Short videos

Hello! I tried uploading a 10-second video, but the output is a very short video that lasts about a second. What could be the problem?

Check if you have not a frames limits on the load video node or something similar somewhere

Hello! I tried uploading a 10-second video, but the output is a very short video that lasts about a second. What could be the problem?

Did some digging, please correct me if I'm wrong as I'm also looking for an answer;

• In the Load Video (Upload) node, the "frame_load_cap=16" will only load 16 frames in for interpolation in the VEnhancerSampler.
• "select_every_nth=1". Assuming your are using a CogVideoX output (which can do up to 8FPS), we are taking >every< frame, which means we only get the first 16 frames to run (8FPS x 16 frame cap = 2 second long clip ie. a short video).

The above can be verified when comparing the input count in the "Get Image Size and Count" node, and the same node after it's been upscaled. Trying to uncap the "frame_load_cap" results in a runout of VRAM (4090), so there is likely a more suitable answer in another node.

The only solution I have (again, assuming this is an output of CogVideoX5B, otherwise I'm not sure) is the following;

• Given the video output is 6 seconds, and assuming we can only use the frame_load_cap of 16, we can set "select_every_nth=4", meaning 2 frames are sampled per second, across 6 seconds = 12 frames, underneath the load cap of 16.
• Set "input_fps=2" to reflect above changes will still result in a VRAM allocation error.

It seems like I'm on the right track, but my VRAM errors are creating more problems than I imagined. Will have to keep plugging away and see what I can find.
