I really need help. I have a MPEG1 (VCD) stuff to edit. I know that I have to convert the DAT file to MPEG 1 format to edit. Iâ€™m using Vegas 5. I need to overlay some graphics into the existing clips. My problem is, I lost the quality quiet a bit after render it back as MPEG 1 format (Main Concept codec). Is there anyway to maintain the quality exactly the same as the original while overlaying all of the graphics into it as an MPEG 1 file ? What kind of editing software is suitable for this kind of work ?
MPEG of any normal "profile" is intended for distribution, not editing. You CAN edit it of course, but as you have found the quality losses can be a bit abysmal when you re-compress the video on export.
The workaround is to use software like the Stoik Video Converter
