Overwriting a file

Apr 08 2011 | 7:18 am


I use the write message to create a new .mov file, but I would like to have the option to overwrite the file. (I use the .mov to do some background substraction using the ‘jit.op’ object).

So, how do I overwrite a .mov file inside Max?

it should overwrite automatically.
however, your patch is incorrect. you can’t read a movie immediately after writing in that way. you must use jit.qt.record’s write notification to trigger a read message. this ensures that the file has been closed before it’s opened again. this may be the cause of the problem you were experiencing.
if not please send an email to support.

did you find out how to overwrite a file with jit.qt.record?
it does it automatically in macos,
but I can’t get it to work on windows.

Sorry for pushing this old thread. It seems that in Max7 something has changed… jit.record (the avf version) does not overwrite an existing file or am I missing something?

this is a limitation of the AVF version of jit.record.

for now, you can try the VIDDLL engine instead, which does not have this limitation. you can find info on the viddll engine in the jit.record help file tab in the latest max 7.2.4.
