I don't seem to have Quicktime installed on my WIndows 7 64-bit computer.

Install Quicktime, but create a restore point first..

Hi MusicVid

Huge thanks for looking at my issue with older MP4 video clips. As I have got quite a lot of SVMS older projects that use these Quicktime-dependent clips and also have tons of old MP4 footage that has never been edited yet, then I feel that I must try installing Quicktime as you suggested. However, my concerns are whether doing this could cause any other issues with my 64-bit SVMS12 - for my more recent MP4 footage I am very happy with the way that SVMS12 works and performs.

Therefore, I wonder if I could trouble you for your thoughts on the following before I take the decision as to install Quicktime or not:

1) You mention that I should create a restore point. Is this because you have knowledge that complications are likely if Quicktime is installed on a Windows 7 64-bit system like mine?

2) I remember back in the days of SVMS9 & SVMS11 that you HAD to use a particular version of Quicktime (not necessarily the latest one). Is that still the case?

3) Does the fact that I have a 64-bit Windows 7 PC create further issues - for instance, I am not aware that Quicktime is available in 64-bit version so I presume if I install QT then it will only be 32-bit.

4) Another option - although frankly one that I would rather not have to take, is to convert any of my older MP4 Quicktime clips to another format. I realise this isn't going to help me when I open old projects, but I could substitute the clips I guess. Also, I would want to retain as much quality in the converted clips as I could - without going to the extreme of making them into uncompressed AVIs or similar.

5) I do still have my older versions of Sony Vegas Movie Studio - would installing then on my system work and solve any of these issues with Quicktime MP4s? Bit wary about having two versions of SVMS on my PC but i have heard of others who have done that.

Sorry to dump another load of questions into the pot - but I am trying to weigh up the risks and whether I should just move on an accept a lot of my older footage, projects and clips are now kinda obsolete.

Thanks
Viddy

Quicktime is a system requirement of Vegas.
It's wise to do a restore point, as some QT releases are ...err, unpredictable.
If you choose to try one of the "alternatives," you may also get more than you wished for.
The consequences of not installing QT are that certain image and video formats will not open.
Most people are able to find a QT version that works with their installation.
Unfortunate that this sometimes involves some experimentation; however it is not something Sony has direct control over, nor do other Windows NLE makers.
