This is so frustrating. In Google Flow, when you generate a 16:9 image with nano banana and then use that image to generate a video, you get an EXACT SAME black bar on the right side of the video every time. Seems like they have a slight difference in aspect ratio, which is why this happens.
Aspect ratio of the image is: 1344 x 768
Video is 1280 x 720
Come on now, Google, this tool costs $250 per month, and its own image generator is unusable, creating black bars? This is not serious.
Hello,
Based on the details provided, we attempted to reproduce the issue, but the service appears to be functioning as expected. Although the resolutions of the image and video differ, they maintain the same aspect ratio, and no black bars were observed.
If you are still facing this issue, please provide the exact prompts and configuration used to generate the black bars so we can assist further.
The black bar on the right side of the video occurs because the aspect ratio of the generated image (1344 x 768) is slightly different from the video resolution (1280 x 720). The image is wider than the video, so when it’s placed in the 16:9 frame, the black bar appears to fill the space. To fix this, you could resize the image to match the video resolution (1280 x 720) or crop it to fit.
Am facing the same issue and the real problem is when we upload our frames (images) in flow to generate video, Flow’s cropping mechanism is not 100% accurate. I tried multiple times to crop the images to 9:16 (Vertical) and the Flow’s cropping mechanism sucks and forces me to extra-crop the image manually and if i don’t do that, it creates thin black bars on the sides of the video which wastes my extra time in editing software to crop it if i didn’t do it in flow.
Solution Anticipated: Flow’s cropping mechanism should crop the image to 100% in the selected ratio.
