Hi,
I just bought SolveigMM Video Splitter 1.1 beta and have been using it to pretty good effect with WMV files. But I have a few questions which hopefully someone can answer.
First, I assume that it does not edit WMV files with what is called 'frame accuracy', but "k frame accuracy'. This leads me to ask what is a K frame?
Second, and following on from this, when I edit WMV files (or any compatible files for that matter) is it best if I edit at the K-frame points or can I just put the file on play and set the markers where I please?
Third. is this product going to be extended to mpeg1 file splitting as well? I would find that pretty useful.
thanks

Hello philebus,
First of all K Frames are Key ones. Video sequence encoded usually consists of groups of pictures (GOP). GOP consists of Key frame (that is first one in GOP) and delta frames. Key frame is encoded independently as a statical picture but delta frames are predicted from K frame and can't be decoded without K frame.
Thus to provide an user fast and a video quality lossless video trimming, the Video Splitter performs trimming tasks with K Frame accuracy.
That means that all output fragments will be started with K frame.

Second, and following on from this, when I edit WMV files (or any compatible files for that matter) is it best if I edit at the K-frame points or can I just put the file on play and set the markers where I please?
Actually for an usability the Video Splitter allow an user to set video positions to K Frames Only. That means that if you select fragments by markers you they already will be started with K Frame.
For now, jointly with Elecard, we are preparing MPEG-2 Frame Accuracy Editing solution that will be added as a feature both to a further version of SolveigMM Video Splitter and Elecard XMuxer.
As for MPEG-1 editing we could take such a feature into consideration but could you describe what do you need it for?

Thanks Dmitry for your quick and very informative reply, and thanks for making such a great product. It sure beats editing WMV files with Microsoft movie maker, or even Ulead Videostudio (which is a good product but useless for WMV).
It would be great to use your product on Mpeg 2 when that becomes available. As for mpeg1 editing, this is not very important for me, except I'd like to edit some music video and flim clips that I have legally downloaded from the net, burn them to a dvd and use them for educative purposes in my work. I realise the quality will not be first class, but if I can edit in a relatively lossless way (as Solveig manages to do with WMV files) then I will not lose too much quality even when I burn them to dvd. And anyway, it would be just for teaching use, not for professional distribution. None of my editing is for commercial use. I am just an interested amateur who stumbled, luckily upon your product through reading the excellent videohelp forums.

Hello Robert,
Thank you for warm words of our software and detailed explanation.
Please let us know if we can be of further assistance.

Is there any possibility in the future to include the "keyboard support" in SolveigMM Video Splitter?
When I say keyboard support, I mean to make use of arrow keys, PageUp\Down... to make selection of frames easier & more accurate...
The true is that by mouse, the accuracy is... simply 0!
Also, is there any way to increase the selection's accuracy down to frame-level?
Where do you think that the new version (that will include these features) will be available? More\less...
-
We are remember that you have already asked as abut this feature
There are no keys for frame-by-frame movement (or at least - if not keys - mouse wheel!). This is a big trouble for me, since I cannot make a down-to-1-frame-specification! This means low precision in cuttings... (my previous software - TMPGEnc XPress - has already this feature - give it a look)
In reality this is not the problem to add frame accuracy navigation.
But as you probably know the Video Splitter performs trimming task with K frame accuracy.
That means whatever frame in a video fragment you navigate an output (trimmed) fragment will be started with a K Frame.
By the way you can navigate by K Frames with Left/Right arrows
The full chortcut schedule is as follows:
Next K frame - Right arrow
Previous K frame - Left arrow
Play/Pause - Space
Set new marker - Ctrl + M
Remove marker - Delete
Clear all markers - Ctrl + C
Select fragment - Ctrl + S
Invert timeline - Ctrl + I
Start splitting process - Ctrl + T
Nevertheless we have got a user feedback that such a frame navigation would be handy even with K frame accuracy trimming.
So do you think so?
Now about a frame accuracy trimming feature. We are going to implement this feature. I suppose it will be added to Video Splitter within one or two months.

In the keyboard shortcuts list, I would add and PageUp\PageDown for many K frames movement (forwards\backwards) or at least a combination (Shift + Arrow)..
I believe that if the next version of Video Splitter makes all these features true & (most of all) keeps the LIGHTNING spees of it, your product will be the best possible AVI editor, simple, fast & just-do-it!
PS: Because I'm a marketing consultant, you might have to "push" your product (SolveigMM Video Splitter) a little bit in advertising in cyberspace, so that everyone will know what it can do & (mostly) how FAST it can do it... Say, "try to find a faster AVI editor... you won't!"

First of all thank you for the promotion suggestion :D
You talk about PageUp / Page Down, you mean upon these calls the program should navigate not to a next K frame but though certain number.
Could you explain from a user point of view a usability of such a feature?
And do you want the part of movie the slider has to jump over should be adjustable?
-
When I talk about PageUp / Page Down, I do mean navigatation though certain number of frames (it would be better to be adjustable in settings\options).
The usability of such feature is obvious, when you need to make cuts in a small range of non-sequencial frames (eg when you need to remove from a clip
the following frames 121-129, 154-185, 253-352, 391-542...)
What do you mean by saying "the part of movie the slider has to jump over should be adjustable" ?
I want to select specific frame start / end for each range & this to be made easy by keyboard shortcuts (not mouse-only).

Ok, thanks for the explanation.
But the ceratain number of frames could be possible to cut or cut off with frame accuracy trimming only.
Neverless what do you think if we add (PageUp / Page Down) keys (not being adjustable first) that will jump to e.g. one tenth of movie length?

I meant the thing you mentioned by yourself :D
(it would be better to be adjustable in settings\options).

Yes master!
In fact that could be a good idea, but the 1/10 can be big (eg for a movie in DivX format of 1,5 hours, this 1/10 means 9 minutes!). 1/20th might be better
(eg of 4-5 minutes in a whole movie).
At all cases though, I INSIST that the main problem of your software (Video Splitter) for the time being, is the non-frame-precision selection (especially without
keyboard). I think that this is your biggest disadvantage for now. The crazy thing is, that (according to my opinion) this feature is easy to be added... Am I
wrong?
Though, I have to say that your biggest advantage of Video Splitter is the process speed. DON'T YOU DARE TO CHANGE THAT! No other similar software
today (shareware or commercial can do that)...
A nice software that you can follow (in GUI & usability fields) is Tsunami MPEG Editor (take a look at
http://tmpgenc.pegasys-inc.com/en/product/tme_feature.html ). I use it for years, but it can do only MPEG format (not AVI). So, I rely on you to make Video
Splitter the "TMPEG Media Editor" of AVI format!
Good luck...

Hello George,
Thank you for your suggestions!
PageUp/Page down feature will be implemented in the next version that should be released within April.
As for "TMPEG Media Editor" we shall necessarily take a look at the probram for investigating its GUI usability.
