Most of us who download scene releases don’t keep the original RARs, sample, NFO & SFV files after extracting the goodies inside. If you unpack and delete the RARs, there’s no way to get back to the originals without some major hacking - and even this doesn’t guarantee that the rar set will pass a proper CRC check when reseeding. But if you have the *.avi or *.mkv file, ReScene is a cool utility that lets users rebuild scene release NFO, SFV and RARs from a single extracted file back into their original scene format.
Scenarios for ReScene:
Use ReScene for:
Reseeding. Ever wanted to reseed a scene release, but all you have are the extracted files? Recreate those NFO, SFV and *.RAR files with ReScene. Even works with sample files.
Fill requests. Dig out that old DVD binder full of those data discs/AVI files and start filling scene requests.
Recreate official scene files from torrents you downloaded at trackers that don’t allow for RAR’d content. Mostly this refers to movie & HD trackers - PTP, TC, CN, HDBits - where often only the containers (*.avi/*.mkv files) are allowable.
Usenet & IRC. Leech from the newsgroups or XDCC bots, and reconstruct the releases to official scene files.
ReScene - How it Works:
In its simplest form, ReScene will process a group of scene release files and create a very small .SRR file. Within a .ssr file contains the NFO and SFV file - the SFV is specifically important since it contains the CRC (hash) values required to rebuild the original RAR files.
Anyone can use ReScene to create their own .srr files from scene releases (ie - for backing up a scene rls before extracting & deleting the rarset, nfo, sfv) but more importantly, ReScene has a large database of SRR’s so that users can rebuild their own scene files.
TIP: You’ll need figure out exactly which scene release (rls group) your avi/mkv source came from. For example, ReScene will not work if you try to recreate scene files from a .srr whereby your source *.avi file came from a P2P group (such as IMAGiNE) and the .srr is from a VOMiT release. It goes without saying; ReScene is intended for scene releases only, but fortunately there aren’t a lot of dupes.
What You’ll Need:
ReScene is a command-line application, so you’ll need to open a command (DOS) prompt. You’ll need:
• Download ReScene, and extract SRR.EXE into the folder of the *avi/*mkv that you want to make scene files from.
• Find the appropriate *.srr file for your scene release. These can be found on xvid.rescene.info.
The Reconstruction - An Example:
First, it’s a good idea to make certain that the .srr corresponds to your proper *avi file. In the .srr link, look at the file size for the *avi and compare it to the properties of your file. If it’s a match, you’re good to go!
For the example below, we’ll use Taking.Woodstock.DVDRip.XviD-DiAMOND. In the link (here) you’ll notice that the original movie filename (*avi file) is called dmd-takingws.avi. Most of us will probably have renamed this file to "Taking Woodstock.avi" so that we can recognize what the hell it is. ReScene (SRR.exe) will be looking for dmd-takingws.avi, but won’t be able to find it.
1. Move SRR.EXE and the .SRR file into your working directory containing your AVI file. (the alternative is to change to the proper paths in the prompt, but for the example we’ll simply move the two files). Run a command prompt and go into the correct path, and type:
srr Taking.Woodstock.DVDRip.XviD-DiAMOND.srr
Assuming that you did rename the AVI file originally, you’ll get an error message that dmd-takingws.avi could not be found:
So, rename "Taking Woodstock.avi" to dmd-takingws.avi. After renaming, enter the same command again. SRR.exe will do its work…
You’ll now have all the original rar files, as well as the SFV & NFO files (and perhaps a *sample.SRS) file in the directory. You can also re-check the files against the SFV - a simple way to do this is open dmd-takingws.rar and look at the CRC value for dmd-takingws.avi. Compare it to the value as reported on xvid.rescene.info for the same release/file.
Without renaming: If you want to leave the source filename the same (ie - "Taking Woodstock.avi"), then use the [-h] parameter:
srr Taking.Woodstock.DVDRip.XviD-DiAMOND.srr -h dmd-takingws.avi:Taking~1.avi
Other Parameters:
- -o [specifies output path, tells SRR to create the new files in a specific path]
- -p [tells SRR to recreate the folder structure. If it was preserved when the srr file was created, srr will do so]
- TIP: (use srr.exe in the command prompt to get a list of all parameters)
Recreating the Sample.avi File:
Not all releases will have a sample, but if they do, it’s likely that SRR will have created a resample (.SRS) file in your extracted directory. For our example, a file named dmd-takingws-sample.srs was created. These need to be handled separately from ReScene, and require Resample.
Download & extract ReSample to your path where the *.SRS file is located. Again, using the command prompt, enter one of two options:
srs dmd-takingws-sample.srs dmd-takingws.rar
OR do it from the AVI file, as seen in these two examples…
- srs dmd-takingws-sample.srs dmd-takingws.avi
- srs dmd-takingws-sample.srs Taking~1.avi
And presto! You’ll now have the sample. Again, adjust parameters & paths as needed.
Tips & Info:
No Subtitles: There’s no support for subtitles (these cannot be rebuilt using SRR) so if you’re attempting to reseed/cross-seed for the purpose of gaining UL ratio, you’ll need to finish downloading the subtitles in the torrent (if they exist in the original release). The torrent should normally pass CRC/hash (ie - the torrent will ‘hash check’ to 98-99% in the event that subtitles are needed), and the subtitle folder & files will then be downloaded to ‘complete’ the torrent before it begins to seed. This is not much of an issue, since most subs are under 10 MB.
Reseed tips: Either use proper path parameters in SRR (and SRS) so as to match up with the official scene release, or else create/rename paths (and compare this to the file list in the torrent details). Be mindful of ‘2CD’ releases that have CD1/CD2 dirs.

GUI: For those who prefer a visual approach, there’s also an unofficial GUI for ReScene, download it from here.
