Fixing dropped frames in action cam footage? (for stereoscopic 3D) (Page 7 of 8)

Here is my tiny zip file of the several zipfiles.  I realize you don't need Interframe, but as my script uses it, I include it.  For our tests though, I envision us chopping off all of the script after GameDropFix4.

I should have suspected there'd be a problem if I allowed an apostrophe to be in the file name.  When I tested the link, I didn't go as far as saving it, but believed if I got a save dialog, it would work.  No, it gave me a 404, too.  Had to rename it on the server to not have apostrophe, and respell the link.  It now woriks.  (Maybe bbcode has a way to allow, but didn't want to research it.)  Link now works.

In your script I did 6 modifications:
mod1. added distributor() to the end of script. It lets script to use multi-thread processing. Significant speedup in AvsPmod and player. For x264 and AVSMeter it is not necessary
mod2. added SetMTMode(1) just after AudioDub(video,audio) to to less memory use
mod3. moved AddBorders(0,0,0,8) just after GameDropFix line. It gives more quality to interpolated frames
mod4. change global threads=4 to global threads=7 to use more CPU to get more speed
mod5. use GameDropFixV5 instead of GameDropFix4
mod6. change Interframe call to DblFPS=true parameter inside GameDropFixV5

Script before changes: GDFv4_speed.png - 59 fps
Script after changes: GDFv5_speed.png - 84 fps

Your sample is just telecined. 24-in-the-30 fps. You need to make decimation. IVTC.
You can use TIVTC plugin and simple script to restore 24 fps from 30 fps:

TDecimate(cycle=5)

How many 24 fps cartoon scenes in that "hybrid" 30 fps video?

Couldn't you cheat and just make a variable framerate video with both 24fps and 30fps without telecine?

Of course, I have absolutely no idea on how to achieve such a thing...

Hi! I tried to read this thread, and if I understood correctly it detects dropped frames and replaces them with interpolated ones.

Would there be a way to tweak also frames that are not dropped? I'm getting incredibly smooth results, but then there are also "lagged" frames (captured with Open Broadcaster Software) that are just before or after the position where they actually should have been.
E.g. frame 28 should in fact have been frame 27 or the other way around. I suppose the way to do it would be to analyze the optical flow and detect sudden (unwanted) changes in the speed to find these bad frames.

Secondly, some feedback: My graphics driver is old so I had to disable GPU to prevent crash. I was also forced to set thread count to 1, otherwise I could see glitches in the output, the frames would be mixed up a bit about once every second.
It also appears to have some problems at the start of the video, lots of glitches there.

Thanks SO much for all this work, Mag!  I've just now been able to start to tackle usage.  I didn't even download more than the avsi (and change v4 to v5), and my script works!  (The script opens in Vdub and I can scrub forward a bit.)

The one item I am worried about is that when I first started using InterFrame, I was only able to get it to work with any degree of meaningfulness by using the Tuning="Film" setting.  I don't see how you are setting that in the case of DblFPS=true.  Could you please confirm that if I set DblFPS to true, that it will invoke the InterFrame logic with Tuning equal to "Film"?   (I will be very happy to now be able to leave out the InterFrame call in all cases where doubling the frame rate is exactly what I need.)

Can't download file TCMullet's-GDF-test-scripts2.zip.

Thanks. It works. I got all your files. I will look them.
What Preset you using in InterFrame with "Film" tuning?

I repeat, your question doesn't make sense to me.  The line to call Interframe is:

Interframe(Cores=4, Tuning="Film", GPU=true)

So "Film" is the value I set for "Tuning".  The parameters to Interframe are the only way (to my knowledge) to send info *into* Interframe.  Those parameters (3 in this case) are what I "preset" Interframe to.

As to the absence of further action by either of us these several months, (1) I don't know why you've not responded.  And (2), my video circumstances have changed to where most of the files I deal with do NOT need the SR() tool to smart-resize to a larger size.  But I still do have many files where I must use both GDF and SR(), and GDFv5 is still crashing or hanging the system ONLY when SR() is included.  You can use SR() for free, as the artifacts shouldn't affect this test for crashing.

To get around this problem I have to do something very aggravating.  I have to revert to GDFv4.  But when I do that, I cannot run my whole video (1.5 to 2.5 hours long) through Avisynth/Vdub processing in one piece or it will crash due to the memory leak problem of GDFv4.  But it is very tedious to have to break up my video into 20 min. pieces, then after creating the several AVIs, concatenate them back together.  It would be so nice if we could find out why GDFv5 is crashing whenever SR() is present.

GameDropFix, version 5.01

New in this version 5.01:
- updated to last versions of plugins: MVTools 2.5.11.22, SVPFlow1.dll 4.0.0.132, SVPFlow2 4.0.0.136;
- no script code changes.

Usage:
- to fix dropped frames with GPU:

GameDropFixV5()

- to fix dropped frames with GPU and double framerate by insert interpolated frames:

GameDropFixV5(DblFPS=true)

- to fix dropped frames with debug info:

GameDropFixV5(myDebug=true)

Sample script:

SetMTMode(3,4)
DirectShowSource("video.mp4")
SetMTMode(2)
GameDropFixV5()
Distributor()
