Does the type of computer effect video quality and editing?

No, the computer does not make a difference.

A faster computer will give you a better preview and will render the video more quickly.

The quality is dependent on the camera and the software used for rendering.

What are you utilising to alter the record type? purely changing the extension, till the record type has 2 extensions, and you're changing from one to the different, will consequence in an unusable record. case in point, you could no longer "rename" a vob record to avi. that isn't any longer an avi record, so this gadget beginning it as an avi record (that's what its call says to do) famous rubbish. For an avi record, it somewhat is rubbish. i've got faith that's what you're doing - no longer changing the record to the hot type, purely changing the extension interior the call. detect a conversion application to transform the record from what it somewhat is to what you elect. (seek on unfastened convert onetype anothertype - in spite of the kinds are.) you could discover, in spite of the shown fact that, that your basically options are to pay for a conversion application or to settle for a watermark on the switched over record.
