Help with printf/regular expression, please!

[colinhunt]

Whoo boy, it's been a while since I last felt this dumb. (Must be several hours, in fact.)

I'm trying to encode a bunch of TIFF images using x264, but can't wrap my head around how to feed the images to the encoder. I'm sure there's a regular expression or a printf thingy I should use but no matter what I try, I get error messages.

A sampling of filenames:

A004_C014_011375.0001583.tif
A004_C014_011375.0001584.tif
A004_C014_011375.0001585.tif
A004_C014_011375.0001586.tif

and so on. In other words, it's only the last 4 numbers that change.

These don't work, for example:

x264.exe -o output.mkv A004_C014_011375.%07d.tif
x264.exe -o output.mkv A004_C014_011375.000%04d.tif

I also tried to use an Avisynth script as a source, using ImageSource to read the TIFF files, but get only errors.

What's the syntax I should use?

Thank you!

Does x264 really support regular expressions in file names on the command-line? Also what I see in your example, is NOT a regular expression (http://qt-project.org/doc/qt-5.0/qtcore/qregexp.html#details) :confused:

Anyway, I think for your case the correct ImageSource() call would look like:
ImageSource("A004_C014_011375.%07d.tif", start=1583, end=1586)

If you get errors with ImageSource, what errors do you get?

Yeah but guess what? I haven't got the foggiest idea what I was talking about there. It was the result of a couple of hours of googling and experimenting. Found some pages where people had got those %d thingies to work on the x264 command-line, and others where everyone said x264 does not support them. So that's me stumbling around in the dark, bumping into things with sharp edges.

x264 could not load Avisynth, even though the build I use ought to have support for Avisynth. Anyhoo, thank you for that, I'll give it a shot.

Do you have Avisynth installed?

Also, be aware that 32-Bit x264 needs 32-Bit Avisynth, while 64-Bit x264 needs (the still experimental) 64-Bit Avisynth. Mixing 32-Bit and 64-Bit is not possible.

If you have 64-Bit x264 and want to use the stable 32-Bit Avisynth, you need to go the avs2yuv (http://komisar.gin.by/tools/avs2yuv/avs2yuv-0.24bm2.zip) route:

avs2yuv.exe c:\foo\bar.avs | x264.exe [options] -demuxer y4m -

Certainly.

Indeed. For some reason the 32-bit builds I had downloaded did not support Avisynth, but then I discovered Komissar's latest 32-build which did.

After a wee bit of experimenting with different workflows, I discovered a working solution involving Apple's ProRes HQ (with a bitrate of 600Mbps in this case) and an .avs script using QTSource. I wanted to see how x264 performs in 4K when it's given only 25mbps to work with.

Thanks for taking the time to educate an ignoramus, LoRd_MuldeR.
