QuickTime format (on Windows)

Xenofex2 wrote on 4/22/2016, 2:38 PM

I regret to acknowledge on this Forum but actual video formats and Codecs is so far a totally alien area for me, and as such, when I do undertake some form of project within MEP. I normally choose to export the movie file in the 'QuickTime' format because it is a name I recognise, and am aware that from past exports, my movies play with no problems (normally) albeit I always use the (free) VLC Program for playback.

As such, a relative video novice I was 'alarmed' to read in my latest Computer Magazine today that "the flaws will never be fixed so uninstall QuickTime now!".It seems that QuickTime contains two serious security flaws within Windows that will never be fixed and that Experts are urging Windows Users to uninstall QuickTime now!

Now I NEVER use the 'QuickTime' Program (as I mention I always use VLC) to actually play movies but now obviously intending to uninstall the actual Program, should I continue to export my completed projects to that format and what happens to those movie files that are on my Computer saved in that Format? Is this also an issue or is just the Program that is the security issue?

Would appreciate any advice.

Hi George

CODEC is short for Compressor Decoder and is a bit of software that performs a defined mathematical analysis of the video data when creating or playing a video file.

The compressor part squeezes the very large amounts of video data into a smaller file size.

The decompressor restores most of the data - most codecs are not lossless - to give a viewable video in a player.

The issue with the QT and its codecs has been known for a while and represent security loophole.

. . . . I normally choose to export the movie file in the 'QuickTime' format . . . .

IMHO the 'standard' format to export in is mp4 - it is the most universal modern format.  Some will argue you should use a lossless format, however the downside of this is the massive file sizes that result..

. . . . . what happens to those movie files that are on my Computer saved in that Format . . . .

VLC has its own codecs for doing the decoding of MOV files and does not depend on QT.

Hi

I do not think MEP will export to .MOV if you do not have the Quicktime player and it's codec installed......?
