![]() I was referring to a Preference > Video System in Color Finesse. “…Video Level Coding to 0 – 255 instead of 16 – 235….” I am hoping someone can verify the pattern or perhaps has dealt with this issue before in After Effects. And as I said, I believe mine is correct. I trust my SMPTE calibration pattern more than what I could find. So, my point was, I didn’t trust anything on the internet. Something so simple has become quite frustrating. I attached my preferences I set in Color Finesse to help show that. I then spent hours re-starting my machine, trying different settings, and verifying everything I could. I put the same into After Effects, and was shocked by how I couldn’t get it to show correctly on the scopes. Scopes show everything as I would expect. Works great for calibration in that environment. It’s possible you don’t know where it’s been!” It’s been generated by Vegas Pro where I’ve used a lot there. You said, “I’d be skeptical about the accuracy of that color bar image. You said, “Video Level Coding to 0 – 255 instead of 16 – 235.” Where is this set in After Effects? I’ll try to look for it. So I figured there are others who could confirm.Īgain, I think the one I attached is CORRECT. □ Calibration is a pretty basic thing to do. I was hoping someone could throw it up on maybe something they had briefly and verify I’m not going crazy. However, now that I am doing more advanced stuff, I’m verifying things in After Effects and was surprised when my scopes weren’t what I expected. I generated it using Vegas Pro and have used it heavily there for other work. The one I’ve attached are 75% SMPTE NTSC color bars. So, it’s not really that ‘hard’ to reproduce if you know what the colors are to be. What makes the SMPTE bars unique is the layout. However, there are only a few specific colors. One can forget this since it’s such a helpful pattern and so useful for calibration. To answer you question: I’m not absolutely sure, but you may want to try setting Video Level Coding to 0 – 255 instead of 16 – 235. Many camera manufacturers also create their own version of color bars that are very similar to SMPTE bars, but they are not called “SMPTE Color Bars” and might not exactly match the standard. FYI – Premiere Pro does generate bars that look pretty accurate on my hardware scopes. ![]() So, if you are using a still image to create bars, then you might find that the original is not exact, or that whatever compression scheme used caused some variation from the standard. You do get bars overlaid with the name of any missing footage, but I’ve never been sure how ‘correct’ they are. AFAIK, neither After Effects nor Finesse has any provision to purposely generate color bars. You didn’t say where your color bars originate. My guess is that it can be implemented in a small chip these days. (Although I did find numerous references in google just now.) Devices to generate precise color bars used to be expensive rack-mounted hardware involving temperature-controlled ovens for the internal reference clock. It is a very-precisely defined standard “owned” by the SMPTE, which is one reason it may be difficult to find. IIRC, the Society of Motion Picture and Television Engineers (SMPTE) refers to this test pattern as Engineering Guideline EG1-1990. SMPTE color bars is a television test pattern used where the NTSC video standard is common. Does anyone have a direct link to an offical SMPTE color bar that I can download? I kept thinking there was something wrong with my color bars, but I’ve compared it to other ones I have and it seems correct. Last, I was shocked to see how difficult it is to find an OFFICAL SMPTE color bar on the internet. ![]() I have no idea why I am seeing this on my scopes in After Effects! Has anyone else come across this? ![]() Here is the exact SMPTE Color bar I am using as my official reference in After Effects: This is where it’s wrong on the scope in Color Finesse 3: The settings I have for the Color Finesse 3 in the preferences is: Here is the output of the Color Finesse 3 Luma scope for the levels:Ĭolor Finesse 3 SMPTE Color Bars Luma Scope Out of After Effects, I have run the SMPTE Color Bars through other scopes and they appear correct.Īnd, I seriously have spent a few hours fiddiling with After Effects to figure out why the scope levels are so very off? I have no idea! I’ve given up. I am getting wrong SMPTE Color Bars in the scopes for the After Effect’s Color Finesse 3 Plugin. ![]()
