trakAx

I purchased trakAxPC Pro and I have version 3.0

My OS is Windows 7 64-bit

I was putting together a music video and the video and audio runs perfect in TrakAx but when I go to transcode it to youtube format, audio is still good but video has times where it will be running fine and then it will take one of the parts that will still be a moving video and make it stay there.

What should I do for this issue?

Hi Wes

Thanks for your post and purchasing trakAxPC.

I just have a couple of questions so I can get to bottom of the issue you are having.

1. How does the exported video play in the video output screen when it is previewed in the Media Browser?

2. What media player are you using to play the exported video, Quicktime or VLC player? http://www.videolan.org/vlc/

VLC player is the recommended player for MP4’s.

3. Have you tried and upload the video to YouTube and see if this issue is happening? If you have uploaded the video to YouTube, can you send me a link to it so we can see the issue you are experiencing.

4. What file formats are you trying to mix? WMV, AVI, Mpeg, MP4, Mp3 Etc?

I look forward to hearing from you.

Best regards
Cormac

PC Performance Considerations when mixing or playing multimedia files.

Some performance considerations to be aware of when mixing and playing multimedia files.

Audio and Video creation can involve some heavy duty stress on your PC resources. There are a few factors that you should be aware of from the outset. Your mix may contain many tracks of audio or video or both, which may have time-stretching, effects, transitions, fades, etc, applied. The higher the number of tracks and segments and the greater the number of parameters applied to segments and tracks, the greater the performance hit will be on your computer. The main factors that effect the performance hit when making large complex mixes using large size files are:

CPU speed and whether it is Single, Dual or Quad Core. Usually, the higher the speed the better the performance. Generally, the higher the number of cores the better the performance.

Memory (Random Access Memory). The greater the memory (RAM) size the better. We recommend a minimum of 1GB but for very large complex mixes using large file sizes, 2GB would be most desirable.

Hard Disk Speeds. The higher the drive speed the better. Drive speed of 7,200 rpm upwards is most desirable for large complex mixes.

Hard Disk Buffering. If possible, try to have 16MB of HDD buffer memory available.

The factors that effect playing videos with large frame sizes at high frame rates are the same as those outlined above for large complex mixes. You may experience some stuttering or lip-sync issues when playing large videos with large frame sizes at high frame rates on lower resourced PC’s. If you experience any of these difficulties playing videos, you can convert the files, using trakAxPC’s convertion facility, to a lower frame size and frame rate more appropiate to your PC’s resources.

Some playback problems have been experienced when playing files in Quicktime for Windows. These inconsistences have not been exhibited when playing the same files in Quicktime on Mac computers. If you are experiencing a playing problem in Quicktime for Windows with colour washout or a lip-sync problem, we would recommend that you either play the files in trakAxPC or download one of the more popular media players from the net. The problems referenced above, using Quicktime for Windows, are not normally experienced when using the same files with any of these popular downloadable players. Again, video with high frame sizes at high frame rates may stress your PC which may result in frequent play stuttering and frame freezes or will play the audio out of sync.

I am not sure what your question #1 means that says:

1. How does the exported video play in the video output screen when it is previewed in the Media Browser?

Could you please explain your question back in more detail.

2. The media player I am using is VLC

3. The link to the youtube video is http://www.youtube.com/watch?v=CmoNMIiK8cA

There are some problems throughout the video but especially 40 seconds into the video, it freezes up for like 30-40 seconds

4. They are MP3 & MP4

Thank you for the speedy reply.

Hi Wes

Thanks for sending on the video. I can see what is happening with your video. Thank you.

To explain my first question

In the media browser (the area in the application where you can find media on hard drive http://www.trakax.com/software/wiki/Category:Media_Browser/), when you click on the file you created to preview it, does it play correctly in the video output screen in trakAxPC?

2. Can you tell me what file format and codec of the original file you used is (i.e. the original lord of the rings file )? Is it divx, Xvid. h264 etc?

To find this out, right click on a segment in the Mixing Screen and select properties.(see screeshot)

The properties windows of the original Lord of the Rings file that you edited will appear indicating what audio and video codec the original file was encoded in. (see screenshot)

If it is not too much trouble, could you send me a screenshot of this window so we can see the codecs of the original file? You can upload it to your post and e-mail at .

3. Have you tried to render it more than once. Does this happen every time you try and render it?
Have you tried and render it as a WMV with the same results?

Thanks and I look forward to hearing from you.

Best regards

1# yes i can see it Media Browser

2# h264

3# yes i Have tried to render it more than once i Have tried to it to wma and avf

Hi Wes

Thanks for the update.

If this issue is happening on all three different rendering options, then it seems that there could be an issue or corruption with the original (source) file you used to edit. This should not be happening on both mp4 and WMV as these are two completely different codec and rendering processes.

Would it possible to send me the original (source) file so we could have a look at it and see what is happening.

If it is too big to send, you can use a service like Dropsend, which is free to send to me (again just use my e-mail at .
