built in estimator and 120fps support?

[garyfitzg]

Reclock's built in estimator has no problem identifying 24fps and 48fps H264 streams as CINEMA and CINEMA(2x), but the built in estimator wont ever "find" 120fps H264 video streams and consequently doesnt adjust the playback speed to sync to refresh rate (120Hz). Neither is it possible to manually set 119/120fps in Reclock nor the Reclock Config :bang:

The thing that baffles me most, is that Reclock absolutely sees the 120fps frame rate correctly and even shows it in the media adaptation area (~119.9fps), and the changelog says the built in estimator supports detection of 120fps, and from everything I've read, this _should_ work... but it just doesn't?

If anyone can provide some assistance to get this working or even an explanation of why it's not I would be most grateful!

After some more fooling around, it appears MPEG2 streams do get detected correctly as CUSTOM and properly adjusted to 120.000 fps as expected, but with H264 streams Reclock's built-in estimator behaves as described in the original post (24=CINEMA, 48=CINEMA(2x), 120=unknown)...

more testing with the built in estimator:

23.976 H264 or MPEG2 = video stream picked up as CINEMA and adjusted to 24fps for 120Hz playback
47.952 H264 or MPEG2 = video stream picked up as CINEMA(2x) and adjusted to 48fps for 96Hz playback
119.88 H264 = no video stream found, media played at original speed (estimator knows the frame rate but reclock wont kick in)
119.88 MPEG2 = video stream picked up as CUSTOM, and adjusted to 120fps for 120Hz playback
125.00 H264 or MPEG2 = video stream picked up as CUSTOM, and slowed down to 120fps for 120Hz playback

So there is something fishy going on here... clearly the framerate estimator is working as intended, and Reclock behaves exactly as expected and adjusts for synched playback in each case, but not when the estimator detects a 119.88 fps H264 video stream :doh:

Svp

I have the same problem with SVP (SmoothVideo Project). When “Target frame rate = source multiplied by 2 (x2)” in SVP all is OK, Reclock shows video stream 47.952/48.000 or 50.000 fps in Automatic (depending of the video original framrate : 23.976/24/25 fps).
But if “Target frame rate = source multiplied by 4 (x4)” in SVP, only videos with original framrate of 25 fps is OK, Reclock shows video stream 100.000 fps in Automatic.
But for video with original framrate of 23.976 or 24 fps it’s KO !, Reclock shows video stream No video stream found / Unknow …

Example with 23.976 fps original framerate :

Which is weird : estimated framrate is ok (95.905 fps) !!!

The problem is reclock because any H264 file with frame rate of 95.904 or 96 fps : I have the same problem ...

You can test with this file (95.904 fps).

I have tested 1.8.8.3 ... but still the same problem

What is strange is that for 96000/1001fps video if I select manually in reclocks 23.976 (it's say "CINEMA adaptation: media speed changed to 24.000 fps"). but in MPC HC i have correct 96.000 fps and sync is perfect ?!
