't have the file size limitations of .wav files [with .wav you often start to run into problems at anything over 2GB, with a hard limit of 4GB].

Splitting [cutting/trimming] &/or joining video is more complicated, so left for last. *Without Re-encoding* you can cut &/or join video only at complete frames. Video files where every frame is a complete picture can be cut & joined anywhere, but they're more rare because the files tend to be huge -- it's far more common for those complete frames to be scattered throughout. *If you Re-encode* editing software can cut &/or join anywhere, plus you can add transitions [e.g. fades] wherever you do it. That's the simple part.

Video files can have different bits of information at the start of the file &/or throughout the file, plus video tracks can be the same format &/or frame size, but have either or both different encoding settings & structures. You can take the same video source, encode it to the same format, using the same settings with 2 different encoders, & get 2 files that are different [incompatible] internally. What that means is that Your Mileage May Vary, capitalized. AVI Toolbox may not do a great job splitting every video file it opens because of that. If at the beginning of the video file it references every frame in that file, if you cut or split it without re-encoding, you may have to repair it afterward, or it may just not ever work, or work perfectly.

If you're using other software capable of joining video files, & want to avoid re-encoding when joining video from different sources, the video needs to match. If you're using software that features smart rendering, which means outputting video only re-encoding the parts that you've changed, the video clips need to match each other, Plus match the encoder that software uses. There are fewer apps that do this sort of thing, many are not free, & many only work with a specific kind of video file.

Installing software can be nasty, having all sorts of side effects, & it can get extremely complicated. Something you often run into working with video like I do from time to time, is that installing software can replace the files you use now to do a certain task. When that happens you can't remove that software entirely, or else you wouldn't be able to do those tasks any longer. Another example would be security software, which often embeds itself in Windows as deeply as possible so that malware can't turn it off.

Soft Organizer, like some uninstall apps, can monitor a software installation, but anything that might cause trouble is avoided. What might cause trouble of course is sometimes hard to say, so they error far to the side of caution. That's not necessarily a problem, but it isn't a full accounting like many, including the Soft Organizer web site, might hint or claim.

If you want to know what the effects are of installing &/or running an app, you take a snapshot before & after, comparing the two. If you want to know more about what it's doing while it's running then look at debuggers etc., though generally the result of comparing snapshots is more practical for more people. You *ideally* don't want much software installed if you go the snapshot route -- if installing an app installs a file that's already present you'll never know about it -- but as not having software tends to make your Windows system useless, that isn't practical unless you perform those snapshots in a VM without much if any software installed, making that VM useful for just such testing, but likely little else.

Note that software like Regshot only creates & compares snapshots, so there are no consequences -- those only come if you start removing the stuff that was recorded -- so unlike software like Soft Organizer, it has no problem at all showing you everything. When you use Regshot it's up to you to save the results, & if you use them to help you remove whatever software, it's up to you to backup as necessary, and as or if necessary, research to make sure just what you can safely get rid of. Depending on the software install you monitored, using the results of those Regshot records or logs can result in a Much More complete uninstall, but at greater risk of problems afterward should you remove something you shouldn't.

I downloaded this 4 different times last night and IT DOES NOT INSTALL!

The download will not proceed any further than the "sharing download" page. I tried Internet Explorer 11 and Firefox. When I tried using GOTD email link I got the message saying "wrong email". It is the same email address and I have used with GOTD for years.

KC4COP

as I suggested in the improvement section, make this work with modern type files, like mp4, mkv and others. I haven't used AVI's for ages now!!

Installed fine on Win 10 64-bit system. Would not recognize my avi files. Button to "check codecs" took me to company web site and offered to let me download another software package. Uninstalled via reboot (in honor of Karl :) ).

Installed ok on win 10 64bit, not sure why the serial number is so ridiculously long, but anyway, tried 4 different .AVI files, non would open, clicked on 'Check Video Codecs' button that appeared, redirects you to a site to download video inspector, installed, ran, identified the needed codec. Clicked on download, this triggered a list of suggestions on google rather than downloading from a database, ran one of the suggestions 'http://www.movavi.com/codec/MJPG.html' this failed, gave up after that. I was looking forward to using the audio extract facility, but as this product relies on external codec sourcing in certain circumstances, this is too much hassle. I'm sure it will work with certain Avi file variations, but not the ones I was looking to work on. Sorry, I didn't want to pen a negative review, I always view positively any submissions on this site, but this one didn't work for me. Keep up the good work GAOTD.

Even the Publisher page do not list a proper features list. for 3 basic fetures I don't get the "and much more"
