Projection Mapping Novice needs "presentation view"

@oillyoowen What is the frame size of your media (1920 *1080 etc)?
- What is the frame rate of your video?
- What is the target frame rate you set for Isadora?
- What is the native resolution of your projector?
- What version of the OS are you using?
- What version of Isadora are you using?
- Are you playing the files form an external disk? If so what is the connection and kind of disk inside the enclosure?
- When you are playing the video and showing the stages what are the readings for the cycles and FPS (bottom right corner of Izzy)?
H264 is a codec but it can have many many settings that can make it harder for your computer to decode (bitrates and profiles and iframe distribution), your computer is quite old not so powerful, a modern piece of software could well export a video that your computer will have trouble with. I would go for prores for sure.
I would also test with the isadora examples and see if the crashing still happens, they are pretty light on resources. I would guess that you are running out of resources trying to play and map this video, proress can make it easier on your machine, but depending on your needs, you may need access to something a little more up to date.
*What is the frame size of your media? 1280 x 800
* What is the frame rate of your video? 29.97
* What is the target frame rate you set for Isadora? I don't know how to set frame rate
* What is the native resolution of your projector? 1280 x 800
* What version of the OS are you using? 10.11.6
* What version of Isadora are you using? 2.5.2
* Are you playing the files form an external disk? If so what is the connection and kind of disk inside the enclosure? Yes: USB and I don't know
* When you are playing the video and showing the stages what are the readings for the cycles and FPS (bottom right corner of Izzy)? These are of course changing, but cycles: between 160 - 230; FPS: between 28 - 30
H264 was recommended by Ian Winters, who teaches Isadora (and is helping me a bit on this project), but I'll see if ProRes makes a difference.
Is there anything I can do to improve things short of buying a new computer?

@oillyoowen I would go first with prores and play the files from your internal drive, (USB 2 is super slow and most likely you have a slow drive in your enclosure) and see how it goes. You can test drive transfer speed with blackmagics disk speed test included in the decklink drivers for your platform.
H264 can be ok, but there are so many parameters for this codec it is not really enough to say h264. Proress is a little more locked down.
You can set the target frame rate in the preferences.
The stats show your machine is running out of power doing what you want, try prores, and if it still crashes I would test on another more powerful machine. I and many others certainly run heavy patches with Isadora all the time, I am guessing it is your machine that is doing it.
PS are you doing anything to the speed of the movie? If you just play the movie with a projector, no effects or mapping, how does it run?
@Fred OK, re-exporting now to prores, after shortening my piece as well...
I'm not changing the speed of the movie, no, and it plays fine sans mapping.
Can I upgrade my memory and expect to improve anything?
Thanks for all of your thoughtful replies!

@oillyoowen memory could help a little, generally SSD drives and a GPU will be the most effective, unfortunately you cannot upgrade the GPU but an SSD is possible.
Could you give us an update on this please?
Showing Stages should not cause a crash - there has to be something going on here to make that happen.
@Skulpture Sure, I had to sleep.
I wish I understood my issue well enough to give you a clear answer, but as I mentioned, I'm a novice. This is my first project in Isadora, and due to many circumstances, I now have today to work through it. Likely my computer is not robust enough to run the project as designed.
I have re-exported my media in prores and shortened my clips. This seems to be making the files run more smoothly.
Stages now does not result in what I'm calling "presenter view", or a full screen image from my physical projector, however. I don't understand why this feature sometimes works and sometimes doesn't.
Currently, that's all I know. I appreciate everyone's feedback very much.
If you open a support ticket, I will be happy to look at your file (you can share it and the media to me via dropbox or similar)
I will then be able to give you any recommendations I have. Without seeing the project/structure at this point its difficult to break down the issue/s any further than has already been done here.

FWIW, I've run complex mapping (well, complex to me) off older MBP's than the OP's. Something is amiss - probably from being new to the program. With a projector what you see is what you get. Size is relative.
"I need advice for this, I would like to know more. - added google translation by admin (skulpture)
I have had to google translate your question or else most of the people here will not be able to read it. I'm sorry that we do not support Thai(?) language natively here.
I deleted several different accounts that posted in Thai, even though the content does not explicitly seem to be spam, it is very suspicious that including today and yesterday there where about 6 different new users posting in Thai.
