I'm wondering if anyone has encountered this issue as it's really being a huge problem and I have a looming deadline.

Essentially, I have a umenu, which is sending videofiles into an [poly~ ]containing an abstraction with a [jit.gl.cornerpin]. The issue I'm having is that the file initially loads in low res / pixellated and not in the correct aspect ratio. If I load in the file a second time (i.e., clicking the name of the file in the u-menu, it fixes it. I'm using @perserve_aspect 1. I have to load files in dynamically because the patch has "scenes" where I'll need to go through different banks of video.

Please note, I have a specific file naming protocol as I need specific video files during specific scenes and am trying to call from a bank of videos based on cues from a microcontroller. Here is a link to a drive containing a folder with the naming structure I'm using in my abstractions with some sample video compressed as HAP Alpha 1080p: https://drive.google.com/open?id=1E7AIyfuSJ5l8IubXYrTdUK0hu9tfmN3Q

The patch is a bit messy / work in progress.

I have attached the project without media in this post which is a smaller download.

 Files are 1920 X 1080 HAP Alpha.

Essentially

jit·gl·cornerpin-loads-files-pixellated-blend-enable-not-always-working

is it just a single frame that comes out at the wrong resolution? meaning are you loading the files with autostart 0, and banging out the first frame?

The entire video will play in low resolution. If I then click the umenu again and load in the video, it then plays in the correct resolution. 

1) autostart 0, with a start message after the files is read (via route read)

6) Trying the abstraction outside of the poly~

7) This all lives in a subpatcher, so de-encapsulating just to see if there's some random wierdness with the plane not being in the root patcher.

Attached are screenshots of the problem. Note the background is a seperate layer than the character.

It will first load pixellated (image 1). Sometimes it loads some layers pixellated, and some not (image 2). The final pic is after clicking the file in multiple times (image 3).

I have tried:
1) autostart 0, with a start message after the files is read (via route read)
2) autostart 1
3) jit.gl.cornerpin @preserve_apect 1
4) jit.gl.videoplane @transform_reset 2
5) trying viddll, as well as HAP

I think I may have found the bug! I am unsure of the best workaround is and do need one stat with a looming client visit :D

I think the issue are the shaders I've been using. It's the @file co.normal.jxs which is pretty standard. Basically the way my patch works, is there are two jit.mov's and they fade when a new movie is loaded in so that I can tween between different animation states. I just did an experiment where I bypassed it. Reloaded the patch multiple times for good luck and it seems to have resolved the issue. 

I need to look at shader alternatives as the fade is essential. I tried [jit.gl.pix @gen xfade] and the problem persists. On fix I have is not using output_texture 1, but then my frame rate plummets pretty harshly (i.e., 10 fps from 60fps)

I'd prefer to keep using @output_texture 1 for efficiency and I'm uncertain whether this is part of the issue.

Any insight? 

hmmm, sounds like a patching issue. if you can isolate that part of your patch into a simple example, we can figure out if it's a bug or a patch problem

I looked into it a bit more. It appears the problem was that I was clearing jit.movie, sending a fade message between two video sources (i.e., to the shader) before the file was read in. I'm assuming the clear made the two kind of "unknown" sometimes dimensions so it made it pixellated as it was interpolating between one 1920 X 1080 and a cleared jit.movie.

One problem that has arisen is that I need to clear the videos between scenes, if I clear or use dispose to jit.movie I get a black frame. My current hack is instead of clearing jit.movie with clear or dispose is sending it a blank alpha .png with nothing in it so that one of the sources is transparent. Does anyone know of a more elegant way of doing this in Max bearing in mind I'm trying to keep everything as textures for speed and efficiency?

Thanks for the reply!

seems like a fine soultion. alternatively you can just have a named matrix (jit.matrix clearmat 4 char 1920 1080) that you bang into your slab/pix inputs whenever you want to clear, with the message "jit_matrix clearmat".

jit.gl.cornerpin loads files low resolution, blend enable doesn't always work.
