Video loosing black colours, .mp4 file with error

[Jon Doughtie]

I can only guess, based on the second shot, that the original material is h.264 MP4.

If that is the case, do you also see the artifacts in the original footage before rendering? If so, making an uncompressed version will not make them disappear.

You have custom AVI settings, but we cannot see them. We can see your output is 1920×1080, but that is about it.

System:
Dell Precision T7600 (x2)
Win 7 64-bit
32GB RAM
Adobe CC 2014 (as of 7/2015)
256GB SSD system drive
4 internal media drives RAID 5
Typically cutting short form from HD MP4 and P2 MXF.

You’re right. The source video is also h.264. There are also those black artifacts in the original video, bet they aren’t so slightly visible. I’ve made this project of various clips with different quality and those black artifacts after rendering are visible across all the video, now even in scenes where black color quality in source material was top-notch.
Usually I rendered in h.264 using these settings:

1920×1080
Frame rate: 23,976
Field order: Progressive
Aspect ratio: Square pixels(1.0)
NTSC
Main profile
Level 4.1
VB2, 2 Pass
Target bitrate: 6 Max bitrate: 8

Keeping everything as close to source material as possible. But now when I render in these settings, video seems to render as casual, but in the destination folder there’s just .mp4 file in size 24 bytes, consisting of error smt like this “Format file can’t be described”

So I decided to choose “Match Sequence Settings” and Premiere Pro renders it in .AVI format, but with those black artifacts. And, of course, massive in size.

.AVI settings:
IYUV codec
1920×1080
Frame rate: 23,976
Field order: Progressive
Aspect ratio: Square pixels(1.0)
Depth 24 bit

These are standard settings Premiere Pro gives me when I choose to have “Match Sequence Settings”

Most likely, I could resolve this problem if someone could answer, why Premiere Pro renders h.264 file in size 24 bytes with error? I’ve looked upon net, there are people complaining about this also, but no answer how to fix or why does it occurs.

I am using Adobe Premiere Pro CC.

Dont use Match Sequence settings it uses the preview codec which in you case is probably I frame only mpeg.
Pick a preset under H.264 to export.

My God, Thank You. Answer was so simple. I took 1080p 25fps template and it worked like a charm. Someone told me that it’s the best to match render settings to source settings, but now I know they can differ.

Still, I am again experiencing the same problem. If I change something in my project and play with clips, and then I want to render it again, I am using preset from H.264 and again I get 24 bytes video… First time it worked, second time it won’t.

Why does this keeps happening?
