MKV H.264 Motion Test patterns (23.976, 24, 25, 29.97, 30, 50 , 59.94, & 60Hz)

-= 9/19 Update: See post 17 for the Rev. 3 (newest) clips. =-


-= 7/29 Update: Clips have been replaced with new rev 2 files =-


I made a variety of test clips for testing your playback chain's motion handling of different frame rate files. The test is rather simple. Play back the clip and watch it to see if the bars move smoothly. You can also use these clips to test the frame interpolation features of your display.

They are all in a mkv container with a 1 second silent MP3 "dummy" audio track. The video is H.264 encoded. There are 1080p clips for each of the frame rates. For the three 1080p Level 4.2 clips where the frame rates (50, 59.94, & 60) exceed the H.264 Level 4.1 specs I also made Level 4.1 compliant 720p clips. All of the clips start with a ~5 second pre-roll and then 10 minutes of consistent motion fluid. Each frame of the motion test is numbered and timestamped.

Example Screenshots:





The clips are in zip files.


Level 4.1 files:

1080p24/1.001 [23.976] (13.7MB)

1080p24 (14.7MB)

1080p25 (13.3MB)

1080p30/1.001 [29.97] (15.8MB)

1080p30 (15.9MB)

720p50 (13.1MB)

720p60/1.001 [59.94] (20.7MB)

720p60 (21.6MB)


Level 4.2 files:

1080p50 (17.0MB)

1080p60/1.001 [59.94] (21.1MB)

1080p60 (21.1MB)


Combined download:

7-zip file of all the above clips (157MB)

-= 7/29 Update: Clips have been replaced with new rev 2 files =-


-= 9/19 Update: See post 17 for the Rev. 3 (newest) clips. =-

Nice motion patterns. I've been using these similar ones for a couple years now:

These make it painfully obvious when your playback device (such as a HTPC) can't properly display the /1.001 frame rates without drops or repeats.

I hadn't seen those before. They don't seem perhaps as plasma or OLED friendly as they could be with those static horizontal bars. I originally had a F: and T: in front of the frame and time, but ended up removing them to prevent a static image. I also didn't make the counters pure white.

My problem isn't the HTPC, but my TV. The HTPC outputs the frame rates very accurately, but the TV seems to have random glitches in 24/1.001Hz content. I'm still not sure if it's tuned for 24Hz or 24/1.001. Neither works perfectly.

Have you verified it's not the HTPC by playing the patterns from a consumer BD player? Many of the Android and other cheap streamers also have problems with consistent frame rates.

I've attempted to confirm it's not the HTPC by relying on the frame drop / repeat counters in madVR. They do not increase while the glitches on the F8500 happen. I still need to test with another PC and see if it is any different. FWIW, I don't have a consumer BD player to test with. I'm going to see about borrowing one from a friend.

I've updated the first post. All the files have been replaced because I redid the clips to have 3 different motion speeds similar to the clips Wizziwig linked to in post #2 .

they all work 100 % perfect on my display.
for some reason the judder in your files is lower at 23p compared to the version posted from wizziwig.
most likely an speed/size issue.

What display and playback chain do you have?

I'm not aware of any CE display that can play back all of these files without any frame rate differential induced cadence judder (assuming you have a playback chain that can present them all to the display in the native frame rate of the clips).

i use a cheap old pf4604

it can do 23, 24, 25, 29, 30, 50, 59, 60 hz with full range RGB.
my clocks arn't perfect but that's not a problem of the display. without CRU i get a repeated frame every 20 ~min
i use madVR -> unlimited RGB -> HDMI.
i'm going to get a display for ~2k "soon" and this is not a normal feature?

Some newer displays accept lots of input frame rate possibilities, but unless the display uses a refresh rate that's an even multiple of the input frame rate, IMHO you're better off using smooth motion in madVR to eliminate uneven cadence judder.

Stereodude, have you tried playing these patterns through the TV's built-in media player directly from USB? If you still see issues, then you're probably right and it's the TV's processing. Do the 59.94 patterns also not work perfectly? That's the most common broadcast format here in USA so it would seem bizarre if they could not play that correctly.

59.94 patterns seem to work perfectly on the TV over HDMI from the HTPC. I borrowed an old standalone Blu-ray player from a friend and tried it with a burned AVC-HD disc, but I'm pretty sure it outputs 24Hz, not 23.976. There seems to be a glitch in playback every 40 something seconds, but I'm not entirely sure. The HTPC seems to do better than that. I also tried my laptop and it seemed okay, though I didn't watch it for too long.

Futher, I think I need to modify test patterns again. It seems the bouncing effect of the bars creates some sort of optical illusion as my brain is tracking the various bars. When the fastest top bars change direction (bounce) the motion of the other bars seems to slightly hesitate or pause. I perceive the same effect in pretty much all the clips, even on other displays. I know what I'm perceiving isn't in the clips but that makes it harder to identify glitches/hiccups in the motion.

Plasmas need a constant framerate matching the output rate, this is why madvr smooth motion works so well. I'm not sure what is happening with your screen but if it is glitching out at 60hz that doesn't leave you with many options, there is a way to check for dropped frames at the testufo site (you may need close down some applications and update your browser to get some of the test running smoothly).

If it is confirmed you are dropping frames maybe an EDID override could be the solution to your problem.

I generated some new test patterns, but haven't tested with them yet. So far 60/1.001 seems okay. I haven't noticed any hiccups/glitches during real 60/1.001 content. On the other hand I have with 24/1.001 content.

Your link goes to a website with a lot of convoluted, bait and switch crapware, and generally suspicious behavior. But, I did manage to dl your videos which are nice and appreciated. It took forever for a small file, maybe to get you to install their downloader?

I'm not really sure what you're talking about... I'll admit it's not the perfect or ideal host, but it's free and will host these kinds of files. It serves the exact zip file I uploaded. They didn't add anything to the zip file. You don't have to download some utility to get them. I even tried a link in IE to see if there was some malicious stuff going on that my FireFox add-ons were blocking/preventing, but didn't see a problem.



It's not obvious that you need to click on the link in the blue box that I have highlighted in red?

If you know of a better free host I'm all ears, but AFAIK, this is one of the better ones. Ultimately, if you don't like the host, don't download the files.

So I finally got around to completing my 3rd revision of the test patterns. I have eliminated the "bouncing" since I think it made it hard to perceive playback glitches when the bars bounced. Instead I made the motion consistent left to right.



Here's a link to a 7-zip archive of all 11 .mkv files.
