[Invalid] [SVN 2263] Incorrect Framerate

Post by downinitjr »

Have noticed this with several files now. MediaInfo for mac reports source file as 23.976 fps. TV preset is being used with the exception of changing RF: value to 22, picture size to 1280 x * and turning off create chapter markers. The resulting .m4v file comes out as 40.961 fps? Anyone else seeing this, or knows whats happening here?

....if you want a constant FPS, then select a constant FPS.

This is not a bug. Your source file must be VFR.

I've experienced similar results with Same as source frame rate.

I ran a test on a very short clip, from what was supposed to be a 23.976 fps source, and the resulting file is reported as 35.82 fps by QuickTime.

So my source is VFR, OK.

But then, I ran a deinterlace with JES Deinterlacer (because it reports what appears to be the total number of frames while deinterlacing), on the source Test.mpeg file and on the Test.mp4 produced by HandBrake. It seems that they could have a different number of frames: 163 frames are reported for the original, and 248 for the file produced by HandBrake. The HandBrake encode log, however, seems to report 163 frames like the source.

But then why is JES Deinterlacer trying to deinterlace 248 frames? What other utility can I use to check the total number of frames for the source and destination files (I used JES Deinterlacer because I don't know anything else, but it's not designed for that purpose)?

Also, I've noticed that Test.mp4 gives a "No valid title found" error when you try to select it as a source in HandBrake.

I just did an encode of Test.mpeg with FFmpeg instead of x264 and QuickTime reports the file as being 23.54 fps?

I noticed that (around 59.940 fps), but couldn't it be that this is incorrect? The data rate clearly isn't 9.8 Mbps either.

What does this line mean, for example?

Code: Select all

[20:41:41] sync: got 164 frames, 478 expected
Also, why do I get a different framerate for the destination file when I encode using ffmpeg (23.54 fps) vs. x264 (35.82 fps, or 23.54*248/163)?

The data rate field is inaccurate (I just haven't gotten rid of removing it yet) but that has nothing to do with the FPS. My question is, why are you saying the source is "supposed" to be 23.976 when there's nothing to indicate that?

It means that based on the stated framerate and duration of the file, 478 frames were expected, and it didn't get anywhere near that many, since your source doesn't follow the stated framerate, because it's VFR.
Also, why do I get a different framerate for the destination file when I encode using ffmpeg (23.54 fps) vs. x264 (35.82 fps, or 23.54*248/163)?
I would assume something to do with the init_delay and track edit used to maintain AV sync when using B-frames having a large influence on the calculated FPS in QuickTime, averaging over such a small total number of frames.

It's the Stargate SG-1 pilot episode (again), which I ripped from an NTSC DVD. First, I opened it in Streamclip and extracted a very short clip which I saved using "Convert to MPEG". That MPEG file is reported as 23.976 fps in QuickTime.

Then I must presume your issue is with your choice of extraction tools.

So you're saying my file is not even around 23.976 fps?

I'm saying that, apparently, Streamclip is signaling an incorrect FPS for its output, leading sync to expect a wildly increased number of frames.

As I already told you, QuickTime does not work off the signaled FPS, but rather displays an accurate calculation of the average fps based on individual frame durations and total frame count.

Interestingly, I hadn't though of Streamclip as the source of the issue. I've only used it to get a very short sample of the episode out of the VIDEO_TS folder. I guess it could be the reason my video is reported as 59.94 fps.

However, I don't think that's causing the issue. I've done 4 more encodes:

First, using x264 defaults

QuickTime (with Perian) reports 24 fps for this source, and apparently so does HandBrake:

Code: Select all

[23:27:54]    + frame rate: same as source (around 24.000 fps)
Yet, QuickTime reports 40.01 fps for the encoded .mp4 file! I wonder whether this is a QuickTime issue?

...really don't know what you're trying to show with all those logs.
I guess it could be the reason my video is reported as 59.94 fps.

However, I don't think that's causing the issue.
You're ignoring the other half of my explanation:
I would assume something to do with the init_delay and track edit used to maintain AV sync when using B-frames having a large influence on the calculated FPS in QuickTime, averaging over such a small total number of frames.

The last log corresponds to a 10-minute source, not 6 seconds like my other test clip.

...and are you going to test it without b-frames? That's what I was implying you should do by reminding you that using b-frames can confuse the FPS calculation in QT....

Overall, you seem to be really focused on the difference between the FPS scan reports and the FPS QT reports, and I'm trying to remind you that they are different things calculated totally different ways. That a stream signals that it's 24.00 means absolutely nothing. It's just metadata used to estimate the expected number of frames. What's important are the actual differences between each PTS in the file. The init_delay is not changing based on the signaled FPS, when you use Same as source.

I'm still not sure what this bug thread is a*bout*. What is the problem here? Is your output not playing correctly? If not, what are you concerned about?

I don't know about rodeo, but the reason I started this thread was because after using the tv preset on many different .mkv files, I have just recently started seeing the issue reported. Up until now all of the re-encodes I have done have worked fine on my tv without ever having to change <same as source> to a specified frame-rate. I was under the assumption that when mediaInfo was telling me it's 23.976 fps, that same as source would produce 23.976 fps as well. It has only been recently that I have been getting files on occasion that will not show up or sync to the tv, and after opening the files in quicktime find the reported framerate different than what I thought it would produce. I suppose it could have been just blind luck that I never experienced this up until now which is why I was checking here.

Without b-frames, QuickTime reports the file as 24.00 fps.

I posted in this thread because it seemed related to what I was experiencing (weird fps being reported). Also, after the "test" I did with JES Deinterlacer, I was worried that maybe HandBrake was actually adding frames to the files it created (although, being QuickTime-based, JES Deinterlacer was probably just confused like QuickTime appears to be).

I did notice, however, that encoding with same as source fps and b-frames may sometimes unnecessarily increase the bitrate.

I did two more encodes of Big Buck Bunny: one with b-frames and constant 24 fps, and one without b-frames with constant 24 fps. So now I have 4 encodes of Big Buck Bunny to compare:

1) Constant 24 fps & no b-frames

4) Same as source & 2 b-frames (log can be found in my previous post)

All other settings should be the same (60% quality, 128 Kbps AAC, ref=2:me=umh etc.).

File (1) gets reported by QuickTime as "24 fps".
From log:

Code: Select all

x264 [info]: PSNR Mean Y:47.745 U:52.709 V:53.406 Avg:48.778 Global:46.596 kb/s:5465.34
File (2) gets reported by QuickTime as "24.00 fps".
From log:

x264 [info]: PSNR Mean Y:47.745 U:52.709 V:53.406 Avg:48.778 Global:46.596 kb/s:5465.34
Here, the only apparent difference is that QuickTime reports 24.00 fps instead of 24 for the same as source encode. Other than that, choosing constant 24 fps instead of same as source doesn't appear to have any obvious effect.

File (3) gets reported by QuickTime as "24 fps".
From log:

Code: Select all

x264 [info]: PSNR Mean Y:47.423 U:52.651 V:53.374 Avg:48.498 Global:46.656 kb/s:4645.96
Here it appears that b-frames help reduce the bitrate (FWIW).

Finally, file (4) gets reported by QuickTime as "40.00 fps".
From log:

Code: Select all

x264 [info]: PSNR Mean Y:48.687 U:53.358 V:54.037 Avg:49.681 Global:47.781 kb/s:4204.25
Now here's the interesting part. While for files (1), (2) and (3), the bitrate found in the encode logs matches what's reported by QuickTime and MediaInfo, for file (4), this is not the case. I mean, the bitrate is nowhere near 4204.25 Kbps; in fact, it's 7007 Kbps (according to MediaInfo - QuickTime reports 7142 Kbps but that includes the audio). The size on disk corresponds to the MediaInfo- and QuickTime-reported bitrate.

At first I though I got my logs and encodes mixed up, but I double checked and triple checked, and the log (the one in my previous post of Sat Mar 28, 2009 12:40 am) corresponds to the file that's 7007 Kbps. I'll run another encode soon with the same settings, just to be sure…

Here's another log (sorry), which confirms the log vs. real bitrate discrepancy:

You're getting different numbers of frames processed by x264 than are rendered by libhb. Odd, to say the least. The vfr encode has waaaaaaay more P-frames that it should.

This looks resolved in 2288.

With svn2288, HandBrake now detects the framerate of my Test.mpeg clip properly ("around 23.976 fps" instead of "around 59.940 fps").

I still have the same issue with Big Buck Bunny though (bitrate discrepancy and 40.00fps when using same as source combined with bframes).

Re: [Invalid] [SVN 2263] Incorrect Framerate

Post by Deleted User 11865 »

OK. Here's what I've seen so far in my tests (using HandBrake 0.9.3):

1) When encoding using x264 and "Same as source" framerate, QuickTime reports a different framerate depending on whether
a) b-frames are disabled
b) b-frames are enabled, b-pyramid is disabled
c) b-frames and b-pyramid are enabled

2) This framerate difference (which is most obvious when using settings b) is not the only difference, as in some cases I've observed a mismatch between the encode log's reported bitrate and the actual bitrate of the file.

3) More recently, I used QuickTime to advance through the files frame by frame, comparing a "good" encode (settings a) to a "bad" one (settings b) in scenes which contain movement. In the "good" file, each frame change seemed to trigger a change in the picture (even minimal), whereas in the "bad" file, sometimes the frame would change yet look exactly identical to the previous frame.

I've compiled svn2289, but the issues when using both "Same as source" and b-frames remain.

Then I've looked at HandBrake's sources and found a reference to b-frames and b-pyramid in libhb/encx264.c. I commented out lines 160 to 182 and rebuilt (not really knowing what I was doing, though).

With this change, the issues I experienced went away (no framerate difference depending on settings, no log vs. real bitrate mismatch). Of course, that's obviously not a fix, as the resulting file doesn't playback smoothly (and if those lines of code weren't necessary, they wouldn't have been there in the first place).

However, it does seem to indicate that setting job->areBframes to true is triggering this framerate/bitrate issue.

FWIW, here are the logs for two encodes with and without my change:

Re: [Invalid] [SVN 2263] Incorrect Framerate

Post by Deleted User 11865 »

After briefly looking at this topic, I decided to try another experiment, and instead of commenting out lines 160 to 182 of encx264.c, to increase the number by which pv->init_delay is multiplied, setting job->areBframes to a higher value of 4 instead of 1 or 2 (lines 164, 175 and 180).

With this change, I now get the same framerate whether b-frames are enabled or not (and the bitrate matches).

Also, I noticed that encoding with jbrjake's suggested test settings (in the topic above) of bframes=16:b-pyramid:no-b-adapt seems to "hide" the problem, i.e. I get the same framerate as with bframes disabled (and bitrate match) in either 0.9.3 or svn2289 (unlike when using only bframes=2).

Up until now all of the re-encodes I have done have worked fine on my tv without ever having to change <same as source> to a specified frame-rate. I was under the assumption that when mediaInfo was telling me it's 23.976 fps, that same as source would produce 23.976 fps as well. It has only been recently that I have been getting files on occasion that will not show up or sync to the tv, and after opening the files in quicktime find the reported framerate different than what I thought it would produce. I suppose it could have been just blind luck that I never experienced this up until now which is why I was checking here.
I've noticed this problem with several of the recent SVN builds too. Reading jbrbrake's comments is like trying to read a linux book, all theory. Man, If we want good looking video that will sync with the AppleTV, then my question is (and I think the original idea here) what setting should be used to achieve optimal quality without sacrificing compatibility? Do we need to specify FPS from this point forward with all titles? If so, why the change? I just know that manually setting the FPS makes the files play oddly and a bit jittery @ 23.976FPS. In my case, Handbrake SVN builds (recent only) are identifying my titles as 24fps instead of 23.976fps and then outputting wildly high FPS when using same as source. Like this...

Whereas (and I can't remember the SVN build, but it is almost a month old) shows...

So, again, should I be choosing same as source, 24FPS, or 23.976FPS for titles like these? I think that's what we all want to know so we can sync these suckers up! :D
