Hi – thanks for replying. Yes, Syphon Recorder.
1. I’m using the latest version: Syphon Recorder v 13 + in Processing, imported library codeanticode.syphon (beginning to wonder if this is the problem now …)
2. screenshots here https://docs.google.com/document/d/1IgPtPsC02k4QpD3SRiZwK227wKvGmVbUbyBRFqQMIy4/edit The preferences settings are just an example – it occurs at c. 4.3 GB into any setting that generates a file that exceeds that size (e.g. have tried larger window size, uncompressed, AAC …) ‘The operation couldn’t be completed. File too large’ (Syphon Recorder pop up.
Works fine with any setting where the file generated is < 4.3GB in total.
Have tried writing to internal and external HD.
