Hi,
I was fine with registration, but my final combined video does not appear. It's not in the output file, and I tried by giving it another destination still empty...

How does this program differ from Avidmux?

How do you know that it was registered?
Is there some indication somewhere?

A very simple & straight forward program which does what it claims to do.
This program is for people who are not professional video handlers as it has no complicated tuning parameters, no previous experience in video needed. The output is exactly the same as the input videos.
Loved it and definitely is a keep

Does anyone know anything about the publisher?
It appears to be Xi'an Expand Network Technologies Co, Ltd,

Pobrałam i zarejestrowałam ten fajny program, ale nic nie łączy, mam małe filmiki z przesyłki na Whatsappa. Folder Output jest pusty po skończonej akcji... Buu...Czy Ktoś może mi pomóc rozwiązać ten problem? Mam Windows 10 i mnóstwo programów z Giveaway, a zwłaszcza te do filmów są dla nie cenne..
Pozdrawiam z Krakowa, Krystyna

To the Developer - Thank you for your offering. I see your website offers a portable version (well done - all programs today should be portable!) but I cannot get this registration key to work with it. Can you please give me us a registration key that will work with the portable version.
Thanks and good luck

Yep, just to emphasise what others have said. Add the videos you want to combine, then press 'Combine Videos Now' and a popup appears asking if you want to use the Pro version .. answer yes, and a box appears where you enter the code shown in the readme.txt file.

A very odd registration process where you have to add some files and begin the process of combining before you get a warning that you are using the free version and prompted to update, where you are then presented with a field in order to enter the serial number.

It has CPU acceleration but no GPU, which makes the process slower than it might otherwise be, so an improvement that would help for future versions.

The interface is simple with options for output format, bitrate and screen size, so not hugely customisable.

What I would like to see is an option for the final video to contain optional chapter points that would mark the point between each video.

It probably has limited use and many video editors may do a better job but for a basic add files and press the minimal amount of button job, useful to have in the toolkit.

Simple interface, easy to use. I read the instructions publisher's webpage and had no problems making my test video combo.

I mainly wanted to add a note for others that you won't see where to enter the registration key until you go to make your first video. A box will pop up saying the video will be watermarked unless you register.

How to register? Do not see an option

Doesn't seem to be a registration function- does anyone know if it registers with the provided key in the readme file automatically?

As with the previous giveaway of this last year, this will not function under XP or Vista as installed as it relies upon FFMPEG installed in the data sub folder that was built for Windows 7 or above. When you press the combine videos now button after adding videos to the list it will throw up procedure not found in kernel32.dll errors by ffprobe.exe as the program uses the FFMPEG ffprobe.exe to get the paramaters of each video file to figure out what it can do with them using the rename FFMPEG.EXE file coder.exe
It is possible to replace the windows7 and above builds of ffprobe.exe ffplay.exe and coder.exe/ffmpeg.exe with vista or xp compatible builds if you have them and then it could work under vista and xp too.

If you can get this to run the unlicensed version of FFMPEG on your system you will find it provides no control of the output compression level or codec choice of the output video. e.g. AVI, MP4, MKV, MOV are all video container formats and can contain various codecs for both the video and the audio streams not to forget each codec will have its own compression level controls. We cannot choose what codecs are used or the compression profile that is used. It apears to try and use AVC h264 codec in all containers that can contain such a video stream including those that should NOT have a h264 codec like .mpg which should be an mpeg2 encoded format! And .VOB output type... yup it puts AVC h264 encoded video stream in a DVD specific VOB file.... that will never work if you want to put that on a Video-DVD!

There does not appear to be any way to register this sw nor any directions on how to accomplish this other than the mandate that it be registered.
