Masking works fine when editing but the rendered video is messed up

[Leo Torres] “So maybe I clicked something that I shouldn’t have?”

To be honest, I haven’t a clue as to what your issues are. Leo, would you kindly describe what’s happening and what you’d expect to happen. Unfortunately from that YT I can’t discern what it is your asking. Sorry . . . ????

I’m sorry! It’s tough to explain exactly but I’ll try again. Ok so, I’m trying to mask the black area around the guy to have scenes behind him being played (like he’s in front of all the action). I masked the black areas around him frame by frame. At the beginning of the video you can see on the left side that was what I was masking, frame by frame. Then on the right side is the preview where the black areas are gone and the scene is being played behind him with no problems! Skip to about 19 seconds in and that video is the rendered project. I was playing it on VLC, Windows Media Player and even uploaded it to YouTube. Now, I play it frame by frame. Each time the character moves the masked area doesn’t until a frame later and it looks messed up. Like everything I masked is delayed a frame when it shouldn’t be.

Basically, my rendered video isn’t masked perfectly frame by frame but the preview in the program looks perfect frame by frame. I hope this was more clearer and thank you!

is the final render the same frame rate as the source files?

Most likely if you recorded this screen capture with something like ShadowPlay at 60 fps it captured it at ‘variable frame rate’. Then you most likely rendered at a ‘constant frame rate’ of 59.940 fps. If this is correct I would convert the source media file to constant frame rate 59.940 fps. You can do this with a free app likely MediaER Tool Kit, or within Vegas Pro. Then replace your original source media with this converted file, check the mask at each keyframe to assure proper alignment, then render your project out to 59.940 fps.

As Dimitrios ask is your render frame rate the same as your source?

To check the frame rate of your source you can use the free app Mediainfo (in Text mode), which can be downloaded from here….. https://mediaarea.net/en/MediaInfo

Woooow I’m not 100% sure but I can take a very sure guess the source file is originally 24 FPS and I recorded it at 60 FPS. That probably explains it but the weird part is I started a new project (File > New) and masked the same thing and when I rendered it the video was fine. I’ll try this though first thanks guys

Hi Leo,

I’m not following this line, “Woooow I’m not 100% sure but I can take a very sure guess the source file is originally 24 FPS and I recorded it at 60 FPS.”

Can you provide a bit more explanation as to what your workflow is?

I assume this is a game you play on your PC, correct? If so, you are using some type of screen capture application to record the game playing, is that correct?

Most of the games play at 60 fps so viewing is smoother during fast action. If your game is playing at 24 fps, it is going to appear to be jerky during fast action and there is no advantage to record at a higher frame rate.

With all that being said, I have never been one to argue with success, so if you are now getting the results you like, my questions are mute.

Best Regards……George

So I’m trying to record anime scenes and make a video of them. The clip I showed was of an anime movie where they usually have 24 fps. I’am using a screen capture program it’s GeForce Experience by NVidia and have it set to record at 60 fps which is probably why it’s messing it up. I still have problems with the masking so maybe I’ll try and record it at 30 fps since there’s no option for 24 fps.
