    MC Newbie Questions

    While i have some decent prior experience with basic video editing, I was able to quickly learn enough about MC to actually receive a small but regular job offer.  But in the learning process, i made a pretty substantial mistake that nearly cost me the opportunity.

    I was provided with an original MP4 that was to be edited.  Just a single file is all this project required.

    I imported it into MC, made the edits and changes up to a certain point, then submitted what i had.

    In the course of editing, I realized that the video as i was working on it in MC did not have the same high quality as the original source material.  Blurrier, and possibly even the wrong aspect ratio.

    I obviously made a mistake during import, probably having set up the project wrong.

    My two questions are:

    1.  I definitely want to keep the edit work i have done so far, as the client wishes for me to continue.  However, I obviously have to fix the quality/ratio issue.  Is there a way for me to create a new project and properly import the media, then import my edits to date and have them still be correct in the new project?

    2.  Before I even try to fix it, how can i get ALL the details I need about the source material, such that importing it into MC doesn't change it in any way?  How do the attributes I might see about the video (in whatever app/widget whatever you recommend) transate to project settings?

    Thanks for any help you can offer!

    Hi funaroma,

     While you are waiting for the experts to step in,   right click from the "Format" button to open up the help menu, type in "Change project format" and "Changing the Sequence Format". The information might help.

    Re: MC Newbie Questions

    Thanks.  Here is the original file details as displayed in MPEG Streamclip:

    Duration: 0:55:12
    Data Size: 576.12 MB
    Bit Rate: 1.46 Mbps

    Video Tracks:
    JVT/AVC Coding, 2560 × 1600, 30 fps, 1.22 Mbps

    Audio Tracks:
    MPEG-4 Audio stereo, 44.1 kHz, 243 kbps

     

    if this is the only file used, and i want my export from MC to match this, what project settings SHOULD I use?  And doesn't the fact that I imported this file with the wrong project settings mean that the imported video and audio have taken on those project specs, and therefore I would need to re-import the original after finding the correct project settings?

    Re: MC Newbie Questions

    Also, from further research, that resolution seems to imply this Aspect Ratio (name) so i guess i need to figure out how to set up media composer for that.

    WQXGA = 16:10 =
    2560 x 1600

    Re: MC Newbie Questions

    Odd resolutions can end up really dicey. Most recommended workflow is to import to DNx and edit in that format, then determining what the customer is going to do with the finished product, 16x10 is not as common as 16x9 and may cause some loss of quality.

    That bit rate is really low for the resolution. Is this a game capture?

    Re: MC Newbie Questions

    I will attempt re-import, to DNx.  I have no idea though how to get the sequence to use the newly imported version of the raw footage, and get rid of the old raw footage and all associated files.

    Something else I read, i think, is that I could remove the current source video, relink somehow to the raw footage using AMA Link (?), and somehow get the sequence to use that instead... and then export just what the sequence has used when the project is done, and in the resolution/aspect ratio needed.  Then there's no importing at all, so no change to resolution or aspect, and then just configure the export properly to avoid degrading the quality and skewing the aspect.

    Ultimately I think the client wants their edited projects returned to them as MP4s with the same resolution and aspect as the raw footage, so i really need to know how to do that.  I don't see a 16:10 setting in MC, and i'm just really confused.  =(

    Re: MC Newbie Questions

    sorry, i didn't answer your other question...

    I'm not sure what the client is using, but the video is a screencap from a Retina. The video itself is a combination of webcam/video in lower right of a presenter, and screencap of their browser as they view/visit web pages.

    Re: MC Newbie Questions

    Is there someplace else I can post, where i can get information and assistance faster?  I'm in a bit of a bind at this point, and very confused.  Need someone to hand-hold a newb for this specific project.  It's all a bunch of edits to a SINGLE source file.  I can even go without the titling work i did, as there was only three.  But I really don't want to start over if I don't have to, if I can simply change the source video for a sequence so it's using the HD version of the raw file directly, or via import that preserves the attributes of the raw file (16:10).

     

    Help!

    What version of Media Composer are you using?  I ask because newer versions have capabilities that can help, but it's pointless to suggest them if you're on an older version.

    i did an IMPORT (not an AMA link) and I think the project format at the time was DV 25 411 (based on what I see in the sequence / clip resolutions text).  I literally didn't know what i was doing, of course.

     

    I did some substantial editing using that imported file, but of course I am now unable to export at the original ratio, and apparently the original quality or better.

    I have discussed with the client the idea of allowing me to use MPEG Streamclip to convert the video down to 16:9 somehow (a standard ratio, using a program that was suggested to be used BEFORE importing into media composer), but would much rather just hand clients back their exact video attributes when the edits are done, in this case 16:10, 2560x1600, perhaps with better bit rate.

    So I need to get the current sequence to use some form of the raw video file somehow, so i don't have to do all the edits over, and in the correct project format.


    And I also need a really stiff drink right now.  =D

    Re: MC Newbie Questions

    You should consider upgrading to version 8.4, which introduced custom resolutions.  You could create a 2560x1600 project at 30fps, 709 color, and that should match your mp4 file.  Import or AMA/transcode the file using whatever video resolution your system can handle and doesn't use up all your hard drive space.

    Re: MC Newbie Questions

    i can do that i think, but I'd still need to figure out how to use my existing edits with the imported video.  And in the interests of not making even more dramatic changes to this system in the middle of a project, I'm not sure i want to pursue even a minor point release update just yet.

    So if I were to NOT upgrade, but just start a new project, how would i get the raw video into the project, and then get my existing edit sequence transferred in so that i can keep working and finish up this current project?  I really don't want to start over.

    Hi funaroma,

       Take a look at this thread, this explains how to transfer sequence from one project to another. It mgiht help.
