I've purchased QuickTime 7 Pro to edit some movie files, and avoid having to import/export them to iMovie (which takes too long).

 

Having read the help pages, I think I understand the concept of how it works, however I can't seem to edit the movies.

 

I'm looking to define an "in" and "out" point with the playhead but the playhead won't split - what might I be doing wrong?

 

Thank you

    place playhead where you want an in point then press   I  on keyboard

    place playhead where you want an out point then press   O  on keyboard

    to trim the clip down;   Edit  > Trim to selection

    Thanks - is there a way for the in/out points to be visible on the timeline at the bottom?

  • Jerry Dammers Level 1 Level 1 (0 points)

    My files are 3 hour videos - this is specifically what I want to do:

     

    1. Remove start/end segments of the file

     

    Ideally, I just want to delete the segements I don't need from the start and finish, and then resave the file.  Having read the Help section, I think that i will need to save the edited version as a new file - is that correct?

     

    If so, that will consume quite a bit of space, as they are large files.  If I delete the original file, will the quality of the new file be any less than the orginal?

     

    2. Edit/copy segments into new files

     

    This is where I want to lift segments of the file and create a new file.  To do this I was expecting to see the "in" and "out" markers in the timeline but when I press "i" and "o", nothing shows in the timeline (which makes it difficult to track) - is there a different method to pressing "i" and "o" to edit segments?

     

    Thank you

    Use the "Display" window to actually select the "in" and "out" points. (I.e., scrub the playhead to the approximate location you want and then use the left or right arrow keys to move the playback head forwrds or nackwards one frame at a time. Mark the frame you want and repeat this operation to mark the other end of the file segment to which you wish to trim the file to or to mark the segment of the file you wish to remove.)

    yes save it as a new file

    Do not delete the original file. Move it to a backup drive or optical disc, but do not throw a way any original.

    If you;    save as > self contained     it will have exactly the same quality of the original

    Thank you 

     

    You will see the in, out and play head positions you have made as below:

    Once you perform the trim function the 3 markers will reset

    Yes. The easiest approach here is the simply make the first frame you want to keep as the "in" point and the last frame you want to keep as the "out" point. Then select the "Trim to Selection" option under the Edit Menu. Then select the "Save As..." File menu option to save the selected segment to a new MOV file container which you can then rename to best identify the particular segment.

     

    Alternatively, you can mark the segement you wish to keep as above but instead select the "Copy" Edit Menu option to save the reference pointers to memory, open a "New" player under the File Menu, select/activate the new "Untitled" player, paste the copied segment to the new player using the "Command-V" keyboard shortcut, and the use either the "Save" or "Save As" option to save the new "Untitled" player as a named file.

     

    Always try to keep 15-20% of you drive (or at least twice the source file(s) size space) free before attempting an edit. One way to cut editing space requirements is to to save the "new" file as a "Reference" file. However, this means you cannot delete the source file until such time as you finish editing the the reference file, have exported the edited file to a target compression format depending on its final use or method of distribution and have determing that no further edits are required form this source EVER.

     

    If you use the "Save As..." option to create a new "Reference" or "Standalone" file, then the quality is the same as your source file. (I.e., this option copies the segment you want to a new MOV file container in its original compression format. On the other hand, if you export the file segment to a different compression format, then its quality will depend on the specific codec(s) and settings used for the export.

     

     

    2. Edit/copy segments into new files

     

    This is where I want to lift segments of the file and create a new file.  To do this I was expecting to see the "in" and "out" markers in the timeline but when I press "i" and "o", nothing shows in the timeline (which makes it difficult to track) - is there a different method to pressing "i" and "o" to edit segments?

    The basic process for "lifting" one or more segments from a source file and saving them as independent files was explained above. If not "in" or "out" points are being displayed in the timeline, then your source file probably contains a "muxed" audio/video stream of data. (I.e., the setting of QT 7 Pro "in" and "out" points is content adaptive and may not be available for certain media. In these cases you will probably be better off using the free MPEG Streamclip" app which works essentially the same as QT 7 Pro but better supports "muxed" and/or transport stream media but does not support the QT 7 Pro compositing features.)

    Thanks to you both for your help.

     

    Having read youtr response, it became apparent the issue was that the files I was having problems with were mpg files (transferred from Betamax to a Windows PC, then transferred to my MacBook Pro via a portable hard drive) - hence I can't seem to edit them.

     

    The mov files (VHS direct to my MacBook Pro) do have the playhead operating as I expected with "in" and "out" - hence I can edit them as I originally expected.

     

    Unfortunately most of my files are mpg's so I will need to work out how to use MPEG Streamclip for my editing - I have it already and have taken a quick look but there doesn't appear to be an editing facility in it? (although I can see soemthing called "trimming" in the bottom right of the screen).  Any tips on how to use MPEG Streamclip for editing?

  • Gary Scotland Level 6 Level 6 (10,180 points)

    MPEG Streamclip is very easy to use and the editing function is exactly like QT pro

    Thanks Gary, I'll take a look.

  • Jerry Dammers Level 1 Level 1 (0 points)

    My other video files are .mov files (and some even older files are .mpg). 

     

    I am using the "Export to QuickTime" option within "File" - is that right?

     

    I then see a set of "compression" settings. What should I select to get .mov files - is it "Apple Intermediate Codec"?

     

    Thanks.

    You are exporting  MPEG files from  MPEG Streamclip, to then edit in QT Pro?

     

    I would use QT DV,  as your originals are from VHS and Beta, exporting to a higher bit rate codec wont gain any advantage in quality or efficiency.

  • Jerry Dammers Level 1 Level 1 (0 points)

    Sorry, I wasn't clear enough.

     

    I am now trying to convert DVDs into files that I can edit in QTP or MPEG Streamclip.

     

    My other video files are .mov (VHS to Mac) and some older .mpg (Betamax to Windows to Mac).

     

    Once I have all the video files electronically, including the DVDs, I will then edit them in QTP or MPEG Streamclip.

     

    I was presuming I'd convert the DVDs into .mov files via MOEG Streamclip, but that option doesn't seem to be present.

     

    Would you still suggest QT DV for the DVDs?

     

    Many thanks.

  • Gary Scotland Level 6 Level 6 (10,180 points)

    QT DV is still a reasonable CODEC to use.

    Any DVD converted files I get are edited with QT DV and they are indistinguishable from the originals.

     

    The tutorial I posted earlier will guide you through converting DVD video to QT files.

    Streamclip will only convert non commercial non copyright protected discs.

  • Jerry Dammers Level 1 Level 1 (0 points)

    Thanks - what is the "apple intermediate codec" option? I vaguely recall selecting this previously when I used MPEG Streamclip, but can't recall why.
