still frames degrade in quality over time

Jul 24, 2012 8:44 PM

I have a lot of footage that was recorded from my screen and saved as uncompressed avi. During the video, this footage is played, and then paused so that the viewer can look at a specific thing. To pause the footage, I have been cutting the footage and extending a single frame for the duration of the time needed. After rendering the video (.mp4), the paused footage changes in quality for no apparent reason. Sometimes it is clear, sometimes it is degraded so that text is not readable.

 

Any suggestions for what I can do to keep the footage quality more consistent?

    Are you saving the footage as progressive? Or interlaced? What are your sequence settings and resolution etc?

    is there any way to change the sequence settings  or place all of the edited footage in new, matching sequences without essentially re-editing the whole film?

    Yes. Drag one of your source clips over the 'new item' icon to create a new sequence to match it... or create a new HDV (or whatever format you want) sequence using the presets and modifying its settings as needed.

     

    Then copy and paste fromt the old sequence to the new one. It should remeber most, if not all, of all the edits you made in the first sequence. If you have a lot of nested sequences and such, it could get tricky...

    It shouldn't be a long process. Just create your new sequence then select everything and copy and paste it all at once... It will remember your trims, effects, etc...

    OH, yeah, the nested sequences may be a problem.  I abuse PrPro regularly by using it as a compositng tool and have copied and pasted that stuff successfully, but not so much with a nested sequnce scenario. I just stack images in tracks and use the ECP to animate them, and then group things as needed. But I'm not suggesting that workflow, because it's sub-optimal, as you've discovered...

     

    You have my empathy. Let me know how it goes.
