Batch Processing and Canvas Size

[Lucas Krech]

I am doing a test run of a PASeq on some video for an upcoming project. What I would Like to have happen is each canvas be in the native dimensions of the source images and deal with rescaling/proportions after the SA processing. However, it appears that the batch processing tool only allows a single file size.

There are a couple of reasons for this. First the source images are of varying proportions so there is unwanted distortion caused by reconfiguring each video to the same dimensions. The other issue is speed. The files at or near the canvas size process *much* faster that ones way out of scale.

I suppose one way to resolve this would be to make all the source files the same dimensions ahead of time so at least that step was averted and the processing would go faster.

But what I would love to do is have the canvas resize every time a new source files starts to match the dimensions of the source file. Is that possible?

Suggestions?

Previous versions of Studio Artist did allow you the option of resizing or keeping the original canvas sizes when batch processing. Version 4 currently always resizes to the current canvas size.

I can look into giving you both options again in a future release. People have asked for this for gallery show as well.

Thanks for the reply!

So I have had this problem three times now where the processing slows down midway through the batch processing. At the beginning the PASeq is taking maybe 1 sec per frame or less. I set it to go and go to sleep. Wake up to check on progress, or come back from running errands, and it is taking upwards of 6 seconds per frame. The video files are (now) the same dimensions as the target and all files are the same dimensions. It is still running the first PASeq in the folder of PASeqs.

I have 46 files (each between 10 seconds and 90 seconds) that I want to process with 5 PASeqs. The slowdown seems to happen around the 30the file.

If you email me the PASeq you are using, i can run a few tests here.

What's the compression codec you are using for your source video?

[Lucas Krech]

Source video are half Photo-JPEG and half H.264 but they alternate as I have two versions of each source so it's gone halvsies on codecs up to the slowing down point. So I assume problem is independent of the codec.

Attached is the PASeq. It's a very simple two step to bring in a source image from video and then run an MSG. Could be a one step but is an artifact from an earlier iteration of the PASeq.

Again the problem occurs over time as it works fine for the first 15-30 movie files.

Thanks for the help!

I seem to have figured out the cause of the stall. It is one video in particular that slows the whole process down. Not sure why. It was run through Compressor on the same batch with the same settings as all the others. None the less, so long as I pull this one out of the batch it works fine.

Thanks for your help in resolving the issue.
