I am using an Avermedia TV Tuner card to capture free to air digital tv in mpeg format. The codec used is morgan streaming and when I load the file into videomagic, it asks if I want to convert the file to an AVI type file. A yes response to this and auto selecting (amoung others) gives an output AVI file with an audio track but NO VIDEO. I have download but not installed the morgan codec. What will I need to do next. Thanks

Video Edit Magic attempts to convert an MPEG 2 file to AVI for better editing. For the conversion to work, you must have a compatiable MPEG 2 decoder installed on your computer. Please install the Morgan codec and then try opening the file with Video Edit Magic.

Loaded the codec and on the first attempt to load the mpg file without converting got a debug error, video edit magic.exe, file 1386\chkesp.c, line 42, The value of esp was not correctly saved across a function call. This is uaually a result of calling a function declared with one calling convention with a function pointed declared with a different calling convention.

On the second try loaded the non converted mpg file with no debug error but, no video details given (should be 1024 x 576, which is the fixed Avermedia setting) and no video dsiplay when viewed. What next?? sounds maybe like a clash of codecs??

Are you using the correct Morgan codec? The ones that we found were Morgan AVI codecs and not MPEG. Can you please tell us the URL of the codec you downloaded?

Try opening the originally recorded file in Windows Media Player and check if you are able to see the video. If you have the correct codec installed then you should be able to see the video.

Plays in windows media player AOK, site used was https://www.morgan-multimedia.com/

The downloaded codec file is m3jpegv3.exe and is Morgan multi media M-Jpeg codec v3.0.0.9

On using GSpot to check video codec found that access to the avermedia avmvdec.ax was incorrect and fixed, but this did not change anything. I am no longer getting the Debug error, but when the unconverted MPG is loaded, not video data is shown and then loading to the time line and playing gives no picture.

I can sent you about a minute of the mpg file is you give me a site to send it

An Update on my last correspondence.

When I play the mpg in media player (which it plays OK) and look at the properties the following were shown.

Video: Intervideo Video Decoder
Video Size: 1024 x 576
Audio: Morgan Stream Switcher

Previous responses may have been msidirected

p.s. But still does not load video into video magic when loaded as an mpg, or converted?

We did some research on Intervideo MPEG decoder and found that these decoders are not completely compatible with the Microsoft(r) DirectShow(r) technology which is required by Video Edit Magic and many other video editors.

If you have a product from Intervideo like WinDVD, you can try to update it to the latest version from their website. This should fix the problem.

Another option is to uninstall Intervideo's decoder and use a different MPEG 2 decoder like the one from Elecard (https://www.elecard.com/ftp/pub/mpeg/decoder/EMpgDec20.zip).

updated the codec as per your first suggestion and yes now I can convert *.mpg files to *.avi, as long as they are less than one minute in length. After that the conversion exe only gives just over a minute of *.avi file.

I can even load over 4GB of mpg file (about 70 minutes) as an unconverted file and it loads OK into the instant preview, which can be played over the whole length, so the whole file is there.

About every second time I do the last step I still get the debug error as before.

Any Suggestions?

MPEG 2 files usually take up a lot of processing power and do not yield themselves to easy editing. For this reason, Video Edit Magic attempts to convert an MPEG 2 file before editing. The Media Converter uses a different method of conversion than the rendering process in Video Edit Magic.

You can try adding the unconverted MPEG 2 file to the timeline and then render it (Make Movie) without editing the file to lower the processing requirements. After the movie is made, create a new project and add this movie for further editing instead of the unconverted MPEG 2 file.
