Hello from across the pond.

This is the full resolution over-scanned 2080x870 pixels x 24bit depth sequential jpegs source file converted to MPEG4 for viewing purposes regarding the inaugural UltranPan8 test film roll recently uploaded.

This newest upload removes an additional level of compression, i.e.

1. original upload conversion/compression path:
UltraPan8 film -> 2080x870 pixels x 24bit depth sequential jpegs -> DIVX (mpeg4) 2.8:1 extraction -> YouTube/Vimeo compression

2. New upload conversion/compression path:
UltraPan8 film -> 2080x870 pixels x 24bit depth sequential jpegs -> YouTube/Vimeo compression

Bolex hybrid H8/H16 camera mod provided by Jean-Louis Seguin. The scan was delivered by John Gledhill of bitworks.org utilizing his sprocketless 16mm transfer bay. Note that the ultra-wide native frame dimensions of UltraPan8 = 10.52mm x 3.75mm w/ AR = 2.8:1

The file is also available for public download and examination here, i.e. http://dl.dropbox.com/u/29307178/Squential%20JPEGS%2018fps%20MPEG4.mp4

Note the impressive density of information contained in this minimal latitude reversal film stock, i.e. Ektachrome 100D.

Nicholas,

Beautiful! And to think I traded away my Bolex H-8 Rex 3.....

I never thought of Canada being "across the pond" from the US, but then again, there are those great ponds Huron, Erie, Ontario, Michigan and Superior.

Thanks, Doug!

Sad to hear of the loss of your Bolex Rex 3. [Frown]

The modification is much cheaper than Super 16. Significantly.

I was under the impression that this forum is hosted in the UK? Is this incorrect?

More to come as I just sent off my latest test roll to be scanned.

Onward!

Very impressive. However you call the Ektachrome 100D stock 'minimal latitude' stock. I think this is true in relation to negative stock. But it's my impression that Ektachrome 100D boasts a surprising latitude for a reversal stock. In 'run and gun' situations with automatic metering, it is a lot more forgiving than Kodachrome and most of the time results in decently exposed footage. This was the biggest surprise for me when starting to use 100D.

Hi Alexander.

Indeed. In contrast to the increased latitude of specific Vision 2/3 200T Super 8 negative stock of which I have shot many rolls. I am looking forward to reperfing this negative stock to the UltraPan8 format.

But I concur that when one hits the sweet spot with E100D on a bright sunny day ..it can be quite impressive. Reminds of Kodachrome 40's classic and almost identical response to similar shooting conditions.

Nicholas,

Although we proudly have members from all over the world, the 8mm Forum is based/hosted in the US.
