Drastic quality loss high-fps uncompressed .avis
Here are two screenshots from uncompressed .avis at the same resolution, the first from the raw file and the second an export from after effects. Over the past few days I’ve been completely bemused as to what’s going on with my quality issues, with the odd shot im working on within my gaming montage being affected by this bug. Does anyone at all have a clue as to what could be causing this?
This quality loss is apparent at full quality in the preview window as well so it wouldn’t be anything to do with render settings even if they were (they’re not) causing it. This points to the issue being with AE struggling(?) with it.
The footage is fine in a program such as Sony Vegas, and exports without quality loss, but After effects it is not.
If I render the .avi from Sony Vegas and THEN put it into AE rather than a direct import, the image quality will not distort. Could After Effects be struggling to interprate/work with uncompressed .avis ranging from 500fps-2500fps? The footage is being interpreted at its original FPS and the project is 32 bit / 60fps @ 1920 x 1080p.My question to you is what can I do about this? Is there a setting that I have somehow messed up that’s causing the image quality to mess up. I’m completely lost. Any help would be truly appreciated.
Thanks for your time

What exactly are you exporting from After Effects?

Looks like you’re losing half the resolution. Maybe you’re interpreting the footage as interlaced? (Check your interpret footage settings.)

Thanks for the response. The particular game in mind called Counter-Strike has an in-built recorder that allows one to export .tga’s files at any set frame rate, limitless. These tgas are compiled by ‘VirtualDub’ at the set rate allowing for files that are indeed true to the set frame rate (i.e i can record at 10k fps and use 1% speed and maintain complete smoothness). The high frame rate as you would imagine is for slow-mo use like you say, the final export is 60fps.
I haven’t yet come to any conclusion to the issue, but it hasn’t lost me a ridiculous amount of time so I’ve just used a work around to address the problem shots.
Thanks for the responses guys 🙂

Is there a reason why you aren’t using these TARGA sequences in AE?
