PD14 degrades footage once dragged to project timeline, but not when still in media lib

I have a distinct problem that's going to make me toss any PD at all from this point on. PD14 when importing video to timeline looks nice and crisp. I'm taking screen capture on a desktop from a program I'm making videos about (actually it's a tablet, but still works)

I use OBS to capture into MP4 files, with multiple audio tracks.

When I import that footage, I get crisp clean footage, but when I start to edit down the line it becomes degraded. In this case it wasn't apparent until I opened the preview window to full screen, and needless to say if this is permanent, PD made me lose hours of editing unless I upload this to Youtube as is.

But turns out it's fine if I restart and reload the file. For some reason the degradation is gone. At least THAT is a solution (as I was really pissed writing this and decided to restart the program)

But how do I avoid this? The editing changes I make is also sluggish. It's as if there is a memory leak in the program.

Hi nathanpinard,

1. Preview player resolution settings, check to see what it is set to, see the icon under the player.
2. Are you generating Shadow Files? These are low resolution mpeg2 replacement video to make editing easier for those with low powered computers (or necessary for 4K editing)
3. Is your computer spec and importantly your graphics card, up to sufficient spec to be able to display the software and the video from the tracks. Provide your diagnostic data, see Part B in the guide.

Appears to me this isn't an actual program issue in as much as there are options to make changes in the program, to alter the visual display or where the cause is one where dumbing down the resolution is to assist your computer. The diagnostic will show us more and let members guide you to a "better" solution.

I hadn't updated my nVidia drivers yet (I have a Titan) so I just did that. I'll try again and see if it fixed the issue.

Please understand the degradation occurs on producing a film also, not just in the preview. I understand how the preview works. Not having proper resolution in preview doesn't bother me, I had expected the file generated to not have that preview look though. (The original footage is high res, but not 4k)

Degradation in Production = got to have more info please.
1. Screenshot of the project insitu.
2. MediaInfo on the original footage.
3. Selection in Produce, what are you selecting as the output?
Still need the diagnostic data.
See Part A, B, E,F and J in the guide.
My guess is in what you're original video is and in what you're selecting as the output. Degradation can occur when one compressed format is then re-compressed into a different format/codec. For example mp4 to mp4 with the same compatible profile (even using SVRT) is likely to be ok. if you try to compress from wmv with a low bitrate to an mts you might see issue (just given as a difference and not as an actual issue problem).

Info is the key to you getting help here.
