Video Splitter / Aspect ratio problems in Video Splitter
« on: May 20, 2008, 07:01:36 AM »

Firstly thank you for this great little program that does big things extremely well!

But: I'm trimming PAL TV-programs and find that the aspect ratio is wrong in trimmed files. You can see the difference just by looking the resulting video (of course :) ) and from the properties of the file being played. These captures are from Windows Media Player 10.

As you can see, the aspect ratio is not all that is lost, also audio & video codec information is gone too.

I think that this has something to do with the functionality which copies file information (title, description etc.) while trimming, since when I try to trim with earlier version of video trimmer without this function aspect ratio remains correct. I studied this issue little and found out that the aspect ratio can be written in many places in a single video file and they have a certain order where one supercedes another. My suspect is ASF headers, because among other things they have a possibility to choose  non-square pixels unlike many other header types:

I do think that the copying file info is a very useful function but unfortunately in this case it makes the video image look bad. So could you please take a look into this? If no quick solution is no available could you please add option where user can choose if the header information is copied or not?

Thank you in advance!

Video Splitter / How about support for DVR-MS (MCE recording format) also?
« on: December 11, 2007, 05:40:12 PM »
I tried to trim an DVR-MS video file with the Video Splitter 2 without success. The sound was OK but there was no image at all.

Basically the DVR-MS format is MPEG2 video wrapped in ASF format just to get MCE's DRM system working properly, as far as I know. This format is used in every Windows Media Center, including MCE and Vista so it is quite widely used.

Could you please examine if you could include this format to Video Splitter since it would save me a lots of time when cutting recorded TV shows, mainly because I could edit all the files I attend to keep before I convert them to another format. Conversion is obviously faster if I can avoid converting any unnecessary content.

Thanks in advance!

Video Splitter / Video Splitter and file metadata

Hi again,

I think I found a bug, at least this didn't occur earlier. So this is my scenario:

- I record a TV-show with MS Windows Media Center Edition 2005 from DVB tuner.

- I convert this file with PowerCompress to wmv. At this point all of the metadata is present.

- I trim the file with the VideoSplitter and the resulting file lacks (or has wrong) file size and/or aspect ratio metadata.

- I tried manually (and successfully) changing the aspect ratio to 4:3 with this tool:

So I guess this is some sort of metadata problem.

I checked with the WMP10 the files properties and the aspect ratio translates roughly from my language to: real (22:15), showing (4:3).

So my guess is that at some point this metadata (AspectX and AspectY I assume) gets lost leaving the 2.61:1 as aspect ratio, which is wrong for this video. Or maybe the player just calculates this when metadata is missing? I also noted that the audio and video compression data was missing.

I believe that the two different aspect ratios are necessary because in my understanding as in DVD format the DVB specification handles wide screen the same way; image size is actually the same, but widescreen is produced by stretching pixels when played.

I made two files available for comparison, the first one being the direct result of the conversion and the second one is trimmed with VideoSplitter, I just cut few seconds from the end.

You should see the difference at least with WMP10.

Hope this helps to resolve this problem.

Hi again,

I tried to uninstall and then reinstall the application and now it copied all of the fields properly.

So I guess that the problem was me from the beginning, because I installed the new version over the old one without uninstallation at the first time. So some old component may have been left unupdated and that's why it wasn't working properly.

I do some more tests and report if I encounter any problems but for now everything seems to be OK.

Thank you very much, this feature helps me a lot.

Hi, and thanks for taking this task so promptly.

Unfortunately this version you posted did not seem to copy any file metadata when trimming. Furthermore, the shortkey "S" did not seem to work either, but the button in the UI did toggle between keep and cut.

Thanks for your reply.

Great to hear that this feature will be implemented, thank you very much. Hope it doesn't take too long ;)

I've been using Video Splitter for a while now and I'd like to suggest that you add a functionality to transfer all of the source files metadata (name, description, year etc.) to the trimmed one (if user decides so).

I use splitter a lot with files containing metadata and it is frustrating to copy these manyally, since I believe that it would require next to nothing to implement this functionality ;)

So how about it?

Video Splitter / It works now

Just wanted to let everyone to know that the program works now just fine.

Video Splitter / Video Splitter problems
« on: October 09, 2006, 10:56:07 PM »

I recently bought the Video Splitter and two separate problems have arised:

Firstly, when I try to move in the wmv file towards the end using arrow keys and there are black frames in the movie the program slows down dramatically and the processor load rises well above normal, sometimes nearly 100 %. I use the latest updates of Windows and have re-installed all of the WM codecs without luck.

Secondly, when I try to use the batch convert the following problem occurs: I drag-and-drop multiple files to the program thus creating a batch queue. I edit individual files and when trying to start the batch trim only the first one gets converted and the others just get "ran through", meaning that the progress indicator moves really fast through all of the files on the list yet doing nothing.

I've noticed that when opening the .xtl file I can see that the program adds " as_value="00:07:09.49"" parameter to each "track"-object. Removing this from all of the "track" objects seems to solve the problem in most cases. But where does this as_value come from?

Please try to help to fix these problems, because I really like this program and it's user interface.
