Rendering big images about stitchem HOT 2 CLOSED

Several things to consider when rendering large outputs:

1. the GPU memory can be the limiting factor, as all of the stitching happens on the GPU, and the GPU memory can't be paged or swapped out. The 6 GB of your GPU should be enough to stitch 11k x 5k, unless you have a large number of gigantic inputs. Have a look at the GPU memory usage information on the bottom of the window. If you're getting close to using half the GPU memory, then use the Batch Stitcher for rendering: Process Tab -> Send to batch, and close Studio before hitting the "Stitch" button to free up GPU memory from having the project opened in Studio.

2. Outputs above 4096x2048 can't be encoded into h264 (#81). Choose MOV container ("Format"), and either Motion JPEG or ProRes as the Codec. (MPEG2 works above 4K, but I think not above 6k or 8k or something like that). If you desire another output format, you'll have to manually reencode the result, e.g. with ffmpeg.

3. Give both of the output dimensions a multiple of 16. Try 11008 x 5504 instead of 11000 x 5000. In theory every even value should work, but in practice some part of the pipeline, e.g. the encoder, might barf if it's not aligned to some block size, so go with the multiple of 16 to be safe. Also consider the "Set optimal size" button, which chooses the output size to get the full resolution of the inputs in the output frame, but not more.

Thank you for the quick reply!
I did not have to check all your solutions, because the first one helped :) I checked the consumption of dedicated GPU memory and it did not exceed 3.9 of 6GB available.
