    Idea [I] Saving parts of a Video without losing quality - Workflow by towbar

    towbar:

    This is how I mass produce small individual clips from a single video. This can be done all in one project, and works really well. I typically don’t use scene detection in my workflow, so my original video only shows up as one big timeline without any cuts. To follow my instructions properly, you will have to capture with scene detection turned off. Or you could add all of your scenes, select all, right click and combine all of them into one big timeline. There might be variations of this process, so adapt as you see fit.

     

    Start off by editing the video in the timeline, making all of the cuts to create the individual scenes you wish to have, and discard all of the unwanted parts. When finished editing the video, you will have a series of individual scenes on the timeline. Each scene will be its’ individual file, and each scene will be rendered one at a time. Just to make things clear, if you see 8 scenes on the timeline, you will render 8 separate files from this project. If there are two or more clips that need to be rendered as one file, it’s up to memory as to which go together. Regardless, they need to be side by side on the timeline. Always make sure to include enough leader before and after each clip to allow some extra time for transitions to work properly. Any extra or excess can be trimmed off when using these files at a later time. When each clip on the timeline plays as expected, proceed to the “Make Movie” section. The remainder of this process will be done there.

     

    Use the + or – keys, and resize the timeline to see all of the scenes in the window. This just makes the process visually understandable. Select the file type you wish to create. If the original video is .avi, then the best format to create the smaller files with is .avi. This just makes the process go really fast. Any other format can be selected, but the rendering may take a little longer.

     

    Select all but the first scene, and delete . All you have left on the timeline is the first scene. Proceed to make the file. When finished, hit the keys “Ctrl Z”, and all of the scenes will appear back on the timeline. Delete the first scene, because you’re finished with it. Select all but the first scene again, and delete . Now you have the “Second” clip on the timeline. Proceed to create the file again. Continue this process until finished with all of your clips.

     

    I’ve created hundreds of files this way, and it works really well.  The beauty of it all is that you never have to toggle back and forth between “edit” and “make”. Once you get the hang of it, the clips roll out real fast. If you are rendering to a format other than the original video, the process may be a little slower. But since I capture with .avi, I create my short clips with the same format for faster rendering.

     

    I posted this process many months ago, but somehow it got deleted. I’ve not included as many details this time, so let me know if something doesn’t work.

    Thanks for the process as described.  I am a new user with a family movie in an AVI file.

    My project is so large, I want to tackle it in chunks.  Working on a piece (chapter) and setting it aside once I have completed that part. Then I would start the final project, and just assemble the completed pieces to the the timeline and then output the final product.

    My question has to to with saving the intermediate chapters (files) to AVI file format.  Do I understand you correctly if you stay AVI all the way there is no loss in quality?  Do I need to make any settings - like uncompressed - before saving the intermediate pieces?

     TIA

    if you stay AVI all the way there is no loss in quality?

    Yup

    Do I need to make any settings - like uncompressed - before saving the intermediate pieces?

    Nope

    Colour answered correctly, but since he insisted that I jump in......

    Henry, it's wise to break the project into smaller chunks, and save the files (chapters) as you go. It seems to simplify things for me, eases the load on the computer by rendering as you go, and is a safety net in case of some sort of corruption of the Studio project. The described process works well for quickly breaking a video into smaller files. Any other variation of file creation will suffice as long as it works for you.

    The statement of lossless can lead to some disagreement if you are splitting hairs. But I haven't seen any loss of quality by rendering things to .avi again and again. I once rendered a file 10 times, and the last one was equal to the first one when viewed on a TV screen.

    I render my files to DV/AVI, which is the "Full Screen / DV" setting in Studio. I've never used any of the other settings with an .avi file.
