Experiencing a buffering upload problem after completing an update for Magix 15

Hello,

I am the proud owner of Magix 15,17&Pro MX. I've been using Magix 15 for years with much success until just today after I loaded an update to the program. I also have experienced this same issue with my Magix 17 & Pro MX. Here's the issue, I create videos for an internet magazine, and upload the videos to their site. They use a JW open source video player for their video content. When I used Magix 15 before the update the videos uploaded and played perfectly Wanting to use the latest in Magix I purchased 17 & Pro Max over the last few months as I was so pleased with 15, but every time I created a video in either of these versions my videos take to long to buffer to start the video 15-20 seconds and 2 minutes into the video it buffers again for about the same about of time and then lets the video finish. Most of these videos are no longer than 4 minutes in length. When I updated my Magix 15 today, the same problem occurs. So I'm wondering if there wasn't something a codec? within the update that may be causing this buffering issue. Has anyone else had this occur? Is there a way to remove the last update to see if that might actually be the problem? Many thanks for anyones time and response, I realize this is not official support so any response is appreciated. Thank you

What video format are you exporting to and are you using the same settings in 17 and MX as you used in 15?

Are the qouted times to play and buffering based on your Internet connection - has this changed?

Exporting to NTSC 640 x 360 - 29.7- H.264 1720/kbit/s-progressive (MPEG-4), using the same settings in all three programs. The internet connection and speed are the same across all platforms....Thank you for answering

Here's a link to a video using Magix 15

Here's a link to a video using Magix 18 with the same settings on the same website:

As you can see the magix 18 requires a great deal of buffering before it starts playing and the 15 does not.

Magix version 17 responds the same way as version 18.

Many thanks for the links they proved valuable in order to see what was happening.

The problem is caused by a change in the way MEP puts the video metadata into the video file. For streaming mp4 the metadata should be at the beginning of the file, MEP 15 appears to put it at the beginning, whereas 17 and MX put it at the end of the file.

Metadata is information about the contents of the file - in the case of a video file it gives the player information on where the video starts in the file, how long the video is, which codecs to use and other information as needed. When this is at the end of the file, the whole file has to be downloaded before it starts playing.

Fortunately there is a fix for this - you need to download Metadata Mover available here .

I would advise you create a folder specifically for doing this meta data move as it works on all videos in the folder you specify, also work on a copy of the exported file in the folder so you have a backup in the rare event of the Metadata Mover corrupting the file.

Thanx John I will try this. Just to be sure: I should save this program to a folder where I will be saving the exported MP4 file? Or to a file where I will be saving the multitrack session before mixdown/export? And once I do - which it is - when I upload via FTP the completed video to the client's server, I only need to upload the MP3 version?? I assume the little program you provided somehow recodes the MP4 to better arrange the commands? I don't see how that would work, but believe it if I understand this correctly.
