First, thanks to everyone for their suggestions and tips!! I'm going to
describe my procedure and test results in detail for the benefit of
people reading this post in the future.

Here's my current setup:

_*Computer: *_
Macbook PRO 2.3 GHz i7
OS X 10.9.5


How much memory and disk space?


_*Test Video:*_
clip0076.mov
- 1080p 59.94fps
- movie is approx. 1 min 52 sec, 6,711 total frames
- file size is 419.9 MB


I'm using Hugin 2014.0.0 installed in /Applications/Hugin

I created a file named "hugin" in my paths.d folder with these paths:
/Applications/Hugin/Hugin.app/Contents/MacOS
/Applications/Hugin/Hugin.app/Contents/Resources
/Applications/Hugin/Hugin.app/Contents/Resources/HuginStitchProject.app/Contents/MacOS

This lets me run nona from the command line without having to type the
full path

I installed FFmpeg using Homebrew:
https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX



_*TEST RESULTS:*_

1. Use FFmpeg to split the movie into a folder of numbered images:


METHOD 1 - lossless PNG

ffmpeg -i clip0076.mov frame-%05d.png

- 21 minutes to create 6,711 PNG files totaling 29.81 GB (70X the
original file size!)


METHOD 2 - high quality JPG

ffmpeg -i GOPR0076clip.mov -qscale:v 2 frame-%05d.jpg

- LESS THAN 2 minutes to create 6,711 JPG files totaling 3.88 GB (more
reasonable)


2. Use Hugin to convert all of the images to Equirectangular Panini:

Here's the bash script (slightly modified from Carlos Cartola's suggestion):

# loop on the frames
for number in $(seq 1 $total); do
  n=$(printf %05d $number)
  echo $n
  nona -o out-$n /Users/design215/Video/_hugin/test.0001.pto frame-$n.jpg
done


test.0001.pto is a Hugin .pto file that I edited. I'm using this single
.pto file to modify all of my images because the loop feeds each
filename to the .pto file.

- 1 HOUR, 4 minutes to create 6,711 corrected JPG images
- Images are all 2250x1362. I prefer to crop in Premiere, not Hugin


3. Use FFmpeg to combine the corrected images back into a movie:

ffmpeg -framerate 59.94 -i out-%05d.jpg -pix_fmt yuv420p -c:v libx264
-crf 16 output.mp4

- 8 minutes to create output.mp4
- These settings give me the original framerate, and high quality output

output.mp4:
- 2250x1362p 59.94fps
- file size is 703.6 MB
- quality looks good!


_*CONCLUSION:

*_The total time to do the conversion with my 2 minute clip = 1 hour, 33
minutes using PNG images, or 1 hour, 14 minutes using JPG images.

Hugin gives me complete control over the projection and I can do exactly
what I want.

The downsides to method are:
- My test clip was less than 2 minutes. Imagine the space you need for a
10 minute clip.
- The images are re-compressed multiple times. Even if you start with
PNG images, they are compressed once by Hugin, and again by FFmpeg when
merging the images back to video. I know I could have Hugin output PNGs
but then I would need at least 60 GB just to process 2 minutes of footage!

Don't get me wrong, the final video quality is VERY GOOD!

But, I can do almost the same thing in Photoshop CS6 with fewer steps
and no folders with thousands of files.


Only cuz PS is doing essentially the same thing in memory.


The downsides to using Photoshop are:
- It takes just over 2 hours to process the same 2 minute clip.
- I have much less control than I have with Hugin. I can get close but
not exactly what I want.

My feeling is- There HAS to be a better, more efficient way to do this.


Thanks for the info, interesting steps and process. Not being a fan of 
Adobe products in general but being a fan of quality, I'd prefer the PNG 
> Hugin > PNG > ffmpeg.


Only 60GB for 2 minutes? Hate to tell you this, but video takes a lot of 
space. My budget laptop here has a 750GB hard drive. Most laptops now 
come with 1TB. So 60GB doesn't seem like much. Backups of my current 
home folder (I run Linux) are about 60GB ... without any videos or MP3s 
in it. But maybe I'm just weird.

There is a "defish" effect on Kdenlive, but I really don't know if it can
do what you need. You can test Kdenlive runnint linux on a pendrive if you
can't install it on your Mac.

Carlos, that is excellent!!

Since I'm passing each filename to nona in the loop, can I just use a 
single test.pto instead of test.$number.pto ??

Re: [hugin-ptx] Re: Can Hugin change the projection of a video?

2016-07-11 Thread Carlos Eduardo G. Carvalho (Cartola) 
There are many documentation on the Internet on how to make a bash script. Here
is one example .

I guess here you will need basically a loop:

---
#!/bin/bash

for number in $(seq -w 1 18000); do
  /Applications/hugin.2014.0.0/Hugin.app/Contents/MacOS/nona -o output
test.$number.pto test.$number.png
done
---

And if you install ffmpeg you can automate all the job

---
#!/bin/bash

# split the video in frames using 5 digits
ffmpeg -i yourVideo.mp4 -qscale:v 2 frame-%05d.jpg

# count the frames
total=$(ls frame-*.jpg | wc -l)

# loop on the frames
for number in $(seq -w 1 $total); do
  /Applications/hugin.2014.0.0/Hugin.app/Contents/MacOS/nona -o output
test.$number.pto frame-$number.jpg
done

ffmpeg -i output%05d.jpg final_output.mp4

Re: [hugin-ptx] Re: Can Hugin change the projection of a video?

2016-07-11 Thread Robert Giordano 
Thanks!! That works!! I was playing with the "Write PTStitcher Script" 
option in the Hugin File menu and now I have this:
 

# PTStitcher script, written by hugin

p f16 w2250 h1362 v111  n"JPEG q94"
m g1 i0 f0 m2 p0.00784314

# output image lines
o w1920 h1080 f2 Tpp0 Tpy0 TrX0 TrY0 TrZ0 a0 b0 c0 d0 e0 g0 p0 r0 t0 
v102.88718987 y0  n""


I changed to the JPEG option and added q. Now I just have to figure out how 
to make a batch script.

Thanks everyone, this has been very interesting so far!!

Your .pto file has the line:

p f16 w2250 h1288 v111  E0 R0 n"TIFF_m c:LZW r:CROP"

The n option controls the output file format, use n"JPEG_m" for JPEG
output. The c: and r: options aren't available with JPEG and the
compression factor may be defined by adding a q: option.

There should be a nona.txt file inside the "doc" directory of your Hugin
installation which explains the options in a .pto file.

Okay this worked:

/Applications/hugin.2014.0.0/Hugin.app/Contents/MacOS/nona -o output 
test..pto test..png

and it produced output.tif

I'll have to figure out why it created a .tif instead of a .jpg

You can do all this with a single PTO template. No need to rewrite the filename 
inside because nona allows you to specify the input filename on the command 
line:

  nona -o output1234 template.pto input1234.jpg

Re: [hugin-ptx] Re: Can Hugin change the projection of a video?

2016-07-11 Thread Robert Giordano 
Thanks again Sean,

The methods you suggest are logical. That's pretty much how I attack
problems anyway. I was hoping there was a direct command to transform the
projection of an image. That would be a lot simpler (and probably faster as
far as CPU cycles go) than using the entire Hugin program.

I will try making a .pto and inspect it. It might give me some clues.

I also want to mention that I found a way to do what I want in Photoshop
CS6 but its also a bit inefficient. I could not find a way to do the
equirectangular panini directly in PS so I used several filters to achieve
a similar result. Since the images are all the same size and shape (they're
all video frames) my sequence of adjustments can be repeated across all of
them.
- I open the video file in PS and make it a "smart layer"
- I apply my sequence of filters to it (they are not applied immediately)
- I select "render video" and choose my video output options
- Then I wait just over 2 hours for PS to process 2 minutes of footage
(7200 frames) but then I have a complete .mov file.

So, the drawbacks of using PS are
1) its close but not exactly what I want, while Hugin does exactly what I
want in a single step, and
2) it takes forever and I have a fairly fast Mac.

I haven't timed how long it will take to export a video to 7200 separate
images from Premiere but that will play a factor.

I've also wondered how hard it is to make a plugin for Premiere. With all
of the thousands of things you can do in Premiere (or After Effects) I was
surprised I couldn't find a plugin that would let me change the projection
of a video. Maybe there is but I wasn't able to find it after 2 solid days
of searching.

I'll post what I find as I experiment with the .pto file in case it can
help others in the future.

PHP is not typically used for this sort of thing, so don't worry about
it.

Unfortunately, I'm not very familiar with OSX. I do believe it has bash,
so pretty much any bash tutorial should help you. I like this one:

My best advice here is to make a project with Hugin that does what you
want, then save the .pto file and inspect it. Then either turn that file
into a template or model your pto generation code after it.

Best way to tackle something like this is to draw out the overview of
what you want to happen. e.g.:

loop over files:
generate pto with current file name
run nona / hugin_executor / whatever
move file to destination folder
delete pto file

Once you have that, then start implementing a bit at a time. Breaking
the problem up makes exploring unfamiliar territory easier.

Have a look at pano_modify, it might help...but it does its work on a .pto

2016-07-10 Thread Robert Giordano 
Thanks Sean and Zoilo

I'm doing video editing on several Mac computers, OSX 10.9.5. I won't be
able to install PHP on them so I'm guessing I will need a bash script?

I'm not an expert at command line scripting. Is there a place where I can
read about command line options for Hugin? For example, is there a direct
command to change the projection of an image, given the lens and HFOV
parameters? Or do I have to create a .pto file just for this single
operation?

I could probably look up how to get a list of files in a folder but then I
might need some help after that.

thanks,

Robert

Sure, you can generate a .pto file using any scripting language, even
PHP (though I would imagine python or even bash might be a bit simpler).

Basically, you need a script that loops over every frame file, generates
the pto, processes it, and saves the output file with the proper name.
If you get clever with the script, it could scan a directory and process
all files in it. That way, you just explode the video into a directory,
then fire off the script.
