Edit First or Convert First for Large File

[marks31191591]

Hi,

• I have a HUGE video file (506GB) -- converted from an old VHS tape from the 1980s. Wedding video 1 hour long.
• Format is MPEG-4 within an MP4 container.
• I load the file into Premiere Elements and it totally chokes -- takes forever to edit. No surpise there.
• Question: if I compress it, will I lose lots of detail? It was originally 720-480 and I upconverted it to 400% in Topaz.
• I need to do scene to scene light correction.
• Edit first (even though it will take forever and most likely crash PE OR compress first and then edit?

When I use an external Grass Valley ADVD-110 to convert VHS to "minimally compressed" AVI it comes through at about 12-13 Gig per hour of video

You have done something really wrong to get 506 Gig for one hour of video... which I suspect is related to saying you "upconverted it to 400% in Topaz" from 720x480 to whatever you have now

You simply can't make good high defination out of the standard definition from a VHS tape

I really don't know how to edit a file like that

Interestingly the 400% upscale video looks amazing. It really does. But it really isn’t editable at that size and I really need to do scene to scene light correction.

How large is the original file without Topaz?
