Loss of Audio with Transitions in VS Pro X3

[Stuggyduggy]

Have just started using Corel Video Studio Pro X3 on my new desktop PC on Windows7 64 bit. I was previously using on a Windows XP Pro PC without any issues.
When I create a video file with transitions I only get circa 0.25sec of audio after each transition , then silence. If I delete the transitions then I get continuous audio. Have tried various & random transitions but no difference.
I’m starting with files from a Canon camera with the following spec.: Movies: MOV (Image data: H.264, Audio data: Linear PCM) (Stereo. I’ve tried creating files of MPEG2 (720x576, 25FPS, PAL DVD (16:9) & same as project settings but no difference.
Can anybody help?

PC Spec.
CPU: Intel i5-760, Motherboard: Intel DP55KG ATX , Graphics Card: Saphire HD 5770 Vapour X, RAM: 16Gb DDR3 1333, Sound Card: ASUS Xonar Essence STX, Peak Dual DVB-T Digital TV PCI Card, HDDs: Samsung F3 HD103SJ 1TB x2, F4 HD 204UI 2Tb x1, DVD writer: Samsung SH-S222A/BEBE, Akasa AK-ICR-01B Internal Card Reader, Windows 7 64 bit

Have you tried converting to MPEG-2 before editing?

If you can successfully convert to MPEG-2, your odds will be better. (LPCM audio is usually fine, and MPEG-2/LPCM should be OK. There may be something "funny" about the MOV container generated by this camera.)

If Video Studio can't do the conversion, try SUPER (FREE!!!). (If you download SUPER, make sure you are actually downloading SUPER... There website is confusing and there are lots of ads for another A/V converter.)

in timeline view... switch to Audio mode and check to see if the clips are Auto-fading (of sound) during transitions by looking at the rubber bands.

Thanks for the suggestion to convert from MOV to MPEG2 before editing. This eradicated the problem of audio silences after transitions. I used VS ProX3 to do the conversion.
Not a very elegant solution as it involves an additional pre-processing step but I'll explore to see of the conversion can be made more efficient - I'll look at the suggested SUPER software.

Hi Cleveo, I have my project in timeline view but cannot see any option to change to Audio mode. Can you explain in more detail what you mean by switching to Audio mode. Thanks.

Above the timeline is a musical note/waveform icon. That is the Audio View button.

Thanks for the additional direction.
Have checked the output file in Audio mode & the waveform reflects what happens with the audio. That is there is a continuous waveform for the part of the file derived from the first clip, then the wave form straightlines except for short periods at each transition when there is momentary sound.
The project (MSV) file in audio mode shows a continuous waveform except at the transitions where there are gaps
FYI I did not experience this issue when using my previous PC on Win XP which suggests it is not a characteristic of the particular Canon MOV file format.

I’ve now had had time to install & try the Super File converter mentioned by DVDDoug.
Comments
1. As mentioned difficult to find the down load – I gave up & searched using Google & found it on another site
2. The download insisted on installing Real Player as part of the installation - I cancelled all options & subsequently uninstalled this
3. A huge number of options in Super so that I was completely out of my depth. I used MPG as the output container, MPEG-II as the output video codec & MP2 as the output audio codec. The rest I left at the default settings. The outputs were Real Player MOV files about 20 times larger than I started with. There is no clearly labelled option to convert to MPEG2.
4. When the Real Player MOV clips were linked & converted by VS Pro3 into an MPEG2 file this still has the original problem of loss of audio after the first transition
5. Unless someone can advise the settings of Super to use produce MPEG2 files then I’ll stick with the somewhat tedious process of convert clips one at a time to MPEG2 using VS Pro3 before editing.

Have now worked out that if clips from my Canon are first batch converted by VS Pro 3 to AVI files (the option is under file) then these will produce a seamless audio track when combined & output as MPEG2. Be sure to have a backup copy of clips as the original files are overwritten. I believe that the conversion to AVI will not result in a loss of quality. This is a relatively painless method of getting around this problem.
